Ua kapa ʻia ka pauka melamine melamine formaldehyde molding plastics.Hoʻokumu ʻia ia ma ka melamine formaldehyde resin me ka alfa cellulose ma ke ʻano he hoʻopiha, hoʻohui i ka puaʻa a me nā mea hoʻohui ʻē aʻe.Loaʻa iā ia nā hiʻohiʻona o ke kūpaʻa wai, ke kūpaʻa wela kiʻekiʻe, ʻaʻohe mea ʻawaʻawa, kala ʻulaʻula, hoʻoheheʻe kūpono.Hoʻohana nui ʻia ia i nā ʻano kīʻaha melamine a pau, nā ipu, nā ʻāpana uila a me nā huahana ʻē aʻe.Hiki ke hoʻoheheʻe ʻia nā ʻōpala Urea-formaldehyde a me nā melamine-formaldehyde e ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana.Hoʻoheheʻe ʻia nā huahana pauka a kaomi ʻia i ke ʻano.Hana ʻia ka papa ʻaina melamine me ka pauka melamine ma o ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe.
ʻO ka melamine resin e pili ana i ka melamine formaldehyde resin i ʻike ʻia he melamine formaldehyde molding plastics, i hoʻopau ʻia ʻo "MF".ʻO ka melamine formaldehyde resin, i kapa ʻia ʻo melamine resin, i hana ʻia me ka pauka melamine.He resin i hana ʻia e ka condensation polymerization o ka melamine pauka a me ka formaldehyde ma lalo o nā kūlana micro-alkali.Loaʻa i ka melamine resin nā hiʻohiʻona o ka pale wai, ke kūpaʻa alkali, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa dielectric a me ka hoʻoheheʻe kūpono a me nā mea ʻē aʻe. E like me ka wela deformation wela a hiki i 180 degere, hiki ke hoʻohana ʻia i ka wela kiʻekiʻe ma luna o 100 degere no ka manawa lōʻihi.ʻO ka hoʻopaʻa ʻana o ka lapalapa ahi e like me ka pae UL94V-0.He māmā ke kala maoli o Resin, no laila hiki ke waiho wale ʻia.He waihoʻoluʻu, ʻaʻohe ona, ʻono ʻole a ʻona ʻole.
