iimpawu zeekhemikhali

I-ultraviolet absorber luhlobo lwe-light stabilizer, inokufunxa ukukhanya kwelanga kunye nomthombo wokukhanya kwe-fluorescent kwinxalenye ye-ultraviolet, kodwa yona ayitshintshi.
Ngenxa yokuba imisebe yelanga inesixa esikhulu sokukhanya kwe-ultraviolet okuyingozi kwizinto ezinemibala, ubude bayo bumalunga ne-290-460 nanometers, ezi zikhanyiso ze-ultraviolet eziyingozi ngokusebenzisa i-chemical Redox reaction, iimolekyuli zombala ekugqibeleni ziyabola kwaye ziphele.
Kukho iindlela ezibonakalayo nezekhemikhali zokuthintela umonakalo wombala ekukhanyeni okuyingozi kwe-UV.
Nantsi intshayelelo emfutshane kwindlela yamachiza, oko kukuthi, ukusetyenziswa kwezifunxi ze-UV ukukhusela into ngendlela esebenzayo yokuthintela, okanye ukunciphisa ukutshatyalaliswa kwayo kombala.
Izifunxi ze-UV kufuneka zibe nezi meko zilandelayo
(1) inokufunxa kakhulu ukukhanya kwe-ultraviolet (ingakumbi ubude bomda obuyi-290-400nm); (2) Uzinzo oluhle lobushushu, nokuba kusetyenzwa aluyi kutshintsha ngenxa yobushushu, ukuguquguquka kobushushu kuncinci; Uzinzo oluhle lweekhemikhali, akukho mpendulo imbi ngezinto ezikwimveliso; (4) Ukuxubana okulungileyo, kunokusasazeka ngokulinganayo kwizinto, akukho frost, akukho exudation; (5) Uzinzo lwe-photochemical lwe-absorbent ngokwayo lulungile, aluboli, alutshintshi umbala; ⑥ Ayinambala, ayinatyhefu, ayinavumba; ⑦ ayixhathisi ekuhlanjweni ngamanzi; ⑧ Ixabiso eliphantsi kwaye kulula ukuyifumana; 9. Ayinyibiliki okanye ayinyibiliki emanzini.
Izifunxi ze-UV zinokwahlulwa zibe ngamaqela alandelayo ngokwesakhiwo sazo seekhemikhali: ii-salicylate esters, ii-phenylketones, ii-benzotriazoles, ii-acrylonitrile ezitshintshiweyo, ii-triazines kunye nee-amines ezivaliweyo.

Intshayelelo yemveliso kunye neempawu zayo

I-ultraviolet absorbent yeyona isetyenziswa kakhulu kuhlobo olunye lwe-light stabilizer, ngokwesakhiwo sayo ingahlulwahlulwa ibe yi-salicylate esters, i-benzophenone, i-benzotriazole, i-acrylonitrile ethathelwe indawo, ii-triazines, njl.njl., ukusetyenziswa kwe-benzophenone kunye ne-benzotriazole kusetyenziswa kakhulu kwimizi-mveliso. I-quencher ikakhulu yi-metal complex, efana ne-divalent nickel complex, idla ngokufunxa i-ultraviolet kwaye, isiphumo se-synergistic, i-ultraviolet absorbent luhlobo lwe-light stabilizer, inokufunxa ukukhanya kwelanga kunye nomthombo wokukhanya we-fluorescent kwinxalenye ye-ultraviolet, kwaye ngokwayo ayitshintshi.
Ngenxa yokuba imisebe yelanga inesixa esikhulu sokukhanya kwe-ultraviolet okuyingozi kwizinto ezinemibala, ubude bayo bumalunga ne-290-460 nanometers, ezi zikhanyiso ze-ultraviolet eziyingozi ngokusebenzisa i-chemical Redox reaction, iimolekyuli zombala ekugqibeleni ziyabola kwaye ziphele.
Kukho iindlela ezibonakalayo nezekhemikhali zokuthintela umonakalo wombala ekukhanyeni okuyingozi kwe-UV.
Nantsi intshayelelo emfutshane kwindlela yamachiza, oko kukuthi, ukusetyenziswa kwezifunxi ze-UV ukukhusela into ngendlela esebenzayo yokuthintela, okanye ukunciphisa ukutshatyalaliswa kwayo kombala.

sebenzisa

Ingafunxa ngempumelelo ukukhanya kwe-ultraviolet ngobude be-270-380 nm, esetyenziswa kakhulu kwi-polyvinyl chloride, i-polystyrene, i-unsaturated resin, i-polycarbonate, i-polymethyl methacrylate, i-polyethylene, i-ABS resin, i-epoxy resin kunye ne-cellulose resin, njl. Ifanelekile kwizinto ezibonisa ukukhanya ezifana nefilimu yombala, ifilimu yombala, iphepha lombala kunye ne-polymer, njl. Ifanelekile ngokukodwa kwiimveliso ezingenambala nezikhanyayo; Kwi-absorber enamandla, i-ultraviolet absorber esebenza kakuhle.

iphakheji kunye nothutho

B. Le mveliso ingasetyenziswa,,25KG，BAERRLS。
C. Gcina ivalwe kwindawo epholileyo, eyomileyo nengena umoya ngaphakathi. Izikhongozeli mazivalwe kakuhle emva kokusetyenziswa ngakunye ngaphambi kokusetyenziswa.
D. Le mveliso kufuneka ivalwe kakuhle ngexesha lokuthuthwa ukuze kuthintelwe ukufuma, i-alkali enamandla kunye ne-asidi, imvula kunye nezinye izinto ezingcolileyo ukuba zingaxubeki.
