Te mārama ki ngā mātāpono o te tukanga hanga pupuhi extrusion, ngā painga, me ngā āhuatanga awe

Ko te whakapūtanga pupuhi whakaputa (EBM) he tukanga e whakamahia ana hei hanga pounamu kirihou tuwhera, ipu, me ētahi atu āhua mā te whakamahi i te polyethylene matotoru-teitei (HDPE) me te polypropylene (PP) rānei. Ko te tikanga he whakamahana i ngā pirepire kirihou, i ngā maramara rānei kia rewa, kātahi ka whakaputa mā roto i te mata hei hanga i tētahi parison kua oti te hanga. Kātahi ka pupuhihia tēnei parison ki te hau, ki te hauota rānei, ka whakamataohia, ka tukuna atu i te pokepokea ai.

Ko ngā painga o te EBM ko tōna kaha ki te whakaputa i ngā āhua uaua, ngā tere whakaputa teitei, me te kaha miihini pai. He iti ake te utu ki te whakataurite ki ētahi atu tukanga hanga. Heoi, kāore te EBM e pai mō ngā rauemi katoa, ā, me whai taputapu me ngā taputapu motuhake pea.

Ko ētahi o ngā mea e awe ana i te EBM ko te whiriwhiri rauemi, te hoahoa mīhini, ngā āhuatanga tukanga, me te hoahoa pokepokea ai. He mea nui te whiriwhiri rauemi, nā te mea he rerekē ngā ira rewa, ngā matotoru, me ngā āhuatanga wera o ētahi rauemi. Me whakarite e te hoahoa mīhini te whakaranu tika o ngā rauemi, te whakamahana, me te whakamatao kia tutuki ai te putanga e hiahiatia ana. Ka pāngia te kounga o te hua whakamutunga e ngā āhuatanga tukanga pēnei i te pēhanga werohanga, te tere o te tīwiri, me te wā whakamatao. He mea nui te hoahoa pokepokea ai hei whakarite i te kounga pai o te hua, te ngāwari o te horoi, me te pono mō te wā roa. Hei whakarāpopototanga, he tukanga pokepokea ai maha ngā mahi, ā, he iti te utu e taea ai te whakaputa i ngā āhua uaua me ngā tere whakaputa teitei. Heoi, me tino whiriwhiri rauemi, hoahoa mīhini, me ngā āhuatanga tukanga kia pai ai te kounga o te hua whakamutunga.
