Incazelo:
I-DCDA-Dicyandiamideiyinhlanganisela yamakhemikhali ehlukahlukene enezindlela eziningi zokusetshenziswa emikhakheni ehlukene. Iyimpuphu yekristalu emhlophe. Iyancibilika emanzini, utshwala, i-ethylene glycol kanye ne-dimethylformamide, ayincibiliki ku-ether kanye ne-benzene. Ayishi. Izinzile uma yomile.
Isicelo Esifakiwe:
1) Imboni yokwelapha amanzi: I-DCDA ithola ukusetshenziswa ezinqubweni zokwelashwa kwamanzi, ikakhulukazi ekulawuleni izimbali ze-algal. Isebenza njengesibulali-zinambuzane ngokuvimbela ukukhula nokuzala kwezinhlobo ezithile ze-algae, isiza ekugcineni ikhwalithi yamanzi emachibini, emachibini nasezindaweni zamanzi.
2) Imboni Yemithi: I-Dicyandiamide isetshenziswa ekuhlanganiseni amakhemikhali emithi, okuhlanganisa nokukhiqizwa kwemithi ethile, udayi, kanye nama-molecule asebenzayo ngokwezinto eziphilayo. Isebenza njengesisekelo sokusabela kwamakhemikhali ahlukahlukene ocwaningweni nasekuthuthukisweni kwemithi.
3) Ezolimo: I-Dicyandiamide isetshenziswa kakhulu embonini yezolimo njengesithambisi se-nitrogen kanye nesithambisi somhlabathi. Ivame ukusetshenziswa njengesithasiselo sikamanyolo ukuthuthukisa ukusebenza kahle kwe-nitrogen nokunciphisa ukulahleka kwe-nitrogen. I-DCDA ifanelekela izinhlobo eziningi zezitshalo, okuhlanganisa okusanhlamvu, izithelo, imifino kanye nezitshalo zokuhlobisa.
4) I-epoxy resin curing agent: I-DCDA isetshenziswa njenge-ejenti curing yama-epoxy resin, inegalelo ezinqubweni zawo zokuxhumanisa kanye ne-polymerization. Ithuthukisa izakhiwo zemishini, ukunamathela, kanye nokumelana kwamakhemikhali kwezembozo ezisekelwe ku-epoxy, izinamathiseli, kanye nezinhlanganisela.
5) Izinto ezivimbela ilangabi: I-Dicyandiamide isetshenziswa futhi njengengxenye yezinto ezivimbela ilangabi. Iyasiza ekunciphiseni ukusha kwezinto, njengepulasitiki nezindwangu, ngokusebenza njengesivimbeli somlilo esisekelwe ku-nitrogen.
Isiphetho:
I-Dicyandiamide (i-DCDA)iyinhlanganisela yamakhemikhali ewusizo enezinhlelo ezahlukahlukene kwezolimo, ukwelashwa kwamanzi, imithi, ukwelapha i-epoxy resin, kanye nokuvimbela ilangabi. Izakhiwo zayo ze-nitrogen ezikhipha kancane, izinzuzo zokulungisa inhlabathi, kanye nezinzuzo zemvelo zenza kube ithuluzi elibalulekile ekukhuthazeni imikhuba yokulima esimeme kanye nokunciphisa ukungcola kwezakhamzimba.
Ukuguquguquka nokuthembeka kwe-DCDA ezimbonini ezahlukahlukene kugqamisa ukubaluleka kwayo njengenhlanganisela enegalelo ekuthuthukisweni kokukhiqizwa kwezitshalo, ikhwalithi yamanzi, ukusebenza kwezinto, kanye nokuhlanganiswa kwamakhemikhali. Ukuphathwa ngendlela efanele, ukunamathela eziqondisweni zokuphepha, kanye nokusetshenziswa kwe-Dicyandiamide ngokwethembeka kuqinisekisa ukusetshenziswa kwayo ngempumelelo ngenkathi kunciphisa noma yiziphi izingozi ezingaba khona.
Sekuyiminyaka engaphezu kwengu-30 sikhiqiza amakhemikhali okwelapha amanzi amdaka, imikhiqizo eyinhloko yi-PAC, i-PAM, i-ejenti yokususa umbala emanzini, i-PDADMAC, njll. Uma udinga, sicela ukhululeke ukuxhumana nathi.
