makemikari maitiro

Ultraviolet absorber imhando yemwenje stabilizer, inogona kutora chiedza chezuva uye fluorescent mwenje sosi muultraviolet chikamu, asi pachayo haichinji.
Nekuti mwaranzi yezuva ine huwandu hukuru hwechiedza cheultraviolet chinokuvadza kuzvinhu zvine mavara, kureba kwaro kunosvika 290-460 nanometers, aya anokuvadza ultraviolet mwenje kuburikidza nekemikari Redox reaction, mamorekuru emavara anopedzisira aora uye kupera.
Kune zvese zvemuviri uye zvemakemikari nzira dzekudzivirira kukuvara kwemavara kubva kune inokuvadza UV mwenje.
Heino sumo pfupi yemakemikari nzira, ndiko kuti, kushandiswa kweUV absorbers kuchengetedza chinhu chinoshanda kudzivirira, kana kuderedza kuparadzwa kwayo kwemavara.
Uv absorbers inofanira kuva nemamiriro anotevera
(1) inogona kunyatsotora ultraviolet chiedza (kunyanya iyo wavelength ye290-400nm);(2) Kugadzikana kwakanaka kwekushisa, kunyange mukugadzirisa hakuzoshanduki nekuda kwekupisa, kupisa kwekushisa kuduku;Kugadzikana kwakanaka kwekemikari, hapana kukanganisa kwakashata nezvikamu zvezvinhu muchigadzirwa;(4) Miscibility yakanaka, inogona kuparadzirwa zvakaenzana muzvinhu, pasina chando, hapana exudation;(5) Kugadzikana kwepikicha yezvinyoro pachayo yakanaka, haina kuora, haishanduki ruvara;⑥ isina ruvara, isina chepfu, isinganhuhwi;⑦ kuramba kunyudza washing;⑧ Yakachipa uye iri nyore kuwana;9. Kusanyungudika kana kusanyungudika mumvura.
Uv absorbers inogona kuiswa mumapoka anotevera maererano nemakemikari avo: salicylate esters, phenylketones, benzotriazoles, inotsiva acrylonitrile, triazines uye maamine akavharwa.

Kusuma chigadzirwa uye maitiro

Ultraviolet absorbent ndiyo inonyanya kushandiswa imwe mhando yechiedza stabilizer, zvichienderana nechimiro chayo inogona kukamurwa kuita salicylate esters, benzophenone, benzotriazole, inotsiva acrylonitrile, triazines, nezvimwewo, iyo indasitiri yekushandiswa kwebenzophenone yakawanda uye benzotriazole.Iyo quencher inonyanya kuita simbi yakaoma, yakadai se divalent nickel complex, kazhinji uye ultraviolet absorbent uye, synergistic effect, ultraviolet absorbent imhando yechiedza stabilizer, inogona kutora chiedza chezuva uye fluorescent chiedza muchikamu che ultraviolet, uye pachayo haishanduki.
Nekuti mwaranzi yezuva ine huwandu hukuru hwechiedza cheultraviolet chinokuvadza kuzvinhu zvine mavara, kureba kwaro kunosvika 290-460 nanometers, aya anokuvadza ultraviolet mwenje kuburikidza nekemikari Redox reaction, mamorekuru emavara anopedzisira aora uye kupera.
Kune zvese zvemuviri uye zvemakemikari nzira dzekudzivirira kukuvara kwemavara kubva kune inokuvadza UV mwenje.
Heino sumo pfupi yemakemikari nzira, ndiko kuti, kushandiswa kweUV absorbers kuchengetedza chinhu chinoshanda kudzivirira, kana kuderedza kuparadzwa kwayo kwemavara.

use

Inogona kunyatsotora ultraviolet chiedza ine wavelength ye270-380 nm, inonyanya kushandiswa polyvinyl chloride, polystyrene, unsaturated resin, polycarbonate, polymethyl methacrylate, polyethylene, ABS resin, epoxy resin uye cellulose resin, etc. Inokodzera photosensitive materials zvakadai sefirimu yemavara, firimu remavara, pepa remavara uye polymer, nezvimwe.Kuti kunyura kwakasimba, kushanda kwepamusoro ultraviolet absorber

pasuru uye chokufambisa

B. Ichi chigadzirwa chinogona kushandiswa,, 25KG, BAERRLS.
C. Chengetedza chakavharwa munzvimbo inotonhorera, yakaoma uye inofefetera mukati memba.Midziyo inofanira kuvharwa zvakasimba mushure mekushandiswa kwega kwega isati yashandiswa.
D. Ichi chigadzirwa chinofanira kuiswa chisimbiso zvakanaka panguva yekufambisa kudzivirira unyoro, alkali yakasimba uye asidi, mvura uye zvimwe tsvina kubva pakusanganiswa.
