Ubwino Wogwiritsa Ntchito EPP Material mu Fresh Air Ventilation Systems

Kodi zinthu za EPP ndi chiyani?

EPP ndiye chidule cha polypropylene yowonjezera, mtundu watsopano wa pulasitiki wa thovu.EPP ndi polypropylene pulasitiki thovu zakuthupi, amene ndi mkulu-ntchito mkulu crystalline polima/gesi gulu zinthu.Ndi magwiridwe ake apadera komanso opambana, yakhala mtundu watsopano wokonda zachilengedwe womwe ukukula mwachangu komanso wokonda zachilengedwe.Pakadali pano, EPP ndi chinthu chogwirizana ndi chilengedwe chomwe chimatha kubwezeretsedwanso, kuonongeka mwachilengedwe, ndipo sichimayambitsa kuipitsa koyera.

Kodi mawonekedwe a EPP ndi ati?

Monga mtundu watsopano wa pulasitiki thovu, EPP ali ndi makhalidwe kuwala yeniyeni yokoka, elasticity wabwino, kukana mantha ndi psinjika kukana, mkulu mapindikidwe kuchira mlingo, ntchito mayamwidwe bwino, kukana mafuta, kukana asidi, kukana alkali, kukana zosiyanasiyana zosungunulira mankhwala, mayamwidwe sanali madzi, kutchinjiriza, kutentha kukana (-40 ~ 130 ℃), sanali poizoni ndi zoipa.Itha kusinthidwanso 100% ndipo ilibe kuwonongeka kwa magwiridwe antchito.Ndi pulasitiki ya thovu yochezeka kwenikweni.Mikanda ya EPP imatha kupangidwa kukhala mawonekedwe osiyanasiyana azinthu za EPP mu nkhungu yamakina omangira.

Ubwino wogwiritsa ntchito ndi chiyaniEPP mumakina a mpweya wabwino?

1. Kutsekemera kwa phokoso ndi kuchepetsa phokoso: EPP ili ndi mphamvu yabwino yotsekemera, yomwe ingachepetse phokoso la makina.Phokoso la mpweya wabwino pogwiritsa ntchito zinthu za EPP lidzakhala locheperapo;

2. Insulation ndi anti-condensation: EPP ili ndi mphamvu yabwino kwambiri yotetezera, yomwe ingateteze bwino kutsekemera kapena kutsekemera mkati mwa makina.Kuphatikiza apo, palibe chifukwa chowonjezera zida zotchinjiriza mkati mwa makina, zomwe zimatha kugwiritsa ntchito bwino malo amkati ndikuchepetsa kuchuluka kwa makina;

3. Kulimbana ndi zivomezi ndi kuponderezedwa: EPP imakhala ndi mphamvu yolimbana ndi zivomezi ndipo imakhala yolimba kwambiri, yomwe ingapewe kuwonongeka kwa galimoto ndi zigawo zina zamkati panthawi yoyendetsa;

4. Wopepuka: EPP ndi yopepuka kwambiri kuposa zigawo zapulasitiki zomwezo.Palibe chitsulo chowonjezera chachitsulo kapena chimango cha pulasitiki chomwe chimafunikira, ndipo popeza mapangidwe a EPP amapangidwa ndi zida zogaya, kuyika kwazinthu zonse zamkati ndizolondola kwambiri.
