Raws li tau hais los saum toj no, ib qho ntawm daim ntaub ntawv tseem ceeb ntawm Silane Coupling tus neeg sawv cev yog kev ua cov kab uas tsis muaj kab mob hauv cov organic polymers. Lub tom kawg ntawm Silane Coupling tus neeg saib xyuas kev kho mob, nws tig nws qhov dej ntws ntim qaub ntim qis, uas yuav tiv thaiv tsis tau particle buildup thiab ntse gelled polymer nyob rau hauv qhov system, kuj yuav ua kom lub pob ntawm cov hluavtaws muaj zog rau reinforcing muab tub lim, reinforcing fillers thiab polymer nplaum ua ke.
Txawm li cas los, cov nyom ntawm Silane Coupling tus neeg ua hauj lwm kuj muaj feem xyuam rau hom thiab tus nqi ntawm Silane Coupling tus neeg sawv cev, tus yam ntxwv ntawm cov substrate, cov khoom ntawm cov duab los yog cov polymer, thiab daim ntawv thov sij hawm, txoj kev thiab tej yam kev mob. Ntu no qhia txog ob daim ntawv thov ntawm tus neeg sawv cev ntawm Silane Coupling, kev kho qhov chaw thiab kev sib xyaw ua ke. Lub qub txoj kev yog kho qhov saum npoo ntawm substrate nrog Silane Coupling tus neeg saib xyuas dilute kua. Txoj kev tom kawg yog ntxiv Silane Coupling tus neeg saib xyuas kev sib tov los yog cov tshuaj tov rau hauv qhov sib xyaw ua ke ntawm polymers thiab cov fillers, uas yog qhov tshwj xeeb tshaj yog rau qhov khoom siv uas yuav tsum tau ua kom muaj thiab tov.
Silane Coupling tus neeg saib xyuas noj calculation
Cov naj npawb ntawm cov tshuaj tiv thaiv cov ntsiab lus ntawm ib chav dej ntawm cov dej tshuaj kho thiab cov thickness ntawm Silane Coupling tus neeg saib xyuas sab nrauv yog qhov tseem ceeb los txiav txim seb tus nqi ntawm cov neeg ua hauj lwm coupling yuav tsum tau rau siliconization ntawm cov txheej txheem substrate. Yuav kom monomolecular txheej, cov ntsiab lus ntawm Si-OH hauv qhov matrix tau txiav txim siab. Paub, feem ntau ntawm cov silicon substrate uas muaj Si - OH yog 4-12 / mu ㎡, thiab cov teeb tis, 1 molsilane Coupling tus neeg saib xyuas yuav npog txog 7500 m2 ntawm cov substrate. Silane Coupling tus neeg sawv cev nrog ntau hom kev sib txuas ntawm pawg hydrolyzable yuav cuam tshuam qhov tseeb ntawm kev xam los ntawm nws qhov kev sib tw haum. Yog hais tias qhov kev kho mob yuav kho nrog Y3SiX, ib cov txheej txheem monomolecular txheej txheem nrog tus nqi sib yuav tau. Txawm li cas los, vim hais tias Y3SiX yog siab nyob rau hauv tus nqi thiab tsis muaj zog hydrolysis tsis kam, nws tsis muaj tus nqi siv. Tsis tas li ntawd, tus lej ntawm Si-OH nyob saum npoo ntawm qhov ntsuas kuj txawv nrog lub cua kub.
Si - OH, piv txwv li, tus naj npawb yog 5.3 tauj ㎡, siliceous substrates los ntawm qis dua 400 ℃ los yog 800 ℃ tom qab kho cov khoom kub, Si - OH nqi yuav raug txo kom tsawg li 2.6 / mu ㎡ los sis <1 mu=""> Ntawm qhov tsis sib xws, siab Si-OH cov ntsiab lus yuav muab tau los ntawm kev kho matrix nrog hydrochloric acid. Qhov saum npoo ntawm substrate yuav kho nrog alkaline detergent rau daim ntawv silicone cawv ntxoov ntxoo
