Malamba Okhazikika Akalephera, Kevlar Amapambana

M'mafakitale omwe kutentha kwake kuli kwakukulu—kupanga magalasi, kukonza zitsulo, ndi mizere yotenthetsera—malamba oyendera magetsi amawonongeka msanga chifukwa cha kutentha kwambiri, zomwe zimapangitsa kuti pakhale nthawi yotsika mtengo komanso kusintha zinthu pafupipafupi. Kwa oyang'anira mafakitale, mainjiniya ogula zinthu, ndi ophatikiza zida omwe akukumana ndi mavuto aakulu a kutentha, funso ndi lofunika kwambiri: Kodi lamba woyendera magetsi wa Kevlar wotentha kwambiri ndi chiyani, ndipo n'chifukwa chiyani umachita bwino kuposa njira zina zamakono?

Lamba wonyamula katundu wa Kevlar wotentha kwambiri ndi njira yothetsera lamba wa mafakitale yopangidwa ndi ulusi wa DuPont™ Kevlar® aramid—kapena kuphatikiza kwa Kevlar ndi chitsulo chosapanga dzimbiri ndi ulusi wa PBO—kopangidwa kuti kupirire kutentha kosalekeza kuyambira 260°C mpaka kufika pa 550°C nthawi yomweyo pamene kuli kolimba kwambiri komanso kukhazikika kwa miyeso. Mosiyana ndi malamba a polyester/nayiloni (EP) kapena achitsulo omwe amatambasula, kuwononga, kapena kutaya umphumphu akamatenthedwa, malamba okhala ndi Kevlar amapereka moyo wautali m'malo otentha kwambiri.

Zomwe ZimapangaMalamba Onyamula KevlarKodi Zimalimbana ndi Kutentha Kwambiri?

Ubwino wa Kevlar

Kevlar ndi ulusi wa aramid wolimba komanso wopepuka womwe unapangidwa ndi DuPont, womwe umapereka:

• Kukana kutentha kwapadera: Kugwira ntchito mosalekeza mpaka 260°C; mapiri othamanga nthawi yomweyo amafika 550°C
• Mphamvu yolimba kwambiri: Imanyamula katundu wolemera popanda kutambasula kapena kusweka
• Kutalikirana kochepa: Nthawi zambiri kumakhala kochepera 0.5%, kuonetsetsa kuti zinthuzo zimakhala zokhazikika pansi pa katundu
• Wopepuka: Wopepuka mpaka 30% kuposa malamba achitsulo a chingwe cha waya omwe ali ndi mphamvu yofanana, zomwe zimachepetsa kugwiritsa ntchito mphamvu
• Kukana mankhwala ndi dzimbiri: Sizimakhudzidwa ndi nthunzi ya madzi, mchere wowononga, ndi mankhwala ambiri

Mitundu ya Malamba Onyamula Ma Kevlar Otentha Kwambiri

1. Malamba Olukidwa ndi Kevlar

Yopangidwa pogwiritsa ntchito njira zolukira zolemera kwambiri komanso zogwiritsidwa ntchito m'magawo ambiri. Kukhuthala kwanthawi zonse kumayambira pa 0.7mm mpaka 6mm, ndipo m'lifupi mwake ndi mpaka 500mm kapena kuposerapo. Malamba awa ndi olimba, olimba, ndipo amaletsa zizindikiro kapena kutentha kwambiri pazinthu zonyamulidwa.

2. Malamba a Kevlar Mesh Ophimbidwa ndi PTFE

Chotsukira cha Kevlar chokhala ndi PTFE (Teflon) chimapereka malo osamata komanso osagwira mankhwala. Malamba otseguka awa ndi abwino kwambiri powumitsa uvuni, kupopera PCB, ndi kuuma kwa nsalu. Mphamvu yokoka imatha kufika 3,500/3,300 N/5cm.

3. Malamba a Kevlar Felt

Kapangidwe ka felti ya Kevlar yokhala ndi zigawo zisanu kapena kuposerapo zolimbitsa. Kukana kutentha mpaka 510°C, ndi makulidwe kuyambira 5mm mpaka 14mm. Imapezeka yolukidwa mosalekeza kapena yokhala ndi zomangira zamakina.

4. Malamba a Nsalu ya Kevlar Yokutidwa ndi PTFE

Nsalu ya Kevlar yokutidwa ndi utomoni wa PTFE kuti igwiritsidwe ntchito pa malo osamatirira komanso kukana mankhwala. Kutentha: -140°C mpaka 360°C. Mphamvu yokoka mpaka 1,500/1,250 N/cm.

Ntchito Zofunika Kwambiri ndi Makampani

Kupanga Magalasi

Kugwiritsa ntchito kwambiri malamba a Kevlar conveyor okhala ndi kutentha kwambiri. Malamba amanyamula zinthu zagalasi lotentha—stemware, mawindo ochapira, ndi ziwiya za patebulo—kuyambira kupanga makina osindikizira mpaka ma annealing lehrs, komwe kutentha kumakhala koopsa kwambiri ndipo kutentha kumakhala koopsa nthawi zonse. Kukana kutentha kwa lamba kumalepheretsa kulemba, kuphimba, kapena kusintha mawonekedwe a magalasi.

Kukonza Zitsulo ndi Zitsulo

Kutumiza mapepala otentha achitsulo, zotayidwa zotayidwa, miyala yosungunuka, ndi clinker. M'mafakitale achitsulo, malamba a Kevlar amagwira ntchito yotenthetsa zinthu kuchokera ku njira zopititsira patsogolo kapena zoyeretsera, kusunga umphumphu pomwe malamba wamba a rabara angaume ndikusweka. Malamba a Super-K® ochokera ku EPDM ndi njira ina yosatentha, koma Kevlar imapereka mphamvu yokoka komanso kapangidwe kopepuka.

Migodi ndi Makampani Olemera

Malamba oyendera magetsi okhala ndi Kevlar® carcass amalowa m'malo mwa malamba a polyester/nayiloni ndi achitsulo. Ubwino wake ndi monga kukhala ndi moyo wautali, kukana kugwedezeka, kugwiritsa ntchito mphamvu zochepa, komanso ma splices ochepa. Kapangidwe kopepuka kamachepetsa kufunika kwa kapangidwe ka zida ndi ndalama zogwirira ntchito.

Ntchito Zowumitsa ndi Kukonza

Malamba a Kevlar okhala ndi PTFE amagwiritsidwa ntchito mu:

• Zipangizo zoumitsira nsalu zokhala ndi bedi lathyathyathya komanso mizere yolumikizirana
• Ma ngalande ochiritsira a infrared kutali
• Ma uvuni owumitsa a PCB
• Mizere yochepetsera madzi m'thupi m'mafakitale
• Kupaka lamination ndi kuyika zovala

Kapangidwe ka mauna otseguka kamalola mpweya kuyenda pomwe pamwamba pa PTFE yosamata kumatsimikizira kuti zinthuzo zimatulutsidwa mosavuta.

Zofunikira paukadaulo: Zoyenera Kuyang'ana

Mukayang'ana malamba a Kevlar conveyor otentha kwambiri omwe mungagwiritse ntchito, ganizirani izi:

Kukana Kutentha

• Kutentha kogwira ntchito kosalekeza: Kawirikawiri 260°C–400°C kutengera kapangidwe kake
• Kutentha kwakukulu nthawi yomweyo: Mpaka 550°C–600°C pa zosakaniza za PBO
• Malire otsika kutentha: Otsika mpaka -196°C pa mitundu yokhala ndi zokutidwa ndi PTFE

Kulimba kwamakokedwe

• Malamba a Kevlar mesh: 3,500/3,300 N/5cm
• Malamba a nsalu ya Kevlar: Mpaka 1,500/1,250 N/cm
• Kutalikirana kochepa (≤0.5%) kumatsimikizira kukhazikika kwa miyeso

Miyeso

• M'lifupi: Mpaka 4,000mm pa malamba a maukonde; nthawi zambiri 300–500mm pa malamba oluka athyathyathya
• Kukhuthala: 0.7mm mpaka 6mm pa nsalu yolukidwa; mpaka 14mm pa nsalu yolukidwa; 0.08mm mpaka 1.5mm pa nsalu zophimbidwa

Ziphaso

Yang'anani kasamalidwe ka khalidwe la ISO 9001 ndi chilembo cha CE kuti muwone ngati zikutsatira malamulo aku Europe. Pa ntchito za migodi, onetsetsani kuti zikutsatira miyezo yoyenera yamakampani.

Momwe Mungasankhire Lamba Wa Kevlar Wotentha Kwambiri

1. Yesani Kufunika kwa Kutentha

Fotokozani kutentha kwanu kosalekeza komanso kutentha kwachangu nthawi yomweyo. Ngati njira yanu ikupitirira 260°C mosalekeza, ganizirani zosakaniza zosapanga dzimbiri/PBO kapena kapangidwe ka felt.

2. Unikani Zofunikira za Makina

• Kulemera kwa katundu ndi kutalika kwa conveyor
• Kuphwanyika ndi kuthekera koboola/kung'ambika
• Mphamvu yolimba komanso malire otalikira ofunikira

3. Dziwani Kapangidwe ka Lamba

• Unyolo wotseguka: Pakuwumitsa, zofunikira pa kayendedwe ka mpweya
• Lukidwe lathyathyathya: Logwiritsidwa ntchito pagalasi, chitsulo, ndi katundu wambiri
• Felt: Yogwiritsidwa ntchito kutentha kwambiri kapena njira zapadera
• Chokutidwa ndi PTFE: Chosamamatira komanso chopanda mankhwala

4. Ganizirani Mtengo Wonse wa Umwini

Ngakhale mtengo woyamba ukhoza kukhala wokwera kuposa malamba wamba, nthawi yayitali yogwirira ntchito, kuchepa kwa nthawi yogwira ntchito, komanso kugwiritsa ntchito mphamvu zochepa kwa malamba a Kevlar kumapereka phindu lalikulu kwa nthawi yayitali.

Kutsiliza: Mtengo Wabwino wa Ma Lamba a Kevlar Otentha Kwambiri

Lamba wonyamula katundu wa Kevlar wotentha kwambiri si chinthu chongowonjezera—ndi njira yabwino yogwiritsira ntchito podalirika. Mwa kupirira kutentha kwambiri, kusunga kukhazikika kwa mawonekedwe, komanso kukana kusweka, malamba a Kevlar amachepetsa nthawi yogwira ntchito, amachepetsa ndalama zokonzera, komanso amapangitsa kuti zinthu zikhale bwino m'mafakitale ovuta.

Kwa mafakitale omwe akupititsa patsogolo malire a liwiro la kupanga ndi kutentha, njira zomangira ma lamba zochokera ku Kevlar zikuyimira muyezo watsopano. Monga momwe wopanga wina adanenera, ukadaulo uwu "ukuwonetsa kusintha kwakukulu pakukwaniritsa zosowa zovuta za mizere yopanga yomwe imagwiritsa ntchito kutentha kwambiri".
