Njira Zitatu Zopangira Ma Blow Molding

Mu njira yopangira botolo la zodzikongoletsera la pulasitikiMu zotengera, nthawi zambiri mumamva mawu aukadaulo monga extrusion blow molding (EBM), injection stretch blow molding (ISBM), ndi injection blow molding (IBM). Nkhaniyi ikufotokoza mwachidule kusiyana pakati pa njira zitatuzi ndi zinthu zokhudzana nazo kwa oyang'anira zinthu:

Kupangidwa kwa extrusion blow molding botolo la zodzikongoletsera la pulasitikindi njira yopangira zinthu zopanda kanthu zopangidwa ndi thermoplastic. Zinthu zodziwika bwino zopangira zinthu zophwanyika ndi mabotolo, mabaketi, zitini, mabokosi, ndi ziwiya zonse zopakira chakudya, zakumwa, zodzoladzola, mankhwala, ndi zofunikira za tsiku ndi tsiku. Ziwiya zazikulu zopangira zinthu zophwanyika nthawi zambiri zimagwiritsidwa ntchito popakira zinthu za mankhwala, mafuta odzola, ndi zinthu zambiri. Mtengo wokonza zinthu panthawiyi ndi wapakati, ndipo mtengo wa chinthu ndi wotsika. Zinthu zomwe zimagwiritsidwa ntchito nthawi zambiri zimagwiritsidwa ntchito popakira ziwiya za mankhwala, kupakikira ziwiya za ogula, ndi kupakikira ziwiya za mankhwala. Ndi zoyenera kupanga zinthu zazikulu zokha, zokhala ndi mawonekedwe abwino, makulidwe ofanana a khoma, komanso kukonza pamwamba koyenera kumaliza kosalala, kozizira, komanso kosalala.

Njira yopangira jakisoni wa blow blow botolo la zodzikongoletsera la pulasitikiChoyamba amaika pulasitiki wosungunuka mu nkhungu yopangira jekeseni kuti apange botolo lopanda kanthu. Botolo lopanda kanthu limapangidwa pa nkhungu lopanda kanthu lokhala ndi mabowo ang'onoang'ono m'mphepete mwake. Kenako, limasunthidwa ku nkhungu yopangira blow molding ikadali yotentha. Kenako, nkhunguyo imatsekedwa ndipo mpweya wopanikizika umalowetsedwa kudzera mu chitoliro cha ndodo yapakati kuti uphulitse botolo lopanda kanthu ndikupangitsa kuti ligwirizane ndi khoma la nkhunguyo. Pomaliza, pambuyo pogwira ndi kuziziritsa, mpweya wopanikizika umatulutsidwa ndipo nkhunguyo imatsegulidwa kuti ichotse gawo la pulasitiki. Ndi yoyenera kupanga zinthu zazikulu zokha, yokhala ndi mawonekedwe apamwamba, makulidwe ofanana a khoma, komanso kukonza pamwamba koyenera kumaliza kosalala, kozizira, komanso kokhala ndi mawonekedwe.

Kupaka jakisoni wa kulowetsedwa kwa chitsulo chotambasula botolo la zodzikongoletsera la pulasitiki, yomwe imadziwikanso kuti ISBM, choyamba imagwiritsa ntchito makina opangira jekeseni poika botolo lopanda kanthu, lomwe kenako limatambasulidwa motalikira kenako limadzazidwa ndi mpweya wopanikizika kuti litambasulidwe mopingasa, zomwe zimapangitsa kuti chinthucho chikhale ndi mawonekedwe ofanana ndi m'bowo la nkhungu. Malinga ndi njira yopangira chinthucho, chingagawidwe m'magulu awiri a ISBM ya sitepe imodzi ndi awiri a ISBM.

Kuwonjezera pa njira zitatu izi zodziwika bwino zopangira nkhonya botolo la zodzikongoletsera la pulasitikiZipangizo zomangira zotengera, palinso njira zopangira jekeseni, njira zomangira zopondereza, ndi njira zopangira vacuum. M'tsogolomu, tidzakupatsani mfundo zina zokhudzana ndi zinthu zomangira zomwe mungawerenge mukamaphunzira za zinthu zomangira zokongoletsa, komanso kuti tithandize kulankhulana bwino ndi makasitomala athu mukagula zinthu zomangira mtsogolo.
