mankhwala

Polypropylene Copolymer Sinopec Qilu,
PP utomoni kwa zingwe, PP utomoni wa malamba chikwama matani, PP utomoni kwa matumba nsalu,

Polypropylene ndi utomoni wopangidwa ndi polymerization wa propylene (CH3—CH = CH2) ndi H2 monga molecular weight modifier.Pali ma stereomer atatu a PP - isotactic, atactic ndi syndiotactic.PP ilibe magulu a polar ndipo ili ndi zida zabwino kwambiri zotchinjiriza magetsi.Mayamwidwe ake amadzi ndi ochepera 0.01%.PP ndi polima theka-crystalline ndi kukhazikika kwa mankhwala.Ndiwokhazikika kumankhwala ambiri kupatula ma oxidizer amphamvu.Ma inorganic acid, alkali ndi mchere sakhala ndi vuto lililonse pa PP.PP imakhala ndi kutentha kwabwino komanso kutsika kochepa.Malo ake osungunuka ndi pafupifupi 165 ℃.Ili ndi mphamvu zolimba kwambiri komanso kulimba kwapamtunda komanso kukana kupsinjika kwa chilengedwe.Imatha kupirira 120 ℃ mosalekeza.

Sinopec ndiye wopanga wamkulu wa PP ku China, mphamvu yake ya PP ndi 45% ya mphamvu zonse mdzikolo.Kampaniyi pakadali pano ili ndi 29 PP zomera ndi ndondomeko mosalekeza (kuphatikiza amene akumangidwa).Matekinoloje omwe amagwiritsidwa ntchito ndi mayunitsiwa akuphatikiza njira ya Mitsui Chemical's HYPOL, njira ya gasi ya Amoco, njira ya Basell's Spheripol ndi Spherizone ndi njira yamafuta a Novolen.Ndi luso lake lamphamvu lofufuza zasayansi, Sinopec yapanga paokha njira yachiwiri yopangira PP.

Zithunzi za PP

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

2.good makina katundu, kuwonjezera kukana zimakhudza, katundu wina makina ndi bwino kuposa polyethylene, akamaumba processing ntchito bwino.

3.Ili ndi kukana kutentha kwakukulu ndipo kutentha kosagwiritsidwa ntchito kosalekeza kumatha kufika 110-120 °C.

4.zabwino mankhwala katundu, pafupifupi palibe mayamwidwe madzi, ndipo sachita ndi mankhwala ambiri.

5.kapangidwe kake ndi koyera, kopanda poizoni.

6.electrical insulation ndi yabwino.

Nthawi zambiri amagwiritsidwa ntchito pa kalasi ya PP

Kugwiritsa ntchito

Phukusi

PP yoperekedwa ndi kampani yathu ndi kalasi yojambulira waya, kalasi ya copolymer, ndi kalasi yojambula waya imagwiritsidwa ntchito kwambiri pamakampani opanga pulasitiki, matumba oluka, malamba a tani, zingwe, ndi zina zotero, ndipo angagwiritsidwe ntchito mu jekeseni wa PP. mafakitale, magawo, makapu, etc.
Polypropylene Copolymer amagwiritsidwa ntchito kwambiri popanga zinthu zamakampani, monga ma dashboards, mkati mwagalimoto, ma bumpers agalimoto, mbali zamkati ndi kunja kwa makina ochapira, zotengera za batire ndi akasinja amadzi.Itha kugwiritsidwanso ntchito kupanga zinthu zapakhomo monga mipando, zoseweretsa, masutukesi ndi zotengera zosiyanasiyana.
