Cov yam ntxwv ntawm kev ua tau zoo
Kev Tiv Thaiv Zoo heev
Nrog rau cov qauv molecular ntom ntom thiab cov coefficient permeability qis, LLDPE geomembrane tuaj yeem tiv thaiv cov kua dej xau. Nws cov nyhuv seepage - pov thawj zoo ib yam li HDPE geomembrane, ua rau nws siv tau rau cov haujlwm uas xav tau kev tswj seepage.
Kev Yooj Yim Zoo
Nws ua rau pom kev ywj pheej zoo heev thiab tsis yooj yim tawg thaum kub qis, nrog rau qhov kub thiab txias tiv taus ntawm kwv yees li - 70 ° C txog 80 ° C. Qhov no tso cai rau nws hloov kho rau cov av tsis sib xws lossis cov chaw muaj kev ntxhov siab dynamic, xws li cov haujlwm txuag dej hauv cov roob nrog cov av nyuaj.
Muaj zog tiv taus kev raug mob
Cov membrane muaj zog heev, thiab nws txoj kev tiv taus kua muag thiab kev cuam tshuam zoo dua li cov HDPE du membranes. Thaum lub sijhawm tsim kho, nws tuaj yeem tiv taus qhov tawg los ntawm pob zeb lossis cov khoom ntse, txo qhov kev puas tsuaj tsis tau xav txog thiab txhim kho kev ntseeg siab ntawm qhov project.
Kev Hloov Kho Zoo ntawm Kev Tsim Kho
Nws tuaj yeem txuas nrog los ntawm kev vuam kub - yaj, thiab lub zog sib koom ua ke siab, ua kom ntseeg tau tias muaj kev tiv thaiv kev seepage. Tib lub sijhawm, nws cov ductility zoo ua rau nws yooj yim khoov thiab ncab thaum lub sijhawm tsim kho, thiab nws tuaj yeem haum rau cov hauv paus nyuaj xws li cov av tsis sib xws thiab cov qhov av hauv paus, txo qhov nyuaj ntawm kev tsim kho.
Kev Tiv Thaiv Kev Tshuaj Zoo Corrosion
Nws muaj qee yam peev xwm tiv taus qhov xeb ntawm cov kua qaub, alkali, thiab ntsev, thiab tsim nyog rau feem ntau cov xwm txheej tsis muaj dej ntws. Nws tuaj yeem tiv taus qhov xeb ntawm ntau yam tshuaj lom neeg mus rau qee qhov thiab ua kom lub neej ua haujlwm ntev.
Cov Ntawv Thov
Cov Haujlwm Txuag Dej
Nws yog qhov tsim nyog rau cov haujlwm tiv thaiv dej ntws ntawm cov pas dej me thiab nruab nrab, cov kwj dej, thiab cov thoob dej cia khoom, tshwj xeeb tshaj yog nyob rau hauv thaj chaw uas muaj av nyuaj lossis tsis sib xws, xws li kev tsim cov pas dej kuaj ntawm Loess Plateau, qhov twg nws qhov kev ywj pheej zoo thiab kev ua tau zoo tiv thaiv dej ntws tuaj yeem coj los ua si. Rau cov haujlwm txuag dej ib ntus lossis ib ntus, xws li cov thoob dej cia khoom thaum muaj xwm txheej ceev, nws cov txiaj ntsig ntawm kev tsim kho yooj yim thiab tus nqi qis ua rau nws yog qhov kev xaiv zoo tshaj plaws.
Cov Haujlwm Tiv Thaiv Ib Puag Ncig
Nws siv tau ua ib txheej tiv thaiv dej ntws ib ntus rau cov chaw pov tseg me me, tiv thaiv dej ntws rau kev tswj cov pas dej, thiab cov ntaub thaiv rau cov pas dej khib nyiab hauv kev lag luam (hauv cov xwm txheej tsis muaj zog heev), pab tiv thaiv kev xau ntawm cov pa phem thiab tiv thaiv ib puag ncig.
Kev Ua Liaj Ua Teb thiab Kev Cog Qoob Loo
Nws yog siv dav hauv kev tiv thaiv kev ntws ntawm cov pas dej ntses thiab cov pas dej cw, uas tuaj yeem tiv thaiv kev xau dej thiab txhim kho kev siv cov peev txheej dej. Nws kuj tseem siv tau rau kev tiv thaiv kev ntws ntawm cov thoob dej ua liaj ua teb, cov biogas digesters, thiab cov dej noo - pov thawj thiab cov hauv paus - cais tawm ntawm qab ntawm cov tsev cog khoom, thiab tuaj yeem hloov kho rau qhov me me ntawm cov av vim nws qhov yooj ywm.
Kev Thauj Mus Los thiab Kev Tsim Kho Hauv Lub Nroog
Nws siv tau ua ib txheej tiv thaiv dej noo rau txoj kev, hloov cov txheej xuab zeb ib txwm muaj thiab txo cov nqi ntawm txoj haujlwm. Nws kuj tseem siv tau rau kev cais cov kav dej hauv av thiab cov qhov av cable kom tiv thaiv cov chaw hauv av kom tsis txhob muaj dej ntws.
