Titanium Dioxide
Nā Hoʻonui PVC Hoʻomau me ka Titanium Dioxide
He pigment keʻokeʻo inorganic maʻalahi a hoʻohana nui ʻia ka Titanium Dioxide i ʻike ʻia no kona opacity kūikawā, keʻokeʻo, a me ka ʻōlinolino. He mea ʻawaʻawa ʻole ia, e palekana ai no nā ʻano hana like ʻole. ʻO kona hiki ke hoʻomālamalama a hoʻopuehu i ka mālamalama e makemake nui ʻia ai i nā ʻoihana e pono ai ka pigment keʻokeʻo kiʻekiʻe.
ʻO kekahi o nā hoʻohana koʻikoʻi o Titanium Dioxide ma ka ʻoihana pena waho. Hoʻohana pinepine ʻia ia ma ke ʻano he mea nui i nā pena waho e hāʻawi i ka uhi maikaʻi loa a me ke kūpaʻa UV. I ka ʻoihana plastics, hoʻohana ʻia ʻo Titanium Dioxide ma ke ʻano he mea hoʻokeʻokeʻo a me ka opacifying, e hoʻohui ana i nā huahana plastic like ʻole e like me nā paipu PVC, nā kiʻiʻoniʻoni, a me nā ipu, e hāʻawi ana iā lākou i kahi ʻano mālamalama a opaque. Eia kekahi, ʻo kona mau waiwai pale UV e kūpono ia no nā noi i hōʻike ʻia i ka lā, e hōʻoiaʻiʻo ana ʻaʻole e palaho a hoʻololi paha nā plastics i ka hala ʻana o ka manawa.
Loaʻa pū ka pōmaikaʻi i ka ʻoihana pepa mai ka Titanium Dioxide, kahi e hoʻohana ʻia ai e hana i ka pepa keʻokeʻo ʻālohilohi a kiʻekiʻe. Eia kekahi, i ka ʻoihana ʻīnika paʻi, ʻo kona hiki ke hoʻopuehu mālamalama e hoʻonui i ka ʻālohilohi a me ka ikaika o ke kala o nā mea i paʻi ʻia, e hoʻolilo ana iā lākou i mea nani a olaola.
| Mea | TP-50A | TP-50R |
| Inoa | ʻAnatase Titanium Dioxide | ʻO ka Titanium Dioxide Rutile |
| Paʻa | 5.5-6.0 | 6.0-6.5 |
| ʻIke TiO2 | ≥97% | ≥92% |
| Mana Hoʻemi Tint | ≥100% | ≥95% |
| Lelelele ma 105 ℃ | ≤0.5% | ≤0.5% |
| Ka omo ʻana o ka ʻaila | ≤30 | ≤20 |
Eia kekahi, loaʻa i kēia pigment inorganic nā noi i ka hana ʻana o nā fiber kemika, ka hana ʻana i ka rubber, a me nā mea hoʻonani. I loko o nā fiber kemika, hāʻawi ia i ke keʻokeʻo a me ka ʻālohilohi i nā lole synthetic, e hoʻonui ana i ko lākou ʻano hiʻohiʻona. I loko o nā huahana rubber, hāʻawi ʻo Titanium Dioxide i ka pale ʻana mai ka radiation UV, e hoʻolōʻihi ana i ke ola o nā mea rubber i hōʻike ʻia i ka lā. I loko o nā mea hoʻonani, hoʻohana ʻia ia i nā huahana like ʻole e like me ka sunscreen a me ke kahua e hāʻawi i ka pale UV a hoʻokō i nā leo kala i makemake ʻia.
Ma waho aʻe o kēia mau noi, he kuleana ko Titanium Dioxide i ka hana ʻana i ke aniani refractory, glazes, enamel, a me nā ipu hoʻokolohua kūpaʻa wela kiʻekiʻe. ʻO kona hiki ke kū i nā mahana koʻikoʻi e kūpono ai no ka hoʻohana ʻana i nā wahi wela kiʻekiʻe a me nā noi ʻoihana kūikawā.
I ka hopena, ʻo ka opacity kūikawā o Titanium Dioxide, ke keʻokeʻo, a me ka ʻālohilohi e lilo ia i mea pono ʻole i nā ʻoihana like ʻole. Mai nā pena waho a me nā plastics a hiki i ka pepa, nā ʻīnika paʻi, nā olonā kemika, ka laholio, nā mea hoʻonani, a me nā mea kūikawā e like me ke aniani refractory a me nā ipu wela kiʻekiʻe, ʻo kona mau waiwai versatile e kōkua i ka hana ʻana i nā huahana kiʻekiʻe a nani hoʻi i ka nānā aku.
Ka laulā o ka noi
