Phakathi kwezinto ezichaphazela umgangatho we-element yokufudumeza enyibilikayo ngombane, umgangatho wezinto ezisetyenziswayo sisizathu esibalulekileyo. Ukukhetha ngokufanelekileyo izinto eziluhlaza zetyhubhu yokufudumeza enyibilikayo kukuqinisekisa umgangatho we-heater enyibilikayo.
1, umgaqo wokukhetha umbhobho: ukumelana nobushushu, ukumelana nokugqwala.
Kwimibhobho enobushushu obuphantsi, kusetyenziswa imibhobho ye-BUNDY, i-aluminium, i-copper, kwaye imibhobho enobushushu obuphezulu kusetyenziswa imibhobho yentsimbi engatyiwayo kunye nemibhobho ye-Ingle. Ityhubhu yokufudumala ye-Ingle 800 ingasetyenziswa kwimeko yomgangatho ophantsi wamanzi, ityhubhu yokufudumeza yombane ye-Ingle 840 ingasetyenziswa kwimeko yokusebenza enobushushu obuphezulu, inokumelana okuhle nokubola, kwaye inokumelana okuhle nokugqwala.
2, ukukhethwa kwentambo yokumelana
Izixhobo zentambo yokumelana ezisetyenziswa kakhulu kwi-element yombane yokunyibilikisa iqhwa yintambo yokumelana ye-Fe-Cr-Al kunye ne-Cr20Ni80. Umahluko ophambili phakathi kweentambo ezimbini zokumelana kukuba iqondo lokunyibilika le-0Cr25Al5 liphezulu kunele-Cr20Ni80, kodwa kumaqondo obushushu aphezulu, i-0Cr25Al5 kulula ukuyinyibilikisa, kwaye i-Cr20Ni80 inokugcina ukusebenza okuzinzileyo kumaqondo obushushu aphezulu. Ke ngoko, intambo yokumelana esetyenziswa kumaqondo obushushu aphezulu ngokubanzi yi-Cr20Ni80.
3, ukukhethwa komgubo weMgO
Umgubo weMgO uphakathi kwentambo yokumelana nodonga lwetyhubhu kwaye usetyenziselwa ukufudumala phakathi kwentambo yokumelana nodonga lwetyhubhu. Kwangaxeshanye, umgubo weMgO unomoya ofudumeleyo. Nangona kunjalo, umgubo weMgO uneempawu ezinamandla ze-hygroscopic, ngoko ke kufuneka uphathwe ngokumelana nokufuma (umgubo weMgO oguquliweyo okanye uvalwe ngombhobho wobushushu wombane) xa usetyenziswa.
Umgubo weMgO ungahlulwa ube ngumgubo obushushu obuphantsi kunye nomgubo obushushu obuphezulu ngokwezinga lobushushu elisetyenzisiweyo. Umgubo obushushu obuphantsi ungasetyenziswa kuphela ngaphantsi kwama-400 ° C, umgubo weMgO oguquliweyo ngokubanzi.
Umgubo we-MgO osetyenziswa kumbhobho wobushushu wombane wenziwe ngamasuntswana omgubo we-MgO obukhulu obahlukeneyo ngokuhambelana nomlinganiselo othile (umlinganiselo we-mesh).
4, ukhetho lwezinto zokutywina
Indima yezinto zokutywina kukuthintela umswakama womoya ukuba ungangeni kumgubo we-MgO ngomlomo wombhobho, ukuze umgubo we-MgO ube manzi, ukusebenza kobushushu kunciphe, kwaye umbhobho wobushushu wombane uvuza kwaye ungasebenzi. Umgubo we-magnesia oguquliweyo awunakuvalwa.
Izinto eziphambili ezisetyenziselwa ukuvala ityhubhu yokufudumeza yombane (engangeni kumswakama) yiglasi, i-epoxy resin, i-silicone oil njalo njalo. Kwipayipi yobushushu yombane evalwe nge-silicone oil, emva kokufudumeza, i-silicone oil emlonyeni wombhobho iya kutshabalala bubushushu, kwaye ubushushu bombhobho wobushushu bombane buya kuncipha. Ukumelana nobushushu bezinto ze-epoxy resin akuphezulu, kwaye ayinakusetyenziswa kwiityhubhu zombane ezinobushushu obuphezulu ezifana ne-barbecue kunye ne-microwave oven enobushushu obuphezulu emlonyeni wombhobho. Iglasi inokumelana nobushushu obuphezulu, kodwa ixabiso liphezulu, kwaye isetyenziswa ngakumbi ukuvala iityhubhu ezinobushushu obuphezulu.
Ukongeza, kuya kubakho iityhubhu ze-silicone, imikhono ye-silicone, ii-porcelain beads, ii-insulators zeplastiki kunye nezinye iindawo emlonyeni wombhobho, ikakhulu ukwandisa umsantsa wombane kunye nomgama wokuqhekeka phakathi kwentonga yentsimbi kunye nodonga lwesinyithi lomlomo wombhobho. Irabha ye-silicone inokudlala indima yokuzalisa kunye nokubopha.
