Don fahimtar hanyar lissafi na yawa na refractory castable, menene ramin iska?
1. Akwai nau'ikan pores iri uku:
1. An rufe ɗaya gefe kuma ana sadarwa da ɗayan waje, wanda ake kira buɗaɗɗen pore.
2. An rufe murfin da aka rufe a cikin samfurin kuma ba a haɗa shi da duniyar waje ba.
3. Ana kiran ta ramukan ta ramuka.
Jimlar porosity, wato porosity na gaskiya, yana nufin adadin yawan adadin pores a cikin jimlar samfurin;Gabaɗaya, ramin ramin yana haɗuwa tare da buɗaɗɗen ramin, kuma ramin da aka rufe ya ragu kuma yana da wahala a auna kai tsaye.Saboda haka, porosity yana bayyana ta hanyar buɗaɗɗen porosity, wato, porosity na fili.Bayyanar porosity yana nufin adadin jimlar adadin buɗaɗɗen ramuka a cikin samfurin zuwa jimillar ƙarar samfurin.
Matsakaicin girma yana nufin rabon juzu'in busashen samfurin zuwa jimillar ƙarar sa, wato, rabon ƙarar jujjuyawar jikin da aka iya samu zuwa jimillar ƙarar sa, wanda aka bayyana a cikin Kg/m3 ko g/cm3.Bayyanar porosity da yawa mai yawa ɗaya ne daga cikin tushe don sarrafa yawan simintin da aka yi amfani da shi a cikin gini.Ana iya auna ma'auni guda biyu na aiki tare da samfurin iri ɗaya.Masu biyowa su ne ƙaƙƙarfan yawa da bayyananniyar ƙaƙƙarfan ƙaƙƙarfan simintin da aka saba amfani da su.
