Hniav pwm yog qhov tseem ceeb ntawm cov kws kho kom zoo nkauj, thiab lawv cov kev tsim kho ncaj qha cuam tshuam nrog kev ua kom zoo nkauj tag nrho thiab ua kom zoo nkauj. Txhawm rau kom ntseeg tau tias kev teeb tsa cov tshuab ua kom zoo nkauj ua tau raws cov qauv tsim nyog, cov qauv tsim kev tsim kho yuav tsum tau ua rau nruj me ntsis rau.
Kev xaiv cov khoom thiab kev lees txais
Kev dai molding yog ua los ntawm ntau cov ntaub ntawv, suav nrog cov ntoo, plaster, pvc, thiab hlau. Cov khoom siv tsim nyog yuav tsum tau xaiv raws li kev siv. Ua ntej kev teeb tsa, soj ntsuam cov pwm rau saum npoo av, tawg}}} Tsis muaj kev zam txim siab, feem ntau, ± 1mm yog tso cai). Wood mouldings yuav tsum yaiab - Ua pov thawj kho, thaum hlau moulding yuav tsum muaj xeb {6} Ua pov thawj los xyuas kom meej ib puag ncig.
Substrate npaj
Lub substrate yuav tsum yog tiaj, ruaj, thiab pub dawb ntawm looseness lossis cov kab nrib pleb. Qhob lossis cov plaster substtrates yuav tsum qhuav (noo noo cov ntsiab lus tsawg dua los yog sib npaug ntawm 8%), thiab cov ntoo substrates yuav tsum yog tiaj thiab dawb ntawm warping. Yog hais tias lub substrate yog qhov tsis ncaj, thov cug lossis cement cug rau qib nws. Tom qab ziab, sandpaper kom du nws kom ntseeg tau tias tsis muaj qhov khoob lossis tsis sib xws hauv cov pwm tom qab kev teeb tsa.
Cov txheej txheem teeb tsa
Kev dai cov pwm yuav tsum muab nruab nrog cov nplaum muaj zog, ntsia hlau, lossis sib xyaw ntawm ob qho tib si. Siv cov yaum kom zoo nkauj, tswj kev sib ntsib ntawm 15-20cm ntawm cov ntsia hlau. Kho cov ntsia thawv qhov nrog cov khoom siv xim tib yam. Cov pob qij txha yuav tsum nruj, nrog pob qij txha ntawm 0.5mm lossis tsawg dua. Siv 45℃kab pheeb ces kaum pob qij txha ntawm cov ces kaum los xyuas kom meej cov kab ncaj thiab tsis muaj misalignment.
Zoo Txais
Tom qab ua tiav, tshuaj xyuas cov pwm rau lub zog thiab nruj, sib txuas, thiab cov paug thiab kev puas tsuaj. Kev sib txawv txawv yuav tsum tsawg dua lossis sib npaug ntawm 2 hli / m, thiab kab rov tav kev sib txawv yuav tsum tsawg dua lossis sib npaug rau 1mm / m. Thaum lub sij hawm lees txais, qhov kev ntsuas gauges tuaj yeem siv los tshawb xyuas qhov kev ua kom zoo nkauj rau kev kho kom zoo nkauj thiab kho cov phiaj xwm kho dua tshiab "(GB 50210).
Cov qauv kev tsim kho nruj me ntsis yog qhov tseem ceeb los ua kom lub loog thiab durability ntawm cov mouldive mouldive. Cov neeg thov yuav tsum ua raws li cov txheej txheem qauv kom ntseeg tau txhua kauj ruam raws li qhov yuav tsum tau ua, thaum kawg ua kom zoo nkauj zoo nkauj zoo nkauj.
