Muab ob npaug rau- cov kav dej corrugated yog dav siv hauv cov kav dej hauv nroog, cov kav dej phwj tuaj, txoj kev culverts thiab underground cable tiv thaiv vim lawv lub nplhaib siab nruj, lub teeb yuag thiab du sab hauv bore.
Kauj Ruam 1: Kev npaj raw khoom
Lub ntsiab raw khoom rau ob - phab ntsa corrugated kav yog HDPE (High-Density Polyethylene), qee zaum PVC-U rau cov haujlwm tshwj xeeb. Cov resin yog tov nrog cov additives yuav tsum tau xws li xim masterbatch, UV stabilizer thiab kev pab raws li cov khoom formula. Cov khoom siv zoo sib xyaw ua ke ncaj qha cuam tshuam rau cov yeeb nkab lub nplhaib nruj, nto tiav thiab kev ruaj ntseg ntau lawm.
Kauj Ruam 2: Extrusion thiab Melting
Cov khoom sib xyaw yog pub rau hauv ib qho - ntsia hlau lossis ntxaib - ntsia hlau extruder. Nyob rau hauv lub extruder chim, cov khoom yog rhuab, compressed thiab yaj mus rau hauv ib tug uniform yaj. Rau ob -phab ntsa yeeb nkab ntau lawm, ob lub extruders feem ntau yog siv - ib qho rau txheej txheej corrugated thiab ib qho rau txheej sab hauv du. Lub melting kub yog ua tib zoo tswj kom ntseeg tau tias ob txheej txheej zoo kawg nkaus.
Kauj Ruam 3: Corrugation Moulding
Qhov no yog cov kauj ruam tseem ceeb ntawm DWC yeeb nkab ntau lawm. Cov khoom molten nkag mus rau hauv lub corrugator pwm uas muaj ib tug series ntawm txav pwm blocks. Lub txheej txheej yuav siv lub corrugated zoo nyob rau hauv lub tshuab nqus tsev tsim, thaum lub puab txheej tseem du. Cov pwm thaiv txav mus tas li nrog cov yeeb nkab, tsim cov yam ntxwv ob - phab ntsa qauv.
Kauj Ruam 4: Txias thiab Sizing
Tom qab corrugation, cov yeeb nkab dhau los ntawm lub tshuab nqus tsev txias. Cov dej txias tso rau ntawm cov yeeb nkab saum npoo kom khov kho cov qauv sai. Kev ua kom txias kom zoo yog qhov tseem ceeb - nrawm dhau yuav ua rau muaj kev ntxhov siab sab hauv, qeeb qeeb tuaj yeem ua rau cov corrugations.
Kauj Ruam 5: Txiav thiab stacking
Cov yeeb nkab txias yog txiav mus rau qhov ntev (feem ntau 6m lossis 12m ib thooj) los ntawm kev txiav txiav tsis siv neeg. Cov kav dej tiav lawm ces muab tso rau, tshuaj xyuas thiab ntim rau kev xa khoom. Qee cov kab ntau lawm kuj ntxiv ib lub tshuab hu xov tooj hauv online los tsim lub qhov (socket) xaus rau kev teeb tsa yooj yim.
| Txheej txheem theem | Cov cuab yeej tseem ceeb | Main Parameter | Tej Teeb Meem Saib |
|---|---|---|---|
| Cov khoom sib xyaw | Tov khoom / Hopper tshuab ziab khaub ncaws | Qhuav kub & sijhawm | Moisturize ua npuas ncauj |
| Extrusion | Ib leeg / ntxaib - ntsia hlau extruder | Melt kub 180-220℃(HDPE) | Tsis sib xws melting → tsis muaj zog phab ntsa |
| Corrugation | Corrugator nrog pwm blocks | Nqus℃& kab ceev | Kev ua tsis zoo → corrugation ntiav |
| Txias | Lub tshuab nqus tsev txias tank | Dej kub & txias ntev | Tsis sib xws shrinkage → ovality |
| Txiav | Tsis siv neeg txiav saw | Txiav ntev kam rau ua | Burrs lossis lub ntsej muag tsis sib xws |
Common Raw Materials thiab cov ntawv thov
| Khoom siv | Hom kab | Daim ntawv thov tseem ceeb |
|---|---|---|
| HDPE | 110-1200 hli | Municipal drainage, dej phwj tuaj, txoj kev culvert |
| PVC -U | 110mm-800mm | Lub tsev tso dej, cable conduit |
| PP | 90mm-600mm | Muaj dej ntws, tshuaj ua haujlwm |
Thaum xaiv ob - phab ntsa corrugated yeeb nkab extrusion kab, xyuam xim rau peb lub ntsiab lus tseem ceeb: extruder muaj peev xwm, corrugator stability thiab txias system efficiency. Cov kab ntau lawm ruaj khov txo cov nqi seem thiab txuag cov nqi khoom nyob rau lub sijhawm ntev.
