DIN30670 3pe anti-corrosion steel yeeb nkab txheej txheem ntws
1. Kev tua blasting thiab deodorizing kev kho cov kav hlau
Ua ntej txhaj tshuaj blasting thiab deodorization, cov yeeb nkab steel yuav tsum tau preheated rau 40-60 degrees nrog ib tug nruab nrab zaus induction rhaub, thiab ces dej, roj, thiab av yuav tsum tau muab tshem tawm los ntawm lub tua blasting tshuab. Qib tshem tawm xeb yuav tsum ua tau raws li GB/T8923-1988 tus qauv, Sa2. Qib 5 (ze rau qib dawb) yuav tsum muaj qhov tob ntawm 40 mus rau 100 microns ntawm cov qauv hlau thauj tog rau nkoj.
2. Epoxy hmoov txheej
Ua ntej txau, qhwv ob qhov kawg ntawm cov yeeb nkab steel nrog kraft ntawv, tom qab ntawd siv lub tshuab hluav taws xob nruab nrab induction kom sov cov yeeb nkab steel mus rau 190-230 degrees, siv electrostatic txau rau epoxy hmoov, thiab siv cov hmoov hmoov ntawm cov hlau. phaj raws li xav tau. Qhov saum npoo ntawm cov yeeb nkab steel, ua ke nrog kev ruaj khov ntawm cov khoom siv hauv paus ntawm qhov kub thiab txias, muaj cov khoom zoo tshaj plaws los tiv thaiv corrosion thiab zoo tshuaj corrosion kuj. Cov txheej txheej ntom ntom yog du, hnav-resistant thiab kub-resistant.
3. Extrude kua nplaum
Raws li cov thickness yuav tsum tau ntawm cov nplaum txheej thiab polyethylene, lub ntsiab lub cev muaj zog thiab ntsia hlau ceev ntawm lub extruder yog kho kom tau raws li qhov yuav tsum tau ntawm lub extrusion ntim. Thaum cov epoxy hmoov nyob rau hauv daim ntawv gel, peb siv lateral winding tshuab los coated cov nplaum thiab PE ntawm cov yeeb nkab steel. Cov nplaum epoxy hmoov thiab polyethylene yog polymerized los tsim peb txheej txheej. Tom qab tsim, peb kab ntawm rollers yog siv los ua , ua rau hauv peb txheej txheej uas yog fused thiab compacted ua rau saum npoo ntawm tag nrho cov txheej txheem du thiab tsis muaj npuas thiab tsis xws luag.
Cov nplaum nplaum ua haujlwm ruaj khov, cov nplaum nplaum muaj zog, thiab cov yeeb yaj kiab yog sib npaug.
Lub extrusion kub ntawm PE yog 230-260 degrees. PE muaj zog tiv thaiv kev laus corrosion thiab ua haujlwm zoo rau ib puag ncig kev ntxhov siab tawg thiab elongation.
4. Txias ntawm cov raj coated
Raws li cov khoom siv kev ua tau zoo ntawm peb txheej txheej, nws yuav tsum tau ua kom txias qeeb, thiab qhov kub ntawm lub raj cua txias yuav tsum tsis pub tshaj 60 degrees.
5. Jiping
Thaum lub sij hawm tsim cov txheej txheem, lub tshuab hluav taws xob hluav taws xob hauv online yog siv rau kev pleev xim, thiab 100% ntawm qhov hluav taws xob pom hluav taws xob yog 25 KV. Tsis muaj funnel yuav tsum tau 25V to detection.
6. Txheej cov khoom ua tiav
Siv lub groove grinder rau tshuab thiab kos cov yeeb nkab kawg.
