Nyob rau hauv peb lub neej niaj hnub, cov kav dej stainless hlau feem ntau yog cov kav dej liab qab hauv lawv cov xim qub. Qee qhov muaj qhov zoo nkauj thiab muaj kev cuam tshuam, thaum lwm tus yog unpolished, nrog matte nto thiab xim tsaus. Hauv qee qhov kev kos duab kho kom zoo nkauj hauv dej, peb kuj pom peb tus kheej cov yas coated stainless hlau yeeb nkab, coated nrog xim liab lossis xiav yas rau ntawm phab ntsa stainless hlau yeeb nkab.
Cov oxidation kuj thiab corrosion kuj ntawm stainless hlau kav dej yog zoo heev. Vim li cas cov tuam ntxhab qhia txog cov yas coated stainless hlau kav? Dab tsi yog qhov cuam tshuam ntawm cov txheej txheem yas ntawm cov kav dej stainless hlau? Hnub no kuv xav muab lus teb rau sawv daws.
Nyob rau hauv lub installation ntawm stainless hlau kav, yog hais tias peb yuav tsum tau faus lawv nyob rau hauv underground qhov chaw los yog phab ntsa (tso cai rau nruab dej thiab hluav taws xob), nws yog pom zoo kom siv cov yas coated stainless hlau kav. Feem ntau, cov kav dej yas liab yog suav tias yog cov kav dej kub, thiab cov kav dej yas xiav yog cov kav dej txias. Txoj kev no, txhua tus tuaj yeem yooj yim paub qhov txawv ntawm cov kav dej kub thiab cov kav dej txias, thiab muab kev soj ntsuam kom raug, kev txiav txim siab, thiab kev tswj xyuas kev tswj xyuas qee qhov teeb meem raws sijhawm.
Niaj hnub no, nyob rau hauv kev tsim cov kav dej tswj kav dej rau kev kho kom zoo nkauj hauv tsev, peb tuaj yeem siv cov ntaub ntawv zais faus, zawj rau ntawm phab ntsa, thiab nteg cov kav dej tshwj xeeb. Hauv kev tsim stainless hlau liab xiav coated yas coated cov kav dej, cov ntsiab lus tseem ceeb suav nrog cov yeeb nkab dej txias xiav thiab cov yeeb nkab dej kub liab; Cov xim xiav thiab xim liab txheej tsim nyob rau hauv qhov project no yog hnav-resistant thiab corrosion-resistant polyethylene ntau lawm plastics rau txheej yas txheej ntawm stainless hlau liab qab kav, nrog txawv rwb thaiv tsev, corrosion kuj, thiab hnav tsis kam.
Vim hais tias nyias-walled stainless hlau kav thiab fittings yuav tsum tsis txhob tuaj mus rau hauv kev sib cuag ncaj qha nrog cov cement mortar thiab pob zeb, npog lub ntsej muag nrog cov yas txheej tuaj yeem tiv thaiv cov yeeb nkab stainless hlau los ntawm kev sib txhuam thiab khawb ntawm qhov chaw ntawm chromium oxide zaj duab xis. Hauv av los yog phab ntsa yog nyob rau hauv qhov chaw uas muaj cov av noo thiab tsis muaj zog hluav taws xob nyob rau hauv ib puag ncig, uas tuaj yeem cuam tshuam cov yeeb nkab steel hlau (tej zaum) ntev. Yas txheej tuaj yeem cais tawm tau zoo thiab txhim khu kev tiv thaiv corrosion ntawm cov yeeb nkab steel hlau.
Vim li cas stainless hlau dej yeeb nkab yuav tsum tau them nrog ib txheej ntawm polyethylene? Yog tias lwm cov ntaub ntawv tuaj yeem coated, cia peb ua ntej saib qhov zoo ntawm txheej polyethylene.
Qhov zoo ntawm cov yas coated stainless hlau kav
1. Cov yeeb nkab dej tau txais cov txheej txheem tiv thaiv polyethylene, uas muaj cov rwb thaiv tsev zoo thiab tsis muaj cua sov;
2. Cov txheej txheej polyethylene muaj cov khoom siv rwb thaiv tsev zoo heev, uas tuaj yeem tiv thaiv hluav taws xob corrosion tshwm sim los ntawm kev sib txuas ntawm cov hlau sib txawv;
Tom qab txheej txheej polyethylene ntawm cov kav dej xa dej, kev ntsuas tau zoo tuaj yeem tiv thaiv qhov tshwm sim ntawm ya raws, txias, thiab condensation. Tib lub sijhawm, nws tuaj yeem tshem tawm cov suab nrov ntawm cov kua ntws hauv cov yeeb nkab;
4. Cov txheej PE muaj qhov zoo corrosion kuj, acid thiab alkali tsis kam, thiab corrosion kuj ntawm 304 stainless hlau kav dej yog zoo.
Thaum kawg, txoj kev tshawb fawb pom tias qhov hollow tsim ntawm cov yas yas coated stainless hlau dej kav dej muaj qee qhov kev ua haujlwm rwb thaiv tsev, uas tuaj yeem txo qhov kub poob, kev siv hluav taws xob, txo cov suab nrov hauv cov kav dej, tiv thaiv cov kab mob hauv tsev, cement aging, pobzeb protrusion, lwm.
