Tshwj xeeb saw hniav rau txiav acrylic, khoom ntoo, plexiglass, thiab lwm yam yog kiag li tsis siv, vim hais tias cov nyhuv yog twv yuav raug hu tsis zoo, thiab nws yuav puas sai sai, yog li nws tsis tsim nyog. Vim tias qhov tshwj xeeb pom hniav yog Ameslikas tsim raws li kev txiav cov yam ntxwv ntawm aluminium alloy hlau cov ntaub ntawv.
Ntawm lawv, muaj lwm yam yuav tsum tau thaum xaiv, uas yog hais txog tus naj npawb ntawm cov hniav, qauv thiab lwm yam. Tom qab xaiv cov saw hlau, nco ntsoov xaiv cov saw hniav nrog cov hniav tiaj tus, tsis txhob xaiv cov saw hlau txias, siab - ceev steel saw hniav lossis ib yam dab tsi. Yog tias koj xaiv qhov tsis ncaj ncees lawm thaum pib, koj yuav tsis muaj txiaj ntsig zoo tom qab.
Nyob rau tib lub sijhawm, hom saw hniav xaiv kuj tseem ceeb heev, feem ntau suav nrog cov khoom tsis xws li lub taub sab nraud, qhov taub, thickness, thiab cov hniav ntawm cov hniav. Cov ntaub ntawv no muaj txiaj ntsig zoo rau kev txiav cov nyhuv. Yog tias qhov txuas tsis raug raug xaiv, qhov cuam tshuam ntawm ib feem yuav tsis txaus siab.
Piv txwv li, yog hais tias sab nraud ntawm cov saw hniav uas xaiv loj heev, cov khoom siv yuav tsis raug ntsia; Yog hais tias lub sab nraud yog me me, lub peev xwm txiav yuav tsis muaj zog, thiab nws yuav raug txiav tsis tu ncua ntawm ib zaug. Raws li rau lub thickness ntawm cov saw hniav, nws muaj feem xyuam rau lub neej kev pab cuam. Yog tias nws yog tuab dua, qhov poob qis yuav raug txo, thiab lub neej kev pab cuam ntawm sawb yuav txuas ntxiv raws li. Txawm li cas los xij, yog tias nws tsis tas yuav tsum tau ntev, nws tsis tas yuav xaiv ib qho tshwj xeeb tuab.
