Ukusetshenziswa Kwemikhiqizo
I-Fumaric acid isetshenziswa ekukhiqizeni ama-polyester resins angenalutho. Lolu hlobo lwe-resin lubonakala ngokumelana okuhle kwamakhemikhali nokumelana nokushisa; i-copolymer ye-fumaric acid ne-vinyl acetate iyingcina enhle. I-Copolymer ene-styrene iyimpahla eluhlaza yokukhiqiza i-FRP. I-plasticizer eyenziwe nge-fumaric acid ayinabo ubuthi futhi ingasetshenziselwa i-vinyl acetate latex lapho ihlangana nokudla. Lo mkhiqizo uyikhemikhali enhle emaphakathi njengomuthi kanye ne-optical bleaching agent. Isetshenziselwa ukukhiqizwa kwe-antidote dimercaptosuccinic acid embonini yezemithi. I-fumaric acid ihlukaniswa ne-sodium carbonate ukuze kutholwe i-sodium fumarate ( [17013-01-3]), bese ithathelwa indawo yi-ferrous sulfate ukuze kutholwe i-iron fumarate, esetshenziselwa ukwelapha i-anemia encane yamangqamuzana egazi abomvu ngemithi enothe ngensimbi. Lo mkhiqizo usetshenziswa njenge-additive-sour agent, esetshenziswa eziphuzweni eziqabulayo, uswidi wezithelo, ijeli, u-ayisikhilimu, njll., eziningi zazo ezisetshenziswa ngokuhambisana ne-agent emuncu citric acid. Usawoti we-monosodium owenziwe ukusabela kwe-fumaric acid ne-sodium hydroxide, Usetshenziswa futhi njengesinongo esimuncu futhi njengesiphakathi se-synthetic resin ne-mordant.
1. Izinhlayiya ze-ejenti ye-Acid ngenqubo yokushumeka, akulula ukuba yindida, ukusetshenziswa kothuli
2. Vimbela ukusabela kwamakhemikhali nezinye izinto ezingavuthiwe neziyisizayo
3. I-symmetry yokushumeka, usayizi wezinhlayiyana ungenziwa ngokwezifiso ngokuya ngezidingo zekhasimende
4. Ukukhishwa kwe-Acid kuhamba kancane, khulisa ukunambitheka komkhiqizo.
5. Njenge-powder yokugqoka, ingavimbela ukunamathela komkhiqizo, yandise impilo yeshalofu yomkhiqizo.
Iphakheji Nesitoreji
Iphakheji:ifakwe esikhwameni esilukiwe sepulasitiki esingangeni emanzini, 25kg isikhwama ngasinye noma njengezidingo zakho.
Phawula: Ukwakheka kwekhemikhali nosayizi kungenziwa ngokugcwele ngezidingo zamakhasimende
Isitoreji:
Kuqoqwe endaweni engenawo umoya, kugwenywe imvula, umswakama kanye nokungenwa umoya. Sicela uphathe ngokucophelela ukuvikela ukulimala kwesikhwama, gcina kude nezinto ezinobuthi.
Ukuvikela Ukuphepha
Izinyathelo zokuphepha zokuphatha okuphephile
AKUKHO amalangabi avulekile. VIMELA UKUSAKAZEKA KOTHULI. Isistimu evaliwe, izinto zikagesi ezingaqhumi uthuli nokukhanyisa. Ukuphatha endaweni enomoya omuhle. Gqoka izingubo ezifanele zokuzivikela. Gwema ukuthinta isikhumba namehlo. Gwema ukwakheka kothuli nama-aerosol. Sebenzisa amathuluzi angashiyi izinhlansi. Vimbela umlilo obangelwa umusi wokukhipha i-electrostatic.
