wili puʻupuʻu

1.Pehea ka lōʻihi o ke ola lawelawe owili puʻupuʻu?
ʻO ke ola lawelawe o ka galvanizing wela ʻaʻole ia ma lalo o 10 mau makahiki.
2.He aha ke kumu nui opepa galvanized wela?
Pane: hoʻohana nui ʻia ka pepa galvanized wela i ke kūkulu ʻana, nā mea hana hale, nā kaʻa, nā mīkini, nā uila, nā ʻoihana māmā a me nā ʻoihana ʻē aʻe.
3.He aha nā ʻano ʻelua o ka galvanizing wela e like me nā ʻano annealing like ʻole?
Pane: hiki ke hoʻokaʻawale ʻia i ʻelua ʻano: in-line annealing a me waho o ka laina annealing, i kapa ʻia hoʻi ke ʻano pale kinoea a me ke ʻano flux.
4.He aha nā ʻano kila maʻamau o ka pepa galvanized wela?
Pane: nā ʻāpana huahana: coil commodity maʻamau (CQ), pepa galvanized structural (HSLA), kiʻi hohonu kiʻi wela wela (DDQ), bake hardening hot galvanized sheet (BH), pālua ʻāpana kila (DP), TRIP steel (phase transformation induced. kila kila), etc.
5.He aha nā ʻano o ka umu annealing galvanizing?
Pane: aia ʻekolu ʻano o ka umu annealing vertical, kapuahi annealing ākea a me ka umu ahi annealing vertical a me ka paepae.
6.ʻEhia ka nui o nā ʻano hoʻoluʻu no ka hale hoʻomaha?
Pane: ʻelua mau ʻano: ka hoʻoluʻu ʻana i ka ea a me ka hoʻoluʻu wai.
7.He aha nā hemahema nui o ka hot dip galvanizing?
Pane: ʻo ia ka mea nui: hāʻule, ʻōpala, kahi passivation, zinc particle, mānoanoa lihi, ea pahi ʻōpala, ea pahi ʻōpala, hōʻike kila, hoʻokomo ʻia, pōʻino mechanical, hana maikaʻi ʻole o ke kumu kila, wavy lihi, scoop bend, nui mismatch , embossing, zinc layer mānoanoa mismatch, roller printing, etc.
8.He aha nā kumu nui o ka hāʻule ʻana o ka papa zinc?
Pane: ʻo nā kumu nui o ka hāʻule ʻana o ka papa zinc: ka hoʻoheheʻe ʻana o ka ʻili, nā pūhui silika, ka emulsion i hoʻoheheʻe ʻia i ke anuanu, kiʻekiʻe kiʻekiʻe o ka ea a me ka wahi hau hau pale i ka ʻāpana NOF, kūpono ʻole ka ea-wahie ratio, haʻahaʻa hydrogen kahe, oxygen infiltration i loko o ka umu ahi, haʻahaʻa haʻahaʻa haʻahaʻa o ka hao hao e komo ana i ka paila, haʻahaʻa haʻahaʻa pumehana i ka ʻāpana RWP a me ka ea hoʻoheheʻe ma ka puka kapuahi, haʻahaʻa haʻahaʻa wela i ka ʻāpana NOF, lawa ʻole ka ʻaila evaporation, haʻahaʻa haʻahaʻa alumini i loko o ka ipu hao, ʻoi aku ka wikiwiki o ka ʻāpana, ʻaʻole lawa ka emi ʻana ʻO ka manawa noho i loko o ka zinc hoʻoheheʻe he pōkole loa a ʻoi aku ka mānoanoa o ka uhi.
9.He aha nā kumu o ka ʻeleʻele keʻokeʻo a me nā kiko ʻeleʻele?
Pane: hoʻokumu ʻia nā kiko ʻeleʻele e ka hoʻomaʻamaʻa hou ʻana o ka ʻōpala keʻokeʻo. ʻO nā kumu nui o ka rust keʻokeʻo:
Poor passivation, lawa ole a uneven passivation film mānoanoa; ʻAʻole i uhi ʻia ka ʻili me ka ʻaila a i ʻole ka wai ma luna o ka ʻili o ke kila kaula; Aia ka wai ma ka ʻili okāʻei kilai ka wā wili; ʻAʻole maloʻo loa ka passivation; Puu a ua i ka wā o ka lawe ʻana a mālama ʻana paha; He lōʻihi loa ka manawa mālama o nā huahana i hoʻopau ʻia; Hoʻopili ʻia ka pepa galvanized me nā mea ʻino ʻē aʻe e like me ka waikawa a me ka alkali a i mālama pū ʻia paha.
