Qhov txawv ntawm Sab Thiab Kawg Hydrogen

Sab hydrogen silicone roj thiab kawg hydrogen silicone roj yog ob hom roj silicone, thiab lawv muaj qee qhov sib txawv hauv cov qauv tshuaj, cov khoom thiab kev siv.
Ua ntej tshaj plaws, los ntawm qhov pom ntawm cov qauv tshuaj, qhov sib txawv tseem ceeb ntawm sab thiab kawg hydrogen-muaj silicone roj yog txoj hauj lwm ntawm pawg hydrosilicon hauv cov molecule. Hauv cov qauv tshuaj ntawm hydrogen-muaj silicone roj, pawg hydrosilicon nyob rau ntawm ob qho kawg ntawm cov saw hlau molecular, uas yog, ob lub silicon atoms hauv cov molecule txuas nrog ob lub hydrogen atoms. Lub sab hydrogen-muaj silicone roj sib txawv, thiab nws pawg hydrosilicon nyob rau ntawm ib sab ntawm cov saw molecular, uas yog, tsuas yog ib tug silicon atom nyob rau hauv lub molecule txuas nrog hydrogen atom, thiab lwm yam silicon atom txuas nrog rau lwm yam. pab pawg.
Qhov sib txawv ntawm cov qauv tshuaj no ua rau muaj qhov sib txawv ntawm lawv cov khoom. Qhov kawg hydrogen-muaj silicone roj qhia tau hais tias zoo emulsification muaj peev xwm nyob rau hauv aqueous tov vim hais tias cov molecule muaj ob silicon hydrogen bonds. Cov dej emulsification kev ua tau zoo ntawm sab-hydrogen-muaj silicone roj kuj tsis zoo vim tias tsuas muaj ib daim ntawv cog lus silicon hydrogen xwb. Tsis tas li ntawd, hydrogen-muaj silicone roj kuj muaj cov zoo solubility thiab emulsification zog, uas ua rau nws lug siv raws li ib tug emulsifier nyob rau hauv surfactant, tshuaj, tshuaj pleev ib ce thiab lwm yam teb.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov, kuj muaj kev sib txawv ntawm sab thiab kawg hydrogen-muaj silicone roj. Vim muaj tshuaj lom neeg thiab thermal stability ntawm sab-hydrogen-muaj silicone roj, nws yog feem ntau siv los ua tus neeg sawv cev crosslinking hauv kev npaj ntawm polysiloxanes (tseem hu ua silicone polymers). Cov roj uas muaj cov roj silicone ua lub luag haujlwm tseem ceeb hauv kev tsim cov silicone hloov block silicone roj, kua roj hmab silicone thiab lwm yam khoom vim nws cov khoom tshwj xeeb emulsifying, thiab tseem yog ib qho tseem ceeb raw khoom rau kev sib txuas ntawm tshwj xeeb silicone surfactants thiab dendritic polymers. .
Feem ntau, muaj qhov sib txawv ntawm cov qauv tshuaj, cov khoom siv thiab kev siv ntawm sab thiab kawg cov roj silicone uas muaj hydrogen. Kev nkag siab txog qhov sib txawv no pab peb xaiv tau zoo dua thiab siv ob hom roj silicone.
