PLA muaj cov thermal stability zoo, ua haujlwm kub ntawm 170-230 degree, hnyav hnyav, thiab tuaj yeem ua tiav ntau txoj hauv kev, xws li extrusion, spinning, biaxial stretching, txhaj tshuaj molding. Cov khoom tsim los ntawm polylactic acid tsis tsuas yog muaj biodegradability, tab sis kuj muaj biocompatibility zoo, glossiness, pob tshab, tes xav, thiab kub tsis kam. Lawv kuj muaj qee yam kab mob tiv thaiv, nplaim hluav taws, thiab UV tsis kam. Yog li ntawd, lawv tau dav siv los ua cov khoom ntim, fibers, thiab cov ntaub tsis-woven. Tam sim no, lawv feem ntau yog siv rau hauv kev lag luam xws li khaub ncaws (cov ris tsho hauv qab, cov ris tsho sab nrauv), kev lag luam (tsim, kev ua liaj ua teb, hav zoov, papermaking), thiab kev kho mob.
01
Biomedical teb
Hauv kev lag luam biomedicine, cov ntaub ntawv polylactic acid tuaj yeem siv los ua cov khoom thauj tshuaj, cov ntaub so ntswg engineering scaffold, cov ntaub ntawv kho pob txha, thiab lwm yam.
Kev kho mob yog ib qho kev siv thaum ntxov ntawm PLA thiab nws cov khoom sib xyaw. Tam sim no, nws tau ua tiav kev tshawb fawb dav dav thiab kev siv tshuaj kho mob hauv kev phais orthopedic, phais thoracic, phais maxillofacial, qog tsom rau kev kho mob thiab lwm yam.
02
Kev lag luam thiab kev ua liaj ua teb
PLA muaj cov yas zoo, tiv thaiv tshav kub, thiab ua haujlwm lub cev. Nws tuaj yeem ua tiav rau hauv zaj duab xis ua liaj ua teb kom them nyiaj rau qhov fragility thiab tsis degradability ntawm cov yeeb yaj kiab ib txwm muaj. Nws kuj tseem tuaj yeem ua tiav rau hauv cov khoom siv engineering rau kev lag luam tsheb, kev tsim cov hlua, tshuaj tua kab thiab cov ntaub ntawv tso tawm qeeb, thiab lwm yam.
03
Cov khoom ntim khoom noj
Piv nrog rau cov ntaub ntawv xws li polyethylene (PE), polyvinyl chloride (PVC), thiab polypropylene (PP), polylactic acid (PLA) muaj biodegradability zoo, zoo heev antibacterial thiab antifungal zog.
POTOP ® Multilayer Coextrusion Casting Production Line tuaj yeem siv los kuaj thiab ua ntau yam ntaub ntawv xws li yas thiab elastomers, thiab txiav txim siab thiab ntsuas cov cim tseem ceeb xws li yaj siab thiab kub thaum lub sij hawm extrusion txheej txheem. Cov khoom siv hluav taws xob thiab cov ntsia hlau lub taub hau ntawm extruder yog txhua yam ua los ntawm cov khoom lag luam paub zoo hauv tsev thiab txawv teb chaws, thiab txhua tus extruder yog nruab nrog kev tiv thaiv npog los txhim kho kev ua haujlwm kev nyab xeeb; Lub tshuab auxiliary casting txais yuav kab rov tav layout rau kev ua haujlwm yooj yim. Txhua lub servo lub cev muaj zog yog tsav ntawm nws tus kheej, thiab lub rooj zaum ntawm cov menyuam yog coj los ntawm cov kab zawv zawg. Muaj cov cuab yeej hloov kho kom zoo kom ntseeg tau qhov tuab thiab qhov tseeb ntawm zaj duab xis.
