Xov xwm

A) Coupling agent:
Organic ua haujlwmalkoxysilane uayog siv rau ob peb cov organic polymers thiab inorganic cov ntaub ntawv, thiab cov yam ntxwv ntawm daim ntawv thov no yog ntxiv dag zog.Piv txwv li, iav fiber ntau thiab pob zeb hauv av muab sib xyaw nrog cov yas thiab roj hmab.Lawv yog siv ua ke nrog thermosetting thiab thermoplastic systems.Mineral fillers, xws li dawb carbon dub, talc, Wollastonite, av nplaum thiab lwm yam ntaub ntawv, yog ntxiv ncaj qha rau hauv cov txheej txheem sib tov los yog ua ntej kho nrogsilane ualos yog hauv cov txheej txheem sib xyaw.
Los ntawm kev siv cov organic ua haujlwm silane ntawm hydrophilic, uas tsis yog Organic cov tshuaj tiv thaiv muab tso rau, cov pob zeb hauv av yuav ua rau muaj zog thiab lipophilic.Kev siv cov iav fiber ntau muaj xws li tsheb lub cev, nkoj, da dej, luam ntawv Circuit Court board, satellite TV kav hlau txais xov, raj yas thiab thawv, thiab lwm yam.

Mineral filling systems muaj xws li cov polypropylene reinforced, dawb carbon dub puv molded yas, silicon carbide sib tsoo log, granular puv polymer qhob, xuab zeb puv casting resin, thiab av nplaum sau EPDM xov hlau thiab cables, nrog rau cov av nplaum puv thiab dawb carbon dub puv roj hmab rau tsheb. log tsheb, khau khau, cov khoom siv kho tshuab, thiab lwm yam kev siv.
B) Adhesive txhawb nqa
Thaum siv los ua cov nplaum thiab primer rau kev sib txuas cov xim, inks, coatings, adhesives, thiab sealants,silane uacoupling agents yog adhesion txhawb nqa.Thaum siv los ua ib qho ntxiv tag nrho, silane yuav tsum tau tsiv mus rau qhov sib cuam tshuam ntawm cov nplaum thiab cov khoom siv kho kom zoo.Thaum siv los ua primer, silane coupling agents yuav tsum tau siv rau cov ntaub ntawv inorganic ua ntej cov khoom sib txuas.
Nyob rau hauv cov ntaub ntawv no, silane yog nyob rau hauv ib tug zoo txoj hauj lwm los ua ib tug bonding enhancer (nyob rau hauv lub interface cheeb tsam).Los ntawm kev siv silane coupling cov neeg ua haujlwm kom raug, txawm tias nyob rau hauv ib puag ncig hnyav, cov kua nplaum nplaum, pleev xim, nplaum, lossis cov nplaum nplaum tuaj yeem tswj tau adhesion.
C) Sulfur dej, dispersant
Siloxanes nrog hydrophobic organic pawg txuas nrog silicon atoms tuaj yeem ua rau cov dej tsis muaj dej tsis zoo nrog tib cov yam ntxwv hydrophobic, thiab siv los ua cov tshuaj hydrophobic ntev ntev hauv tsev, choj, thiab daim ntaub ntawv lawj.Lawv kuj tau siv nyob rau hauv hydrophobic inorganic hmoov kom tso cai rau lawv ntws dawb thiab disperse yooj yim nyob rau hauv organic polymers thiab kua.
D) Crosslinking tus neeg saib xyuas
Organic functional alkoxysilane tuaj yeem cuam tshuam nrog cov organic polymers, khi trialkoxyalkane pawg rau cov saw tseem ceeb ntawm cov polymer.Tom qab ntawd cov silane tuaj yeem hnov ​​​​mob nrog dej vapor rau crosslink lub silane, tsim ib qho kev ruaj khov peb-dimensional siloxane qauv.Cov txheej txheem no tuaj yeem siv los hla kev sib txuas cov yas, polyethylene, thiab lwm yam organic resins, xws li acrylic resin thiab polyurethane roj hmab, txhawm rau txhim khu kev ruaj khov thiab tiv thaiv dej ntawm cov xim, txheej, thiab cov nplaum.
PSI-520 silane coupling tus neeg sawv cev yog siv rau cov organic dispersion kev kho mob ntawm fillers xws li MH / AH, kaolin, talc hmoov, thiab lwm yam. Nws kuj yog tsim rau MH / AH organic kev kho mob thiab daim ntawv thov nyob rau hauv halogen-dawb cable cov ntaub ntawv.Kev kho cov khoom siv hmoov tsis muaj hmoov av muaj hydrophobicity ntawm 98%, thiab cov dej sib cuag lub kaum sab xis ntawm cov organic inorganic hmoov yog ≥ 110 º.Cov hmoov inorganic tuaj yeem sib xyaw ua ke hauv cov organic polymers xws li cob, yas, thiab roj hmab, nrog rau cov yam ntxwv ntawm kev txhim kho cov kev ua tau zoo ntawm cov khoom ntim;Nce tus nqi ntawm oxygen limiting index (LOI);Ua kom lub hydrophobicity ntawm cov muab tub lim kuj tuaj yeem txhim kho cov khoom hluav taws xob (dielectric tas li tan, bulk hluav taws xob ρ D) Tom qab ntsib dej;Nce tus nqi ntawm cov muab tub lim ntxiv, thaum tseem muaj lub zog tensile siab thiab elongation thaum so;Txhim kho qhov kub tsis kam thiab txhim kho kev ua haujlwm
