silane coupling tus neeg sawv cev
Synonyms in English
coupling reagent
chemical khoom
Cov mis molecular ntawm silane coupling tus neeg sawv cev feem ntau yog YR-Si (OR) 3 (hauv cov mis, Y-organic functional pawg, SiOR-silane oxy pawg).Silanoxy pawg yog reactive rau inorganic teeb meem, thiab organic functional pawg yog reactive los yog sib xws rau cov organic teeb meem.Yog li ntawd, thaum lub silane coupling tus neeg sawv cev nyob nruab nrab ntawm cov inorganic thiab organic interface, cov organic matrix-silane coupling tus neeg saib xyuas thiab inorganic matrix binding txheej yuav tsim.[1] Cov silane coupling agents yog A151 (vinyl triethoxylsilane), A171 (vinyl trimethoxylsilane), A172 (vinyl triethoxylsilane)
Khoom taw qhia thiab nta
Ib qho organic silicon monOMER muaj ob lossis ntau dua cov tshuaj tiv thaiv sib txawv hauv ib lub molecule uas tuaj yeem siv tshuaj lom neeg sib raug zoo (kwv yees) nrog cov ntaub ntawv organic THIAB inorganic.Cov tshuaj formula ntawm silane coupling tus neeg sawv cev yog RSiX3.X sawv cev rau pawg neeg ua haujlwm hydrolytic, uas tuaj yeem ua ke nrog pawg methoxy, pawg ethoxy, tus neeg sawv cev fibrinolytic thiab cov khoom siv tsis muaj zog (iav, hlau, SiO2).R sawv cev rau pawg neeg ua haujlwm organic, uas tuaj yeem ua ke nrog vinyl, ethoxy, methacrylic acid, amino, sulfhydryl thiab lwm yam organic pawg nrog rau cov khoom siv tsis zoo, ntau yam hluavtaws resins, cov tshuaj tiv thaiv roj hmab.
siv
Nws tuaj yeem txhim kho kev sib raug zoo ntawm iav fiber ntau thiab cob, txhim kho lub zog, hluav taws xob, dej tsis kam, kev nyab xeeb thiab lwm yam khoom ntawm iav fiber ntau cov ntaub ntawv sib xyaw, txawm tias nyob hauv lub xeev ntub, nws txhim kho cov khoom siv sib xyaw ntawm cov khoom sib xyaw, cov nyhuv kuj tseem ceeb heev.Kev siv cov silane coupling tus neeg saib xyuas hauv iav fiber ntau tau ntau heev, rau qhov no ntawm silane coupling tus neeg sawv cev suav txog li 50% ntawm tag nrho cov kev siv, uas yog siv ntau hom yog vinyl silane, amino silane, methylallyl oxy silane thiab lwm yam. .Cov muab tub lim tuaj yeem kho qhov chaw ua ntej lossis ncaj qha ntxiv rau cov resin.Nws tuaj yeem txhim kho qhov tawg thiab adhesion ntawm fillers hauv resin, txhim kho kev sib raug zoo ntawm inorganic fillers thiab cob, txhim kho cov txheej txheem kev ua tau zoo thiab txhim kho cov khoom siv hluav taws xob, hluav taws xob thiab huab cua tsis kam ntawm cov yas ntim (suav nrog roj hmab).Nws tuaj yeem txhim kho lawv lub zog sib txuas, dej tsis kam, kev nyab xeeb thiab lwm yam khoom.Silane coupling agents feem ntau tuaj yeem daws qhov teeb meem uas qee cov ntaub ntawv tsis tuaj yeem sib txuas tau ntev.Lub hauv paus ntsiab lus ntawm silane coupling tus neeg sawv cev ua viscosifier yog tias nws muaj ob pawg;Ib pawg tuaj yeem khi rau cov khoom siv pob txha;Lwm pab pawg tuaj yeem ua ke nrog cov ntaub ntawv polymer lossis cov nplaum, thiaj li tsim cov tshuaj lom neeg muaj zog ntawm kev sib txuas sib txuas, txhim kho kev sib raug zoo zoo.Daim ntawv thov ntawm silane coupling tus neeg saib xyuas feem ntau muaj peb txoj kev: ib qho yog raws li tus neeg saib xyuas kev kho mob ntawm cov khoom siv pob txha;Ob yog ntxiv rau cov nplaum, peb yog ncaj qha ntxiv rau cov khoom siv polymer.Los ntawm qhov kev xav ntawm muab kev ua si tag nrho rau nws qhov kev ua tau zoo thiab txo cov nqi, thawj ob txoj hauv kev zoo dua.
pob thiab thauj
B. Cov khoom no tuaj yeem siv tau, 25KG, 200KG, 1000KG, chim.
C. Khaws ntim rau hauv qhov chaw txias, qhuav thiab qhov cua nyob hauv tsev.Cov thawv ntim khoom yuav tsum tau muab kaw kom nruj tom qab siv txhua zaus ua ntej siv.
D. Cov khoom no yuav tsum raug kaw kom zoo thaum lub sijhawm thauj mus los kom tsis txhob ya raws, muaj zog alkali thiab acid, nag thiab lwm yam impurities los ntawm kev sib xyaw.
