Ko te hua parakore he rite ki ngā tioata mā, ko te hua ahumahi ia he wai mārama, he kore tae, he kōwhai mā. He ngāwari te wairewa ki te wai, ki te methanol me te ethanol. Ko te waikawa 1-Hydroxyethane-1,1-diphosphonic he matū mata, e whakamahia whānuitia ana i roto i te maimoatanga wai ahumahi, ngā hua horoi whare me ngā hua tiaki whaiaro.

Whakamahinga
Ko tēnei hua te rauemi matua mō te whakakikorua hiko kore-cyanide. Ina hangaia ki roto i te otinga whakakikorua parahi kore-cyanide, ka taea e ia te whakakikorua tika i ngā paparanga parahi ki runga i ngā rauemi konutai-rino me te piri pai. He maeneene te mata o te paninga me te kanapa o te tae. Ko te horopeta whānui o te otinga 60% ihirangi he 100 ki te 120 ml ia rita, ā, ko te horopeta o te konukura whanariki he 15 ki te 20 karamu ia rita. Hei tāpiri, mā te rumaki i ngā wāhanga whakakikorua ki roto i te otinga 1% ki te 2% o tēnei hua hei whakahohe i tō rātou mata i mua i te whakakikoruatanga ka taea te whakarei ake i te pānga whakakikorua.
Ko te Waikawa Diphosphonic Hydroxyethylidene (HEDP) he momo hou o te matū whakakōpiri hiko kore-hauora. Koia te mea matua hei whakaū i te kounga wai i roto i ngā pūnaha wai whakamatao e rere ana, ā, he mahi anō hoki hei aukati i te waikura me te ārai i te unahi. Ko tētahi o ngā matū maimoatanga wai waikawa polyphosphonic waro. He atu hua hanga-ā-rohe anō hoki o tēnei momo, pērā i te Waikawa Phosphonic Amino Trimethylene (ATMP) me te tauira \([CH_2PO(OH)_2]_3N\), te Waikawa Phosphonic Ethylene Diamine Tetra Methylene (EDTMP), me ētahi atu.
Ko ngā waikawa polyphosphonic waro he kāwai o ngā kaihoko maimoatanga wai i whakawhanakehia i te mutunga o te tekau tau atu i 1960, ā, i mōhiotia i te tekau tau atu i 1970. Nā te putanga mai o ēnei kaihoko i tino whakaneke ake te hangarau maimoatanga wai. Ki te whakatauritea ki ngā polyphosphates inorganic, he pai te pumau matū o ngā waikawa polyphosphonic waro, he ātete ki te waikura, he manawanui ki te pāmahana teitei, he iti te horopeta, me te mahi aukati waikura me te unahi.
He aukati waikura katote ēnei, he aukati tauine kore-stoichiometric hoki. Ina honoa ki ētahi atu kaihoko maimoatanga wai, ka puta he pānga honohono e hiahiatia ana. He kaha chelating tino pai ki ngā katote konganuku maha tae atu ki te konupūmā, te konupora, te parahi me te konutea, ā, he pai hoki ngā pānga whakakore i ngā tote kore-waro o ēnei konganuku pērā i te konupūmā whanariki (\(CaSO_4\)), te konupūmā kāponāte (\(CaCO_3\)) me te konupora silicate (\(MgSiO_3\)). Nō reira, he whānuitia te whakamahinga o ēnei i roto i te hangarau maimoatanga wai.
He matū whakapūkawai mō te serine me te pyranose kua tiakina.
Te Tākai me te Tukunga
25KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Nō ngā taonga noa, ā, ka taea te tuku mā te moana me te rangi
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
