Hydrophobic Silica rau cov Khoom Yas
Silicon dioxide siv cov plastics hu ua silica plastics kev lag luam. Nws yog ib hom khoom siv nrog ib qhov chaw loj loj tom qab kho tshwj xeeb. Cov dawb cov roj dub siv tau cov ntaub ntawv sau ua cov polyethylene, polypropylene, polybutylene, epoxy resin thiab lwm yam yas, uas tuaj yeem txhim kho lub zog ntawm lub cev thiab hnav cov tshuaj tiv thaiv, nrog rau lub thermal stability ntawm hardness. Nruab nrab ntawm ob txheej ntawm yas zaj duab xis yog feem ntau nyuaj cais, thaum lub hnab yog nyuaj qhib, ces silica yog ib tug heev sab saum toj qhib. Thaum PVC siv los ua cov khoom siv hauv pem teb, yog tias muaj qee qhov muaj silica ntxiv, qhov nyuaj, elasticity, thermal denaturation thiab lwm cov khoom ntawm cov khoom tuaj yeem kho tau.
JS-682 ua cov organic organic hnav khaub ncaws nyob rau hauv cov kua tshuaj ua kua, cov hydrophobic precipitated silica peb tsim muaj cov yam ntxwv nram qab no: kev ua haujlwm siab, tsis muaj kev sib zog, ua kom zoo tshaj hauv cov khoom nruab nrog cev thiab cov kev sib txig zoo heev polymer. Thiab nws kuj muaj lub rheological muaj peev xwm kho lub ncov qaumteb qabteb, ntxiv cov pob tshab / ib nrab ntawm cov yam ntxwv rau roj hmab cov khoom.
