Uphalafini KT-1. Imininingwane
Izici zokwakheka kanye nezakhiwo
Izidingo zokulawula ezilawula ukukhiqizwa nokusetshenziswa kukaphalafini we-KT-1 zinikezwa ku-GOST 18499-73. Lo mbhalo uchaza uphalafini wobuchwepheshe njengento evuthayo esetshenziselwa izinjongo zezimboni noma njengomkhiqizo osuqedwe kancane ukuze kukhiqizwe ezinye izinhlobo ze-hydrocarbon.
I-kerosene yezobuchwepheshe i-KT-1 ikhiqizwa ngezigaba ezimbili zekhwalithi - ephezulu kakhulu neyokuqala. Umehluko phakathi kwawo ukhonjiswe kuthebula:
| Igama lepharamitha | I-unit of measurement | Inani lenombolo likaphalafini lobuchwepheshe | |
| isigaba sokuqala | isigaba sesibili | ||
| Ibanga lokushisa le-distillation | ºС | 130… 180 | 110… 180 |
| Ukuminyana ekamelweni lokushisa, akusekho | t/m3 | 0,820 | Ayilawulwa, kodwa iqinisekisiwe |
| Nciphisa okuqukethwe kwesibabule | % | 0,12 | 1,0 |
| Okuqukethwe okuphezulu kakhulu kwe-resinous substance | % | 12 | 40 |
| I-Flash point | ºС | 35 | 28 |
I-GOST 18499-73 futhi isungula izindinganiso zokumelana nokugqwala kwemikhiqizo kuphalafini lobuchwepheshe, kanye nezinkomba zokuqukethwe komlotha kanye ne-acidity. Uma isetshenziswa njengesihlanzi, izakhi eziqukethe usawoti oncibilikayo we-magnesium noma i-chromium zingeniswa ekwakhiweni kukaphalafini KT-1. Bandisa ukumelana kwe-electrostatic kwemikhiqizo ecutshunguliwe.
I-Kerosene KT-1 nayo isetshenziswa njengesengezo kuphethiloli we-diesel wendabuko, osetshenziswa ehlobo.
Uphalafini lobuchwepheshe KT-2
IBanga le-KT-2 lihlukaniswa ngokuqukethwe okuphansi kwama-hydrocarbons anephunga elimnandi, ngakho-ke linephunga elimnandi futhi lingasetshenziswa ukuhlanza izingxenye ezihambayo zemishini yokucubungula. Izithasiselo eziqukethwe kupharafini yebanga le-KT-2 zisiza ukwehlisa ukugqokwa kwe-oxidative. Izinkomba zayo eziyinhloko - okuqukethwe komlotha, indawo ekhanyayo, ukuminyana - ziphakeme kunezinga likaphalafini le-KT-1.
Esinye isici sikaphalafini wezobuchwepheshe we-KT-2 yikhono lokuqhwa emazingeni okushisa aphansi, ngakho-ke isetshenziswa kaningi njengesithasiselo samabanga ebusika kaphethiloli wedizili kune-KT-1.
I-Kerosene KT-2 iyadingeka embonini yamakhemikhali, emabhizinisini akhiqiza i-ethylene kanye nokuphuma kwayo ngendlela ye-pyrolytic. Uhlobo lwe-KT lwalubuye lusetshenziswe kabanzi embonini ye-ceramic nasekwenzeni izinto eziphikisayo, imikhiqizo ye-porcelain ne-faience. Kuzo zonke lezi zimo, amandla aphezulu kaphalafini kanye nekhono lawo lokuvutha okuphelele kakhulu emazingeni okushisa aphezulu asetshenziswayo.
Izimo zokugcina
Njengezinye izinhlobo zikaphalafini - TS-1, KO-25, njll - uphalafini lobuchwepheshe i-KT-1 ne-KT-2 ifuna ngenkani ngemibandela yokugcinwa kwayo. I-GOST 18499-73 ikhawulela isikhathi sokugcina unyaka owodwa, emva kwalokho, ukuze kunqunywe ukufaneleka kwe-parafini yobuchwepheshe ukuze isetshenziswe, ukuhlolwa okwengeziwe kuyadingeka. Qaphela ukuthi ngesikhathi sokugcina, i-parafini yezobuchwepheshe iyakwazi ukuqeda futhi yakha ukungcola kwemishini, futhi okuqukethwe kwe-resinous substances kuyo kuyanda.
Igumbi okugcinwa kulo iziqukathi ezivalwe ngophalafini lobuchwepheshe i-KT-1 noma i-KT-2 kufanele lifakwe izicishamlilo ezisebenzisekayo (igwebu noma izicishamlilo ze-carbon dioxide), zibe nezinto ezisetshenziswayo zikagesi ezisebenzisekayo futhi zihlale zisebenza futhi zikhiphe umoya okhipha umoya. Kudingeka ukusebenzela endlini ngezinto zokuzivikela futhi usebenzise amathuluzi okusebenza angangenhlansi kuphela.
