EPE (ExpandableClimatic Tests) ndi polyethylene yochotsedwa, yomwe imadziwikanso kuti ubweya wa ngale.Ma cell otsekedwa osalumikizana, ndi chinthu chopangidwa ndi thovu la polyethylene chopangidwa ndi kutulutsa kwa polyethylene otsika (LDPE) ngati chinthu chachikulu.
EPE ali ndi elasticity mkulu ndi maonekedwe woyera.Chifukwa ndi thupi lodziyimira palokha, ndi lopepuka ndipo limatha kupindika, motero limakhala ndi zotsatira zobalalitsa ndi kubisa mphamvu yamphamvu.Kuonjezera apo, EPE imakhalanso ndi makhalidwe osungira kutentha, kutentha kwa chinyezi, kutentha kwa kutentha, kutsekemera kwa phokoso, kutsutsa-kumenyana, kukalamba, kukana kwa dzimbiri ndi zina zotero.Ubwino umenewu umapangitsa kuti thonje la EPE ngale pang'onopang'ono lilowe m'malo mwa zida zonyamula zachikhalidwe, zomwe zimagwiritsidwa ntchito m'magulu onse a moyo poletsa kugwa, kugunda, kunyamula katundu.
EPE kupanga ndondomeko ndi luso
Kupanga kwa EPE kumaphatikizapo magawo atatu: gawo la thonje la ngale, gawo lakuya la thonje la ngale ndi thumba la thonje la ngale.Kuphatikiza apo, gawo lililonse limakhala ndi tizigawo tating'onoting'ono, monga tawonera pansipa:
1. Ngale thonje mpukutu zakuthupi gawo
Polyethylene gelatin kudya →
kutentha kwakukulu kumatulutsa thovu →
extrusion → kukulitsa → kubwezeretsanso → kuyika & kusunga (kuchiritsa)
