Note: Ngati mukufuna kudziwa zambiri zam'mapulasitiki: chidziwitso cha pulasitiki-zopangira

Pulasitiki ndi chinthu chomwe timakonda kugwiritsa ntchito pamoyo wathu watsiku ndi tsiku. Zing'onozing'ono ngati matumba apulasitiki, mabotolo a ana, mabotolo a zakumwa, mabokosi a nkhomaliro, zokutira pulasitiki, zazikulu ngati filimu yaulimi, mipando, zida zamagetsi, kusindikiza kwa 3D, ngakhale maroketi ndi zoponya, mapulasitiki onse alipo.

Pulasitiki ndi nthambi yofunika kwambiri yama polima opangidwa ndi mitundu yambiri, yokhala ndi mitundu yambiri, zokolola zazikulu komanso ntchito zambiri. Kwa ma pulasitiki osiyanasiyana, amatha kusankhidwa motere:

1. Malinga ndi machitidwe akamatenthedwa, mapulasitiki amatha kugawidwa kukhala ma thermoplastics ndi ma thermosetting sayansi malinga ndi momwe amachitira akamatenthetsa;

2. Malinga ndi mtundu wa zomwe zimachitika panthawi yophatikizira utomoni mu pulasitiki, utomoniwo ungagawidwe m'mapulasitiki apulasitiki ndi mapulasitiki oponderezedwa;

3. Malinga ndi dongosolo la utomoni wa macromolecule, mapulasitiki atha kugawidwa m'magulu awiri: mapuloteni amorphous ndi ma crystalline plastiki;

4. Malinga ndi magwiridwe antchito ndi kagwiritsidwe kake, mapulasitiki amatha kugawidwa m'mapulasitiki ambiri, mapulasitiki amisiri, ndi mapulasitiki apadera.

Pakati pawo, mapulasitiki opanga ntchito ndi omwe amagwiritsidwa ntchito kwambiri pamoyo wathu watsiku ndi tsiku. Mapulasitiki opanga zonse amatanthauza mapulasitiki okhala ndi voliyumu yayikulu yopanga, kupezeka kwakukulu, mtengo wotsika komanso oyenera kugwiritsira ntchito kwakukulu. Pulasitiki General-cholinga ndi wabwino akamaumba processability, ndipo akhoza kuumbidwa mu mankhwala zolinga zosiyanasiyana ndi njira zosiyanasiyana. Mapulasitiki omwe amapangira zinthu zambiri amaphatikizapo polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), acrylonitrile / butadiene / styrene (ABS).

Nthawi ino ndikulankhula makamaka za zinthu zazikulu komanso kagwiritsidwe ntchito ka polyethylene (PE). Polyethylene (PE) ili ndi zinthu zabwino kwambiri zogwiritsira ntchito komanso zogwiritsira ntchito, ndiyo mitundu yogwiritsidwa ntchito kwambiri pamatumba opanga, ndipo mphamvu zake zopanga zakhala pachikhalidwe choyamba pakati pa mitundu yonse ya pulasitiki. Mapuloteni a polyethylene amaphatikizira polyethylene yotsika kwambiri (LDPE), polyethylene yotsika kwambiri (LLDPE), komanso polyethylene yochuluka kwambiri (HDPE).

Polyethylene imagwiritsidwa ntchito kwambiri m'maiko osiyanasiyana, ndipo kanema ndiye wogwiritsa ntchito kwambiri. Imanyeketsa pafupifupi 77% ya polyethylene yotsika kwambiri ndi 18% ya polyethylene yotsika kwambiri. Kuphatikiza apo, zopangidwa ndi jakisoni, mawaya ndi zingwe, zopangira zopanda pake, ndi zina zambiri zimagwiritsa ntchito kapangidwe kake Kukula kwakukulu. Mwa ma resin asanu omwe cholinga chake chimakhala chachikulu, kumwa kwa PE kumakhala koyamba. Polyethylene imatha kuwumbidwa ndikupanga mabotolo osiyanasiyana, zitini, akasinja amafakitale, migolo ndi zotengera zina; jakisoni wopangidwa kuti apange miphika yosiyanasiyana, migolo, madengu, madengu, madengu ndi zotengera zina zatsiku ndi tsiku, maswidi a tsiku ndi tsiku ndi mipando, ndi zina zambiri; extrusion akamaumba popanga mitundu yonse ya mapaipi, zomangira, ulusi, monofilaments, ndi zina zambiri. Itha kugwiritsidwanso ntchito popanga waya ndi zida zokutira chingwe ndi mapepala opanga. Mwa zina zomwe zimagwiritsidwa ntchito, malo awiri ogwiritsira ntchito polyethylene ndi mapaipi ndi makanema. Ndikukula kwakumatauni, kanema waulimi komanso mafakitole osiyanasiyana azakudya, nsalu ndi mafakitale, chitukuko cha magawo awiriwa chachulukirachulukira.
