Nano-titanium dioxide TIO2 ine yakakwira photocatalytic chiitiko uye ine yakakosha yekuona zvinhu.Nekugadzikana kwemakemikari zvivakwa uye akawanda masosi emidziyo, ikozvino ndiyo inonyanya kuvimbisa photocatalyst.
Zvinoenderana nerudzi rwekristaro, inogona kukamurwa kuita: T689 rutile nano titanium dioxide uye T681 anatase nano titanium dioxide.
Zvinoenderana nehunhu hwayo hwepamusoro, inogona kukamurwa kuita: hydrophilic nano titanium dioxide uye lipophilic nano titanium dioxide.
Nano titanium dioxide TIO2kunyanya ine mafomu maviri ekristaro: Anatase uye Rutile.Rutile titanium dioxide yakagadzikana uye yakaomesesa kupfuura anatase titanium dioxide, ine kuomarara kwepamusoro, density, dielectric constant uye refractive index, uye simba rayo rekuhwanda uye simba retinting zvakakwirira zvakare.Iyo anatase-type titanium dioxide ine ratidziro yepamusoro muchikamu chepfupi-saizi chechiedza chinooneka pane rutile-mhando titanium dioxide, ine bluish tint, uye ine yakaderera ultraviolet absorption kugona kupfuura rutile-rudzi, uye ine yakakwirira photocatalytic chiitiko kupfuura. Rutile-rudzi.Mune mamwe mamiriro ezvinhu, anatase titanium dioxide inogona kushandurwa kuita rutile titanium dioxide.
Environmental protection applications:
Kusanganisira kurapwa kwezvinosvibisa organic (hydrocarbons, halogenated hydrocarbons, carboxylic acids, surfactants, dhayi, nitrogen-ine organics, organic phosphorus mishonga yekuuraya zvipembenene, nezvimwewo), kurapwa kweinorganic zvinosvibisa (photocatalysis inogona kugadzirisa Cr6+, Hg2+, Pb2+, nezvimwewo). Kusvibiswa kweheavy metal ions) uye kucheneswa kwemukati kwezvakatipoteredza (kusvibiswa kwemukati ammonia, formaldehyde uye benzene nephotocatalytic green coatings).
Zvikumbiro muhutano hwehutano:
Nano-titanium dioxide inoparadza mabhakitiriya pasi pechiito che photocatalysis kuti iwane antibacterial effect, kuuraya mabhakitiriya uye mavhairasi, uye inogona kushandiswa pakuita sterilization uye disinfection yemvura yemumba;girazi, ceramics, etc. yakatakurwa neTIO2 photocatalysis inoshandiswa munzvimbo dzakasiyana-siyana dzehutsanana dzakadai sezvipatara, mahotera, dzimba, etc. Ideal material for antibacterial and deodorizing.Inogonawo kumisa mamwe masero anokonzera kenza.
Iyo bactericidal mhedzisiro yeTiO2 iri mune yayo quantum saizi maitiro.Kunyange zvazvo titanium dioxide (yakajairika TiO2) inewo photocatalytic effect, inogonawo kugadzira maerekitironi nemaburi maviri, asi nguva yaro yekusvika pamusoro pechinhu chiri pamusoro pe microseconds, uye zviri nyore kubatanidza zvakare.Zvakaoma kushandisa antibacterial effect, uye nano-dispersion degree yeTiO2, maerekitironi nemakomba anofara nechiedza anotama kubva mumuviri kuenda kumusoro, uye zvinongotora nanoseconds, picoseconds, kana kunyange femtoseconds.Kubatanidzwazve kwemaerekitironi akagadzirwa nemaburi ari Mukurongeka kwenanoseconds, inogona kukurumidza kutamira kumusoro, kurwisa hutachiona hwehutachiona, uye kutamba inowirirana inorwisa mabhakitiriya.
Anatase nano titanium dioxide ine yakakwirira pamusoro pekuita, yakasimba antibacterial kugona, uye chigadzirwa chiri nyore kuparadzira.Miedzo yakaratidza kuti nano-titanium dioxide ine simba rebhaktericidal rakasimba kurwisa Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Salmonella uye Aspergillus.Yakave yakatenderwa zvakadzika uye inoshandiswa zvakanyanya muzvigadzirwa zveantibacterial muminda yemachira, ceramics, rabha, uye mushonga.
Anti-fogging uye yekuzvichenesa coating:
Pasi pe ultraviolet irradiation, mvura inopinda zvachose mufirimu yetitanium dioxide.Naizvozvo, kupfekedza dhizaini ye nano-titanium dioxide pamagirazi ekugezera, girazi remotokari uye magirazi ekuona kumashure anogona kuita basa mukudzivirira fogging.Inogona zvakare kuona kuzvichenesa kwepamusoro pemarambi emumugwagwa, migwagwa mikuru, uye kuvaka mataira ekunze emadziro.
Photocatalytic basa
Mhedzisiro yechidzidzo ichi yakawana kuti pasi pekuita kwechiedza chezuva kana ultraviolet mwaranzi muchiedza, Ti02 inomutsa uye inogadzira mahara radicals ane yakakwira catalytic chiitiko, inogona kuburitsa yakasimba photooxidation uye kuderedza kugona, uye inogona kukonzeresa uye fotodegrade akasiyana formaldehyde akabatanidzwa pamusoro. zvezvinhu.Zvakadai seorganic matter uye imwe inorganic matter.Inogona kutamba basa rekuchenesa mhepo yemukati.
UV kudzivirira basa
Chero chero titanium dioxide ine imwe kugona kutora ultraviolet mwaranzi, kunyanya marefu-wave ultraviolet mwaranzi inokuvadza kumuviri wemunhu, UVA\UVB, ine simba rekunyudza.Yakanakisa kugadzikana kwemakemikari, kugadzikana kwekupisa, kwete-chepfu uye zvimwe zvinhu.Ultra-fine titanium dioxide ine simba rakasimba rekutora ultraviolet rays nekuda kwehukuru hwayo hudiki (pachena) uye basa rakakura.Mukuwedzera, ine ruvara rwakajeka toni, yakaderera abrasion, uye yakanaka nyore kupararira.Zvinotemerwa kuti titanium dioxide ndiyo inonyanya kushandiswa inorganic raw material muzvizoro.Zvinoenderana nemabasa ayo akasiyana muzvizoro, hunhu hwakasiyana hwetitanium dioxide hunogona kushandiswa.Kuchena uye kupenya kwetitanium dioxide inogona kushandiswa kugadzira zvizorwa zvine mavara akasiyana-siyana.Kana titanium dioxide inoshandiswa sechinhu chinowedzera chichena, T681 anatase titanium dioxide inonyanya kushandiswa, asi kana simba rekuhwanda uye chiedza chekudzivirira chinofungidzirwa , Zviri nani kushandisa T689 rutile titanium dioxide.
