iimpawu zekhemikhali

I-Absorber ye-Ultraviolet luhlobo lwe-stabilizer yokukhanya, inokuthatha ukukhanya kwelanga kunye nomthombo wokukhanya kwe-fluorescent kwindawo ye-ultraviolet, kodwa yona ngokwayo ayitshintshi.
Ngenxa yokuba imitha yelanga inesixa esikhulu sokukhanya kwe-ultraviolet okuyingozi kwizinto ezinemibala, ubude bayo bumalunga nama-290-460 nanometers, oku kukhanya kwe-ultraviolet kuyingozi ngokusabela kwekhemikhali iRedox, iimolekyuli zemibala ekugqibeleni zibole kwaye ziphele.
Kukho zombini iindlela zomzimba kunye neekhemikhali zokuthintela umonakalo wombala kwisibane esiyingozi se-UV.
Nantsi intshayelelo emfutshane kwindlela yemichiza, oko kukuthi, ukusetyenziswa kwe-UV absorbers ukukhusela into esebenzayo yokuthintela, okanye ukunciphisa ukutshatyalaliswa kwayo kombala.
Izithambisi zeUv kufuneka zibe nezi meko zilandelayo
(1) inokuthatha ngamandla ukukhanya kwe-ultraviolet (ingakumbi ubude be-290-400nm);(2) Uzinzo oluhle lwe-thermal, nakwi-processing aluyi kutshintsha ngenxa yobushushu, ukuguquguquka kobushushu kuncinci;Uzinzo oluhle lweekhemikhali, akukho mpendulo imbi kunye nezinto eziphathekayo kwimveliso;(4) Ukungahambi kakuhle, kunokuhlakazwa ngokulinganayo kwizinto eziphathekayo, akukho qabaka, akukho kukhutshwa;(5) Ukuzinza kwefotochemical ye-absorbent ngokwayo ilungile, ayiboli, ayitshintshi umbala;⑥ Ayinambala, ayinatyhefu, ayinavumba;⑦ ukuxhathisa ukuhlamba emanzini;⑧ Itshiphu kwaye kulula ukuyifumana;9. Ukunganyibiliki okanye ukunganyibiliki emanzini.
I-Uv absorbers ingahlelwa ngokwala maqela alandelayo ngokwesakhiwo sawo samachiza: i-salicylate esters, i-phenylketones, i-benzotriazoles, i-acrylonitrile efakwe endaweni, i-triazines kunye nee-amine ezivaliweyo.

Intshayelelo yemveliso kunye neempawu

I-Absorbent ye-Ultraviolet yeyona nto isetyenziswa kakhulu uhlobo olulodwa lwe-stabilizer yokukhanya, ngokwesakhiwo sayo sinokwahlulwa sibe yi-salicylate esters, i-benzophenone, i-benzotriazole, i-acrylonitrile efakwe endaweni, i-triazines, njl., ukusetyenziswa kwemizi-mveliso yeyona benzophenone kunye ne-benzotriazole.I-quencher ngokuyinhloko i-metal complex, efana ne-divalent nickel complex, ngokuphindaphindiweyo kunye ne-ultraviolet absorbent kunye, i-synergistic effect, i-absorbent ye-ultraviolet luhlobo oluthile lwe-stabilizer yokukhanya, inokuthatha ukukhanya kwelanga kunye nomthombo wokukhanya kwe-fluorescent kwindawo ye-ultraviolet, kwaye ngokwayo ayitshintshi.
Ngenxa yokuba imitha yelanga inesixa esikhulu sokukhanya kwe-ultraviolet okuyingozi kwizinto ezinemibala, ubude bayo bumalunga nama-290-460 nanometers, oku kukhanya kwe-ultraviolet kuyingozi ngokusabela kwekhemikhali iRedox, iimolekyuli zemibala ekugqibeleni zibole kwaye ziphele.
Kukho zombini iindlela zomzimba kunye neekhemikhali zokuthintela umonakalo wombala kwisibane esiyingozi se-UV.
Nantsi intshayelelo emfutshane kwindlela yemichiza, oko kukuthi, ukusetyenziswa kwe-UV absorbers ukukhusela into esebenzayo yokuthintela, okanye ukunciphisa ukutshatyalaliswa kwayo kombala.

sebenzisa

Iyakwazi ukufunxa ngokufanelekileyo ukukhanya kwe-ultraviolet kunye ne-wavelength ye-270-380 nm, isetyenziselwa i-polyvinyl chloride, i-polystyrene, i-resin unsaturated, i-polycarbonate, i-polymethyl methacrylate, i-polyethylene, i-ABS resin, i-epoxy resin kunye ne-cellulose resin, njl. njengefilimu yombala, ifilimu yombala, iphepha lombala kunye ne-polymer, njl.Ukufunxa ngamandla, ukusebenza okuphezulu kwe-ultraviolet absorber

iphakheji kunye nezithuthi

B. Le mveliso ingasetyenziswa,, 25KG, BAERRLS.
C. Gcina uvalelwe kwindawo epholileyo, eyomileyo nengena umoya ngaphakathi.Imigqomo kufuneka ivalwe ngokuqinileyo emva kokusetyenziswa ngakunye phambi kokusetyenziswa.
D. Le mveliso kufuneka ivalwe kakuhle ngexesha lokuthutha ukukhusela umswakama, i-alkali enamandla kunye ne-asidi, imvula kunye nezinye izinto ezingcolileyo ekuxubeni.
