Polypropylene PP granules zinthu pulasitiki katundu

Kufotokozera mwachidule:

Polypropylenendi polima wopezedwa powonjezera polymerization wa propylene.Ndi zinthu zoyera za waxy zowoneka bwino komanso zopepuka.Mankhwalawa ndi (C3H6)n, kachulukidwe ndi 0.89 ~ 0.91g/cm3, Imatha kuyaka, malo osungunuka ndi 189 ° C, ndipo amafewa pafupifupi 155 ° C.Kutentha kwa ntchito ndi -30 ° 140 ° C.Imagonjetsedwa ndi dzimbiri ndi asidi, alkali, njira ya mchere ndi zosungunulira zosiyanasiyana za organic pansi pa 80 °C, ndipo zimatha kuwola ndi kutentha kwambiri ndi okosijeni.

PP pa 25

Kugwiritsa ntchito

Polypropylene chimagwiritsidwa ntchito kupanga zovala, zofunda ndi zinthu zina CHIKWANGWANI, zipangizo zachipatala, magalimoto, njinga, mbali, mapaipi mayendedwe, muli mankhwala, etc., komanso ntchito ma CD chakudya ndi mankhwala.

MALANGIZO

Polypropylene, yofupikitsidwa ngati PP, ndi chinthu cholimba chopanda mtundu, chosanunkhiza, chosakhala poizoni, chosasunthika.

(1) Polypropylene ndi thermoplastic synthetic resin yomwe imagwira ntchito bwino kwambiri, yomwe ndi pulasitiki yopanda utoto komanso yowoneka bwino ya thermoplastic yopepuka yopepuka-cholinga chonse.Lili ndi kukana kwa mankhwala, kukana kutentha, kutsekemera kwa magetsi, mphamvu zamakina apamwamba kwambiri komanso katundu wabwino kwambiri wosagwira ntchito, ndi zina zotero, zomwe zimapangitsa kuti polypropylene igwiritsidwe ntchito mofulumira m'makina, magalimoto, zipangizo zamagetsi, zomangamanga, nsalu, ma CD kuyambira pachiyambi.Zapangidwa mochuluka ndikugwiritsidwa ntchito m'madera ambiri monga ulimi, nkhalango, nsomba ndi mafakitale a chakudya.

(2) Chifukwa cha pulasitiki yake, zipangizo za polypropylene zimasintha pang'onopang'ono zinthu zamatabwa, ndipo mphamvu zambiri, kulimba komanso kukana kuvala kwambiri zasintha pang'onopang'ono ntchito zamakina azitsulo.Kuphatikiza apo, polypropylene ili ndi ntchito zabwino zomangira ndi kuphatikizira, ndipo imakhala ndi malo akulu ogwiritsira ntchito konkriti, nsalu, zonyamula ndi ulimi, nkhalango ndi usodzi.

THUPI

Polypropylene ili ndi zinthu zambiri zabwino:

1. Kuchulukana kwachibale ndi kochepa, kokha 0.89-0.91, yomwe ndi imodzi mwa mitundu yopepuka kwambiri mu mapulasitiki.

2. Zinthu zamakina zabwino, kuwonjezera pa kukana kwamphamvu, zida zina zamakina ndizabwino kuposa polyethylene, kuumba kwabwino.

3. Ndi kukana kutentha kwakukulu, kutentha kosagwiritsidwa ntchito kosalekeza kumatha kufika 110-120 ℃.

4. Good mankhwala katundu, pafupifupi palibe mayamwidwe madzi, palibe anachita ndi mankhwala ambiri.

5. Kapangidwe koyera, kopanda poizoni.

6. Kutsekemera kwamagetsi kwabwino.

7. Kuwonekera kwa zinthu za polypropylene ndikwabwino kuposa zomwe zili ndi polyethylene yapamwamba kwambiri.

50 / ng'oma, 25kg / ng'oma kapena makonda malinga ndi zopempha kasitomala wa.

Kuphatikiza pa izi, zinthu zathu zotchuka ndizokuyendayenda kwa fiberglass, magalasi a fiberglass,ndisera yotulutsa nkhungu.Imelo ngati kuli kofunikira.
