Xov xwm

Cov ntaub ntawv degradable yog ib chav kawm ntawm cov ntaub ntawv polymer uas tuaj yeem decomposed rau hauv cov khoom tsis muaj teeb meem los ntawm kev ua microbial hauv ib puag ncig ntuj, uas yog qhov tseem ceeb hauv kev txo cov pa phem thiab tiv thaiv ib puag ncig. Hauv qab no yog cov ntsiab lus ntawm ntau yam khoom siv biodegradable:

1. PLA (polylactic acid):

Ua los ntawm cov khoom siv cog dua tshiab (xws li pob kws hmoov nplej), nws yog cov yas biodegradable.

Nws muaj cov khoom siv zoo, thermal stability thiab tshuaj tiv thaiv, thiab tuaj yeem ua rau hauv cov khoom los ntawm ntau yam txheej txheem xws li txhaj tshuaj molding, extrusion thiab tshuab moulding.

Cov ntawv thov suav nrog kev lag luam ntim khoom, kev lag luam textile, kev kho mob, kev ua liaj ua teb thiab kev lag luam tsheb.

2.PBAT (polybutylene terephthalate / adipic acid):

Nws yog tag nrho biodegradable yas nrog cov yam ntxwv ntawm PBA thiab PBT, zoo mechanical zog thiab biodegradability.

Nws yog tsuas yog siv nyob rau hauv lub khw muag khoom lub hnab, nqa tawm lub thawv noj su, ua liaj ua teb zaj duab xis, thiab lwm yam, nrog rau kev lag luam muaj zog.

3. PCL (polycaprolactone):

Nws yog ib tug polymer nrog zoo heev biocompatibility thiab degradability.

PCL tau dav siv hauv kev kho mob vim nws cov ductility ntau dua thiab zoo heev biocompatibility.

Txoj kev loj hlob ntawm kev lag luam plastics degradable ntsib ntau yam teeb meem, xws li cov nqi siab, kev txwv kev siv tshuab, kev ua cov teeb meem thiab cov chaw kho mob tsis txaus. Txawm li cas los xij, nrog kev txhim kho thev naus laus zis thiab kev txhawb nqa txoj cai, cov yas degradable yuav tsum tau siv ntau dua yav tom ntej.

Cov teeb meem uas yuav raug ntsib thaum ua cov ntaub ntawv degradable xws li PLA, PBAT, thiab lwm yam, suav nrog:

1. Tsis txaus toughness thiab ductility: Piv txwv li, txawm hais tias PLA muaj cov khoom siv zoo, nws lub zog tsis zoo thiab nws cov crystallization qeeb, uas txwv tsis pub siv cov khoom siv hauv engineering plastics.

2. Qhov rai ua haujlwm nqaim: Qee cov ntaub ntawv degradable xws li PLA muaj qhov tsis zoo thermal stability thiab nqaim qhov rais, uas yuav ua rau muaj teeb meem hauv kev ua haujlwm.

3. Melt fluidity teeb meem: Nyob rau hauv kev ua cov ntaub ntawv degradable xws li PBAT thiab PLA, lub yaj siab yog loj heev vim lub viscosity ntau dhau ntawm cov yaj, uas yog ib qho yooj yim los tsim pwm expansion thiab nag lossis daus, thaum cuam tshuam rau kev ua fluidity thiab txo cov efficiency ntau lawm.

Txhawm rau txhim kho cov txheej txheem lubrication, cov teeb meem no tuaj yeem daws tau los ntawm kev ntxiv cov txheej txheem AIDS, xws li:SILIKE SILIMER DP800, SILIKE SILIMER DP800yog ib qho kev pab cuam tsim tshwj xeeb rau cov ntaub ntawv degradable, uas tuaj yeem txhim kho kev ua haujlwm zoo thiab qhov zoo ntawm cov khoom degradable.

SILIKE SILIMER DP800, high kev ua haujlwm AIDS tshwj xeeb tsim rau PLA, PCL, PBAT thiab lwm yam khoom siv degradable.

SILIKE SILIMER DP800yog ib qho kev hloov kho silicone additive nrog cov nram qab no zoo zoo rau cov ntaub ntawv degradable:

Cov khoom ua haujlwm:

Txhim kho qhov sib haum xeeb ntawm cov khoom siv hmoov thiab cov khoom siv substrate, txhim kho kev ua haujlwm ntawm cov khoom, thiab muaj cov roj lubrication zoo. Nws tuaj yeem txo cov viscosity yaj, txo cov extruder torque, extrusion siab, txhim kho kev ua haujlwm ntawm cov khoom, thiab muaj kev ua haujlwm zoo lubrication.

Surface Properties:

Txhim kho khawb tsis kam thiab hnav tsis kam, txo qhov kev sib txhuam coefficient, tuaj yeem txhim kho qhov zoo ntawm cov khoom, nrog rau qee yam smoothness.

Lwm yam khoom:

Ua haujlwm zoo tswj cov khoom siv kho tshuab dav dav ntawm cov khoom, tsis cuam tshuam rau cov yam ntxwv degradable ntawm cov khoom.

Qhov tseem ceeb ntawm cov ntaub ntawv degradable yog los txo cov pa phem ib puag ncig, txo kev siv hluav taws xob, thiab muab cov kev daws teeb meem ruaj khov. Biodegradable cov ntaub ntawv tuaj yeem tsis tsuas yog txo qhov cuam tshuam ntawm cov khoom pov tseg ntawm ib puag ncig, tab sis kuj muaj kev lag luam loj thiab muaj peev xwm. Txhim kho cov txheej txheem thiab qhov zoo ntawm cov khoom degradable yog qhov txuas uas tsis tuaj yeem tsis quav ntsej.

Koj puas koom nrog kev tsim khoom thiab tsim cov khoom siv degradable? yog tias cov khoom tsis zoo yog tshwm sim los ntawm kev ua cov ntaub ntawv, nws raug nquahu kom koj simTSEEM CEEB DP800, TSEEM CEEB DP800yog tsim rau PLA, PCL, PBAT thiab lwm yam ntaub ntawv degradable. Nws tuaj yeem siv dav rau degrade films, straws, 3D luam ntawv consumables thiab lwm yam lag luam.
