Polybutylene tereftalate(PBT)) ni polyester yuzuyemo thermoplastic, muri rusange umweru usa n'amata, ifite granular solid ku bushyuhe bw'icyumba, ikoreshwa cyane mu gukora ibikoresho bya thermoplastic secondary coating.
Gusiga irangi rya fibre optique ni inzira y'ingenzi cyane mu gukora fibre optique. Mu buryo bworoshye, kongeramo urwego rwo kurinda ku gipfundikizo cy’ibanze cya fibre optique cyangwa urwego rwa buffer bishobora kunoza ubushobozi bwa fibre optique bwo kurwanya stress y’igihe kirekire n’iya radial no koroshya fibre optique nyuma yo gutunganya. Kubera ko ibikoresho byo gusiga biri hafi ya fibre optique, bigira ingaruka zikomeye ku mikorere ya fibre optique, bityo ibikoresho byo gusiga irangi bisabwa kugira coefficient ntoya yo kwaguka, crystalline nyinshi nyuma yo gusohora, chemical nziza n'ubushyuhe, inkuta zoroshye z'imbere n'inyuma z'urwego rwo gusiga irangi, imbaraga runaka zo gukurura na modulus ya Young, kandi bifite imikorere myiza. Gusiga irangi rya fibre muri rusange bigabanyijemo ibyiciro bibiri: igipfundikizo gito n'igipfundikizo gikomeye. Muri byo, ibikoresho byo gusiga irangi byakoreshejwe mu gipfundikizo gito ni urwego rwo gusiga irangi rwa kabiri rusohoka mu mwanya wo gusiga irangi hanze ya fibre yo gusiga irangi rya mbere.
PBT ni ibikoresho bisanzwe bikoreshwa mu gukata no gutunganya ibikoresho, bifite ubushobozi bwo gukora no gutunganya neza, bigabanya ubushuhe kandi bihendutse cyane. Bikoreshwa cyane cyane muPBTguhindura, gushushanya insinga za PBT, agasanduku, gushushanya filime n'ibindi bice. PBT ifite imiterere myiza ya mekanike (nk'ubudahangarwa bwo gukurura, ubudahangarwa bwo kunama, ubudahangarwa bwo ku ruhande), ubudahangarwa bwiza bwo gushonga, ubudahangarwa bw'amavuta, ubudahangarwa bwa shimi, na fibre paste, ubudahangarwa bw'insinga n'ibindi bice by'insinga bihuye neza, kandi bifite imikorere myiza yo gutunganya ibumba, ubudahangarwa buke bwo kwinjiza amazi, kandi bihendutse. Ibipimo byayo by'ingenzi by'imikorere ya tekiniki birimo: ubudahangarwa bw'imbere, imbaraga z'umusaruro, ubudahangarwa bwo kunama no gukurura, imbaraga z'ingaruka (notch), coefficient yo kwaguka kw'umurongo, ubudahangarwa bw'amazi, ubudahangarwa bwa hydrolysis n'ibindi.
Ariko, bitewe n'impinduka mu miterere y'insinga za fibre n'aho zikorera, hari byinshi bisabwa kugira ngo fibre buffer bushing ikoreshwe. Kurema cyane, kugabanuka guke, ingano nto yo kwaguka kw'umurongo muto, gukomera cyane, imbaraga nyinshi zo gukanda, ubushobozi bwiza bwo kurwanya imiti, imikorere myiza yo gutunganya, n'ibikoresho bihendutse ni byo ntego zigenzurwa n'abakora insinga za optique. Kuri ubu, hari inenge mu ikoreshwa n'igiciro cy'umuyoboro w'amashanyarazi ukozwe mu bikoresho bya PBT, kandi ibihugu by'amahanga byatangiye gukoresha ibikoresho bya PBT alloy kugira ngo bisimbuze ibikoresho bya PBT byuzuye, ibyo bikaba byaragize ingaruka nziza n'uruhare rwiza. Kuri ubu, ibigo byinshi bikomeye by'insinga zo mu gihugu birimo kwitegura cyane, ibigo by'ibikoresho bya insinga bikeneye udushya duhoraho mu ikoranabuhanga, ubushakashatsi no guteza imbere ibikoresho bishya.
Birumvikana ko mu nganda za PBT muri rusange, insinga za fiber optique zikorera igice gito cy'isoko rya PBT. Nk'uko amakuru aturuka mu nganda abivuga, mu nganda zose za PBT, igice kinini cy'isoko cyiganjemo amashami abiri y'imodoka n'ingufu. Ibikoresho bihuza, relays n'ibindi bicuruzwa bikozwe mu bikoresho bya PBT byahinduwe bikoreshwa cyane mu bikoresho by'imodoka, ibikoresho by'ikoranabuhanga n'amashanyarazi, ibikoresho bya mekanike n'ibindi, ndetse na PBT ifite ikoreshwa mu nganda z'imyenda, nko mu mavuta y'uburoso nayo akozwe muri PBT. Ibi bikurikira ni ikoreshwa rusange rya PBT mu nzego zitandukanye:
1. Ibikoresho by'ikoranabuhanga n'amashanyarazi
Ibikoresho bya PBT bikoreshwa cyane mu bijyanye n'amashanyarazi n'amashanyarazi, nko mu dusanduku tw'amashanyarazi, mu dusanduku, mu dusanduku tw'amashanyarazi n'ibindi bikoresho by'amashanyarazi byo mu rugo. Kubera ko ibikoresho bya PBT bifite ubushobozi bwo gukingira no kurwanya ubushyuhe bwinshi, birakwiriye cyane ku gishishwa, mu gice cyo hasi, mu gishishwa cyo gukingira no mu bindi bice by'ibikoresho by'amashanyarazi n'amashanyarazi. Byongeye kandi, ibikoresho bya PBT bishobora no gukoreshwa mu gukora igifuniko cy'inyuma cya LCD, mu gishishwa cya televiziyo n'ibindi.
2. Urwego rw'imodoka
Ibikoresho bya PBT nabyo bikoreshwa cyane mu bijyanye n'imodoka. Bitewe n'ibyiza byabyo byo kuba ubushyuhe bwinshi, ingese no kudashira, ibikoresho bya PBT bikoreshwa cyane mu gukora ibice by'imodoka, nka intake manifold, pompe y'amavuta, sensor housing, ibice bya sisitemu ya feri, nibindi. Byongeye kandi, ibikoresho bya PBT bishobora no gukoreshwa mu gushyiraho imitwe y'intebe z'imodoka, uburyo bwo guhindura intebe, nibindi.
3. Inganda z'imashini
Mu nganda z'imashini, ibikoresho bya PBT bikunze gukoreshwa mu gukora imikandara y'ibikoresho, swichi, utubuto, nibindi. Ibikoresho bya PBT bifite imbaraga nziza za mashini kandi birwanya kwangirika, bishobora kwihanganira imbaraga zitandukanye za mashini, kandi bifite ubudahangarwa bwiza bwa shimi, bikwiranye n'ibice bitandukanye mu nganda z'imashini.
4. Inganda zikora ibikoresho by'ubuvuzi
Ibikoresho bya PBT bifite ubushobozi bwo kwihanganira ubushyuhe bwinshi kandi bikagira ubushobozi bwo kudahinduka cyane mu binyabutabire, ibyo bikaba bikwiriye cyane mu gukora ibikoresho by’ubuvuzi. Urugero, ibikoresho bya PBT bishobora gukoreshwa mu gukora ibikoresho by’ubuvuzi, imiyoboro, imiyoboro, nibindi. Byongeye kandi, ibikoresho bya PBT bishobora no gukoreshwa mu gukora inshinge zo kwa muganga, imiyoboro n’ibikoresho bitandukanye byo kuvura.
5. Itumanaho ry'amajwi
Mu rwego rw'itumanaho ry'amatara, PBT ikoreshwa cyane mu gukora insinga z'amatara nk'ibikoresho bisanzwe byo mu ntoki. Byongeye kandi, ibikoresho bya PBT bikoreshwa cyane mu bikoresho by'amatara. Bitewe n'imiterere yabyo myiza y'amatara no kudashyuha cyane, ibikoresho bya PBT bikoreshwa mu gukora imiyoboro y'amatara, imiyoboro ikwirakwiza amatara, nibindi. Byongeye kandi, ibikoresho bya PBT bishobora no gukoreshwa mu gukora indorerwamo, indorerwamo, amadirishya n'ibindi bice by'amatara.
Ukurikije uko inganda zose zibibona, mu myaka ya vuba aha, ibigo bireba byiyemeje guteza imbere ikoreshwa ry’ikoranabuhanga rishya n’ibicuruzwa bishya, kandi PBT yateye imbere mu rwego rwo gukora neza, gukora no gukwirakwiza ibintu bitandukanye. Ingufu zo gukurura resin ya PBT nziza, imbaraga zo gukurura no gukurura modulus ni nke, ntizishobora gukoreshwa cyane mu rwego rw’inganda, bityo ku bijyanye n’ibyo inganda zikeneye, inganda zikoresha uburyo bwo guhindura kugira ngo zinoze imikorere ya PBT. Urugero, fibre y’ikirahure yongerwa kuri PBT - fibre y’ikirahure ifite ibyiza byo gukoresha cyane, inzira yoroshye yo kuzuza no ku giciro gito. Mu kongera fibre y’ikirahure kuri PBT, ibyiza by’umwimerere bya resin ya PBT birashyirwa mu bikorwa, kandi imbaraga zo gukurura, imbaraga zo gukurura n’imbaraga zo gukurura by’ibicuruzwa bya PBT birarushaho kunozwa cyane.
Muri iki gihe, uburyo bw'ingenzi mu gihugu no mu mahanga ni uguhindura copolymerization, guhindura inorganic material filling, ikoranabuhanga rya nanocomposite, guhindura blending, nibindi, kugira ngo kunoze imikorere ya PBT. Guhindura PBT ibikoresho byibanda ahanini ku bintu birimo imbaraga nyinshi, umuriro udashobora gushyuha cyane, warpage nke, imvura nke n'amashanyarazi make.
Muri rusange, ku bijyanye n'inganda zose za PBT, ubusabe bw'ikoreshwa mu nzego zitandukanye buracyari bwinshi cyane, kandi impinduka zitandukanye bitewe n'ubusabe bw'isoko nazo ni intego zihuriweho z'ubushakashatsi n'iterambere ry'ibigo by'inganda za PBT.
