No ka mālama ʻana i ka pahu holoi wai hydrochloric, ʻo ka mea nui ka mālama ʻana i ka manawa pickling a me ke ola o ka pahu pickling, i mea e hōʻoia ai i ka huahana kiʻekiʻe a me ke ola lawelawe o ka pahu pickling.
No ka loaʻa ʻana o ka hopena pickling maikaʻi loa, pono e hoʻomalu mua ʻia ka neʻe ʻana o ka waika hydrochloric, a laila e hoʻomalu ʻia ka ʻike o nā ion hao (paʻakai hao) i loko o ka hopena pickling.No ka mea, ʻaʻole wale ka hopena o ka waikawa e hoʻopili i ka hopena pickling o ka mea hana, akā ʻo ka ʻike o nā ion hao e hōʻemi i ka hapa nui o ka hopena pickling, e hoʻopilikia pū i ka hopena pickling a me ka wikiwiki o ka mea hana.He mea pono e hoʻomaopopo i ka loaʻa ʻana o ka maikaʻi pickling maikaʻi loa, pono pū ka hopena pickling i kahi nui o nā ion hao.
(1)ʻO ka manawa pilahi
ʻO ka ʻoiaʻiʻo, ʻo ka manawa pickling e pili ana i ka neʻe ʻana o ka waika hydrochloric / iron iron (paʻakai hao) a me ka mahana o ka hopena pickling.
ʻO ka pilina ma waena o ka manawa pickling a me ka zinc content:
He mea kaulana ia i nā hana galvanizing wela, ʻo ka hoʻohana ʻana i ka overpickling pale o nā mea hana galvanized e hoʻonui ai i ka hoʻouka zinc, ʻo ia hoʻi ka "overpickling" e hoʻonui i ka ʻai zinc.
Ma keʻano holoʻokoʻa, ʻo ka hoʻokomo ʻana i loko o ka pahu pickling no 1 hola ua lawa ia e hoʻopau loa i ka ʻōpala.I kekahi manawa, ma lalo o nā kūlana hana o ka hale hana, hiki ke waiho ʻia ka mea hana i hoʻopaʻa ʻia i loko o ka pahu pickling i ka pō, ʻo ia hoʻi, ka hoʻolulu ʻana no 10-15 mau hola.Hoʻopili ʻia kēlā mau mea hana galvanized me ka zinc ʻoi aku ma mua o ka pickling manawa maʻamau.
(2)ʻOi loa ka Pickling
ʻO ka hopena pickling maikaʻi loa o ka mea hana i ka wā e hiki ai ka neʻe ʻana o ka waika hydrochloric a me ka neʻe ʻana o nā ion hao i hoʻokahe ʻia (nā paʻakai hao) i kahi kaulike pili.
(3)Ke ala hoʻoponopono no ka emi ʻana o ka hopena waikawa
Ke emi a nalowale ka hopena pickling ma muli o ka saturation o nā ion hao (paʻakai hao), hiki ke hoʻoheheʻe ʻia me ka wai e hoʻihoʻi i ka hana pickling.ʻOiai ua hoʻemi ʻia ka manaʻo o ka waika hydrochloric, hiki ke hoʻokō ʻia ka hana pickling, akā ʻoi aku ka lohi.Inā hoʻohui ʻia kahi ʻakika hou i loko o ka ʻaila pickling me ka mea hao saturated, e hāʻule ka neʻe ʻana o ka wai holoi wai hydrochloric hou ma luna o ke kiko saturation, a ʻaʻole hiki i ka pickling o ka mea hana.
(4)Hana ʻia ka mālama ʻana ma hope o ka emi ʻana o ka solubility acid
Ke hoʻohana ʻia ka hopena pickling no kekahi manawa, e emi ana kona neʻe ʻana a lilo hoʻi i ka wai ʻona.Eia naʻe, ʻaʻole hiki ke hoʻihoʻi ʻia ka waikawa i kēia manawa e ka mea hana, a ke paʻa nei i kekahi waiwai no ka hoʻohana.I mea e hoʻohana ai i ka waikawa haʻahaʻa me ka hoʻohaʻahaʻa haʻahaʻa, i kēia manawa, ʻo nā mea hana i loaʻa i ka leakage plating kūloko i ka hot-dip galvanizing a pono e hou hou ʻia ke kau ʻia ma waena o lākou, ʻo ka pickling a me ka reprocessing kekahi mea hoʻohana maikaʻi. ʻakika ʻōpala.
ʻO ke ʻano no ka hoʻololi ʻana i ka ʻakika kahiko me ka hydrochloric acid pickling solution:
Ke ʻoi aku ka paʻakai hao i loko o ka waika kahiko ma mua o ka mea i ʻōlelo ʻia, pono e hoʻololi ʻia me ka waikawa hou.ʻO ke ʻano o ka waika hou he 50%, hoʻohui ʻia ka waikawa kahiko i ka waikawa hou ma hope o ka ua, a ʻo ka nui o ka waikawa kahiko he ~ 50%.Hiki i nā paʻakai hao me ka liʻiliʻi ma lalo o 16% ke hoʻonui i ka hana o ka hopena pickling, ʻokoʻa ia mai ka acid sparse, a mālama pū i ka nui o ka waikawa.
Eia nō naʻe, ma kēia ʻano, me ka holomua o ka ʻenehana galvanizing wela, pono e hoʻokō ʻia ka nui o ka waika kahiko i hoʻohui ʻia ma ke kumu o ka hoʻomalu pono ʻana i ka ʻike o ka paʻakai hao o ka waika kahiko, a me ka neʻe ʻana o ka paʻakai hao i ka paʻakai hou. Pono e ho'omalu 'ia ka ho'onā waika hydrochloric i ho'omākaukau 'ia i loko o ka poho lima.I loko o ka laulā, ʻaʻole pono ʻoe e hahai makapō i kekahi mau waiwai.
Mea kila mea hana a me ka wikiwiki pickling
ʻOkoʻa ka wikiwiki o ka pickling me ka haku ʻana o ka mea hana kila pickled a me ka unahi hopena.
ʻO ka maʻi kalapona i loko o ke kila he mana nui i ka helu hoʻoheheʻe o ka matrix kila.ʻO ka hoʻonui ʻana o ka maʻi kalapona e hoʻonui koke i ka dissolution rate o ka matrix kila.
Hoʻonuiʻia ka hoʻoheheʻeʻana o ka matrix workpiece kila ma hope o ke anu a me ka wela;ʻoiai e emi ana ka helu hoʻoheheʻe ʻana o ka mea hana kila ma hope o ka annealing.Ma ka pālākiō hao ma ka ʻili o ka mea hana kila, ʻoi aku ka nui o ka dissolution o ka hao monoxide ma mua o ka ferric oxide a me ka ferric oxide.ʻOi aku ka nui o ka hao monoxide ma mua o nā ʻāpana hao i hoʻopaʻa ʻia.No laila, ʻoi aku ka wikiwiki o kāna pickling speed.ʻO ka mānoanoa o ka ʻili hao hao, ʻoi aku ka lōʻihi o ka manawa pickling.Inā ʻaʻole like ka mānoanoa o ka pālākiō hao, maʻalahi ka hana ʻana i nā hemahema ma lalo o ka pickling a i ʻole over-pickling.
