Cov khoom siv uas lwj tau yog ib pawg ntawm cov khoom siv polymer uas tuaj yeem lwj mus ua cov khoom tsis muaj teeb meem los ntawm kev ua haujlwm ntawm cov kab mob hauv ib puag ncig ntuj, uas yog qhov tseem ceeb heev rau kev txo cov yas ua qias tuaj thiab tiv thaiv ib puag ncig. Hauv qab no yog cov ntsiab lus ntawm ntau cov khoom siv uas lwj tau:

1. PLA (polylactic acid):

Ua los ntawm cov khoom siv cog qoob loo uas rov ua dua tshiab (xws li hmoov pob kws), nws yog cov yas uas lwj tau.

Nws muaj cov khoom siv kho tshuab zoo, thermal stability thiab tshuaj lom neeg tsis kam, thiab tuaj yeem ua rau cov khoom los ntawm ntau yam txheej txheem xws li kev txhaj tshuaj molding, extrusion thiab tshuab molding.

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 ib lub yas uas lwj tag nrho nrog cov yam ntxwv ntawm PBA thiab PBT, cov khoom siv kho tshuab zoo thiab biodegradability.

Nws yog siv rau hauv cov hnab khw loj, cov thawv noj su, cov yeeb yaj kiab av ua liaj ua teb, thiab lwm yam, nrog rau kev thov ua lag luam muaj zog.

3. PCL (polycaprolactone):

Nws yog ib qho polymer uas muaj biocompatibility zoo heev thiab degradability.

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

Kev txhim kho ntawm kev lag luam yas uas lwj tau ntsib ntau yam teeb meem, xws li tus nqi siab, kev txwv ntawm thev naus laus zis, teeb meem ua khoom thiab tsis txaus cov chaw kho mob tom qab. Txawm li cas los xij, nrog kev nce qib ntawm thev naus laus zis thiab kev txhawb nqa txoj cai, cov yas uas lwj tau xav tias yuav siv dav dua yav tom ntej.

Cov teeb meem uas yuav ntsib thaum ua cov khoom siv lwj xws li PLA, PBAT, thiab lwm yam, suav nrog:

1. Tsis txaus toughness thiab ductilityPiv txwv li, txawm hais tias PLA muaj cov khoom siv kho tshuab zoo, nws qhov tawv tsis zoo thiab nws cov nqi crystallization qeeb, uas txwv nws txoj kev siv hauv kev siv plastics engineering.

2. Qhov rai ua haujlwm nqaimQee cov ntaub ntawv uas lwj tau xws li PLA muaj kev ruaj khov thermal tsis zoo thiab lub qhov rais ua haujlwm nqaim, uas yuav ua rau muaj teeb meem hauv cov txheej txheem ua haujlwm.

3. Teeb meem ntawm cov kua yaj: Hauv kev ua cov khoom siv lwj xws li PBAT thiab PLA, qhov siab yaj loj dhau vim yog qhov viscosity ntau dhau ntawm cov yaj, uas yooj yim tsim cov pwm nthuav dav thiab nag, thaum cuam tshuam rau kev ua haujlwm fluidity thiab txo cov txiaj ntsig ntau lawm.

Yuav kom txhim kho qhov ua kom lubricity ntawm cov khoom siv, cov teeb meem no tuaj yeem daws tau los ntawm kev ntxiv cov khoom siv pab txhawb kev ua haujlwm, xws li:SILIKE SILIMER DP800, SILIKE SILIMER DP800yog ib qho khoom pab ua cov khoom uas tsim tshwj xeeb rau cov khoom uas lwj tau, uas tuaj yeem txhim kho cov txheej txheem ua khoom thiab qhov zoo ntawm cov khoom uas lwj tau.

SILIKE SILIMER DP800, hCov cuab yeej pab ua haujlwm siab tsim tshwj xeeb rau PLA, PCL, PBAT thiab lwm yam khoom siv uas lwj tau.

SILIKE SILIMER DP800yog ib qho khoom siv silicone hloov kho nrog cov txiaj ntsig zoo li nram no rau cov ntaub ntawv lwj:

Cov khoom ua tiav:

Txhim kho qhov sib xws ntawm cov khoom siv hmoov thiab cov khoom siv substrate, txhim kho cov txheej txheem ua haujlwm ntawm cov khoom, thiab muaj kev ua haujlwm zoo ntawm lubrication. Nws tuaj yeem txo cov viscosity ntawm yaj, txo cov extruder torque, extrusion pressure, txhim kho kev ua haujlwm ntawm cov khoom, thiab muaj cov roj nplua nyeem zoo.

Cov khoom nto:

Txhim kho qhov khawb tsis kam thiab hnav tsis kam, txo qhov sib txhuam ntawm qhov chaw, tuaj yeem txhim kho qhov kev xav ntawm cov khoom, nrog rau qee qhov du.

Lwm yam khoom:

Ua kom zoo tswj cov khoom siv kho tshuab ntawm cov khoom, yam tsis cuam tshuam rau cov yam ntxwv ntawm cov khoom lwj.

Qhov tseem ceeb ntawm cov khoom siv uas lwj tau yog kom txo tau kev ua qias tuaj rau ib puag ncig, txo kev siv hluav taws xob, thiab muab cov kev daws teeb meem uas ruaj khov. Cov khoom siv uas lwj tau tsis yog tsuas yog txo tau qhov cuam tshuam ntawm cov yas pov tseg rau ib puag ncig xwb, tab sis kuj muaj kev cia siab loj heev rau kev ua lag luam thiab muaj peev xwm. Kev txhim kho qhov ua tau zoo thiab qhov zoo ntawm cov khoom siv uas lwj tau yog ib qho txuas uas tsis tuaj yeem tsis quav ntsej.

Koj puas koom nrog kev tsim khoom thiab tsim cov khoom siv uas lwj tau? Yog tias qhov tsis zoo ntawm cov khoom yog los ntawm kev ua cov khoom siv, nws raug pom zoo kom koj simSILIMER DP800, SILIMER DP800yog tsim rau PLA, PCL, PBAT thiab lwm yam khoom siv uas lwj tau. Nws tuaj yeem siv dav los rhuav cov yeeb yaj kiab, cov straw, cov khoom siv luam ntawv 3D thiab lwm yam lag luam.
