1. Njira yopangira jekeseni ndikuwomba kuwombera ndi yosiyana.Kuwomba ndi jekeseni + kuwomba;jekeseni akamaumba ndi jekeseni + kuthamanga;Kuwomba kuyenera kukhala ndi mutu wosiyidwa ndi chitoliro chowomba, ndipo jekeseni iyenera kukhala ndi gawo la Chipata
2. Nthawi zambiri, jekeseni akamaumba ndi olimba pachimake thupi, nkhonya akamaumba ndi dzenje pachimake thupi, ndipo maonekedwe nkhonya akamaumba ndi wosafanana.Kuwomba kowomba kumakhala ndi doko lowombera.
3. jekeseni akamaumba, ndiye thermoplastic jekeseni akamaumba, mmene zinthu pulasitiki amasungunuka kenako jekeseni mu filimu patsekeke.Pulasitiki yosungunukayo ikalowa m’chikombole, imazirala n’kukhala ngati kabowo.Zomwe zimapangidwira nthawi zambiri zimakhala zomaliza ndipo palibe kukonzanso kwina komwe kumafunikira zida zisanachitike kapena kugwiritsidwa ntchito ngati chomaliza.Zambiri, monga mabwana, nthiti, ndi ulusi, zimatha kupangidwa popanga jekeseni imodzi.Makina omangira jakisoni ali ndi zinthu ziwiri zofunika: jakisoni yemwe amasungunula ndikudyetsa pulasitiki mu nkhungu, ndi chipangizo chomangira.Zotsatira za chida cha nkhungu ndi:
1. Nkhungu imatsekedwa pansi pa chikhalidwe cha kulandira jekeseni ya jekeseni.
2. Chotsani mankhwala muzitsulo za jekeseni kuti musungunuke pulasitiki musanalowe mu nkhungu, ndiyeno yesetsani kuthamanga ndi kuthamanga kuti mulowetse kusungunuka mu nkhungu.Pali mitundu iwiri ya zida za jakisoni zomwe zimagwiritsidwa ntchito masiku ano: screw pre-plasticizer kapena zida ziwiri, ndi screw reciprocating.Ma screw pre-plasticizers amagwiritsa ntchito screw pre-plasticizing screw (gawo loyamba) kubaya pulasitiki yosungunuka mu ndodo ya jakisoni (gawo lachiwiri).Ubwino wa screw pre-plasticizer ndi mtundu wokhazikika wosungunuka, kuthamanga kwambiri komanso kuthamanga kwambiri, komanso kuwongolera voliyumu yolondola (pogwiritsa ntchito zida zamakina kumapeto onse a pistoni).
Zopindulitsa izi zimafunikira pazinthu zomveka bwino, zokhala ndi mipanda yopyapyala komanso mitengo yayikulu yopanga.Zoyipa zimaphatikizapo nthawi yosagwirizana yokhalamo (zomwe zimabweretsa kuwonongeka kwa zinthu), kukwera mtengo kwa zida ndi ndalama zosamalira.Zida zojambulira zomangira zomwe zimagwiritsidwa ntchito mowirikiza sizifuna pulawuni kuti isungunuke ndi kubaya pulasitiki.
Kupanga mphamvu:amatchedwanso dzenje kuwomba akamaumba, kuwomba akamaumba, mofulumira kukhala pulasitiki processing njira.The tubular pulasitiki parison wopezedwa extrusion kapena jekeseni akamaumba thermoplastic utomoni amaikidwa mu nkhungu kugawanika pamene ndi kutentha (kapena kutenthedwa ndi boma anafewetsa), ndi wothinikizidwa mpweya umalowetsedwa mu ndende atangotseka nkhungu kuwomba pulasitiki parison. .Imakulitsa ndikumamatira pafupi ndi khoma lamkati la nkhungu, ndipo pambuyo pozizira ndi kugwetsa, zinthu zosiyanasiyana zopanda kanthu zimapezeka.Kapangidwe ka filimu yowombedwa ndi yofanana kwambiri pakuwomba akamaumba opanda pake, koma sagwiritsa ntchito nkhungu.Kuchokera pamalingaliro aukadaulo waukadaulo wa pulasitiki, njira yopangira filimu yowombedwa nthawi zambiri imaphatikizidwa mu extrusion.Njira yowumba nkhonya idagwiritsidwa ntchito koyamba kupanga mbale zotsika kwambiri za polyethylene pa Nkhondo Yachiwiri Yapadziko Lonse.Chakumapeto kwa zaka za m'ma 1950, ndi kubadwa kwa polyethylene yochuluka kwambiri komanso kupanga makina opangira nkhonya, luso loumba nkhonya linagwiritsidwa ntchito kwambiri.Kuchuluka kwa zotengera zopanda kanthu kumatha kufika malita masauzande ambiri, ndipo kupanga kwina kwatengera makompyuta.Pulasitiki yoyenera kuumba nkhonya imaphatikizapo polyethylene, polyvinyl chloride, polypropylene, polyester, ndi zina zotero, ndipo zotengera zopanda kanthu zimagwiritsidwa ntchito kwambiri ngati zotengera zamakampani.
