Txhawm rau kom ruaj ntseg cov khoom siv, siv lub thaiv sab; ua ntej ruaj ntseg lub thaiv qis dua kom tiv thaiv cov khoom siv kom tsis txhob plam; ciam teb ntawm cov khoom siv yog 20-30 hli ntawm qhov kawg ntawm keel. Txhawm rau txiav txim siab qhov sib npaug ntawm cov khoom siv, ob tus neeg yuav tsum ua haujlwm ua ke thaum lub sijhawm kho thiab thaum siv tus pas ntsuas theem lossis rub txoj kab.
Kev Txhim Kho Cov Ru Tsev Pobzeb
1. Ntsuas qhov chaw teeb tsa ntawm lub ru tsev rau lub hauv paus vuas ceramic raws li qhov ntev qhia hauv cov duab kos, tshem tawm cov vuas uas tau teeb tsa ua ntej, thiab siv cov ntsia hlau ntoo los khi lub hauv paus rau lub ru tsev purlin (sim kho tag nrho cov hauv paus ib zaug; yog tias muaj tej yam tsis zoo, kho ob kab ntawm keel kom pab nrog kev teeb tsa);
2. Txhim kho lub keel, kho qhov sib nrug ntawm keel raws li qhov chaw uas cov qhov sib txuas ntawm cov khoom siv nyob rau hauv kom xaiv lub keel thiab cov qhov sib txuas ruaj khov rau hauv ± 100 hli; siv cov txiv ntoo profiled ntawm lub beam tso rau hauv lub hauv paus vuas ceramic los hloov kho qhov chaw ntawm ciam teb siv cov ntsia hlau hexagonal nruj;
3. Kev teeb tsa cov khoom sib txuas: Cov khoom sib txuas thawj zaug yuav raug muab tso rau ntawm sab ntawm txoj hlua qhia. Siv tus pas ntsuas, xyuas kom meej tias qhov sib npaug ntawm cov khoom sib txuas ntsuas tsawg kawg 20 hli ntawm sab ntawm txoj hlua qhia. Tom ntej no, siv sab ntawm lub thaiv siab los ruaj ntseg kev teeb tsa ntawm cov khoom sib txuas thib ob. Thaum kawg, siv lub thaiv siab los nruj lub thaiv siab siv txoj kev kho kab pheeb ces kaum. Cov khoom seem yuav raug teeb tsa rau lwm qhov. Kev teeb tsa cov khoom seem yog ua tiav raws li kev txiav txim.
