I-Medical Imaging History of Barium Sulfate Ukusetshenziswa kwe-barium sulfate njenge-agent ehlukile kwaqala ekuqaleni kwekhulu lama-20, lapho odokotela bethola ukuthi le nto ingathuthukisa ngokuphumelelayo ukuhlukana kwezithombe ze-X-ray, okwenza isakhiwo sangaphakathi somzimba sicace futhi sibonakale. Phezu kwethi

Isingeniso I-Benzoic acid iyinhlanganisela ye-organic enefomula yamakhemikhali i-C8H7O2, esetshenziswa kakhulu embonini nempilo yansuku zonke. Emkhakheni wezimboni, i-benzoic acid isetshenziselwa ikakhulukazi ukukhiqiza i-phenol, okuwumthombo oyinhloko wokukhiqiza imikhiqizo efana nepulasitiki, ama-resin, imithi kanye nodayi.

Isingeniso I-Benzoic acid iyinhlanganisela ye-organic enefomula yamakhemikhali ethi C6H5COOH, enesakhiwo sendandatho ye-benzene kanye neqembu elisebenzayo le-carboxyl. Ngenxa yesakhiwo sayo samakhemikhali esiyingqayizivele nezakhiwo, i-benzoic acid idlala indima ebalulekile embonini yezimonyo nezingubo, futhi isetshenziswa kabanzi.

Izakhiwo eziyisisekelo ze-boric acid I-Boric acid iyimpushana emhlophe ecwebezelayo enokunambitheka okune-acidic kancane kanye nokuthungwa okubushelelezi. Amakhemikhali ayo azinzile futhi akulula ukusabela nezinye izinto, okwenza ibe neshalofu isikhathi eside emikhiqizweni yezemithi. Ukusetshenziswa kwe-boric ac

Isingeniso I-Benzoic acid iyinhlanganisela ye-organic enefomula yamakhemikhali i-C8H7O2, esetshenziswa kakhulu embonini nempilo yansuku zonke. Emkhakheni wezimboni, i-benzoic acid isetshenziselwa ikakhulukazi ukukhiqiza i-phenol, okuwumthombo oyinhloko wokukhiqiza imikhiqizo efana nepulasitiki, ama-resin, imithi kanye nodayi.

Ukusetshenziswa kwe-caustic soda ekukhiqizeni insipho Insipho iyi-ejenti yokuhlanza yasendulo, ikakhulukazi eyakhiwe ngosawoti omningi we-acid enamafutha. Ukukhiqizwa kwensipho kuvame ukufezwa ngokusabela kwe-saponification, okubandakanya ukusabela kwamafutha (njengamafutha ezilwane nezitshalo, amafutha) ane-caustic soda. I-Caustic

Ukusetshenziswa okuyinhloko kwe-caustic soda ekukhiqizeni izinto zokusetshenziswa zamakhemikhali. Ekuphenduleni kwe-saponification, uwoyela uhlangana ne-caustic soda ukukhiqiza insipho ne-glycerol. Ngaphezu kwalokho, i-caustic sod

Ukwelashwa kwangaphambili kwezindwangu Enqubweni yokukhiqizwa kwezindwangu, i-caustic soda ivame ukusetshenziswa esigabeni sokwelashwa kwangaphambi kokwelashwa. Ingasusa ukungcola kwemvelo okufana ne-wax, i-pectin, i-cellulose, njll. emiculweni yemvelo efana nekotini ne-hemp, futhi le nqubo ibizwa ngokuthi i-degreasing. Ukusetshenziswa kwe-caustic soda

Ukusetshenziswa okuyinhloko embonini yokwenza amaphepha1. Ukukhiqizwa kwe-pulpEnqubweni yokukhiqiza ye-pulp, i-caustic soda isetshenziselwa ikakhulukazi ukulungiswa kwe-pulp yamakhemikhali. Ngokuphatha izinkuni nge-caustic soda, i-lignin ingahlukaniswa ngokuphumelelayo ne-cellulose, futhi le nqubo ibizwa ngokuthi i-delignification. I-pulp

Izakhiwo eziyisisekelo ze-calcium nitrite I-Calcium nitrite (Ca (NO2) 2) iyinhlanganisela ye-inorganic, engenambala noma i-crystalline ephuzi kancane, ene-deliquescence kanye nokuncibilika kalula emanzini. Ezimbonini, i-calcium nitrite ivame ukusetshenziswa njengesengezo sikasimende, i-rust inhibitor, i-antifreeze, kanye
