Vim li cas Demolding Roj Hmab thiaj li nyuaj?
Demolding nyuaj yog ib qho kev sib tw tsis tu ncua hauv kev lag luam roj hmab, feem ntau tshwm sim los ntawm kev sib xyaw ntawm cov khoom siv, txheej txheem, thiab cov khoom siv cuam tshuam. Cov kev cov nyom no tsis tsuas yog cuam tshuam kev tsim khoom tab sis kuj cuam tshuam cov khoom zoo. Hauv qab no yog ib qho kev ntsuam xyuas ntawm cov ntsiab lus tseem ceeb.
1. High Adhesion rau Pwm nto
Ua rau: Roj hmab tebchaw, tshwj xeeb tshaj yog cov uas muaj tackiness siab (xws li, roj hmab ntuj los yog tej yam hluavtaws rubbers), tuaj yeem ua raws li cov pwm nto vim yog tshuaj lom neeg los yog qhov nro.
Kev cuam tshuam: Qhov no ua rau kev ua kom ruaj khov, ua rau nws nyuaj rau tso cov khoom tsis muaj kev puas tsuaj.
2. Complex Pwm Geometry
Ua rau: Intricate pwm tsim nrog undercuts, ntse ces kaum, los yog cov kab noj hniav sib sib zog nqus tuaj yeem ntxiab roj hmab, nce kev tiv thaiv thaum demolding.
Kev cuam tshuam: Cov khoom yuav tawg lossis deform thaum raug tshem tawm.
3. Tsis tsim nyogPwm tso tus neeg saib xyuasDaim ntawv thov
Ua rau: Kev siv tsis txaus lossis tsis sib npaug ntawm cov pwm tso tawm cov neeg ua haujlwm, lossis siv tus neeg sawv cev tsis tsim nyog rau cov roj hmab sib xyaw, tuaj yeem txo qis adhesion.
Kev cuam tshuam: Cov txiaj ntsig hauv kev ua raws thiab tsis sib xws demolding.
4. Thermal Expansion thiab Shrinkage
Ua rau: Roj hmab tau txais thermal expansion thaum kho thiab shrinkage thaum txias, uas tuaj yeem ua rau nws tuav cov pwm nruj, tshwj xeeb tshaj yog nyob rau hauv cov pwm nruj.
Kev cuam tshuam: nce kev sib txhuam thiab nyuaj hauv kev tawm.
5. Nto imperfections ntawm Pwm
Ua rau: Rough los yog hnav cov pwm tuaj yeem ua rau muaj kev sib txhuam, thaum cov khoom paug (xws li, roj hmab residue lossis av) tuaj yeem txhim kho adhesion.
Kev cuam tshuam: Cov khoom lo rau pwm, ua rau muaj qhov tsis xws luag lossis puas.
6. Pwm tsim tsis zoo
Ua rau: Pwm tsis muaj lub kaum sab xis tsim nyog lossis ejection mechanisms (xws li, pins lossis cua vents) tuaj yeem cuam tshuam kev tso tawm.
Kev cuam tshuam: Kev siv zog ntau ntxiv lossis kev pheej hmoo ntawm cov khoom puas thaum lub sij hawm demolding.
7. Cov txheej txheem kho cov teeb meem
Ua rau: Over-curing los yog under-kho tuaj yeem hloov cov roj hmab cov khoom nto, ua rau nws nplaum dhau los yog nkig heev.
Kev cuam tshuam: Cov nplaum nplaum ua raws li cov pwm, thaum cov khoom tawg tuaj yeem tawg thaum lub sij hawm demolding.
8. Cov khoom siv cuam tshuam cuam tshuam rau Rubber Demolding
1) Kev sib cuam tshuam ntawm cov khoom siv roj hmab thiab pwm
Cov roj hmab sib txawv sib txawv hauv cov polarity thiab cov qauv tshuaj, cuam tshuam li cas lawv cuam tshuam nrog pwm nto. Piv txwv li, nitrile roj hmab (NBR) muaj cov polar cyano pawg uas zoo li tsim muaj zog lub cev los yog tshuaj tiv thaiv nrog hlau pwm, ua rau kev tso tawm nyuaj. Hloov pauv, fluororubber (FKM), paub txog nws cov tshuaj tiv thaiv zoo heev thiab lub zog qis vim muaj cov fluorine atoms, tseem tuaj yeem pom cov teeb meem pwm adhesion nyob rau hauv qee yam kev ua haujlwm.
2) High Viscosity Ua ntej Vulcanization
Cov roj hmab uas tsis tau kho feem ntau pom muaj viscosity siab, uas ua rau nws tuav nruj nreem rau ntawm qhov chaw pwm thaum molding. Qhov no adhesion intensifies nyob rau hauv siab kub, nce kuj thaum lub sij hawm demolding. Cov roj hmab ntuj, piv txwv li, tshwj xeeb yog viscous thaum ntxov ntawm kev ua, thiab yog tias tsis ua tib zoo tswj, qhov no tuaj yeem ua rau muaj teeb meem loj heev.
3) Kev cuam tshuam ntawm Additives hauv Compound
Formulation additives yog qhov tseem ceeb rau kev ua haujlwm ntawm cov roj hmab, tab sis tuaj yeem ua rau tsis pom kev cuam tshuam. Kev siv cov plasticizers ntau dhau tuaj yeem ua rau cov khoom sib xyaw ua ke ntau dhau, ua rau thaj chaw sib chwv thiab adhesion nrog cov pwm. Hom tsis raug lossis ntau npaum ntawm cov tshuaj tua kab mob tuaj yeem ua rau tsis tiav crosslinking, ua rau cov khoom tsis muaj peev xwm tso tawm kom huv. Tsis tas li ntawd, qee cov khoom siv ntxiv tuaj yeem txav mus rau cov pwm sib cuam tshuam thaum lub sij hawm vulcanization, hloov cov kev sib cuam tshuam ntawm qhov chaw thiab ntxiv kev nyuaj rau demolding.
Cov tswv yim los txhim kho pwm tso tawm thiab ua haujlwm zoo hauv kev ua cov roj hmab
Demolding cov nyom tuaj yeem cuam tshuam rau lub sijhawm voj voog, qhov zoo ntawm qhov chaw, thiab kev tsim khoom tag nrho. Txhawm rau daws cov teeb meem no, SILIKE muab cov ntaub ntawv nthuav dav ntawmsilicone-based additives thiab tso tawm cov neeg sawv cevuas optimize cov txheej txheem demolding rau cov khoom siv roj hmab, piv txwv li, SILIMER 5322.
Txawm hais tias SILIMER 5322 yog Ameslikas tsim los ua cov roj nplua nyeem tshwj xeeb thiab kev pabcuam ua haujlwm rau WPC (Wood-Plastic Composite) daim ntawv thov, kev lag luam tawm tswv yim tau nthuav tawm cov txiaj ntsig tsis xav txog hauv kev ua cov roj hmab ib yam. Roj hmab compounders-tshwj xeeb yog cov neeg ua haujlwm nrog cov roj hmab polar-tau pom tias cov tshuaj ntxiv no ua rau muaj txiaj ntsig zoo rau kev tsim qauv. Nws pab txhim kho dispersion, optimize cov txheej txheem ua, thiab txhim kho tag nrho cov formulation efficiency, ua rau nws muaj txiaj ntsig zoo tshaj nws qhov kev tsim thawj zaug.
Vim li cas SILIMER 5322 tuaj yeem siv los ua kev ua haujlwm siab Silicone-raws li tso tawm Additiverau Rubber Compounds?
Cov ntsiab lus tseem ceeb ntawm SILIKE SILIMER 5322 yog hloov kho polysiloxane nrog cov pab pawg polar active. Nws muaj kev sib raug zoo nrog cov resins, ntoo hmoov, thiab roj hmab tebchaw. Thaum lub sij hawm ua, nws txhim khu cov dispersion ntawm cov roj hmab tebchaw yam tsis cuam tshuam nrog kev ua tau zoo ntawm compatibilizers nyob rau hauv formulation. SILIMER 5322 tsis yog tsuas yog txhim kho cov txheej txheem ntawm lub hauv paus cob, tab sis kuj tseem ua kom lub ntsej muag smoother tiav rau cov khoom kawg, ua kom zoo dua cov tshuaj ntxiv xws li waxes lossis stearates.
