HDPE jakisoni wopangira crate
HDPE jakisoni wopangira crate,
HDPE Kwa Crate, Kupanga jakisoni wa HDPE,
Bokosi lapulasitiki lopangidwa ndi jekeseni wa polyethylene (HDPE) wopangidwa ndi jekeseni woyamba.
Crate imapangidwa ndi zinthu zapadera za HDPE kuti ikhale yolimba kwambiri.Liwiro losungunuka la zinthu zapadera ndi 3.6-4.5 g / 10 mphindi, kupanikizika kumapitirira 25 Pa, mphamvu yowonjezereka ikupitirira 60% ndipo mphamvu yodutsa imadutsa 40 Pa. Kawirikawiri zinthu za HDPE zimakhala ndi nthambi zochepa, koma zatsopano zatsopano zomwe zimagwiritsidwa ntchito pamabokosi zimapatsa mphamvu zapakati pa ma intermolecular ndi mphamvu zolimba kuposa LDPE.Pamwamba pake ndizovuta komanso zowoneka bwino, ndipo zimatha kupirira kutentha kwakukulu (120 C / 248 F kwa kanthawi kochepa, 110 C / 230 F mosalekeza), kuti ifike pakufunika kolimba.Tiyenera kukumbukira kuti HDPE, mosiyana ndi polypropylene, silingathe kupirira kupanikizika kwakukulu.
Jekeseni Kumangira
Kumangira jekeseni ndi njira yopangira pulasitiki yomwe imaphatikizapo kubaya zida zapulasitiki zosungunuka m'chipinda chotsekedwa kapena nkhungu.Njirayi ili ndi njira zitatu zazikulu:
Kupera ndi kutentha pulasitiki mpaka itayenda pansi pa kupanikizika.
Kulowetsa pulasitiki mkati mwa nkhungu ndikulola kuti izizizire.
Kutsegula nkhungu kuti atulutse chidebe chapulasitiki.
A reciprocating wononga wononga mtundu extruder ntchito makamaka mu makampani kupanga pulasitiki osakaniza;pali kusakaniza mobwerezabwereza ndi kukankha wononga wononga extruder.Pamene pulasitiki (zopangira) zakonzeka kubayidwa, pamene wononga chimayenda, imakankhira pulasitiki kunja kwa extruder ndi kulowa mu nkhungu.
Kuti apange mawonekedwe ofunikira ndi kasitomala, pali nkhungu yopangidwa ndi zenizeni zomwe zimakhala ndi mawonekedwe enaake.Nthawi zambiri imakhala ndi magawo awiri kapena magawo awiri omwe ali ndi mawonekedwe ofanana.Mmodzi amatha kusuntha kapena amakhalabe pomwe mbali ina ya nkhungu imatha kusuntha.Pambuyo pa kuumba, theka lina likhoza kusuntha motero kumasula mankhwala ku nkhungu mu mawonekedwe osasunthika.Chikombolecho chimakhala ndi zotsegula zingapo kapena zingapo kapena njira.Izi zimagwiritsidwa ntchito polowetsa pulasitiki mu nkhungu, mpweya wotulutsa mpweya, ndi kulola pulasitiki kutuluka mu nkhungu.
Kumangirira jakisoni kumalepheretsa kupanga zikafika popanga zotengera zambali imodzi kapena mabokosi.Machubu, ndowe, makapu, zotengera zakudya, ndi mbale ndi zitsanzo.Payokha, kuumba jekeseni sikuli koyenera kupanga zinthu zotsekedwa, zopanda kanthu monga mabotolo apulasitiki ndichifukwa chake ndikoyenera kupanga makokosi otseguka.Kuti apange zinthuzi, gasi wa inert amagwiritsidwa ntchito.Izi zimagwiritsidwa ntchito chifukwa zimachotsa machitidwe omwe angabwere mu nkhungu pamene ndondomekoyo ikuyenda.Izi zimalowetsedwa mu nkhungu yodzazidwa pang'ono ndi pulasitiki yosungunuka.Izi zimakankhira pulasitiki pamwamba pa nkhungu kutulutsa gawo la dzenje.Njirayi imatchedwa jekeseni wothandizidwa ndi gasi.
Kugwiritsa ntchito
Gulu la jakisoni wa HDPE limagwiritsidwa ntchito popanga ziwiya zotha kugwiritsidwanso ntchito, monga zotengera moŵa, zomangira zakumwa, zomangira chakudya, masamba amasamba ndi mabwalo a dzira ndipo zitha kugwiritsidwanso ntchito popanga thireyi zapulasitiki, zotengera katundu, zida zapanyumba, kugwiritsa ntchito zinthu zatsiku ndi tsiku ndi zoonda- zotengera chakudya khoma.Itha kugwiritsidwanso ntchito popanga migolo yogwiritsira ntchito mafakitale, nkhokwe zotayira zinyalala ndi zoseweretsa.Kupyolera mu extrusion ndi psinjika akamaumba ndondomeko ndi jekeseni akamaumba, angagwiritsidwe ntchito kupanga zisoti za madzi oyeretsedwa, mchere madzi, chakumwa tiyi ndi madzi chakumwa mabotolo.
