Titanium dioxide (TiO2) ivara chena rinoshandiswa zvakasiyana-siyana rinoshandiswa mumaindasitiri akasiyana siyana, kusanganisira pendi, machira, mapurasitiki uye zvekuzora. Hunhu hwayo hwakasiyana hunoita kuti ive chinhu chakakosha pakuwana ruvara rwaunoda, opacity uye kupenya kwechigadzirwa chako. Nekudaro, kuti uwane zvizere mabhenefiti etitanium dioxide, zvakakosha kuve nechokwadi chekupararira kunoshanda panguva yekushandisa. Kupararira kwakakodzera kweTiO2 poda kanatitanium dioxide kupararirayakakosha pakuwedzera kuita kwayo uye kuwana mhedzisiro inodiwa. Muchinyorwa chino tichatarisa mamwe matipi ekuparadzira zvinobudirira titanium dioxide kuti iwedzere kushandiswa kwayo mumaindasitiri akasiyana.
1. Nzwisisa kupararira kwetitanium dioxide
Usati wanyura mune matipi ekupararira kunobudirira, zvakakosha kuti unzwisise pfungwa yekupararira uye kukosha kwayo mukushandisa titanium dioxide. Dispersion inoreva kugovera kwakafanana kweTiO2 zvimedu mupakati senge mvura kana yakasimba matrix. Kupararira kwakakodzera kunovimbisa kugovera kwakafanana kwetitanium dioxide zvidimbu, kudzivirira kuungana uye kukurudzira kuita kwakaringana kwechigadzirwa chekupedzisira.
2. Sarudza nzira yakakodzera yetitanium dioxide dispersion
Kune nzira dzakawanda dzekuparadziratitanium dioxide, kusanganisira kupararira kwemvura, kupararira kwakaoma, kurapwa kwepamusoro, etc. Kusarudzwa kwenzira yekuparadzira kunoenderana nekushandiswa kwakananga uye maitiro eTiO2 dispersion medium. Semuyenzaniso, muindasitiri yependi uye yekupotera, kupararira kwemvura kunowanzoitwa uchishandisa madhiri-kumhanya kana mill midhiya kuti uwane yunifomu yekugovera.
3. Shandisa zvigadzirwa zvemhando yepamusoro titanium dioxide
Hunhu hwetitanium dioxide hupfu kana kupararira hunoita basa rinokosha pakuwana kupararira kunobudirira. Yepamusoro-mhando titanium dioxide zvigadzirwa zvinofanirwa kubva kune vane mukurumbira vatengesi kuti ive nechokwadi chakafanana saizi, chimiro uye kupera kwepasi. Zvigadzirwa zvemhando yepamusoro titanium dioxide zvinopararira zviri nyore uye zvinopa kukwidziridzwa kwekuita mumhando dzakasiyana dzekushandisa.
4. Optimize formula uye maitiro parameters
Pamusoro pekusarudza nzira chaiyo yekuparadzira uye yepamusoro-mhando yeTiO2 zvigadzirwa, optimization yekugadzira uye maitiro maparamita kwakakoshawo kuti uwane kupararira kunoshanda. Zvinhu zvakadai setitanium dioxide concentration, dispersant selection, uye mamiriro ekugadzirisa (semuenzaniso, tembiricha, shear rate) zvinogona kukanganisa zvakanyanya kupararira. Nekunyatsogadzirisa ma parameter aya, vagadziri vanogona kuwana kupararira kuri nani uye kuwedzera kushanda kwetitanium dioxide muzvigadzirwa zvavo.
5. Shandisa advanced dispersion equipment
Kuisa mari mumidziyo yekuparadzira yepamberi inogona kuvandudza zvakanyanya maitiro ekuparadzira uye kuwedzera kushandiswa kwetitanium dioxide. High-speed dispersers, bead mills, uye ultrasonic homogenizers mienzaniso yezvigadzirwa zvepamusoro zvinogona kuparadzira zvimedu zveTiO2, nokudaro zvichivandudza kupa kwemavara, opacity, uye kusimba kwechigadzirwa chekupedzisira.
6. Kuita kutonga kwehutano uye kuedza
Kuti ive nechokwadi chekupararira uye kunoshanda kupararira kwetitanium dioxide, kunyatso kudzora kwemhando uye kuyedzwa kunofanirwa kuitwa mukati mekugadzira maitiro. Izvi zvinosanganisira kutarisa kugoverwa kwesaizi, kuongorora kukura kwemavara, uye kuongorora rheological zvimiro zvekupararira. Nekushandisa matanho akasimba ekudzora emhando, vagadziri vanogona kuona nekugadzirisa chero nyaya dzine chekuita nekupararira, nekudaro vachivandudza kuita kwechigadzirwa.
Muchidimbu, kuwedzeratitanium dioxide inoshandiswazvinoda kunyatsotarisisa kupararira. Nekunzwisisa misimboti yekupararira, kusarudza nzira chaiyo yekuparadzira, kushandisa emhando yepamusoro titanium dioxide zvigadzirwa, optimizing mafomula uye magadzirirwo paramita, uchishandisa advanced dispersion midziyo, uye kuitisa yakasimba yemhando kutonga, vagadziri vanogona kuzadzisa kupararira kunoshanda uye kusunungura iyo yakazara mukana wetitanium. diokisi. Iyo sulfur dioxide inogona kuwanikwa muzvigadzirwa zvavo. Kupararira kunobudirira hakungonatsiridza kuita kwetitanium dioxide, asi kunobatsirawo kuvandudza huwandu hwese uye kushanda kwechigadzirwa chekupedzisira mumaindasitiri.
