Inkcazo:
I-DCDA-DicyandiamideYikhemikhali esetyenziswa ngeendlela ezahlukeneyo enokusetyenziswa kwiindawo ezahlukeneyo. Yi-White crystal powder. Iyanyibilika emanzini, kutywala, kwi-ethylene glycol nakwi-dimethylformamide, ayinyibiliki kwi-ether nakwi-benzene. Ayitshi. Izinzile xa yomile.
Isicelo Esifakiweyo:
1) Ishishini lokunyanga amanzi: I-DCDA isetyenziswa kwiinkqubo zokunyanga amanzi, ingakumbi ekulawuleni iintyatyambo ze-algal. Isebenza njenge-algicide ngokuthintela ukukhula nokuzala kweentlobo ezithile ze-algae, inceda ukugcina umgangatho wamanzi kwiindawo zokugcina amanzi, amachibi, kunye neendawo zamanzi.
2) Ishishini leMithi: I-Dicyandiamide isetyenziswa ekuhlanganiseni iikhompawundi zamayeza, kuquka ukuveliswa kwamayeza athile, iidayi, kunye neemolekyuli ezisebenzayo kwibhayoloji. Isebenza njengesiseko sokwakha iimpembelelo ezahlukeneyo zeekhemikhali kuphando nophuhliso lwamayeza.
3) Ezolimo: I-Dicyandiamide isetyenziswa kakhulu kwishishini lezolimo njengesithambisi se-nitrogen kunye nesilungisi somhlaba. Isetyenziswa njengesichumisi ukuphucula ukusebenza kakuhle kwe-nitrogen kunye nokunciphisa ukulahleka kwe-nitrogen. I-DCDA ifanelekile kwiintlobo ngeentlobo zezityalo, kubandakanya iinkozo, iziqhamo, imifuno kunye nezityalo zokuhombisa.
4) I-epoxy resin curing agent: I-DCDA isetyenziswa njenge-epoxy resin, inegalelo kwiinkqubo zayo zokudibanisa kunye nokwenza i-polymerization ibe nkulu. Iphucula iipropati zoomatshini, ukunamathela, kunye nokumelana neekhemikhali kweengubo ezisekelwe kwi-epoxy, izincamathelisi, kunye nee-composites.
5) Izinto ezithintela umlilo: I-Dicyandiamide ikwasetyenziswa njengenxalenye yezinto ezithintela umlilo. Inceda ekunciphiseni ukutsha kwezinto, ezifana neeplastiki kunye neempahla, ngokusebenza njengezinto ezithintela umlilo ezisekelwe kwi-nitrogen.
Isiphelo:
I-Dicyandiamide (DCDA)yikhemikhali exabisekileyo enezicelo ezahlukeneyo kwezolimo, unyango lwamanzi, amayeza, ukunyanga i-epoxy resin, kunye nokungalali kakuhle. Iipropati zayo ze-nitrogen ezikhutshwa kancinci, iingenelo zokulungisa umhlaba, kunye neenzuzo zokusingqongileyo zenza ukuba ibe sisixhobo esibalulekileyo ekukhuthazeni iindlela zokulima ezizinzileyo kunye nokunciphisa ungcoliseko lwezondlo.
Ukuguquguquka nokuthembeka kwe-DCDA kumashishini ahlukeneyo kubonisa ukubaluleka kwayo njengekhompawundi enegalelo ekuphuculweni kwemveliso yezityalo, umgangatho wamanzi, ukusebenza kakuhle kwezinto, kunye nokuhlanganiswa kweekhemikhali. Ukuphathwa ngokufanelekileyo, ukuthotyelwa kwezikhokelo zokhuseleko, kunye nokusetyenziswa ngokufanelekileyo kweDicyandiamide kuqinisekisa ukusetyenziswa kwayo ngokufanelekileyo ngelixa kunciphisa naziphi na iingozi ezinokubakho.
Sele kudlule iminyaka engaphezu kwama-30 sisenza iikhemikhali zonyango lwamanzi amdaka, iimveliso eziphambili yi-PAC, i-PAM, iarhente yokususa umbala emanzini, i-PDADMAC, njl. Ukuba uyayifuna, nceda unxibelelane nathi.
