ʻO Polyester Acrylate 5202B - Ke Koho Kūpono no nā Uhi UV Hana Kiʻekiʻe
ʻO ka resin acrylate polyester 5202B, ua manaʻo ʻia he resin kumu i nā noi UV like ʻole, e like me ka uhi ʻana o UV, ka varnish pepa UV a me ka paʻi flexo UV. Loaʻa iā ia kekahi mau pono koʻikoʻi: haʻahaʻa ka viscosity, pae maikaʻi, maʻalahi koʻikoʻi, kiʻiʻoniʻoni wikiwiki, hoʻopili maikaʻi, pulu maikaʻi a me ka hiki ke polish maikaʻi loa.
ʻO ka Polyester Acrylate 5202B kahi resin UV hana kiʻekiʻe me ka hoʻohālikelike maikaʻi loa me ka hapa nui o nā monomers UV a me nā resins UV, e kūpono ana no nā ʻano uhi UV like ʻole, nā varnish pepa UV, ka paʻi pale UV, a me nā mea hou aku. Loaʻa iā ia ka viscosity haʻahaʻa, ka hiki ke kahe maikaʻi loa, ka maʻalahi kiʻekiʻe, ka hoʻokumu ʻana i kahi kiʻiʻoniʻoni wikiwiki, ka hoʻopili ikaika i nā ʻano substrates like ʻole, nā waiwai hoʻomaʻū maikaʻi loa no nā pigments a me nā mea hoʻopihapiha, a me ke one maikaʻi, e lilo ia i mea kūpono no nā uhi premium.
ʻO ka mea mua, ʻo ka mānoanoa haʻahaʻa o 5202B a me ke kahe maikaʻi loa e hōʻoia i ka pālahalaha like ʻana i ka wā o ka hoʻopili ʻana, e hōʻemi ana i nā hemahema a me ka hōʻoia ʻana i kahi ʻano uhi kīnā ʻole. ʻO kona maʻalahi kupaianaha e hiki ai i ka uhi ke kū i ka deformation me ka ʻole o ka haki ʻana, e hoʻonui ana i ka lōʻihi a me ke ola o ka huahana hope loa.
ʻO ka lua, hana koke ʻo 5202B i kahi ʻili paʻa, kahi e hoʻomaikaʻi ai i ka pono hana a hoʻokō i nā koi o nā laina hana wikiwiki. Eia kekahi, hōʻike ia i ka hoʻopili maikaʻi loa i nā ʻano substrates like ʻole, e hōʻoia ana i kahi pilina paʻa a lōʻihi e kūʻē i ka ʻili ʻana.
Eia kekahi, ʻo nā waiwai pulu maikaʻi loa o 5202B e ʻae iā ia e komo pono i loko o nā pigments a me nā mea hoʻopihapiha, e hoʻomaikaʻi ana i ka hana holoʻokoʻa o ka uhi ʻana a me ka hōʻoia ʻana i ka hoʻopuehu like ʻana. ʻO kona one maikaʻi loa e hoʻomaʻamaʻa ai i ka hana ʻana ma hope, e hāʻawi ana i ka maʻalahi i ka hoʻopau ʻana i ka ʻili.
ʻO Polyester Acrylate 5202B ke koho kūpono no ka hoʻomaikaʻi ʻana i ka maikaʻi o nā uhi UV, ka hoʻomaikaʻi ʻana i ka pono hana, a me ka hoʻokō ʻana i ka hana kiʻekiʻe. E koho iā 5202B e hōʻoia i kāu mau uhi UV e hoʻokō i nā kūlana kiʻekiʻe loa i ke kahe ʻana, ka hoʻopili ʻana, ka maʻalahi, a me ke one ʻana, e hāʻawi ana i nā hopena maikaʻi loa.
