Kau ʻia ma 2018-10-29Me ka hoʻomohala wikiwiki o ka ʻenehana hana hou, ʻoi aku ka nui o nā huahana kiʻekiʻe i hoʻohana ʻia i ka hana ʻana, ʻoi aku hoʻi i ka ʻoihana hana.Ua lawe mai ka ʻenehana hana i ka ʻoluʻolu i ko mākou ola, me ka uhi ʻana o Dacromet.
ʻO Dacromet coating, i ʻike ʻia ʻo zinc flake coating, hoʻohana nui ʻia i nā ʻoihana he nui.Ma waena o lākou,ʻo ka hui pūʻana o kaʻenehana Dacromet a me nā uhi e hoʻonui nui i ka hana anti-corrosion o nā huahana.No laila ʻike ʻoe i ke kumu e hiki ai iā ia ke pale i ka mea?
ʻO ka uhi Dacromet he matt kala-hina a loaʻa nā flakes maikaʻi loa o ka zinc, aluminika a me ka chromate.Ma hope o ka hoʻomaʻemaʻe ʻia ʻana o ka mea hana a pana ʻia i ka pana ʻana, ua uhi ʻia ka uhi me ka Dacromet.ʻO ka uhi ʻana ʻo Dacromet he ʻano wai hoʻoheheʻe wai, no ka hana ʻana i nā ʻāpana metala ma hope o ka uhi ʻana a i ʻole ka pulupulu ʻana i loko o ka wai uhi, i loko o ka umu ahi, ma kahi o 300 ℃ baking film, e hana ai i ka zinc, aluminika, chromium, inorganic coating.
I ka wā o ke kaʻina hana ho'ōla, hoʻololi ʻia ka wai a me nā mea ola (cellulose) i loko o ka uhi ʻoiai e hilinaʻi ana i ka oxidization o nā paʻakai chromium kumu kūʻai nui i loko o ka waiʻona makuahine o dacromet, a ua hoʻokumu ʻia nā pūhui paʻakai chromium o Fe, Zn a me Al ma hope o ka ka pane ʻana o ka pepa zinc hoʻokahi a me ka slurry pepa alumini me ka mana electrode maikaʻi ʻole me ka matrix hao.No ka mea, ua hana ʻia ka ʻāpana membrane ma hope o ka pane pololei ʻana me ka matrix, ua paʻa loa ka uhi. hiki ke ʻino i loko o ka matrix ponoʻī.
No ka ʻike hou aku e pili ana i ka dacromet, e kipa www.junhetec.com
