Me pēhea te whakapai ake i te marara o ngā ārai mura

I te whānui o te whakamahinga o ngā rauemi polymer me ngā hua hiko kaihoko i roto i te oranga o ia rā, kei te piki haere hoki te maha o ngā ahi, ā, he nui ake te mataku ki te kino e pā mai ana. Kua piki haere te hiranga o te mahi ārai mura o ngā rauemi polymer, kia tutuki ai ngā whakaritenga ārai mura o ngā hua kirihou me te rapa, kia whakaitihia ai te parahanga puehu e puta mai ana i ngā ārai mura, ka puta mai te masterbatch ārai mura, ā, he mahi nui, he mea nui hoki tana mahi i roto i te hanga o ngā hua whakamutunga.

Ka hangaia te puranga matua ārai mura kia rite ki tētahi tauira whaitake, mā te whakakotahitanga waro o te ārai mura, te kaiwhakamarara hinu me te kaikawe, mā te whakamahine matotoru, te whakaranu, te ōritetanga, kātahi ka whakapūpū i te extrusion. I roto i tēnei, he tino nui te mahi a te kaiwhakamarara, mā te tāpiri i tētahi ōwehenga o te kaiwhakamarara ka tino pai ki te whakatairanga i te marara o te ārai mura, kia ngāwari ai te marara ōrite i roto i te tukanga, kia ārai i te kohikohinga o te ārai mura, kia pai ake ai te pānga marara, kia pai ake ai te pānga ārai mura o ngā ngota ārai mura, kia pai ake ai te whai huatanga ārai mura o te kirihou, ngā hua rapa, ka mate te ahi i te wā tōmua.

Heoi, i roto i te mahi, he maha ngā wāhanga kirihou me te rapa kei roto ngā wāhanga ātete-mura kāore e kaha ki te mahi i ō rātou āhuatanga ātete-mura nā te kore taurite o te marara o te ātete-mura i roto i te rauemi i roto i te ahi, ka hua ake he ahi nui ake me ngā mate kino.

Hei whakatairanga i te horapa ōrite o ngā aukati mura, te masterbatch aukati mura rānei i roto i te tukanga whakaputa hua, hei whakaiti i te putanga mai o te horapa kore taurite i puta mai i te pānga aukati mura kāore e taea te whakamahi pai, me ētahi atu, me te whakapai ake i te kounga o ngā hua aukati mura, kua whakawhanakehia e SILIKE he tāpiringa silicone kua whakarerekētia, ko te SILIMER hyperdispersant.

Ko te SILIMER he momo siloxane whakarerekē kua whakakotahihia ki te poraka-toru, he mea hanga mai i ngā polysiloxanes, ngā rōpū porowhita me ngā rōpū mekameka waro roa. Ka taea e ngā wāhanga mekameka polysiloxane te mahi i tētahi mahi wehewehe i waenga i ngā ngota aukati mura i raro i te kutikuti miihini, hei ārai i te whakakotahitanga tuarua o ngā ngota aukati mura; he hononga kei ngā wāhanga mekameka rōpū porowhita ki te aukati mura, hei mahi hononga; he tino pai te hototahitanga o ngā wāhanga mekameka waro roa ki te rauemi turanga.

He pai tēnei raupapa hua mō ngā kapia kirihou wera noa, TPE, TPU me ētahi atu elastomers kirihou wera, ā, ka taea te whakapai ake i te hototahitanga i waenga i ngā tae/paura whakakī/paura mahi me ngā pūnaha kapia, me te pupuri i te āhua marara o ngā paura kia pumau.

I te wa ano, ka taea hoki te whakaiti i te matotoru o te rewa, te whakaiti i te taipana o te extruder, te pēhanga extrusion, te whakapai ake i te mahi tukatuka o te rauemi, me te pai o te hinu tukatuka, me te i te wa ano ka taea te whakapai ake i te ahua o te mata o te rauemi, me te maeneene me te kore e pa ki nga ahuatanga miihini o te rauemi, ko te whakatairanga i te marara rite o nga waahanga aukati-mumura hei whakatairanga i te paanga aukati-mumura o te hua whakamutunga kia pai ai te mahi ki nga otinga kounga teitei.

Hei tāpiritanga, ehara i te mea he pai anake tēnei raupapa hua mō te masterbatch mura-ātete anake, engari mō te masterbatch tae, ngā rauemi kukū-mua kua marara kē rānei.
