TusNtev ntawm tus txheej txheem tom qab raug khoRau silicone roj hmab nyob ntawm ntau yam uas cuam tshuam zoo npaum li cas cov khoom ua tiav, tshuaj lom neeg, thiab cov khoom thermal. Hauv qab no yog cov ntsiab lus tseem ceeb:
1. Cov Khoom Siv Khoom Siv
Silicone Hom:
Cov qhab nees sib txawv ntawm silicone (piv txwv li, kho mob, khoom noj-qib, muaj kev lag luam sib txawv.
Kev nrawm nrawm kawm qib: Xav tau lub sijhawm rov kho dua tshiab.
Cov Silica Tshwj Xeeb: High-purity lossis kev tswj hwm-ua raws silicones yuav xav tau ncua ntev kom tshem tawm cov roj tawg.
Hla kev nrawm:
Tus nqi ntawm crosslinking (kho) sib txawv raws li cov qauv cua (platinum catalalyst txheej txheem.
Tus yam ntxwv: Ib txwm muaj siab turity lsr yuav xav tau2-4 teev, whereas lub siab-ua haujlwm Industrial-qib silicone yuav xav tau tsawg lub sijhawm.
2. Kub
Ua kom muaj kev kub siab dua ua kom nrawm dua, txo lub sijhawm uas yuav tsum tau, thaum txo qis dua nws qeeb.
Cov Qauv Kev Sib Raug:
Ntawm200℃(392℃f): Post-cathing feem ntau yuav siv2-4 teev.
Ntawm150℃(302℃f): Tsib Hlis 6-8 teev lossis ntev dua.
Ntawm250℃(482℃f): Cov txheej txheem tuaj yeem ua tiav hauv1-2 teev.
Chaw sib pauv-tawm:
Thaum cov sijhawm kub siab txog qhov kub tsawg zaus txo lub sijhawm, lawv tuaj yeem ua rau muaj kev pheej hmoo ntawm cov khoom siv tsis taus, tshwj xeeb rau cov ntawv thov.
3. Part Thickness thiab loj
Thicker Xeem:
Yuav tsum muaj cov sijhawm ntev kom cia cov cua sov kom nkag mus thiab kho cov khoom siv tsis zoo.
CarePlience Tsis Txhuam hauv cov ntu thicker tuaj yeem tawm hauv cov zaub mov tsis muaj zog lossis ua kom huv si silicone.
Nyias lossis me me:
Yuav tsum muaj sijhawm tsawg dua vim tias kub nkag mus sai sai thiab tusyees.
Tus yam ntxwv:
Ib feem nrog a1 hli phab ntsa tuabtej zaum yuav tsum tau1-2 teevNtawm 200 degree.
Ib feem nrog a10 hli tuabyuav siv4-6 teevntawm tib qho kub.
4. Tshem tawm ntawm cov zaub mov
Thaum lub sij hawm kho cov txheej txheem, seem ntawm cov neeg ua haujlwm (piv txwv li, cov roj ntsha uas tsis muaj kev cuam tshuam nrog cov khoom siv.
Yam cuam tshuam rau kev tshem tawm volatile:
Khoom Siv Khoom: Kev kho mob thiab cov khoom noj-qib silicones xav kom ua kom txhua qhov tsis txaus siab tau tshem tawm.
Cub cua: Lub tshuab nqus tsev kom zoo lossis lub tshuab nqus tsev tuaj yeem ua kom tshem tawm cov kev tshem tawm ntawm cov zaub mov.
Tus yam ntxwv:
Kho mob silicone yuav xav tau4 teev ntawm 200 degreeTxhawm rau ntsib cov qauv kev cai ib yam li FDA lossis USP chav kawm VI.
5. Qhov qauv tsim thiab geometry
Cov geometries complex:
Qhov chaw nrog cov nta intricate, undercuts, lossis cov chaw uas muaj chaw (piv txwv li, cov chaw hollow) yuav ntxiab volatiles lossis kub, xav tau lub sijhawm txuas ntxiv.
Kev sib koom:
Cov tsis muaj zog tsis zoo (piv txwv li, nrog sib txawv tuab) siv sijhawm ntev dua los xyuas kom txhua thaj kev kho tau uniformly.
6. Daim ntawv thov-cov kev cai tshwj xeeb
Kev Tswj Fwm:
Cov ntawv thov xws li cov cuab yeej kho mob lossis cov khoom lag luam sib cuag cov khoom noj feem ntau yuav tsum tau kho lub sijhawm ntev ntev kom muaj kev nyab xeeb thiab huv.
Cov Qauv Qauv:
Aerospace thiab cov khoom lag luam yuav xav tau kev kho cov cua sov los txhim kho cov pa thermal lossis cov khoom siv compression compression.
Xa-Kho Kev Tshawb Xyuas:
Qee qhov kev lag luam xav tau kev sim ntxiv (piv txwv li, tshuab lossis tshuaj lom neeg ua haujlwm), uas yuav hais kom them lub sijhawm ntev dua los ua kom tau raws li cov lus qhia.
7. Cub hom thiab efficiency
Thaum Tshav Kub Kub Hloov Efficiency:
Convection ncu nrog cov uniform airflow thiab zoo ib yam kub kho sai dua tsawg dua li tsawg dua ua ncu.
Lub tshuab nqus tsev:
Lub Tshuab Nqus Tsev Ncauj tuaj yeem txo lub sijhawm kho los ntawm ib lub sijhawm tshem tawm cov neeg hloov pauv thiab hloov tshav kub hauv qis qis.
Batch Vs. Nruam Ua Ntej:
Qhov chaw lossis lub ncu txuas ntxiv yuav muaj cov sijhawm sib txawv nyob ntawm cov chaw ua haujlwm ceev thiab txias thiab txias.
8. Thawj zaug kho hauv cov pwm
Qhov uas cov Silicone tau kho thaum lub sijhawm txhaj tshuaj molding cov txheej txheem cuam tshuam rau lub sijhawm rov qab.
Ib nrab kho cov khoom:
Yuav tsum tau ntev dua tom qab kho dua tshiab kom tiav crosslinking.
Tag nrho kho qhov chaw:
Tej zaum tsuas yog yuav tsum tau ua luv luv-kho cov kauj ruam los tshem tawm cov khoom noj.
9. Cov hom phiaj
Neeg kho tshuab li:
Ntev ntev durations txhim kho lub zog tensile, lub kua muag tiv, thiab nias twj teeb.
Thermal ruaj khov:
Thaum tshav kub kub ua kom tau thiab ntev ntev ua tau zoo dua nrog kev kho tom qab.
Tshuaj Kuj:
Kev Kho Kom Ncua Txhim Kho Kom Ua Kom Tau Roj Av, cov kuab tshuaj, thiab ib puag ncig cov xwm txheej.

Lub ntsiab
Lub sijhawm ntawm tom qab raug kho nyob ntawm:
Cov Khoom Siv Qib thiab Daim Qauv(crosslinking ceev, volatiles).
Qho so(Ntau dua temp=lub sijhawm luv dua).
Ntu Thickness Thiab Geometry(thicker / complex=ntev lub sijhawm).
Daim ntawv thov-cov kev xav tau tshwj xeeb(kev cai tswjfwm lossis ua haujlwm hom phiaj).
Cov Khoom Siv Efficievy(Cub yam thiab airflow).
Los ntawm kev ntsuas cov xwm txheej no, koj tuaj yeem ua kom zoo dua cov txheej txheem tom qab kev kho kom ua tiav cov khoom xav tau thaum muaj zog thiab sijhawm.
