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, 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 thickener, a me ka hana pia.
2. Ma ka ʻoihana ʻoihana, hoʻohana nui ʻia ia i nā mea holoi ma ke ʻano he mea kōkua, kopa synergist a me ka pale ʻana i ke kopa bar mai ka crystallizing a me ka pua ʻana, ka mea hoʻomaʻemaʻe wai ʻenehana, ka mea hoʻomaʻemaʻe ʻili ʻili, ka mea hoʻoheheʻe ʻana, ka mea hoʻomalu aila luawai, ka ʻaila pollution prevention agent no ka hana pepa, calcium disperssion no ka mālama ʻana o ka pena, calcium disperssion no ka mālama ʻana i ka pena. 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 no ka loaʻa ʻana o ka 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 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 i 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 paʻakikī hoʻi e hoʻokō i nā hōʻailona i kuhikuhi ʻia i nā kūlana aupuni.
I kēia manawa, ua aʻo nā kānaka 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. 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.
