Ko te tikanga whakamaroke me te rokiroki tika o nga riipene phosphate refractory castables

Ko te whakamaarama o te Phosphate e pa ana ki te peera kua honoa ki te waikawa phosphoric, phosphate ranei, a ko tana tikanga whakapakeke e pa ana ki te momo here e whakamahia ana me te tikanga whakapakeke.

Ko te kaihere o te phosphate castable ka taea te waikawa phosphoric he otinga whakauru ranei o te konumohe dihydrogen phosphate i hangaia e te hohenga o te waikawa phosphoric me te konumohe hydroxide. Ko te tikanga, karekau te here me te konumohe silicate e tauhohe i te pāmahana rūma (haunga te rino). Me whakamahana ki te whakamakuku me te whakakoi i te kaihere me te hono i te paura whakahiato kia whiwhi ai te kaha i te pāmahana rūma.

I te wa e whakamahia ana te coagulant, kaore e hiahiatia te whakamahana, ka taea te taapiri i te paura magnesia pai, te sima alumina teitei ranei hei whakatere i te coagulation. Ina tāpirihia te paura pai konupora waikura, ka tere te tauhohenga me te waikawa ūkuikui ka puta, ka noho, ka whakapakeketia nga mea whakakeke. Ina taapirihia te sima aluminate, ka hangahia nga phosphates he pai nga ahuatanga o te reera, he wai-wai kei roto penei i te calcium monohydrogen phosphate, te diphosphate ranei. Ko te konupūmā hauwai, aha atu, ka whakapakeke, ka whakapakeke te rauemi.

Mai i te tikanga whakapakeke o te waikawa phosphoric me te phosphate refractory castables, e mohiotia ana ka tika ana te tere tauhohenga i waenga i te ciment me nga whakahiato me nga paura i te wa o te whakamahana ka taea te hanga i tetahi castable tino pai. Heoi, he ngawari noa te kawe mai i nga rauemi mata kore ki roto i te tukanga o te mira, te mira poro me te ranu. Ka tauhohe ratou ki te kaihoko cimenting me te tuku hauwai i te wa e ranu ana, ka pupuhi te riipene whakakorikori, ka wetewete te hanga me te whakaiti i te kaha compressive. He kino tenei mo te hanga o te waikawa phosphoric noa me te phosphate castables refractory.
