Cov txheej txheem ntau lawm ntawm 316 stainless hlau yas coated coil raj

• Raj tsim: Cov txheej txheem pib los ntawm kev txias dov lub stainless hlau kauj rau hauv cov hlau tiaj tus kheej. Lub stip strip yog tom qab ntawd maj mam khoov rau hauv ib lub tshuab cylindrical los ntawm cov tshuab yob.
• Vuam (ERW): Cov npoo ntawm lub tiaj tus kab txaij yog welded ua ke siv siab {{zaus hluav taws xob tiv thaiv (ERW). Lub raj yog welded txuas ntxiv mus ua tus qauv seamless. Seamless tubes feem ntau yog extruded rau hauv lub plab khoob, tab sis Welded Tubes tseem yog ib qho kev xaiv sib xws rau cov kauj vab.

• Ci annaling: tom qab vuam, lub raj yog ci ci ci ci. Lub raj yog rhuab rau 1050-1150℃nyob rau hauv ib qho inert lossis txo cov cua (hydrogen lossis ammonia). Cov kauj ruam no pab rov qab cov corrosion tsis kam ntawm cov hlau stainless thiab tshem tawm kev ntxhov siab tshwm sim los ntawm vuam.
• Pickling: Tom qab annaling, cov yeeb nkab steel yog pickles nyob rau hauv nitric acid / hydrofluoric acid tov rau tshem tawm cov nplai oxide lossis cov xim tawv nqaij los ntawm vuam.
• Hla: Cov yeeb nkab steel yog passivated los ntawm kev ntxuav nws nrog nitric acid kom rov qab cov roj chromium oxide uas muab rau kev ua kom corrosion.

• Kev Tu: Cov yeeb nkab steel yog kom huv thiab degreased tshem cov roj, cov paug, thiab roj uas tuaj yeem cuam tshuam cov nplaum ntawm PVC txheej. Alkaline cov tshuaj huv los yog dej {-} ath red tequers feem ntau yog siv.
• Kev Kho Mob Deg Dotrement: Cov yeeb nkab steel yog tua pe los yog cov xuab zeb blasted rau me ntsis roughen rau saum npoo av thiab txheej yas.

• Extrusion Txheej: Kev ntxuav thiab npaj cov yeeb nkab steel hlau yog tom qab rub los ntawm Crosshead Tuag Txuas nrog tus extruder. Lub pvc compound yog yaj thiab yuam dhau ntawm txoj kev tuag, thiab cov txheej txheej tau thov rau cov yeeb nkab steel raws li nws txav.
• Extruder: Extruder yaj lub pvc ntawm qhov kub ntawm 180-200 Qib (nyob ntawm PVC hom) thiab siv txheej txheem sib txuas ntxiv thiab cov yeeb nkab nyob ib ncig ntawm cov yeeb nkab steel.
• Txias thiab sizing: tom qab coating nrog PVC, tus kab hlau hla los ntawm ntu txias uas nws tau raug rau dej txau lossis lub tsheb txias. Tus txheej txheem no accordies rau PVC txheej.
• Sizing: tom qab txias, pvc - txheej txheej ci los ntawm cov tshuab sizing lossis tswj tau qhov xav tau ntawm cov yeeb nkab hlau.
• Coiling: Tus tiav lawm pvc - Coated yeeb yog ces kev txhab mus rau reel lossis lig rau yooj yim tuav thiab tsheb thauj mus los. Nws kuj tseem tuaj yeem txiav rau lub sijhawm ntev uas yuav tsum tau ua.

Qhov kev sib txuas ntawm PVC rau stainless hlau yog tsuas yog nqa los ntawm cov neeg kho tshuab khoom (vim yog cov khoom siv ntxhib) thiab siv tshuaj lom neeg (yog tias ib tug primer (yog tus primer (yog tias ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog tias ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer (yog ib tug primer). Thaum lub sij hawm cov txheej txheem Extrusion, cov yeeb nkab yog me ntsis rhuab kom cia Molten PVC rau fuse tight kom nruj rau cov hlau nto. Tej zaum qhov thermal sib txuas no kuj tseem tshwm sim.

Xyuas kom meej uniform los ntawm coating thickement tshuaj ntsuam; Kev kuaj xyuas qhov muag thiab sab hauv kev pom zoo rau qhov tsis xws xeeb thiab ntsuas qhov ntev; Adhesion lub zog kev xeem ntawm pvc txheej; kev cuam tshuam thiab kev xeem dabtsi; Ntsev tshuaj ntsuas, thiab lwm yam, los ntsuas cov yeeb nkab.

 

 

PVC {-} coated 316 stainless hlau kav ua tau raws li cov qauv kev tswj hwm zoo kawg nkaus, nrog rau qhov ntev, suav nrog qhov ntev, suav nrog qhov ntev, thiab cov khoom siv mechanies.
