Nws feem ntau tau ua rau hauv cov laug cam, cib thiab cov vuas yeeb. Qhov nyiaj ntau tshaj plaws ntawm kev ua haujlwm zoo ib yam li ntawm cov cement yog 600 degree, thiab ntawm cov alumina siab yog 800 degree.
Dej iav perlite yog cov khoom lag luam nrog qee cov duab ua los ntawm kev sib sau ua ke, tom qab sib tov, moulding, roing, ci lossis kho. Muaj ntau ntau yam kev nthuav dav perlite cov khoom lag luam. Tam sim no, cov khoom lag luam hauv tsev tshwj xeeb yog suav nrog cov khoom lag luam nthuav dav, cov iav dej nthuav dav perlite cov khoom lag luam thiab phosphate nthuav dav perlite cov khoom lag luam.
Dej iav perlite yog lub teeb ci rwb thaiv tsev cov khoom siv nrog qee cov duab ua los ntawm cov khoom siv thoob plaws. Kev ceev me me, kev ua tau zoo rwb thaiv tsev, cov tshuaj ruaj khov. Tsawg noo noo nqus muaj peev xwm, hluav taws xob hluav taws xob, thiab lub suab zoo nqus tau kev ua tau zoo. Feem ntau, tsim nyog binders (dej iav, txhuas phosphate, thiab lwm yam) tau siv nrog qee qhov teeb tsa cov khoom kom tiav. Dav siv dav siv hauv kev tsim kho, tshuaj lom neeg, roj av, hluav taws xob, kev thauj mus los thiab cov chaw ua liaj ua teb. Nws yog ib qho khoom muaj txiaj ntsig heev.
Dej iav perlite yog cov khoom rwb thaiv tsev ua los ntawm cov dej iav (na2o.nsio2) raws li cov neeg sawv cev ntawm kev sib xyaw, moulding, kho thiab tua neeg. Nws muaj cov rwb thaiv tsev tshav kub kub thiab cov suab nqus cov khoom.
Dej iav perlite cov khoom lag luam, ceev tsawg dua 3 {{2} {{4 4 4 4; Compressive zog tsis tsawg tshaj li 0. 5mpa; Thermal conductivity ntawm chav tsev kub yog 0.056 ~ 0.065W / (MK). Cov nplaim yog greyish dawb; Coj mus rhaub nrog cov ntiv tes sib koom ua ke, muaj suab nrov; Pinch los ntawm txhais tes, tsis yooj yim rau kev zuaj. Tab sis nws tsis tuaj yeem tiv thaiv ntog los ntawm qhov siab. Nws yuav tsis plam tom qab raug xau dej rau lub sijhawm luv.
