Aluminum profiles powder spray coating line

ʻO ka uhi ʻana i ka pauka me ka hoʻohana ʻana i ke kumu o ka hoʻoheheʻe electrostatic o ka adsorption pauka maloʻo ma nā ʻaoʻao alumini metala, ma hope o 200 ℃ barbecue wela kiʻekiʻe, hoʻōla ʻia ka pauka i kahi papa o kahi 60 microns mānoanoa paʻa paʻa paʻa. E hoʻomaʻamaʻa i ka ʻili o ka huahana a me ka waihoʻoluʻu me ke kūpaʻa ikaika o ka waika, ka pale alkali, ka pale ʻana i ka hopena, ke kūpaʻa ʻana, hiki ke pale i ka radiation ultraviolet ikaika a me ka ua ʻana o ka ua waika no ka manawa lōʻihi, ʻaʻole ʻike ʻia ka uhi ʻana o ka chalking, mae, peeling a me nā mea ʻē aʻe. He 30 mau makahiki ke ola o ka pauka i uhi ʻia i ka alumini ma lalo o nā kūlana maʻamau. ʻO kona uhi ʻana i ka ʻili i loko o 5-10 mau makahiki e hōʻoia ʻaʻole e mae ke kala, ʻaʻole e hoʻololi i ke kala, ʻaʻole e pohā. ʻOi aku ka maikaʻi o kona pale ʻana i ka wā a me ka corrosion ma mua o ke ʻano like ʻole o ka waihoʻoluʻu alumini.

Hoʻouka → Hoʻomaʻamaʻa mua → Hoʻomaloʻo ʻana i ka wai → Hoʻomaʻalili → Hoʻomoʻi ʻana i ka pauka (Reciprocator) → Hoʻōla ʻia i ka pauka (ka ea wela) → Hoʻoluʻu → Unloading

ʻO ka maikaʻi o ke kaʻina hana mua e pili pono i ka maikaʻi o ka kiʻiʻoniʻoni pauka, ʻaʻole maikaʻi ka mālama mua ʻana, e maʻalahi ai ka ʻili ʻana i ke kiʻiʻoniʻoni, ʻūhū a me nā mea ʻē aʻe.

Hiki ke hoʻohana ʻia ke ʻano hoʻomaʻamaʻa kemika no nā ʻāpana stamping sheet metala. ʻO ka hapa nui o ka ʻōpala a i ʻole ka ʻili o ka mea hana mānoanoa, ka hoʻohana ʻana i ka sandblasting, ka puhi ʻana i ka pana a me nā ʻano hana ʻē aʻe e wehe ai i ka ʻōpala, akā ʻo ka descaling mechanical pono e hōʻoia i ka maʻemaʻe o ka ʻili o ka mea hana.

E like me ke kiʻekiʻe o nā hemahema o ka mea hana e ʻoki ana i ka putty conductive, ma hope o ka hoʻomaloʻo ʻana me ka sandpaper wili mālie, hiki iā ʻoe ke hana i ke kaʻina hana aʻe.

Inā loaʻa kekahi mau ʻāpana o ka mea hana ʻaʻole pono i ka uhi ʻana, hiki ke uhi ʻia me ka mea hoʻopili pale, a me nā mea ʻē aʻe, ma mua o ka hoʻomehana ʻana e pale ai i ka pīpī ʻana i ka uhi.

ʻAʻole koi ʻia ka preheating. Inā makemake ʻia kahi uhi mānoanoa, hiki ke hoʻomaʻamaʻa ʻia ka mea hana i 100-160 ℃, hiki ke hoʻonui i ka mānoanoa o ka uhi.

Electrostatic generator ma o ka pū pū o ka electrode needle i ka workpiece kuhikuhi o ka hakahaka e hoʻokuʻu kiʻekiʻe-voltage electrostatic (negative), ka kiʻekiʻe-voltage electrostatic mai ka pū pu o ka pauda a me ka compressed ea hui like me ka electrode a puni ka ea ionization (negative charge). ʻO ka mea hana ma o nā hangers ma o ka conveyor link ground (grounding pole), i mea e hana ai ka pū a me ka mea hana i kahi māla uila ma waena o ka pauka i loko o ka ikaika o ka uila a me ke kaomi ʻana i ka ea ma lalo o ka pahu pālua i ka ʻili o ka mea hana. e hilinaʻi ana i ka huki ʻana i ka electrostatic ma luna o ka ʻili o ka mea hana e hana i kahi papa o ka uhi ʻaʻahu.

Ma hope o ka pīpī ʻana i ka mea hana ma o ke kaulahao conveyor i loko o ka 180 ~ 200 ℃ hoʻomehana lumi kuke, a mālama i ka mahana no kahi manawa kūpono, (15-20 mau minuke) i hiki ai i ka hoʻoheheʻe ʻana, pae, hoʻōla, i mea e loaʻa ai ka hopena o ka papa hana. makemake. (He ʻokoʻa nā pauka ʻokoʻa i ka mahana kuke a me ka manawa). ʻO kēia ka mea e pono ai mākou e makaʻala i ka hana hoʻōla.

Ma hope o ka ho'ōla ʻia ʻana o ka uhi, wehe i ka pale a ʻoki i nā burrs.

Ma hope o ka ho'ōla ʻana i ka mea hana, ʻo ka nānā nui ʻana i kēlā me kēia lā o ka hiʻohiʻona (inā maʻemaʻe a ʻālohilohi paha, me ka ʻole a i ʻole nā ​​​​particle, shrinkage a me nā hemahema ʻē aʻe) a me ka mānoanoa (ka mana ma 55 ~ 90μm). No nā hemahema i ʻike ʻia e like me ka leakage, pinhole, bruise, bubble, etc., e hoʻoponopono hou ʻia ka mea hana.

Ma hope o ka nānā ʻana, hoʻokaʻawale ʻia nā huahana i hoʻopau ʻia a waiho ʻia i loko o ke kaʻa kaʻa a me ka pahu hoʻololi, a hoʻokaʻawale ʻia mai kekahi i kekahi e nā mea hoʻopili palupalu e like me ka pepa pahu a me ke kiʻi ʻoniʻoni e pale ai i nā ʻōpala a me ka abrasion.
