Coloring pigments ndiyo inonyanya kukosha mbishi yekugadzira tekinoroji, uye zvimiro zvavo zvinofanirwa kunzwisiswa zvizere uye kushandiswa zvakachinjika, kuitira kuti emhando yepamusoro, yakaderera uye inokwikwidza mavara inogona kuumbwa.
Inowanzo shandiswa pigment yepurasitiki ruvara rwekuenzanisa inosanganisira inorganic pigments, organic pigments, solvent dyes, metal pigments, pearlescent pigments, magic pearlescent pigments, fluorescent pigments uye whitening pigments.Muzvinyorwa zviri pamusoro apa, tinofanira kujekesa kuti pane musiyano pakati pe pigment nedhayi: pigments hainyunguswi mumvura kana mukati inoshandiswa, uye iboka rezvinhu zvine ruvara zvinoisa ruvara rwemavara mumamiriro epamusoro. zvidimbu zvakaparadzirwa.Pigments uye organic pigments.Dhayi dzinonyungudika mumvura uye organic solvents, uye inogona kusanganiswa neiyo dhayi zvinhu neimwe makemikari bond.Mabhenefiti edhayi akaderera density, yakakwira tinting simba uye kujeka kwakanaka, asi iwo general molecular chimiro idiki, uye kutama kuri nyore kuitika panguva yekupenda.
Inorganic Pigments: Inorganic pigments inowanzoiswa nenzira yekugadzira, basa, chimiro chemakemikari, uye ruvara.Zvinoenderana neyakagadzirwa nzira, yakakamurwa kuita mapoka maviri: echisikigo pigments (senge cinnabar, verdigris uye mamwe mamineral pigments) uye ekugadzira pigments (senge titanium dioxide, iron tsvuku, nezvimwewo).Maererano nebasa, rakakamurwa kuva coloring pigments, anti-ngura pigments, anokosha pigments (senge tembiricha pigments, pearlescent pigments, fluorescent pigments), etc. Acids, etc. Maererano kemikari chimiro, inokamurwa kuita iron. series, chromium series, lead series, zinc series, metal series, phosphate series, molybdate series, etc. Maererano nemuvara, inogona kugoverwa muzvikamu zvinotevera: white series pigments: titanium dioxide, zinc barium white, zinc oxide, etc.;black series pigments: carbon black, iron oxide black, nezvimwewo;yellow series pigments: chrome yero, iron oxide yero, cadmium Yero, titanium yero, nezvimwe;
Organic Pigments: Organic pigments yakakamurwa kuita mapoka maviri: natural and synthetic.Mazuva ano, synthetic organic pigments inowanzoshandiswa.Synthetic organic pigments inogona kupatsanurwa muzvikamu zvakati senge monoazo, disazo, nyanza, phthalocyanine uye fused ring pigments.Zvakanakira organic pigments isimba rakanyanya tinting, ruvara rwakajeka, yakazara color spectrum uye yakaderera toxicity.Izvo zvisingabatsiri ndezvokuti chiedza chekudzivirira, kupisa kwekushisa, kupikisa kwemamiriro ekunze, kupikisa kwekugadzirisa uye kuvanza simba rechigadzirwa hazvina kunaka seye inorganic pigments.
Solvent Dyes: Madhayi ekunyungudutsa ndiwo makomisheni anotora, anotumira (dhayi ese aripachena) mamwe mafungu echiedza uye haaratidzi mamwe.Zvinoenderana nekunyungudika kwayo muzvinonyungudutsa zvakasiyana, inonyanya kukamurwa kuita zvikamu zviviri: imwe idhayi-inonyungudika nedoro, uye imwe idhayi-anonyungudika nemafuta.Madhayi anonyungudutsa anoratidzirwa nehukuru hwekupenya simba, mavara akajeka uye kupenya kwakasimba.Iwo anonyanya kushandiswa kupendesa styrene uye polyester polyether epurasitiki zvigadzirwa, uye kazhinji haashandiswe kupaka ruvara rwepololefin resins.Marudzi makuru ndeaya anotevera.Anthraaldehyde type solvent dyes: seC.1.Solvent Yellow 52#, 147#, Solvent Red 111#, Disperse Red 60#, Solvent Violet 36#, Solvent Blue 45#, 97#;Heterocyclic solvent dyes: zvakadai seC .1.Solvent Orange 60#, Solvent Red 135#, Solvent Yellow 160:1, zvichingodaro.
