Puhi:ʻO kahi mea hoʻololi PVC me ka hoʻolālā core-shell ——ACR, he hopena maikaʻi kēia mea hoʻololi i ka hoʻomaikaʻi ʻana i ka plasticization a me ka ikaika hopena o PVC.

ʻO nā mea hana kemika ka hā o nā mea hana hou o kēia wā ma hope o ke kila, ka lāʻau a me ka sima, ʻo ka hapa nui o nā paipu plastik, nā pani puka a me nā puka makani, ke kūkulu ʻana i nā mea wai ʻole, nā mea hoʻonaninani, a me nā mea ʻē aʻe. ʻO ka polyvinyl chloride (PVC).
Hoʻohana nui ʻia ʻo PVC ma ke ʻano he mea kūkulu hale a ua hoʻohana nui ʻia kāna mau kiʻi plastik i nā puka o loko a me waho a me nā puka makani o nā hale a me nā ʻoihana hoʻonaninani, me nā hiʻohiʻona maikaʻi loa e like me ka mālama ʻana i ka wela, ka hoʻopaʻa ʻana, ka mālama ʻana i ka ikehu, ka insulation leo a me ke kumu kūʻai maʻalahi, etc. hoʻolauna, ua hoʻomohala wikiwiki ʻia ka huahana.
Eia nō naʻe, loaʻa i nā ʻaoʻao PVC kekahi mau hemahema, e like me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa ikaika, a me nā pilikia hana.No laila, pono e hoʻomaikaʻi ʻia nā waiwai hopena a me nā waiwai plasticizing o PVC.ʻO ka hoʻohui ʻana i nā mea hoʻololi i ka PVC hiki ke hoʻomaikaʻi maikaʻi i kona ʻano paʻakikī, akā pono e loaʻa i nā mea hoʻololi kēia mau waiwai: ʻO ka mahana hoʻololi aniani haʻahaʻa;ʻāpana kūpono me ka resin PVC;pili i ka viscosity o PVC;ʻaʻohe hopena koʻikoʻi i ka ʻike a me nā mea mechanical o PVC;maikaʻi nā waiwai a me ka hoʻonui hoʻokuʻu poʻo maikaʻi.
ʻO nā mea hoʻololi hopena maʻamau o PVC he chlorinated polyethylene (CPE), polyacrylates (ACR), methyl methacrylate-butadiene-styrene terpolymer (MBS), acrylonitrile-butadiene-styrene copolymer (ABS), ethylene a vinyl acetate copolymer (EVA), ethylene propylene rubber. (EPR), etc.
Ua hoʻomohala a ua hana kā mākou hui i kahi hoʻololi hoʻololi PVC core-shell JCS-817.He hopena maikaʻi kēia mea hoʻololi i ka hoʻomaikaʻi ʻana i ka plasticization a me ka ikaika hopena o PVC.
2 Manaʻo ʻia ʻo ia
ʻO ka nui o ka mea hoʻololi JCS-817 he 6% no 100 mau ʻāpana kaumaha o ka resin PVC.
3 Hoʻohālikelike hoʻokolohua hana ma waena o nā mea hoʻololi like ʻole a me kēia mea hoʻololi JCS-817
1. E hoʻomākaukau i nā mea kumu hoʻāʻo PVC e like me ke ʻano ma ka Papa 1
Papa 1
| inoa | Nā ʻāpana ma ke kaupaona |
| 4201 | 7 |
| 660 | 2 |
| PV218 | 3 |
| AC-6A | 3 |
| Titanium Dioxide | 40 |
| PVC (S-1000) | 1000 |
| Mea hoʻopaʻa kino kino | 20 |
| Kāleka kalapona | 50 |
2. E ho'āʻo i ka hoʻohālikelike o ka ikaika hopena: E hoʻohui i nā mea i luna a hoʻohui i ka hui me 6% o ke kaumaha o PVC me nā mea hoʻololi PVC like ʻole.
Ua ana ʻia nā waiwai mechanical e ka wili lua-roller open mill, vulcanizer flat, hana laʻana, a me ka mīkini hoʻāʻo honua a me ka mea hōʻike i ka hopena beam maʻalahi e like me ka hōʻike ʻana ma ka Papa 2.
Papa 2
| 'ikamu | ʻano hoʻāʻo | Nā kūlana hoʻokolohua | Unite | Nā kuhikuhi kikoʻī (JCS-817 6phr) | Nā kuhikuhi kikoʻī (CPE 6 hola) | Nā kuhikuhi kikoʻī (Ka laʻana hoʻohālikelike ACR 6phr) |
| Ka hopena (23 ℃) | GB/T 1043 | 1A | KJ/mm2 | 9.6 | 8.4 | 9.0 |
| Ka hopena (-20 ℃) | GB/T 1043 | 1A | KJ/mm2 | 3.4 | 3.0 | ʻAʻohe |
Mai kaʻikepili ma ka Papa 2, hiki ke hoʻoholo i ka ikaika o ka hopena o JCS-817 ma PVC ma mua o ka CPE a me ACR.
3. E ho'āʻo i ka hoʻohālikelike ʻana i nā waiwai rheological: E hoʻohui i nā ʻano hana i luna a hoʻohui i 3% o ke kaumaha o ka PVC i ka hui me nā mea hoʻololi PVC like ʻole a laila hui.
Hōʻike ʻia nā waiwai plasticizing i ana ʻia e ka rheometer Harper ma ka Papa 3.
Papa 3
| ʻAʻole. | Ka manawa hoʻopalekana (S) | Kaumaha kaulike (M[Nm]) | ʻO ka māmā holo ʻana (rpm) | Ka wela hoao (℃) |
| JCS-817 | 55 | 15.2 | 40 | 185 |
| CPE | 70 | 10.3 | 40 | 185 |
| ACR | 80 | 19.5 | 40 | 185 |
Mai ka Papa 2, ua emi ka manawa plasticization o JCS-817 ma PVC ma mua o ka CPE a me ACR, ʻo ia hoʻi, JCS-817 e hopena i nā kūlana hana haʻahaʻa no PVC.
4 Ka hopena
ʻOi aku ka ikaika o ka hopena a me ka waiwai plasticizing o kēia huahana JCS-817 ma PVC ma mua o CPE a me ACR ma hope o ka hōʻoia hōʻoia.
