Ukusetyenziswa kweeMveliso
I-Fumaric acid isetyenziselwa ukuveliswa kwee-polyester resins ezingaxutywanga. Olu hlobo lwe-resin lubonakaliswe ngokumelana neekhemikhali ezilungileyo kunye nokuchasana nokushisa; i-copolymer ye-fumaric acid kunye ne-vinyl acetate yinto efanelekileyo yokubambelela. I-Copolymer ene-styrene yimathiriyeli ekrwada yokwenza i-FRP. I-plasticizer eyenziwe nge-fumaric acid ayinayo ityhefu kwaye ingasetyenziselwa i-vinyl acetate latex xa idibene nokutya. Le mveliso yikhemikhali elungileyo ephakathi efana neyeza kunye ne-agent ye-optical bleaching. Isetyenziselwa ukuveliswa kwe-antidote dimercaptosuccinic acid kwishishini lamachiza. I-asidi ye-fumaric ingathathi hlangothi kunye ne-sodium carbonate ukufumana i-sodium fumarate ( [17013-01-3] ), kwaye indawo yayo ifakwe i-ferrous sulfate ukuze ifumane i-iron fumarate, esetyenziselwa ukunyanga i-anemia encinci ye-cell blood cell kunye neziyobisi ezinentsimbi. Le mveliso isetyenziswa njenge-additive-sour agent, esetyenziselwa iziselo ezihlaziyayo, i-candy yeziqhamo, i-jelly, i-ayisikrimu, njl., Uninzi lwazo lusetyenziswa ngokudibanisa ne-agent emuncu ye-citric acid. Ityuwa ye-monosodium eyenziwe yi-reaction ye-fumaric acid kunye ne-sodium hydroxide, Ikwasetyenziswa njenge-seasoning emuncu kunye ne-intermediate ye-synthetic resin kunye ne-mordant.
1. Amasuntswana earhente ye-Acid ngenkqubo yokufakela, akulula ukuba ibe yintlekisa, ukusetyenziswa kothuli.
2. Thintela ukusabela kweekhemikhali ngezinye izinto ezikrwada nezincedisayo
3. Ukulinganisa i-symmetry, ubungakanani be-particle bungenziwa ngokwezifiso ngokweemfuno zabathengi
4. Ukukhutshwa kwe-Acid kucotha, kwandisa incasa yemveliso.
5. Njengomgubo wokugquma, unokuthintela ukunamathela kwemveliso, ukwandisa ubomi beshelufu yemveliso.
Ukupakishwa kunye noGcino
Umqulu:ipakishwe kwingxowa ephothiweyo yeplastiki engenamanzi, 25kg ngebhegi nganye okanye njengeemfuno zakho.
Phawula: Ukwakhiwa kweekhemikhali kunye nobukhulu bunokulungiswa ngokweemfuno zabathengi
Ugcino:
Igcinwe kwindawo engena umoya, inqanda imvula, ukufuma kunye nokuzivalela. Nceda uphathe ngononophelo ukuthintela umonakalo wengxowa, gcina kude kwizinto eziyityhefu.
Ukhuseleko loKhuseleko
Izilumkiso zokuphatha ngokukhuselekileyo
AKUKHO amadangatye avulekileyo. THINTELA UKUSASAZWA KOTHULI. Inkqubo evaliweyo, izixhobo zombane ezingaqhushumbayo kunye nezibane. Ukuphatha kwindawo engena umoya. Nxiba iimpahla ezifanelekileyo zokuzikhusela. Kuphephe ukudibana nolusu namehlo. Kuphephe ukubunjwa kothuli kunye ne-aerosols. Sebenzisa izixhobo ezingatshisiyo.
