Kodi ndi njira ziti zowunikira zomwe zimatsutsana ndi kumamatira komanso kuyeretsa kosavuta kwa nsalu ya PTFE-yakutidwa ndi fiberglass pokhudzana ndi madontho amafuta ndi fumbi?

1. Contact Angle ndi Surface Energy Testing (Wettability Basics)

 

- Static Contact angle: Amayezedwa pogwiritsa ntchito madzi ndi diiodomethane (kapena hexadecane) mosiyana. Nthawi yolumikizana ndi madzi imakhala yopitilira 110 °. Kulumikizana kwakukulu kwamafuta kumawonetsa kukana kwambiri pakuwonongeka kwamafuta ndi kumamatira.

- Ngolo Yogudubuzika/Yotsetsereka: Kokona komwe dontho la voliyumu inayake limayamba kusuntha kuchoka pamalo opendekeka pang'onopang'ono. Kang'ono kakang'ono kakugudubuza kamasonyeza zinthu zabwino zokana kumatira komanso zotsuka mosavuta, zomwe ndizofunikira kwambiri pakuyesa madontho amafuta.

- Kuwerengera Kwamphamvu Kwaulere Pamwamba: Zida za polar ndi zobalalika zimawerengedwa pogwiritsa ntchito njira monga Owens-Wendt. Kutsika kwamphamvu kwamphamvu (PTFE yamtengo wapatali ndi pafupifupi 18–20 mN/m), m'pamenenso zimakhala zovuta kuti zowononga zolimba ndi zakumwa zinyowetse ndikufalikira.

 

2. Kuwunika Kwamakina kwa Zinthu Zotsutsana ndi Kumamatira (Peel Force/Adhesion Force)

 

- Standard Pressure-Sensitive Tape Peel Test: Tepi yodziwika yodziwika bwino (monga 3M 810 kapena tepi yodziwikiratu) imakanikizidwa pa tepi ya PTFE pogwiritsa ntchito chogudubuza chokhazikika. Pambuyo posiyidwa kuti muyime kwa nthawi yoikika, kuyesa kwa peel ya 180 ° kumachitidwa ndi makina oyesera (onani GB / T 2792). Kutsika kwa mphamvu ya peel, kumapangitsanso katundu wotsutsa-kumata, ndi mtengo wabwino pansi pa 0.1 N/25 mm.

- Specific Medium Adhesion Test: Zinthu zomatira zomwe zimagwiritsidwa ntchito, monga phula, zomatira zodzimatira, kapena zomatira zosungunuka kutentha, zimagwiritsidwa ntchito kuyeza mphamvu yofunikira kuzivunda.

 

3. Mayesero Oyerekeza Otsutsana ndi Mafuta ndi Kuyeretsa Kosavuta

 

- Njira Yotsatsira Madontho a Mafuta: Mafuta a injini, mafuta ophikira, kapena mafuta opangira amapaka pa chitsanzo chopendekeka pakona inayake. Utali wotsetsereka wa banga lamafuta kapena kuchuluka kwa malo otsalira pamwamba amayezedwa.

- Kugwiritsa Ntchito Mwachangu Kupukuta:

    - Dothi lochita kupanga (losakanizidwa ndi mpweya wakuda, mafuta, ndi oleic acid) limagwiritsidwa ntchito mofanana ndikuuma. Nsalu yopanda lint yonyowa ndi madzi ndi chosalowerera ndale imagwiritsidwa ntchito kupukuta mmbuyo ndi mtsogolo kwa chiwerengero chokhazikika cha maulendo pansi pa katundu woikidwa.

    - Opanga nsalu za PTFE-zokutidwa ndi fiberglass ku Jiangsu nthawi zambiri amagwiritsa ntchito mita yosiyanitsa mitundu kuti ayeze kusiyana kwa mtundu ΔE asanayambe kapena kupukuta, kapena kuwerengera kuyeretsa bwino pogwiritsa ntchito nthaka yotsalira (njira ya gravimetric). ΔE yaying'ono komanso kulemera kotsalira kotsalira kumasonyeza bwino kuyeretsa kosavuta. Chiwopsezo cha kuchira kwa ngodya yolumikizana pamtunda woyeretsedwa nawonso ukhoza kuyesedwa.

- Kuyesa Kwachangu Kwambiri Ndi Cholemba Mafuta: Cholembera chamafuta chimagwiritsidwa ntchito kujambula mizere pamwamba. Yang'anani ngati inkiyo ikucheperachepera kukhala madontho osapitirira kapena kufalikira mosalekeza, ndiyeno pukutani ndi nsalu youma kuti muwone ngati ikuchotsedwa mosavuta. Kuchulukitsidwa kotchulidwa ndi kuchotsedwa kosavuta kumawonetsa zinthu zabwino zotsutsana ndi zonyansa komanso zosavuta kuyeretsa.

 

4. Kuyesa kwa Anti-Fumbi ndi Anti-Particle Adhesion Testing

 

- Njira Yokhazikitsira Fumbi: Fumbi loyezetsa (mwachitsanzo, ISO 12103-1 A2 fumbi labwino) limaloledwa kukhazikika mwachilengedwe pazitsanzo za 45 ° mkati mwa chipinda chotsekedwa. Pambuyo pogogoda pang'onopang'ono kapena kuwomba ndi mpweya wocheperako, malo otsalira afumbi amayezedwa pogwiritsa ntchito kusanthula kwazithunzi kapena njira za gravimetric.

- Kuchotsa Fumbi ndi Njira Yoyendetsera Mphepete: Fumbi lodziwika bwino limawazidwa mofanana pa chitsanzo chopingasa. Kuthamanga kwa mtsinje wa nayitrogeni kumachulukitsidwa pang'onopang'ono, ndipo kuthamanga kwa mpweya wocheperako komwe kumafunikira kuti kuphulike fumbi kumalembedwa. Kutsika kwa liwiro, kumakhala bwinoko anti-fust adhesion properties.

- Kuwunika kwa Electrostatic Adsorption Effects: Popeza kuti kutulutsa fumbi nthawi zambiri kumachulukitsidwa ndi magetsi osasunthika, mphamvu yolimbana ndi mphamvu yamagetsi ndi nthawi yowola ya electrostatic iyeneranso kuyesedwa kuti isiyanitse ngati zotsatira zake zimachitika chifukwa cha anti-sticking kapena electrostatic adsorption.

 

5. Kuthandizira Kuwunika Kukhazikika

 

- Pambuyo pa ukalamba wotentha kwambiri (mwachitsanzo, pa 260 ° C kapena 300 ° C) kapena kukangana / kuvala (Taber abrasion), njira yomwe tatchula pamwambapa, mphamvu ya peel, ndi kuyesa koyeretsa kumabwerezedwa kuti zitsimikizire kuti ntchito sizikuwonongeka kwambiri pakagwiritsidwe ntchito nthawi yayitali.
