10 ngā kōrero mō ngā mīhini hanga pereki kirihou#nailoni kua whakarerekētia

He tino pai te mahi a te nairona, nō reira he whānuitia te whakamahinga i roto i ngā motuka, i ngā taputapu hiko me ngā taputapu hiko, i ngā hanganga mīhini, i ngā taputapu hākinakina, i ngā kakahu, me ētahi atu. Heoi, nā te whakaitiiti i ngā motuka, te mahi teitei o ngā taputapu hiko me ngā taputapu hiko, me te mama o ngā taputapu mīhini, ka piki haere te tono me ngā whakaritenga mahi mō te nairona. Nō reira, he mea tino nui te whakarerekētanga o te nairona.

Ngā whakatūpato mō te whakarerekētanga nairona

1. Tautuhinga pāmahana o te oko

(1) Nā te mea he pūhui tioata te nairona, he mārama te ira rewa. Ko te pāmahana o te nairona i roto i te oko i te wā e werohia ana, e whakawhirinaki ana ki te mahi a te kapia, te mīhini me te āhua o te hua.

(2) Ki te tino teitei rawa te pāmahana o te rauemi, ka ngāwari te huri i te tae, te pakarukaru me te whakararuraru i ngā miro hiriwa. kirihou ngā wāhanga, ā, ki te tino iti te pāmahana o te rauemi, ka tino mārō te rauemi, ka kino hoki te pokepokea ai me te tīwiri.

(3) Ko te tikanga, ko te pāmahana rewa iti rawa o PA6 he 220℃, ā, ko te PA66 he 250℃. Nā te ngoikore o te pumau wera o te nairona, kāore e pai kia noho roa ki roto i te oko i te pāmahana teitei hei karo i te hurihanga me te kōwhai o te rauemi. I taua wā anō, nā te mea he pai te rere o te nairona, ka tere te rere i muri i te neke ake o te pāmahana i tōna ira rewa.

2. Tautuhinga pāmahana pokepokea ai

(1) He pānga tō te pāmahana pokepokea ki te matotoru o te kiri me te mimiti o te pokepokea. Kei waenganui i te 80 ki te 120°C te pāmahana o te pokepokea.
Kōwhiria te pāmahana pokepokea teitei, te tioata teitei, te ātete kakahu nui ake, te pakeke, te ngāwari o te whakapūmau, te mimiti wai iti iho, te whakaiti i te whakaiti o te hua, he pai mō ngā hua matotoru; whiriwhiria te pāmahana pokepokea iti, te tioata iti, te pakari pai, te roa teitei ake, te whakaiti i te tere whakaiti, he pai mō ngā hua angiangi me te mārama pai.

(2) Mena he nui ake te matotoru o te pakitara i te 3mm, me whakamahi he pokepokea pāmahana iti i te 20~40℃. Mō ngā rauemi whakakaha karāhe, me nui ake te pāmahana o te pokepokea i te 80°C.

(3) Te whakahaere pāmahana o ngā pokepokea ai he angiangi te pakitara o te hua, he uaua ki te hanga, he nui rānei te tioata e hiahiatia ana. Mena he iti te ngāwari o te hua, ka whakamahia te whakahaere pāmahana wai matao.

3. Te matotoru o te pakitara o te hua

Ko te ōwehenga roa rere o te nairona he 150 ki te 200, ā, ko te matotoru o te pakitara o te hua kāore i raro iho i te 0.8mm, ko te tikanga 1 ki te 3.2mm. Heoi anō, ko te mimiti o te hua e pā ana ki te matotoru o te pakitara o te hua. Ka matotoru ake te matotoru o te pakitara, ka nui ake te mimiti.

4. Ngenge

Ko te nui o te waipuke o te kapia nairona he tata ki te 0.03mm, nō reira me whakahaere te mokowā hau i raro i te 0.025.

5. Ngā kaiārahi me ngā kūaha

Kaua te whānui o te kōhao o te keti e iti iho i te 0.5t (ko te matotoru o te wāhanga kirihou te t). Mō ngā keti ruku, me 0.75mm te whānui iti rawa o te keti.

6. Awhe whakakī muka karāhe

I te wā e hangaia ana te nairona, mā te whakaheke i te pāmahana pokepokea ai, te whakanui ake i te pēhanga werohanga, me te whakaheke i te pāmahana rauemi ka whakaiti i te tere mimiti o te nairona ki tētahi taumata, ka ngāwari ake te hua ki te whakarerekē i te āhua nā te pikinga o te ahotea o roto. Hei tauira, ko te tere mimiti o te PA66 he 1.5% ki te 2%, ā, ko te tere mimiti o te PA6 he 1% ki te 1.5%. I muri i te tāpiri i ngā tāpiringa muka karāhe, ka taea te whakaiti i te tere mimiti ki te 0.3%.

E whakaatu ana ngā wheako mahi, ko te nui ake o te muka karāhe e tāpirihia ana, ka iti ake te mimiti o te kapia nairona. Heoi, ki te nui rawa te muka karāhe ka tāpirihia, ka mānu ngā muka ki runga i te mata, ā, ka ngoikore te hototahitanga. I te nuinga o te wā, he pai te pānga o te tāpiri i te 30%.

7. Te whakamahi rauemi hangarua

He pai ake kia kaua e neke atu i te toru ngā wā hei karo i te pirau o te hua, i te hekenga ohorere rānei o ngā āhuatanga ā-tinana me ā-mīhini. Me whakahaere te nui o te paninga i raro i te 25%. Mā te paninga nui rawa ka rerekē haere ngā āhuatanga o te tukanga. Me whakamaroke te ranunga o ngā rauemi hangarua me ngā rauemi hou.

8. Nga tohutohu ahuru

I te tīmatanga o te kapia nairona, me tahuri tuatahi koe i te pāmahana o te pūwero, kātahi ka whakamahana i te oko. Ina āraia te pūwero, kaua e anga atu ki te kōhao o te pūwero kia kore ai e puta ohorere te rewa i roto i te oko nā te nui o te pēhanga, ā, ka puta he tūponotanga.

9. Te whakamahinga o te kaihoko tuku

Mā te whakamahi i te iti o te matū tuku ka taea te whakapai ake me te whakakore i ngā hapa pēnei i ngā mirumiru. Ko te matū tuku mō ngā hua nairona ko te konutea stearate, te hinu mā, me ētahi atu, ka taea rānei te whakaranu hei whakapiri ka whakamahia. Me iti te nui, me te ōrite hoki ina whakamahia hei karo i ngā hapa o te mata o te hua. Me whakawātea te tīwiri ina whakawetohia te mīhini kia kore ai e pakaru te tīwiri i te wā e whai ake nei.

10. Tukatuka-muri

(1) Me whakamahana te hua i muri i te hanganga.

Ngā tikanga e whakamahia whānuitia ana: I roto i ngā wai kohua teitei pērā i te hinu kohuke, te glycerin, me te paraffin wai, me 10 ki te 20°C te pāmahana whakamahana i te pāmahana whakamahinga. Ka rerekē te wā whakamahana i runga i te matotoru o te pakitara o te hua. Ko te matotoru he 10 ki te 15 meneti mēnā he iti iho i te 3 mm te matotoru, ā, ko te matotoru he 3 ki te 20 meneti. Ko te wā 6mm he 15 ki te 30 meneti. Me whakamatao mārire ngā hua whakamahana ki te pāmahana rūma hei ārai i te whakahokinga mai o te ahotea i roto i ngā hua i puta mai i te whakamatao ohorere. (2) Me whakahaere te maimoatanga whakahaere makuku i muri i te hanganga o te hua.

Ko te maimoatanga whakatikatika haumākū ka mahia i runga i ngā hua he nui te haumākū o te taiao. E rua ngā tikanga: ko tētahi ko te tikanga whakatikatika haumākū wai kohua; ko tētahi ko te tikanga whakatikatika haumākū wairewa pāhare pākawa waro (ko te ōwehenga o te pāhare pākawa waro ki te wai he 1.25:1, ko te ira koropupū he 121°C).

He māmā noa te tikanga whakahaere haumākū wai kohua, mena ka whakanohoia te hua ki tētahi taiao he haumākū 65% hei whakatutuki i te mimiti makuku taurite, engari he roa te wā e pau ana, ko te tikanga whakahaere haumākū wairewa pāhare pākawa waro me whakamahi i te waikawa acetic i te pāmahana tukatuka o te 80 ki te 100°C. Ko te tikanga whakahaere haumākū wairewa pāhare pākawa waro, ko te wā tukatuka e whakawhirinaki ana ki te matotoru o te pakitara o te hua, tata ki te 2 hāora ina 1.5 mm te matotoru o te pakitara, tata ki te 8 hāora ina 3 mm te matotoru o te pakitara, me te 16 ki te 18 hāora ina 6 mm te matotoru o te pakitara.
