Txhawm rau txiav aluminium alloy, tshwj xeeb alloy saw hniav yuav tsum tau xaiv. Feem ntau, cov khoom siv, ntau yam, thickness thiab tus naj npawb ntawm cov hniav ntawm saw hniav yog txhua yam yuav tsum tau.

Cov hniav tshwj xeeb zoo li cov txiav acrylic, khoom ntoo, plexiglass, thiab lwm yam yog siv tsis tau kiag li, vim tias cov nyhuv tsis zoo, thiab nws yuav raug puas tsuaj sai, uas 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 kev xav tau thaum xaiv, xws li cov hniav, qauv thiab lwm yam. Tom qab xaiv cov saw hlau, nco ntsoov xaiv cov saw hniav nrog cov hniav tiaj tus, tsis yog cov saw hlau txias, cov hlau nrawm nrawm lossis qee yam. 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 kev tsis sib xws xws li sab nraud ntawm cov saw hniav, aperture, thickness, tus naj npawb ntawm cov hniav, thiab lwm yam. Cov ntaub ntawv no muaj kev cuam tshuam zoo rau cov hniav. txiav nyhuv. Yog tias ib qho txuas raug xaiv tsis raug, qhov kev txiav txim siab ntawm ib feem yuav tsis txaus siab.

Piv txwv li, yog hais tias sab nraud ntawm lub sawb sawb yog loj heev, cov khoom siv yuav tsis tuaj yeem ntsia tau; Yog hais tias lub sab nraud txoj kab uas hla me me dhau, lub peev xwm txiav yuav tsis muaj zog, thiab nws yuav tsis raug txiav ib zaug. Raws li rau lub thickness ntawm cov saw hniav, nws muaj feem xyuam rau lub neej kev pab cuam. Yog hais tias nws yog thicker, tus nqi poob yuav raug txo, thiab lub neej ntawm saw saw yuav txuas ntxiv raws li. Txawm li cas los xij, yog tias nws tsis xav tau lub sijhawm ntev, nws tsis tas yuav xaiv ib qho tshwj xeeb tuab.
