Cov Hlau Carbon Hlau Qwsyog cov khoom siv hlau kub dov uas muab los ua daim ntawv coil yooj yim rau kev thauj mus los, khaws cia, thiab tuav. Tsis zoo li cov hlau ncaj, cov hlau coiled tuaj yeem muab sib dhos ua ke tau zoo, txuag kev thauj mus los thiab chaw cia khoom. Piv txwv li, ib lub hlau 8mm tuaj yeem coiled rau hauv ib lub disc kwv yees li 1.2-1.5 meters hauv txoj kab uas hla thiab hnyav ntau pua kilograms, zoo tagnrho rau kev faib khoom lag luam loj.
Ib qho ntawm cov txiaj ntsig loj tshaj plaws ntawmkub dov hlau pas nrigyog nws qhov kev siv tshuab zoo heev. Txawm yog cov hlau uas muaj carbon tsawg, cov hlau uas muaj carbon ntau, lossis cov hlau sib xyaw, cov hlau hlau muaj cov yas zoo thiab tawv, ua rau nws yooj yim rau kev tsim. Koj tuaj yeem rub nws txias rau hauv cov hlau hlau, ncaj thiab txiav nws ua cov ntsia hlau lossis cov rivets, lossis braid nws rau hauv cov hlau mesh thiab cov hlua hlau. Yog li ntawd, cov hlau hlau yog siv dav hauv kev tsim kho, tshuab, tsheb, thiab kev lag luam tsim khoom hlau.
Qhov zoo yog qhov tseem ceeb, thiab niaj hnubCov Hlau Hlaucov mills tau tsim los rau lub hom phiaj no. Kev tswj hwm kev kam rau siab ntawm txoj kab uas hla (feem ntau yog nyob hauv ± 0.1 hli) ua kom muaj qhov ntev ntawm cov kauj sib xws. Kev tswj hwm kev txias thiab kev kho qhov chaw tsim cov nplaim du, qis-oxide-scale, txo qhov xav tau kev polishing tom qab. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov hlau ua los ntawm cov hlau uas siv hauv cov caij nplooj ntoos hlav, vim tias qhov zoo ntawm qhov chaw cuam tshuam ncaj qha rau lawv lub neej qaug zog.
