Cement extrusion yog txheej txheem nyuaj siv los tsim cov khoom siv xws li cov phaj hauv paus, clapboards, thiab cib, haum rau kev siv sab hauv thiab sab nrauv, nrog rau lub suab rwb thaiv tsev.Cov ntaub ntawv no yog tsim los ntawm kev sib xyaw ntawm cov cement, aggregates, fibers, thiab dej.Nrog asbestos tam sim no txwv tsis pub los ntawm txoj cai, kev siv cov cement extruded boards raws li kev hloov pauv tau dhau los ua qhov tseem ceeb.Hloov kho thiab tsis hloov pauv cellulose ether qib ntawm MHEC thiab MHPC tuaj yeem muab ntxiv rau cov mortars qhuav los txhim kho kev ua haujlwm ntawm cov cement sib tov, txhim kho kev ua haujlwm thiab ua rau cov khoom muaj zog, ruaj khov dua.
Cellulose ether yog cov khoom muaj txiaj ntsig hauv cov cement extrusion vim nws cov txiaj ntsig ntau yam.Nws cov khoom adhesion siab thiab lubricity txhim khu kev ua haujlwm ntawm cov khoom extruded, thaum tseem txhim kho ntsuab lub zog thiab txhawb nqa dej thiab kho cov teebmeem, ua rau muaj txiaj ntsig ntau dua.Tsis tas li ntawd, nws lubricity thiab plasticity ua rau nws xaiv zoo heev rau ceramic molding.Tsis tas li ntawd, cellulose ether tsim cov khoom siv ceramic nrog kev ntxhib los mos thiab du nto vim nws cov ntsiab lus tsawg tsawg.Zuag qhia tag nrho, kev siv cellulose ether hauv cov cement extrusion muaj ntau cov txiaj ntsig uas tuaj yeem txhim kho kev ua tau zoo thiab zoo ntawm cov txheej txheem tsim khoom.
