Hydrophilic Fumed Silica
Gabatarwar Samfur
Fumed silica, ko pyrogenic silica, colloidal silicon dioxide, ne amorphous farin inorganic foda wanda yana da high takamaiman surface area, Nano-sikelin primary barbashi size da in mun gwada da high (a tsakanin silica kayayyakin) taro na surface silanol kungiyoyin. Ana iya canza kaddarorin silica fumed ta hanyar amsawa tare da waɗannan rukunin silanol.
Silica da ake samu na kasuwanci za a iya kasu kashi biyu: silica fumed silica da hydrophobic fumed silica. ana amfani da shi a matsayin wani muhimmin sashi a masana'antu da yawa kamar silicone roba, fenti da kuma robobi masana'antu.
Babban Halaye
1, mai kyau watsawa, mai kyau anti- nutse da adsorption.
2, A cikin roba na silicone: babban ƙarfafawa, tsayin daka mai tsayi, juriya mai kyau na abrasion, nuna gaskiya.
3, a cikin fenti: anti-sagging, anti-setling, inganta pigment kwanciyar hankali, inganta pigment watsawa, inganta fim adhesion, anti-lalata, hana ruwa, hana kumfa, taimako kwarara, inganta rheological iko.
4, Ana amfani da kowane launi na fenti (m, shafi, tawada) don inganta kwanciyar hankali na pigment, inganta tarwatsa pigment, inganta mannewar fim, anti-lalata, mai hana ruwa, anti-setling, anti-bubbling, musamman ga silicone roba ƙarfafa, m thixotropic wakili, anti-matsala wakili ga canza launi tsarin.
5, don tsarin ruwa na iya samun thickening, rheology iko, dakatarwa, anti-sagging da sauran ayyuka.
6, Domin m tsarin iya inganta inganta, lalacewa-resistant da sauransu.
7, Don tsarin foda zai iya inganta haɓakar kyauta kuma ya hana agglomeration da sauran tasiri. Hakanan za'a iya amfani dashi azaman babban filler mai aiki don roba na halitta da na roba, magani da kayan kwalliya.
