Tsananguro:
DCDA-Dicyandiamideimusanganiswa wemakemikari unoshandiswa zvakasiyana-siyana uye unoshandiswa zvakasiyana-siyana mumaindasitiri akasiyana. Iupfu hwemakristaro machena. Hunonyungudika mumvura, doro, ethylene glycol uye dimethylformamide, haunyungudike mu ether ne benzene. Hahutsvi. Hunogara kwenguva refu kana hwaoma.
Chikumbiro Chakapihwa:
1) Indasitiri yekurapa mvura: DCDA inoshandiswa mukurapa mvura, kunyanya mukudzivirira maruva emugungwa. Inoshanda semushonga wealgic nekudzivisa kukura nekuberekana kwemarudzi ealgae, ichibatsira kuchengetedza hunhu hwemvura mumatangi, madziva, uye munzvimbo dzemvura.
2) Indasitiri yemishonga: Dicyandiamide inoshandiswa mukugadzirwa kwemishonga, kusanganisira kugadzirwa kwemishonga yakati, madhayi, uye mamorekuru anoshanda muhupenyu. Inoshanda sechivako chemaitiro akasiyana-siyana emakemikari mukutsvaga nekugadzira mishonga.
3) Kurima: Dicyandiamide inonyanya kushandiswa muindasitiri yekurima semushonga wekusimbisa nitrogen uye wekugadzirisa ivhu. Inowanzo shandiswa semushonga wekuwedzera fertilizer kuti ivandudze kushanda kwenitrogen zvakanaka uye kuderedza kurasikirwa nenitrogen. DCDA yakakodzera zvirimwa zvakasiyana-siyana, zvinosanganisira zviyo, michero, miriwo, uye zvirimwa zvekushongedza.
4) Mushonga wekupisa weEpoxy resin: DCDA inoshandiswa semushonga wekupisa we epoxy resin, zvichibatsira mukuita kwavo cross-linking uye polymerization processes. Inowedzera hunhu hwemakanika, kunamira, uye kuramba kwemakemikari kwe epoxy-based coatings, adhesives, uye composites.
5) Zvinodzivisa moto: Dicyandiamide inoshandiswawo muzvinhu zvinodzivisa moto. Inobatsira kuderedza kupisa kwezvinhu zvakaita semapurasitiki nemachira, nekushanda semushonga unodzivirira moto une nitrogen.
Mhedziso:
Dicyandiamide (DCDA)ikemikari inokosha ine mashandisirwo akasiyana-siyana mukurima, kurapwa nemvura, mishonga, epoxy resin kuporesa, uye kunonoka kwemurazvo. Hunhu hwayo hwenitrogen inoburitswa zvishoma nezvishoma, mabhenefiti ayo ekugadziridza ivhu, uye mabhenefiti ezvakatipoteredza zvinoita kuti ive chishandiso chakakosha mukusimudzira nzira dzekurima dzinogara kwenguva refu uye kuderedza kusvibiswa kwezvinovaka muviri.
Kushanda nesimba kweDCDA mumaindasitiri akasiyana-siyana kunoratidza kukosha kwayo semusanganiswa unobatsira mukuvandudzwa kwekugadzirwa kwezvirimwa, mhando yemvura, mashandiro ezvinhu, uye kugadzirwa kwemakemikari. Kubata nemazvo, kutevedzera mitemo yekuchengetedza, uye kushandisa Dicyandiamide zvine hungwaru kunoita kuti ishandiswe zvakanaka uku ichideredza njodzi dzinogona kuitika.
Tiri kugadzira makemikari ekurapa mvura yakasviba kwemakore anopfuura makumi matatu, zvigadzirwa zvikuru iPAC, PAM, Water decoloring agent, PDADMAC, nezvimwewo. Kana muchida, ndapota musazeza kutibata.
