I tēnei wā, he rere kore te hiahia ki te dicalcium phosphate hei pūtake pai o te calcium me te phosphorus mō ngā kararehe āwhina me ngā manu, nā reira kua pānui ake ngā raruraru o te whakamāngō me te whakauru i ngā hua iti ake. Me pēhea te whiriwhiri i te dicalcium phosphate pai rawa mai i ngā whilihanga maha e wāhia ana?
Ko ngā whakamāngō mātua o te dicalcium phosphate ko: te parāoa o te kōhatu, te one, te tricalcium phosphate, te superphosphate āwhina, te parāoa o te kōhatu phosphate, me te calcium carbonate māma. Ko ngā ara whakamārama mō ia ko ngā whakamārama i raro nei.
1. Te Whakamārama i te Parāoa o te Kōhatu, i te Calcium Carbonate Māma:
Ko ngā pūtake o te kōhatu, i te whakamāmā i te 80 mesh, i te iti ake rānei, e rite ana ki te dicalcium phosphate i tōna āhua me ōna āhua, engari ko tōna tau pānga o te maha he nui ake. Ko te calcium carbonate mā, e rite ana ki te dicalcium phosphate i ngā āhua ā-huinga me te tau pānga o te maha, nā reira he uaua te rerekētanga i te titiro. Heoi anō, ka taea te whakamārama i te hāngī hāngī māmā. Ko ngā pūtake o te kōhatu me te calcium carbonate mā e whaiwhai ana i te hāngī hāngī māmā, e whakawhiti ana i ngā pūpū nui. I muri i te whakamārama, ko te wāhi he māmā ake.
2. Te whakamārama i te tricalcium phosphate:
Ko te tricalcium phosphate, i mōhiotia hoki hei calcium phosphate, he whero, he kākāriki-kākāriki, ā, he teitei ngā wāhanga o te phosphorus me te calcium (ahakoa kāore i te māmā ki te whaiwhai a ngā kararehe), nā reira he "mātūtū tino pai" hei whakamāngai i ngā kaihāpai kāore i te pono. Heoi anō, ka taea te whakamārama. Tīmata i tēnei: tīmata i tēnei: tango he iti o te tauā, whakaputua ki tēnei ipu iti, whakamātua ki te acetic acid iti, kātahi ka tāpirihia te whakamāhua tartaric acid me te ammonium molybdate hei whakamātua i te tauā. Whakaputua ki tēnei umu āhua rereke i te 60–70°C. I ngā miniti e toru, mēnā he whero te whakamātua, ko te whero he tohu mō te tricalcium phosphate.
3. Te whakamārama i te kōpū i te wāhi:
Ko te whāinga o te tāpiri i te phosphate dicalcium ki te pūpū kōiwi kia iti ake te mātua o te fluorine. Heoi anō, ko tana tae he pango-kākāriki, he kākāriki-kōwhai, he kōwhai-kākāriki, ā, mēnā ka tāpiri kia hāngā atu te wāhi hāngā, ka rere mai te hāngā o te pūpū kōiwi. Ko te whakamātautau anō, tīpakohia he iti (āhua 1–2g) o te phosphate dicalcium, tāpirihia te hāngā o te hārihi hāngā o te hydrochloric acid, ā, i muri i te whakamātautau, ka whanake te nui o ngā pūpū kōwhai kākāriki. I muri i te whakamātautau, ka kōwhai-kākāriki te wāhi, ā, ka noho ngā mea kāore i taea te whakamātautau i te rākau, e whakaatu ana i te wāhi o te pūpū kōiwi.
4. Te whakamātautau i te phosphate rock powder:
Ko te phosphate rock powder he pūpū iti i whakamahinga mai i te phosphate rock. Ko tana tae he pango-kākāriki, he kākāriki-kōwhai, he mā, ā, ko tana mātua o te fluorine he āhua 2%, ā, ko tana mātua o te calcium he āhua 32%. Kāore i taea te whakamātautau i te hārihi hāngā o te hydrochloric acid, ā, ka whakamahinga hei whakamātautau.
5. Te whakamātautau i te agricultural superphosphate:
Ko te superphosphate pākai mō te ahua kākahu he whero-kākahu ki te kākahu-pango. Inā he āhua pango-kākahu te wāhi i tāwhai ai te hāngā o te hydrochloric acid iti, me ngā wāhi kāore i tāwhai, e whakamāhi ana hei tātai mō te whakamātautau.
6. Te whakamātautau i te Talc:
He rite ngā āhua arotake o te talc ki ngā āhua o te phosphate calcium āhua pūmau, engari kāore i tāwhai i te hydrochloric acid iti, ā, he kākahu whakamārama e rere mai ana i te mata, e whakamāhi ana hei tātai mō te whakamātautau.
7. Ko te phosphate calcium āhua pūmau pai me being he pūpū kākahu, he kākahu-whero, he rite ngā āhua, he māmā te whakamāhi, he pai ngā āhua o te rere. Kāore i tāwhai i te wai, engari i tāwhai i te hāngā citric acid 2% me te hydrochloric acid 0.4% (kāore he pūrere e hanga mai i te tāwhai). Anō hoki, ka tāwhai he iti i te watch glass, ka tāwhai he iti o te hāngā silver nitrate 5%; ka huri te tauā i te pūrere kākahu.
I tēnā, ko te whakamārama o te pūtake o te tauira (HG2636-2000) he mea tātai i te āhua o te kālisiu me ngā wāhi e rite ana: me nui ake i te 21.0% te kālisiu, me nui ake i te 16.5% te fōsifō, ā, me iti ake i te 0.18% te fōrini. Kāore he rārangi o runga i tēnei, ā, he whakamārama tēnei hei whakamārama tuara mō ngā tauira kua whakauru kē. Heoi anō, ko ngā wāhi o te kālisiu me ngā wāhi o te fōsifō i ngā tauira pai o te dicalcium phosphate he 21%–23.2% kālisiu me 16.5%–18.5% fōsifō, ā, ko ngā uara whāriki he 23.2% kālisiu me 18.0% fōsifō. Ko te rārangi o te kālisiu ki te fōsifō i te dicalcium phosphate kāore i te whakauru kē me tata ki te 31:40. I tēnā, ahakoa ka taea pea e tētahi tauira kua whakauru kē te whiwhi i tēnei wāhi o te fōsifō, he uaua tonu te whiwhi i tēnei wāhi o te kālisiu i tēnei wā.
