Tus nqi ntawm cov khoom siv txhuas sib txawv hauv tag nrho kev lag luam, yog li dab tsi yog qhov laj thawj uas txiav txim siab tus nqi ntawm cov khoom siv txhuas? Niaj hnub no, ua tus tsim khoom zoo hauv sab qab teb sab hnub poob Suav teb, kev lag luam txhuas tshwj xeeb yuav raug piav qhia kom ntxaws rau feem ntau ntawm cov neeg siv!
Tus nqi ntawm cov khoom siv aluminium profile feem ntau yog txiav txim siab los ntawm kev xaiv cov khoom siv raw thiab cov txheej txheem ua cov khoom.
Kev xaiv cov khoom siv raw muaj feem cuam tshuam loj heev rau tus nqi ntawm cov khoom siv aluminium. Qhov zoo ntawm cov khoom siv aluminium siab dua, tus nqi yuav siab dua. Piv txwv li, ib daim ces kaum: daim ces kaum uas siv cov khoom siv raw zoo muaj qhov nyuaj siab thiab ci ntsa iab, thiab nws tsis yooj yim tawg lossis tawg. Cov daim ces kaum uas siv cov khoom siv raw qis dua muaj lub zog carat qis thiab feem ntau tawg lossis tawg.
Tsis tas li ntawd xwb, cov txheej txheem thiab thev naus laus zis ntawm kev ua cov khoom kuj yog ib qho tseem ceeb los txiav txim siab tus nqi ntawm cov khoom siv txhuas profile. Cov thev naus laus zis zoo tuaj yeem ua kom du thiab lub neej ua haujlwm ntawm qhov chaw ntawm cov khoom, yog li tus nqi yuav siab dua. Txawm li cas los xij, cov khoom siv txhuas profile uas siv thev naus laus zis tsis zoo tsis tsuas yog muaj lub neej ua haujlwm luv luv xwb, tab sis kuj muaj qhov chaw ntxhib, txawm tias burrs lossis notches, thiab qhov cuam tshuam tag nrho tsis zoo heev. Yog li ntawd, tus nqi yuav qis dua li cov khoom siv tes ua zoo.
