Kev siv cov nplaim hluav taws xob feem ntau muaj xws li cov txheej txheem ntawm cov txheej txheem thiab cov kev sib txuas ncaj qha, tus qub yog muab sib txuas nrog kev sib koom tes ntawm cov neeg ua hauj lwm, uas yog ib qho khoom siv ua ntej thiab cov ntaub so ntsaws, koom nrog tus neeg saib xyuas kev sib koom tes.
(1) txheej txheem pretreatment
Yuav Nplaim Retardant Tus Neeg Sawv Cev ntawm 0.5 ~ 1% concentration of dilute solution, thaum siv los ntxuav huv plhaws nplua nrog txheej nyias ntawm kua nplaum tom qab ziab. Cov tshuaj siv dej thiab haus cawv (methoxy silane xaiv methanol, ethoxy silane xaiv ethanol), dej los yog dej cawv sib tov, thiab tsis muaj dej muaj fluorine ion thiab pheej yig thiab tsis muaj tshuaj lom ethanol, isopropanol yog ib qho zoo. Dhau li ntawm ammonia hydroxyl silane, los ntawm lwm yam nplaim hluav taws xob dispensing kua yog ntxiv rau acetic acid hydrolysis catalyst, thiab tus nqi pH rau 3.5 ~ 5.5. Ntev ntev alkil thiab phenylsilane tsis haum rau cov kua dej vim lawv cov neeg tsis muaj zog. Cov hydrolysis ntawm chlorosilane thiab ethoxy silane yog nrog kev sib sib zog nqus dej ua ke, thiab nws tsis haum siv dej los yog dej haus cawv. Dej soluble Low Flame Retent Agent, tuaj yeem koom thawj 0.1 ~ 0.2% (feem ntau pawg) ntawm nonionic nta nquag Agent, thiab ces muab dej rau hauv dej emulsion siv.
Nplaim hluav taws tuaj rau hauv qhov kev daws teeb meem, yog qhov zoo rau cov nplaim hluav taws kub ntawm cov khoom siv, cov dispersion, solvent yog sib xyaw dej thiab haus cawv, cov tshuaj feem ntau yog silane (20%), cawv (72%), dej (8%), cawv feem ntau yog ethanol (rau ethoxy silane) methanol (methoxy silane) thiab isopropanol (tsis yooj yim soluble ethanol, methanol silane) los ntawm silane hydrolysis tshaj tawm ntsig txog kev pH, qeeb tshaj plaws, acid, alkali sai dua, feem ntau yog yuav tsum kho kho tus nqi pauv, ntxiv rau cov amino silane, Lwm cov silane yuav ntxiv nrog ib qho me me acetic acid kom kho PH mus rau 4-5. Amino silane yog alkaline thiab tsis tas yuav hloov. Vim hais tias silane hydrolysis, tsis tuaj yeem ntev cia, tau zoo dua match tam sim no siv, tau zoo siv li nyob rau hauv ib teev.
(2) ntxiv cov kev ncaj qha
Lub Nplaim Retardant Agent ncaj qha rau ntxiv rau cov txheej txheem nplaum, rau qhov nyiaj matrix cob rau tus nqi 1 ~ 5%. Nyob ntawm lub diffusion ntawm lub molecules, lub coupling agent molecules migrate mus rau tsevneeg txuas rau kev sib koom tes. Rau cov nplaum uas yuav tsum tau kho, nws yuav tsum tau muab tso rau lub sijhawm ua ntej kev kho, kom tus neeg sib tw ua tus neeg tuaj yeem tuaj yeem ua kom tiav cov txheej txheem tsiv chaw, thiaj li yuav tau txais qhov zoo dua. Hauv kev xyaum ua ke, feem ntau tsim ib txheej txheej rau saum npoo av, tab sis dab tsi tiag tiag yog cov txheej txheem monomolecular, yog li qhov ntau ntawm cov couplers tsis tas yuav ntev li.
