Chiyambi cha wopanga mabotolo a PET ku China

Polyester PET imagwiritsidwa ntchito kwambiri muMakina opangira mabotolo a PET, botolo la ziweto kupita ku makina a polyester ulusi ndi filimu ya polyester, zogawidwa mu ulusi wa polyester ndi ulusi wofunikira wa polyester, zomwe zimapangitsa pafupifupi 75% ya polyester yonse yopangidwa. Amagwiritsidwa ntchito kwambiri m'makampani opanga nsalu: makina opangira mabotolo a polyester PET, omwe ndi pafupifupi 20%, omwe amagwiritsidwa ntchito makamaka popangira chakudya ndi zakumwa; filimu ya polyester ndi pafupifupi 5%, yomwe imagwiritsidwa ntchito kwambiri popanga zinthu zakunja, yokhala ndi mphamvu yabwino yosindikizira.

Botolo la PET ndi chinthu chopangidwa ndi polyester chomwe chimateteza chilengedwe. Poyerekeza ndi galasi, chitsulo, pepala ndi zinthu zina zomangira pulasitiki, botolo la PET lili ndi ubwino wotetezeka, kuwonekera bwino, zinthu zopepuka, kunyamula mosavuta, kuteteza chilengedwe ndi zina zotero, kotero limagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana.
Mapepala a botolo la polyester nthawi zambiri amatanthauza kupanga polymerization kwa zinthu zopangira polyester zomwe nthawi zambiri zimakonzedwa kukhala tinthu ta pepala ta 452 mm. Njira yopangira polyester imaphatikizapo direct esterification (PTA) ndi transesterification (DMT). Njira yaukadaulo ya machitidwe akuluakulu a mankhwala mumakampani a PET am'nyumba ndi njira ya PTA, ndipo njira yopangira zinthu ziwiri yakhala yokhwima. Makampani opanga ma PET apamwamba a Chinese Wankai New Material, China Resources Materials ndi mabizinesi ena ndi a njira yopangira zinthu ziwiri za polyester + solid phase shrinkage ndi cohesion process (CP + SSP).

Malinga ndi ziwerengero, mu 2022, mphamvu yopangira pepala la botolo la polyester ku China ndi matani 12.99 miliyoni, ndi kukula kwa chaka ndi chaka kwa 3.59%. Mu 2022, mphamvu yopangira botolo la polyester ndi matani 450,000, pakati pawo mphamvu yatsopano yopangira ndi matani 600,000 a Chongqing Wankai. Pofika mu 2022, pali mabizinesi 16 a PET omwe ali ndi mabotolo ku China, omwe ali ndi mphamvu yonse yopangira matani 12.7 miliyoni pachaka. Pakati pawo, pali mabizinesi 5 omwe ali ndi mphamvu yopangira matani oposa 1 miliyoni, omwe ndi Wkai New Material, Hainan Yisheng,SANFAME, China Resources Materials ndi Jiangyin Chenggao (Jiangyin Chenggao matani 1.2 miliyoni makina a PET bottle flakes asinthidwa kupita ku China Resources chifukwa cha bankirapuse).

Otsatirawa ndi makampani angapo opanga mabotolo a PET omwe ayambitsidwa, osasankhidwa mwadongosolo lililonse.

1, WKAI (301216)

Kampani ya Wkai New Materials Co., Ltd., yomwe idakhazikitsidwa mu 2008, ndi kampani yotsogola pa kafukufuku ndi chitukuko, kupanga makina opangira mabotolo a PET komanso kugulitsa zinthu za polyester ku China. Zinthu zazikulu za kampaniyo zikuphatikizapo PET ya mabotolo ndi Daylight PET. Patatha zaka zoposa 10, yapanga mphamvu yopangira matani 2.4 miliyoni a zidutswa za mabotolo pachaka, zomwe zili pakati pa zapamwamba padziko lonse lapansi. Zogulitsa zathu zimagulitsidwa kumayiko ndi madera mazana ambiri padziko lonse lapansi, ndipo ndi kampani yoyimira "Yopangidwa ku China" mumakampani opanga mabotolo a PET.

Chongqing Wkai New Material Technology Co., Ltd., kampani yothandizidwa ndi Wkai New Material, idakhazikitsidwa mu 2018, yomwe ili ku Fuling, Chongqing, yokhala ndi makina opangira mabotolo a PET okwana matani 1.2 miliyoni komanso ukadaulo wa zida zomwe zikutsogolera mumakampaniwa.

2, Gulu la SANFAME

Jiangsu SANFAME Poly Material Co., Ltd. ndi kampani yotsogola pamakampani odulira ma polyester a m'mabotolo ku China. Pakali pano, kuchuluka kwa ma polyester a m'mabotolo kumaposa matani 2.2 miliyoni, ndipo kuchuluka kwa ma PTA kumafika matani pafupifupi 2.9 miliyoni.

Mndandanda wa SANFAME group polyester slices umagwiritsidwa ntchito kwambiri m'mabotolo a zakumwa, mabotolo amafuta odyetsedwa, zokometsera, mabotolo a mankhwala,Kutulutsa pepala la PETya mapepala opakira ndi zotengera zina. Chifukwa cha kugwiritsa ntchito njira yapadera yopangira ndi ukadaulo wopanga, mankhwalawa ali ndi magwiridwe antchito abwino kwambiri opangira makristalo, kutentha kochepa kokonza, komanso osiyanasiyana opangira. Kampaniyo imagwiritsa ntchito ukadaulo wapamwamba kwambiri padziko lonse wa American DuPont, Swiss Brown.
