Brick Weight Weight Clay Insulation An yi shi da yumɓun wuta a matsayin ɗanyen abu da yumɓun filastik azaman wakili mai ɗauri sannan ƙara madaidaicin mai ƙonewa ko kumfa ta hanyar harbi. yumbu rufi tubalan bayyananne porosity ne high game da 40 ~ 85% da girma yawa ne kasa da 1.5 g/cm3. Ana amfani da tubalin wuta mai rufin yumbu a matsayin kayan rufewa a cikin kiln masana'antu don rage asarar zafi, adana makamashi da sauƙaƙe ingancin kayan aikin zafi.
Ana samar da Brick Weight Clay Insulation Brick daga yumbu mai tsabta na wuta da ɗaure, ta hanyar sintiri ta yanayin zafi. Tubalan rufin yumbu sune bulogin rufin ƙarancin farashi tare da babban aiki. Babban abũbuwan amfãni na lãka rufi toshe ne high refractoriness a karkashin kaya, low line fadada coefficients, mai kyau thermal girgiza juriya da kuma karfi ikon tsayayya da yashwa. Wanne an yi shi da kayan wuta na sama na gida a ƙarƙashin babban zafin jiki bisa ga ƙa'idodin ƙasa mai ɗorewa, wanda ya mallaki ko da yawa mai yawa, ƙarfi mai ƙarfi, ƙarancin ƙarancin zafi da ƙarancin ƙazanta.
