ʻO Thermoplastic Acrylic Resins kahi papa o nā resins thermoplastic i hana ʻia e ka polymerizing acrylic acid, methacrylic acid a me nā mea i loaʻa e like me nā esters, nitriles, a me nā amides.Hiki ke hoʻopalupalu pinepine ʻia e ka wela a hoʻopaʻa ʻia e ka hoʻoluʻu.ʻO ka mea maʻamau, he hui polymer linear, he homopolymer a i ʻole copolymer, maikaʻi ke kino a me nā ʻano mechanical, maikaʻi loa i ka pale ʻana i ke aniau, ke kūpaʻa kemika, a me ke kūpaʻa wai, a he kiʻekiʻe ka nani a me ka paʻa kala.ʻO ka resin acrylic thermal i hoʻohana ʻia i ka ʻoihana hoʻopili maʻamau ka paona molekala o 75 000 a 120 000. Hoʻohana maʻamau ia me ka nitrocellulose, cellulose acetate butyrate a me ka perchlorethylene resin e hoʻomaikaʻi i nā waiwai kiʻiʻoniʻoni.
ʻO ka resin acrylic thermoplastic kahi ʻano o ka resin acrylic e hoʻoheheʻe ʻia, hiki ke hoʻoheheʻe ʻia a hoʻoheheʻe ʻia i loko o kahi solvent kūpono.ʻO ka uhi i hoʻomākaukau ʻia e ka mea hoʻoheheʻe ʻia e hoʻoheheʻe ʻia e ka solvent a hoʻohui ʻia ka macromolecule i kahi kiʻiʻoniʻoni, a ʻaʻohe hopena crosslinking i ka wā o ka hoʻokumu ʻana i ke kiʻiʻoniʻoni, ʻo ia ke ʻano non-reactive.ka uhi ʻana.I mea e hoʻokō ai i nā waiwai kino a me nā kemika maikaʻi, pono e hoʻonui ʻia ka paona molekala o ka resin, akā i mea e hōʻoia ai ʻaʻole haʻahaʻa loa ka ʻike paʻa, ʻaʻole hiki ke nui ke kaumaha o ka molekala, ma ke ʻano he ʻumi kaukani. mau manawa, ua kaulike nā waiwai kino a me nā kemika a me nā hana kūkulu.
