Titanium Dioxide yeMugwagwa Kumaka

Titanium dioxide (TiO2) chicherwa chinongoitika chinowanzo shandiswa mumaindasitiri akasiyana siyana. Kana zvasvika kune mamaki emumugwagwa, titanium dioxide chinhu chakakosha chemukati nekuda kweiyo yakasarudzika yekuona zvinhu. Iyo yakakwira refractive index inovimbisa kupenya kwakanakisa uye kuoneka, zvichiita kuti mamaki emigwagwa aonekwe zvakanyanya kunyangwe mumamiriro echiedza chakaderera. Izvi zvinonyanya kukosha kana uchityaira usiku kana mumamiriro ekunze asina kunaka apo kuonekwa kunonyanya kuderedzwa.

Pamusoro pekuonekwa kwepamusoro, titanium dioxide inopa kusimba kwenguva refu. Kuratidzwa kwemavara emumugwagwa kune yakaoma mamiriro ezvakatipoteredza senge traffic yakawandisa, tembiricha yakanyanyisa uye UV mwaranzi inogona kukonzera kuparara nekukurumidza. Nekudaro, mamaki emumigwagwa ane TiO2 anoshingirira zvakanyanya kudzima, kudonha uye kupfeka kunokonzerwa nezvinhu izvi, kuve nechokwadi chehupenyu hwesevhisi uye kuderera kwemitengo yekugadziridza.

Imwe yemabhenefiti makuru ekushandisa titanium dioxide yekumaka mugwagwa ndeye hushamwari hwezvakatipoteredza. Kusiyana nemamwe ma pigment, titanium dioxide haina chepfu, haina ngozi uye haina njodzi yehutano kune zvakatipoteredza kana vashandi. Pamusoro pezvo, titanium dioxide-yakavakirwa migwagwa inocherekedza haiburitse makemikari anokuvadza mumhepo, zvichiita kuti ive sarudzo yakagadzikana yezvifambiso zvezvifambiso.

Pamusoro pezvo, titanium dioxide inokwanisa kuratidza nekuparadzira chiedza, ichideredza kudiwa kwekuwedzera mwenje mumugwagwa. Izvi hazvisi izvo chete zvinoponesa simba uye zvinosimudzira kusimudzira, zvakare zvinovandudza kuoneka kwevatyairi nevanofamba netsoka.

Panyaya yekushandiswa, titanium dioxide inogona kuiswa nyore nyore mumigwagwa yakasiyana-siyana yekumaka zvinhu sependi, thermoplastics uye epoxies. Inogona kushandiswa kune akasiyana-siyana emakaka emumugwagwa, anosanganisira epakati, edgelines, crosswalks uye zviratidzo, kuve nechokwadi chekuenderana uye chakabatana chitarisiko pane network yemugwagwa.

Mukugadzira pendi yekugadzira dhizaini, kunze kwekusarudza yakakodzera titanium dioxide giredhi, imwe nyaya yakakosha ndeyekuti ungaziva sei kunyatso shandiswa kwetitanium dioxide. Izvi zvinoenderana nekudiwa kwekuputira opacity asi zvakare inotengeswa nezvimwe zvinhu zvakaita sePVC, kunyorova uye kupararira, ukobvu hwefirimu, solids content uye kuvapo kwemamwe mavara emavara. Kune tembiricha yekamuri yekurapa yakanyungudika-yakavakirwa machena machira, iyo titanium dioxide yemukati inogona kusarudzwa kubva pa350kg/1000L yemhando yepamusoro yekupfeka kusvika 240kg/1000L yekupfeka ehupfumi apo PVC iri 17.5% kana chiyero che0.75: 1. Iyo yakasimba dosage ndeye 70% ~ 50%; nokuda kwekushongedza latex pendi, apo PVC CPVC, huwandu hwetitanium dioxide hunogona kuwedzera kuderedzwa nekuwedzera kwesimba rakaoma rokuvanda. Mune mamwe ehupfumi ekuputira maumbirwo, huwandu hwetitanium dioxide hunogona kudzikiswa kusvika pa20kg/1000L. Muchivakwa chepamusoro-chivakwa chekunze kwemadziro ekunze, zviri mukati metitanium dioxide zvinogona kuderedzwa kusvika kune imwe chikamu, uye kunamatira kweiyo firimu yekuputira kunogonawo kuwedzerwa.
