Cov carbon dub dub li cas cuam tshuam rau cov khoom ntawm cov kua silicone roj hmab?
Tom qab thiab cov txiaj ntsig ntawm cov kua silicone roj hmab
Los ntawm ib txwm silicone mus ua kua silicone
Kev txhim kho cov kua silicone roj hmab yog ze rau txoj kev kawm ntawm Silicon ntsiab lus, thiab qhov kev tshawb pom ntawm Silicon cov ntsiab lus nyob rau xyoo pua 19th nyob rau hauv lub found tshuaj rau nws; Kev thov ntawm silicone cov ntaub ntawv nyob rau hauv nruab nrab-20th caug xyoo tsim kev kawm; Nyob rau xyoo 1970, vim muaj cov kev txwv ntawm cov khoom ntawm cov khoom tawv nqaij roj hmab (xws li cov roj ntsha tsis tshua muaj txiaj ntsig), kev lag luam pib txhim kho cov kua silicone roj hmab; Thaum xyoo 1980s, nws muaj ntau cov khoom lag luam tau pom; Tuam Tshoj tau nkag mus rau cov chaw lag luam Industrialation thaum pib ntawm lub xyoo pua 21st.
Kua Silicone Roj Hmab (LSR rau Luv luv) yog cov kua elastomer cov khoom siv ntawm cov txheej txheem molecular hnyav, hla}} Txuas tus neeg sawv cev thiab lwm yam ntxiv. Nws muaj cov yam ntxwv ntawm siab transparency, siab thiab qis} 60}} 60 degree), kev laus), thiab tsis muaj los ntawm cov khoom thaum lub sijhawm vertolanization. Los ntawm kev txhaj tshuaj molding cov txheej txheem, nws tuaj yeem ua kom tau ntau yam precision thiab cov khoom lag luam nyuaj.
Tam sim no, cov kua Silicone roj hmab tau siv dav hlau xws li cov khoom siv kho mob xws li cov khoom siv kho mob, cov khoom siv khoom noj, electronics thiab khoom siv hluav taws xob, aerospace, thiab lwm yam.
Tseem ceeb tsis thiab lawv qhov kev cuam tshuam ntawmPrecipitated silica
Thaj chaw tshwj xeeb, roj nqus tus nqi, nruab nrab particle loj, thiab dispersibility ntawm cov carbon dub, txheej txheem ntawm cov kua siceve silicone roj hmab.
(1) thaj chaw tshwj xeeb
Thaj chaw nto yog ib qho tseem ceeb ntawm cov yuam sij cuam tshuam rau kev ua tau zoo ntawm cov roj hmab silicone. Qhov chaw tshwj xeeb thaj tsam qis yuav ua rau pom cov txiaj ntsig lub zog tsis txaus ntseeg, thaum thaj chaw tshwj xeeb uas yuav ua rau muaj kev ua tau zoo heev.
(2) cov roj nqus tus nqi
Cov roj nqus cov nqi ncaj qha cuam tshuam rau cov khoom siv mechanical thiab kev ua cov yam ntxwv ntawm Silicone roj hmab. Carbon Dub nrog cov roj av siab tuaj yeem muab cov zog sib xyaw muaj zog, yog li ua kom muaj zog tensile thiab rhuav lub zog.
(3) nruab nrab particle loj
Ntau qhov loj me me loj tuaj yeem ua rau lub teeb ci loj heev thiab txo cov khoom lag luam; Txawm li cas los xij, yog tias qhov loj me me me me me me me me, nws yooj yim los ua agglomeration, uas cuam tshuam rau kev sib txawv ntawm dispersion.
(4) dispersibility
Cov pa roj carbon dub nrog qhov tsis txaus ntseeg tuaj yeem sib xyaw ua ke nyob rau hauv lub system raws li kev txhawb nqa muab tub lim rau cov roj hmab silicone. Cov pab pawg hydroxyl ntawm cov nplaim dej dub lossis cov tshuaj lom neeg ntawm cov roj hmab molecular ntawm cov roj hmab silicone, rhuav tshem lub zog, thiab nyuaj ntawm cov khoom siv roj hmab. Nyob rau tib lub sijhawm, vim lub siab tsis txaus ntseeg ntawm cov carbon dub, nws cov qauv tuaj yeem rhuav tshem thaum lub sijhawm ua, thiab nws tuaj yeem ua ntxiv rau nws cov khoom siv neeg.
