Te whakarite rauemi mata me te maimoatanga i mua:
Ngā rauemi noa: Ko te uhi werohanga 28mm he mea hanga ki te PP (polypropylene) PE rānei (polyethylene). He pai te utu mō ēnei rauemi, ā, e tutuki ana i ngā paerewa pa ki te kai.
Te whakamaroke: Mena he nui te makuku o te rauemi (hei tauira, mō ētahi rauemi PE), me whakamaroke i te 55℃ mō te 2 hāora pea hei ārai i te hanganga o ngā mirumiru, ngā rārangi hiriwa rānei i muri i te whakakoi.
Ko te tukanga matua o te werohanga whakarewa:
Te Hanga me te Werohanga: Ka whakamahanahia ngā pire kirihou kua oti te tukatuka i roto i te oko mīhini werohanga (ko te pāmahana o te oko PP he tata ki te 180-280℃) ka kutikutihia ki te tīwiri (ko te tere hurihuri o te tīwiri kei waenga i te 1 ki te 150 rpm) kia rewa. Kātahi ka werohia tere ki roto i te kōhao pokepokea ai i te tere tae atu ki te 484 g/s.
Te pupuri i te pēhanga me te whakamatao: I muri i te whakakīnga o te kōhao i te rewa, me pupuri te pēhanga (ko te pēhanga he 60-80% o te pēhanga werohanga) hei whakakī anō i te rahinga o te rauemi e mimiti ana nā te whakamatao, kia kore ai e mimiti te hua. Muri iho, ka whakamataohia te pokepokea ai mā roto i ngā awa wai whakamatao i roto i te pokepokea ai (ko te wai mahana te tikanga). Me whakahaere te pāmahana o te pokepokea ai i te 60-90℃, he mea nui tēnei mō te kounga o te hua.
Te wetewete me te pana: Kia oti te whakamatao, ka whakatuwheratia te pokepokea ai. Ka panaia e te pūnaha pana o te mīhini werohanga (me te kaha pana tata ki te 70.6 kN) te tokotoko pana, te pereti pana rānei, ā, ka tangohia te taupoki pounamu kua whakarewaina mai i te pokepokea ai.
Te whakahaere i muri i te whakaputanga me te kounga:
Te Tukatuka-muri: Whai muri i te tangohanga, me kuti ngā kuaha o ngā taupoki pounamu, ā, me tukatuka anō hoki (pēnei i te whakamahana i ngā wāhanga rauemi PE, mā te rumaki i roto i te wai wera mō te 2-4 hāora).
Tirotiro Kounga: He taahiraa nui tēnei hei whakarite i te kounga o te hua. Me whakahaere ngā tirotiro maha, tae atu ki te rahi o te taupoki pounamu (hei tauira, me tutuki te rahi o te whakatuwheratanga o te pounamu o te taupoki 28mm ki ngā whakaritenga tuhi), te mahi hiri (pēnei i te kore turuturu i muri i te whakamātautau pēhanga ā-roto 0.2MPa mō te 30 meneti), me te kaha whakatuwheratanga o te mowhiti ārai-tahae (pēnei i te kaha o te 25-30N me whakamahi mō te whakatuwheratanga tuatahi).
?? Te tūranga nui o ngā pokepokea ai
Ko ngā pokepokea ai te ngako o te pokepokea ai werohanga. Ka pā tika mai tō rātou hoahoa me te hanga ki te kounga o ngā taupoki me te whai huatanga o te whakaputanga.
Te maha me te whakatakotoranga o ngā kōhao: Hei whakarei ake i te whai huatanga, he mea noa te whakamahi i tētahi hoahoa maha-kōhao (pēnei i te kōhao kotahi e rua ngā wahi, te kōhao kotahi e whā ngā wahi, neke atu rānei). Nā te iti o te rahi, he tino pai ngā taupoki pounamu 28mm mō te whakatakotoranga maha-kōhao.
Pūnaha ringihanga: Ko ngā momo kēti noa ko:
Pūwāhi kuaha: He pai mō ngā taupoki he āhua teitei. Ka taea te wehe aunoa, engari he uaua ake te hanganga o te pokepokea ai (me whai pokepokea ai he pereti-toru).
Kūaha hurihuri: Ka taea e ia te tapahi aunoa i te kūaha ina whakatuwheratia te pokepokea ai, ā, he mea noa te whiriwhiri.
Pūnaha oma wera: He whānuitia te whakamahinga i roto i te hanga tere-teitei, ka taea te whakaiti i te aukati o te oma, te whakanui ake i te tere whakamahinga rauemi, me te whakapoto i te huringa hanga (ka taea te tautoko i ngā huringa hanga tere kia poto noa iho i te <2 hēkona).
Pūnaha whakamatao: He mea nui tētahi ara iahiko whakamatao whai hua (pēnei i te pūnaha whakamatao takai-a tawhio noa) hei whakapai ake i te whai huatanga o te whakaputa me te ōritetanga o te hua.
Te wetewete me te tukatuka miro: Mō ngā taupoki pounamu he miro, hei tāpiri atu ki te wetewete ā-kaha (e pā ana ki ngā rauemi ngohengohe pēnei i te PP) me te pana matua reti (e whakamahia ana mō te whakahaere i ngā kōhao taha, i ngā poka taha rānei), ka taea hoki te whakamahi i tētahi tikanga pana tīwiri (mā te akiaki i te matua kia huri mā roto i ngā whata taputapu, i ngā tikanga rānei e peia ana e te motuka, kia tutuki ai te wetewete miro).
