Astaamaha silikoonka loogu talagalay caaryada dheeriga ah
1. Ku darida nooca silica jel waa laba qaybood oo AB ah.Markaad isticmaalayso, ku qas labada miisaan ee 1: 1 oo walaaq si siman.Waxay qaadataa 30 daqiiqo oo wakhtiga qalliinka ah iyo 2 saacadood oo waqti daaweyn ah.Waxaa laga saari karaa 8 saacadood ka dib.Isticmaal caaryada, ama ku rid foornada oo ku dir ilaa 100 darajo Celsius 10 daqiiqo si aad u dhamaystirto daaweynta.
2. Adaggu waxa loo qaybiyaa sub-eber super-jilicsan silica jel iyo 0A-60A caaryada silica gel, kaas oo leh faa'iidooyinka midab la'aanta muddada dheer iyo barti wanaagsan.
3. viscosity heerkulka caadiga ah ee nooca-dheer silica jel waa ilaa 10,000, taas oo aad u khafiif ah sida jel silica nooca uumi, sidaas darteed waxa loo isticmaali karaa sida alaabta ceeriin for qaabaynta.
4. Ku darida nooca silica jel waxa kale oo loo yaqaan platinum cured silica gel.Noocan ah alaabta ceeriin ee silikoonku waxay isticmaashaa platinum sida kicinta falcelinta polymerization.Ma soo saarto wax soo saarka qudhunka.Ma laha wax ur ah waxaana si weyn loogu isticmaalaa samaynta caaryada cuntada iyo alaabta galmada ee qaangaarka ah.Waa shay leh heerka ugu sarreeya ee ilaalinta deegaanka ee silica gelsyada.
5. Nooca silica-ga ah ee lagu daro waa dareere hufan, iyo midabyo midab leh ayaa lagu qasi karaa koollada midabka deegaanka ee saaxiibtinimo.
6. Silikoon dheeri ah ayaa lagu daweyn karaa heerkulka qolka ama waxaa lagu kululayn karaa si loo dedejiyo daaweynta.Kaydinta maalinlaha ah waxay u adkeysan kartaa heerkulka hoose ee -60 ° C iyo kulaylka sare ee 350 ° C iyada oo aan saameyn ku yeelan dabeecadda silikoonka deegaanka u saaxiibka ah ee cuntada.
