Nyob rau hauv cov txheej txheem, cov ntaub ntawv raw cov ntaub ntawv rau zus tau tej cov unburned bricks ua los ntawm lub unburned cib tshuab yog nplua nuj, thiab tam sim no cov kev tsim kho cov khib nyiab ntau ntxiv muab ib tug txhim khu kev qha raw khoom guarantee rau lub unburned bricks. Lub tshuab thiab txheej txheem theem ntawm Honcha tsis raug rho tawm haujlwm cib tshuab yog nyob rau theem ua hauv Suav teb. Raws li peb paub, cov khoom ua tau zoo nyob ntawm cov yam ntxwv ntawm cov khoom siv raw thiab cov tshuab tsim. Raws li kev soj ntsuam ntawm lub teb chaws phab ntsa thiab lub ru tsev cov ntaub ntawv zoo soj ntsuam qhov chaw, cov txheej txheem kev ua tau zoo ntawm lub cib ua los ntawm cov uas tsis yog raug rho tawm haujlwm cib tshuab yog siab tshaj li cov tsoos av nplaum liab cib, lub peev xwm thiab dej nqus tau zoo dua li cov qhob cib zoo tib yam, thiab qhuav shrinkage thiab thermal conductivity yog me dua li cov khoom siv pob zeb zoo tib yam. Nyob rau hauv luv luv, ntau yam kev xeem cov ntaub ntawv qhia tau hais tias lub compressive structural kev ua tau zoo ntawm unburned cib yog zoo dua li cov tsoos liab cib. Nws tuaj yeem tiv taus qhov kev sim ntawm keeb kwm thiab lub sijhawm, thiab muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig.
