Peb daim ntawv ntawm precipitated silica
Muaj peb daim ntawv los silica: hmoov, tsom iav, thiab thaiv, txhua tus muaj cov yam ntxwv sib txawv thiab qhov zoo, raws li nram no:
Hmoov silica.
Cov yam ntxwv: hmoov silica feem ntau yog ib qho dawb amorphous hmoov zoo nrog qhov loj me me ntau ntau, thaj chaw tshwj xeeb thaj chaw, thiab porosity nto tshwj xeeb. Silicon atoms nyob rau hauv nws txheej txheej txheej txheem ntau cov pawg hydroxyl vim tsis muaj txiaj ntsig valus, nthuav qhia cov kev kos duab muaj zog thiab tshuaj lom neeg inertness.
Cov txiaj ntsig zoo: hmoov silica muaj cov khoom lag luam tsis txaus thiab cov adsorption, xws li cov roj hmab tshwj xeeb cov roj hmab, txheej ntxiv cov roj hmab, thiab lwm yam
Tsis tas li ntawd, nws muaj cov kub ua hauj lwm, corrosion tsis kam, thiab zoo hluav taws xob kev siv hluav taws xob, ua kom haum rau kev siv cov khoom siv kev lag luam thiab cov cab kuj
.
Microsherphy symed silica
Cov yam ntxwv: Xaiv cov khoom silica yog spherical lossis quasi spherical particle nrog siab purity thiab zoo dispersibility. Nws saum toj yog tus thiab qhov loj me me yog qhov kev npaj tau zoo, tsim nyog rau kev npaj los ntawm cov txheej txheem tshwj xeeb xws li Soldium silicate thiab ps nqi.
Cov txiaj ntsig zoo: Micro hlaws zoo li silica, vim nws cov kheej kheej, muaj cov nplaim hluavtaws siab thiab muaj lwm daim teb, uas tuaj yeem txhim kho cov pob tshab thiab glossiness ntawm cov khoom. Tsis tas li ntawd, nws cov roj av qis thiab cov dej nqus dej siab ua rau nws tseem ceeb rau kev siv hauv cov tshuaj pleev ib ce thiab chaw muag tshuaj
.
Chunky silica
Cov yam ntxwv: Blocky silica feem ntau yog cov nplov dawb lossis cov particle nrog qhov loj me me thiab ntau morphology. Nws qhov ntom yog qhov tseem ceeb.
Cov txiaj ntsig: Vim nws cov loj dua qhov loj me thiab ntau dua li cov khoom siv hluav taws xob muaj zog thiab hnav kom haum rau cov neeg siv roj hmab thiab muab tub lim
Tsis tas li ntawd, nws muaj cov cua sov zoo heev tiv thaiv thiab cov khoom sib xyaw tsawg, ua rau nws cov khoom siv tseem ceeb hauv cov log tsheb tsim khoom.
Peb cov qauv ntawm cov dej nag dhau los silica txhua tus muaj lawv tus cwj pwm thiab cov txiaj ntsig zoo, thiab hmoov silica yog qhov tsim nyog rau cov ntawv thov uas yuav tsum muaj cov chaw nyob hauv thaj av loj; Microsphe cov Silica yog qhov tsim nyog rau kev siv hauv cov txheej txheej thiab cov tshuaj pleev ib ce vim nws cov txheej txheem sib txawv thiab kev coj dawb huv; Blocky silica yog dav siv hauv kev lag luam roj hmab vim nws lub zog zog thiab hnav tsis kam.
