Kev khiav hauj lwm txheej txheem (raws li qhia hauv daim duab):
Kev npaj khoom:
1.1 Npaj cov khoom kom zoo zoo ntawm lub tais hlau.
Kho lub tshuab nqus tsev Impregnation Solution:
1.2 Kho qhov concentration ntawm cov kua roj vanish rau 0.915±0.04.
Vacuum Impregnation txheej txheem:
1.3 Muab lub tais nrog cov khoom npaj rau hauv lub tank impregnation.
1.4 Qhib lub tshuab nqus tsev impregnation thiab twj tso kua mis mus rau 40-50 cm / Kg. Tom qab ntawd, ntxiv cov kua roj vanish thiab txuas ntxiv mus rau 65-75 cm / Kg. Cov txheej txheem nqus tsev yuav tsum ua ntu zus, rhuav tshem lub tshuab nqus tsev 3-5 zaug. Ua lub impregnation rau 10-15 feeb kom txog thaum tsis muaj cua npuas dhau los ntawm cov khoom.
De-Vacuuming thiab ziab:
1.5 Tso lub tshuab nqus tsev, tshem tawm cov kua roj vanish, thiab rov tso lub tshuab nqus tsev mus rau 65-75 cm / Kg ib zaug ntxiv. Tso lub tshuab nqus tsev, thiab tom qab cov khoom qhuav me ntsis, tshem tawm thiab muab tso rau ntawm lub tshuab ziab khaub ncaws kom qhuav.
1.6 Lim kom qhuav rau yam tsawg kawg 10 feeb kom txog thaum tsis muaj cov kua roj vanish ntws los ntawm cov khoom.
Txoj kev Curing:
1.7 Preheat qhov cub kom 80 degree thiab khaws cia rau 1 teev. Tom qab ntawd, kho qhov kub ntawm 100 degrees thiab ci rau 2 teev. Thaum kawg, teem lub qhov cub rau 110 degree thiab ci rau 4 teev ntxiv. Tom qab ci, tshuaj xyuas cov khoom.
Cua txias:
1.8 Tshem cov khoom tawm ntawm qhov cub.
1.9 Siv lub kiv cua kom ceev cov txheej txheem txias.
Cov kauj ruam kawg:
1.10 Npaj cov khoom ntawm lub tais thiab xa mus rau cov kab ntau lawm.
Cov txheej txheem no xyuas kom meej impregnation thiab kho cov khoom thaum tswj kev tswj kom zoo thoob plaws hauv cov txheej txheem.
