Cov ntaub ntawv degradable yog chav kawm ntawm cov ntaub ntawv polymer uas tuaj yeem decomposed rau hauv cov tshuaj phem hauv kev ua qias tuaj thiab tiv thaiv ib puag ncig. Hauv qab no yog cov ntsiab lus ntawm ntau hom khoom biodegradable:
1. PLA (polylactic acid):
Ua los ntawm cov khoom siv cog tauj dua tshiab (xws li pob kws cov hmoov txhuv nplej siab), nws yog cov hnab yas biodegradable.
Nws muaj cov kws kho tshuab zoo, thermal ruaj khov thiab tshuaj lom neeg kuj, thiab tuaj yeem ua rau cov khoom lag luam xws li kev txhaj tshuaj molding, extrusion thiab tshuab moulding.
Cov ntawv thov suav nrog kev lag luam ntim, kev lag luam textile, kev kho mob teb, kev lag luam kev ua liaj ua teb thiab kev lag luam automotive.
2.pbat (polybutylene terephthalate / adipic acid):
Nws yog cov khoom siv biodegradable tag nrho nrog cov yam ntxwv ntawm PBA thiab PBT, cov kws kho tshuab zoo thiab cov khoom siv biodegradability.
Nws yog tsuas yog siv nyob rau hauv cov hnab ntim khoom lag luam, noj su - cov duab ua liaj ua teb ua liaj ua teb, thiab lwm yam, nrog muaj zog lag luam xav tau.
3. PCL (Polycaprolactone):
Nws yog lub polymer nrog zoo biocompatibility thiab kev tsis taus.
PCL yog dav siv nyob rau hauv kev kho mob teb vim nws qhov kev sib txawv ntau dua thiab kev ua tau zoo biocompatibility.
Kev txhim kho ntawm cov kev lag luam ruaj khov kho cov kev sib tw, xws li cov nqi siab, ua cov teeb meem thev naus laus zis thiab ua tsis tau zoo cov chaw kho mob. Txawm li cas los xij, nrog kev nce qib thev naus laus zis thiab txoj cai txhawb nqa, qhov tsis txaus ntseeg tau yuav tsum tau siv dua tshiab rau yav tom ntej.
Cov teeb meem uas yuav ntsib thaum ua cov ntaub ntawv degradable xws li PLA, PBAT, thiab lwm yam, suav nrog:
1. Tsis txaus thiab ductility: Piv txwv li, txawm hais tias pla muaj cov khoom siv zoo, nws qhov tsis zoo yog qhov tsis zoo thiab qeeb, uas txo tau hauv kev siv tshuab plastics.
2. Nqaim Ua Si Qhov rai: Qee cov ntaub ntawv degradable xws li PL muaj tsis muaj kev txom nyem thermal stability thiab cov nqaim ua rau kev nyuaj hauv kev ua tiav.
3. Cov teeb meem muaj teeb meem: Hauv kev ua cov ntaub ntawv tsis sib xws xws li PBAT thiab PLA, cov neeg muaj kuab heev los tsim cov pwm thiab dej nag ntau dhau, thaum cuam tshuam rau kev ua kom haum rau kom muaj kev ua tau zoo.
Txhawm rau txhim kho lubrice ua, cov teeb meem no tuaj yeem daws los ntawm kev ntxiv cov AIDS AIDS, xws li:Silike silimer dp800, Silike silimer dp800yog cov kev pab ua tsim tshwj xeeb rau cov khoom siv tsis tau, uas tuaj yeem txhim kho kev ua cov dej ntws thiab cov nplaim hluav taws xob zoo ntawm cov khoom siv degradable.
Silike silimer dp800, huve ua tau kev pab tshwj xeeb tsim rau PLA, PCCL, PBAT thiab lwm cov ntaub ntawv degradable.
Silike silimer dp800yog hloov kho silicone additive nrog cov txiaj ntsig zoo hauv qab no rau cov khoom siv degradable:
Khoom:
Txhim kho qhov sib xyaw ntawm hmoov ib txwm thiab substrate, txhim kho kev ua cov dej ntws tsawg, thiab muaj txiaj ntsig lubrication kev ua haujlwm. Nws tuaj yeem txo cov latural viscosity, txo cov extruder torque, txhim kho kev ua haujlwm ntawm cov khoom siv, thiab muaj covricity zoo.
Cov Khoom Nto:
Txhim kho Diginance thiab coj kev tiv thaiv, txo cov coeffication coefficient, tuaj yeem txhim kho lub npoo uas xav tau zoo.
Lwm cov khoom:
Ua tau zoo tswj cov khoom siv kho tshiab ntawm cov khoom lag luam, tsis muaj kev cuam tshuam rau cov yam ntxwv tsis ncaj ntawm cov khoom lag luam.
Qhov tseem ceeb ntawm cov khoom siv degradable yog los txo cov pa phem ib puag ncig, txo kev siv hluav taws xob, thiab muab cov kev daws teeb meem kev ua kom muaj zog. Cov ntaub ntawv biodegradable tsis tuaj yeem txo qis kev cuam tshuam ntawm cov pov tseg ntawm cov pov tseg plastics ntawm ib puag ncig, tab sis kuj tseem ua lag luam kev lag luam thiab peev xwm. Txhim kho cov txheej txheem thiab qhov zoo ntawm cov khoom siv degradable yog qhov txuas uas tsis tuaj yeem tsis quav ntsej.
Puas yog koj koom nrog kev tsim khoom thiab tsim cov khoom siv degradable? Yog tias cov khoom lag luam tsis xws luag yog tshwm sim los ntawm kev ua cov ntaub ntawv, nws raug nquahu kom koj simSilimer dp800, Silimer dp800yog tsim nyog rau cov pla, pcl, pbat thiab lwm yam khoom siv degradable. Nws tuaj yeem yog qhov dav siv los ua cov yeeb yaj kiab ua rau pom tseeb, cov yeeb nkab, 3D luam tawm customables thiab lwm yam lag luam.
