E-China, imigwaqo yezindiza eminingi evamile yekhampasi, imigwaqo yezindiza ye-gymnasium, kanye nemizila yokuqina yonke imigwaqo yenjoloba egandaywe ngenjoloba.
Irabha yethrekhi yenjoloba iyinhlanganisela ye-polymer enwebeka kakhulu eyenziwe nge-latex yezihlahla zenjoloba, utshani benjoloba nezinye izitshalo, ezinwebekayo, ezivikelayo, ezingangeneki emanzini nasemoyeni.Ihlukaniswe yaba izinhlobo ezimbili: irabha yemvelo kanye nerabha yokwenziwa.Injoloba yemvelo yenziwa ngenhlaka etholakala ezihlahleni zenjoloba, utshani benjoloba nezinye izitshalo;Irabha yokwenziwa itholakala ku-polymerization yama-monomer ahlukahlukene.Imikhiqizo yenjoloba isetshenziswa kabanzi ezicini ezihlukahlukene zemboni noma ekuphileni kwansuku zonke.
Ithrekhi yenjoloba iyavumelana nezimo futhi iyanwebeka futhi iqashelwa emhlabeni jikelele njengento ehamba phambili yosuku lonke yangaphandle yenkundla yezemidlalo.Kodwa-ke, ngesikhathi sokusetshenziswa, izinto ezifana nethrekhi yenjoloba ukuthi ayingeneki, ayikwazi ukumelana nokuguga, ukuguga ngokushesha, nokunyamalala kokunwebeka.Ngakho-ke ungasebenzisa kanjani ijeneretha ye-steam ukuthuthukisa ukuqina kwethrekhi yenjoloba?Umhleli weNobelis uzofunda ngakho nawe namuhla:
Ukushisa okuphezulu kwe-steam kwandisa okuqukethwe kweglue
Irabha yethrekhi yenjoloba iyi-polymer eyenziwe nge-latex yezihlahla zenjoloba, utshani benjoloba nezinye izitshalo.Impahla eluhlaza kufanele ishisiswe ukuze incibilike ibe uketshezi lwerabha olune-viscous.Ukuphakama kwe-viscosity yoketshezi lwerabha, kuba ngcono ukunwebeka kwezinhlayiya ngemva kokupholisa nokuqiniswa.Ijeneretha yesitimu ingakhiqiza isitimu esiqhubekayo.Ama-molecule we-steam anezinga eliphezulu lokushisa ahlukaniswa ngokushesha ku-reactor, engashisisa izinhlayiya ngokulinganayo futhi yenze iphuzu lokuncibilika loketshezi lwerabha lihambisane, okungakhuphula kakhulu okuqukethwe kwerabha.
Ukulawula izinga lokushisa okunembile kuthuthukisa ukuqina
Ukulawula izinga lokushisa ngokwesayensi kubaluleke kakhulu.Ijeneretha yesitimu ingalawula ngokunembile izinga lokushisa lomusi ngokwezidingo zenqubo, ukuze izinhlayiya zincibilike ezingeni lokushisa elifanele.Lokhu akuqinisekisi kuphela ukuqina, kodwa futhi kwenza ithrekhi yenjoloba ibe bushelelezi futhi imelane nokucindezela.Inokuqina okuphezulu, ukunwebeka okufanele, ukusebenza komzimba okuzinzile, futhi ayijwayele ukuqhekeka, ukuxebuka, ukufiphala nokuba mhlophe.
I-Steam ishisa ngokushesha
Ijeneretha yesitimu ishisa ngokushesha futhi ingakhiqiza isitimu emizuzwini embalwa.Ishisisa i-reactor ngokushesha futhi isebenza kahle kakhulu.Ngesikhathi esifanayo, ukusebenzisa igesi njengophethiloli kunciphisa izindleko zikaphethiloli ngezinga elikhulu.Iphinde ifakwe idivayisi yokonga amandla engakwazi ukugaywa kabusha ukushisa kwemfucuza okukhiqizwa ngesikhathi sokufakwa kwemishini, enganciphisa izindleko cishe ngo-40%.Yingakho amajeneretha omusi esetshenziswa ekukhiqizweni kwezimboni ezinkulu.
