Kau ʻia ma 2018-01-08He mea koʻikoʻi ko Zinc flake coating mea hana i ka ʻoihana hou, zinc flake coating application i ka hana ʻana he mea maʻamau, akā ʻaʻole hiki ke mālama ʻia ka zinc flake i ke kiʻekiʻe wela, ʻo ia ke kumu?
Ma muli o ka maʻalahi o ka wela kiʻekiʻe e hoʻoulu ai i ka ʻelemakule o ka hoʻonā uhi, pono e mālama ʻia ka mahana mālama o ka zinc flake coating solutions ma 10 DEG C. I ka manawa like ma lalo o ka lā, ua maʻalahi ka uhi ʻana i ka polymerize, hoʻololi a hiki i ka ʻōpala, no laila ʻoi aku ka maikaʻi o ka mālama ʻana i ka malu i ka mālamalama.ʻAʻole lōʻihi ka lōʻihi o ka mālama ʻana i ka pena paʻi zinc flake, no ka mea, ʻoi aku ka lōʻihi o ka hoʻomākaukau ʻana o ka uhi wai, ʻoi aku ka maʻalahi o ka piʻi ʻana o ka pH, ma muli o ka pau ʻana o ka ʻelemakule o ka wai, hōʻike nā hoʻokolohua ʻaʻole ʻaʻohe ʻōpala wai chromatedacromet ma hope o ka hoʻomākaukau ʻana i ka pono. ka manawa o ka mahana o 20 DEG C no 30 mau lā, pono ka mahana o 30 DEG C i ka lā 12, a i loko o kahi manawa o 40 deg.c no nā lā 5 wale nō.
Pono e noho nā haʻina hoʻoheheʻe Zinc flake i ke ʻano o ka haʻahaʻa haʻahaʻa, ʻo ke kiʻekiʻe ka wela e hana i ka ʻano o ka wā kahiko.
