Kev Siv
Ethyl silicate (TEOS) yog cov kua tsis muaj xim, feem ntau yog siv ua cov txheej tiv taus cua sov, cov txheej tiv taus tshuaj lom neeg, cov neeg sawv cev silane coupling, cov organic synthesis intermediates, thiab ua cov khoom siv ua ntej rau cov yeeb yaj kiab chemical vapor deposition (CVD) SiO2 hauv thaj chaw semiconductor, thiab lwm yam. Lub ntsiab lus yaj ntawm ethyl silicate yog -77 ℃, thiab nws lub ntsiab lus kub yog 165.5 ℃. Nws yog me ntsis soluble hauv dej thiab soluble hauv ethanol thiab ether.
Nws yog siv los ua cov khoom siv rwb thaiv tsev hauv kev lag luam hluav taws xob thiab kuj yog tus neeg sawv cev ua rau iav kho qhov muag thiab cov tshuaj coagulant
Siv rau kev ua kom raug raws li cov khoom siv rau cov pwm xuab zeb; Cov hlau nto kho nrog ethyl silicate vapor tuaj yeem tiv thaiv kev xeb thiab dej. Ethyl silicate tuaj yeem siv los impregnate qhov chaw ntawm cov hlau nrog silicon, thiab kev kho cov iav kho qhov muag tuaj yeem ua rau nws lub teeb transmittance nce. Cov hmoov silica zoo heev tsim tom qab hydrolysis tiav tuaj yeem siv los tsim cov phosphors. Ethyl silicate yog cov khoom siv raw ntawm cov roj silicone. Ethyl silicate kuj tseem tuaj yeem siv los tsim cov txheej txheem tiv taus cua sov thiab tshuaj lom neeg. Hauv Nyiv, 90% ntawm ethyl silicate yog siv ua cov khoom siv hauv paus rau cov txheej txheem tiv thaiv xeb (zinc-nplua nuj xim).
Nws yog siv rau hauv cov tshuaj pleev xim uas tiv taus tshuaj lom neeg thiab cov tshuaj pleev xim uas tiv taus cua sov, cov tshuaj silicone thiab cov nplaum uas raug. Tom qab hydrolysis tag nrho, cov hmoov silicon dioxide zoo heev raug tsim tawm, uas yog siv los ua cov phosphors thiab kuj siv tau ua cov tshuaj reagent.
Tetraethoxysilane feem ntau yog siv rau hauv cov iav kho qhov muag, cov tshuaj pleev xim tiv taus tshuaj, cov tshuaj pleev xim tiv taus cua sov thiab cov nplaum. Kev hloov kho cov tshuaj pleev xim tiv thaiv xeb Crosslinking agent, binder, dehydrating agent; Kev tsim cov pob txha catalyst thiab cov silica ntshiab ultrafine.
Ethyl orthosilicate feem ntau yog siv rau hauv cov iav kho qhov muag, cov tshuaj pleev xim tiv taus tshuaj lom neeg, cov tshuaj pleev xim tiv taus cua sov thiab cov nplaum. Kev hloov kho cov tshuaj pleev xim tiv thaiv xeb Crosslinking agent, binder, dehydrating agent; Kev tsim cov pob txha catalyst thiab cov silica ntshiab ultrafine.
Cov ntaub ntawv rwb thaiv tsev rau kev lag luam hluav taws xob, tshuaj pleev xim, cov neeg sawv cev kho iav kho qhov muag, cov tshuaj coagulants, cov tshuaj organic synthesis, cov kuab tshuaj rau kev npaj cov organosilicon
Hauv cov khoom sib xyaw uas tsim H + -magadiite, nws yuav cuam tshuam nrog dodecylamine rau kev kawm txog cov iav bioactive sib xyaw. Nws feem ntau yog siv ua tus precursor hauv kev npaj cov gels qhuav
Ntim thiab Xa Khoom
Ntim: 200kg raws li cov neeg siv khoom xav tau.
Kev xa khoom: yog cov tshuaj lom neeg thiab tuaj yeem xa los ntawm tsheb ciav hlau, dej hiav txwv thiab huab cua.
Tshuag: muaj 500MTs kev nyab xeeb Tshuag
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
