Muaj qhov sib txawv tseem ceeb ntawm cov roj hydrogen silicone roj siab thiab qis hauv cov ntsiab lus ntawm cov qauv tshuaj, lub cev thiab kev siv.
1. Cov qauv tshuaj thiab lub cev muaj zog:
High hydrogen silicone roj: nrog ntau pab pawg muaj hydrogen, nws cov molecular kev sib cuam tshuam quab yuam muaj zog, thiab viscosity kuj siab. Cov kua dej no feem ntau yog linear lossis branched polysiloxanes nyob rau hauv daim ntawv ntawm cov kua dawb los yog yellowish. Vim muaj ntau ntawm silicon-oxygen bonds, methyl thiab ethyl pawg feem ntau yog txuas rau cov ntawv cog lus.
Tsawg-hydrogen silicone roj: muaj tsawg dua hydrogen-muaj pawg thiab muaj qis dua viscosity. Si-O saw nyob rau hauv nws cov qauv molecular yog linear polymer. Tsis tas li ntawd, cov roj silicone uas tsis muaj hydrogenated muaj ntau cov phenyl thiab phenolic pawg, ua rau lawv lub cev sib txawv ntawm cov roj uas muaj hydrogenated silicone.
2.Siv:
High hydrogen silicone roj: tsuas yog siv nyob rau hauv industrial lubricants, txij nkawm roj thiab surfactants. Lawv tuaj yeem tsim cov txheej txheem tiv thaiv zoo ib yam li cov yeeb yaj kiab molecular thaum lawv nkag mus rau hauv cov chaw hlau, tiv thaiv oxidation, corrosion thiab hnav ntawm cov hlau nto, thiab ua lub luag haujlwm hauv kev saib xyuas. Tsis tas li ntawd, high-hydrogen silicone roj kuj tseem siv tau los ua surfactants los ua kom cov dej noo, permeability thiab antistatic zog ntawm cov tshuaj. Hauv ntawv ntau lawm, high-hydrogen silicone kua yog siv los tiv thaiv-stick cais thiab crosslinkers. Lawv kuj tuaj yeem siv los ua cov txheej txheem dej tsis zoo rau cov ntaub, iav, ceramics, ntawv, tawv khoom, cov ntaub ntawv hlau, cement, marble, thiab lwm yam ntaub ntawv.
Tsawg-hydrogen silicone roj: feem ntau siv hauv cov tshuaj pleev ib ce, cov khoom tu tawv nqaij, lubricants, lubricants thiab tshuaj pleev thaiv hnub, thiab lwm yam. Lawv tau siv dav hauv cov teb no vim tias lawv muaj peev xwm tawg tau zoo nyob rau hauv ob qho tib si aqueous thiab roj theem. Tsawg hydrogenated silicone kua muaj tsawg hydrogen nyob rau hauv lawv cov qauv molecular, uas yuav tsum tau tag nrho dispersed nyob rau hauv dej-raws li primers, ua rau lub pob tshab, gloss thiab hnav tsis kam ntawm primer. Nyob rau tib lub sijhawm, vim nws tsis tshua muaj viscosity thiab tshuaj lom neeg ruaj khov, nws tuaj yeem siv los ua cov roj nplua nyeem kom txo qis hnav thiab suab nrov, thiab txuas ntxiv lub neej kev pabcuam ntawm cov khoom. Tsawg-hydrogen silicone roj kuj tseem siv tau los ua ib qho nruab nrab hauv kev sib txuas ntawm cov roj silicone hloov thiab ua tus crosslinker rau additive molding silicone roj hmab.
Hauv kev xaus, muaj qhov sib txawv tseem ceeb ntawm cov roj hydrogen silicone roj siab thiab qis hauv cov ntsiab lus ntawm cov qauv tshuaj, lub cev thiab kev siv. Hauv kev siv cov tswv yim, txoj cai ntawm silicone roj yuav tsum raug xaiv raws li cov chaw sib txawv thiab xav tau kom tau txais txiaj ntsig zoo tshaj plaws.
