Zatsopano pamakampani opanga thovu |Ukadaulo wa IMPFC umapangitsa kuti magawo a thovu aziwoneka bwino!

Expanded polypropylene (EPP mwachidule) ndi tinthu tating'onoting'ono tating'onoting'ono tating'ono tating'ono ta thermoplastic totengera thovu la polypropylene.Ndi yakuda, yapinki kapena yoyera, ndipo m'mimba mwake nthawi zambiri imakhala pakati pa φ2 ndi 7mm.Mikanda ya EPP imapangidwa ndi magawo awiri, olimba ndi gasi.Nthawi zambiri, gawo lolimba limangotengera 2% mpaka 10% ya kulemera konse, ndipo ena onse ndi gasi.Chiwerengero chochepa cha kachulukidwe ndi 20-200 kg / m3.Makamaka, kulemera kwa EPP ndi kopepuka kuposa kwa thovu la polyurethane pansi pa mphamvu yomweyo yotengera mphamvu.Chifukwa chake, mbali za thovu zopangidwa ndi mikanda ya EPP ndizolemera pang'ono, zimakhala ndi kutentha kwabwino, zotchingira bwino komanso zida zamakina zabwino kwambiri, ndipo zimatha kuwonongeka 100% ndikubwezerezedwanso.Ubwino wonsewu umapangitsa EPP kukhala imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri m'magawo ambiri, m'mbali zonse za moyo wathu:

M'munda wamagalimoto, EPP ndiye njira yabwino kwambiri yokwaniritsira zinthu zopepuka, monga ma bumpers, zowongolera zamagalimoto A-pillar, zida zamagalimoto zam'mbali, zitseko zamagalimoto, mipando yamagalimoto apamwamba, mabokosi a zida, mitengo ikuluikulu, malo opumira, zida za Foamed polypropylene. angagwiritsidwe ntchito mbali monga pansi mbale, dzuwa visor ndi gulu chida.Deta yowerengera: Pakali pano, pafupifupi pulasitiki yomwe imagwiritsidwa ntchito pamagalimoto ndi 100-130kg/galimoto, pomwe kugwiritsa ntchito thovu la polypropylene ndi 4-6kg/galimoto, zomwe zimatha kuchepetsa kulemera kwa magalimoto ndi 10%.

Pankhani yolongedza, zotengera zomwe zimatha kugwiritsidwanso ntchito ndi zonyamula zopangidwa ndi EPP zimakhala ndi mawonekedwe osungira kutentha, kukana kutentha, kukana dzimbiri, kutchinjiriza, moyo wautali wautumiki, ndi zina zotere, zilibe zinthu zomwe zimasokonekera, sizikhala ndi zinthu zomwe zili zowononga ozoni wosanjikiza kapena zitsulo zolemera Zakuthupi ma CD, akhoza digested pambuyo Kutentha, 100% zachilengedwe wochezeka.Kaya ndi zida zamagetsi zolondola, kapena kutumiza zipatso, nyama yowunda, ayisikilimu ndi zakudya zina, thovu la polypropylene lingagwiritsidwe ntchito.Malinga ndi mayeso a kupsinjika kwa BASF, EPP imatha kukwaniritsa maulendo 100 kapena kupitilira apo, zomwe zimapulumutsa kwambiri zida ndikuchepetsa mtengo wolongedza.
