Tsis ntev los no, kuv tau tham nrog ntau tus neeg siv khoom uas ua haujlwm nrog kev tsim kho kav dej. Kuv pom thaum xaiv cov kav dej sab hauv lawv ib txwm ntxhov siab rau lo lus nug no: Cov Yeeb Nkab Polyurethane Lined thiabCov yeeb nkab polypropylene, qhov twg zoo dua? Tag nrho cov ntaub ntawv tseem ceeb yog Spiral Seam Welded Pipe, tab sis cov ntaub ntawv sab hauv yog txawv, thiab kev ua tau zoo thiab tus nqi sib txawv heev.
Niaj hnub no, los ntawm kev coj qhov teeb meem tiag tiag ntawm Cangzhou Spiral Steel Pipe Factory ua piv txwv, kuv yuav piav qhia qhov teeb meem no kom meej.
Cia peb pib nrog lub substrate. Qhov no yog lub hauv paus.
Txawm hais tias sab hauv yog ua los ntawm PU lossis PP, cov khoom siv hauv paus yeej ib txwmKauv Seam Welded Yeeb NkabMuaj ntau lub chaw tsim khoom hauv Cangzhou uas tsim cov khoom no, tab sis tsuas yog Cangzhou Spiral Steel Pipes Group Co., Ltd. thiaj li ua tiav qhov loj. Lub tuam txhab no tau tsim tsa xyoo 1993, npog thaj tsam ntawm 350,000 square meters hauv Cangzhou, nrog tag nrho cov cuab tam ntawm 680 lab yuan thiab 680 tus neeg ua haujlwm. Nws tuaj yeem tsim tau 400,000 tons ntawm cov kav hlau kauv ib xyoos, nrog rau cov nqi tso tawm ntawm 1.8 billion yuan - qhov ntsuas no yog qhov tseem ceeb hauv kev lag luam hauv tsev.
Tab sis qhov tseeb txiav txim siab lub neej ntawm cov kav dej yog lub txheej txheej peb txheej.
Muaj coob tus neeg tsuas tsom ntsoov rau sab hauv xwb, tab sis lawv tsis quav ntsej txog peb kauj ruam tseem ceeb: cov tshuaj pleev xim, cov nplaum, thiab txheej tiv thaiv xeb sab nraud. Cia peb tham txog lawv ib qho zuj zus.
Txheej 1: Epoxy Resin Primer
Qhov no yog txau ua hmoov thiab nws cov tuab yuav tsum tsis pub tsawg dua 60 micrometers. Tsis txhob saib tsis taus cov txheej nyias no. Nws yog lub luag haujlwm rau kev sib txuas nrog cov yeeb nkab hlau. Yog tias cov primer tsis tau ua kom raug, txawm tias nws tau lo rau saum toj kawg nkaus, nws yuav tsis muaj txiaj ntsig dab tsi.
Txheej thib ob: PE nplaum
Cov txheej no tuaj yeem txau lossis extruded. Qhov tuab tsawg kawg nkaus yog 140 micrometers. Muaj ib qho kev qhia txog kev siv tshuab uas tsim nyog sau tseg ntawm no: Qhov yuav tsum tau muaj zog tev tawm rau cov txheej txheem txau hmoov thiab extrusion txawv. Thaum yuav khoom, nco ntsoov nug tus neeg muag khoom seb lawv siv cov txheej txheem twg. Txwv tsis pub, yog tias koj rub nws tawm ntawm qhov chaw, nws yuav tev tawm ntawm daim tawv nqaij, uas yuav yog qhov teeb meem.
Txheej thib peb: Polyethylene txheej sab nraud
Cov txheej no yog qhov tuab tshaj plaws thiab yog tsim los ntawm kev sintering lossis los ntawm extruding los ntawm ib lub raj lossis daim ntawv. Tom qab txheej, nws yuav tsum tau txias; txwv tsis pub, nws yuav deform thaum nias thaum lub sijhawm thauj mus los. Tag nrho cov txheej tuab sib txawv nyob ntawm lub raj txoj kab uas hla. Yog tias cov yeeb nkab yuav tsum faus rau hauv av lossis raug rau cov khoom siv hnyav, qhov tsawg kawg nkaus txheej tuab yuav tsum tau nce ntxiv los ntawm 0.7 millimeters. Tus nqi tshwj xeeb feem ntau yog muab rau hauv lub rooj los ntawm tus neeg tsim khoom, thiab koj tuaj yeem xaiv raws li nws.
Rov qab mus rau lo lus nug thawj: PU lining lossis PP lining?
Yog hais yooj yim xwb, ntawm no yog cov lus qhia raws li kev paub dhau los: Cov kav dej polyurethane uas muaj cov khoom siv tiv taus kev hnav zoo dua thiab tsim nyog rau kev thauj cov khoom uas muaj cov khoom khov, xws li cov slurries thiab cov dej khib nyiab;Cov kav dej polypropylene uas muaj kabmuaj zog tiv taus kub thiab tshuaj lom neeg corrosion, thiab tsim nyog rau cov tshuaj lom neeg thiab cov xwm txheej kub siab.
Yog tias cov peev nyiaj ntawm qhov project tso cai, nws kuj tseem ua tau los sib txuas lus nrog cov chaw tsim khoom los tsim cov kev daws teeb meem ua ke. Txawm li cas los xij, qhov yuav tsum tau ua ua ntej yog tias cov khoom siv hauv paus zoo thiab peb txheej txheej tiv thaiv xeb ntawm Spiral Seam Welded Pipe yuav tsum ua tau raws li tus qauv. Qhov laj thawj vim li cas Cangzhou Spiral Steel Pipe Factory tau sawv ruaj khov hauv kev lag luam no tau ntau xyoo, qhov tseem ceeb, yog tias nws tswj hwm tag nrho cov txheej txheem nws tus kheej - dov cov khoom siv hauv paus, siv cov txheej txheem, thiab sib dhos cov txheej sab hauv - uas ntseeg tau ntau dua li kev cia siab rau cov neeg muag khoom uas sib dhos ua ke lawv cov khoom.
Tsis muaj lus teb tseeb tias "yog" thaum xaiv cov yeeb nkab, tab sis muaj cov hau kev zoo. Kuv vam tias tsab xov xwm no tuaj yeem pab koj zam qee qhov kev hloov pauv tsis tsim nyog thaum xaiv PU thiab PP.
