Silicone ntawm Cov Khoom Siv Yas Kho Kom Zoo Nkauj

Cov roj hmab silicone, ua ib yam khoom siv, siv dav hauv cov fwj mus ncig, cov fwj faib, khoom plig, thiab cov khoom siv zaws. Ua ib yam khoom siv uas tsis ua rau ib puag ncig puas tsuaj, tam sim no feem ntau siv rau cov khoom rau poj niam thiab menyuam yaus, tshuaj pleev ib ce, pleev ib ce, khoom siv kho mob, khoom siv sab nraum zoov thiab kev lom zem, thiab rooj tog. Nrog rau kev siv cov mis tshuaj ntsuab tas mus li hauv kev lag luam tshuaj pleev ib ce, nws xav tias kev siv cov roj hmab silicone hauv kev lag luam no yuav qhia txog kev loj hlob tseem ceeb yav tom ntej.

Silicone, yog ib yam khoom siv adsorption uas muaj zog heev thiab yog ib yam khoom tsis yog crystalline nrog cov mis tshuaj mSiO2·nH2O. Nws tsis yaj hauv dej thiab lwm yam kuab tshuaj, tsis muaj ntxhiab, tsis qab, thiab ruaj khov hauv tshuaj. Nws tsis cuam tshuam nrog lwm yam khoom tsuas yog alkali thiab hydrofluoric acid muaj zog xwb. Ntau hom silicone muaj cov qauv micro-pore sib txawv vim yog cov txheej txheem tsim khoom sib txawv. Cov tshuaj lom neeg thiab cov qauv lub cev ntawm silicone txiav txim siab ntau yam ntxwv uas nyuaj rau hloov los ntawm lwm cov khoom zoo sib xws: kev ua tau zoo adsorption, kev ruaj khov thermal zoo, cov khoom tshuaj ruaj khov, thiab lub zog kho tshuab siab.

Cov khoom siv silicone pwm feem ntau yog tsim los ntawm kev muab cov khoom siv roj hmab silicone khov kho nrog cov neeg sawv cev vulcanizing ntxiv rau hauv cov pwm kub siab thiab siv lub tshuab vulcanizing ntawm qhov kub siab. Qhov nyuaj ntawm cov silicone pwm feem ntau yog ntawm 30 ° C thiab 70 ° C. Cov khoom siv raw yog sib xyaw nrog cov xim pastes kom phim cov xim raws li daim ntawv qhia xim Pantone. Cov duab ntawm cov pwm txiav txim siab cov duab ntawm cov khoom silicone pwm. Cov khoom silicone pwm tam sim no yog hom siv dav tshaj plaws hauv kev lag luam silicone.

Cov khoom siv silicone extruded feem ntau yog tsim los ntawm kev extruding silicone los ntawm lub tshuab extrusion. Feem ntau, extruded silicone yog cov duab ntawm cov strips ntev lossis cov raj uas tuaj yeem txiav rau txhua qhov ntev. Txawm li cas los xij, cov duab ntawm extruded silicone yog txwv. Nws yog siv dav hauv cov khoom siv kho mob thiab cov tshuab ua zaub mov.

Cov khoom siv silicone ua kua yog tsim los ntawm kev txhaj tshuaj molding lossis txau molding. Cov khoom no mos, nrog rau qhov nyuaj ntawm 10 ° C txog 40 ° C. Vim lawv mos, lawv siv dav hauv kev ua qauv ntawm tib neeg lub cev, cov ntaub qhwv mis silicone kho mob, thiab lwm yam kev siv.
