Kuyerekeza ubwino ndi kuipa angapo yaikulu processing njira pulasitiki zopangira

Jekiseni Kumangira
Mfundo yopangira jekeseni ndikuwonjezera zinthu za granular kapena ufa mu hopper ya makina ojambulira.Zinthuzo zimatenthedwa ndikusungunuka ndipo zimakhala zogwira ntchito.Pansi pa kupititsa patsogolo wononga kapena pisitoni yamakina ojambulira, imalowa mu nkhungu kudzera pa nozzle ndi njira yoponyera nkhungu., Imaumitsidwa ndi kuumbika mu nkhungu.Zomwe zimakhudza mtundu wa jekeseni: kuthamanga kwa jakisoni, nthawi ya jekeseni, kutentha kwa jekeseni.

Mphamvu
1. Short akamaumba mkombero, mkulu kupanga dzuwa, ndi zochita zokha mosavuta.
2. Ziwalo zapulasitiki zokhala ndi mawonekedwe osokonekera, miyeso yolondola, ndi zoyika zachitsulo kapena zopanda zitsulo zimatha kupangidwa.
3. Ubwino wazinthu ndi wokhazikika.
4. Zizolowezi zambiri.

Zoipa
1. Mtengo wa zida zopangira jekeseni ndi wapamwamba.
2. Mapangidwe a nkhungu ya jakisoni ndi osokonekera.
3. Kupanga kwamtengo wapamwamba, kuzungulira kwautali kwanthawi yayitali, kosayenera kwa gulu limodzi ndi laling'ono kupanga magawo apulasitiki.

Gwiritsani ntchito
Pakati pazinthu zamafakitale, zinthu zopangidwa ndi jekeseni zikuphatikizapo: zinthu zakukhitchini (zinyalala, mbale, zidebe, miphika, tableware, ndi zotengera zosiyanasiyana), zipolopolo za zida zamagetsi (zowumitsira tsitsi, zotsukira, zosakaniza zakudya, etc.), zoseweretsa ndi masewera, magalimoto Zinthu zosiyanasiyana zamafakitale, magawo azinthu zina zambiri, etc.
Extrusion akamaumba
Extrusion akamaumba: amatchedwanso extrusion akamaumba, makamaka oyenera akamaumba thermoplastics, komanso oyenera akamaumba ena thermosetting ndi kulimbikitsa mapulasitiki ndi kuyenda bwino.Njira yowumba ndikugwiritsa ntchito wononga chozungulira kuti mutulutse zinthu zotenthetsera komanso zosungunuka za thermoplastic kuchokera pakufa ndi mawonekedwe ofunikira, kenako zimapangidwa ndi chipangizo choyezera, kenako ndikudutsa chozizira kuti chikhale cholimba komanso cholimba. kukhala mawonekedwe ofunikira apakati.mankhwala.

Makhalidwe a Njira
1. Mtengo wotsika wa zida;
2. ntchitoyo ndi yosavuta, ndondomekoyi ndi yosavuta kulamulira, ndipo n'zosavuta kumaliza motsatizana kupanga makina;
3. Kupanga kwakukulu;yunifolomu ndi zabwino mankhwala khalidwe;
4. Pambuyo posintha kufa kwa mutu wa makina, zopangira kapena zomaliza zomwe zili ndi mawonekedwe osiyanasiyana amatha kupangidwa.

Gwiritsani ntchito
Pankhani ya kukonzekera kwazinthu, kuumba kwa extrusion kumakhala ndi mphamvu yogwira ntchito.mankhwala Extruded monga mapaipi, mafilimu, ndodo, monofilaments, malamba lathyathyathya, maukonde, muli dzenje, mazenera, mafelemu zitseko, mbale, cladding chingwe, monofilaments ndi zinthu zina profiled.

Kuwomba Kuumba
Zinthu zosungunuka za thermoplastic zomwe zimatuluka kuchokera ku extruder zimakanikizidwa mu nkhungu, ndiyeno mpweya umawululidwa muzinthuzo.Zinthu zosungunuka zimakula pansi pa mphamvu ya mpweya ndikumamatira ku khoma la nkhungu.Kuziziritsa ndi kulimbitsa kumakhala njira ya mawonekedwe omwe amafunidwa.Kuwomba kuwombera kumagawidwa m'mitundu iwiri: kuwomba filimu ndi kuwomba kopanda kanthu.

Mafilimu akuwomba
Kuwomba filimu ndi njira yotulutsa pulasitiki yosungunuka kukhala chubu chopyapyala chozungulira kuchokera pampata wozungulira wa kufa kwa extruder, ndikuwomba mpweya woponderezedwa kulowa mkati mwa chubu chopyapyala kuchokera pakatikati pa dzenje lakufa kuti mufufuze chubu chopyapyala mpaka a diameter.Kanema wamkulu wa tubular (omwe amadziwika kuti bubble chubu) amakulungidwa pambuyo pozizira.

Kupanga mpweya wochepa:
Hollow blowing molding ndi njira yachiwiri yopangira yomwe imagwiritsa ntchito mphamvu ya gasi kuti iwonjezere parison ngati mphira yotsekedwa mu nkhungu kukhala chinthu chopanda kanthu.Ndi njira yopangira zinthu zapulasitiki zopanda kanthu.Malinga ndi njira zosiyanasiyana zopangira ma parison, kuumba kobowola kumaphatikizapo kuumba kwa ma extrusion blowing, jekeseni wowotchera, komanso kuwongola kwamphamvu.
(1) Extrusion nkhonya akamaumba: Extrusion kuwomba akamaumba ndi ntchito extruder extrude tubular parison, atseke mu nkhungu patsekeke ndi kusindikiza pansi pamene kuli kotentha, ndiyeno kuwomba wothinikizidwa mpweya kulowa mkati mkati chubu akusowekapo. kukwera kwa inflation .
(2) Kujambula jekeseni: Parishi yomwe imagwiritsidwa ntchito imapangidwa ndi jekeseni.Parison imasiyidwa pachimake cha nkhungu.Pambuyo potseka nkhungu ndi nkhungu yowomba, mpweya woponderezedwa umayambitsidwa kuchokera pachikombole chapakati kuti ufufuze parison, kuziziritsa, ndi kupanga mankhwala kuti apeze mankhwala.
(3) Kuwomba nkhonya: Ikani parishi yomwe yatenthedwa mpaka kutentha kotambasula mu nkhungu yowomba, itambasulireni motalika ndi ndodo yotambasula, ndipo tambasulani ndikuyiyika ndi mpweya woponderezedwa munjira yodutsamo kuti mupeze Njira yofikira.

Mphamvu
Chogulitsacho chimakhala ndi makulidwe a khoma lofanana, kulemera kochepa, kuchepetsedwa kwapambuyo, ndi ngodya zazing'ono zowonongeka;ndizoyenera kupanga zinthu zazikulu zazing'ono zolondola.
gwiritsani ntchito:
Filimu kuwomba akamaumba zimagwiritsa ntchito kupanga nkhungu woonda pulasitiki;kuumba kobowola kumagwiritsidwa ntchito kwambiri popanga zinthu zapulasitiki zopanda kanthu (mabotolo, migolo yonyamula, zitini zopopera, akasinja amafuta, zitini, zoseweretsa, ndi zina).Kuti
