Menene hanyoyin kimantawa don ƙin ɗorawa da sauƙin tsaftacewa na masana'anta na fiberglass mai rufi na PTFE dangane da tabon mai da ƙura?

1. Angle da Surface Energy Testing (Wettability Basics)

 

- Matsayin Tuntuɓi A tsaye: Ana auna ta amfani da ruwa da diodomethane (ko hexadecane) daban. Matsakaicin lamba ruwan yana yawanci sama da 110°. Babban kusurwar tuntuɓar mai yana nuna ƙarfin juriya ga lalata mai da mannewa.

- Mirgina/Sliding Angle: kusurwar da ɗigo na takamaiman ƙara ya fara zamewa daga ƙasa mai karkata a hankali. Karamin kusurwar mirgina yana nuna ingantattun kaddarorin anti-stick da sauƙin tsaftacewa, wanda ke da mahimmanci musamman don gwajin tabo mai.

- Lissafin Ƙarfafa Makamashi Kyauta: Ana ƙididdige polar da abubuwan tarwatsawa ta amfani da hanyoyi kamar Owens-Wendt. Ƙarƙashin makamashin sararin samaniya (ƙimar PTFE ta kusan 18-20 mN/m), zai fi wahala ga ƙaƙƙarfan gurɓata da ruwa don jika da yadawa.

 

2. Ƙimar Injini na Kayayyakin Anti-Sticking (Ƙarfin Peel/Adhesion Force)

 

- Gwajin kwasfa na matsi-matsakaici na tef: ƙayyadadden tef ɗin daidaitaccen tef (misali, 3M 810 ko keɓaɓɓen tef ɗin matsi) ana danna saman tef ɗin PTFE ta amfani da daidaitaccen abin nadi. Bayan an bar shi don tsayawa don ƙayyadaddun lokaci, ana yin gwajin kwasfa 180° tare da na'urar gwaji mai ƙarfi (koma zuwa GB/T 2792). Ƙarƙashin ƙarfin kwasfa, ƙaƙƙarfan kayan anti-stick, tare da madaidaicin ƙimar ƙasa 0.1 N/25 mm.

- Specific Medium Adhesion Test: Ana amfani da abubuwa masu mannewa waɗanda a zahiri ake cin karo da su a cikin amfani, kamar kwalta, tambarin manne kai, ko narke mai zafi, ana amfani da su don auna ƙarfin da ake buƙata don kwaɓe su daga saman.

 

3. Gwaje-gwajen Kwaikwayi don Juriya na Mai da Sauƙaƙe Tsabta

 

- Hanyar Sliding/Sauran Tabon Mai: Adadin adadin man inji, mai dafa abinci, ko man shafawa na wucin gadi ana shafa akan samfurin da aka karkata a wani kusurwa. Ana auna tsayin zamewar tabon mai ko yawan ragowar yanki a saman.

- Ingantaccen Tsabtace Yawan Shafa:

    - daidaitaccen ƙasa na wucin gadi (gaɗin baƙin carbon, maiko, da oleic acid) ana shafa daidai gwargwado kuma a bushe. Ana amfani da kyalle mara lint wanda aka jika da ruwa da kuma abin wanke-wanke mai tsaka-tsaki don goge baya da gaba don ƙayyadaddun adadin zagayowar ƙarƙashin nauyin saiti.

    - Masu kera masana'anta na fiberglass mai rufi na PTFE a cikin Jiangsu yawanci suna amfani da mitar bambancin launi don auna bambancin launi ΔE kafin da bayan shafa, ko ƙididdige ingancin tsaftacewa ta ragowar ƙasa (hanyar gravimetric). Ƙananan ΔE da ƙananan nauyin ragowar suna nuna kyakkyawan aikin tsaftacewa mai sauƙi. Hakanan za'a iya auna ƙimar dawo da kusurwar lamba akan farfajiya mai tsabta.

- Gwajin inganci mai sauri tare da Alamar mai: Ana amfani da alamar mai don zana layi akan saman. Duba ko tawada yana raguwa zuwa ɗigon ɗigon ruwa mai katsewa ko kuma yana bazuwa gabaɗaya, sannan a shafa da bushe bushe don ganin ko an cire shi cikin sauƙi. Ƙunƙarar da aka bayyana da kuma cirewa cikin sauƙi yana nuna kyawawan kaddarorin hana lalata da sauƙin tsaftacewa.

 

4. Anti-Kura da Anti-Barbashi Manne Gwajin

 

Hanyar Gyaran Kura: Tsarin gwajin ƙura (misali ISO 12103-1 A2 kyakkyawan ƙura) an ba da izinin daidaitawa ta dabi'a a tsaye ko 45-ƙirar samfurin saman a cikin rufaffiyar ɗakin. Bayan tausa a hankali ko busa tare da ƙarancin iskar gas, ana auna sauran ƙurar ƙura ta amfani da nazarin hoto ko hanyoyin gravimetric.

- Cire ƙura ta Hanyar iska: Sanannen adadin ƙurar ana yayyafa shi daidai a kan samfurin kwance. Matsakaicin kwararar rafin nitrogen yana ƙaruwa a hankali, kuma ana yin rikodin mafi ƙarancin saurin iskar da ake buƙata don busa ƙurar gaba ɗaya. Ƙananan saurin gudu, mafi kyawun kayan mannewar ƙura.

- Ƙimar Tasirin Adsorption na Electrostatic: Tun da ƙura adsorption sau da yawa yana ƙara tsanantawa ta hanyar wutar lantarki mai mahimmanci, kuma ya kamata a gwada tsayayyar yanayin da kuma lokacin lalata electrostatic don bambance ko tasirin ya kasance saboda maganin anti-stick ko electrostatic adsorption.

 

5. Taimakawa Ƙimar Dorewa

 

- Bayan tsufa mai zafi (misali, a 260 ° C ko 300 ° C) ko gogayya / sawa (Taber abrasion), kusurwar lamba da aka ambata a sama, ƙarfin kwasfa, da gwajin ingancin tsaftacewa ana maimaita su don tabbatar da cewa aikin baya raguwa sosai yayin amfani da dogon lokaci.
