Izici zamakhemikhali

I-Ultraviolet Absorber uhlobo lokukhanya okukhanyayo, lungadonsa ukukhanya kwelanga nomthombo wokukhanya we-fluorescent engxenyeni ye-ultraviolet, kepha ngokwayo ayishintshi.
Ngoba imisebe yelanga iqukethe inani elikhulu le-ultraviolet light elinengozi ezintweni ezinemibala, i-wavelength yayo maqondana nama-290-460 ama-nanometers, lokhu kukhanya okulimazayo ngokukhanyisa ukusabela kwe-redox yamakhemikhali, ama-molecule anemibala ekugcineni abola futhi aphela.
Kunezindlela zombili nezemakhemikhali zokuvimbela ukulimala kombala kusuka ekukhanyiseni okuyingozi kwe-UV.
Nasi isingeniso esifushane sendlela yamakhemikhali, okungukuthi, ukusetshenziswa kwama-UV athinta ukuvikela ukuvimbela okusebenzayo, noma ukwenza buthaka ukucekelwa phansi kombala.
Ama-UV Able kufanele abe nezimo ezilandelayo
(1) ingadonsa kanzima i-ultraviolet ukukhanya (ikakhulukazi i-wavelength ka-290-400nm); (2) Ukuqina okuhle okushisayo, ngisho nasekusebenzeni ngeke kuguquke ngenxa yokushisa, ukuguquguquka kokushisa kuncane; Ukuqina okuhle kwamakhemikhali, akukho ukusabela okuphikisayo ngezinto ezibonakalayo emkhiqizweni; (4) Okuhle Okuhle, kungahlakazwa ngokulinganayo kokuqukethwe, akukho sithwathwa, akukho kudingiswa; (5) Ukuqina kwe-Photochemical komoya uqobo kulungile, akuboli, akushintshi umbala; ⑥ angenamzimba, awunalo ubuthi, obunephunga; ⑦ Ukumelana nokuhlanza ukucwilisa; ⑧ eshibhile futhi kulula ukuyithola; 9. I-insoluble noma insoluble emanzini.
Ama-UV Ablembo angahlukaniswa emaqenjini alandelayo ngokuya ngesakhiwo sawo samakhemikhali: ama-phenyllones, ama-benzotriazoles, afakwe esikhundleni sakwa-acrylonitrile, ama-triazines kanye nemigqa evinjiwe.

Ukwethulwa komkhiqizo nezici

I-Ultraviolet Absorbent iyindlela eyodwa esetshenziswa kakhulu i-stabilizer yokukhanya, ngokuya ngesakhiwo sayo ingahlukaniswa ngama-salicylate esters, i-benzophenone, i-acryotritrile, i-acrylonitriterile, i-acryonitrise, njll. I-Quencher ikakhulukazi iyinkimbinkimbi yensimbi, efana ne-udididi ye-nickel eyinkimbinkimbi, imvamisa futhi, umphumela we-ultraviolet, umthondo we-ultraviolet uhlobo lokukhanya kwelanga nengxenye ye-fluorescent engxenyeni ye-ultraviolet, futhi ngokwayo ayishintshi.
Ngoba imisebe yelanga iqukethe inani elikhulu le-ultraviolet light elinengozi ezintweni ezinemibala, i-wavelength yayo maqondana nama-290-460 ama-nanometers, lokhu kukhanya okulimazayo ngokukhanyisa ukusabela kwe-redox yamakhemikhali, ama-molecule anemibala ekugcineni abola futhi aphela.
Kunezindlela zombili nezemakhemikhali zokuvimbela ukulimala kombala kusuka ekukhanyiseni okuyingozi kwe-UV.
Nasi isingeniso esifushane sendlela yamakhemikhali, okungukuthi, ukusetshenziswa kwama-UV athinta ukuvikela ukuvimbela okusebenzayo, noma ukwenza buthaka ukubhujiswa kwalo kombala

umsebenzi

Kungadonsa ngempumelelo ukukhanya kwe-ultraviolet nge-wavelength ka-270-380 nm, ikakhulukazi esetshenziselwa i-polyvinyl chloride, i-polystylle, i-resin engekho emthethweni, i-polyethylene, i-abs resin, njll. Ilungele izinto ezibonakalayo njengemibala yefilimu, imibala yefilimu, iphepha lombala kanye ne-polymer, njll. Ngokumuncwa ngokuqinile, ukusebenza okuphezulu kwe-Ultraviolet Absorber

iphakheji nokuhamba

B. Lo mkhiqizo ungasetshenziswa ,, 25kg, ama-Baerrs.
C. Isitolo esivalwe ngendawo epholile, eyomile futhi enomoya ongena ngaphakathi. Iziqukathi kufanele zivalwe ngokuqinile ngemuva kokusetshenziswa ngakunye ngaphambi kokusebenzisa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuhamba ukuvikela umswakama, i-alkali ne-acid, imvula nokunye ukungcola okukuxubana.
