Ob-Wall Corrugated (DWC) cov kav dej tau dav siv rau kev tso dej, dej phwj tuaj, kev tiv thaiv kab hluav taws xob thiab kev tsim vaj tsev nyob thoob plaws ntiaj teb. Ntau qhov thib ob DWC cov kav dej ntau lawm yog nrov ntawm cov tuam txhab me thiab nruab nrab vim lawv cov nqi txuag tau zoo.
Txawm li cas los xij, thaum lub sij hawm ntev ntawm kev siv DWC yeeb nkab tsim cov cuab yeej, cov neeg ua haujlwm feem ntau ntsib ntau yam kev ua tsis tiav, cov yeeb nkab tsis xws luag thiab lub tshuab tawg. Yog tias cov teeb meem no tsis tuaj yeem daws tau raws sijhawm, koj yuav ntsib cov khoom lag luam qis, tus nqi tsis lees paub siab thiab tus nqi kho ntxiv.
Feem ntau DWC yeeb nkab tsim teeb meem, ua rau & kev daws teeb meem (Siv cov kab ntau lawm)

| 3 | Cov yeeb nkab nto muaj npuas & cua qhov | 1. Cov ntaub ntub dej los yog ntub dej rov siv dua HDPE / PP raw khoom2. Extruder venting qhov thaiv (lub tshuab qub av nkim) 3. Extrusion kub dhau heev lawm, khoom decomposed | 1. Qhuav yas raw khoom ua ntej extrusion ntau lawm2. Ntxuav extruder qhov chaw nres nkoj tsis tu ncua 3. Txo thiab ruaj khov ua haujlwm kub; tsis txhob overheating |
| 4 | DWC yeeb nkab tawg tom qab tsim | 1. Tsawg yeeb nkab txias℃ua ntej txiav2. Cov khoom siv mis tsis haum 3. Nthuav hnav txiav hniav ntawm cutter chav tsev 4. Residual stress los ntawm unmatched traction ceev | 1. Ncua qhov txias txias ntev los yog ua kom cov dej txias kom txaus2. Kho cov mis raw khoom; ntxiv modifier yog xav tau 3. Ntxig lossis hloov cov riam qub qub 4. Fine-tune traction ceev kom txo cov yeeb nkab hauv kev ntxhov siab |
| 5 | Extruder surging, cov khoom siv tsis ruaj khov | 1. Cov ntsia hlau hnyav hnyav ntawm kev siv extrusion unit2. Raw-material mixing tsis sib xws 3. Cov cua sov band kub tsis sib haum | 1. Tshawb xyuas cov ntsia hlau-thooj tshem tawm; overhaul hnav cov khoom 2. Txhim kho raw-khoom sib tov txheej txheem 3. Hloov cov cua kub uas puas lawm thiab kub thermocouples |
| 6 | Cov yeeb nkab txuas rau corrugator pwm blocks | 1. Pwm kub siab heev2. Lubricant tsis txaus ntawm corrugator3. Kev teeb tsa lub tshuab nqus tsev tsis zoo | 1. Ua kom cov dej txias txias rau corrugator pwm2. Ntxiv tsim nyog sab nraud lubrication3. Pib dua lub tshuab nqus tsev suction siab parameter |
