Kāore he whanariki i roto i te ine taumaha ngota, kāore he kakara, he haumaru, he hoa taiao hoki, ā, kua whakamanahia e te FDA. He whānuitia te whakamahinga i roto i ngā momo kapia kiriaku, styrene, ABS, ACRMBS, styrene-acrylic latex, nitrile latex, butadiene latex pērā i te tauhohenga polymerization. He tino hoa taiao tēnei hei ine taumaha ngota ngota matomato, hei whakawhiti mekameka, hei whakamutu mekameka me hei whakarerekē polymer.
1. I roto i te tukanga whakaputa o te kapia kiriaku me te polymerization ester kiriaku, mā te tāpiri i tēnei hua ka taea te whakarerekē i te taumaha ngota o te kapia. He iti te taumaha ngota ngota o te kapia kiriaku, he rite te taumaha, he pai te whakataurite, he rite te matotoru, he kanapa te āhua, he mārama, he pai te ātete ki te huarere taiao.
2. I roto i te hanga i ngā pūmua pēnei i te nitrile latex, te butadiene styrene latex, me te styrene-acrylic latex, mā te tāpiri i tēnei hua ka iti te tohatoha o te taumaha ngota ngota o te hua kapia, ka pai te ōritetanga o te whakaōritenga, kia oti ai te whakaōritenga o te hua e ai ki ngā whakaritenga o te tukanga.
3. i roto i te whakaputanga o te tukatuka ACR āwhina ka taea te whakahaere pai i te matotoru o roto o te hua.
4. He polystyrene me te kapia AB he kaha te pānga, ā, he pai te ārai-pakaru me te mahi pāmahana iti.
5. Ko te polymer vinyl resin SAN (polymer vinyl) te mana whakahaere i te taumaha ngota me te ōritetanga
6. Ka whakaitihia e te pūmua EVA te hanganga kanohi ika me te kohu.
7. He whāiti te rahi o ngā matūriki polymer i puta mai i ngā EP, ā, he pai ngā āhuatanga o te mata. Mā te PEwax ka taea te hangarua i te EPS.
8. Ka whiwhi te kapia styrene kua whakarerekētia i te rere pai o te rewa me ngā hua kore kakara. 5. Vinylpolymer (vinylpolymer), te tauhohenga polymerization whakatārewatanga. @Ngā hua PE kua honoa hei aukati wera. 200 kg/pahu rino. 0.5-3% (mā te taumaha)
Haumaru
Me mātua whai i ngā mahi whakatūpato haumaru i te wā e whakamahi ana i ngā matū. Kei roto i ēnei ko ngā mahi kua whakamāramahia i roto i ngā ture hauora me te haumaru ā-Motu, ā-Rohe me ā-Rohe, te hauhautanga pai o te wāhi mahi, te tiaki kiri pai me te mau i ngā mōhiti tiaki. Kei roto i te Pepa Raraunga Haumaru mō te kapia kiriaku styrene ngā mōhiohio haumaru katoa.
Rokiroki
Tirohia te pukapuka "Te Whakahaere me te Rokiroki i ngā Mararatanga Polymer". Me whai i ngā mahi whakatūpato haumaru i te wā e whakahaere ana i ngā matū. Kei roto i ēnei ko ngā mahi kua whakaahuatia i roto i ngā ture hauora me te haumaru ā-Motu, ā-Rohe me ā-Rohe, te hauhautanga pai o te wāhi mahi, te tiaki kiri pai me te mau i ngā mōhiti tiaki. Kei roto i te Pepa Raraunga Haumaru mō te kapia styrene acrylic ngā mōhiohio haumaru katoa.
