Kusanthula kwa zinthu zomwe zimafunikira chisamaliro pakuwongolera kuwombera

 

Extrusion, yomwe imadziwikanso kuti extrusion blow molding, ndi njira yogwiritsira ntchito extruder (extruder) kuti motsatizana adutse utomoni wotentha kudzera mukufa kuti atulutse chinthu cha mawonekedwe omwe mukufuna.Extrusion imagwiritsidwanso ntchito popanga ma thermosets ndipo imatha kugwiritsidwa ntchito popanga mapulasitiki okhala ndi thovu.

Ubwino wa extrusion kuwomba akamaumba ndi kuti akhoza extrude mankhwala akalumikidzidwa zosiyanasiyana, ndi mkulu kupanga dzuwa, ndipo akhoza yodzichitira ndi mosalekeza kupanga;kuipa kwake ndikuti mapulasitiki a thermosetting sangathe kukonzedwa ndi njira iyi, ndipo kukula kwake kumakonda chizolowezi.

Kuumba jekeseni kumadziwikanso kuti jekeseni kuwombera.Kumangira jekeseni ndi njira yogwiritsira ntchito makina opangira jakisoni (kapena makina ojambulira) jekeseni wosungunula wa thermoplastic mu nkhungu yothamanga kwambiri, kenako kuziziritsa ndi kulimba kuti mupeze mankhwala.Jekeseni akamaumba angagwiritsidwenso ntchito akamaumba thermosets ndi thovu.

Ubwino wa jekeseni wopangira jekeseni ndikuti liwiro la kupanga limakhala lofulumira, kugwira ntchito bwino ndipamwamba, ntchitoyo imatha kukhala yokha, ndipo imatha kupanga magawo omwe ali ndi mawonekedwe ovuta, omwe ali oyenera kwambiri kupanga zambiri.Choyipa chake ndi chakuti mtengo wa zida ndi nkhungu ndi wokwera, ndipo kutsekedwa kwa makina opangira jekeseni ndikovuta.

Kumangirira mphutsi kumatchedwanso kuumba kopanda kanthu kapena kuumba mozungulira.Kuwomba ndi njira yowonjezerera parison yotentha yotsekedwa mu nkhungu kuti ikhale yopanda kanthu pogwiritsa ntchito mpweya woponderezedwa.Kuwomba kuwombera kumaphatikizapo njira ziwiri zowuzira filimu ndi kuwomba zinthu zopanda kanthu.Mafilimu, mabotolo osiyanasiyana, migolo, mitsuko ndi zoseweretsa za ana zitha kupangidwa ndi kuwomba.

Mwachitsanzo, chifukwa chiyani botolo limangogwiritsa ntchito kuwombera, koma lingagwiritse ntchito jekeseni?Chifukwa chake ndikuti danga lamkati la botolo ndi lalikulu ndipo pakamwa pa botolo ndi laling'ono, kotero kuti jekeseni wopangira jekeseni sangathe kuchotsedwa.Choncho, kuwomba akamaumba opanga masangweji pulasitiki yofewa kusungunula pakati nkhungu ndi kuwomba kuti amamatire ku khoma lamkati la nkhungu popanda ntchito pachimake.
