Kuyerekeza kwa zida zitatu zozizirira bwino: Ndi iti yabwino kwambiri?

Mabokosi ozizira amagwiritsidwa ntchito kwambiri pamoyo watsiku ndi tsiku. Kaya amagwiritsidwa ntchito paulendo, kusodza kuthengo, kusonkhanitsa abwenzi, kunyamula mankhwala, kapena kunyamula zinthu zatsopano, ndikofunikira kusankha mabokosi oyenera posankha bokosi lotsekeredwa.

Izi ndi zingapo wamba insulated bokosi zipangizo ndi makhalidwe awo:

PU (polyurethane)

Mabokosi a PU ozizira komanso otentha amakhala ndi magwiridwe antchito abwino kwambiri otenthetsera, kuchuluka kwa ma cell otsekedwa, ndipo amatha kupewa kutengera kutentha. Kuphatikiza apo, zinthu za PU zilinso ndi mphamvu zabwino komanso zolimba, zimatha kupirira kupsinjika ndi kukhudzidwa kwina, ndipo sizosavuta kupunduka kapena kuwonongeka.

Komabe, mtengo wacmabokosi a ooler opangidwa ndi PU ndi okwera kwambiri, zomwe zingachepetse kugwiritsa ntchito kwake pazinthu zina zotsika mtengo.

EPS (polystyrene thovu)

Zinthu za EPS ndizosankha wamba komanso zotsika mtengo zotsika mtengo, zopepuka, komanso zosavuta kunyamula ndikugwiritsa ntchito. Ndizoyenera pazithunzi zina pomwe zofunikira zotchingira sizokwera kwambiri ndipo bajeti ndi yochepa.

Kutentha kwamafuta azinthu za EPS ndikocheperako, sikukondera kwambiri zachilengedwe, komanso kovuta kutsitsa.

EPP (polypropylene thovu zinthu)

Zinthu za EPP zili ndi kukana kwamphamvu kwa seismic komanso kukana kwamphamvu, zomwe zimatha kuteteza bwino zinthu zomwe zili m'bokosi. Zinthu za EPP ndizogwirizana ndi chilengedwe komanso sizowopsa, zimatha kugwiritsidwanso ntchito komanso zimagwiritsidwanso ntchito, ndipo zimakwaniritsa zofunikira zoteteza chilengedwe masiku ano.

Nthawi zambiri mtengo wazinthu za EPP nthawi zambiri umakhala wokwera kuposa wazinthu za EPS.

Kuyerekeza kwathunthu, zinthu za PU (polyurethane) zimakhala ndi ntchito yabwino kwambiri yotchinjiriza. Kuchuluka kwa maselo otsekedwa komanso kutsekemera kwabwino kwa kutentha kumachititsa kuti kutentha kwa zinthu zomwe zili m'bokosi kukhale kosasunthika panthawi yoyenda mtunda wautali, ndipo ndi koyenera chakudya ndi mankhwala omwe amafunika kusungidwa kutentha kochepa.
