Hydrophilic silicones txawv heev ntawm cov pa silicones nyob rau hauv ntau txoj kev. Nov yog qhov sib piv tshwj xeeb ntawm ob yam khoom:
Ua ntej tshaj plaws, los ntawm kev xav ntawm cov qauv tshuaj, ob qho tib si yog nyob rau hauv qeb ntawm organosilicon tebchaw, uas yog, ob qho tib si muaj Si-C bonds, thiab tsawg kawg yog ib pawg organic txuas ncaj qha mus rau silicon atom. Txawm li cas los xij, hydrophilic silicones tau dhau los kho cov qauv kev hloov kho tshwj xeeb, uas ua rau lawv cov qauv molecular yooj yim los khi rau cov dej molecules, yog li nthuav tawm cov khoom zoo hydrophilic.
Hais txog cov yam ntxwv ntawm kev ua tau zoo, qhov sib txawv tseem ceeb ntawm hydrophilic silicones thiab tsoos silicones yog lawv cov hydrophilicity thiab permeability. Cov pa silicones feem ntau muaj kev tiv thaiv zoo rau qhov kub thiab txias, tsis kub, huab cua tsis kam thiab hluav taws xob rwb thaiv tsev, uas ua rau lawv siv dav hauv aerospace, khoom siv hluav taws xob, kev tsim kho thiab lwm yam. Txawm li cas los xij, vim cov dej-repellent ntawm cov tshuaj silicones, lawv daim ntawv thov hauv textiles thiab lwm yam kev lag luam raug txwv.
Hauv qhov sib piv, hydrophilic silicones muaj cov dej permeability zoo heev thiab hydrophilicity, uas tso cai rau lawv muab cov huab cua zoo permeability thiab hws nqus cov khoom rau textiles. Nyob rau tib lub sijhawm, hydrophilic silicones kuj muaj qhov muag zoo thiab plam, uas tuaj yeem txhim kho kev xav ntawm cov ntaub. Tsis tas li ntawd, hydrophilic silicones impart zoo heev antistatic thiab stain tsis kam rau fabrics, txhim kho kev ua tau zoo ntawm fabrics.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov teb, hydrophilic silicones yog tsuas yog siv nyob rau hauv kev ua tiav ntawm textiles, tawv, ntawv thiab lwm yam ntaub ntawv. Los ntawm kev ntxiv hydrophilic silicone softeners, cov ntaub ntawv no tuaj yeem ua tau yooj yim dua, ua pa thiab tawm hws-absorbent, thaum txhim kho lawv cov antistatic thiab stain resistance. Tsis tas li ntawd, hydrophilic silicones kuj tseem siv tau los npaj cov ntaub ntawv txheej nrog cov haujlwm tshwj xeeb, xws li cov dej tsis muaj dej thiab cov dej noo-permeable, antifouling coatings, thiab lwm yam.
Hauv cov ntsiab lus, muaj qhov sib txawv tseem ceeb ntawm hydrophilic silicones thiab tsoos silicones nyob rau hauv cov ntsiab lus ntawm cov qauv tshuaj, cov yam ntxwv ntawm kev ua haujlwm thiab daim ntawv thov. Cov kev sib txawv no ua rau hydrophilic silicones tshwj xeeb hauv qee qhov chaw tshwj xeeb thiab muaj kev cia siab rau daim ntawv thov.
