ʻO ka mea hoʻopaʻa calcium zinc kahi mea hoʻopaʻa wela ʻaʻohe ʻawahia i hana ʻia e kahi kaʻina hana hui kūikawā, i haku ʻia me nā paʻakai calcium, nā paʻakai zinc, nā lubricants, antioxidants, a pēlā aku. He mea polymer thermosensitive ia, e like me PVC CPVC, ʻO kekahi o nā mea hoʻohui koʻikoʻi no ka chloroprene rubber, i hoʻohana ʻia e pale a hoʻopaneʻe paha i kona hoʻohaʻahaʻa wela.
ʻAno hana o ka mea hoʻopaʻa calcium zinc
1. Hiki iā ia ke pani i nā hui hana i nā kaulahao polymer (e like me nā ʻātoma chlorine ma ke kūlana allyl ma PVC) e loaʻa ai nā polymers paʻa, a laila e hoʻopau ana i ke kumu o ka dehydrochlorination i nā mea polymer a me ka hōʻemi ʻana i ka hiki ke hoʻoulu i nā hopena dehydrochlorination.
2. Hiki ke hopu koke i ka hydrogen chloride i hoʻokaʻawale ʻia a kāohi i kona hopena autocatalytic
No laila he aha ke kuleana o ka polyethylene wax i nā mea hoʻopaʻa calcium zinc? I ka hana ʻana a me ka hana ʻana o nā huahana PVC palupalu a paʻakikī like ʻole, ʻaʻole wale nā mea hoʻopaʻa wela akā ʻo nā lubricants hoʻi e pono ai. He haʻahaʻa ka lubricity o ka calcium, no laila pono e hoʻohui ʻia nā mea hoʻohui wax e hoʻonui i ka hopena lubrication o ka huahana.
ʻO ka hoʻomaikaʻi ʻana i ka hana o ka calcium zinc stabilizer e ka oxidized polyethylene wax penei:
1. Loaʻa i nā molekole wax polyethylene oxidized nā hui hana e like me nā hui hydroxyl, hiki ke hoʻonui i ke kūpaʻa wela o nā mea hoʻopaʻa Ca/Zn
2. E hoʻomaikaʻi i ka launa pū me PVC, e hōʻemi i ka hau ʻana, a hoʻoikaika i ka hiki ke paʻi a me nā waiwai sila wela
3. Paipai i ka plasticization a hoʻomaikaʻi i ke kahe ʻana o nā mea PVC
4. ʻO ka hopena lubrication maikaʻi loa e hāʻawi i ka ʻōwili, extrusion, injection, a me nā lako hana hoʻoheheʻe me nā waiwai hoʻoheheʻe metala maikaʻi.
