Ka hoʻohana ʻana i ka Titanium Dioxide i nā huahana palaki
ʻOiai ʻo ka lua o ka mea hoʻohana nui loa o ka titanium dioxide, ʻo ka ʻoihana plastics ka wikiwiki e ulu nei i nā makahiki i hala iho nei, me ka awelika o ka ulu ʻana o ka makahiki he 6%.Ma waena o nā māka titanium dioxide ma mua o 500 i ka honua, ʻoi aku ma mua o 50 mau māka i hoʻolaʻa ʻia i nā plastics.ʻO ka hoʻohana ʻana i ka titanium dioxide i nā huahana plastik, ma kahi o ka hoʻohana ʻana i kona mana huna kiʻekiʻe, ka mana achromatic kiʻekiʻe a me nā waiwai puaʻa ʻē aʻe, hiki iā ia ke hoʻomaikaʻi i ka pale wela, ka pale māmā a me ka pale ʻana i ka wā o nā huahana plastik, i pale ʻia nā huahana plastik mai kukui UV.Invasion, hoʻomaikaʻi i nā waiwai mechanical a me nā uila o nā huahana plastik.
No ka mea ʻoi aku ka mānoanoa o nā huahana plastik ma mua o nā pena a me nā inika, ʻaʻole ia e koi i kahi kiʻekiʻe o ka nui o nā pua puaʻa, a me ka mana huna kiʻekiʻe a me ka mana o ka tinting ikaika, a ʻo ka dosage maʻamau he 3% a 5% wale nō.Hoʻohana ʻia ʻo ia i nā mea ʻeleʻele thermosetting a me nā thermoplastic plastics, e like me polyolefins (nui loa ka polyethylene haʻahaʻa haʻahaʻa), polystyrene, ABS, polyvinyl chloride, a me nā mea ʻē aʻe.Hoʻohui ʻia ka ʻāpana wai o ka plasticizer, a hoʻohana ʻia kekahi ma hope o ka hoʻoili ʻana i ka titanium dioxide i loko o kahi masterbatch.
Ka noiʻi noiʻi kikoʻī o ka titanium dioxide i ka ʻoihana plastik a me ka ʻoihana masterbatch kala
ʻO ka hapa nui o ka titanium dioxide no nā plastics ka nui o nā ʻāpana.ʻO ka maʻamau, ʻo ka nui o ka titanium dioxide no ka uhi ʻana he 0.2 ~ 0.4μm, ʻoiai ʻo ka nui o ka titanium dioxide no nā plastics he 0.15 ~ 0.3μm, i hiki ke loaʻa i kahi polū.ʻO ka hapa nui o nā resins me ka pae melemele a i ʻole nā resins i maʻalahi i ka melemele he hopena masking.
ʻO ka Titanium dioxide no nā plastic plastic maʻamau, ʻaʻole ia e hoʻomaʻamaʻa i ka ʻili, no ka mea, ua uhi ʻia ka titanium dioxide me nā mea inorganic e like me ka alumina hydrated maʻamau, inā he 60% ka haʻahaʻa haʻahaʻa, ʻo ka adsorption equilibrium wai ma kahi o 1%, ke ʻoki ʻia ka plastic i ka wela kiʻekiʻe. .I ka wā o ka hana ʻana, ʻo ka hoʻoheheʻe ʻana o ka wai e ʻike ʻia nā pores ma luna o ka ʻili plastik maʻemaʻe.ʻO kēia ʻano o ka titanium dioxide me ka ʻole o ka uhi ʻole ʻole ʻia e hana maʻamau i ka mālama ʻana i ka honua (polyol, silane a i ʻole siloxane), no ka mea, hoʻohana ʻia ka titanium dioxide no nā plastics.ʻOkoʻa mai ka titanium dioxide no ka uhi ʻana, ua hana ʻia ka mea mua a hui pū ʻia me ka resin polarity haʻahaʻa e ka ikaika shearing, a hiki ke hoʻopuehu maikaʻi ʻia ka titanium dioxide ma hope o ka mālama ʻana i ka honua ma lalo o ka ikaika shearing mechanical kūpono.
Me ka hoʻonui mau ʻana o ka hoʻohana ʻana o nā huahana plastik, nui nā huahana plastik waho, e like me nā puka plastik a me nā puka makani, nā mea kūkulu hale a me nā huahana plastik waho ʻē aʻe, loaʻa nā koi kiʻekiʻe no ka pale ʻana i ka wā.Ma kahi o ka hoʻohana ʻana i ka rutile titanium dioxide, pono nō hoʻi ka mālama ʻana i ka ʻili.ʻAʻole hoʻohui ʻia kēia ʻano lapaʻau i ka zinc, hoʻohui wale ʻia ke silika, aluminika, zirconium, etc.He hopena hydrophilic a dehumidifying ʻo Silicon, hiki ke pale i ka hoʻokumu ʻana o nā pores ma muli o ka evaporation o ka wai i ka wā e hoʻokuʻu ʻia ai ka plastic i ke kiʻekiʻe wela, akā ʻaʻole nui ka nui o kēia mau mea lapaʻau.
