Titanium dioxide (TiO2) is a versatile white pigment inoshandiswa mumaindasitiri akasiyana siyana, kusanganisira indasitiri yemapepa. Mumakore achangopfuura, kudiwa kwemhando yepamusoro titanium dioxide, kunyanya anatase titanium dioxide, kwave kukwira. China yave inotungamira mugadziri weanatase titanium dioxide, ichipa hunyanzvi hwekushandisa kuindasitiri yemapepa.
Anatase titanium dioxide kubva kuChina yakagamuchira kutariswa kwakapararira nekuda kwekuita kwayo kwakanaka uye mashandisirwo ehunyanzvi muindasitiri yemapepa. Anatase icrystalline fomu yeTiO2 ine yakakwira refractive index, yakanakisa kuparadzira mwenje zvivakwa uye inovandudza photocatalytic chiitiko. Izvi zvakasiyana zvivakwa zvinoita kuti zvive zvakanaka pakuvandudza kunaka uye kuita kwezvigadzirwa zvemapepa.
Imwe yemashandisirwo matsva eChinese anatasetitanium dioxidemuindasitiri yemapepa yakafanana nepigment yemhando yepamusoro. Kana yawedzerwa kumapepa ekuputira, anatase titanium dioxide inowedzera kupenya, kupenya uye kuchena kwepepa. Izvi zvinonatsiridza kusiyana kwekudhinda uye kuberekazve kwemavara, zvichiita kuti ive yakakodzera kudhinda uye kurongedza maapplication emhando yepamusoro.
Uye zvakare, anatase titanium dioxide kubva kuChina ine yakanakisa kuparadzira mwenje zvivakwa, izvo zvinobatsira kuvandudza optical maitiro epepa. Nekuparadzira zvakaenzana pigment mukati mekuvhara kwepepa, zvinobatsira kuwana nzvimbo yakatsetseka, inopenya inosimudzira kutaridzika kwebepa uye kudhinda.
Pamusoro pezvayo zvakanakira maziso, anatase titanium dioxide kubva kuChina inoshandawo seinoshanda UV blocker kana ichishandiswa mumapepa ekuputira. Iyi ficha inonyanya kukosha mukushandisa uko UV radiation inofanirwa kuchengetedzwa, senge zvinhu zvekurongedza uye zviratidzo zvekunze. Nekuwedzera anatase titanium dioxide, zvigadzirwa zvemapepa zvinogona kunge zvakavandudza kusimba uye kuramba kune UV-induced yellowing.
Uyezve, iyo photocatalytic chiitiko cheanatase titanium dioxide inovhura mikana mitsva yekuzvichenesa uye yekuchenesa mweya zvigadzirwa zvemapepa. Kana yaiswa pachiedza, titanium dioxide anatase inogona kukonzeresa kuita kwephotocatalytic iyo inopwanya organic compounds uye zvinosvibisa, zvichibatsira kugadzira yakachena, ine hutano nharaunda. Ichi chitsva chekushandisa chine mukana wakakura wemapepa ehunyanzvi anoshandiswa muhutsanana, hutano uye kuchengetedza kwezvakatipoteredza.
Kugadzirwa kweanatase titanium dioxide muChina kunopindirana zvakare neindasitiri yemapepa iri kuwedzera kukoshesa maitiro akasimba uye ane hushamwari. Nekufambira mberi mukugadzira maitiro uye kutonga kwemhando, vatengesi veChinese vanokwanisa kupa kuchena kwepamusoroanatase titanium dioxideiyo inosangana nemipimo yakasimba yezvakatipoteredza. Izvi zvinoita kuti vagadziri vemapepa vabatanidze mavara ane hushamwari kwezvakatipoteredza muzvigadzirwa zvavo, achizadzisa zvinodiwa nevatengi vanokoshesa zvakatipoteredza uye mabhizinesi.
Muchidimbu, kushandiswa kutsva kweChina anatase titanium dioxide kwakaunza kufambira mberi kwakakura kuindasitiri yekugadzira mapepa. Yayo yakasarudzika zvimiro, zvinosanganisira yakakwira refractive index, kugona kuparadzira mwenje, UV yekuvhara maitiro uye photocatalytic chiitiko, inoita kuti ive yakakosha yekuwedzera yekuvandudza mashandiro uye kusimba kwezvigadzirwa zvemapepa. Sezvo kudiwa kwemhando yepamusoro titanium dioxide kuri kuramba kuchikura, iko kushandiswa kweChina anatase zvechokwadi kuchasimudzira kufambira mberi muindasitiri yekugadzira mapepa uye nekupa mikana mitsva yekuvandudza mhando yechigadzirwa uye mutoro wezvakatipoteredza.
