Shin silicone na samfuran filastik ne?
Silica gel abu ne na colloidal da aka yi da silicate, wanda galibi ya ƙunshi silica, ruwa da silicone monomers.Gel na silica yana da halaye na haɓakar haɓaka, babban nuna gaskiya, babban kwanciyar hankali da juriya mai zafi, don haka ana amfani da shi sosai a fannoni daban-daban.Kodayake gel silica yana kama da filastik a wasu kaddarorin, ba ya cikin samfuran filastik daga mahangar tsarin sinadarai da tsarin shiri.
Da farko, akwai bambance-bambance a bayyane a cikin tsarin sinadarai na silicone da filastik.Filastik gabaɗaya sun ƙunshi manyan mahadi na ƙwayoyin cuta, waɗanda ke samar da dogayen ƙwayoyin sarƙoƙi ta hanyar polymerization, suna samar da tsari mai ci gaba da daidaituwa.Gel ɗin silica ya ƙunshi nau'ikan silico-oxygen, wanda ke samar da tsarin hanyar sadarwa.Tsarin na musamman na haɗin siliki-oxygen ya sa gel silica yana da halaye na kayan colloidal mai wuya, yayin da robobi yawanci kayan colloidal masu laushi ne.
Abu na biyu, akwai kuma bambance-bambance a bayyane tsakanin gel silica da filastik a cikin tsarin shirye-shiryen.Ana gudanar da shirye-shiryen robobi ta hanyar narkewa mai zafi, extrusion, gyare-gyaren allura da sauran hanyoyin sarrafawa don samar da samfuran siffofi da girma dabam dabam.A shirye-shiryen na silica gel ne yafi za'ayi ta hanyar gel dauki na hydrated colloid, wanda bukatar sarrafa dauki yanayi, rabo da pH darajar da sauran sigogi, sa'an nan ta bushewa da calcination da sauran matakai, sabõda haka, shi Forms silico- oxygen bond cibiyar sadarwa, kuma a karshe shirya cikin silicone kayayyakin.
Bugu da ƙari, akwai wasu bambance-bambance tsakanin silicone da filastik a yanayi da amfani.Abubuwan da aka saba amfani da su na robobi sune kariya mai kyau, ƙarfin injiniya da kwanciyar hankali na sinadarai, da dai sauransu, waɗanda aka yi amfani da su sosai a rayuwar yau da kullum, samar da masana'antu da filayen lantarki.Silica gel yana da kyakkyawan kwanciyar hankali na thermal, juriya da rashin ƙarfi na sinadarai kuma ana amfani dashi sosai a abinci, likitanci, lantarki da jirgin sama da sauran fannoni.Aikace-aikacen gama gari na samfuran silicone sun haɗa da bakin kwalban siliki, mundayen siliki da hatimin siliki.
A taƙaice, kodayake gel ɗin silica yana kama da filastik a cikin wasu kaddarorin, akwai bambance-bambance a bayyane tsakanin silica gel da filastik dangane da tsarin sinadarai, tsarin shirye-shirye da filayen aikace-aikacen.Silica gel wani abu ne na musamman na colloidal tare da kayan aikinsa na musamman da ƙimar aikace-aikacen.Don haka, silicone ba ya cikin samfuran filastik.
