Taw qhia
Cov kav hlau hlau tau siv dav hauv ntau yam kev lag luam rau ntau xyoo. Txawm li cas los xij, nrog kev txhim kho thev naus laus zis thiab kev tshwm sim ntawm cov ntaub ntawv tshiab, cov kav hlau steel tau maj mam hloov los ntawm lwm cov ntaub ntawv. Hauv tsab xov xwm no, peb yuav tham txog qee yam ntawm cov khoom siv uas hloov cov kav hlau steel thiab qhov zoo ntawm cov ntaub ntawv no.
Vim li cas cov kav hlau raug hloov?
Cov kav hlau steel muaj ntau qhov tsis zoo, nrog rau kev ua rau corrosion thiab xeb. Lawv kuj hnyav heev, uas ua rau lawv nyuaj rau kev thauj thiab nruab. Tsis tas li ntawd, cov kav dej steel tsis haum rau qee qhov kev siv, xws li cov uas yuav tsum tau ua kom yooj yim los yog ua haujlwm rau qhov kub thiab txias. Yog li ntawd, ntau lub lag luam tab tom nrhiav lwm cov khoom siv los hloov cov kav hlau.
Alternatives rau steel kav
1. PVC kav
Cov kav dej PVC (polyvinyl chloride) tau siv los hloov cov kav hlau. Cov kav dej PVC muaj ntau qhov zoo dua cov kav hlau, nrog rau kev sib sib zog nqus, corrosion-resistant, thiab yooj yim rau nruab. Lawv kuj muaj lub neej ntev dua li cov kav dej steel, vim tias lawv tsis cuam tshuam rau xeb lossis xeb.
2. Cov kav dej HDPE
HDPE (high-density polyethylene) kav yog lwm cov khoom siv los hloov cov kav hlau. HDPE kav yog lub teeb yuag, hloov tau, thiab tiv taus corrosion thiab tshuaj lom neeg. Lawv kuj yog ib qho yooj yim rau nruab thiab muaj lub neej ntev dua li cov kav dej steel.
3. Cov kav dej fiberglass
Fiberglass kav kuj tau siv los ua lwm txoj hauv cov kav hlau. Fiberglass kav yog lub teeb yuag, corrosion-resistant, thiab muaj lub neej ntev dua li cov kav hlau. Lawv kuj hloov tau, uas ua rau lawv haum rau cov ntawv thov uas yuav tsum tau yooj.
4. Cov kav dej tooj liab
Cov kav dej tooj liab yog lwm cov khoom siv los hloov cov kav hlau. Cov kav dej tooj liab tiv taus corrosion, hnav, thiab yooj yim rau nruab. Lawv kuj muaj lub neej ntev dua li cov kav dej steel.
Qhov zoo ntawm kev siv lwm cov ntaub ntawv
1. Corrosion-resistant
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv lwm cov khoom siv rau cov kav dej steel yog tias lawv muaj corrosion-resistant. Qhov no txhais tau hais tias lawv tsis xeb los yog corrode, uas ua rau kom lawv cov lifespan thiab txo nqi txij nkawm.
2. Lub teeb yuag
Ntau lwm cov ntaub ntawv rau cov kav hlau steel yog lub teeb yuag, uas ua rau lawv yooj yim rau kev thauj thiab nruab. Qhov no txuag lub sijhawm thiab txo cov nqi installation.
3. Yooj yim
Qee lwm cov ntaub ntawv, xws li fiberglass thiab tooj liab kav, yog hloov tau, uas ua rau lawv haum rau cov kev siv uas yuav tsum tau yooj. Qhov no txhais tau hais tias lawv tuaj yeem ntsia tau rau hauv thaj chaw uas cov kav hlau tsis haum.
4. Lub neej ntev
Lwm cov khoom siv rau cov kav hlau steel feem ntau muaj lub neej ntev dua li cov kav hlau. Qhov no txhais tau hais tias lawv tsis tas yuav tsum tau hloov ntau zaus, uas txo cov nqi txij nkawm thiab kev poob qis.
Xaus
Hauv kev xaus, cov yeeb nkab steel tau raug hloov los ntawm lwm cov ntaub ntawv rau ntau yam, nrog rau qhov tseeb tias lawv muaj feem cuam tshuam rau corrosion thiab xeb, hnyav, thiab tsis haum rau qee qhov kev siv. PVC kav, HDPE kav, fiberglass kav, thiab tooj liab kav yog ib co ntawm cov khoom siv los hloov cov kav hlau. Cov ntaub ntawv no muaj ntau yam zoo, nrog rau kev ua kom corrosion-resistant, hnav, yoog raws, thiab muaj lub neej ntev dua li cov kav dej steel. Kev siv lwm cov ntaub ntawv no yog nce, raws li kev lag luam nrhiav txoj hauv kev los txhim kho kev ua tau zoo thiab txo cov nqi tu.
