Silicone roj muaj ntau yam khoom tshwj xeeb, xws li tsis tshua muaj kub thiab viscosity coefficient, siab thiab kub tsis kam, anti-oxidation, siab flash point, tsis tshua muaj volatility, zoo rwb thaiv tsev, tsis tshua muaj deg nro, tsis muaj corrosion rau hlau, tsis muaj tshuaj lom thiab lwm yam. . Vim tias cov khoom no, cov roj silicone zoo heev rau ntau daim ntawv thov. Ntawm ntau yam roj silicone, methyl silicone roj yog siv dav tshaj plaws thiab ntau yam tseem ceeb hauv cov roj silicone, ua raws li methyl phenyl silicone roj. Ntau cov roj silicone ua haujlwm thiab hloov cov roj silicone feem ntau yog siv rau lub hom phiaj tshwj xeeb.
Khoom: Tsis muaj xim, tsis muaj ntxhiab, tsis muaj tshuaj lom thiab tsis muaj kuab paug.
Kev Siv: Muaj ntau yam viscosities. Nws muaj kev kub siab ua haujlwm, dej tsis kam, hluav taws xob rwb thaiv tsev thiab qhov nro me me. Feem ntau siv los ua cov roj lubricating siab, cov roj tiv thaiv kev vibration, roj insulating, defoaming tus neeg saib xyuas, pwm tso tus neeg sawv cev, tus neeg saib xyuas polishing, tso tus neeg sawv cev thiab lub tshuab nqus tsev twj tso kua mis, thiab lwm yam. thiab lwm yam. Methyl silicone roj yog feem ntau siv. Tom qab emulsification los yog hloov kho, nws yog siv rau du thiab mos kov xov ntawm textile xov, thiab emulsified silicone roj kuj ntxiv rau cov tshuaj zawv plaub hau ntawm cov khoom tu txhua hnub los txhim kho lubricity ntawm cov plaub hau. Tsis tas li ntawd, muaj ethyl silicone roj, methyl phenyl silicone roj, nitrile-muaj silicone roj, polyether hloov silicone roj (dej-soluble silicone roj), thiab lwm yam.
Kev npaj los yog qhov chaw: oily khoom tau los ntawm hydrolysis thiab polycondensation ntawm difunctional thiab monofunctional organosilicon monomers.
Dimethicone
XY-dimethicone roj, tshuaj npe polydimethylsiloxane, tshuaj formula yog: (CH3)3SiO[(CH3)2SiO]n·Si(CH3)3
Dimethicone yog cov khoom tsis muaj xim thiab pob tshab tshiab hluavtaws polymer nrog ntau yam sib txawv viscosities (5cps txog 8 lab cps), los ntawm cov kua dej tsis tshua muaj mus rau cov khoom tuab tuab. Cov khoom no muaj qhov tshwj xeeb smoothness, softness, hydrophobicity, zoo tshuaj stability, zoo heev hluav taws xob rwb thaiv tsev thiab kub thiab kub tsis kam. Nws muaj qhov taw tes siab flash thiab qis qis, thiab tuaj yeem siv tau ntev ntawm -50 degree - ntxiv rau 200 degree . Nws muaj me me viscosity-kub coefficient, siab compressibility, qis nto nro, zoo hydrophobicity thiab noo noo tsis kam, thiab me me thermal conductivity.
