ʻO ka ili o ka paipu kila galvanized he maʻemaʻe loa, i ka hoʻohana lōʻihi ʻana o ka substrate e hana pū ʻia ka rust, i mea e hōʻoia ai i ka hoʻohana maʻamau o ka paipu galvanized, hiki i ke ala o ka pena ke pale aku i ka metala.Eia naʻe, no ka galvanized kila paipu, ka hapa nui o ka pena no ka galvanized ili adhesion mea ole maikai, pena kiʻiʻoniʻoni a me ka laumania ili adhesion mea ilihune, prone i ka uhi ana i ka pilikia, no laila, galvanized kila paipu me ka mea pena i oi?
ʻO ED1000 Epoxy Primer kahi uhi kūikawā no ka ʻili o ka substrate galvanized me ka adhesion maikaʻi loa a me ka pale maikaʻi no nā paipu galvanized.ʻO nā hiʻohiʻona nui o ka primer:
1. He kūpono no ka substrate galvanized, ke kila kila, ke alumini alumini, ka pā alumini a me nā metala maʻemaʻe ʻē aʻe, paʻa ikaika, paʻa paʻa kiʻiʻoniʻoni;
2, maʻalahi ka mālama ʻana o ka substrate, ʻaʻohe sandblasting, ʻaʻohe wili, hiki ke kūkulu ʻia ka hoʻohana ʻana i ka solvent e wehe i ka aila, mālama i nā koina kanaka a me nā kumu waiwai;
3, ikaika ka paʻakai paʻakai paʻakai, a hiki i 1000 mau hola, paʻa ka uhi, me ka anticorrosive maikaʻi loa a me ka pale ʻana;
4. ʻAʻole i loko o ka pena nā metala koʻikoʻi, ke alakaʻi a me ka chromium, e like me ka EU solvent emission standards, a ua kūpono no ka hoʻokuʻu ʻia ʻana o ka uhi hana;
5, hiki ke hoʻohālikelike ʻia me nā ʻano pena hoʻopau, e like me ka pena fluorocarbon, ka pena polyurethane, ka pena epoxy, ka pena acrylic, etc.
Pono e hoʻoneʻe ʻia ka paipu kila Galvanized ma mua o ka pena ʻana i ka ʻaila ʻili, ʻo ka hoʻohana ʻana i ka solvent e holoi i ka ʻili o ka substrate hiki ke wehe maikaʻi i ka ʻaila aila, e pale aku i ka pili ʻana.E hoʻopili i ka ED1000 epoxy primer ma ka pulupulu, e hui i ka primer a me ka lāʻau lapaʻau i ka ratio o 9: 1, e hoʻohui i ka epoxy thinner, e hoʻoulu like, a me ka lole i ka mānoanoa film i kuhikuhi ʻia.ʻO 70μm ka mānoanoa kiʻi i ʻōlelo ʻia.
Loaʻa i ka ED1000 epoxy primer ka hoʻopili ikaika a me ka pale ʻana i ka corrosion maikaʻi loa, akā maikaʻi ʻole ke kū ʻana o ka wā, ʻoi aku hoʻi no ka hoʻohana ʻana i waho, pono e hoʻohālikelike ʻia me ka topcoat kū i ka wā.Hoʻohana maʻamau, e like me ka pena fluorocarbons, ka ʻaʻahu polyurethane acrylic a me ka ʻaʻahu kiʻekiʻe.Ma hope o ka maloʻo ʻana o ka primer, e hoʻopili i ka topcoat a kāpīpī i ka mānoanoa film i kuhikuhi ʻia.ʻO ka mānoanoa kiʻi ʻoniʻoni i ʻōlelo ʻia he 50-60μm.
ʻO ka paipu Galvanized me ka primer a me ka hoʻopau ʻana i ka uhi ʻana, ʻoi aku ka maikaʻi o ka hoʻopili ʻana i ke kiʻiʻoniʻoni, ka pale ʻana i ka corrosion, ka hoʻonaninani a me ke kūʻē ʻana i ka wā, i ka hapa nui o ke kaiapuni hiki ke palekana maikaʻi loa.
