ʻIke ʻia ka huahana maʻemaʻe e like me nā kristal keʻokeʻo, ʻoiai ʻo ka papa ʻoihana he wai aniani ʻole a melemele palupalu. He maʻalahi ia e hoʻoheheʻe ʻia i ka wai, methanol a me ka ethanol. ʻO ka 1-Hydroxyethane-1,1-diphosphonic acid kahi mea maka kemika, i hoʻohana pinepine ʻia i ka mālama wai ʻoihana, nā huahana hoʻomaʻemaʻe hale a me nā huahana mālama pilikino.

Hoʻohana
ʻO kēia huahana ka mea nui no ka electroplating cyanide-free. Ke hoʻohui ʻia i loko o kahi hopena electroplating keleawe cyanide-free, hiki iā ia ke kau pololei i nā papa keleawe ma luna o nā mea sodium-iron me ka hoʻopili maikaʻi loa. Loaʻa i ka uhi kahi ʻili laumania a me ka ʻōlinolino kala maikaʻi. ʻO ka nui o ka hopena o ka hopena 60% he 100 a 120 ml i ka lita, a ʻo ka nui o ke keleawe sulfate he 15 a 20 gram i ka lita. Eia kekahi, ʻo ka hoʻoluʻu ʻana i nā ʻāpana i uhi ʻia i loko o kahi hopena 1% a 2% o kēia huahana e hoʻāla i ko lākou ʻili ma mua o ka electroplating hiki ke hoʻonui hou i ka hopena electroplating.
ʻO ka Hydroxyethylidene Diphosphonic Acid (HEDP) kahi ʻano hou o ka mea hoʻohuihui electroplating chlorine-free. Hana ia ma ke ʻano he mea hoʻopaʻa maikaʻi wai nui i nā ʻōnaehana wai hoʻoluʻu e kaʻapuni ana a hana i ka pale ʻana i ka pala a me ka pale ʻana i ka unahi. ʻO ia kekahi o nā mea mālama wai polyphosphonic acid organik. Aia kekahi mau huahana ʻē aʻe i hana ʻia ma ka home o kēia ʻano, e like me Amino Trimethylene Phosphonic Acid (ATMP) me ke ʻano \([CH_2PO(OH)_2]_3N\), Ethylene Diamine Tetra Methylene Phosphonic Acid (EDTMP), a me nā mea hou aku.
ʻO nā waikawa polyphosphonic organik kahi māhele o nā mea hoʻōla wai i hoʻomohala ʻia i ka hopena o nā makahiki 1960 a ua ʻike ʻia a puni nā makahiki 1970. ʻO ka puka ʻana mai o kēia mau mea hana i hoʻomohala nui i ka ʻenehana hoʻōla wai. Ke hoʻohālikelike ʻia me nā polyphosphates inorganic, loaʻa i nā waikawa polyphosphonic organik ke kūpaʻa kemika maikaʻi loa, ke kū'ē ʻana i ka hydrolysis, ke ahonui wela kiʻekiʻe, ka dosage haʻahaʻa, a me ka hana pale ʻana i ka palaho a me ka unahi.
Hana lākou ma ke ʻano he mau mea hoʻopale i ka palaho cathodic a me nā mea hoʻopale unahi non-stoichiometric. Ke hui pū ʻia me nā mea hana wai ʻē aʻe, hāʻawi lākou i nā hopena synergistic i makemake ʻia. Hōʻike lākou i ka hiki ke chelating koʻikoʻi i nā ion metala he nui e like me ka calcium, magnesium, keleawe a me ka zinc, a loaʻa pū kekahi mau hopena deactivation maikaʻi i nā paʻakai inorganic o kēia mau metala e like me ka calcium sulfate (\(CaSO_4\)), calcium carbonate (\(CaCO_3\)) a me ka magnesium silicate (\(MgSiO_3\)). No laila, ua hoʻohana nui ʻia lākou i ka ʻenehana mālama wai.
Mea hoʻohui phosphorylation no ka serine a me ka pyranose i pale ʻia.
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
