Taw qhia:
Thaum xaiv cov khoom siv sab hauv kom haum rau cov kav dej phwj, cov neeg txiav txim siab feem ntau ntsib ntau txoj kev xaiv. Cov ntaub ntawv siv feem ntau yog polypropylene, polyurethane thiab epoxy. Txhua yam ntawm cov ntaub ntawv no coj tus cwj pwm tshwj xeeb rau lub rooj. Hauv tsab xov xwm no, peb yuav saib tob txog cov yam ntxwv thiab cov txiaj ntsig ntawmcov kav dej polypropylene uas muaj cov xov hlau, cov kav dej polyurethane uas muaj cov ntaub thaiv, thiab cov ntaub thaiv dej phwj epoxy los pab koj xaiv tau zoo.
Polypropylene liner:
Cov yeeb nkab uas muaj polypropylene yog ib qho kev xaiv nrov rau cov kev siv dej phwj vim nws tiv taus tshuaj lom neeg zoo heev. Polypropylene yog ib hom thermoplastic polymer uas tiv taus tshuaj lom neeg zoo heev rau cov khoom siv hauv pem teb. Hom kev hauv pem teb no zoo tagnrho rau kev teeb tsa cov kua dej corrosive lossis qhov twg xav tau kev tiv taus hnav siab. Cov yeeb nkab uas muaj polypropylene yog lub teeb yuag, ua rau nws yooj yim dua rau kev thauj mus los thiab teeb tsa. Tsis tas li ntawd, lawv muaj kev sib txhuam tsawg rau kev ntws dej zoo thiab txo kev siv hluav taws xob.
Cov yeeb nkab polyurethane:
Cov yeeb nkab polyurethanenws tiv taus kev txhuam, kev cuam tshuam thiab kev txhuam tsis zoo. Qhov no ua rau nws yog qhov kev xaiv zoo heev rau cov kav dej phwj uas raug cov tshuaj txhuam lossis cov nqi ntws siab. Lub polyurethane liner muab ib txheej du thiab ruaj khov ntawm kev tiv thaiv uas txo qhov muaj feem ntawm cov av noo uas tuaj yeem ua rau cov kav dej txhaws. Tsis tas li ntawd, polyurethane paub txog nws qhov kev ywj pheej, muaj peev xwm tiv taus kev txav mus los hauv av thiab kev hloov pauv kub yam tsis muaj kev tawg lossis tawg.
Epoxy txheej ntawm cov kav dej phwj tuaj:
Epoxy txheej ntawm cov kav dej phwj tuajyog nrov rau lawv lub peev xwm kho cov khoom siv qub yam tsis tas yuav khawb av kim. Epoxy liner tsim ib qho khoom siv tawv, tiv taus xeb kom tiv thaiv kev xau, kev nkag mus rau hauv paus thiab kev puas tsuaj. Txoj kev no ua kom muaj kev tiav sab hauv du thiab ua kom muaj peev xwm ntws ntawm lub cev dej phwj tuaj thaum lub sijhawm ntev nws lub neej kev pabcuam. Tsis tas li ntawd, epoxy sewer liners yog cov nqi tsim nyog, txuag sijhawm thiab zoo rau ib puag ncig, ua rau lawv yog qhov kev xaiv zoo rau cov nroog thiab cov thawj coj chaw nrhiav kev daws teeb meem ruaj khov.
Kev tshuaj xyuas sib piv:
Yuav kom nkag siab zoo dua txog qhov sib txawv ntawm peb cov ntaub ntawv sab hauv, peb muab piv rau lawv raws li cov yam ntxwv tseem ceeb:
1. Kev tiv thaiv tshuaj lom neeg:
Cov yeeb nkab uas muaj cov polypropylene ua tau zoo heev hauv qhov no, muab kev tiv thaiv zoo heev rau ntau yam tshuaj lom neeg. Cov yeeb nkab uas muaj cov polyurethane kuj tiv taus zoo, tab sis lawv cov tshuaj tiv thaiv tsis tshua muaj. Cov ntaub epoxy sewer muaj kev tiv thaiv tshuaj zoo heev.
2. Kev tiv thaiv hnav:
Cov yeeb nkab uas muaj txheej polyurethane tiv taus kev sib txhuam zoo heev, ua rau nws zoo tagnrho rau cov kev siv hauv cov kav dej phwj uas raug kev sib txhuam. Cov yeeb nkab uas muaj txheej polypropylene tiv taus kev sib txhuam nruab nrab, thaum cov txheej epoxy tsis tau tsim tshwj xeeb los tiv taus kev sib txhuam thiab kev puas tsuaj loj heev.
3. Kev yooj yim rau kev teeb tsa:
Cov yeeb nkab uas muaj txheej polypropylene muab kev ywj pheej thaum lub sijhawm teeb tsa vim nws cov khoom sib xyaw ua ke tsis hnyav. Cov yeeb nkab uas muaj txheej polyurethane muaj kev ywj pheej nruab nrab, thaum cov epoxy sewer liners muaj kev ruaj khov dua thiab xav tau cov txheej txheem siv kom raug.
Xaus lus:
Kev xaiv cov khoom siv sab hauv kom zoo rau cov kav dej phwj yog qhov tseem ceeb rau kev ua kom lub kaw lus ua haujlwm tau zoo, siv tau ntev thiab siv tau nyiaj tsawg. Txawm hais tias txhua yam khoom muaj cov txiaj ntsig tshwj xeeb, qhov kev xaiv kawg nyob ntawm qhov xav tau tshwj xeeb ntawm koj lub kaw lus phwj. Cov kav dej polypropylene muaj cov tshuaj tiv thaiv zoo heev, cov kav dej polyurethane muaj cov tshuaj tiv thaiv zoo heev, thiab cov kav dej phwj epoxy ua haujlwm zoo rau cov haujlwm kho dua tshiab. Kev nkag siab txog cov txiaj ntsig thiab kev txwv ntawm txhua yam khoom ua rau cov neeg txiav txim siab txiav txim siab tau zoo kom ntseeg tau tias lub kaw lus phwj siv tau ntev thiab ua haujlwm tau zoo tshaj plaws.
