Yas-coated steel yeeb nkab yog cov yeeb nkab uas feem ntau siv nrog kev ua haujlwm siab corrosion thiab ua haujlwm ntev. Cov kav dej yas-coated steel tuaj yeem raug cais raws li cov khoom siv sib txawv thiab cov kev xav tau siv.
Kev faib tawm ntawm cov yas coated steel kav
Raws li cov txheej txheem sib txawv thiab cov kev xav tau siv, cov kav dej yas-coated steel tuaj yeem muab faib ua ntau hom:
1. Polyethylene yas-coated steel yeeb nkab (PE yas-coated steel yeeb nkab)
Polyethylene-coated steel yeeb nkab yog cov yeeb nkab coated nrog high-density polyethylene (HDPE). Lub thickness ib txwm ntawm cov yeeb nkab no yog 3-4mm, nws tuaj yeem tiv taus dej siab thiab cua siab, muaj kev tiv thaiv corrosion zoo thiab lub neej ntev.

2. Epoxy coated steel yeeb nkab
Epoxy-coated steel yeeb nkab yog cov yeeb nkab coated nrog epoxy resin. Cov yeeb nkab zoo li no muaj qhov nyuaj thiab lub zog thiab tuaj yeem tiv taus siab thiab cuam tshuam, yog li nws tau siv dav hauv kev lag luam chemical, marine thiab roj av.

3. Polyvinyl chloride yas-coated steel yeeb nkab (PVC yas-coated steel yeeb nkab)
PVC-coated steel yeeb nkab yog cov yeeb nkab coated nrog polyvinyl chloride. Cov yeeb nkab zoo li no muaj kev tiv thaiv corrosion zoo thiab thermal stability, thiab yog pheej yig, yog li nws yog dav siv hauv dej, dej, hluav taws xob thiab lwm yam kev lag luam.
Qhov zoo ntawm cov yas-coated steel kav
1. Muaj zog corrosion kuj
Thaum lub sij hawm tsim cov yas-coated steel kav, qhov saum npoo ntawm cov yeeb nkab steel yog coated los cais cov yeeb nkab los ntawm ib puag ncig sab nraud, yog li tiv thaiv cov yeeb nkab steel kom tsis txhob muaj kab mob los yog corroded. Qhov no ua kom lub neej ua haujlwm thiab kev nyab xeeb ntawm cov kav dej yas-coated steel.
2. Lub neej ntev
Cov txheej txheej yas muaj qhov zoo adhesion thiab hardness, uas tsis tsuas yog tiv thaiv cov yeeb nkab steel los ntawm kev puas tsuaj rau sab nraud, tab sis kuj tiv thaiv cov teeb meem xws li infarction ntawm cov phab ntsa hauv cov yeeb nkab, yog li ncua kev pab cuam lub neej ntawm cov yeeb nkab. Raws li kev txheeb cais, kev pabcuam lub neej ntawm cov kav dej yas-coated steel tuaj yeem ncav cuag ntau dua 20 xyoo, thiab lawv tuaj yeem tuav tau zoo nyob rau qee qhov chaw hnyav.
