Pulasitiki thovu

Styrofoam ndi mtundu wa pulasitiki wopezedwa ndi njira zakuthupi kapena zamankhwala kuti apange ma cell cell mkati mwa pulasitiki.Pulasitiki iyi ili ndi ubwino wolemera pang'ono, kutsekereza kutentha, kusunga, kutsekemera, kuteteza dzimbiri komanso mtengo wotsika.Pafupifupi mapulasitiki onse a thermosetting ndi thermoplastic amatha kupanga thovu.Zithovu zodziwika bwino ndi polystyrene, polyurethane ndi polyolefin.

Chiyambi cha thovu polypropylene

Foamed polypropylene (foamed polypropylene) ndi mtundu wa pulasitiki wokhala ndi thovu wopangidwa ndi utomoni wa polypropylene.Poyerekeza ndi mapulasitiki okhala ndi thovu omwe amagwiritsidwa ntchito kwambiri, polypropylene yokhala ndi thovu ili ndi zabwino zambiri.

Pakadali pano, omwe amapanga zida zopangira mphamvu zambiri za polypropylene akuphatikizapo Basell, Borealis, Dow Chemical, Samsung, ExxonMobil ndi zina zotero.Opanga ukadaulo wa polypropylene thovu akuphatikizapo JSP, Kaneka, BASF ndi Berstorff.Mabungwe ambiri ofufuza zapakhomo achita kafukufuku wambiri pakuchita thovu, ndipo opanga ena azindikiranso kupanga mafakitale, monga Zhenhai Oil Refinery, Yanshan Petrochemical Resin Research Institute, Wuhan Futia, ndi zina zambiri, koma pakadali kusiyana kwakukulu pazogulitsa. khalidwe poyerekeza ndi mayiko akunja.

Ntchito mundawo thovu polypropylene

1. Kuyika chakudya

Polypropylene yokhala ndi thovu imakhala ndi kuwonongeka kwabwino komanso kukana kwamafuta, zomwe zimapatsa mwayi wosiyana ndi ufa wowonjezera wa polystyrene pamsika wogwiritsa ntchito kamodzi.

2. Kuteteza kutentha

Foam polypropylene zakuthupi ndi mtundu watsopano wazinthu zotenthetsera zotenthetsera zokhala ndi kutentha kwambiri.Nthawi zambiri imatha kupirira kutentha kwa -40 ℃ ~ 110 ℃, ndipo imatha kupirira kutentha kwa 130 ℃ kwakanthawi kochepa.

3. Makampani opanga magalimoto

M'zaka zaposachedwa, kugwiritsa ntchito thovu la polypropylene pamagalimoto akukulirakulira, zomwe zingachepetse kwambiri kulemera kwa magalimoto ndikupulumutsa mafuta.

4. Malo omanga

Zida zoteteza madzi, zinthu zotchingira pansi, zakunja zotchinjiriza khoma

5. Kupaka pakompyuta

6. Kuyika kwa bafa

7. Katundu wamasewera

8.Zidole

Pofuna kukwaniritsa zofuna za msika, Hangzhou Fuyang D&T Co., Ltd malinga ndi zosowa zosiyanasiyana za msika, kupanga mitundu yosiyanasiyana ya makina odulira thovu, omwe amagwiritsidwa ntchito kwambiri podula makina ofewa ofewa opukutira, makina ampheni, kudula tebulo lolimba thovu. ndi theka lolimba la thovu makina opangira mpeni, komanso kudulaEPS wodula.
