Spiral tube nto kho txoj kev:
Yog vim li cas vim li cas lub kauv raj hu ua lub npe no yog vim hais tias nws cov tsos zoo li muaj ib tug kauv qauv. Thaum tsim khoom, nws siv cov qauv qis-carbon steel lossis cov hlau tsis tshua muaj hlau ua cov khoom siv, thiab tom qab ntawd los ntawm qee lub kaum sab xis Ntau lawm, txuas rau hauv cov txheej txheem vuam kawg. Tom ntej no, cia peb tham txog cov txheej txheem twg yog thaum cuam tshuam nrog lub ntsej muag ntawm cov kauv raj.
Ua ntej, siv cov txheej txheem ntawm kev ntxuav ncaj qha, siv qee cov kuab tshuaj, emulsions, thiab lwm yam los ntxuav cov yeeb nkab sab nraud, uas tuaj yeem ua tiav lub luag haujlwm ntawm kev ntxuav cov plua plav, roj thiab lwm yam organic teeb meem, tab sis ntxaum xeb, txheej oxidation tsis tuaj yeem. huv si.
Yog li ntawd, thaum koj muab lub raj acoustic thiab muab tso rau hauv lub tawb muaj zog, koj yuav tsum tau them sai sai rau kev kho nws ntawm lub ntsiab band raws li qhov loj me, thiab rau ib feem ntawm lub tawb steel -free tawb, ntxiv peb steel tuav. qhov chaw nres nkoj ntawm lub raj acoustic mus rau qhov chaw nres nkoj ntawm lub suab raj. Thiab tswj qhov kev ncua deb ntawm cov khoom siv no, thiab thaum koj cuam tshuam nrog ntu thib ob ntawm lub tawb steel, koj kuj yuav tsum tau ntxig cov ntaub ntawv sib txawv ntawm qhov ntev ntawm qhov chaw, kaw nws, thiab tom qab ntawd hla cov hlau hlau los ntawm cov khoom siv yeeb nkab. Nyob rau hauv lub lifting nplhaib, cov neeg ua hauj lwm yuav tsum tau them sai sai rau qhov kev faib ua feem nyob rau hauv tus txheej txheem kom tsis txhob muaj ntau dhau ntawm nws.
