Iyo imikandara isanzwe inaniwe, Kevlar irabyitwaramo neza

Mu nganda zishyushye cyane—inganda zikora ibirahure, itunganywa ry'ibyuma, n'imiyoboro ikoreshwa mu gutunganya ubushyuhe—imikandara isanzwe ikoreshwa mu gutwara ibintu irangirika vuba bitewe n'ubushyuhe bwinshi, bigatuma habaho igihe gihenze cyo gukora no gusimbuza kenshi. Ku bayobozi b'inganda, abahanga mu gutanga amasoko, n'abahuza ibikoresho bahura n'ibibazo bikomeye by'ubushyuhe, ikibazo ni ingenzi: Umukandara wa Kevlar ukoreshwa mu gutwara ibintu ushyushye cyane ni iki, kandi kuki urusha abandi uburyo busanzwe?

Umukandara wa Kevlar ushyushye cyane ni umuti wo gufunga ukozwe mu nganda ukoresheje fibre ya DuPont™ Kevlar® aramid—cyangwa uruvange rwa Kevlar hamwe n'ibyuma bitarangwamo ifumbire na PBO—wagenewe kwihanganira ubushyuhe buhoraho kuva kuri 260°C kugeza ku bushyuhe butunguranye bwa 550°C mu gihe ukomeza gukomera no kudahindagurika. Bitandukanye n'imikandara ya polyester/nylon (EP) cyangwa imikandara y'icyuma irambura, irangirika, cyangwa igatakaza ubuziranenge mu gihe cy'ubushyuhe, imikandara ishingiye kuri Kevlar imara igihe kirekire mu bidukikije bishyushye cyane.

Akamaro ka Kevlar

Kevlar ni fibre ya aramid ikomeye kandi yoroheje yakozwe na DuPont, itanga:

• Ubudahangarwa budasanzwe bw'ubushyuhe: Gukomeza gukora kugeza kuri 260°C; uburebure bw'ako kanya bugera kuri 550°C
• Ingufu zo gukurura cyane: Ikora ibintu biremereye idakura cyangwa ngo ivunike
• Uburebure buke: Ubusanzwe buri munsi ya 0.5%, bigatuma habaho ubusugire bw'ibipimo munsi y'umutwaro
• Yoroheje: Yoroshye kugeza kuri 30% ugereranyije n'imikandara y'icyuma ifite imbaraga zingana, bigabanya ikoreshwa ry'ingufu
• Ubudahangarwa bw'imiti n'ubushyuhe: Ntibwangizwa n'umwuka w'amazi, imyunyu ngugu yangiza, n'ibindi bintu byinshi bihumanya

Uruvange rw'ibirungo kugira ngo rurusheho kunoza imikorere

Imikandara myinshi ya Kevlar conveyor ikoresha ubushyuhe bwinshi irimo ibindi bikoresho kugira ngo yongere imiterere yihariye:

Ubwoko bw'imikandara ya Kevlar Conveyor ishyushye cyane

1. Imikandara ya Kevlar iboshye neza

Yakozwe hakoreshejwe uburyo bwo kuboha bufite ubucucike bwinshi kandi bufite ibyiciro byinshi. Ubunini busanzwe buri hagati ya mm 0.7 na mm 6, ubugari bugera kuri mm 500 cyangwa zirenga. Iyi mikandara irakomeye, irakomeye, kandi irinda ibimenyetso cyangwa gushyuha ku bintu bigezwaho.

2. Imikandara ya Kevlar Mesh itwikiriwe na PTFE

Umukandara wa Kevlar utwikiriwe na PTFE (Teflon) utanga ubuso budafata kandi burwanya imiti. Iyi mikandara ifunguye ni myiza mu kumisha ifuru, gukaraba PCB, no kumisha imyenda. Ingufu zo gukurura zishobora kugera kuri 3,500/3,300 N/5cm.

3. Imikandara ya Kevlar Felt

Ibyuma bya Kevlar bifite urwego rwinshi rw’ubushyuhe bifite urwego 5 cyangwa zirenga. Ubushyuhe bushobora kugabanuka kugeza kuri 510°C, ubugari buri hagati ya 5mm na 14mm. Biboneka mu buryo butagira iherezo cyangwa hakoreshejwe ibifunga bya mashini.

4. Imikandara y'imyenda ya Kevlar ipfutse kuri PTFE

Igitambaro cyo hasi cya Kevlar gisizwe na resin ya PTFE kugira ngo gikoreshwe gisaba ubuso budafatana kandi kidafata imiti. Ingano y'ubushyuhe: -140°C kugeza 360°C. Ingufu zo gukurura kugeza kuri 1.500/1.250 N/cm.

Porogaramu z'ingenzi zikoreshwa n'inganda

Gukora Ikirahure

Imikandara ya Kevlar ikoreshwa cyane mu bushyuhe bwinshi. Imikandara itwara ibintu bishyushye by'ibirahure—stemware, amadirishya y'imashini imesa, ibikoresho byo ku meza—kuva ku gukora imashini zicapa kugeza ku byuma bishyushya, aho ubushyuhe buba bukabije kandi ubushyuhe bukabije butera ibyago bihoraho. Ubushyuhe bw'umukandara butuma ubushyuhe budashobora guhagarara, gukaraba cyangwa guhinduka kw'ibirahure.

Ubuhanga mu by'ibyuma no gutunganya ibyuma

Gutwara impapuro z'icyuma gishyushye, imashini zisukwa, amabuye y'agaciro acukuwe, na clinker. Mu nganda z'icyuma, imikandara ya Kevlar ifata ibikoresho bishyushye bivuye mu nzira zihoraho zo gucukura cyangwa gukaranga, igakomeza kuba nziza aho imikandara isanzwe ya kabutura yakomera ikameneka. Imikandara ya Super-K® ishingiye kuri EPDM ni ubundi buryo burwanya ubushyuhe, ariko Kevlar itanga imbaraga zo gukurura no kubaka byoroshye.

Ubucukuzi bw'amabuye y'agaciro n'inganda zikomeye

Imikandara yo gucukura ikoresheje Kevlar® cassava isimbuza imikandara isanzwe ya polyester/nylon n'imigozi y'icyuma. Ibyiza birimo kongera igihe cyo kubaho, kugabanuka k'ubudahangarwa bwo kuzingurura, ikoreshwa ry'ingufu nke, no kugabanuka k'udutsi duto. Imiterere yoroheje igabanya ibisabwa mu miterere y'ibikoresho n'ikiguzi cyo kubikoresha.

Ibikorwa byo kumisha no gukamura

Imikandara ya Kevlar mesh ikoreshwa muri PTFE ikoreshwa muri:

• Utwumisha imyenda duto two mu buriri buciriritse hamwe n'imirongo ihuza imyenda
• Imiyoboro ikoresha infrared kure
• Amafuru yo kumisha PCB
• Imiyoboro y'amazi ku biribwa mu nganda
• Gupakira lamination no gushyira imyenda mu buryo bwo kugabanya ubushyuhe

Igishushanyo mbonera cy'urukuta rufunguye cyemerera umwuka gutembera mu gihe ubuso bwa PTFE budafata butuma ibintu birekurwa byoroshye.

Ibisobanuro bya tekiniki: Icyo wakwitaho

Mu gihe usuzuma imikandara ya Kevlar ikoresha ubushyuhe bwinshi, tekereza kuri ibi bipimo by'ingenzi:

Ubudahangarwa bw'ubushyuhe

• Ubushyuhe buhoraho mu gukora: Ubusanzwe 260°C–400°C bitewe n'inyubako
• Ubushyuhe bw'agahenge ako kanya: Kugeza kuri 550°C–600°C ku bivange bya PBO
• Ubushyuhe buke: Hasi nka -196°C kuri verisiyo za PTFE

Imbaraga zo Gufata

• Imikandara ya Kevlar mesh: 3,500/3,300 N/5cm
• Imikandara y'imyenda ya Kevlar: Kugeza kuri 1.500/1.250 N/cm
• Uburebure buke (≤0.5%) butuma habaho uburimbane burambye

Ingano

• Ubugari: Kugeza kuri 4.000mm ku mikandara y'urushundura; ubusanzwe 300–500mm ku mikandara iboshye
• Ubunini: 0.7mm kugeza kuri 6mm ku boshye; kugeza kuri 14mm ku boshye; 0.08mm kugeza kuri 1.5mm ku myenda ipfutse

Impamyabushobozi

Shaka imicungire y'ubuziranenge ya ISO 9001 n'ikimenyetso cya CE kugira ngo urebe niba i Burayi bwubahiriza amategeko. Ku bijyanye n'ubucukuzi bw'amabuye y'agaciro, genzura niba wujuje ibisabwa n'amahame agenga inganda.

Uburyo bwo guhitamo umukandara wa Kevlar ufite ubushyuhe bwinshi

1. Suzuma ibikenewe mu bushyuhe

Sobanura ubushyuhe bwawe buhoraho ntarengwa n'ubushyuhe bw'ako kanya. Niba inzira yawe irengeje 260°C buri gihe, tekereza ku byuma bivanze bya stainless steel/PBO cyangwa ibyuma by'ubwubatsi.

2. Suzuma ibisabwa na tekiniki

• Uburemere bw'umutwaro n'uburebure bw'umutwaro
• Uburibwe bukabije kandi bushobora gutuma umuntu acika cyangwa agacika
• Imbaraga zisabwa zo gukurura no kurekura

3. Kumenya Imiterere y'Umukandara

• Ufunguye mesh: Ku bijyanye no kumisha, ibikenewe mu gusohora umwuka
• Iboshye mu buryo butambitse: Ikoreshwa mu birahure, icyuma, no mu bikoresho biremereye
• Felti: Ku bushyuhe bukabije cyangwa ibikorwa byihariye
• Ifite PTFE: Ku bintu bidafata kandi birwanya imiti

4. Tekereza ku kiguzi cyose cy'umutungo

Nubwo ikiguzi cya mbere gishobora kuba kiri hejuru y’imikandara isanzwe, igihe kirekire cyo kuyikoresha, igihe gito cyo kuyikoresha, no kuyikoresha ingufu nke bitanga agaciro gakomeye mu gihe kirekire.

Umwanzuro: Agaciro k'ingamba z'imikandara ya Kevlar ifite ubushyuhe bwinshi

Umukandara wa Kevlar ushyushye cyane ni ikintu kirenze gusimbura ikindi—ni ishoramari rikomeye mu mikorere myiza. Mu kwihanganira ubushyuhe bukabije, kubungabunga imiterere y’imodoka, no kwirinda kwangirika, imikandara ya Kevlar igabanya igihe cyo kudakora, igabanya ikiguzi cyo kubungabunga, kandi ikongera ireme ry’ibicuruzwa mu nganda zikora ibintu byinshi.

Ku nganda zishyira imipaka ku muvuduko n'ubushyuhe bw'umusaruro, ibikoresho byo guteka bikozwe muri Kevlar ni byo bipimo bishya. Nk'uko umwe mu bakora ibikoresho yabivuze, iri koranabuhanga "rigaragaza intambwe ikomeye mu gukemura ibibazo bigoye byo gukora imiyoboro ikoresha ubushyuhe bwinshi".
