heleuma wili ma ke koʻokoʻo kaulagalvanizing mānoanoa maʻamau

1. ʻO ka mānoanoa kūloko o ka uhi zinc ma ke poʻo a i ʻole ke koʻokoʻo o ka bolt a i ʻole ka wili ʻaʻole e emi iho ma mua o 40um, a ʻo ka mānoanoa awelika i ʻāpono ʻia ʻaʻole i emi iho ma mua o 50um.

2. ʻO ka mānoanoa kūloko o ka uhi zinc ma ka ʻaoʻao ʻē aʻe ma mua o ke poʻo a i ʻole ke koʻokoʻo o ka bolt a i ʻole ka wili ʻaʻole i emi iho ma mua o 20um, a ʻo ka mānoanoa awelika i ʻāpono ʻia ʻaʻole i emi iho ma mua o 30um.

Inā loaʻa i ke kaiapuni hana mea hana i nā koi pilikino no ka hoʻāʻo ʻana i ka paʻakai paʻakai, hiki ke hoʻololi ʻia ka mānoanoa o ka zinc coating i koi ʻia.

ʻO ke kūlana aupuni no ka mānoanoa galvanizing hot-dip he maʻamau i hoʻokumu ʻia e hōʻoia i ka maikaʻi a me ka palekana o nā huahana galvanized wela. Wahi a nā hiʻohiʻona noiʻi like ʻole a me nā koi, ʻo ke kūlana aupuni no ka mānoanoa galvanizing hot-dip e kuhikuhi i nā pae like ʻole o ka mānoanoa papa galvanized.

ʻO ka ʻōlelo maʻamau, ʻo ke kūlana aupuni no ka mānoanoa galvanizing wela e koi i ka mānoanoa papa galvanized ma waena o 20-80 microns. I waena o lākou, ʻo 20 microns ka liʻiliʻi o ka mānoanoa i ʻōlelo ʻia, kūpono no ka anti-corrosion a me nā koi anti-rust, aʻo 80 microns ka mea kūpono no ka ikaika kiʻekiʻe anti-corrosion a me nā koi anti-rust, e like me nā ʻāpana metala o nā mea nui. nā mea e like me nā alahaka a me nā hale.

I ka hana maoli, hiki i nā ʻoihana ke koho i ka mānoanoa galvanized layer kūpono e like me kā lākou pono. Inā ʻaʻole lawa ka mānoanoa o ka galvanized layer, e hoʻopilikia ia i ka hana anti-corrosion a me ka anti-rust o ka huahana, ʻoiai inā he nui ka mānoanoa o ka papa galvanized, e lilo ia i mea ʻeleʻele a maikaʻi ʻole ka ʻili o ka huahana. hoʻonui i nā kumukūʻai hana.
