PLA on l\u00fchend s\u00f5nast Pol\u00fc\u00fcsimakshape, mis on teatud t\u00fc\u00fcpi biolagunev plastik. Seda s\u00fcnteesitakse tavaliselt kunstlike keemiliste protsesside abil, kasutades selleks taimseid materjale, n\u00e4iteks maisit\u00e4rklist. PLA-l on suurep\u00e4rane bioloogiline sobivus ja biolagunevus.<\/p>\n\n\n\n

Kuidas PLA valmistatakse?<\/strong><\/strong><\/h2>\n\n\n\n

PLA tootmine h\u00f5lmab tavaliselt j\u00e4rgmisi etappe:<\/p>\n\n\n\n

\"plastikust<\/figure>\n\n\n\n

Tooraine ekstraheerimine<\/strong><\/strong><\/h3>\n\n\n\n

PLA on saadud taimedes leiduvatest suhkrutest. Esimeses etapis eraldatakse taimedest suhkrud, kasutades sageli selliseid materjale nagu maisit\u00e4rklis ja sahharoos. Need materjalid valitakse nende k\u00f5rge suhkrusisalduse t\u00f5ttu ning maisi ja suhkruroo kasvatuspiirkonnad on laiad ja nende saagikus on suur, mist\u00f5ttu on need toorained kuluefektiivsed.<\/p>\n\n\n\n

\"mais\"<\/figure>\n\n\n\n

H\u00fcdrol\u00fc\u00fcs<\/strong><\/strong><\/h3>\n\n\n\n

T\u00e4rklis ja sahharoos on pol\u00fcsahhariidid. Et neid kasutada PLA tootmiseks toorainena, tuleb need ens\u00fc\u00fcmide abil gl\u00fckoosiks h\u00fcdrol\u00fc\u00fcsida.<\/p>\n\n\n\n

K\u00e4\u00e4ritamine<\/strong><\/strong><\/h3>\n\n\n\n

H\u00fcdrol\u00fc\u00fcsitud gl\u00fckoos l\u00e4bib \u00f5iges keskkonnas bakterite, tavaliselt piimhappebakterite tegevuse. See protsess muudab gl\u00fckoosi piimhappeks.<\/p>\n\n\n\n

Piimhappe pol\u00fcmerisatsioon<\/strong><\/strong><\/h3>\n\n\n\n

Piimhape pol\u00fcmeriseerub, et moodustada pol\u00fcpiimhapet (PLA). See protsess h\u00f5lmab kondensatsioonireaktsioone, mille k\u00e4igus piimhappe molekulid \u00fchenduvad omavahel pikkade ahelate moodustamiseks, mille tulemusena tekib l\u00f5puks pol\u00fcmeer PLA.<\/p>\n\n\n\n

Pelleti moodustamine<\/strong><\/strong><\/h3>\n\n\n\n

PLA pol\u00fcmeer t\u00f6\u00f6deldakse graanuliteks, mis on toorainena erinevate toodete valmistamiseks.<\/p>\n\n\n\n

Mis <\/strong>A<\/strong>re <\/strong>T<\/strong>ta <\/strong>T<\/strong>PLA t\u00fc\u00fcbid?<\/strong><\/strong><\/h2>\n\n\n\n

Pol\u00fcmet\u00fc\u00fclhapet (PLA) v\u00f5ib selle keemilise struktuuri alusel liigitada erinevatesse kategooriatesse:<\/p>\n\n\n\n

PLLA (pol\u00fc-L-ma piimhape)<\/strong><\/strong><\/h3>\n\n\n\n

PLLA on PLA k\u00f5ige levinum vorm. Sellel on k\u00f5rgem sulamistemperatuur ja k\u00f5rge kristallilisus. Seda kasutatakse sageli stsenaariumides, mis n\u00f5uavad suurt tugevust ja j\u00e4ikust, n\u00e4iteks meditsiiniliste implantaatide ja \u00f5mblusmaterjalide valmistamisel.<\/p>\n\n\n\n

PDLA (pol\u00fc-D-piimhape)<\/strong><\/strong><\/h3>\n\n\n\n

In contrast to PLLA, PDLA has a lower melting point and lower crystallinity. It is rarely used alone but is often mixed with PLLA to adjust the material’s properties, enhancing PLLA’s performance, such as improving flexibility.<\/p>\n\n\n\n

PDLLA (pol\u00fc-DL-piimhape)<\/strong><\/strong><\/h3>\n\n\n\n

PDLLA is a mixture composed of both PLLA and PDLA. The combination results in varying degrees of changes in the material’s mechanical strength, crystallinity, biodegradability, etc. This versatility allows PLA to find widespread applications in different fields, including packaging, biomedical applications, 3D printing, and more.<\/p>\n\n\n\n

PLA omadused<\/strong><\/strong><\/h2>\n\n\n\n

K\u00f5rge j\u00e4ikus<\/strong><\/strong><\/h3>\n\n\n\n

PLA on materjal, mis on tuntud oma suure j\u00e4ikuse poolest, mist\u00f5ttu sobib see erinevateks konstruktsioonilisteks rakendusteks. See sobib ideaalselt kergete, kuid tugevate komponentide valmistamiseks.<\/p>\n\n\n\n

Madal sulamistemperatuur<\/strong><\/strong><\/h3>\n\n\n\n

PLA-l on madal sulamistemperatuur, mist\u00f5ttu on see v\u00e4ga h\u00e4sti t\u00f6\u00f6deldav. Selle v\u00f5ime sulatada madalamal temperatuuril muudab selle populaarseks valikuks s\u00fcstevalu ja 3D-printimise jaoks.<\/p>\n\n\n\n

Head esteetilised omadused<\/strong><\/strong><\/h3>\n\n\n\n

PLA-l on hea l\u00e4bipaistvus ja l\u00e4ige, mille tulemuseks on esteetiliselt meeldivad tooted, kui seda kasutatakse toorainena. Lisaks on selle tekstuur siledam kui paljudel teistel plastidel, mist\u00f5ttu sobib see dekoratiivsete esemete valmistamiseks.<\/p>\n\n\n\n

Madal UV- ja temperatuurikindlus<\/strong><\/strong><\/h3>\n\n\n\n

PLA has relatively poor resistance to UV rays and high temperatures. Therefore, this material is not suitable for prolonged exposure to sunlight or high-temperature environments. It’s crucial to consider this aspect when using products made from PLA.<\/p>\n\n\n\n

Keemiline vastupidavus<\/strong><\/strong><\/h3>\n\n\n\n

PLA has good resistance to typical acidic and alkaline substances (such as hydrochloric acid, sulfuric acid, sodium hydroxide, etc.). However, stability may vary in different chemical environments, so it’s advisable to follow the manufacturer’s recommendations when using or storing PLA-made products.<\/p>\n\n\n\n

M\u00f5\u00f5tmete stabiilsus<\/strong><\/strong><\/h3>\n\n\n\n

PLA s\u00e4ilitab m\u00f5\u00f5tmete stabiilsuse tootmis- ja kasutusprotsesside ajal, minimeerides m\u00e4rkimisv\u00e4\u00e4rseid deformatsioone.<\/p>\n\n\n\n

Kristallilisus<\/strong><\/strong><\/h3>\n\n\n\n

As a semi-crystalline polymer, PLA’s crystallinity influences its physical properties. Higher crystallinity generally implies increased strength and hardness.<\/p>\n\n\n\n

Tugevus<\/strong><\/strong><\/h3>\n\n\n\n

PLA-l on suur tugevus, mist\u00f5ttu sobib see mitmesuguste rakenduste, sealhulgas protot\u00fc\u00fcpide ja konstruktsioonielementide valmistamiseks.<\/p>\n\n\n\n

PLA eelised<\/strong><\/h2>\n\n\n\n
\"pla<\/figure>\n\n\n\n

Taastuv ressurss<\/strong><\/strong><\/h3>\n\n\n\n

PLA is a renewable resource because its main raw materials come from plants. In contrast to conventional plastics, which are derived from petroleum, PLA’s use of plant-based materials makes it more environmentally friendly, reducing waste of natural resources.<\/p>\n\n\n\n

Madala s\u00fcsinikuheitega heitkogused<\/strong><\/strong><\/h3>\n\n\n\n

PLA tootmisprotsessis ei kasutata fossiilk\u00fctuseid, mist\u00f5ttu on tootmise k\u00e4igus v\u00e4hem s\u00fcsinikdioksiidi heitkoguseid ja v\u00e4heneb s\u00fcsiniku jalaj\u00e4lg.<\/p>\n\n\n\n

Biolagunevus<\/mark><\/a><\/h3>\n\n\n\n

PLA v\u00f5ib \u00f5iges keskkonnas looduslikult laguneda, tekitamata keskkonnale kahjulikke aineid. See ei p\u00fcsi pinnases ega merevees, v\u00e4ltides pinnase reostust v\u00f5i kahjulikku m\u00f5ju mereelustikule.<\/p>\n\n\n\n

Mittetoksiline<\/strong><\/strong><\/h3>\n\n\n\n

The production of PLA typically doesn’t require the use of toxic additives or catalysts. Therefore, PLA is non-toxic and does not emit harmful gases during its application in areas such as medical equipment or video packaging.<\/p>\n\n\n\n

Puudused<\/strong> PLA<\/strong><\/strong><\/h2>\n\n\n\n

K\u00f5rgemad kulud<\/strong><\/strong><\/h3>\n\n\n\n

V\u00f5rreldes tavalise plastiga on PLA-l suuremad toorainekulud ja keerulisem tootmisprotsess, mille tulemuseks on k\u00f5rgemad tootmis- ja kasutuskulud.<\/p>\n\n\n\n

Madal kuumuse stabiilsus<\/strong><\/strong><\/h3>\n\n\n\n

PLA on madalama kuumastabiilsusega, tavaliselt umbes 150-160 kraadi Celsiuse j\u00e4rgi. See t\u00e4hendab, et k\u00f5rgel temperatuuril v\u00f5ib PLA muutuda pehmeks ja kaotada oma kuju stabiilsuse. Seet\u00f5ttu ei sobi see kasutamiseks k\u00f5rge temperatuuriga keskkondades v\u00f5i kuumakindlust n\u00f5udvates rakendustes.<\/p>\n\n\n\n

Brittleness<\/strong><\/strong><\/h3>\n\n\n\n

PLA on suhteliselt rabe, eriti madalatel temperatuuridel. See muudab selle m\u00f5nes rakenduses v\u00f5rreldes teiste plastidega potentsiaalselt v\u00e4hem vastupidavaks, eriti k\u00fclmades ilmastikutingimustes.<\/p>\n\n\n\n

Bioloogilise lagunemise kiirus<\/strong><\/strong><\/h3>\n\n\n\n

Kuigi PLA v\u00f5ib laguneda, m\u00f5jutavad selle lagunemise kiirust tegelikus keskkonnas erinevad tegurid, sealhulgas temperatuur, niiskus ja mikroorganismide olemasolu. M\u00f5nes keskkonnas v\u00f5ib PLA lagunemiskiirus olla suhteliselt aeglane, mis toob kaasa v\u00f5imalikud keskkonnaj\u00e4\u00e4gid.<\/p>\n\n\n\n

Raskused ringlussev\u00f5tmisel<\/strong><\/strong><\/h3>\n\n\n\n

Hoolimata sellest, et PLA on biolagunev materjal, on selle tegeliku ringlussev\u00f5tu k\u00e4igus keeruline seda eraldada, kui see seguneb teiste plastidega. See teeb PLA materjalide ringlussev\u00f5tu keeruliseks.<\/p>\n\n\n\n

\"pla<\/figure>\n\n\n\n

Toidupakendid<\/strong><\/strong><\/h3>\n\n\n\n

PLA mittetoksiline ja biolagunev olemus muudab selle ideaalseks valikuks toiduainete pakendamiseks. PLA-materjalist saab valmistada \u00fchekordselt kasutatavaid tasse, kausse ja muid tarbeesemeid.<\/p>\n\n\n\n

Kosmeetika<\/strong> Pakend<\/strong><\/strong><\/h3>\n\n\n\n

PLA, mille l\u00e4bipaistvus, l\u00e4ikivus ja vormitavus on suurep\u00e4rased, sobib h\u00e4sti kosmeetikapakendite valmistamiseks.<\/p>\n\n\n\n

3D printimine<\/strong><\/strong><\/h3>\n\n\n\n

Due to its low melting point, ease of processing, and non-toxic nature, PLA is widely used in the field of 3D printing. It doesn’t emit toxic gases when heated, making it a popular choice.<\/p>\n\n\n\n

Tekstiilit\u00f6\u00f6stus<\/strong><\/strong><\/h3>\n\n\n\n

PLA-st valmistatud kiudusid saab kasutada tekstiilit\u00f6\u00f6stuses biop\u00f5histe kangaste tootmiseks. Selle materjali kasutamine aitab v\u00e4hendada s\u00f5ltuvust traditsioonilistest s\u00fcnteetilistest kiududest ja v\u00e4hendab n\u00f5udlust nafta j\u00e4rele.<\/p>\n\n\n\n

Meditsiiniseadmed<\/strong><\/strong><\/h3>\n\n\n\n

T\u00e4nu oma bioloogilisele sobivusele, biolagunevusele ja mitmek\u00fclgsusele kasutatakse PLA-d meditsiiniliste implantaatide ja seadmete valmistamisel. Rakenduste hulka kuuluvad ortopeedilised implantaadid, \u00f5mblusmaterjalid ja tellingud.<\/p>\n\n\n\n

Protot\u00fc\u00fcpimine<\/strong><\/strong><\/h3>\n\n\n\n

T\u00e4nu oma lihtsale t\u00f6\u00f6tlemisele, kuluefektiivsusele ja suurep\u00e4rasele tulemuslikkusele 3D-printimisel kasutatakse PLA-d tavaliselt protot\u00fc\u00fcpide valmistamisel. Protot\u00fc\u00fcpide valmistamine PLAga 3D-printimise abil v\u00f5ib t\u00f5husalt v\u00e4hendada katse-eksituse kulusid enne teatud toodete masstootmisele \u00fcleminekut.<\/p>\n\n\n\n

PLA l\u00f5pliku k\u00f5rvaldamise meetodid<\/strong><\/h2>\n\n\n\n
\"pla<\/figure>\n\n\n\n

Taaskasutamine<\/strong><\/strong><\/h3>\n\n\n\n

PLA-materjale saab ringlusse v\u00f5tta ja ringlusse v\u00f5etud PLA-d saab kasutada uute PLA-materjalide tootmiseks, v\u00e4hendades n\u00f5udlust tooraine j\u00e4rele.<\/p>\n\n\n\n

Kompostimine<\/strong><\/strong><\/h3>\n\n\n\n

T\u00f6\u00f6stuslikus kompostimiskeskkonnas v\u00f5ib PLA materjal laguneda veeks ja s\u00fcsihappegaasiks, j\u00e4tmata kahjulikke j\u00e4\u00e4ke.<\/p>\n\n\n\n

P\u00f5letamine<\/strong><\/strong><\/h3>\n\n\n\n

PLA-materjale saab t\u00f6\u00f6delda ka p\u00f5letamise teel. PLA p\u00f5letamise k\u00f5rvalsaadusteks on vesi ja s\u00fcsinikdioksiid, mist\u00f5ttu on see keskkonnas\u00f5bralik. P\u00f5letusprotsess peaks siiski toimuma spetsiaalsetes p\u00f5letusrajatistes.<\/p>\n\n\n\n

Pr\u00fcgila<\/strong><\/strong><\/h3>\n\n\n\n

Pr\u00fcgilasse ladestamine ei ole PLA jaoks k\u00f5ige ideaalsem k\u00f5rvaldamismeetod. Traditsioonilistes pr\u00fcgilates, kus puudub hapnik ja sobiv niiskus, ei pruugi PLA t\u00f5husalt laguneda, mist\u00f5ttu see koguneb pinnasesse.<\/p>\n\n\n\n

PLA tulevik<\/strong><\/strong><\/h2>\n\n\n\n

PLA tulevane areng pakub palju paljut\u00f5otavaid suundi.<\/p>\n\n\n\n

Bioloogilise lagunevuse suurendamine<\/strong><\/strong><\/h3>\n\n\n\n

One of the primary reasons for using PLA materials is their environmental friendliness. However, there is significant room for improvement in PLA’s biodegradability. In the future, advancements in PLA’s molecular structure and the addition of biodegradation enhancers could enhance its overall biodegradability.<\/p>\n\n\n\n

Kuumuse stabiilsuse ja vastupidavuse parandamine<\/strong><\/strong><\/h3>\n\n\n\n

PLA currently exhibits relatively low heat stability and toughness. Future advancements can involve employing new production processes and using novel additives to enhance PLA’s heat stability and toughness. This would broaden its applications across various industries.<\/p>\n\n\n\n

Ringlussev\u00f5tu meetodite t\u00e4iustamine<\/strong><\/strong><\/h3>\n\n\n\n

PLA praegune ringlussev\u00f5tt on keeruline, peamiselt seet\u00f5ttu, et seda on ringlussev\u00f5tu k\u00e4igus raske eristada tavalistest plastidest. Ringlussev\u00f5tuprotsesside ja -meetodite edasine t\u00e4iustamine v\u00f5ib aidata v\u00e4hendada n\u00f5udlust PLA tooraine j\u00e4rele, suurendades seel\u00e4bi ressursit\u00f5husust.<\/p>\n\n\n\n

Tootmiskulude v\u00e4hendamine<\/strong><\/strong><\/h3>\n\n\n\n

The current production cost of PLA is relatively high. As more factories engage in PLA production, technological innovations are expected to bring about cost reductions, enhancing PLA’s competitiveness.<\/p>\n\n\n\n

Biop\u00f5histe toorainete mitmekesisuse suurendamine<\/strong><\/strong><\/h3>\n\n\n\n

PLA tootmiseks on praegu suhteliselt v\u00e4he tooraineid, millest k\u00f5ige sagedamini kasutatakse maisit\u00e4rklist. See tekitab muret m\u00f5ju p\u00e4rast maisile kui olulisele toiduvarule. Tulevikus v\u00f5iks seda probleemi t\u00f5husalt lahendada j\u00f5upingutused PLA tootmiseks laiemast taimevalikust kulutasuval viisil.<\/p>\n\n\n\n

PLA omaduste parandamise strateegiad<\/strong><\/strong><\/h3>\n\n\n\n

Plastifitseerimine<\/strong><\/strong><\/h4>\n\n\n\n

The use of suitable plasticizers can enhance the flexibility and processability of PLA. Common plasticizers include plasticizing agents and toughening agents. Plasticizing agents improve the plasticity of PLA, reduce its glass transition temperature, thereby enhancing flexibility. Toughening agents increase PLA’s toughness, making it more impact-resistant and slowing down crack propagation.<\/p>\n\n\n\n

Mineraalsed t\u00e4iteained<\/strong><\/strong><\/h4>\n\n\n\n

Introducing mineral fillers such as nanoparticles and fibers can increase PLA’s hardness, strength, and wear resistance. Mineral fillers enhance PLA’s structure at the molecular level, improving its mechanical properties.<\/p>\n\n\n\n

M\u00f5ju modifikaatorid<\/strong><\/strong><\/h4>\n\n\n\n

Incorporating impact modifiers like modified polymers or elastomers can enhance PLA’s impact resistance. Impact modifiers absorb impact energy, preventing crack propagation and improving PLA’s impact resistance.<\/p>\n\n\n\n

Pol\u00fcmeeride segamine<\/strong><\/strong><\/h4>\n\n\n\n

PLA segamine teiste sobivate pol\u00fcmeeridega v\u00f5imaldab kohandada erinevaid omadusi, n\u00e4iteks parandada termilist stabiilsust ja suurendada mehaanilisi omadusi.<\/p>\n\n\n\n

PLA is commonly referred to as “Corn Plastic” because one of its primary raw materials is extracted from corn starch.<\/p>\n\n\n\n

Millised on PLA alternatiivid?<\/strong><\/h3>\n\n\n\n

PLA asendamiseks on mitmeid alternatiive, millel k\u00f5igil on oma eelised ja puudused konkreetsete rakenduste ja j\u00f5udlusn\u00f5uete puhul. Siin on m\u00f5ned levinud alternatiivid PLA-le:<\/p>\n\n\n\n

Pol\u00fcet\u00fcleen<\/strong><\/strong><\/h4>\n\n\n\n

T\u00fc\u00fcbid: LDPE (LDPE), lineaarne madala tihedusega pol\u00fcet\u00fcleen (LLDPE) jne.<\/p>\n\n\n\n

Omadused: Pol\u00fcet\u00fcleen on tavaline naftap\u00f5hine plast, millel on hea keemiline vastupidavus, kulumiskindlus ja elektriisolatsioon. Sellel puudub aga PLA biolagunevus.<\/p>\n\n\n\n

Pol\u00fcprop\u00fcleenist<\/strong><\/strong><\/h4>\n\n\n\n

Omadused: Pol\u00fcprop\u00fcleen on teine levinud plast, millel on k\u00f5rgem sulamistemperatuur ja t\u00f5mbetugevus. See on PLAga v\u00f5rreldes v\u00e4hem biolagunev, kuid v\u00f5ib olla sobivam konkreetsete rakenduste jaoks.<\/p>\n\n\n\n

Pol\u00fcvin\u00fc\u00fclkloriid (PVC)<\/strong><\/strong><\/h4>\n\n\n\n

Omadused: PVC on mitmek\u00fclgne plastik, mida kasutatakse laialdaselt ehitus-, meditsiini- ja pakendit\u00f6\u00f6stuses. PVC tootmine ja k\u00f5rvaldamine v\u00f5ib siiski kaasa tuua m\u00fcrgiste gaaside eraldumise, mis tekitab keskkonna- ja terviseprobleeme.<\/p>\n\n\n\n

Bioplastid<\/strong><\/strong><\/h4>\n\n\n\n

T\u00fc\u00fcbid: Lisaks PLA-le on olemas ka teisi bioplastid, nagu pol\u00fcet\u00fcleenfuranaat (PEF), pol\u00fch\u00fcdroks\u00fcalkanoaadid (PHA) jne.<\/p>\n\n\n\n

Omadused: Need plastid p\u00f5hinevad tavaliselt osaliselt v\u00f5i t\u00e4ielikult biomassil, pakkudes taastuvaid ja biolagunevaid omadusi. Nad v\u00f5ivad olla teatud rakendustes PLA alternatiiviks.<\/p>\n\n\n\n

Omadused: PEEK on suure j\u00f5udlusega tehniline plast, millel on suurep\u00e4rased kuumakindlus, keemiline stabiilsus ja mehaanilised omadused. See sobib n\u00f5udlikeks t\u00f6\u00f6stuslikeks rakendusteks, kuid ei ole biolagunev nagu PLA.<\/p>\n\n\n\n

Omadused: Need plastid on tavaliselt t\u00e4rklise ja teiste pol\u00fcmeeride segu, mis pakub biolagunevust. Siiski v\u00f5ib nende toimivust m\u00f5jutada tundlikkus niiskuse suhtes ja halb kuumakindlus.<\/p>\n\n\n\n
