7901B UV-resin no nā uhi ʻoihana

Polyurethane Acrylate 7901B: ʻO ka "Armour All-Purpose" no nā Uhi ʻOihana

Ma ke kahua hana kiʻekiʻe o ka ʻenekinia ʻili, kū ʻo Polyurethane Acrylate 7901B ma ke ʻano he pae hoʻohālikelike i nā UV vacuum metallization topcoats, nā ʻīnika UV, a me nā uhi ʻaʻahu pale haʻalulu. Me kona hoʻōla wikiwiki ʻana, ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻaʻahu RCA kūikawā, ke kūpaʻa ʻōpala, nā waiwai anti-yellowing, a me ka paʻakikī kaulike, hāʻawi ia i nā huahana me kahi pale kaua ʻike ʻole ʻia e hoʻohui pono i nā aesthetics me ka hana.

Hoʻōla wikiwiki loa: He hoʻololi i ka pono

Ma lalo o ka hōʻike ʻana o ka UV, ua hoʻopau ʻia ka crosslinking hohonu i loko o 3 kekona (ma ka nui o ka ikehu ≥100mJ/cm²), e kūpono ai no ka uhi ʻōwili wikiwiki a me nā laina hana hana automated. Hoʻomaikaʻi ia i ka pono hana ma 40% me ka hoʻemi ʻana i ka hoʻohana ʻana i ka ikehu unit ma 25%, ʻoi aku ka pōmaikaʻi o nā hale kelepona i hoʻoheheʻe ʻia me ka vacuum a me ka paʻi UV huahana 3C kiʻekiʻe.

Paʻakikī a me ke kūpaʻa ʻana i ka ʻaʻahu: Mākaukau no nā pilikia koʻikoʻi

Me ka paʻakikī o ka ʻili o 4H (paʻakikī penikala) a me ke kūpaʻa ʻana o ka ʻaʻahu RCA o ≥300 mau pōʻaiapuni (175g ukana), ʻoi aku ka maikaʻi o 7901B ma mua o nā uhi maʻamau. Kūpaʻa maʻalahi ia i nā ʻōpala koʻikoʻi a me ka ʻānai ʻana i ka lepo, e hōʻoiaʻiʻo ana i ka lōʻihi o ke kūpaʻa no nā pale kamepiula lawe lima a me nā mea hiki ke komo akamai.

Ke Kū'ē i ke Kāhili a me ka Anti-Yellowing: Kūpono ʻole i ka hala ʻana o ka manawa

Me ka hoʻohana ʻana i ka ʻenehana hybrid inorganic nano-scale, hoʻokō ia i ka paʻakikī Mohs >3, e hoʻonui ana i ke kūpaʻa ʻana i ka ʻōpala ma 50%. Me nā mea hoʻopaʻa UV synergistic, mālama ia i kahi ʻokoʻa kala ΔE

Paʻakikī Kaulike: Ikaika me ka Maʻalahi

Me ka modulus elastic i kāohi pono ʻia (500-800 MPa), hoʻohālikelike ia i ka paʻakikī 3H me ka elongation 5% i ka haki (ASTM D638), e kūpono ana no nā hinges pale pelu ʻia i hoʻoheheʻe ʻia i ka vacuum-metala a me nā uhi grille kaʻa e kūʻē i ka haʻalulu, e hōʻoiaʻiʻo ana i ke kūpaʻa ʻole o ka haki ma lalo o nā hopena alapine kiʻekiʻe.

Mai nā ʻāpana metala ʻālohilohi a hiki i nā uhi pale ʻaʻahu i nā wahi koʻikoʻi, wehewehe hou ʻo 7901B i ka hilinaʻi o ka uhi ʻoihana. Me kāna hana wikiwiki, paʻakikī, paʻa, paʻa, a maʻemaʻe hoʻi, hōʻoia ia e noho pū ana ka ʻenehana a me nā nani ma lalo o ka hoʻāʻo o ka manawa.
