PBT ndiyo chidimbu chePolybutylene terephthalate. Iyo inoratidzirwa mu polyester series. Inoumbwa ne1.4-Butylene glycol uye terephthalic acid (TPA) kana terephthalate (DMT). Iyo ine mukaka inopenya kune opaque, crystalline thermoplastic polyester resin inogadzirwa kuburikidza nekugadzirisa maitiro. Pamwe chete nePET, iyo yakaunganidzwa inonzi inonzi thermoplastic polyester, kana yakazara polyester.
Zvimiro zvePBT Plastiki
1. Iko kushanduka kwePBT plastiki yakanaka kwazvo uye zvakare inopesana zvikuru nekudonha, uye brittle resistance yayo inenge yakasimba.
2. PBT haibatiki semapurasitiki akajairwa. Pamusoro pezvo, basa rayo rekudzima moto uye zvinhu zvemagetsi zvakakwira zvakanyanya mupurasitiki iyi yethermoplastic, saka mutengo unodhura pakati pemapurasitiki.
3. Kubata kwemvura kwePBT kwakaderera zvikuru. Mapurasitiki akajairwa ari nyore kuremara mumvura ine tembiricha yepamusoro. PBT haina dambudziko iri. Inogona kushandiswa kwenguva yakareba uye kuchengetedza kuita kwakanaka kwazvo.
4. Nzvimbo yePBT yakanyanyisa uye friction coefficient iduku, izvo zvinoita kuti zvive nyore kushandisa. Imhaka yekuti friction coefficient idiki, saka inowanzoshandiswa muzviitiko apo kurasikirwa kwekukwenya kwakakura.
5. PBT plastiki ine kugadzikana kwakasimba chero bedzi yakaumbwa, uye inonyanya kukoshesa kurongeka kwedimensional, saka ipurasitiki yepamusoro-soro. Kunyangwe mumakemikari enguva refu, inogona kuchengetedza mamiriro ayo epakutanga zvakanaka, kunze kwezvimwe zvinhu zvakadai seasidhi yakasimba uye mabhesi akasimba.
6. Mapurasitiki akawanda anosimbiswa unhu, asi PBT zvinhu hazvisi. Kuyerera kwayo midziyo yakanaka kwazvo, uye maitiro ayo ekushanda achange ari nani mushure mekuumbwa. Nekuti inotora tekinoroji yepolymer fusion, inogutsa mamwe alloy zvivakwa zvinoda polymer.
Kunyanya kushandiswa kwePBT
1. Pamusana pehutano hwakanaka hwemuviri uye makemikari, PBT inowanzoshandiswa sechinhu chekuwedzera chechipiri chekuputira mafiber optical mukunze optical fiber cable.
2. Zvishandiso zvemagetsi nemagetsi: zvibatanidza, kushandura zvikamu, midziyo yemumba kana midziyo (kupisa kupisa, kupisa kwemoto, kuvhara magetsi, kuumba nyore uye kugadzirisa).
3. Mashandisirwo eminda yezvikamu zvemotokari: zvikamu zvemukati senge wiper brackets, control system mavharuvhu, nezvimwewo; zvemagetsi uye zvemagetsi zvikamu zvakadai semotokari ignition coil yakamonyoroka pombi uye zvine chekuita nemagetsi ekubatanidza.
4. General machine accessories application fields: chivharo chekombiyuta, mercury rambi chivharo, chivharo chesimbi yemagetsi, zvikamu zvemuchina wekubikira uye nhamba huru yemagiya, makamera, mabhatani, mabhomba emagetsi ewachi, magetsi emagetsi uye mamwe magomba emagetsi.
