Whakamahinga

1.Ko nga reagents analytical e whakamahia ana, e whakamahia nuitia ana mo te whakakore, te waikawa ranei.Ko nga whakarewa whakaheke wai-kore, te whakareri i nga wairewa papaa, te whakahiato waro.Te hanga o nga poaka, nga raau taero, te muka acetate, te acetyl pūhui, me etahi atu. Ka whakamahia ano hoki ki te whakakore i te ūkuikui, te whanariki, te waikawa hydrohalic, me etahi atu. Hei kaihoko kawa, ka taea te whakamahi hei mea kakara, te whakarite i te winika, te kai kēne, te tiēre. me te tiihi, me te whakamahi i nga rahinga e tika ana kia rite ki nga hiahia whakaputa.Ka taea hoki te whakamahi hei whakanui i te reka mo te waipiro koji, a ko te nui e whakamahia ana he 0.1-0.3g/kg.Ka whakamahia hei whakarewa i roto i te hanga rapa, kirihou, waikano, me etahi atu Ka whakamahia ano he rauemi mata mo te hanga o te vinyl acetate, cellulose acetate, menthyl acetate, raau taero whakaahua, rongoa, pesticides me etahi atu whakahiato waro.
2.Ka whakamahia nga reagents tātari.Nga whakarewa mo te ao me nga whakarewa whakaheke wai-kore.Whakamahia i roto i te hanga o te acetate, cellulose acetate, rongoa, pigments, esters, kirihou, mea kakara, etc.
3.PH kaiwhakahaere uara.Ka taea te whakamahi mo te whakarite o te ethyl acetate, te whakarite i nga muka, te peita, te whakapiri, te copolymer resins, me etahi atu, te whakarite i te anhydride acetic, te waikawa chloroacetic, te waikawa glycolic me te pikinga ahumahi.
4.Ka taea te whakamahi mo te pikinga ahumahi.Mo te whakarite i nga muka, nga paninga, nga taapiri, nga kapia copolymer, etc.
5.He mea nui te matū matū matū, ka taea te whakaputa i nga momo momo matū matū.Ka whakamahia te ahumahi rongoa ki te whakarite i nga momo rongoa, ka whakamahia te ahumahi tae ki te hanga i nga momo momo tae, ka whakamahia te ahumahi rauemi waihanga ki te whakahiato i nga momo momo polymer, he mea nui te takawaenga matū waro.I tua atu, ka whakamahia ano hoki hei whakarewa ahumahi, hei hiako hiako, he rapa rapa coagulants, he awhina tae, he mea kakara, he reagents matū, me etahi atu, ka whakamahia ano hoki hei waikawa, hei whakanui i te reka, me era atu.
6.Ka taea te whakamahi i te waikawa acetic i roto i etahi otinga whakakoi me te whakakorikori, i roto i nga otinga waikawa ngoikore hei parepare (pēnei i te galvanizing, electroless nickel whakakikorua), i roto i te nickel whakakikorua electrolyte hei taapiri, i te zinc, ka taea e te otinga passivation cadmium te whakapai ake i te piri. o te kiriata passivation, me te whakamahi noa ki te whakatika i te pH o te otinga whakakikorua waikawa ngoikore, ka taea hoki te whakamahi hei whakarewa mo etahi taapiri waro (penei i te coumarin).
7.Ko nga reagents analytical e whakamahia ana, nga whakarewa whanui me nga whakarewa titration kore-wai, te whakahiato waro, te whakahiatotanga o nga poaka me nga rongoa.
8.I whakamahia i roto i te hanga o te acetate, te cellulose acetate, te rongoa, te pigments, te esters, te kirihou, nga mea kakara, me etahi atu.
