Kev tswj xyuas zoo rau 3PE cov kav dej sib xyaw yog cov txheej txheem dav dav uas muaj ntau theem thiab ntau yam. Hauv qab no yog cov kauj ruam ntxaws ntxaws rau kev tswj xyuas zoo ntawm 3PE cov kav dej sib xyaw, npog cov khoom siv raw, cov txheej txheem tsim khoom, kev tshuaj xyuas cov khoom tiav, thiab kev tuav tom qab:
1. Kev Tswj Xyuas Cov Khoom Siv Zoo
1.1 Kev Tswj Xyuas Zoo ntawm Epoxy Hmoov, Adhesive, thiab Polyethylene:
Xyuas kom meej tias cov ntaub ntawv raw yog los ntawm cov neeg muab kev ntseeg siab thiab ua raws li cov qauv thiab cov kev qhia tshwj xeeb.
Ua kev soj ntsuam zoo ntawm cov khoom siv raw, suav nrog kev kuaj xyuas lub cev, tshuaj lom neeg muaj pes tsawg leeg, lub zog nplaum, thiab lwm yam kev ntsuas tseem ceeb.
Saib xyuas qhov chaw khaws cia ntawm cov khoom siv raw kom tsis txhob ya raws, kev sib kis, lossis kev puas tsuaj.
1.2 Kev Tswj Xyuas Zoo ntawm Cov Yeeb Nkab Hlau:
nruj me ntsis tshuaj xyuas cov kav hlau xa tuaj, suav nrog kev txheeb xyuas cov kab yeeb nkab kab, phab ntsa tuab, cov yeeb nkab naj npawb, cov chaw tsim khoom daim ntawv pov thawj, thiab lwm yam ntaub ntawv.
Tshawb xyuas cov yeeb nkab steel nto rau qhov tsis xws luag xws li khawb, dents, thiab lwm yam, thiab xyuas kom meej tias cov welds muaj kev hloov pauv nrog qhov siab tshaj qhov siab tsis pub tshaj qhov ntsuas.
Ua qhov tsim nyog tu thiab derusting kev kho mob ntawm cov kav hlau los txhim kho cov adhesion ntawm cov txheej txheem anticorrosive.
2. Kev Tswj Xyuas Kev Ua Haujlwm Zoo
2.1 Steel Yeeb Nkab Kev Kho Mob:
Siv cov khoom siv preheating rau preheat cov kav hlau los txhim kho kev ua haujlwm zoo.
Siv cov cuab yeej tua blasting kom huv si huv cov yeeb nkab steel nto, kom ntseeg tau tias qhov yuav tsum tau ua kom huv si.
Ua kev ntsuam xyuas roughness ntawm derusted steel yeeb nkab nto kom paub meej tias cov qauv thauj tog rau nkoj qhov tob yog nyob rau hauv qhov kev teev tseg.
2.2 Daim ntawv thov ntawm Anticorrosive Coatings:
nruj me ntsis tswj qhov kub thiab txias, ceev, thiab thickness ntawm cov epoxy hmoov los xyuas kom meej ib tug uniform txheej tsis muaj npuas los yog tawg.
Daim ntawv thov ntawm cov nplaum yuav tsum zoo ib yam thiab tsis muaj qhov tsis nco qab los txhim kho tag nrho cov kev ua tau zoo ntawm cov txheej txheem anticorrosive.
Lub qhwv ntawm polyethylene yuav tsum nruj thiab tsis muaj wrinkles, kom ntseeg tau tias kev ncaj ncees thiab sealability ntawm anticorrosive txheej.
2.3 Tswj kev tsim cov txheej txheem:
nruj me ntsis tswj cov txheej txheem tsis xws li tsav kab ceev, steel yeeb nkab cua sov kub, thiab cua kub kub ntawm nplaum thiab polyethylene.
Ua kev soj ntsuam pom ntawm cov txheej txheem tiv thaiv kom tsis txhob muaj qhov pits, npuas, wrinkles, lossis lwm yam tsis xws luag.
3. Kev tshuaj xyuas cov khoom tiav
3.1 Kev soj ntsuam ntawm txheej txheej:
Siv lub tshuab hluav taws xob hluav taws xob los ntsuas cov txheej txheem tiv thaiv kom tsis txhob muaj cov pa tawm, kom tsis txhob muaj cov ntsiab lus to.
Ntsuam xyuas lub zog ntawm kev sib raug zoo, kev cuam tshuam tsis kam, tshuaj lom neeg ua haujlwm, thiab lwm yam khoom ntawm txheej anticorrosive.
3.2 Kev tshuaj xyuas qhov muag:
Ua kev soj ntsuam pom ntawm cov kav dej tiav 3PE, suav nrog cov xim txheej, gloss, uniformity, thiab lwm yam.
Xyuas seb cov yeeb nkab kawg kho yog du thiab yog tias cov txheej txheem bevel ua tau raws li qhov yuav tsum tau ua.
3.3 Kev soj ntsuam ntawm qhov ntev thiab qhov tshwj xeeb:
Ntsuas qhov ntev thiab qhov tshwj xeeb ntawm cov kav dej tiav kom ua tau raws li cov qauv tsim thiab cov qauv tsim.
4. Tom qab tuav
4.1 Pipe End Treatment:
Ua cov kev kho tshwj xeeb ntawm cov yeeb nkab kawg, xws li tswj qhov ntev ntawm qhov tshwj xeeb kawg thiab chamfering lub ntsej muag kawg ntawm txheej polyethylene.
4.2 Ntim thiab Cia:
Ua kom zoo pob tiav 3PE cov kav dej sib xyaw kom tsis txhob muaj kev puas tsuaj thaum thauj thiab khaws cia.
Qhov chaw cia khoom yuav tsum qhuav, zoo-ventilated, thiab tsis muaj corrosive gases los tiv thaiv kev laus los yog kev puas tsuaj rau txheej anticorrosive.
5. Cov ntaub ntawv zoo thiab traceability
Tsim kom muaj cov ntaub ntawv zoo tshaj plaws los sau cov ntaub ntawv tshawb xyuas raw khoom, kev tswj cov txheej txheem ntau lawm, kev tshuaj xyuas cov khoom tiav, thiab lwm theem.
Ua kom zoo traceability kom ntseeg tau tias qhov ua rau muaj teeb meem zoo tuaj yeem txheeb xyuas sai thiab ntsuas kev txhim kho thaum lawv tshwm sim.
