Pigment tsvuku yeCadmium imhando yepigment dzisina kugadzirwa dzakaumbwa semhinduro dzakasimba dzecadmium sulfide (CdS) necadmium selenide (CdSe). Selenium chaiyo (x) ndiyo inosarudza ruvara, ichichinja ruvara kubva kuorenji (low Se) kuenda kutsvuku yakadzama (high Se) nekuderedza bandgap kubva pa2.4 eV (pure CdS, yero) kuenda pa1.7 eV (pure CdSe, tsvuku).
Kuziva mavara muunyanzvi kwakaoma nekuda kwehuwandu hwe selenium ne cadmium, mamiriro emuviri, uye mavara akafanana emamwe mavara matsvuku. Huturu hwe selenium pigment uye zvirimo zve heavy metal zvinoita kuti pave nekuongororwa kwakasimba kwemitemo. Kuongorora kwakarurama kwemavara emavara kunotsigira kutevedzera mitemo, kuchengetedzeka, uye kuvimbika kwemazita.

Nheyo dzeXRF Spectroscopy dzeKuongorora Pigment
X-ray fluorescence (XRF) spectroscopy inokurudzira maatomu ari mu cadmium red pigment uchishandisa maX-ray ekutanga, ichiburitsa maerekitironi emukati. Atomu rinozorora nekubvisa maX-ray echipiri (fluorescent) ane simba rakasiyana nerezvinhu. Kune nzira dzekuongorora makemikari epigment, selenium's Kα neKβ peaks zvinoitika pa11.2 ne12.5 keV, zvichiteerana; cadmium inoonekwa pa23.1 keV. XRF inogonesa kuongorora composition yepigment yezvinhu zvakasimba pasina kukuvadza sampuro. XRF inopa ruzivo rwemhando yepamusoro uye huwandu, ichiona huwandu hwepigment yeselenium kusvika pazvikamu pamiriyoni mumamatrices akaoma. Kuonekwa kunoitika mumasekonzi, zvichigonesa kuyera mapeji epigment akaomarara mukuchengetedza art kana mamiriro ekusimbisa mhando.

XRF inoenderana nezvinodiwa zvisingaparadzi zvekushandiswa kwe cadmium red pigment, ichidzivirira micro-sampling inodiwa nenzira dzakadai seICP-OES kana AAS. Kana ichienzaniswa nenzira dzinoparadza dzekuona pigment, XRF inochengetedza mienzaniso yekare neyemazuva ano, ichitsigira nzira dzekuona pigment dzekuongorora kana kuongorora kuchengetedzeka kwepigment. XRF inoshanda nezvikamu zvakapendwa zvakasimba, pigments dzeupfu, uye zvinhu zvisina kukanganiswa, zvichigonesa kuongorora kwakanyatsojeka kwepigment uye kutevedzera chepfu ye selenium pigment mumabasa akasiyana-siyana uye maindasitiri.
Kuongororwa kweSelenium muCadmium Red Pigments neHunhu uye Huwandu
XRF inoita kuti selenium ionekwe zvakananga mu cadmium red pigment nekuona selenium Kα (11.2 keV) neKβ (12.5 keV) peaks dzakasiyana. Kuvapo kwe cadmium Kα (23.1 keV) ne selenium Kα lines zvinosimbisa kuti pigment iyi ine chimiro che cadmium sulfo-selenide.
Kuongororwa kweminwe neXRF spectrum kunosiyanisa pigment tsvuku yecadmium kubva kune yero ye cadmium sulfide yakachena kana mamwe mapigment matsvuku asina selenium. Pamusanganiswa kana shanduko, nzira dzakazara dzemaspectrum uye ongororo yemakemikari (semuenzaniso, ongororo yezvikamu zvikuru) zvinovandudza kusarura, zvichideredza kunaka kwenhema pakuona mavara muzvigadzirwa zvehunyanzvi kana zvemaindasitiri.

Mibvunzo Inowanzo bvunzwa
Chii chinonzi cadmium red pigment uye selenium inobatanidzwa sei mukuumbwa kwayo?
Pigment tsvuku yeCadmium imhando ye cadmium sulfoselenide, ine cadmiumsulfideuye 10–25% cadmium selenide. Maion eSelenium anogara munzvimbo dze lattice, achigadzira kusiyana kwemavara kubva kuorenji kusvika kutsvuku nekuchinja chiyero cheCdS:CdSe. Matrix ye crystalline inoita kuti ruvara ruve rwakasimba uye rugare. Selenium inowedzera kupenya kwemavara uye inowedzera kugara kwenguva refu kwepigment, yakakosha kune mavara emuimbi anogara aripo uye zvinhu zvemaindasitiri.
XRF spectroscopy inobatsira sei pakuziva ruvara rweganda?
XRF spectroscopy inoona cadmium neselenium zvakananga mumamatrices epigment akasimba kuti iongorore makemikari epigment asingaparadze. Zvinhu zvakakosha, zvinosanganisira cadmium Kα (23.2 keV) neselenium Kα (11.2 keV), zvinoita kuti pave nekuzivikanwa nekukurumidza kwemavara epigment. Nzira iyi inosiyanisa mapigment eselenium nemazvo kubva kune mamwe marudzi, nemiganhu yekuona iri pasi pe50 ppm zvichienderana nechimiro chematrix uye geometry yemuenzaniso.
Sei zvichikosha kuona huwandu hwe selenium mu pigments?
Kunyora huwandu hweseleniamu kunodiwa kuti pave nekuchengetedzwa kwepigment, kugadzirwa kwacho kuenderane, uye kutevedzera mitemo yepasi rose pamusoro pekusvibiswa kwezvakatipoteredza nevashandi. Selenium yakawandisa inowedzera njodzi yekukuvadzwa kwepigment uye inokanganisa kudzokororwa kwemumvuri. Magadzirirwo epigment eselenium akadzorwa anovimbisa kutevedzera mitemo uye kushanda zvakanaka kwepigment muhunyanzvi,machira ekuputira, uye mapurasitiki.
