ʻO PBT ka pōkole o Polybutylene terephthalate. Hoʻokaʻawale ʻia ia i ka moʻo polyester. Aia ia me 1.4-Butylene glycol a me terephthalic acid (TPA) a i ʻole terephthalate (DMT). He waiu translucent i ka opaque, crystalline thermoplastic polyester resin i hana ʻia ma o ke kaʻina hana hui. Me ka PET, ua kapa ʻia ʻo ia ka polyester thermoplastic, a i ʻole polyester saturated.
Nā hiʻohiʻona o PBT Plastics
1. ʻO ka maʻalahi o ka plastic PBT he mea maikaʻi loa ia a he kūpaʻa loa hoʻi i ka hāʻule ʻana, a ʻoi aku ka ikaika o kona kūʻē ʻana.
2. ʻAʻole hiki ke puhi ʻia ka PBT e like me nā plastic plastic maʻamau. Eia kekahi, ʻoi aku ka kiʻekiʻe o kāna hana hoʻopau ponoʻī a me nā waiwai uila i loko o kēia plastic thermoplastic, no laila ke kumu kūʻai ma waena o nā plastics.
3. He haʻahaʻa loa ka hana ʻana o ka wai o ka PBT. Hoʻololi maʻalahi nā plastik maʻamau i ka wai me kahi mahana kiʻekiʻe. ʻAʻohe pilikia o PBT. Hiki ke hoʻohana no ka manawa lōʻihi a mālama i ka hana maikaʻi loa.
4. ʻO kaʻili o ka PBT he maʻalahi loa a he liʻiliʻi ka'āpana friction, kahi e maʻalahi ai ka hoʻohana. No ka li'ili'i o kona ho'opa'apa'a, no laila, ho'ohana pinepine 'ia i nā manawa he nui ka pohō.
5. He paʻa paʻa loa ka PBT plastic i ka wā i hoʻokumu ʻia ai, a ʻoi aku ka nui o ka pololei o ke ana, no laila he mea kiʻekiʻe loa. ʻOiai i loko o nā kemika lōʻihi, hiki iā ia ke mālama maikaʻi i kona kūlana mua, koe wale nō kekahi mau mea e like me nā waikawa ikaika a me nā kumu ikaika.
6. Nui nā plastics i hoʻoikaika ʻia i ka maikaʻi, akā ʻaʻole nā mea PBT. ʻOi aku ka maikaʻi o kāna mau kahe, a ʻoi aku ka maikaʻi o kāna mau hana ma hope o ka hoʻoheheʻe ʻana. No ka mea, hoʻohana ʻo ia i ka ʻenehana fusion polymer, hoʻopiha ia i kekahi mau waiwai alloy e pono ai ka polymer.
Hoʻohana nui o PBT
1. Ma muli o ka maikaʻi o kona kino kino a me ka kemika, hoʻohana mau ʻia ʻo PBT ma ke ʻano he mea extrusion no ka uhi lua o nā fiber optical ma waho o ke kelepona fiber optical.
2. Nā polokalamu uila a me ka uila: nā mea hoʻohui, nā ʻāpana hoʻololi, nā mea pono hale a i ʻole nā mea hoʻohui (ke kū ʻana i ka wela, ka pale ʻana o ka lapalapa, ka hoʻoheheʻe uila, ka hana maʻalahi a me ka hana ʻana).
3. Nā kahua noi o nā ʻāpana kaʻa: nā ʻāpana o loko e like me nā wiper brackets, control system valves, etc.; nā ʻāpana uila a me nā ʻāpana uila e like me nā paipu wili wili kaʻa a me nā mea hoʻopili uila pili.
4. Mahele noi lako mīkini maʻamau: ka uhi kamepiula, ka uhi kukui mercury, ka uhi hao uila, nā ʻāpana mīkini hoʻomoʻa a me ka nui o nā mīkini, nā kāmela, nā pihi, nā pūpū wati uila, nā wili uila a me nā pūpū mechanical ʻē aʻe.
