AWWA C213 Kauv Hlau Yeeb Nkab yog ib hom kev tiv thaiv corrosion rau FBE. Qee cov kav hlau ua AWWA C213 FBE anticorrosion rau ntawm phab ntsa sab hauv, thiab qee cov kav hlau ua AWWA C213 FBE anticorrosion rau sab hauv thiab sab nraud.
AWWA C 213 Kauv Hlau Yeeb Nkab Txheej Txheej Txheem Tswj
Flow daim ntawv ntawm FBE thiab polyurethane txheej txheej txheem
Kev piav qhia ntawm FBE thiab polyurethane txheej txheej FBE
1 Deg Kev Npaj Cov Yeeb Nkab Hlau
2 Ntxuav cov yeeb nkab nto
Roj thiab cov kab mob ntawm cov yeeb nkab sab nraud yuav tsum tau muab ntxuav tawm thiab cov roj tuaj yeem ntxuav nrog hnyav.
3 Preheating
Cov kav dej yuav tsum tau rhuab mus rau qhov kub ntawm qhov kub tsawg dua lossis sib npaug li 60 ° C thiab ua kom siab tshaj qhov dej lwg taw tes ntawm 3 ° C kom tshem tawm cov dej noo ntawm cov yeeb nkab phab ntsa thiab ua kom lawv npaj rau saum npoo.
4 Parameters rau txhaj tshuaj blasting
a) Cov cuab yeej tua blasting yog ib txheej kaw ntawm kev ua haujlwm kaw. Nws tuaj yeem lav qhov kev ua haujlwm blasting ib txwm los ntawm kev tswj xyuas tus naj npawb ntawm kev hloov pauv ntawm cov kab sib kis thiab qhov tam sim no ntawm lub cev muaj zog ntawm lub tshuab txhaj tshuaj blasting.
b) Tus naj npawb ntawm cov kiv puag ncig ntawm cov kab sib txuas yuav tsum tau txiav txim siab los ntawm qhov ntom ntawm cov hlau txhaj tshuaj los tsoo cov yeeb nkab steel raws li qhov yuav tsum tau ua rau chav blasting. Qhov loj dua qhov ntom ntawm cov hlau txhaj tshuaj, cov nyhuv blasting yuav zoo dua. Kev ua kom huv huv ntawm blasting yuav tsum tswj hwm ntawm Sa 2.5 thiab cov kav hlau yuav tsum tau kuaj xyuas thiab sau ib qho los ntawm ib qho. Qhov tob ntawm txoj kab thauj tog rau nkoj ntawm FBE coated kav yuav tsum tswj nyob rau hauv thaj tsam ntawm 50 ~ 100μm. Qhov kis ceev ceev yuav tsum tau sau ib zaug hauv cov ntaub ntawv hloov pauv ntawm txhua txoj haujlwm.
Cov yeeb nkab cua sov
Kev tswj qhov kub thiab txias: Qhov kub rau kev siv cov yeeb nkab steel yuav tsum tau tswj raws li qhov yuav tsum tau ua ntawm curing nkhaus ntawm hmoov. Daim ntawv thov kub tuaj yeem pom tau los ntawm kev kho lub zog nruab nrab-ntau zaus. Qhov ntsuas kub tuaj yeem ntsuas nrog cov ntsuas kub hauv online lossis kuaj nrog ntsuas kub chalk lossis tes tuav thermal detector. Qhov kub ntawm cov yeeb nkab saum npoo yuav tsum tsis txhob siab tshaj 246 degree.
1 Hmoov txau
Daim ntawv thov ntawm cov hmoov yog los coated epoxy hmoov nyob rau saum npoo ntawm cov yeeb nkab steel uniformly nrog static daim ntawv thov txoj kev. Lub thickness ntawm hmoov yuav tsum tsis pub tsawg tshaj 500µm.
2 Kev soj ntsuam zaum kawg
3 Qhov tshwm sim ntawm cov kav dej coated Cov xim yuav tsum sib xws, tsis muaj qhov tsis xws luag thiab tsis sib xws, tsis muaj qhov tsis zoo thiab laminations.
4 Kev txheeb xyuas qhov dej xau
Lub tshuab hluav taws xob hluav taws xob hluav taws xob yog siv los txheeb xyuas qhov to tom qab tsim khoom. Qhov ntsuas hluav taws xob ntawm qhov taw tes tawm yog 2KV. Kev kuaj pom cov dej xau yuav tsum raug txheeb xyuas thiab kho. Kev kuaj pom ntawm qhov to ntawm txhua cov yeeb nkab steel yuav tsum raug sau tseg tseeb.
