Cov khoom siv tseem ceeb ntawm cov hlau nruas yog hlau daim hlau. Feem ntau, cov phaj steel yuav tsum muaj qhov tiaj tiaj, tsis tshua nruj, cov ntsiab lus me me, thiab cov tuab tuab. Cov khoom siv yuav tsum tau tsim cov hlau nruas muaj xws li cov ntsaws ruaj ruaj, gaskets, ntsaws ruaj ruaj, thiab lo txheej. Crimping sealant yuav tsum muaj qhov zoo elasticity, muaj zog adhesion, ntau qhov kev kho kom zoo, kev siv tshuaj zoo thiab kev ua haujlwm.
Lub tiaj nyom hauv tshuab technical koom nrog kev tsim cov hlau nruas yog dav heev. Feem ntau, cov txheej txheem hauv qab no yuav tsum muaj: daim ntawv tsis muaj txheej txheem thiab qib ing txiav thiab seem ing chim vuam vuam → thoob vias vias → thoob lub cev → ntim cov khoom ntim thiab txuam bottom lub thawv hauv qab npog tsim thiab prerolling → kev kho saum npoo → sab hauv txau cov tshuaj tsuag xim rau sab nraud nto → sau.
Lub cev nruas hlau tau siv los ua cov xim ntim xim ntim ntim rau ntau tshaj 100 xyoo. Hauv kev siv ntau xyoo, hlau nruas tau tsim rau hauv qhov ua tiav txhij raws li cov qauv khoom thiab kev ua haujlwm tshwj xeeb. Txawm hais tias cov khoom siv hlau ntim tau tseem hloov zuj zus ntxiv mus raws li cov qauv, qhov kev tsim qauv yooj yim tseem zoo li qub. Kev paub tab thiab kev txhawb nqa ua tiav cov kab ntau lawm yog ib qho kev nyuaj rau txoj kev txhim kho ntawm kev ntim cov ntawv ntim txuas ntxiv.
Txawm li cas los xij, steel nruas tseem muaj qee yam tsis zoo. Piv txwv li, hlau nruas yog tsuas yog hloov nruas, thiab qee lub nruas me me muaj cov nyom sib dhos. Txawm li cas los xij, cov duab ntawm cov thoob khib nyiab yog qhov sib txuam, thiab nws yog qhov nyuaj los ua cov qauv ntau dua. Hom sib txawv ntawm cov tsho tiv no tsis yooj yim rau kev tsim cov ntim sib txawv. Txawm hais tias kev txhim kho tshuab luam ntawv tuaj yeem luam tawm cov qauv zoo nkauj nyob rau saum npoo ntawm cov pob zeb steel, feem ntau ntawm cov khoom siv hlau tau muaj cov nplawm rau ntawm lub thoob, uas cuam tshuam cov qib zoo ntawm cov qauv thiab pom cov nyhuv. Ib qho ntxiv, thaum tab tom siv, nws nyuaj rau cov xim muaj hlau kom siv ib zaug ib chim. Yog li ntawd, cov xim ntim yuav tsum tau sib khi zoo dua. Kev sib khi ntawm lub hau ntawm lub hau qhib lub thoob ntsaws ruaj ruaj yog qhov nruab nrab, uas tseem yog ib qho ntawm qhov tsis txaus ntseeg qhov chaw tuag ntawm lub thoob steel.https: //www.fhpails.com/
