HDPECov kav dej yas tau siv dav hauv kev lag luam mining vim lawv cov yam ntxwv tshwj xeeb. Cov kav dej no hloov tau yooj yim, hnav-tiv taus, ruaj khov, thiab tuaj yeem ua rau cov pob qij txha tsis muaj paug. Lawv tuaj yeem siv rau hauv ntau yam huab cua thiab struts, yog li yoog mus rau qhov sib txawv ntawm qhov chaw ib puag ncig. Lawv kuj tseem tuaj yeem txuas nrog ua ke siv cov khoom siv hluav taws xob sib xyaw ua ke, uas tso cai rau lawv siv tau ntev.
PE kav feem ntau siv nyob rau hauv kev lag luam mining kom muaj kev nyab xeeb kev thauj mus los los ntawm cov tshuaj tiv thaiv zoo heev.
Kev cia siab ntawm cov kav dej yas hauv kev lag luam mining
Kev siv high-density polyethylene (HDPE) pipelines hauv kev lag luam mining tam sim no muaj ntau dua li yav dhau los. Tam sim no, ntau daim ntawv thov tsis siv hlau, tab sis HDPE kav dej muaj txiaj ntsig zoo, kev yooj yim ntawm kev teeb tsa thiab tuav tau yooj yim, tsis tshua muaj kev saib xyuas, thiab lub zog zoo thiab kev ua haujlwm ntawm lub cev.
Qhov teeb meem ntawm corrosive mining thiab tus nqi kom zoo dua ntawm kev siv HDPE thiab PE pipelines tau yuam kom cov mining kev lag luam nce hloov ntawm cov kav hlau mus rau cov kav dej yas. Yog li ntawd, cov kav dej no muaj kev xav tau siab hauv kev ua lag luam tsis ntev los no.
Yog vim li cas siv cov kav dej HDPE hauv kev lag luam mining
Qhov kev txhawb siab loj tshaj plaws rau kev siv cov kav dej HDPE hauv kev lag luam mining yog tus nqi. Cov kav xa hluav taws xob qis qis pab txo nqi tag nrho cov mining. Cov txiaj ntsig-cov txiaj ntsig no tau nthuav dav los ntawm qhov muaj peev xwm siv HDPE hauv 24/7 kev teeb tsa, kev saib xyuas yooj yim, thiab tsis muaj kev pheej hmoo ntawm kev sib dhos tsis raug. Tsis tas li ntawd, lub zog ntawm HDPE yog txaus los tiv thaiv kev puas tsuaj los ntawm kev hloov siab thaum lub sijhawm ua haujlwm thiab kev thauj mus los ntawm cov kua dej thaum lub sijhawm mining.
Lwm qhov laj thawj tseem ceeb vim li cas cov kav dej HDPE tau siv hauv kev lag luam mining yog lawv qhov yooj yim ntawm fusion. Rau cov kav dej no, txoj kev sib txuas niaj hnub no yog ob qho yooj yim thiab nyab xeeb rau kev siv. Tsis tas li ntawd, qhov sib koom ua ke yog ruaj khov, tiv thaiv kev sib tw, thiab yooj yim los tswj. Cov pob qij txha no tseem tuaj yeem tiv taus qhov kub thiab txias hloov hauv huab cua huab cua.
Yog li ntawd, kev nce qib ntawm txoj kev sib txuas tau ua rau muaj kev nce hauv kev siv cov kav dej HDPE hauv kev lag luam mining. Hauv qhov sib piv, cov txheej txheem ib txwm muaj ob qho tib si siv zog thiab nyuaj.
Kev siv cov kav dej HDPE hauv kev tsuas tuaj yeem txo qhov kev pheej hmoo ntawm kev raug mob thaum lub sijhawm tu, kev teeb tsa, kev thauj mus los, thiab kev rhuav tshem. Piv txwv li, kev sib txuas yooj yim tuaj yeem tiv thaiv kev puas tsuaj thaum tsiv thiab ua haujlwm fused cov khoom siv kom tso pa tawm thiab haus luam yeeb.
Qhov zoo ntawm HDPE thiab PE pipelines hauv kev lag luam mining
Kev nyab xeeb thiab kev ntseeg siab yog qhov tseem ceeb tshaj plaws thaum xaiv cov kav dej rau kev lag luam mining. Tsis tas li ntawd, cov kav dej yuav tsum yog xeb pov thawj, tawg resistant, thiab corrosion-resistant. Tsis tas li ntawd, ntau lub tuam txhab tam sim no tab tom tshawb nrhiav kev siv cov kav dej ib puag ncig hauv kev lag luam mining.
Kev lag luam mining suav nrog kev siv tshuaj, suav nrog ntau dua cov tshuaj reactive thiab corrosive. Hom tshuaj lom neeg tshwj xeeb nyob ntawm cov khoom yuav tsum tau mined. Lawv suav nrog nitric acid, sulfuric acid, ammonium nitrate, thiab cov hlau hnyav xws li mercury thiab lead. Yog li ntawd, kev tiv thaiv corrosion ntawm PE kav thiab HDPE kav yog qhov tseem ceeb thaum siv rau txhua lub hom phiaj ntawm qhov chaw. Lub raj xa dej yuav tsum tiv thaiv kev puas tsuaj rau cov tshuaj no, yog li tiv thaiv kom tsis txhob muaj cov kua dej thaum lub sijhawm thauj mus los thiab txawm tias tiv thaiv kev kis kab mob ntawm cov khoom rho tawm.
PE pipelines tuaj yeem siv rau hauv kev lag luam mining uas siv cov pH acid qis thiab siab pH caustic daws. Lawv tuaj yeem siv rau hauv qhov hnyav tshuaj mining ib puag ncig yam tsis muaj nqi ntxiv vim kev puas tsuaj.
Lawv lub zog muaj zog kuj muaj qhov zoo hauv kev tsuas yog vim nws pab tiv thaiv kev puas tsuaj thaum tuav cov khib nyiab thiab cov kua dej hauv lub zog.
Kev siv cov kav dej hlau tsis yog tsuas yog kim, tab sis kuj tuaj yeem ua rau muaj tshuaj lom neeg puas tsuaj. Ntawm qhov tsis sib xws, PE kav dej muaj cov nqi qis. Koj yuav tsis ntxiv cov nqi tsis tsim nyog rau cov txheej txheem mining. Tsis tas li ntawd, tus nqi ua haujlwm thaum lub sijhawm teeb tsa yog qhov tsawg.
