Pono: ʻO ka pauka keʻokeʻo a i ʻole granules, hiki ke hoʻoheheʻe ʻia i ka wai. E like me ka noi a me ka hoʻoponopono koi ʻana, hiki iā mākou ke hāʻawi i nā huahana o nā kikoʻī like ʻole e like me nā ʻano like ʻole (0.5-0.9g / cm3), nā mea hoʻonā like ʻole (10g, 20g / 100ml wai), sodium tripolyphosphate koke, nui-particle sodium tripolyphosphate, etc.
Hoʻohana:
1. I ka ʻoihana meaʻai, hoʻohana nui ʻia e like me ka hoʻomaikaʻi ʻana i ka maikaʻi no ka meaʻai canned, nā huahana waiu, nā mea inu wai a me ka waiū soy; he mea hoʻopaʻa wai a ʻoluʻolu no nā huahana ʻiʻo e like me ka ʻiʻo ham a me ka ʻai awakea; hiki iā ia ke mālama i ka wai, hoʻomāmā, hoʻonui a bleach i ka hana ʻana i nā huahana wai; hiki iā ia ke hoʻonāwaliwali i ka ʻili o nā pīni ākea i loko o nā pīni ākea; hiki ke hoʻohana 'ia e like me ka wai softener, chelating agent, PH regulator a me ka mānoanoa, a me ka hana pia.
2. Ma ka ʻoihana ʻoihana, hoʻohana nui ʻia ia i nā detergents ma ke ʻano he mea kōkua, kopa synergist a me ka pale ʻana i ka kopa bar mai ka crystallizing a me ka pua ʻana, ka mea hoʻomaʻemaʻe wai ʻoihana, ka mea hoʻomaʻemaʻe i ka ʻili, ka mea hoʻoheheʻe ʻia, ka mea hoʻomalu lepo ʻaila, ka ʻaila pollution prevention. ka mea hana no ka hana pepa, ka dispersant maikaʻi no ka mālama ʻana i nā mea hoʻomaha e like me ka pena, kaolin, magnesium oxide, calcium carbonate, a me nā mea ʻē aʻe, a me ka mea hana degumming ceramic a me ka mea hoʻemi wai i ka ʻoihana ceramic.
ʻO ke ʻano hoʻomākaukau kuʻuna o ka sodium polyphosphate e hoʻokaʻawale i ka waika phosphoric wela me ka hapa nui o 75% H3PO4 me ka hoʻokuʻu ʻana i ka lehu soda e loaʻa ai kahi slurry neutralized me ka ratio Na / P o 5:3, a mālama i ka mahana ma 70 ℃ ~ 90 ℃; a laila e pīpī i ka slurry i loaʻa i loko o ka umu polymerization no ka dehydration ma ke kiʻekiʻe wela, a condense i loko o ka sodium tripolyphosphate ma kahi o 400 ℃. ʻAʻole pono kēia ʻano hana kuʻuna i ka waika phosphoric wela, akā hoʻopau pū i ka ikehu wela; Eia kekahi, i ka hoʻomākaukau ʻana i ka slurry ma ka neutralization, pono e wela a wehe i ka CO2, a paʻakikī ke kaʻina hana. ʻOiai hiki ke hoʻohana ʻia ka waika phosphoric pulu i hoʻomaʻemaʻe ʻia e hoʻololi i ka waika phosphoric wela e hana i ka sodium tripolyphosphate, ma muli o ke kiʻekiʻe o ka hao hao i loko o ka wai phosphoric wai, paʻakikī ke hoʻokō i nā koi o nā huahana sodium tripolyphosphate o kēia manawa, a ʻo ia hoʻi. paʻakikī ke hoʻokō i nā hōʻailona i hōʻike ʻia ma nā kūlana aupuni.
I kēia manawa, ua aʻo ka poʻe i kekahi mau kaʻina hana hou o ka sodium tripolyphosphate, e like me ka noi patent Kina No. 94110486.9 "He ala no ka hana ʻana i ka sodium tripolyphosphate", No. no ka hana ʻana i ka sodium tripolyphosphate ma ke ʻano holoʻokoʻa maloʻo", No. 200510020871.0 "He ala no ka hana ʻana i ka sodium tripolyphosphate e ka Glauber's salt double decomposition method", 200810197998.3 "He ala no ka hana ʻana i ka sodium tripolyphosphate a me ka hana ʻana i ka ammonium chloride", etc.; ʻOiai he mau hiʻohiʻona ko kēia mau ʻenehana ʻenehana, ʻo ka hapa nui o lākou e hoʻololi i ka neutralization raw material.
ʻO ke ala no ka hana ʻana i ka sodium tripolyphosphate me ka hoʻohana ʻana i ka sodium pyrophosphate
Komo mua ka sodium pyrophosphate i loko o ka pahu holoi paʻakai no ka wehe ʻana i ka hapa nui o ka sodium chloride, a laila komo i ka pā a me ka papa kānana kaomi no ka kānana mua. Aia i loko o ka keke kānana ka nui o ka sodium pyrophosphate, a ʻo ka nui o ka sodium chloride ma lalo o 2.5%. A laila, hoʻomehanaʻia ka hopena i 85 ° C i loko o ka pahu dissolution me ka mahu no ka hoʻouluʻana a me ka hoʻoheheʻe. Hoʻohui ʻia ka sodium sulfide i ka wā e hoʻoheheʻe ʻia e wehe i nā ion metala. ʻO ka mea hiki ʻole ke hoʻoheheʻe ʻia e like me ka copper hydroxide. Ua kānana hou ʻia no ka lua o ka manawa. ʻO ka kānana he hopena sodium pyrophosphate. Hoʻohui ʻia ke kalapona i hana ʻia i ka kānana e wehe i nā puaʻa, hoʻohui ʻia ka phosphoric acid e hoʻoheheʻe ʻia a hoʻolalelale i ka hoʻoheheʻe ʻana, a hoʻohui ʻia ka alkali wai e hoʻoponopono i ka waiwai pH i 7.5-8.5 e hoʻomākaukau ai i kahi wai hoʻomaʻemaʻe.
Hoʻohana pololei ʻia kahi ʻāpana o ka wai i hoʻomaʻemaʻe ʻia i ka ʻāpana sodium tripolyphosphate neutralization wai hoʻomākaukau, a ʻo ka ʻāpana ʻē aʻe o ka wai i hoʻomaʻemaʻe ʻia e hoʻoheheʻe ʻia i loko o ka crystallizer DTB. ʻO ka wai i hoʻomaʻemaʻe ʻia i loko o ka DTB crystallizer e hoʻoluʻu ʻia i loko o ka mea hoʻololi wela e ka pume kaʻa kaʻa a me ka wai 5 ° C i hoʻouna ʻia e ka chiller. Ke hāʻule ka mahana hoʻonā i 15 ° C, ua crystallized i loko o nā flocs a laila lawe ʻia i ka pahu kiʻekiʻe kiʻekiʻe a centrifuged i loko o ka centrifuge no ka hoʻokaʻawale centrifugal e loaʻa ai nā kristal sodium pyrophosphate. Hoʻohui ʻia nā crystals sodium pyrophosphate i ka ʻāpana hoʻomākaukau wai neutralization i ke kaʻina hana hana sodium tripolyphosphate a hui pū ʻia me ka waikawa phosphoric a me ka soda caustic wai e hoʻomākaukau ai i ka wai neutralization e like me ka mea maka no ka hana ʻana o ka sodium tripolyphosphate. Hoʻihoʻi ʻia ka brine i ʻōlelo ʻia ma luna e holoi i ka sodium pyrophosphate maʻemaʻe; ke hiki i ka saturation ka nui o ka sodium chloride i loko o ka brine, hoʻomoʻi ʻia ka brine i loko o ka pahu paʻa, a ʻo ka brine i loko o ka pahu hoʻopaʻa e hoʻomoʻi ʻia i loko o ka pahu pahu pahu pahu pahu sodium tripolyphosphate huelo e hoʻololi i ka wela me ke kinoea huelo kiʻekiʻe. Hoʻi ka brine ma hope o ka hoʻololi ʻana i ka wela i ka pahu pale no ka hoʻoheheʻe ʻana.
