Mafotokozedwe Akatundu
Homopolymer polypropylene ndi polima wopangidwa ndi polymerization wa propylene monoma yekha.Homopolymer polypropylene ndi semi crystalline polima.Chifukwa cha kuwala kwake kwakukulu, homopolymer polypropylene ili ndi makina abwino kwambiri.Kuphatikizira kukhazikika kwakukulu, kulimba kwamphamvu kwambiri, kukana kutentha kwabwino komanso kupindika.Panthawi imodzimodziyo, chifukwa cha madzi ake abwino, kutentha kwapamwamba kwa crystallization kumachepetsa kuumba kwazinthu.Homopolymer polypropylene chimagwiritsidwa ntchito jekeseni, kujambula ndi zina processing ndi akamaumba njira.

Mapulogalamu
Kuchuluka kwa homopolymer polypropylene:
1. Extrusion akamaumba: mapaipi, mbale, mapepala, etc.
2. jekeseni akamaumba: mitundu yonse ya nkhonya ndi Chalk, kuphatikizapo zotengera chakudya, zipangizo zapakhomo, zipolopolo kunyumba chipangizo, etc.
3. Thermoforming: tableware disposable, kuphatikizapo nkhomaliro mabokosi, mbale ndi mbale, makapu chakumwa, etc.
4. Kanema: Kanema wa Homopolymer polypropylene ndi wowoneka bwino komanso wonyezimira, wokhala ndi mpweya wocheperako ku nthunzi wamadzi, kuphatikiza filimu yowombedwa, filimu yoponyedwa, filimu yowonjezera ya bidirectional, ndi zina zotero.
5. Kujambula: ulusi wathyathyathya ukhoza kupangidwa ndi madzi ochepa, ndipo ulusi wamagulu ndi nsalu zopanda nsalu zimatha kupangidwa ndi madzi ambiri.
CHIKWANGWANI ndiye msika waukulu wa polypropylene.Kutambasula kapena kuwongolera kumatha kukulitsa mphamvu yamphamvu ndi nthawi 15.Zogulitsa za silika, kuphatikizapo zovala, matewera ndi zosawomba, ndizo zida zazikulu zopangira masks azachipatala Chikopa Chachikopa, Matumba a Ulimi, Zingwe, Zovala Zophimba Pansi ndi Malamba.Kapeti ndi kapeti kumbuyo kumudzi.PP imathanso kuponyedwa kapena kutambasulidwa molunjika kukhala mafilimu.Mafilimu owongolera amatha kugwiritsidwa ntchito ngati ndudu.Zida zonyamula maswiti ndi zolemba zambiri;Kanema wosakhazikika amagwiritsidwa ntchito ngati ma capacitor kapena zida zoyikamo pepala la PP limagwiritsidwa ntchito popanga zotengera zakudya zotenthetsera, ndipo mawonekedwe ake otsimikizira chinyezi, kufalitsa mpweya komanso kutulutsa fungo ayenera kutsatira malamulo a FDA.
