Ngā Whakamahinga:
1. I roto i te umanga kai, ka whakamahia nuitia hei whakapai ake i te kounga o ngā kai kēne, ngā hua miraka, ngā inu wai hua me te miraka pīni soya; he pupuri wai me te whakangawari mō ngā hua mīti pēnei i te hāmi me te mīti tina; ka taea te pupuri wai, te whakangawari, te whakawhānui me te whakama i te tukatuka o ngā hua wai; ka taea te whakangawari i te kiri o ngā pīni whānui i roto i ngā pīni whānui kēne; ka taea hoki te whakamahi hei whakangawari wai, hei kaihoko chelating, hei kaiwhakahaere PH me te whakamātotoru, tae atu ki te umanga pia.
2. I roto i te mara ahumahi, e whakamahia whānuitia ana i roto i ngā hopi horoi hei kaiāwhina, hei whakakotahi hopi, hei ārai i te tioata me te puāwaitanga o te hopi pae, hei whakangawari wai ahumahi, hei kaiwhakamātao hiako, hei āwhina tae, hei whakahaere paru i te puna hinu, hei ārai i te parahanga hinu mō te hanga pepa, hei whakamarara whai hua mō te maimoatanga o ngā whakatārewatanga pērā i te peita, te kaolin, te konupora waikura, te konupūmā kāponāte, me ētahi atu, me te kaiāwhina tango kapia uku me te whakaiti wai i roto i te umanga uku.
Ko te tikanga whakarite tuku iho o te konutai polyphosphate ko te whakakore i te waikawa phosphoric wera me te wāhanga papatipu o te 75% H3PO4 me te wairewa houra pungarehu hei whiwhi i te paru kua whakakorea me te ōwehenga Na/P o te 5:3, me te pupuri kia mahana i te 70℃~90℃; kātahi ka rehuhia te paru kua riro ki roto i te oumu polymerization kia maroke i te pāmahana teitei, ka whakawhāitihia hei konutai tripolyphosphate i te 400℃ pea. Ehara i te mea ko te waikawa phosphoric wera utu nui anake te mea e hiahiatia ana mō tēnei tikanga tuku iho, engari he nui hoki te kaha wera e pau ana; hei tāpiri, i te wā e whakarite ana i te paru mā te whakakorenga, me whakamahana me te tango i te CO2, ā, he uaua te tukanga. Ahakoa ka taea te whakamahi i te waikawa phosphoric mākū kua purea mā te matū hei whakakapi i te waikawa phosphoric wera hei whakaputa i te konutai tripolyphosphate, nā te nui o te rino whakarewa i roto i te waikawa phosphoric mākū, he uaua ki te whakatutuki i ngā whakaritenga kounga o ngā hua konutai tripolyphosphate o nāianei, ā, he uaua hoki ki te whakatutuki i ngā tohu kua tohua i roto i ngā paerewa ā-motu.
I tēnei wā, kua akohia e te tangata ētahi tukanga whakaputa hou o te konutai tripolyphosphate, pērā i te tono patent Haina Nama 94110486.9 "He tikanga mō te whakaputa konutai tripolyphosphate", Nama 200310105368.6 "He tukanga hou mō te whakaputa konutai tripolyphosphate", Nama 200410040357.9 "He tikanga mō te whakaputa konutai tripolyphosphate mā te tikanga whānui maroke-mākū", Nama 200510020871.0 "He tikanga mō te whakaputa konutai tripolyphosphate mā te tikanga wehewehenga tote takirua a Glauber", 200810197998.3 "He tikanga mō te whakaputa konutai tripolyphosphate me te whakaputa taha-ā-amonium chloride", me ētahi atu; ahakoa he āhuatanga motuhake ēnei otinga hangarau, ko te nuinga o ēnei he whakarerekē i ngā rauemi mata whakakorekore.
Tikanga mō te whakaputa i te konutai tripolyphosphate mā te whakamahi i te konutai pyrophosphate mata
Ka tomo tuatahi te konutai pyrophosphate mata ki te tāke horoi tote hei tango i te nuinga o te konutai pūhaumāota, kātahi ka tomo ki te mīhini tātari pereti me te anga mō te tātari tuatahi. He nui te konutai pyrophosphate kei roto i te keke tātari, ā, ko te kukū papatipu o te konutai pūhaumāota he iti iho i te 2.5%. Kātahi ka whakamahanahia te otinga ki te 85°C i roto i te tāke whakarewa me te mamaoa hei whakaoho me te whakarewa. Ka tāpirihia te konutai sulfide i te wā whakarewa hei tango i ngā katote konganuku. Ko te mea kore e whakarewa ko ngā poke pēnei i te parahi hauwai. Ka tātarihia anō mō te wā tuarua. Ko te tātari he otinga konutai pyrophosphate. Ka tāpirihia te waro whakahohe ki te tātari hei tango i ngā tae, ka tāpirihia te waikawa phosphoric hei whakakawa me te whakateretere i te whakarewatanga, ā, i te mutunga ka tāpirihia te kawakore wai hei whakatika i te uara pH ki te 7.5-8.5 hei whakarite i tētahi wai kua whakapaia.
Ka whakamahia tika tētahi wāhanga o te wai kua oti te whakamātao i roto i te wāhanga whakarite wai whakapūmau konutai tripolyphosphate, ā, ka panahia tētahi atu wāhanga o te wai kua oti te whakamātao ki roto i te tioata DTB. Ka whakamataohia te wai kua oti te whakamātao i roto i te tioata DTB i roto i te whakawhiti wera mā te papu tohanga ā-kaha me te wai 5°C e tukuna ana e te pouaka whakamatao. Ina heke te pāmahana o te otinga ki te 15°C, ka whakapūmautia hei para, kātahi ka haria ki te tāke taumata-teitei, ka tukuna ki roto i te taiwhanga whakamātao hei wehe i te taiwhanga whakamātao kia whiwhi ai i ngā tioata konutai pyrophosphate. Ka tāpirihia ngā tioata konutai pyrophosphate ki te wāhanga whakarite wai whakapūmau i roto i te tukanga hanga konutai tripolyphosphate, ā, ka konatunatua ki te waikawa phosphoric me te wai houra caustic hei whakarite i te wai whakapūmau hei rauemi mata mō te hanga konutai tripolyphosphate. Ka whakahokia te wai tote kua whakahuatia ake nei ki te horoi i te konutai pyrophosphate mata; ina tae te ihirangi konutai pūhaumāota i roto i te wai tote ki te mātotoru, ka panahia te wai tote ki roto i te tāke ārai, ā, ka panahia te wai tote i roto i te tāke ārai ki roto i te koti paipa hau hiku konutai tripolyphosphate hei whakawhiti wera me te hau hiku pāmahana-tiketike. I muri i te whakawhiti wera, ka hoki te wai tote ki te tāke ārai mō te mimiti.
