Insulated yeeb nkab - nta

1. Muaj zog corrosion kuj thiab muaj peev xwm tsis muaj dej, nrog rau cov nqi qis.
Raws li kev kwv yees los ntawm cov tuam tsev muaj feem cuam tshuam, ob lub yeeb nkab cua sov feem ntau txo cov nqi ntawm qhov project los ntawm ib puag ncig 25% (thaum siv fiberglass ua txheej tiv thaiv) thiab kwv yees li 10% (thaum siv cov polyethylene high-density li txheej tiv thaiv).

2. Tsawg kub poob, txuag hluav taws xob. Thaum tshav kub kub poob tsuas yog 25% ntawm cov khoom siv yeeb nkab.
Direct-faus insulated kav dej muaj thermal conductivity ntawm 0.022 kcal/mh degree thiab ib tug dej nqus tus nqi ntawm 0.03 kg/cm³.

3. Lub neej ua haujlwm ntev.
Kev txhim kho thiab siv tau zoo tuaj yeem txuas lub network lub neej ntev mus rau 30-50 xyoo, nrog cov nqi kho tsawg.

4. Kev ua haujlwm hauv av tsawg, kev tsim kho sai, muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig.
tuaj yeem txo qhov ntim ntawm qhov khawb los ntawm ntau dua 50% thiab txo cov pob zeb thiab pob zeb siv los ntawm 90%.
