Pehea e hōʻoiaʻiʻo ai i ka maikaʻi o ka pā uea wela

1,uwea hoʻopaʻa welahana ʻia me ke kila kila haʻahaʻa haʻahaʻa haʻahaʻa kiʻekiʻe, hana ʻia me ke kila kalapona haʻahaʻa kiʻekiʻe, ma hope o ke kaha kiʻi ʻana, pickling rust removal, kiʻekiʻe wela annealing, hot dip galvanizing, cooling a me nā hana ʻē aʻe.Hiki ke hoʻohana ʻole ka papa insulation o nā huahana insulation paʻakikī.16 ~ 18 uʻa uʻi puʻupaʻa pālua ʻia, ʻaʻole pono e ʻoi aku ka nui ma mua o 400mm.Eia nō naʻe, pono e hui pū ʻia nā paipu a i ʻole nā ​​​​mea hana like me ke anawaena nominal like a ʻoi aku paha ma mua o 600mm a hoʻoikaika ʻia me nā uwea hao galvanized no.10 a no.14 a i ʻole ka hoʻopaʻa ʻana i nā kāʻei kila me kahi ākea o 500mm.

2, semi-paʻakikī a me ka palupalu insulation insulation papa, e like me ke anawaena o ka paipu a me ka nui o ka lako, ka hoʻohana 'ana i ka pahu kila kāʻei, no.14 ~ 16uwea hao haoa i ʻole ka laulā o 60mm lipine hoʻopili no ka hoʻopaʻa ʻana.ʻAʻole pono e ʻoi aku ka nui o nā huahana insulation semi-rigid ma mua o 300mm;No ka manaʻo palupalu, ʻaʻole pono ka papa ma mua o 200mm.

3, i mea euwea hao haoma ka ili o ka papa sedimentary a hiki i ka wehe 'ana o ka papa kiʻiʻoniʻoni ili, hiki ke loaʻa a mālama ʻia e ka ʻenehana maʻamau;Hoʻokumu ʻia ka huʻa i ka wā e lawe ʻia ai ke kopa a me nā surfactants e like me nā momona saponified i loko o ka pahu.ʻAʻole pōʻino paha nā helu haʻahaʻa o ka hoʻokumu ʻana i ka huʻa.ʻO ka hiki ʻana mai o nā ʻāpana liʻiliʻi like ʻole o ka denier nui i loko o ka pahu e hiki ke hoʻopaʻa i ka ʻāpana ʻōpala, akā hiki i ka hōʻiliʻili ʻana o nā ʻāpana paʻa nui ke kumu i ka pahū.

4, me ka moena kalapona i ho'ā 'ia e wehe i nā mea 'eleu ili.A i ʻole ma o kāna kānana ʻana e hana i ka ʻūhā ʻaʻole paʻa loa, ʻo ia nā ana kūpono;Pono e hana ʻia nā hana ʻē aʻe e hōʻemi i ka hoʻokomo ʻana o ka surfactant.Hiki ke hoʻemi ʻia ka wikiwiki electroplating e ka hoʻohui ʻana i nā mea organik.ʻOiai e hoʻomaʻamaʻa ana nā mea hoʻoheheʻe kemika i nā helu deposition kiʻekiʻe, ʻaʻole i kūpono ka waiho ʻana o nā mea organik i nā koi o ka mānoanoa o ka uhi ʻana, no laila hiki ke hoʻohana ʻia ke kalapona hoʻāla e mālama i ka ʻauʻau.
