Ukukhetha ikhompawundi yokutywina ekunene kubalulekile kwimpumelelo yeprojekthi yokuvuza okuvuzayo kwi-intanethi, kuba iikhompawundi ezahlukeneyo ziyilelwe ukuhlangabezana neemfuno ezahlukeneyo zeemeko zokusebenza. Izinto ezintathu eziguquguqukayo zidla ngokuqwalaselwa xa kuvavanywa iimeko zokusebenza: ubushushu benkqubo evuzayo, uxinzelelo lwenkqubo kunye nendawo evuzayo. Ngokusekwe kwiminyaka yamava omsebenzi kunye neelebhu kunye nabasebenzi abasebenza kwindawo, siphuhlise olu luhlu lulandelayo lwekhompawundi yokutywina:
Isitywina seThermosetting
Olu luhlu lokutywina ikhompawundi lunokusebenza kakuhle kubushushu obuphakathi obuvuzayo. Iya komelela ngokukhawuleza xa itofwe kumngxuma wokutywina. Ke kulungile ukusetyenziselwa izixhobo ezincinci ezivuzayo. Ixesha le-thermosetting lixhomekeke kubushushu benkqubo, sinokuhlengahlengisa ifomula yokuphucula okanye ukulibazisa ixesha le-thermosetting ngokusekelwe kwisicelo sabaxhasi.
Uphawu: Ukuchasana okubanzi okuphakathi kunye nokuguquguquka okulungileyo kunye nokunyanzeliswa, okusebenzayo kwiiflange, iipayipi, iibhoyili, i-heater exchangers njl. phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu. Ukusetyenziswa kwevalvu evuzayo akukhuthazwa.
Uluhlu lobushushu: 100℃~400℃ (212℉～752℉) 20C (68℉)
UgcinoIimeko:phantsi kobushushu begumbi, ngaphantsi kwe-20℃
Ubomi bobuqu: isiqingatha seminyaka
I-PTFE esekelwe, Ukuzalisa i-Sealant
Olu hlobo lwekhompawundi yokutywina yeyesixhobo sokutywina esinganyangekiyo esisetyenziselwa ukuvuza kobushushu obuphantsi kunye nokuvuza okuphakathi kwemichiza. Yenziwe nge-PTFE imathiriyeli ekrwada ene-fluidity elungileyo phantsi kobushushu obuphantsi kwaye inokuthwala i-corrosion eyomeleleyo, ityhefu kunye nendawo evuzayo eyingozi.
Uphawu: Ilungile kwimichiza eyomeleleyo, i-oyile kunye nokumelana nolwelo, kusebenza kuzo zonke iintlobo zokuvuza kwiflange, umbhobho kunye nevalve.
Uluhlu lobushushu: -100℃~260℃ (-212℉～500℉)
Iimeko zokuGcina: ubushushu begumbi
Ubomi bobuqu: iminyaka eyi-2
I-Thermal-expansion Sealant
Olu luhlu lokutywina ikhompawundi yenzelwe ukujongana nokuvuza kobushushu obuphezulu. Ngokwesiqhelo, emva kokutofa, inkqubo yokutofa kwakhona iyafuneka ukuze kuthintelwe ukuvuza kwakhona, kuba ukutywinwa koxinzelelo lwecango kuya kutshintsha ukuba uxinzelelo lwejoyi lokutofa ngalinye lwahlukile. Kodwa ukuba i-sealant eyandisiweyo isetyenzisiwe, ngakumbi ukuvuza okuncinci, akukho mfuneko yokutofa kwakhona kuba ukwandisa i-sealant kuya kulinganisa ukutywina uxinzelelo lwecango ngokuzenzekelayo.
Uphawu: Ukwandiswa kwe-Thermal, ukunganyangi, ukunyaniseka okugqwesileyo phantsi kobushushu obuphezulu, obusebenzayo kwi-flange, umbhobho, iivalve, iibhokisi zokugxusha.
Uluhlu lobushushu: 100℃~600℃ (212℉～1112℉)
Iimeko zokuGcina: ubushushu begumbi
Ubomi bobuqu: iminyaka eyi-2
I-Fiber esekelwe, i-sealant yokushisa okuphezulu
Emva kweminyaka emi-5+ yophando kunye nophuhliso, siyila kwaye senza olu luhlu lwekhompawundi yokutywina yokuvuza kobushushu obuphezulu. Ifayibha ekhethekileyo ikhethwa kwiintlobo ezingaphezu kwama-30 zeentsinga kwaye zidityaniswe neekhompawundi ezingaphezu kwe-10 ezahlukeneyo ze-inorganic ukuvelisa le mveliso. Ibonisa ukusebenza okugqwesileyo ngexesha lovavanyo lobushushu obuphezulu kunye novavanyo lokubuyiswa komlilo, kwaye iba yimveliso yethu ephambili.
Uphawu: Ukunganyangi, ukuthembela okugqwesileyo phantsi kobushushu obuphezulu, obusebenzayo kwi-flange, umbhobho, iivalve, iibhokisi zokugxusha.
Uluhlu lobushushu: 100℃~800℃ (212℉～1472℉)
Iimeko zokuGcina: ubushushu begumbi
Ubomi bobuqu: iminyaka eyi-2
Uluhlu ngalunye lweekhompawundi ezingentla lunokhetho olwahlukileyo.
