PTFE Tepi ya Abrasion-Resistant Sliding Friction: 5 Mfundo zazikuluzikulu

PTFE ndiyodziwika bwino chifukwa cha kugunda kwapakati (0.05-0.10). Koma liti Tepi ya PTFE yotentha kwambiri imagwiritsidwa ntchito potsetsereka - monga njanji zowongolera, zomangira, ma chute liners, kapena zosindikizira zotsetsereka - kukangana kokha sikokwanira. Vuto lenileni ndi kukana abrasion.

Popanda kusankha koyenera, zokutira za PTFE zimatha m'masabata, kuwonetsa gawo lapansi la fiberglass ndikupangitsa kulephera koopsa. Tepi yokhazikika yopanda ndodo sinapangidwe kuti ikhale yolumikizana ndi ma sliding.

Aokai PTFE yapanga matepi a PTFE osamva kuvala kwa mapulogalamu otsetsereka. Bukuli lili ndi mfundo zisanu zofunika kwambiri: ma metric kukana abrasion, mtundu wa zokutira, kukhazikika kwamafuta, ntchito zomatira, ndi njira zoyika.

Zizindikiro Zogwira Ntchito Kuti Mutsimikizire

1. Abrasion Resistance - The Critical Parameter

Chifukwa chiyani abrasion ya Taber ikufunika: Chophimba choyera cha PTFE chimavala mwachangu polumikizana ndi kutsetsereka. PTFE yodzazidwa (yokhala ndi carbon fiber, graphite, MoS₂, kapena glass fiber) imachepetsa kwambiri mavalidwe. Tepi yamtengo wapatali yosamva kuvala imatha kukwaniritsa <5 mg kutaya pa 1000 mizunguliro - 20-50x bwino kuposa PTFE yosadzazidwa.

Malire a PV afotokozedwa: Kuchuluka kovomerezeka kwa chinthu cholumikizana ndi Pressure (P) ndi Mayendedwe otsetsereka (V). Kupyola malirewa kumayambitsa kutha msanga, kutenthedwa, kapena kulephera kupaka. Nthawi zonse pemphani ma curve a PV kuchokera kwa ogulitsa.

Aokai PTFE imapereka magiredi osamva tepi okhala ndi kutaya kwa Taber abrasion pansi pa 10 mg/1000 mizunguliro - yotsimikiziridwa ndi kuyesa kodziyimira pawokha kwa ASTM D4060. Kupanga kwathu kodzaza ndi kaboni-fiber kumasunga μ pansi pa 0.15 ngakhale pambuyo pa 10,000 kuzungulira.

2. Coating Quality & Substrate Construction

3. Kukaniza Kutentha & Kukhazikika kwa Matenthedwe

• Kutentha kwautumiki kosalekeza kudzakwaniritsa zofunikira zogwirira ntchito (nthawi zambiri ≥260°C)

• Palibe ❖ kuyanika kwakukulu kufewetsa kapena kuthamangitsa abrasion pa kutentha kwakukulu

• Pambuyo pa ukalamba wotentha pa 250 ° C kwa maola 100, mphamvu zowonongeka ndi kuwonongeka kwa ntchito ya abrasion sizidzapitirira 20%

4. Zomatira Layer Performance (Kwa Matepi Odzimatira)

Zindikirani: Pazolowera zolemetsa zolemetsa pomwe tepiyo imakhala ndi nkhawa yanthawi zonse, ganizirani zomangira zamakina (ma rivets, zomangira) kuphatikiza zomatira.

5. Kujambula Pamwamba & Makulidwe Ofanana

• Maonekedwe apamwamba: Maonekedwe opaka pang'ono amathandiza kuti zinyalala zisamawonongeke, zimateteza kuti tinthu tating'ono ting'onoting'ono ting'onoting'ono kapena ngati pulawo iwonongeke chifukwa cha tinthu tambirimbiri.

• Kulekerera kwa makulidwe: makulidwe onse amawongoleredwa mkati mwa ± 0.02 mm kudutsa mpukutu wathunthu kuwonetsetsa kuyika kwamagetsi ndikupewa kuwonongeka kwanthawi yayitali.

Mayankho a Optimization a High-Wear Sliding Conditions

1. Yaiwisi Zinthu Zosintha

2. Mating Counterpart Matching

3. Malangizo Oyika & Zomangamanga

Kutsiliza - Mfundo Zazikulu zitatu Zosankha

Pazochitika zokhotakhota za abrasion, ikani patsogolo:

1. Kupaka kosinthidwa kwa PTFE - Carbon fiber, graphite, MoS₂, kapena galasi fiber filler imathandizira kwambiri kukana kwa Taber abrasion (chandamale <15 mg/1000 mizungu, moyenera <5 mg).

2. Gawo laling'ono lamphamvu kwambiri - Fiberglass yokhala ndi ≥200 N/cm kulimba kwamphamvu, kapena nsalu ya aramid/carbon yolemetsa kwambiri.

3. Mnzake wolamulidwa ndi roughness pamwamba - Sungani Ra 0.2-0.4 μm, gwiritsani ntchito chitsulo chosapanga dzimbiri kapena chrome yolimba.

Zowonjezera zofunika:

• Funsani data ya Taber abrasion ndi malire a PV kuchokera kwa ogulitsa.

• Ikani ndi chitetezo cham'mphepete (mizere yokhotakhota, kuyika ma groove, magawo okwerera a chamfered).

• Pakuti katundu wolemetsa mosalekeza kutsetsereka, kuphatikiza zomatira ndi mawotchi kumangiriza.

• Mapangidwe osinthira ma modular ngati kuli kotheka.

Mwachidule, kusankha tepi ya PTFE yotentha kwambiri ya abrasive sliding friction applications imafuna kupitilira zomwe sizili zomata komanso zotentha. Yang'anani kwambiri pakutaya kwa Taber abrasion (<15 mg/1000 cycle), zokutira zosinthidwa zodzaza, mphamvu yapansi panthaka (≥200 N/cm), ndi kukhwinyata pamwamba (Ra 0.2-0.4 μm). Kutetezedwa koyenera m'mphepete, kulumikizana kwathunthu, ndi mapangidwe amtundu wa modular amakulitsa moyo wautumiki kwambiri.

Pewani tepi ya PTFE yosadzazidwa kuti mulumikizane ndi kutsetsereka - idzawonongeka mwachangu. M'malo mwake, tchulani magiredi osamva kuvala okhala ndi data yotsimikizika ya abrasion.

Mukufuna tepi ya PTFE yosamva kuvala pa pulogalamu yanu yotsetsereka? Aokai PTFE imapereka magiredi a carbon-fiber, graphite, ndi MoS₂-odzaza ndi Taber abrasion loss pansi pa 10 mg/1000 cycle. Lumikizanani nafe ndi kukakamizidwa kwanu, kuthamanga, ndi zinthu zina zofananira kuti tikulimbikitseni.

Zomwe Zaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Kuti mumve mwatsatanetsatane, kufunsira ntchito, ndi mayankho makonda omwe akuphimba PTFE nsalu yotentha kwambiri, tepi yomatira ya PTFE, lamba wa PTFE mauna, lamba wosasunthika, lamba wa mbali imodzi ya PTFE, lamba wosamva kutentha ndi nsalu yotentha kwambiri ya fiberglass , chonde titumizireni:

• Bambo Guo: +86 18944819998

• Bambo Liu: + 86 13705266308

Timatsatira ukatswiri ndi kukhulupirika kuti tipereke mayankho amtundu umodzi ndi ntchito yosamalira pambuyo pogulitsa.
