Tuairisgeul toraidh
Tha HDG mar as trice a’ toirt iomradh air galvanachadh teth-dip. Is e galvanachadh hot-dip toirt air a’ mheatailt leaghte freagairt leis a’ mhaitrix iarainn gus còmhdach alloy a thoirt gu buil, gus am bi am matrix agus an còmhdach air an cur còmhla. Is e galvanachadh teth-dip na pàirtean iarainn is stàilinn a phioc an toiseach, gus an ocsaid iarainn a thoirt air falbh air uachdar na pàirtean iarainn is stàilinn, às deidh picilte, thèid a ghlanadh ann an tanca de ammonium chloride no sinc chloride fuasgladh uisgeach no fuasgladh uisgeach measgaichte de ammonium chloride agus sinc chloride, agus an uairsin a chuir chun tanca còmhdach dip teth. Tha na buannachdan aig galvanachadh hot-dip airson còmhdach èideadh, gèilleadh làidir agus beatha seirbheis fhada.
