chinonyudza chiedza che ultraviolet
Mazwi akafanana muChirungu
antioxidant
hunhu hwemakemikari
Chinonyungudutsa chiedza che ultraviolet imhando yechiedza chinosimbisa chiedza, chinogona kunyungudutsa chiedza chezuva nechiedza che fluorescent muchikamu che ultraviolet, asi icho pachacho hachichinji.
Nekuti mwaranzi yezuva ine chiedza cheultraviolet chakawanda chinokuvadza zvinhu zvine mavara, kureba kwaro kwehurefu kunosvika 290-460 nanometers, aya ma ultraviolet light anokuvadza kuburikidza nekemikari Redox reaction, mamorekuru emavara anozopedzisira aora uye apera.
Kune nzira dzemuviri nedzemakemikari dzekudzivirira kukuvara kwemavara kubva kuchiedza cheUV chinokuvadza.
Heino sumo pfupi yenzira yemakemikari, kureva kuti, kushandiswa kweUV absorbers kuchengetedza chinhu ichi kudzivirira zvinobudirira, kana kuderedza kuparadzwa kwacho kwemavara.
Zvishandiso zvinonyungudutsa UV zvinofanirwa kunge zvine mamiriro anotevera
(1) inogona kunwisa chiedza cheultraviolet zvakasimba (kunyanya kureba kwe 290-400nm); (2) Kugadzikana kwakanaka kwekupisa, kunyangwe mukugadzirisa hakuzochinji nekuda kwekupisa, kupisa kushoma; Kugadzikana kwakanaka kwemakemikari, hapana mhinduro yakaipa nezvikamu zvechinhu chiri muchigadzirwa; (4) Kusanganiswa kwakanaka, kunogona kupararira zvakaenzana muchinhu chacho, hapana chando, hapana exudation; (5) Kugadzikana kwe photochemical kwechinhu chinonyungudutsa mvura pachako kwakanaka, hakuori, hakuchinji ruvara; ⑥ Haina ruvara, haina chepfu, haina hwema; ⑦ haidzivirirwe pakusukwa mumvura; ⑧ Yakachipa uye iri nyore kuwana; 9. Hainyungudike kana isinganyungudike mumvura.
Zvinonyudza UV zvinogona kuiswa mumapoka anotevera zvichienderana nechimiro chazvo chemakemikari: salicylate esters, phenylketones, benzotriazoles, substituted acrylonitrile, triazines uye blocked amines.
Sumo yechigadzirwa uye maficha azvo
Ultraviolet absorbent ndiyo inonyanya kushandiswa mhando imwe yechiedza chinodzikamisa, zvichienderana nechimiro chayo inogona kukamurwa kuita salicylate esters, benzophenone, benzotriazole, substituted acrylonitrile, triazines, nezvimwewo, kushandiswa kwemaindasitiri kwebenzophenone yakawanda uye benzotriazole. Chinodzima moto chinonyanya kushandiswa nesimbi, senge divalent nickel complex, kazhinji uye ultraviolet absorbent uye, synergistic effect, ultraviolet absorbent rudzi rwechiedza chinodzikamisa, chinogona kupinza chiedza chezuva uye fluorescent light source muchikamu cheultraviolet, uye pachayo haishanduke.
Nekuti mwaranzi yezuva ine chiedza cheultraviolet chakawanda chinokuvadza zvinhu zvine mavara, kureba kwaro kwehurefu kunosvika 290-460 nanometers, aya ma ultraviolet light anokuvadza kuburikidza nekemikari Redox reaction, mamorekuru emavara anozopedzisira aora uye apera.
Kune nzira dzemuviri nedzemakemikari dzekudzivirira kukuvara kwemavara kubva kuchiedza cheUV chinokuvadza.
Heino sumo pfupi yenzira yemakemikari, kureva kuti, kushandiswa kweUV absorbers kuchengetedza chinhu ichi kudzivirira zvinobudirira, kana kuderedza kuparadzwa kwacho kwemavara.
shandisa
Inogona kupinza chiedza che ultraviolet zvinobudirira ne wavelength ye 270-380 nm, inonyanya kushandiswa pa polyvinyl chloride, polystyrene, unsaturated resin, polycarbonate, polymethyl methacrylate, polyethylene, ABS resin, epoxy resin uye cellulose resin, nezvimwewo. Yakakodzera zvinhu zvinonzwa chiedza zvakaita se color film, color film, color paper uye polymer, nezvimwewo. Yakakodzera zvakanyanya zvigadzirwa zvisina ruvara uye zvakajeka; Yekupinza kwakasimba, ultraviolet absorber inoshanda zvakanyanya.
pasuru uye kutakurwa
B. Chigadzirwa ichi chinogona kushandiswa,,25KG，BAERRLS。
C. Chengeta yakavharwa munzvimbo inotonhorera, yakaoma uye ine mhepo mukati. Midziyo inofanira kuvharwa zvakasimba mushure mekushandisa kwega kwega usati washandisa.
D. Chigadzirwa ichi chinofanira kuvharwa zvakanaka panguva yekufambisa kudzivirira hunyoro, alkali yakasimba uye acid, mvura nezvimwe tsvina kuti zvisasanganiswe.
