Kaiwhakakī mō te wai keri (80A51)
He paura mā, he kowhai mārama rānei tēnei hua, he mea whakarei ake i te matotoru o te pūmua hangai.
He kaha te ātete o tēnei hua ki te ngawari me te tote. I raro i te pāmahana teitei i runga ake i te 120℃, ka taea te whakanui ake i te matotoru whai hua o te wai keri ki te neke atu i te 25mPa.s mā te tāpiri noa i te 0.3%, ka taea ai te whakapai ake i te kaha kawe maramara me te thixotropy o te wai keri. I taua wā anō, ka taea hoki te whakamahi i tēnei hua hei whakaiti i te ngaronga wai.

Te tākai me te kawe waka
Whakamahia he putea kirihou whatu kua whakakikoruatia ki te 25kg, he putea pepa kirihou hiato rānei. Ka taea hoki te tākai kia rite ki ngā hiahia o te kaiwhakamahi. I te wā e rongoa ana, e kawe ana hoki, kia tūpato ki te tiaki i te wera me te makuku, kaua e neke ake i te 20 paparanga te paparanga whakarārangi. Ko te roanga rokiroki whai hua he 2 tau.
Ngā take e tika ana kia arohia:
Āraia te pā ki ngā kanohi, te kiri me ngā kākahu, horoia rānei ki te nui o te wai. Puritia kia matara atu i te ahi.
1. He aha ngā momo matū e whakamahia whānuitia ana i ngā mara hinu?
He maha ngā momo matū o te mara hinu e wātea ana hei whakatika i ngā wero motuhake i roto i te umanga hinu me te hau. Ko ngā matū e whakamahia whānuitia ana ko ngā patu huakita, ngā aukati waikura, ngā whakakore i ngā matū kino, ngā aukati unahi, ngā whakaiti waku, ngā kaihoroi matū, ngā emulsifier me ngā waikawa, me ētahi atu.
2. Me pēhea te hoko i ngā matū o te mara hinu?
Ka taea te hoko i ngā matū o te mara hinu mā roto i ngā kaiwhakarato matū whai raihana e tohunga ana ki ngā hua i hangaia mō ngā tono hinu me te hau. He maha ngā wā he rōpū tohunga motuhake ā ēnei kaiwhakarato ka taea te tuku tohutohu mō te whiriwhiri me te whakamahi i ngā matū e tika ana i runga i ngā whakaritenga motuhake.
