Nrog rau kev siv ntau ntawm mortar, qhov zoo thiab ruaj khov ntawm mortar tuaj yeem lav tau zoo. Txawm li cas los xij, vim tias cov tshuaj khib nyiab qhuav yog ua tiav ncaj qha thiab tsim los ntawm lub Hoobkas, tus nqi yuav siab dua ntawm cov khoom siv raw. Yog tias peb txuas ntxiv siv phau ntawv plastering ntawm qhov chaw, nws yuav tsis muaj kev sib tw, ntxiv rau muaj ntau lub nroog thawj zaug hauv ntiaj teb uas muaj kev tsis txaus ntawm cov neeg ua haujlwm tsiv teb tsaws chaw. Qhov teeb meem no ncaj qha qhia txog kev nce nqi zog ntawm kev tsim kho, yog li nws kuj txhawb kev sib xyaw ntawm kev tsim kho tshuab thiab cov tshuaj khib nyiab qhuav. Hnub no wb tham txogHydroxypropyl methylcellulose yog ib qho khoom siv zooHPMCnyob rau hauv ib co kev siv tshuab tshuaj tsuag mortar.
Cia peb tham txog tag nrho cov txheej txheem kev tsim kho ntawm lub tshuab txau mortar: sib tov, siv thiab txau. Ua ntej ntawm tag nrho cov, peb yuav tsum xyuas kom meej tias nyob rau hauv lub hauv paus ntawm tsim nyog formula thiab raw khoom clearance, lub compound additive ntawm lub tshuab-blasted mortar mas plays lub luag hauj lwm ntawm optimizing qhov zoo ntawm mortar, uas yog tsuas yog los txhim kho cov kev ua tau zoo ntawm mortar. Yog li ntawd, nyob rau hauv ib txwm muaj xwm txheej, cov khoom sib xyaw ua ke rau lub tshuab-txhaj tshuaj mortar yog tsim los ntawm cov dej tuav tus neeg saib xyuas thiab cov twj tso kua mis. Hydroxypropyl methylcellulose tuaj yeem tsis tsuas yog ua kom cov viscosity ntawm cov mortar, tab sis kuj txhim kho cov kua dej ntawm cov mortar, yog li txo qhov tshwm sim ntawm kev sib cais thiab los ntshav. Thaum cov neeg ua haujlwm tsim cov khoom siv ntxiv rau lub tshuab-blasted mortar, nws yog ib qho tsim nyog yuav tsum tau ntxiv qee cov stabilizers nyob rau lub sijhawm, uas tseem yuav ua rau qeeb delamination ntawm mortar.
Piv nrog rau cov tshuaj mortar sib xyaw rau ntawm qhov chaw, lub tshuab tshuaj tsuag mortar feem ntau yog los ntawm kev qhia txog hydroxypropyl methyl cellulose ether, uas ua lub luag haujlwm hauv kev ua kom zoo ntawm cov mortar thiab ncaj qha txhawb kev ua haujlwm ntawm cov tshuaj khib nyiab tshiab. Cov dej tuav tus nqi kuj tseem yuav siab dua thiab muaj kev ua haujlwm zoo. Lub ntsiab lus zoo tshaj plaws yog qhov kev tsim kho kev ua haujlwm siab, qhov zoo ntawm cov tshuaj khib tom qab molding yog qhov zoo, thiab qhov tshwm sim ntawm hollowing thiab cracking yuav txo tau zoo.
