mankhwala

PP utomoni kwa ma CD,
zachipatala, kuwala CHIKWANGWANI chingwe, PP utomoni ntchito galimoto,

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

Mu thumba la 25kg, 16MT mu 20fcl imodzi yopanda phale kapena 26-28MT mu 40HQ imodzi yopanda phale kapena thumba la jumbo la 700kg, 26-28MT mu 40HQ imodzi yopanda phale.

Polypropylene si poizoni, odorless, zoipa yamkaka woyera mkulu crystallization polima, ndi imodzi mwa mitundu opepuka mapulasitiki onse panopa, formability wabwino, mankhwala pamwamba luster, kukana kutentha, kukana dzimbiri, mankhwala kupezeka nthunzi disinfection ndi ubwino waukulu wa polypropylene. .

Zopangira zazikulu za polypropylene ndi propylene, yomwe imapangidwa makamaka kuchokera ku naphtha, methanol ndi propane.

Malinga ndi ziwerengero, pofika kumapeto kwa 2018, panali mabizinesi opitilira 160 a propylene ku China, omwe amatha kupanga matani pafupifupi 32.3 miliyoni pachaka ndi matani pafupifupi 27.1 miliyoni, kukula kwa chaka ndi chaka pafupifupi 2.26 %.

Mtengo wa propylene umakhudzidwa osati kokha ndi mtengo wamafuta osakanizidwa, methanol, propane, komanso ndi mgwirizano wamsika komanso wofunikira.

Mtundu uwu wa zinthu zopangira mankhwala zomwe zimagwiritsidwa ntchito kwambiri pakuluka pulasitiki, kulongedza, galimoto,zachipatala, kuwala CHIKWANGWANI chingwendi madera ena, mu chitukuko chatsopano cha mafakitale, kukweza, padzakhala zofunikira zatsopano.

Ndi chitukuko chosalekeza cha chuma chathu, makampani opanga pulasitiki akupereka njira yatsopano yofunira "functionalization", "yopepuka" ndi "micro-molding", yomwe imayendetsa kukula kokhazikika kwa kufunikira kwa jekeseni wowonda-khoma, copolymerization. , CHIKWANGWANI ndi zinthu zina za polypropylene.
