Nyob rau hauv xyoo tas los no, nrog kev tshwm sim tsis tu ncua ntawm cov kav dej tshiab, cov kav dej yas-coated tau siv rau kev xa roj. Cov kav dej yas-coated yog cov roj xa hluav taws xob tshwj xeeb uas muaj peev xwm xa cov roj ntau yam xws li cov pa roj ntsha thiab biogas, ua rau lawv muaj ntau yam haujlwm.
Yas-coated steel kav muaj ntau yam kev siv. Tag nrho cov kav hlau steel nrog lawv cov txheej txheem sab hauv thiab sab nrauv kho nrog cov tshuaj poob rau hauv qeb ntawm cov kav dej yas-coated steel. Feem ntau siv cov tshuaj yas-txheej txheej rau txheej txheej ntawm cov kav hlau muaj xws li polyethylene, epoxy resin, thiab lwm yam txheej. Lub neej kev pabcuam ntawm cov kav dej yas-coated steel yog ntev dua li ntawm cov yeeb nkab yav dhau los, feem ntau kav ntev txog 50 xyoo. Txawm li cas los xij, tom qab txheej txheej yas, cov khoom ntawm cov yeeb nkab qub lub cev hloov pauv, yog li ceev faj yuav tsum tau siv thaum lub sijhawm teeb tsa.
Cov yam ntxwv ntawm cov kav dej yas-coated steel: Lawv muaj kev tiv thaiv corrosion thiab tiv thaiv xeb. Sab hauv phab ntsa ntawm epoxy resin-coated kauv steel yeeb nkab yog tus du heev, nrog kev sib txhuam tsawg, ua rau nws tsim nyog rau cov kav dej los yog cov kav dej haus. Tsis tas li ntawd, cov phab ntsa sab nrauv ntawm lub raj xa dej tuaj yeem pleev xim nrog cov xim zoo nkauj, txhim kho nws txoj kev zoo nkauj.
Piv nrog rau cov khoom siv kav dej ib txwm muaj uas ua rau brittleness thiab xeb, yas-coated steel kav muaj kev pab cuam lub neej tshaj 50 xyoo nrog tus nqi qis tag nrho. Lawv raug nqi ntau dua li cov kav dej tooj liab thiab galvanized. Yog li ntawd, lawv tsis tsuas yog siv rau cov kav dej hauv tsev, tab sis kuj yog cov kav dej hauv nroog hauv nroog. Piv txwv li, cov kav dej yas-coated steel yog siv los ua cov roj av thiab cov kav dej, ua kom cov kav dej ntawm cov kav dej ib txwm muaj zog thaum ua kom sib dua, muaj kev tiv thaiv tsawg dua, thiab tso cai rau cov kua dej nrawm dua hauv cov kav dej.
Khoom Nta: Mining yas-coated kav (tom qab no hu ua zaj duab xis-coated yas steel kav) yog steel-yas composite kav nrog anti-static thiab nplaim-retardant zog. Lawv raug tsim los ntawm kev siv cov khoom siv tshwj xeeb polyethylene rau sab hauv thiab sab nrauv ntawm cov kav hlau zoo tib yam los ntawm cov txheej txheem tshwj xeeb.
(1) Cov khoom siv no siv cov txheej txheem polyethylene, nrog rau nws cov khoom tiv thaiv zoo li qub thiab nplaim hluav taws sib npaug sib npaug ntawm qhov chaw thiab txheej txheej hauv cov yeeb nkab, ua tau raws li qhov yuav tsum tau ua ntawm mt181 thiab tsim nyog siv rau hauv qhov chaw tawg thiab tawg hauv mines.
(2) Muaj zog adhesion: Tom qab txheej, sib txuas, thiab kho, sab hauv thiab sab nrauv ntawm cov yeeb nkab yas-coated steel muaj qhov adhesion quab yuam ntau dua lossis sib npaug li 30N / 10mm, uas tsis muaj kev puas tsuaj tom qab kev cuam tshuam thiab kev ntsuam xyuas tearing nrog rauj poob .
(3) Corrosion resistance, low fouling tendency, and low fluid resistance: Cov kav dej muaj zog tiv taus acids thiab alkalis, ua rau lawv haum rau kuv cov dej uas muaj leej faj thiab cov dej uas muaj calcium thiab magnesium ions. Vim lawv qhov siab du du, tsis muaj dej tsis kam, thiab tiv thaiv fouling, lawv tuaj yeem txo cov pa phem thib ob.
(4) Lub peev xwm muaj peev xwm siab: Polyethylene hmoov muab cov txheej txheem yas zoo heev, ua ke nrog lub zog txhua yam ntawm cov kav hlau, uas ua rau muaj zog tiv thaiv sab nraud xws li kev poob siab thiab khoov.
Kev Siv Tseem Ceeb thiab Scope ntawm Daim Ntawv Thov: Cov kav dej yas-coated steel yog cov kav dej uas muaj ntau yam siv hauv av hauv cov mines rau cov dej thiab cov dej ntws, qhov cua zoo, qhov cua tsis zoo, qhov hluav taws xob tsis zoo, coal slurry spraying, gas drainage, thiab lwm yam. nominal siab.
