Pad Puna Ikaika Kiʻekiʻe i Hoʻomaʻemaʻe ʻia

Kiʻi i hōʻike ʻia no ka Spring Pad ikaika kiʻekiʻe i hoʻomaʻemaʻe ʻia

Wehewehe Pōkole:

Ka hoʻohana ʻana i ka mea holoi puna
1. No nā pilina bolt maʻamau, pono e kau ʻia nā mea holoi pālahalaha ma lalo o ke poʻo bolt a me ka nati e hoʻonui i ka wahi e paʻi ai i ke kaomi.
2. No nā ʻōwili a me nā ʻōwili heleuma i hoʻolālā ʻia me nā koi anti-loosening, pono e hoʻohana ʻia ka nati a i ʻole ka mea holoi puna o ka mea anti-loosening, a pono e kau ʻia ka mea holoi puna ma ka ʻaoʻao o ka nati.
3. No nā pilina bolt e hāpai ana i nā ukana hoʻoikaika a i ʻole nā ʻāpana koʻikoʻi, pono e kau ʻia nā mea holoi puna e like me nā koi hoʻolālā, a pono e kau ʻia nā mea holoi puna ma ka ʻaoʻao o ka nati.
4. No nā I-beams a me nā kila kahawai, pono e hoʻohana ʻia nā mea holoi inclined i ka wā e hoʻohana ai i nā pilina mokulele inclined e hana i ka ʻili hali o ka nati a me ke poʻo bolt i kū pololei i ka wili.

1. ʻEleʻele (polū) Hoʻokomo ʻia nā mea hoʻopaʻa e ʻeleʻele ʻia i loko o ka pahu hoʻonā (145±5 °C) o ka sodium hydroxide (NaOH) a me ka sodium nitrite (NaNO2) oxidant e hoʻomehana a hoʻomake, i hiki ai i ka ʻili o ka mea hoʻopaʻa metala ke hana i kahi kiʻiʻoniʻoni ferric tetroxide magnetic (Fe3O4), ʻo ka mānoanoa maʻamau he 0.6-0.8μm, ʻeleʻele a polū-ʻeleʻele paha. Pono ka mālama polū ʻana i nā kūlana HG/20613-2009 a me HG/T20634-2009 no nā mea hoʻopaʻa no nā kīʻaha kaomi.

2. ʻO ka phosphating phosphating kahi hana o ka hopena kemika a me ka electrochemical e hana i kahi kiʻiʻoniʻoni hoʻololi kemika phosphate, a ʻo ka kiʻiʻoniʻoni hoʻololi phosphate i hana ʻia ua kapa ʻia ʻo ia he kiʻiʻoniʻoni hoʻololi phosphate. ʻO ke kumu nui o ka phosphating ʻo ia ka hāʻawi ʻana i ka pale no ka metala kumu a pale i ka metala mai ka palaho ʻana i kekahi ʻano, e hoʻomaikaʻi i ka hiki ke hoʻopili a me ka anti-corrosion o ka papa kiʻiʻoniʻoni pena ma mua o ka pena ʻana, a e hōʻemi i ka friction a me ka lubrication i ke kaʻina hana anu metala. Pono e phosphate ʻia nā stud lua nui no nā ipu kaomi.

3. ʻO ke galvanizing wela-dip ʻO ke galvanizing wela-dip ʻo ia ke hoʻokomo ʻana i nā ʻāpana kila i hoʻoheheʻe ʻia i loko o ka zinc hoʻoheheʻe ʻia i ka mahana kiʻekiʻe ma kahi o 600 °C, i hoʻopili ʻia ka ʻili o nā ʻāpana kila i ka papa zinc, a ʻo ka mānoanoa o ka papa zinc ʻaʻole e emi ma lalo o 65μm no nā papa lahilahi ma lalo o 5mm, a ʻaʻole emi ma lalo o 86μm no nā papa mānoanoa o 5mm a ʻoi aku. I mea e pāʻani ai i ke kumu o ka anti-corrosion.

4. DacrometʻO Dacromet ka unuhi a me ka pōkole o DACROMET, i kapa ʻia ʻo Dacromet, Dacromet, Dicron. Ua kapa ʻia ʻo zinc-chromium coating ma Kina, he ʻano hou ia o ka uhi anticorrosive me ka pauka zinc, ka pauka alumini, ka waikawa chromic a me ka wai deionized ma ke ʻano he mau mea nui. ʻAʻohe pilikia hydrogen embrittlement a maikaʻi ke kūlike o ka torque-preload. Me ka nānā ʻole i nā hopohopo kaiapuni o ka chromium hexavalent, ʻo ia ka mea kūpono loa no nā mea hoʻopaʻa ikaika kiʻekiʻe me nā koi pale corrosion kiʻekiʻe.
