Mō te tuku miihini ngāwari, ko te iti o te mahi koretake e pau ana i roto i te tukanga tuku hiko, ko te pai ake o te pānga penapena hiko. Mō te tukanga tuku hiko o te whitiki papatahi noa, ko te taumaha o te tinana whitiki, te horahanga kua takaihia i roto i te diameter o te wira me te kaha toronga pumau e whakatau ana i te whakapaunga hiko o te tinana whitiki i te wā e mahi ana. Nō reira, ko te whiriwhiri me te whirihoranga o te whitiki tuku i roto i ngā taputapu he mea nui hei whakapai ake i te penapena hiko, ā, ko te whitiki tuku me te roa pumau, te tinana whitiki ngawari me te waku mata ngawari te whiringa pai rawa atu mō ngā kaihoko. Ka whakaoti pai te whitiki taraiwa polyester a Annilte i ngā raruraru o runga ake nei.
1. Polyester me ngā āhuatanga penapena pūngao
a) He kaha kume teitei, he kume pumau.
I te nuinga o te wā, ki te whakaritea ki te papa, ko te kaha totoro pumau 1% o te whitiki polyester he 30% ki te 50% teitei ake, ko te tikanga kāore te whitiki e hiahia ki te whakarerekē i te kukū i muri i te whakarerekētanga o te kaha kukū. Hei tāpiri, he maeneene te mahi, he paku kukū, ā, kāore e ngawari te ngaro o te tere, kia iti ake ai te kawenga o te kawe, kia penapena ai i te whakapaunga hiko.
b) He mama ngā whitiki
Ko te paparanga kaha o te whitiki polyester he hanganga motuhake i hangaia ki te papanga polyester kaha-teitei, he iti-toronga, ina tukuna te mana kotahi, ka taea e koe te whiriwhiri i te whitiki papatahi angiangi, kia whakaitihia ai te wā o te inertia me te kaha centrifugal o te whitiki papatahi, kia whakaitihia ai tana ake whakapaunga pūngao me te penapena i te whakapaunga hiko.
c) He ngāwari pai
Nā te ngohengohe o te tinana o te whitiki polyester, he pai te takai o te tinana whitiki me te wira whitiki, ka whakaitihia te ahotea piko, ka whakapai ake i te pai o te tuku, ā, ka iti ake te penapena hiko.
d) He tere te hononga, ā, he pai hoki mō te taiao
Ka whakamahia e te hononga te here niho rewa wera o te elastomer thermoplastic tinana, kāore he piripiri e whakamahia ana, ā, kāore e herea te ahunga o te mahi, kia penapenahia ai te wā tāutanga me te whakaiti i te parahanga taiao.
2. Pānga penapena hiko
E whakaatu ana te whakamātautau whakatairite mara he nui ake te tere penapena hiko toharite o te rīpene polyester i te 10% i tērā o te roopu turanga maramara ā-rohe me tāwāhi.
He tino nui te pānga penapena hiko o te whitiki polyester, mō te mīhini miro paninga, ka taea te tere penapena hiko ki te 20%, mō te mīhini miro takirua muka poto, ko te tere penapena hiko neke atu i te 15%, mō te mīhini miro 310 ngā wā, ko te tere penapena hiko he 10%. Nō reira, me tana mahi penapena hiko tino pai, kua whakamahia whānuitia te whitiki polyester hei whitiki tarakona me te whitiki mana o ngā taputapu tere-tere hou pēnei i te mīhini miro hipoki, te mīhini miro roa rawa, te mīhini miro hurihuri me te mīhini miro takirua.
3. Te whakataurite i te mahi hanganga
Ko te whitiki polyester he mea hanga ki te rapa carboxyl nitrile butadiene hangai motuhake hei rauemi matua mō te paparanga taraiwa me te waku, ā, he rite tonu te mahi ki te papa o te papa.
Ko te pepa elastomer polymer thermoplastic te mea e whakamahia ana hei paparanga whakawhiti hiato. I muri i te maroke, ka rewahia ngā matūriki polymer thermoplastic ka tukuna ki waho e te extruder hei hanga i te pepa he matotoru ōrite me te whānui o te 1200mm. Ā, i runga i te matotoru rerekē o te tinana whitiki, he rerekē te matotoru o ngā hua pepa 0.3 ~ 1.2mm. He āhuatanga o te rauemi ko te ngāwari pai, te ātete ki te hinu, te ātete ki te pāmahana, te ātete ki te ngenge, te ngāwari, te iti o te taumaha motuhake me te mama, ā, he pai ngā āhuatanga here me te paparanga kaha me te rapa.
