Ukwakheka kwengilazi kungenye yezinto eziyinhloko ezinquma uhlobo lwengilazi, ngakho-ke, ukwakheka kwamakhemikhali ebhodlela lengilazi futhi kufanele kuqala kuhlangabezane nezidingo zokusebenza ngokomzimba namakhemikhali kwebhodlela lengilazi futhi, ngesikhathi esifanayo ukuhlanganisa ukuncibilika, ukubumba. kanye nokucubungula ubuchwepheshe nokunye ukucatshangelwa okuphelele, ngaphezu kwalokho, kodwa futhi cabangela ukonga izindleko nokunciphisa ukungcoliswa.
1. Izithako zamabhodlela nezimbiza
2. Uhlobo lokubunjwa kwengilazi yebhodlela
Ngokusho kokuqukethwe okuhlukile kwengilazi yengilazi, ingahlukaniswa ibe izingxenye zengilazi ye-sodium calcium, izingxenye zengilazi ye-calcium ephezulu, izingxenye zengilazi ye-aluminium ephezulu, kodwa lokhu kuhlukaniswa akukona okuqinile, ukuze kube lula ucwaningo nokucacisa.
Ngokusho kwe-USES ehlukene yebhodlela kanye nengilazi yengilazi, ingabuye ihlukaniswe izingxenye zengilazi zamabhodlela kabhiya, izingxenye zengilazi zamabhodlela ewayini, izingxenye zengilazi, izingxenye zengilazi zamabhodlela emithi kanye nama-reagents kanye namakhemikhali amakhemikhali engilazi yengilazi.Ukuze kuncishiswe izindleko, izingxenye zengilazi kufanele zenzelwe ngokuvumelana nezidingo zokusebenza kwezinhlelo zokusebenza ezahlukene.
Okujwayelekile kakhulu kwasekhaya ukuhlukanisa ingxenye yengilazi yohlobo ngokuya ngethoni.Ngokwesiko, ihlukaniswe ngezinto ezimhlophe eziphakeme (Fe2O3<0.06%), izinto ezikhanyayo (impahla emhlophe evamile), impahla emhlophe eyingxenye (impahla ye-qingqing Fe2O3≤0.5%), impahla yombala, impahla emhlophe yobisi.Izinto ezivamile ezimhlophe eziphakeme ngokuvamile zisetshenziselwa amabhodlela ewayini ekhwalithi ephezulu namabhodlela ezimonyo.I-semi-white material isetshenziselwa amathini namabhodlela, aqukethe inani elithile le-Fez O 3, esetshenziselwa ikakhulukazi ukumunca imisebe ye-ultraviolet.Iqukethe i-Fe2O: <0.5%, futhi umkhawulo wemisebe ye-ultraviolet ungaphansi kuka-320nm.Ibhodlela likabhiya liluhlaza noma inhlaka, futhi umkhawulo wokumunca ucishe ube ngu-450nm.
