Dangane da rabe-raben FNLONGO na rufin feshin thermal, ana iya raba sutura zuwa:
1. Sanya sutura mai juriya
Ya haɗa da m lalacewa resistant, saman kasala lalacewa juriya da yashwa resistant shafi.A wasu lokuta, akwai nau'ikan nau'ikan sutura masu juriya iri biyu: ƙananan zafin jiki (<538 ℃) sa suturar da ba ta da ƙarfi da zafin jiki mai ƙarfi (538 ~ 843 ℃) sa suturar juriya.
2. Heat resistant da hadawan abu da iskar shaka resistant shafi
A shafi ya hada da coatings amfani a high-zazzabi matakai (ciki har da hadawan abu da iskar shaka yanayi, iskar gas, yashwa da thermal shãmaki sama da 843 ℃) da narkakkar tafiyar matakai (ciki har da zub da jini tutiya, narkakkar aluminum, narkakkar baƙin ƙarfe da karfe, da narkakkar jan karfe).
3. Anti atmospheric da immersion lalata coatings
Lalacewar yanayi ya haɗa da lalata da yanayin masana'antu, yanayin gishiri da yanayin filin;Lalacewar nutsewa ta haɗa da lalata ta hanyar shan ruwa mai daɗi, rashin shan ruwa mai daɗi, ruwan zafi, ruwan gishiri, sunadarai da sarrafa abinci.
4. Gudanarwa da juriya shafi
Ana amfani da wannan shafi don ƙaddamarwa, juriya da kariya.
5. Mayar da shafi mai girma
Wannan shafi da ake amfani da baƙin ƙarfe tushen (machinable da grindable carbon karfe da lalata resistant karfe) da kuma non-ferrous karfe (nickel, cobalt, jan karfe, aluminum, titanium da gami) kayayyakin.
6. Gap kula da shafi don kayan aikin injiniya
Wannan shafi yana da niƙa.
7. Chemical resistant shafi
Lalacewar sinadarai ya haɗa da lalata nau'ikan acid, alkalis, salts, abubuwa daban-daban na inorganic da kafofin watsa labarai na sinadarai daban-daban.
Daga cikin sama shafi ayyuka, lalacewa-resistant shafi, zafi resistant da hadawan abu da iskar shaka resistant shafi da sinadaran lalata resistant shafi suna a hankali da alaka da karfe masana'antu samar.
Misali, muPC da samfuran PMMAsau da yawa amfani da shafi.
Yawancin samfuran PC da PMMA suna da buƙatun saman ƙasa, waɗanda gabaɗaya buƙatun gani ne.Sabili da haka, dole ne a rufe saman samfurin don hana fashewa.
