1, ntxuav cov seem uas seem ntab, roj thiab lwm cov khib nyiab thiab cov khoom seem ntawm lub pob zeb ua vaj tse, thiab lwm yam.
2. Tshem tawm cov pob zeb ua vaj tse, kev sib txuas, cov hollows, thiab lwm yam uas cais lub ru tsev, thiab kho lawv dua.
3. Nws yuav tsum tau hais tias lub deg flatness sib txawv ntawm cov ceramic fiber board yuav tsum tsis txhob ntau tshaj 4nm thaum sib txuas, thiab yog hais tias nws yog tsis kam, polish lub nto moo pob zeb nto thiab kho lub concave ib feem (plaster nrog 1: 2.5 cement mortar thaum lub kho thickness ntau tshaj 6 hli, thiab siv polymer bonding mortar thaum kho thickness tsawg dua 6 hli); Txhawm rau kom ntseeg tau tias qhov flatness ntawm tag nrho cov phab ntsa yog nyob rau hauv 4 hli, thiab lub kaum sab xis ntawm yin thiab yang yog square thiab du.
4. mortar siv nyob rau hauv kev tsim kho yog muab faib ua tshwj xeeb sib txuas mortar thiab tshwj xeeb nplaum rau saum npoo kub.
5. Qhov hnyav piv ntawm kev sib tov sib xyaw mortar yog dej: mortar =1.5, thiab lub sij hawm sib tov tsis pub tsawg tshaj 5min thaum ntxiv dej. Qhov sib tov yuav tsum txaus thiab sib xws, nrog rau qhov sib xws thiab qee qhov viscosity.
6. Tom qab lub mortar tau npaj lawm, nws yuav tsum tau tso tseg kom sawv ntsug li 5 feeb. Do dua ua ntej siv. Cov tshuaj sib tov yuav tsum siv li ntawm 1 teev.
7. Txhawm rau txhim kho qhov kev sib khi ntawm lub rooj tsavxwm extruded thiab cov khoom sib txuas, ua ntej pasting fiberboard.
