izici zamakhemikhali

I-Absorber ye-Ultraviolet iwuhlobo lwe-stabilizer yokukhanya, ingakwazi ukumunca ukukhanya kwelanga nomthombo wokukhanya we-fluorescent engxenyeni ye-ultraviolet, kodwa yona ngokwayo ayishintshi.
Ngenxa yokuthi imisebe yelanga iqukethe inani elikhulu lokukhanya kwe-ultraviolet okuyingozi ezintweni ezinemibala, ubude bayo bendawo bucishe bube ngama-nanometer angu-290-460, lokhu kukhanya kwe-ultraviolet okuyingozi ngokusabela kwekhemikhali i-Redox, ama-molecule ombala ekugcineni abole futhi afiphale.
Kukhona kokubili izindlela ezingokwenyama nezamakhemikhali zokuvimbela ukulimala kombala ekukhanyeni okuyingozi kwe-UV.
Nasi isingeniso esifushane sendlela yamakhemikhali, okungukuthi, ukusetshenziswa kwe-UV absorbers ukuvikela into ephumelelayo yokuvimbela, noma ukwenza buthaka ukubhujiswa kwayo kombala.
Ama-absorber ama-Uv kufanele abe nezimo ezilandelayo
(1) ingakwazi ukumunca ukukhanya kwe-ultraviolet (ikakhulukazi ubude begagasi obungu-290-400nm);(2) Ukuzinza okuhle kokushisa, ngisho nasekucubunguleni ngeke kushintshe ngenxa yokushisa, ukuguquguquka kokushisa kuncane;Ukuzinza okuhle kwamakhemikhali, akukho ukusabela okubi ngezingxenye ezibonakalayo zomkhiqizo;(4) Ukungahleleki kahle, kungahlakazeka ngokulinganayo endabeni, akukho sithwathwa, akukho exudation;(5) Ukuzinza kwe-photochemical of the absorbent ngokwayo kuhle, akuboli, akushintshi umbala;⑥ Ayinambala, ayinabuthi, ayinaphunga;⑦ ukumelana nokugeza emanzini;⑧ Kushibhile futhi kulula ukukuthola;9. Ayincibiliki noma ayincibiliki emanzini.
Izimunyisi ze-Uv zingahlukaniswa zibe amaqembu alandelayo ngokwesakhiwo sawo samakhemikhali: i-salicylate esters, i-phenylketones, i-benzotriazoles, i-acrylonitrile efakwe esikhundleni, i-triazines nama-amine avinjiwe.

Isingeniso somkhiqizo kanye nezici

I-Absorbent ye-Ultraviolet iwuhlobo olulodwa lokuqiniswa kokukhanya olusetshenziswa kakhulu, ngokusho kwesakhiwo sayo ingahlukaniswa i-salicylate esters, i-benzophenone, i-benzotriazole, i-acrylonitrile esikhundleni, i-triazines, njll., ukusetshenziswa kwezimboni kwe-benzophenone ne-benzotriazole kakhulu.I-quencher ngokuyinhloko iyinkimbinkimbi yensimbi, njenge-divalent nickel complex, imvamisa kanye ne-ultraviolet absorbent futhi, umphumela we-synergistic, i-ultraviolet absorbent iwuhlobo lokuqiniswa kokukhanya, ingakwazi ukumunca ukukhanya kwelanga nomthombo wokukhanya we-fluorescent engxenyeni ye-ultraviolet, futhi ngokwayo ayishintshi.
Ngenxa yokuthi imisebe yelanga iqukethe inani elikhulu lokukhanya kwe-ultraviolet okuyingozi ezintweni ezinemibala, ubude bayo bendawo bucishe bube ngama-nanometer angu-290-460, lokhu kukhanya kwe-ultraviolet okuyingozi ngokusabela kwekhemikhali i-Redox, ama-molecule ombala ekugcineni abole futhi afiphale.
Kukhona kokubili izindlela ezingokwenyama nezamakhemikhali zokuvimbela ukulimala kombala ekukhanyeni okuyingozi kwe-UV.
Nasi isingeniso esifushane sendlela yamakhemikhali, okungukuthi, ukusetshenziswa kwe-UV absorbers ukuvikela into ephumelelayo yokuvimbela, noma ukwenza buthaka ukubhujiswa kwayo kombala.

sebenzisa

Ingakwazi ukumunca kahle ukukhanya kwe-ultraviolet ngobude begagasi obungu-270-380 nm, ikakhulukazi esetshenziselwa i-polyvinyl chloride, i-polystyrene, i-resin unsaturated, i-polycarbonate, i-polymethyl methacrylate, i-polyethylene, i-ABS resin, i-epoxy resin ne-cellulose resin, njll. Ifanele izinto ezizwela ukukhanya njengefilimu yombala, ifilimu yombala, iphepha lombala kanye ne-polymer, njll. Ifaneleka ngokukhethekile emikhiqizweni esobala nekhanyayo engenambala;Ukuze uthole ukumuncwa okuqinile, ukusebenza okuphezulu kwe-ultraviolet absorber

iphakethe kanye nezokuthutha

B. Lo mkhiqizo ungasetshenziswa,, 25KG, BAERRLS.
C. Gcina kuvaliwe endlini epholile, eyomile futhi engenamoya.Iziqukathi kufanele zivalwe ngokuqinile ngemva kokusetshenziswa ngakunye ngaphambi kokusetshenziswa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuthutha ukuvimbela umswakama, i-alkali enamandla ne-asidi, imvula nokunye ukungcola ekuxubeni.
