He whānuitia te whakamahinga o ngā mīhini whakaputa tīwiri takirua mō te whakarerekētanga ā-tinana o ngā pūhui, ā, ka taea hoki te whakamahi mō te whakaputa i ngā hua kua whakarewaina. He pai ake ōna āhuatanga whāngai, ā, he pai ake ngā mahi whakaranu, whakaputa hau, me te horoi-ake i te mīhini whakaputa tīwiri kotahi. Mā te whakakotahitanga o ngā momo rerekē o ngā huānga tīwiri, ka taea te whakamahi i te mīhini whakaputa tīwiri takirua me te mahi whakaputa hau kua hangaia hei poraka hanga i roto i ngā āhuatanga e whai ake nei.
- Te whakaputanga o te masterbatch
Ko te ranunga o ngā matūriki kirihou me ngā tāpiringa te puranga matua. Kei roto i ngā tāpiringa ngā tae, ngā whakakī me ngā tāpiringa mahi. Ko te extruder takirua-wiri te taputapu matua o te raina whakaputa puranga matua, e whakamahia ana mō te whakakotahitanga, te horapa me te whakaranu i ngā tāpiringa i roto i te hanganga polymer.
- Te whakarerekētanga whakaranu
Ka whakarato i te mahi whakaranu pai rawa atu i waenga i te matihiko me ngā tāpiringa, ngā whakakī. Ko te muka karāhe te rauemi whakapakari tino nui, engari ka taea hoki te whakakotahi i ētahi atu muka me ngā kawe polymer. Mā te tāpiri muka me te whakakotahi ki ngā polymer, ka taea te whiwhi rauemi he kaha teitei me te ātete pānga teitei, ā, i te wa ano, ka taea te whakaiti i te taumaha me te utu.
- Pūwero
Nā te hononga tahi o ngā tīwiri e rua, ka whakahoutia tonutia te paparanga mata o te rauemi e te tukanga kutikuti i te tūranga hononga, ka whakapai ake hoki i te pānga o te putanga hau, kia pai ake ai te mahi a te mīhini whakaputa tīwiri-rua i te mīhini whakaputa tīwiri-kotahi kua pau. Te mahi a te putanga hau.
- Te whakaputa tika
Ka taea hoki e te mīhini whakaputa tīwiri-rua te whakakotahi i te whakaranu me te whakaputa whakarewa. Mā te whakamahi i tētahi pane motuhake me ngā taputapu e tika ana, ka taea te whakaputa hua kua oti i roto i te huarahi whai hua ake, pērā i ngā kiriata, ngā pereti, ngā paipa, me ērā atu. Ka taea e te whakaputa whakarewa tika te karo i ngā mahi o te whakamatao me te whakaputa pere me te whakamahana anō me te whakarewa, ā, ka iti ake te ahotea wera me te ahotea kutikuti o te rauemi. Ka taea e te tukanga katoa te penapena pūngao, ā, ka taea te whakarerekē ngāwari i te tauira.
