Ko te mīhini miro he mīhini e hanga ana i te otinga pūmua e hanga ana i te muka, e rewa ana rānei mai i ngā miro. E ai ki ngā tikanga miro muka rerekē, e toru ngā momo mīhini miro: te mīhini miro mākū, te mīhini miro rewa, me te mīhini miro maroke.

Mīhini miro mākū
He pai mō te miro i te muka viscose, te muka acrylic, te nairona, me ētahi atu. Ko te āhuatanga matua ko te putanga mai o te otinga polymer mai i te spinneret ka whakapūpū ki roto i te muka hou i roto i te kaukau whakapūpū. He iti te tere o te miro, he maha ngā wā kei raro iho i te 100 m/min, ā, ka taea e te tere miro tere teitei te eke ki te 200 m/min. Ka wehea ngā mīhini miro mākū ki ngā muka poto me ngā muka roa.

①Mīhini miro muka poto: Ka whakaurua te rongoā miro mai i te paipa werohanga, ka inehia tika e te papu ine, ka tātarihia e te tātari ki roto i te mīhini hurihuri, kātahi ka tukuna mai i te kōhao mīhini hurihuri ki roto i te kaukau totohu. I muri i te totohu, ka kohia ngā muka e tipu ake ana mā roto i te godet. Ka horoia, ka totorohia rānei ngā paihere ki te wai.
Ko te āhuatanga o te mīhini miro muka poto he maha ngā kōhao i roto i te pereti miro, ko te nuinga he 3,000 ki te tekau mano ngā kōhao.

②Mīhini miro miro: He rerekē i te mīhini miro muka poto, ka tāpirihia te tikanga takai o te miro totoka.
Ka haere te miro mai i te kaukau totoka mā roto i te godet i muri i te horoinga, ā, ka tomo ki te tāke hurihuri tere-tere mā te awaawa waea ārahi tauutuutu. Ka kiia tēnei mīhini miro he mīhini miro tāke hurihuri;
Ki te takaihia te miro ki runga i te porowhita mā roto i te godet, ka kiia he mīhini miro porowhita; ki te mea he tukatuka muri i mua i te takai, ka kiia he mīhini miro haurua-tonu;
Mena ka oti tonu ngā mahi miro me te tukatuka i muri i te mīhini miro, ka kiia he mīhini miro tonu. Ko te nuinga o te wā ka whakamahia ngā mīhini miro tonu mō te hanga taura viscose. Ko ngā miro miro mō te miro miro he 150 ngā kōhao, iti iho rānei, ā, ko te maha o ngā kōhao mō te miro muka taura e tae atu ana ki te 3000 ngā kōhao.

Mīhini Hurihuri Rewa
Whakamahia ana i roto i ngā taputapu miro o te polyester, te nairona, me te polypropylene. Ko te āhuatanga ko te totoka o te awa angiangi o te rewa hei muka ina tūtaki ki te hau makariri, ā, ka pupuhihia te hau makariri ki te awa angiangi kia ōrite i muri i te haere i roto i te tātari tino whai hua, te takirere whakahaere, me te taputapu huri. He tere te miro, ko te tikanga he 600-1500 m/min. E rua hoki ngā momo mīhini miro rewa.

① Mīhini miro miro: Ka rewahia ngā maramara polymer i muri i te whakaurunga ki te mīhini whakaputa tīwiri mai i te hopper, ā, ka panaia e te tīwiri ka tukuna ki roto i te pouaka hurihuri mā te paipa. Ka inehia te rewa ka haria ki te mīhini hurihuri (pereti) e te papu hurihuri i roto i te pouaka, ā, ka tūtaki te awa angiangi o te rewa-whakaputa mai i te mīhini hurihuri ki te hau matao i roto i te matapihi hurihuri hei whakamatao me te totoka hei muka. Ka takaihia te tikanga takai ki runga i te bobine.
Ko te maha o ngā kōhao i roto i te miro miro he mea noa mai i ētahi kōhao ki ngā tekau kōhao. Ka taea te tae ki te 200 kōhao ina mirohia te taura, ā, kotahi anake te kōhao ina mirohia te hiraka parauri. I tēnei wā, ka whakamataohia te awa rewa, ka whakapakeketia hei hiraka mā te kaukau wai.
Ko te ia o ngā mīhini miro miro rewa i ngā tau 1970 he miro maha-pito, arā, kei ia tūranga miro he 2, 3, 4, 6, neke atu rānei ngā miro hei whakanui ake i te putanga o te mīhini; miro tere-rahi Mō te hiraka, ko te tere miro he 3500～4000 m/min, tae atu ki te 5000 m/min. Mō ngā kete nui, ko te rahinga o ia kete ka taea te tae ki te 10 kg ki ngā tekau kg; ko te miro tonu, te miro, me te totoro kei roto i te mīhini miro i te wā kotahi, ā, kei reira anō ngā tukanga miro, tuhi, me te whakakī kakano e oti ana i runga i te mīhini miro (e kiia nei ko te hanga BCF), kua whakamahia i roto i te hanga polypropylene me te nairona. He hanganga kiato tēnei mīhini, he iti te tapuwae, ā, he teitei te pai o te hanga. Haunga tēnā, kei te piki haere tonu te taumata o te aunoatanga o ngā mīhini miro.

②Mīhini miro muka poto: Ki te whakataurite ki te mīhini miro miro, ko tōna āhuatanga he miro nui me ngā kōhao maha, ko te maha o ngā kōhao he 400 ki te 1100, ā, kua whakawhanakehia hei mīhini miro porowhita me ngā kōhao maha tae atu ki te 4000; I roto i te kakau miro, ka whakamahia he pūnaha pupuhi hau whakamatao me te pupuhi mowhiti, te pupuhi mowhiti rānei me te pupuhi taha. Kāore he tikanga takai motuhake mō ia tūranga miro. I muri i te haerenga o ngā miro o ia tūranga mā te pereti ārahi, mā te rotor iti rānei, ka tōia te tō e te mīhini kukume. Ārahihia ki te wira whāngai waea, kātahi ka whakatakotoria te tō ki roto i te peere hiraka. Ka taea e te kaha hiraka mō ia oko te tae ki te 450-2000 kg. Ina hangaia e ngā wheketere muka hangai nui ngā muka poto, ka whakamahia he miro tika. Ka puta te mīhini miro ara-poto miro-rewa me te kauhanga kore-miro.

Mīhini miro maroke
Whakamahia i roto i te hanga miro kiriaku me te nairona. Ka tomo te miro miro ki te kauhanga mai i te ngongo werohanga mā te tātari, te papu ine, me te miro hurihuri. Ka tūtaki te maturuturunga wai kua hangaia ki te hau wera i roto i te kauhanga, ka mimiti te whakarewa, ka totoka te polymer hei muka i roto i te maturuturunga wai, kātahi ka takaihia te tō ki roto i tētahi rahinga. O ngā rōra. Ko te tere hurihuri maroke ko te 200-800 m/min. Hei whakatutuki i ngā hiahia o ngā tukanga hurihuri motuhake, i puta mai ngā mīhini hurihuri maroke-mākū i ngā tau 1970.

Pūrere whakarewa
1 Mahi-te whakarato rauemi totoka, te rewa polymer, me te whakaputa rewa tauanga.
2 E toru ngā wāhanga o te wāhanga whāngai tīwiri, te wāhanga kōpeketanga, me te wāhanga ine.
3 Ko te mātāpono mahi o te mīhini tango tīwiri ko te wehewehe i te tīwiri me te nekehanga o te rauemi i ia wāhi o te tīwiri.

● Rohe whāngai (rohe whakamaroke) tīwiri inerite.
● I te haurua tuatahi (rohe whakamatao), ka tukuna te wai whakamatao mā roto i te koiri koti, mā roto rānei i te uho o roto o te tīwiri, <100℃ hei ārai i te rewa wawe o te rauemi, me te aukati mowhiti hei tiaki i te pūnaha taraiwa tīwiri mai i te wera.
● Ka ārai te haurua tuarua (rohe whakamahana-mua) i ngā huringa ohorere o te pāmahana o te rauemi mai i te rohe whāngai ki te rohe pēhi.
● Rohe pēhi (rohe rewa) Ka whakarewahia e te tīwiri āta haere, ohorere rānei te rauemi (whakamahana, kutikuti) me te pēhi (ka iti haere te rahinga o te awaawa tīwiri); ka whakahokia te hau, te mamaoa wai rānei ki te rohe whāngai.
● Te horahanga ine (te horahanga whakaōrite) me ētahi atu tīwiri papaku.

Pūrere kawe rewa, tohatoha, hurihuri, me te tiaki wera

1 Ko te paipa tuku rewa mai i te mīhini whakaputa tīwiri tuke ki te pouaka miro (ka hono tetahi pito ki te putanga tīwiri, ā, ka hono tetahi pito ki te paipa tohatoha rewa o te mīhini miro) - he ranunga biphenyl-diphenyl ether ā-roto kua hipokina ki te whakamahana (whakamātao rewa).
2 Te tinana o te pouaka hurihuri, te paipa tohatoha rewa, te pouaka whakamahana tekau biphenyl, te papu hurihuri me tana taputapu tuku, me te huihuinga pane hurihuri.

● Te kaupapa o te paipa tohatoha rewa
● Kia rite te tawhiti o te rewa ki ia tūranga hurihuri. Ka noho te rewa ki roto i te paipa tohatoha mō te wā poto; ka iti ake te takai whakamuri.
● Te āhua o te paipa tohatoha rewa: momo peka me te momo porowhita.

3 Te whakamahana i te pouaka hurihuri (pouaka whakamahana biphenyl)
