Muab faibcov khoom siv hlauRaws li cov txheej txheem sab hauv thiab sab nraud raws li hauv qab no:
1. Txheej txheej
Ordinary portland cement mortar yog coated sab hauv thaum zinc thiab bituminous xim yog pleev xim rau sab nraud.
2. Sab hauv txheej ntawm sulfate cement mortar
Sulfate cement, tseem hu ua high sulfate-resistant cement, muaj ib tug zoo sulfate corrosion kuj thiab ib tug dav daim ntawv thov nyob rau hauv thauj ib co corrosive nruab nrab xws li seawater.
3.Internal txheej ntawm aluminate cement mortar
Cov yeeb nkab hlau rau cov kav dej phwj tuaj ua raws li ISO7186, EN598 thiab GB / T26081 yog coated nrog aluminate cement (tseem hu ua high-alumina cement) sab hauv, nrog rau cov txiaj ntsig zoo heev rau cov tshuaj tiv thaiv corrosion thiab abrasive tsis kam uas yog ntau haum rau thauj cov dej nag, dej phwj tuaj thiab qee yam kev lag luam dej phwj tuaj.
4.Zinc-Aluminium txheej
Sab nraud ntawm cam khwb cia hlau yeeb nkab yog coated nrog zinc-Aluminium txheej (85% Zn + 15% Al) hnyav 400g / m2, uas yog haum rau cov av nrog ntau corrosivity.
5. Sab hauv txheej ntawm epoxy ceramic
Sab hauv ntawm epoxy ceramic yog ua los ntawm epoxy resin, quartz hmoov thiab lwm yam nrog ib tug qhuav zaj duab xis thickness ntawm ntau tshaj 1000μm, thiab cov zoo heev corrosion kuj hluav taws xob insulating cuab yeej ua rau nws yog ib tug nyiam txoj hauj lwm nyob rau hauv thauj cov kav dej phwj tuaj, reclaimed dej, thiab lwm yam.
6. Epoxy resin foob txheej
Cov yeeb nkab cam khwb cia nrog epoxy resin sealing txheej yog sib npaug ntawm cov cement inner-lining coated los ntawm ib txheej ntawm epoxy resin sealing, nws thickness yog txiav txim siab raws li tus yam ntxwv ntawm kis nruab nrab, thiab muaj zoo abrasive kuj thiab corrosion kuj.Ua tsaug rau lub foob txheej, nag lossis daus ntawm cov khoom phom sij tau zoo tiv thaiv, qhuas kom tsis txhob muaj kuab paug rau kis nruab nrab thiab tsim nyog rau kev xa dej ncaj qha.
7. Polyurethane txheej
Polyurethane txheej yog ua los ntawm ob-cov khoom siv polyurethane rau cov nplai, thiab nws tsis tsuas yog ua cov khoom siv sab hauv ntawm nodular cam khwb cia hlau yeeb nkab, tab sis raws li cov txheej txheem txheej txheej txheej txheej.Polyurethane txheej muaj ntau yam zoo xws li zoo abrasive tsis kam, zoo heev corrosion kuj, tsis permeation, du nto, me me kuj coefficient, ob peb volatile organic compound, zoo kawg li ib puag ncig tiv thaiv vaj tse, thiab lwm yam. Qee cov polyurethane coatings nrog ib tug thickness saum toj no 900μm yog tsuas yog siv rau thauj cov khoom nruab nrab lossis cov nruab nrab uas muaj kev huv huv siab, suav nrog cov dej mos, dej hiav txwv desalination, dej khib nyiab hauv nroog, dej khib nyiab, thiab lwm yam;thiab qee qhov nrog thickness saum toj no 700μm yog tsuas yog siv rau cov av ib puag ncig uas muaj zog corrosivity xws li cov av polluted los ntawm industrial khib nyiab dej los yog nrog tsawg tshwj xeeb kuj.
