Silica mai siffar ruwa
Gabatarwar Samfuri
Silica mai ƙura, ko silica mai pyrogenic, colloidal silicon dioxide, foda ne mai launin fari mara tsari wanda ke da babban yanki na saman, girman babban barbashi na nano da kuma yawan ƙungiyoyin silanol na saman (a tsakanin samfuran silanol). Ana iya canza halayen silica mai ƙura ta hanyar sinadarai ta hanyar amsawa da waɗannan ƙungiyoyin silanol.
Ana iya raba silica mai hayaƙi da ake samu a kasuwa zuwa ƙungiyoyi biyu: silica mai hayaƙi da kuma .... Ana amfani da shi sosai a matsayin muhimmin sinadari a masana'antu da dama kamar su robar silicone, fenti da kuma masana'antar robobi.
Babban Halaye
1, watsawa mai kyau, mai kyau wajen hana nutsewa da kuma shawa.
2, A cikin robar silicone: ƙarfafawa mai ƙarfi, juriyar hawaye mai ƙarfi, juriyar gogewa mai kyau, bayyananne mai kyau.
3, a cikin fenti: hana lanƙwasawa, hana daidaitawa, inganta daidaiton launin fata, inganta watsawar launin fata, inganta mannewa na fim, hana lalatawa, hana ruwa shiga, hana kumfa, taimakawa wajen kwarara, haɓaka sarrafa rheological.
4, Yana aiki ga kowane Layer na fenti (mai mannewa, shafi, tawada) don inganta daidaiton launi, inganta watsawar launi, inganta mannewar fim, hana lalatawa, hana ruwa, hana daidaitawa, hana kumfa, musamman don ƙarfafa robar silicone, wakili mai mannewa na thixotropic, wakili mai hana daidaitawa don tsarin launi.
5, domin tsarin ruwa zai iya samun kauri, sarrafa rheology, dakatarwa, hana sagging da sauran ayyuka.
6, Domin tsarin mai ƙarfi zai iya inganta haɓakawa, juriya ga lalacewa da sauransu.
7, Domin tsarin foda zai iya inganta kwararar iska kyauta da kuma hana haɗuwa da sauran tasirin. Hakanan ana iya amfani da shi azaman cika mai aiki mai ƙarfi don roba na halitta da na roba, magunguna da kayan kwalliya.
