Tlhaloso:
DCDA-Dicyandiamideke motsoako oa lik'hemik'hale o feto-fetohang o nang le mefuta e mengata ea ts'ebeliso indastering e fapaneng. Ke phofo ea kristale e tšoeu. E qhibiliha ka metsing, joala, ethylene glycol le dimethylformamide, ha e qhibilihe ka har'a ether le benzene. Ha e chese. E tsitsitse ha e omme.
Kopo e Fanoeng:
1) Indasteri ea kalafo ea metsi: DCDA e sebelisa mekhoa ea phekolo ea metsi, haholo-holo taolong ea lipalesa tsa bolele. E sebetsa e le sebolaya-mafu ka ho thibela kholo le ho ikatisa ha mefuta e itseng ea bolele, e thusa ho boloka boleng ba metsi matamong a metsi, matamong le libakeng tsa metsi.
2) Indasteri ea meriana: Dicyandiamide e sebelisoa ho kopanyeng metsoako ea meriana, ho kenyeletsoa le tlhahiso ea meriana e itseng, lidae le limolek'hule tse sebetsang ka baeloji. E sebetsa e le motheo oa likarabelo tse fapaneng tsa lik'hemik'hale lipatlisisong le nts'etsopele ea meriana.
3) Temo: Dicyandiamide e sebediswa haholo indastering ya temo e le ntho e tsitsisang naetrojene le ho lokisa mobu. E sebediswa hangata e le ntho e eketsang manyolo ho ntlafatsa bokgoni ba naetrojene le ho fokotsa tahlehelo ya naetrojene. DCDA e loketse dijalo tse fapaneng, ho kenyeletswa dijo-thollo, ditholwana, meroho le dimela tsa mekhabiso.
4) Moemeli oa ho phekola resin ea epoxy: DCDA e sebelisoa e le moemeli oa ho phekola resin ea epoxy, e tlatsetsang lits'ebetsong tsa tsona tsa ho hokahanya le ho etsa polymerization. E ntlafatsa thepa ea mechini, ho khomarela le ho hanyetsa lik'hemik'hale tsa liphahlo tse thehiloeng ho epoxy, likhomaretsi le metsoako.
5) Dithibela-malakabe: Dicyandiamide e boetse e sebediswa e le karolo ya dihlahiswa tse thibelang malakabe. E thusa ho fokotsa ho tuka ha thepa, jwalo ka dipolasetiki le masela, ka ho sebetsa e le dithibela-malakabe tse thehilweng ho naetrojene.
Qetello:
Dicyandiamide (DCDA)ke motsoako oa bohlokoa oa lik'hemik'hale o nang le lits'ebetso tse fapaneng temong, kalafo ea metsi, meriana, ho phekola resin ea epoxy, le ho lieha ha malakabe. Thepa ea eona ea naetrojene e lokolloang butle, melemo ea ho lokisa mobu, le melemo ea tikoloho li etsa hore e be sesebelisoa sa bohlokoa ho ntšetseng pele mekhoa ea temo e tsitsitseng le ho fokotsa tšilafalo ea limatlafatsi.
Ho tenyetseha le ho tšepahala ha DCDA indastering e fapaneng ho totobatsa bohlokoa ba eona e le motsoako o tlatsetsang tlhahisong e ntlafetseng ea lijalo, boleng ba metsi, ts'ebetso ea thepa le tlhahiso ea lik'hemik'hale. Tšebetso e nepahetseng, ho latela litataiso tsa polokeho, le tšebeliso e nang le boikarabelo ea Dicyandiamide li netefatsa ts'ebeliso ea eona e sebetsang ha ka nako e ts'oanang ho fokotsa likotsi life kapa life tse ka bang teng.
Re ntse re etsa lik'hemik'hale tsa kalafo ea metsi a litšila ka lilemo tse fetang 30, lihlahisoa tse ka sehloohong ke PAC, PAM, moemeli oa ho tlosa 'mala oa metsi, PDADMAC, jj. Haeba u hloka, ka kopo ikutloe u lokolohile ho ikopanya le rona.
