Whakaahuatanga:
DCDA-DicyandiamideHe matū maha-whakamahinga tēnei, he whānuitia ngā whakamahinga i roto i ngā ahumahi rerekē. He paura tioata mā. Ka wairewa i roto i te wai, te waipiro, te ethylene glycol me te dimethylformamide, kāore e wairewa i roto i te ether me te benzene. Kāore e mura. Ka pumau ina maroke.
Tono i Tukuna:
1) Te umanga maimoatanga wai: Ka whakamahia te DCDA i roto i ngā tukanga maimoatanga wai, inā koa i roto i te whakahaere i te puāwaitanga o ngā rimurimu. Ka mahi hei patu rimurimu mā te aukati i te tipu me te whakaputa uri o ētahi momo rimurimu, ā, ka āwhina ki te pupuri i te kounga o te wai i roto i ngā puna wai, ngā roto me ngā wai.
2) Ahumahi rongoā: Ka whakamahia te dicyandiamide i roto i te hanganga o ngā matū rongoā, tae atu ki te hanga i ētahi rongoā, tae, me ngā ngota koiora hohe. He poraka hanga tēnei mō ngā tauhohenga matū maha i roto i te rangahau me te whanaketanga rongoā.
3) Ahuwhenua: Ko te Dicyandiamide te mea nui e whakamahia ana i roto i te umanga ahuwhenua hei whakaū hauota me te whakangawari oneone. He mea whakamahi noa hei tāpiri tongi hei whakapai ake i te whai huatanga o te hauota me te whakaiti i te ngaronga o te hauota. He pai te DCDA mō te whānuitanga o ngā hua, tae atu ki ngā witi, ngā hua rākau, ngā huawhenua, me ngā tipu whakapaipai.
4) Kaiwhakaora kapia epoxy: Ka whakamahia te DCDA hei kaiwhakaora mō ngā kapia epoxy, e whai wāhi ana ki ā rātou tukanga honohono me te whakapūhui. Ka whakarei ake i ngā āhuatanga hangarau, te piri, me te ātete matū o ngā paninga e hangai ana ki te epoxy, ngā piripiri, me ngā mea whakahiato.
5) Ngā ārai mura: Ka whakamahia hoki te dicyandiamide hei wāhanga o ngā whakatakotoranga ārai mura. Ka āwhina i te whakaiti i te mura o ngā rauemi, pērā i ngā kirihou me ngā kakahu, mā te mahi hei ārai mura i te hauota.
Whakatau:
Dicyandiamide (DCDA)He matū whai hua te matū nei, he maha ngā whakamahinga i roto i te ahuwhenua, te maimoatanga wai, ngā rongoā, te whakamaroke i te kapia epoxy, me te ātete mura. Nā ōna āhuatanga hauota tuku puhoi, ōna painga whakangawari oneone, me ōna painga taiao, he mea nui tēnei hei taputapu whakatairanga i ngā mahi ahuwhenua tauwhiro me te whakaiti i te parahanga matūkai.
Ko te maha o ngā mahi a te DCDA me tōna pono i roto i ngā momo ahumahi e whakaatu ana i tōna hiranga hei matū e whai wāhi ana ki te whakapai ake i te whakaputanga hua, te kounga wai, te mahi rauemi, me te hanganga matū. Ko te whakahaere tika, te piri ki ngā aratohu haumaru, me te whakamahinga tika o te Dicyandiamide ka whakarite kia whai hua te whakamahinga me te whakaiti i ngā tūponotanga.
Neke atu i te 30 tau mātou e hanga ana i ngā matū maimoatanga wai para, ko ngā hua matua ko te PAC, te PAM, te kaiwhakakore tae wai, te PDADMAC, me ētahi atu. Mena e hiahia ana koe, tēnā whakapā mai.
