Polybutylene terephthalate(PBT)) ipolyester yakaguta ine semi-crystalline, inowanzova chena yakaita semukaka, granular solid patembiricha yemumba, inowanzoshandiswa mukugadzira optical cable thermoplastic secondary coating material.
Kuputira fiber yechipiri inzira yakakosha mukugadzirwa kwefiber ye optical. Kutaura zviri nyore, kuwedzera layer yekudzivirira kune optical fiber primary coating kana buffer layer kunogona kuvandudza kugona kwe fiber ye optical kudzivirira kushushikana kwenguva refu uye radial uye kuita kuti optical fiber ishande zvakanaka mushure mekugadzirisa. Nekuti zvinhu zvekuputira zviri pedyo ne fiber ye optical, zvine simba guru pakushanda kwe fiber ye optical, saka zvinhu zvekuputira zvinodiwa kuti zvive ne linear expansion coefficient diki, high crystallinity mushure me extrusion, good chemical and thermal stability, smooth inside and outer walls of the coating layer, tensile strength uye Young's modulus, uye zvine process performance yakanaka. Kuputira fiber kunowanzo kamurwa muzvikamu zviviri: loose cover uye tight cover. Pakati pazvo, loose sheath material inoshandiswa mu loose sheath coating i secondary coating layer extruded in loose sleeve situation outside the primary coating fiber.
PBT chinhu chinowanzo shandiswa nemaoko asina kusimba, chine hunhu hwakanaka hwekugadzira nekugadzirisa, hunyoro hushoma uye hunoshanda zvakanaka. Chinonyanya kushandiswa muPBTkugadziriswa, kudhirowa kwewaya yePBT, casing, kudhirowa kwefirimu nezvimwe zvinhu. PBT ine hunhu hwakanaka hwemakanika (senge kusimba kwekudhonza, kusimba kwekukotama, kusimba kwekumanikidzwa kwedivi), kusimba kwekunyungudutsa, kusimba kwemafuta, kusimba kwekuora kwemakemikari, uye kusimba kwefiber, kusimba kwetambo nezvimwe zvikamu zvetambo zvine hukama hwakanaka, uye ine kugona kwakanaka kwekugadzirisa molding, kusimba kwekunyorova kwakaderera, uye isingadhuri. Mitemo yayo mikuru yehunyanzvi hwekuita inosanganisira: kusimba kwemukati, simba rekukura, kusimba kwekukotama uye kukotama elastic modulus, simba rekukanganisa (notch), coefficient yekuwedzera kwemutsara, kusimba kwemvura, kusimba kwehydrolysis nezvimwewo.
Zvisinei, nekuchinja kwechimiro chetambo yefiber nenzvimbo yekushanda, zvinodiwa zvakawanda zvinoiswa pamberi pe fiber buffer bushing. Kugadzirwa kwakasimba kwe crystallization, low shrinkage, low linear expansion coefficient, high toughness, high compressive strength, expansion yakanakisa yemakemikari, kugona kwakanaka kwekugadzirisa, uye zvinhu zvakachipa ndizvo zvinangwa zvinoteverwa nevagadziri vetambo dze optical. Parizvino, pane zvikanganiso mukushandiswa uye mutengo we tube ye beam yakagadzirwa nezvinhu zvePBT, uye nyika dzekunze dzakatanga kushandisa zvinhu zvePBT alloy kutsiva zvinhu zvePBT zvakachena, izvo zvave nemhedzisiro yakanaka uye basa rakanaka. Parizvino, makambani makuru e cable emuno ari kugadzirira, makambani e cable anoda hunyanzvi hwetekinoroji hunoramba huchienderera mberi, kutsvagisa nekugadzira zvinhu zvitsva.
Ehe, muindasitiri yePBT yese, mashandisirwo etambo dzefiber optic anongotora chikamu chidiki chemusika wePBT. Sekureva kwezvinyorwa zveindasitiri, muindasitiri yese yePBT, mugove wemusika unonyanya kugarwa neminda miviri yemotokari nemagetsi. Zvinobatanidza, marelay nezvimwe zvigadzirwa zvakagadzirwa nezvinhu zvakagadziriswa zvePBT zvinoshandiswa zvakanyanya mumidziyo yemotokari, yemagetsi neyemagetsi, michina yemakanika nedzimwe nzvimbo, uye kunyange PBT ine mashandisirwo mumunda wemachira, senge mabhurashi emabhurashi emazino akagadzirwawo nePBT. Aya ndiwo mashandisirwo akajairika ePBT muminda dzakasiyana-siyana:
1. Minda yemagetsi nemagetsi
Zvinhu zvePBT zvinoshandiswa zvakanyanya muminda yemagetsi nemagetsi, zvakaita semasoketi emagetsi, mapulagi, masoketi emagetsi nezvimwe zvikamu zvemagetsi zvemumba. Nekuti zvinhu zvePBT zvine simba rakanaka rekudzivirira kupisa uye zvinodzivirira kupisa kwakanyanya, zvakakodzera kwazvo shell, bracket, insulation sheet nezvimwe zvikamu zvemidziyo yemagetsi nemagetsi. Pamusoro pezvo, zvinhu zvePBT zvinogonawo kushandiswa kugadzira LCD screen back cover, TV shell nezvimwewo.
2. Munda wemotokari
Zvinhu zvePBT zvinoshandiswawo zvakanyanya mumunda wemotokari. Nekuda kwezvakanaka zvayo zvekupisa kwakanyanya, ngura uye kusakara, zvinhu zvePBT zvinoshandiswa zvakanyanya mukugadzira zvikamu zvemotokari, zvakaita se intake manifold, oil pump housing, sensor housing, brake system components, nezvimwewo. Pamusoro pezvo, zvinhu zvePBT zvinogonawo kushandiswa pakuisa misoro yemota, kugadzirisa zvigaro, nezvimwewo.
3. Indasitiri yemichina
Muindasitiri yemichina, zvinhu zvePBT zvinowanzoshandiswa kugadzira mibato yezvishandiso, maswichi, mabhatani, nezvimwewo. Zvinhu zvePBT zvine simba guru remichina uye zvinodzivirira kupera, zvinogona kutsungirira masimba akasiyana-siyana emuchina, uye zvine simba rakanaka rekudzivirira ngura yemakemikari, zvakakodzera zvikamu zvakasiyana-siyana mumunda weindasitiri yemichina.
4. Indasitiri yemidziyo yekurapa
Zvinhu zvePBT zvine simba rekudzivirira kupisa kwakanyanya uye kugadzikana kwakanyanya kwemakemikari, izvo zvakakodzera kugadzirwa kwemidziyo yekurapa. Semuenzaniso, zvinhu zvePBT zvinogona kushandiswa kugadzira dzimba dzemidziyo yekurapa, mapaipi, zvinobatanidza, nezvimwewo. Pamusoro pezvo, zvinhu zvePBT zvinogona kushandiswawo kugadzira sirinji dzekurapa, seti dzeinfusion uye zvishandiso zvakasiyana-siyana zvekurapa.
5. Kutaurirana kwemaziso
Munyaya yekutaurirana kwemaziso, PBT inoshandiswa zvakanyanya mukugadzira tambo dzemaziso sechinhu chinowanzo shandiswa nemaoko asina kusimba. Pamusoro pezvo, zvinhu zvePBT zvinoshandiswa zvakanyanya mumidziyo yemaziso. Nekuda kwehunhu hwayo hwakanaka hwemaziso uye kuramba kupisa kwakanyanya, zvinhu zvePBT zvinoshandiswa kugadzira zvinobatanidza fiber dzemaziso, mafuremu ekugovera fiber dzemaziso, nezvimwewo. Pamusoro pezvo, zvinhu zvePBT zvinogonawo kushandiswa kugadzira malenzi, magirazi, mahwindo nezvimwe zvikamu zvemaziso.
Kubva pamaonero eindasitiri yese, mumakore achangopfuura, mabhizinesi akakodzera akazvipira mukuvandudza matekinoroji matsva nezvigadzirwa zvitsva zvakasiyana-siyana, uye PBT yakabudirira mukuita kwepamusoro-soro, kushanda uye kusiyanisa. Simba rekudhonza resin rePBT rakachena, simba rekukotama uye modulus yekukotama zvakaderera, hazvigone kushandiswa zvakanyanya mumunda wemaindasitiri, saka nekuda kwezvinodiwa zvemunda wemaindasitiri, indasitiri kuburikidza nekushandura kuti ivandudze mashandiro ePBT. Semuenzaniso, fiber yegirazi inowedzerwa kuPBT - fiber yegirazi ine zvakanakira zvekushandiswa kwakasimba, maitiro ekuzadza ari nyore uye mutengo wakaderera. Nekuwedzera fiber yegirazi kuPBT, zvakanakira zvepakutanga zvePBT resin zvinounzwa, uye simba rekudhonza, simba rekukotama uye simba rekushaya simba rezvigadzirwa zvePBT zvinovandudzwa zvakanyanya.
Parizvino, nzira huru dziri kushandiswa munyika nekune dzimwe nyika dzinosanganisira kugadzirisa copolymerization, kugadzirisa inorganic material filling modification, nanocomposite technology, blending modification, nezvimwewo, kuti PBT ishande zvakanaka. Kugadzirisa zvinhu zvePBT kunonyanya kutarisa zvinhu zvine simba guru, zvinodzora moto zvakanyanya, warpage shoma, mvura shoma uye dielectric shoma.
Kazhinji, maererano neindasitiri yese yePBT, kudiwa kwekushandiswa muminda yakasiyana-siyana kuchiri kukuru, uye shanduko dzakasiyana-siyana zvichienderana nekudiwa kwemusika ndizvo zvinangwa zvekutsvaga nekusimudzira zvemakambani ePBT.
