Silicone ua npuas ncauj, tseem hu ua molded silicone, yog cov khoom siv roj hmab uas muaj qhov ntxeem tau ua los ntawm roj hmab silicone ua cov khoom siv hauv paus thiab tsim los ntawm kev ua npuas ncauj.

 

　　Nrog rau kev txhim kho thiab hloov kho tshiab ntawm cov thev naus laus zis ua npuas ncauj, tab sis kuj vim nws cov yam ntxwv zoo tshaj plaws, cov chaw siv tau dav dua, xws li cov ntaub thaiv sealing, cov ntaub qhwv cushioning, cov gaskets tsim kho, cov ntaub ntawv cais kev co, cov khoom siv tiv thaiv thiab lwm yam.

 

Lub hauv paus ntsiab lus ntawm silicone ua npuas ncauj

 

　　Ua npuas dej silicone roj hmab, lub hauv paus ntsiab lus yog ntxiv cov neeg sawv cev ua npuas dej rau hauv cov roj hmab silicone xaiv, ua kom sov lub xeev siab vulcanization silicone roj hmab ua npuas dej, roj hmab nthuav dav los ua cov qauv npuas zoo li daim txhuam cev. Cov yam tseem ceeb uas txiav txim siab thiab cuam tshuam rau cov qauv ntawm cov npuas dej yog qhov ntau ntawm cov roj uas tsim los ntawm cov neeg sawv cev tshuab, qhov ceev ntawm cov roj hmab diffusion hauv roj hmab, qhov viscosity ntawm roj hmab thiab qhov ceev ntawm vulcanization. Yuav kom ua tau cov khoom ua npuas dej silicone zoo dua, kev xaiv cov neeg sawv cev ua npuas dej thiab cov roj hmab vulcanization system yog qhov tseem ceeb.

 

　　Cov txheej txheem tsim cov ua npuas ncauj silicone

 

　　Ua npuas ncauj silicone yuav tsum tau dhau los ntawm ntau cov txheej txheem tsim khoom, kev siv tshuab ua tiav, txhua qhov txuas yuav muaj feem cuam tshuam rau cov ua npuas ncauj silicone tiav lawm.

 

　　1, plasticizing (uas yog, qhov plasticity ntawm cov roj hmab nyoos refining. Uas yog, tsis muaj additives hauv lub tshuab qhib refining refining. Cia cov roj hmab mos kom yaj rau hauv tus neeg sawv cev koom tes (los npaj rau kev sib tov).

 

　　Lub ntsiab lus ntawm kev ua kom cov roj hmab nyoos yog kom tawg thiab rhuav tshem cov saw hlau macromolecular ntawm roj hmab, txhim kho qhov yas ntawm roj hmab, thiab ua kom yooj yim rau kev sib tov thiab sib xyaw. Hauv kev tsim cov khoom siv roj hmab ua npuas ncauj, cov roj hmab nyoos yog plasticized tag nrho, yuav ua rau cov roj hmab plasticity zoo dua, yooj yim dua los ua kom lub qhov npuas sib npaug, qhov ceev tsawg, cov khoom me me shrinkage.

 

2, sib tov, uas yog, cov roj hmab yas ntxiv ntau yam khoom siv (additives) rau kev ua kom zoo.

 

Cov txheej txheem sib tov yog ntau yam tshuaj uas muaj nyob rau hauv cov roj hmab nyoos (lossis cov roj hmab yas) thaum lub sijhawm sib xyaw ua ke. Ib yam li kev sib tov ntawm lwm cov ntaub ntawv polymer, txhawm rau ua kom cov khoom sib xws sib xyaw ua ke hauv cov roj hmab nyoos, yuav tsum siv lub zog ua haujlwm ntawm lub tshuab ua kom zoo. Txawm li cas los xij, vim tias cov roj hmab muaj ntau yam khoom sib koom tes, cov khoom morphological ntawm cov neeg sawv cev sib koom tes sib txawv heev, thiab cov kev cuam tshuam ntawm cov neeg sawv cev sib koom tes rau cov txheej txheem sib tov, qib ntawm kev sib xyaw, thiab cov qauv ntawm cov roj hmab kuj zoo heev, yog li cov txheej txheem sib tov ntawm roj hmab nyuaj dua li lwm cov ntaub ntawv polymer.

 

Cov txheej txheem sib tov muaj qhov cuam tshuam tseem ceeb heev rau kev ua haujlwm ntawm cov roj hmab. Kev sib tov tsis zoo, cov roj hmab yuav tsis sib xws ntawm cov khoom sib xws, cov roj hmab plasticity siab dhau lossis qis dhau, hlawv, te thiab lwm yam xwm txheej, uas yuav tsis tsuas yog ua rau cov txheej txheem calendering, nias, molding thiab vulcanization tsis tuaj yeem ua tiav li qub, tab sis kuj ua rau cov khoom tiav lawm puas tsuaj, thiab tej zaum yuav ua rau cov khoom siv tas sij hawm sai. Yog li ntawd, kev sib tov yog ib qho ntawm cov txheej txheem tseem ceeb hauv kev ua cov roj hmab.

 

　　3,Chaw nres tsheb

 

　　Cov roj hmab hauv kev sib tov tiav lawm, yuav tsum tau muab tso rau lub sijhawm tsim nyog, yog li ntawd ntau yam khoom ntxiv hauv kev sib tov ntawm cov roj hmab tau tawg tag nrho, cov khoom ntxiv roj hmab tau tawg ntau dua, qhov ruaj khov ntawm cov khoom loj, qhov du ntawm qhov chaw, qhov sib npaug ntawm cov npuas kuj zoo dua.

 

　　3,Kub

 

　　Cov roj hmab ua npuas ncauj rhiab heev rau qhov kub thiab txias, tib hom roj hmab, cov nyhuv ua npuas ncauj tsis zoo ib yam ntawm qhov kub thiab txias sib txawv, vim tias lub kaw lus ua npuas ncauj thiab lub kaw lus vulcanization rhiab heev rau qhov kub ntawm ntau qib sib txawv, lub kaw lus hloov pauv, qib sib phim ntawm qhov sib txawv, cov nyhuv kuj txawv.

 

　　4, kev txhaj tshuaj

 

　　Cov khoom siv roj hmab ua npuas ncauj ua cov txheej txheem tom qab thiab molding yog extrusion molding, molding, phaj molding, thiab lwm yam, raws li cov qauv xav tau ntawm cov khoom tiav, cov lus qhia, ntev, qhov loj me, cov duab, qhov nyuaj, xim sib txawv, nrog rau cov kev xav tau tshwj xeeb ntawm cov duab kos, koj tuaj yeem ua cov kev hloov kho tus kheej tsis yog tus qauv.
