PTFE Igishushanyo cya Abrasion-Kurwanya Kunyerera Kunyerera: 5 Ibyingenzi

Reba: 0 Umwanditsi: Muhinduzi wurubuga Gutangaza Igihe: 2026-06-02 Inkomoko: Urubuga

PTFE izwiho kuba coefficient nkeya (0.05-0.10). Ariko ryari PTFE yubushyuhe bwo hejuru ikoreshwa mugushushanya porogaramu - nko kuyobora inzira, kwambara imirongo, imirongo ya chute, cyangwa kashe yo kunyerera - guterana byonyine ntibihagije. Ikibazo nyacyo ni ukurwanya abrasion.

Hatabayeho guhitamo neza, igifuniko cya PTFE cyambara mugihe cyibyumweru, kigaragaza substrate ya fiberglass kandi bigatera kunanirwa gukabije. Ikaseti isanzwe idafite inkoni ntabwo yagenewe guhuza imbaraga.

Aokai PTFE yashyizeho kaseti ya PTFE idashobora kwambara kugirango isabe kunyerera. Aka gatabo gakubiyemo ibintu bitanu byingenzi: ibipimo byo kurwanya abrasion, ibipimo byiza, ubushyuhe bwumuriro, imikorere ifatika, hamwe nubuhanga bwo kwishyiriraho.

Ibipimo Byibanze Byerekana Kugenzura

1. Kurwanya Abrasion - Ikintu Cyingenzi

Uburyo bwo Kwipimisha	Bisanzwe	Agaciro gasanzwe (Standard PTFE)	Intego yo Kwambara-Kurwanya
Gutakaza Taber Abrasion (ASTM D4060, CS-17 ibiziga, umutwaro 1000g)	mg / 1000 inzinguzingo	Amajana ya mg	<15 mg (premium: <5 mg)
Coefficient de Dynamic ya Friction	μ	0.05-0.10 mu ntangiriro	Ihamye 0.05-0.15 hejuru yubuzima
Imipaka ya PV (Umuvuduko × Umuvuduko)	Pa · m / s cyangwa psi · fpm	Biratandukanye ukurikije formulaire	Kubona kubitanga

Impamvu gukuramo Taber bifite akamaro: Igifuniko cyiza cya PTFE cyambara byihuse munsi yo kunyerera. Huzuye PTFE (hamwe na fibre karubone, grafite, MoS₂, cyangwa fibre fibre) igabanya cyane igipimo cyo kwambara. Kaseti irwanya kwambara irashobora kugera kuri <5 mg igihombo kuri 1000 cycle - 20-50x nziza kuruta PTFE ituzuye.

PV ntarengwa yasobanuwe: Igicuruzwa ntarengwa cyemewe cyo guhuza Umuvuduko (P) no kunyerera umuvuduko (V). Kurenga iyi mipaka bitera kwambara vuba, gushyuha, cyangwa gutsindwa. Buri gihe saba PV umurongo utanga isoko.

Aokai PTFE itanga amanota adashobora kwambara hamwe no gutakaza Taber abrasion munsi ya 10 mg / 1000 cycle - byemejwe nigeragezwa ryigenga rya ASTM D4060. Carbone-fibre yuzuye yuzuye ikomeza μ munsi ya 0.15 na nyuma yizunguruka 10,000.

2. Gutwikira Ubwiza & Substrate Ubwubatsi

Parameter	Icyifuzo	Kubera iki
Ubunini bwububiko (ubuso bukora)	≥0.05 mm (0.08-0.15 mm yo kwambara cyane)	Gupfundikanya cyane bitanga ubuzima burebure
Ubwoko bwo gutwikira	Yujujwe PTFE (karubone, grafite, MoS₂, fibre y'ibirahure)	Kurwanya kure cyane abrasion birwanya v
Uburinganire	Nta pinholes, yacumuye rwose	Irinda guhura hakiri kare ya fiberglass
Imyenda shingiro imbaraga	≥200 N / cm	Irwanya kurambura munsi yo gutemagura
Ubwoko bw'ububoshyi	Imbaraga nyinshi cyane cyangwa satine	Umwenda wa Aramide kumitwaro ikabije

3. Ubushyuhe bwo Kurwanya & Ubushyuhe Bwinshi

Ubushyuhe bwa serivisi bukomeza buzuza ibisabwa (mubisanzwe ≥260 ° C)
Nta gutwikisha gukabije koroshya cyangwa kwihuta gukuramo ubushyuhe bwinshi
Nyuma yo gusaza k'ubushyuhe kuri 250 ° C mu masaha 100, imbaraga zingana no kwangirika kwimikorere ntibishobora kurenga 20%

4. Imikorere ya Layeri Yerekana (Kuri Kanda-Kwifata)

Ubwoko bufatika	Kurwanya Ubushyuhe	Kurwanya Kurwanya	Birakwiriye kunyerera
Silicone PSA	60260 ° C.	Nibyiza hamwe no guhuza neza	Guhitamo inzira nyamukuru
Acrylic PSA	≤150 ° C.	Abakene munsi yubushyuhe	Ntabwo bisabwa kunyerera cyane
Primer + silicone	60260 ° C.	Cyiza	Kubutaka-buke-imbaraga substrate (urugero, ibyuma bidafite ingese)

Icyitonderwa: Kubintu biremereye cyane byo kunyerera aho kaseti ikomeje guhangayikishwa no kogosha, tekereza ku gufunga imashini (imirongo, imirongo ifata) wongeyeho gufatira hamwe.

5. Ubuso bwubuso & Ubunini bwuburinganire

Ubuso bwubuso: Imyenda idahwitse ifasha kugumana imyanda yambara neza, irinda imitwe ya coefficient cyangwa imyenda yo guhinga yo guhinga iterwa nuduce duto twinshi.
Kwihanganira kubyimbye: Ubunini bwuzuye bugenzurwa muri mm 0,02 mm hejuru yumuzingo wuzuye kugirango ushireho flush kandi wirinde gusenyuka hakiri kare.

Umwanzuro - Amahame atatu yo gutoranya

Kuri abrasion-yibanze kunyerera, shyira imbere:

Kuzuza ibifuniko bya PTFE - Fibre ya karubone, grafite, MoS₂, cyangwa fibre fibre yuzuza cyane uburyo bwo kurwanya Taber abrasion (intego <15 mg / 1000 cycle, nibyiza <5 mg).
Imbaraga zikomeye substrate - Fiberglass ifite ≥200 N / cm imbaraga zingana, cyangwa imyenda ya aramid / karubone kumitwaro ikabije.
Igenzurwa na mugenzi wawe ugereranije - Komeza Ra 0.2-0.4 μ m, koresha ibyuma bitagira umwanda cyangwa chrome ikomeye.

Ibisabwa by'inyongera:

Saba amakuru yo gukuramo Taber hamwe na PV imipaka kubatanga isoko.
Shyiramo kurinda inkingi (imirongo ifatanye, gushiramo ibiti, ibice byo gushyingiranwa).
Kubiremereye-biremereye bikomeza kunyerera, komatanya ibifatika hamwe no gufunga imashini.
Igishushanyo cyo gusimbuza modular aho bishoboka.

Muncamake, guhitamo PTFE yubushyuhe bwo hejuru bwa kaseti ya abrasive kunyerera ya porogaramu isaba kurenga ibisanzwe bitari inkoni hamwe nubushyuhe bwumuriro. Wibande ku gutakaza Taber abrasion (<15 mg / 1000 cycle), yuzuza igifuniko cyahinduwe, substrate imbaraga zingana (≥200 N / cm), hamwe no guhuza ubutumburuke (Ra 0.2-0.4 μm). Kurinda impande zose, guhuza byuzuye, hamwe nubushakashatsi bwongerewe ubuzima bwa serivisi kuburyo butangaje.

Irinde kaseti ya PTFE ituzuye kugirango uhuze kunyerera - bizambara vuba. Ahubwo, vuga amanota adashobora kwambara hamwe namakuru yemewe yo gukuramo.

Ukeneye kaseti idashobora kwangirika ya PTFE kugirango usabe kunyerera? Aokai PTFE itanga karuboni-fibre, grafite, na MoS₂ yuzuye amanota hamwe no gutakaza Taber abrasion munsi ya 10 mg / 1000. Twandikire hamwe nigitutu cyawe, umuvuduko, hamwe nibindi bikoresho kugirango tugusabe.
