Polybutylene terephthalate(PBT) yi-semi-crystalline, i-thermoplastic saturated polyester, ngokubanzi i-milky emhlophe, i-granular eqinile kwiqondo lobushushu begumbi, idla ngokusetyenziswa kwimveliso ye-optical cable thermoplastic secondary coating material.
I-Optical fibre coating yesibini yinkqubo ebaluleke kakhulu kwimveliso yefiber optical. Ukuthetha nje, ukongeza umaleko okhuselayo kwi-fiber optical primary coating okanye i-buffer layer inokuphucula amandla efiber optical ukumelana noxinzelelo lwe-longitudinal kunye ne-radial kunye nokuququzelela i-fiber optical post-processing. Ngenxa yokuba izinto zokugquma zisondele kwi-fiber optical, zinempembelelo enkulu ekusebenzeni kwe-fiber optical, ngoko ke izinto zokugquma ziyafuneka ukuba zibe ne-coefficient encinci yokwandisa i-linear, i-crystallinity ephezulu emva kwe-extrusion, iikhemikhali ezilungileyo kunye nokuzinza kwe-thermal, iindonga ezigudileyo zangaphakathi nangaphandle zomaleko wokugquma, amandla athile okuqina kunye nemodyuli yoMtsha, kwaye inenkqubo entle yokusebenza. Ukugquma iFayibha ngokuqhelekileyo kwahlulwe ngokwamacandelo amabini: isigqubuthelo esikhululekileyo kunye nesigqubuthelo esiqinileyo. Phakathi kwazo, imathiriyeli yesheyathi ekhululekileyo esetyenziswa kwityathanga ejijekileyo ngumaleko wesibini wokugquma okhutshelwe kwimeko yemikhono ekhululekileyo ngaphandle kwefiber yokuqala yokwambathisa.
I-PBT sisixhobo esixhaphakileyo semikhono esinemikhono egqwesileyo eneempawu ezigqwesileyo zokubunjwa kunye nokucubungula, ukufunxa ukufuma okuphantsi kunye nokusebenza kweendleko eziphezulu. Isetyenziswa kakhulu kwiPBTukuguqulwa, umzobo we-PBT wocingo, i-casing, umzobo wefilimu kunye nezinye iinkalo. I-PBT ineempawu ezintle zoomatshini (ezifana nokuxhathisa, ukugoba ukugoba, ukumelana noxinzelelo lwecala), ukuxhathisa okulungileyo kwe-solvent, ukuxhathisa i-oyile, ukuxhathisa i-chemical corrosion, kunye ne-fiber paste, i-cable paste kunye namanye amacandelo e-cable ahambelana kakuhle, kwaye inomsebenzi obalaseleyo wokubumba ukubunjwa, ukufunxa ukufuma okuphantsi, iindleko-esebenzayo. Imigangatho yayo ephambili yokusebenza kobugcisa ibandakanya: i-intrinsic viscosity, amandla esivuno, i-tensile kunye nokugoba imodyuli elastiki, amandla empembelelo (inotshi), i-coefficient yokwandiswa komgca, ukufunxwa kwamanzi, ukuxhathisa i-hydrolysis njalo njalo.
Nangona kunjalo, ngotshintsho lwesakhiwo sentambo yefayibha kunye nendawo yokusebenza, iimfuno ezingaphezulu zibekwe phambili kwi-fiber buffer bushing. I-crystallization ephezulu, i-shrinkage ephantsi, i-coefficient yokwandisa i-linear ephantsi, ukuqina okuphezulu, amandla acinezelayo aphezulu, ukuchasana kweekhemikhali okugqwesileyo, ukusebenza kakuhle kokusebenza, kunye nexabiso eliphantsi lezinto ezizinjongo ezilandelwa ngabavelisi bentambo ye-optical cable. Okwangoku, kukho ukusilela kwisicelo kunye nexabiso le-tube ye-beam eyenziwe ngezinto ze-PBT, kwaye amazwe angaphandle aqalise ukusebenzisa izixhobo ze-PBT ze-alloy ukuthatha indawo ye-PBT ecocekileyo, eye yadlala umphumo omuhle kunye nendima. Okwangoku, iinkampani ezininzi zeentambo zasekhaya zilungiselela ngenkuthalo, iinkampani zemathiriyeli yentambo zifuna ukuphuculwa okuqhubekayo kwetekhnoloji, uphando kunye nophuhliso lwemathiriyeli emitsha.
Ngokuqinisekileyo, kwishishini lonke le-PBT, izicelo ze-fiber optic cable zithatha indawo encinci ye-PBT market. Ngokwemithombo yoshishino, kuyo yonke imboni ye-PBT, uninzi lwesabelo semarike sihlala ikakhulu ngamasimi amabini eemoto kunye namandla. Iziqhagamshelo, ii-relays kunye nezinye iimveliso ezenziwe ngezinto eziguquliweyo ze-PBT zisetyenziswa kakhulu kwiimoto, kwizixhobo zombane kunye nezombane, izixhobo zoomatshini kunye nezinye iindawo, kwaye i-PBT inezicelo kwibala le-textile, njenge-bristles of toothbrushes nayo yenziwe nge-PBT. Oku kulandelayo kukusetyenziswa ngokubanzi kwePBT kwiinkalo ezahlukeneyo:
1.Imimandla yombane kunye nombane
Izinto ze-PBT zisetyenziswa ngokubanzi kwimimandla yombane kunye nombane, njengeesokethi zamandla, iiplagi, iisokethi zombane kunye nezinye iindawo zombane zasekhaya. Kuba imathiriyeli ye-PBT inokusebenza kakuhle kokugquma kunye nokumelana nobushushu obuphezulu, ifaneleke kakhulu iqokobhe, isibiyeli, iphepha lokugquma kunye nezinye iindawo zezixhobo zombane kunye nombane. Ukongeza, imathiriyeli ye-PBT ingasetyenziselwa ukwenza isikrini se-LCD sesigqubuthelo sangasemva, iqokobhe likamabonakude njalo njalo.
2.Indawo yeemoto
Izinto ze-PBT nazo zisetyenziswa ngokubanzi kwintsimi yeemoto. Ngenxa yeenzuzo zayo zokushisa okuphezulu, ukubola kunye nokumelana nokunxiba, izinto ze-PBT zisetyenziswa ngokubanzi ekwenzeni iindawo zemoto, ezifana ne-intake manifold, i-oil pump housing, i-sensor yezindlu, i-system components components, njl. Ukongeza, izinto ze-PBT nazo zingasetyenziselwa i-headrests yesihlalo semoto, iindlela zokulungisa isihlalo, njl.
3.Ishishini loomatshini
Kumashishini oomatshini, izixhobo ze-PBT zihlala zisetyenziselwa ukwenza izixhobo zokuphatha izixhobo, iiswitshi, amaqhosha, njl njl. Izinto ze-PBT zinamandla abalaseleyo omatshini kunye nokumelana nokunxiba, kunokumelana nemikhosi eyahlukeneyo yoomatshini, kwaye inokumelana nekhemikhali elungileyo, ifanelekile kwiindawo ezahlukeneyo kwishishini lomatshini.
4.Ishishini lezixhobo zonyango
Izinto ze-PBT zinokumelana nokushisa okuphezulu kunye nokuzinza kweekhemikhali eziphezulu, ezifanele kakhulu ukuveliswa kwezixhobo zonyango. Ngokomzekelo, izinto ze-PBT zingasetyenziselwa ukwenza izindlu zezixhobo zonyango, iipayipi, izixhumi, njl. Ukongeza, izinto ze-PBT zingasetyenziselwa ukwenza iisirinji zonyango, iiseti ze-infusion kunye nezixhobo ezahlukeneyo zonyango.
5. Unxibelelwano lwamehlo
Kwinkalo yonxibelelwano lwe-optical, i-PBT isetyenziswa ngokubanzi kwi-optical cable yokuvelisa njengento eqhelekileyo ye-sleeve ekhululekile. Ukongezelela, izinto ze-PBT zisetyenziswa ngokubanzi kwizixhobo ezibonakalayo. Ngenxa yezinto ezintle ze-optical kunye nokumelana nokushisa okuphezulu, izinto ze-PBT zisetyenziselwa ukwenza i-fiber optical connectors, iifreyimu zokusabalalisa i-fiber optical, njl. Ukongeza, izinto ze-PBT zingasetyenziselwa ukwenza iilensi, izibuko, iWindows kunye nezinye izinto ezibonakalayo.
Ngokombono walo lonke ishishini, kwiminyaka yakutshanje, amashishini afanelekileyo azibophelele ekuphuhliseni iintlobo ezahlukeneyo zetekhnoloji entsha kunye neemveliso ezintsha, kwaye i-PBT iye yaphuhliswa kwindlela yokusebenza okuphezulu, ukusebenza kunye nokwahlukana. I-PBT ecocekileyo ye-resin yamandla e-tensile, amandla okugoba kunye ne-modulus yokugoba iphantsi, ayinakusetyenziswa ngokubanzi kwintsimi yoshishino, ngoko kwiimfuno zecandelo loshishino, imboni ngokuguqulwa kokuphucula ukusebenza kwe-PBT. Ngokomzekelo, i-fiber yeglasi yongezwa kwi-PBT - i-fiber yeglasi ineenzuzo zokusebenziseka okunamandla, inkqubo yokuzalisa elula kunye neendleko eziphantsi. Ngokongeza i-fiber yeglasi kwi-PBT, iingenelo zokuqala ze-PBT resin zifakwa ekudlaleni, kwaye amandla okuqina, amandla okugoba kunye namandla empembelelo yenotshi yeemveliso ze-PBT ziphuculwe kakhulu.
Okwangoku, iindlela eziphambili zasekhaya nakwamanye amazwe ziyi-copolymerization modification, i-inorganic material filling modification, iteknoloji ye-nanocomposite, ukuguqulwa kokudibanisa, njl., Ukuphucula ukusebenza okubanzi kwe-PBT. Ukuguqulwa kwezinto ze-PBT kugxininise kakhulu kwiinkalo zamandla aphezulu, i-flame retardant ephezulu, i-warpage ephantsi, i-precipitation ephantsi kunye ne-dielectric ephantsi.
Ngokubanzi, ngokubhekiselele kuyo yonke imboni ye-PBT, imfuno yesicelo kwiinkalo ezahlukeneyo zisabonakala kakhulu, kwaye ukuguqulwa okuhlukeneyo ngokwemfuno yemarike kukwakhona uphando oluqhelekileyo kunye neenjongo zophuhliso lwamashishini oshishino lwe-PBT.
