ʻO ka polyphenylene sulfide (PPS), me ka iwi kuamoʻo like ʻole, he polymer ʻāpana crystalline me ka hana hou ʻana i nā apo benzene i pani ʻia a me nā ʻātoma sulfur. ʻO ka PPS he plastic engineering kūikawā me ka hana kiʻekiʻe a me kahi helu heheʻe kiʻekiʻe a hiki i 280 ℃, hiki ke hoʻololi i ka metala. ʻO nā waiwai maikaʻi o ka resin PPS e hoʻokō i nā koi waiwai o ke koi ʻana i nā ʻāpana automotive.
He nui nā noi o ka PPS i ka ʻoihana kaʻa, a ke piʻi nei ke koi no ka PPS ma nā ʻāina hana kaʻa e like me India, Kina, a me Iapana e hoʻokō i nā koi no ka māmā a me ke kūpaʻa o nā kaʻa.
Loaʻa i ka resin PPS nā waiwai maikaʻi loa:
1. Ka hoʻopaʻa ʻana o ka lapalapa ʻana, UL94:V-0/5VA papa me ka hoʻohui ʻole ʻana i ka lapalapa ahi;
2. ʻO ke kūpaʻa kemika maikaʻi loa, hiki i ke kiʻekiʻe o ka hoʻoheheʻe ʻana i ka solvent-free dissolution ma lalo o 200 ℃, e like me ke kiʻekiʻe kūʻē kemika o PTFE;
3. 'O ke kūpa'a 'ano maika'i, ka ho'oha'aha'a ha'aha'a a me ka ho'onui laina laina; ma muli o ka haʻahaʻa haʻahaʻa wai, hiki ke mālama ʻia ke kūpaʻa dimensional maikaʻi loa i nā wahi kiʻekiʻe-humidity a me ka wela kiʻekiʻe.
4. ʻO nā waiwai mechanical koʻikoʻi, ka ikaika kiʻekiʻe a me ka rigidity kiʻekiʻe, hiki iā ia ke mālama i ke kūpaʻa luhi a me ke kūpaʻa kolo i nā ʻano like ʻole;
5. Kūleʻa wela maikaʻi, UL wela index (RTI): 200-220 ℃, HDT (heat distortion wela)> 260 ℃.
Hoʻohana ʻole ʻia ka PPS maʻemaʻe ma muli o kona palupalu. ʻO ka PPS i hoʻohana ʻia ka hapa nui o kāna ʻano i hoʻololi ʻia, i hoʻololi pinepine ʻia e ka hoʻohui ʻana i ka fiber aniani.Hōʻike ka papa ma lalo nei i nā noi kūpono o nā resins i hoʻololi ʻia PPS maʻamau i ke kahua kaʻa:
| Mea wehewehe | Nā mea nui | Nā noi |
| PPS+40%GF | 40% aniani fiber i hoʻoikaika ʻia, ikaika kiʻekiʻe, rigidity kiʻekiʻe, kūpaʻa wela kiʻekiʻe, ka aila a me ka pale kemika, ke kūpaʻa maikaʻi. | Pump impellers, valve housings and bushings, coil through, gearboxes, circuit breakers, lamp sockets, lamp reflector cups and brackets, junction boxes, automotive fuel systems, etc. |
| PPS+65%(GF+MF) | 65% aniani fiber/mineral i hoʻoikaika ʻia, kūlana kūpaʻa maikaʻi loa, kūpaʻa wela kiʻekiʻe, ʻoʻoleʻa kiʻekiʻe, hoʻopau ʻili kiʻekiʻe. | ʻO ka hui ʻana i nā mea hoʻohui valve, nā mea nānā wela kiʻekiʻe, nā hale pahū, nā hui kukui, etc. |
| PPS+30%CF | 30% carbon fiber i hoʻoikaika ʻia, kiʻekiʻe uila a me ka thermal conductivity, antistatic lōʻihi, ikaika kiʻekiʻe | Nā Puhi Pepa, Nā Lima Paʻa, Nā Pale Rotor Hoʻohālike Hoʻohālike, Nā ʻāpana Clutch, Bushings, etc. |
| PPS+30%GF+15%PTFE | 30% aniani fiber i hoʻoikaika ʻia, 15% PTFE lubricated, kiʻekiʻe thermal deformation paʻa, lapalapa ahi, kiʻekiʻe ikaika, haʻahaʻa kolo, hoʻomaikaʻi friction, maikaʻi loa pale pale. | ʻO nā injectors, manifolds, pumps, pistons, gears, V-ring gaskets, bearings, control discs, gears, impeller pumps, automotive electric gear parts, etc. |
| PPS hooluolu | ʻO ka hoʻoili wela, ka hoʻokaʻawale uila, ka pale ahi, UL94 V0, ikaika maikaʻi a paʻakikī. | ʻO nā mea wela, nā ʻāpana kaʻa, nā kumu LED, nā papa kaapuni wela, nā mea hoʻomaha, etc. |
SIKOPOLYMERS 'Nā māka nui o PPS a me kā lākou hōʻailona like a me kā lākou papa, e like me kēia:
