Kayan rufe bawul muhimmin ɓangare ne na rufe bawul. Menene kayan rufe bawul? Mun san cewa an raba kayan rufe bawul zuwa rukuni biyu: ƙarfe da wanda ba ƙarfe ba. Ga taƙaitaccen bayani game da yanayin amfani da kayan rufewa daban-daban, da kuma nau'ikan bawul ɗin da aka saba amfani da su.
1. Roba mai roba
Cikakken Properties na roba roba irin su juriya mai, juriya da zafin jiki da kuma lalata juriya sun fi na halitta roba. Kullum, da amfani da zafin jiki na roba roba ne t≤150 ℃, da kuma zafin jiki na halitta roba ne t≤60 ℃. Rubber da ake amfani da su hatimi duniya bawuloli,roba zaune gate bawul, diaphragm bawuloli,rbawul ɗin malam buɗe ido na ubber, rubber zaune shan ruwa duba bawul (duba bawuloli), tsunkule bawuloli da sauran bawuloli tare da maras muhimmanci matsa lamba PN≤1MPa.
2. Nailan
Naylon yana da halaye na ƙananan juzu'i mai kyau da juriya mai kyau. Ana amfani da nailan galibi don bawul ɗin ball da bawul ɗin duniya tare da zafin jiki t≤90 ℃ da matsa lamba PN≤32MPa.
3. PTFE
Ana amfani da PTFE galibi don bawuloli na duniya,bakin kofa, ball bawuloli, da dai sauransu tare da zazzabi t≤232 ℃ da maras muhimmanci matsa lamba PN≤6.4MPa.
4. Karfe
Ana amfani da baƙin ƙarfe donbakin kofa, bawul ɗin duniya, bawul ɗin toshewa, da sauransu don zafin jiki t≤100℃, matsin lamba na musamman PN≤1.6MPa, iskar gas da mai.
5. Babbitt gami
Babbitt gami da ake amfani da ammonia globe bawul tare da zazzabi t-70 ~ 150 ℃ da maras muhimmanci matsa lamba PN≤2.5MPa.
6. Copper gami
Abubuwan gama gari don gami da jan ƙarfe sune 6-6-3 tin tagulla da tagulla na manganese 58-2-2. Copper gami yana da kyau lalacewa juriya kuma ya dace da ruwa da tururi tare da zazzabi t≤200 ℃ da maras muhimmanci matsa lamba PN≤1.6MPa. Ana yawan amfani dashi a cikinbakin kofa, bawuloli na duniya,duba bawuloli, bawuloli na toshewa, da sauransu.
7. Chrome bakin karfe
Karfe mai bakin ƙarfe mai siffar chromium da aka fi amfani da shi shine 2Cr13 da 3Cr13, waɗanda aka kashe su kuma aka daidaita su, kuma suna da juriya mai kyau ga tsatsa. Sau da yawa ana amfani da shi a cikin bawuloli na kafofin watsa labarai kamar ruwa, tururi da man fetur waɗanda zafinsu ya kai ≤450℃ da matsin lamba na musamman PN≤32MPa.
8. Chromium-nickel-titanium bakin karfe
Matsayin da aka saba amfani da shi na chromium-nickel-titanium bakin karfe shine 1Cr18Ni9ti, wanda ke da juriya mai kyau na lalata, juriya na yashwa da juriya mai zafi. Ya dace da tururi, nitric acid da sauran kafofin watsa labarai tare da zazzabi t≤600 ℃ da maras muhimmanci matsa lamba PN≤6.4MPa, amfani da globe bawul, ball bawul, da dai sauransu.
9. Nitrided karfe
Matsayin da aka saba amfani da shi na nitrided karfe shine 38CrMoAlA, wanda ke da juriya mai kyau da juriya bayan carburizing jiyya. Yawanci amfani da wutar lantarki ƙofar bawul tare da zazzabi t≤540 ℃ da maras muhimmanci matsa lamba PN≤10MPa.
10. Basarake
Boronizing kai tsaye yana aiwatar da saman rufewa daga kayan jikin bawul ko jikin diski, sannan kuma aiwatar da jiyya ta fuskar boronizing, saman rufewa yana da juriya mai kyau. Ana amfani da bawul ɗin busa wutar lantarki.
