Ukuqaliswa kwe-Optical brightener OB-1
I-Optical brightener OB-1,2,2- (4,4-distyreneyl) dibenzoxazole yinto etyheli yekristale enendawo yokunyibilika ye-359-362 ℃. Ayinyibiliki emanzini, ayinavumba, kwaye inomsebenzi ozinzile. Obona bude buphezulu be-spectrum yokufunxa yi-374nm, kwaye ine-fluorescence eyomeleleyo ene-fluorescence emission wavelength ye-434nm. I-Optical brightener i-OB-1 yi-optical brightener esebenzayo esetyenziselwa iifayili ze-polyester, kwaye isetyenziswa ngokubanzi kwiiplastiki ezifana ne-ABS, i-PS, i-HIPS, i-PC, i-PP, i-PE, i-EVA, kunye ne-PVC enzima. Inesiphumo esihle kakhulu sokwenza mhlophe, uzinzo oluhle kakhulu lwe-thermal, kunye nokongezwa okuncinci.
Izikhanyisi zamehlo zinokufunxa ukukhanya okungabonakaliyo kwe-ultraviolet (kunye noluhlu lwamaza obude obumalunga ne-360-380nm) kwaye luguqule lube kubude obude obuluhlaza okwesibhakabhaka okanye kukukhanya okumfusa okubonakalayo, ngaloo ndlela kuhlawulela umthubi kancinane ongafunwayo kwimatrix. Kwangaxeshanye, babonakalisa ukukhanya okubonakalayo ngakumbi kunobude bomda besiganeko sokuqala kuluhlu lwe-400-600nm, okwenza imveliso ibonakale imhlophe, iqaqambile, yaye idlamkile.
Ukusetyenziswa kwe-Optical brightener OB-1
Le mveliso ifanelekile ukuba ibe mhlophe kwaye ikhanyise iiplastiki ezifana ne-PVC, i-PE, i-PP, i-ABS, i-PC, i-PA, njl. Le mveliso inetyhefu ephantsi kakhulu kwaye ingasetyenziselwa ukwenza mhlophe iiplastiki ezisetyenziselwa ukupakishwa kokutya kunye nezinto zokudlala zabantwana. Inokongezwa ngexesha lokwenziwa kwe-post-processing okanye i-polymerization, kwaye izinto ezimhlophe zinobumhlophe obuphezulu kunye nobushushu obugqwesileyo kunye nokumelana nemozulu. I-OB-1 isenokwenziwa ibe yintlama yokwenza mhlophe i-textile.
Izinto ezilungileyo ze-Optical brightener OB-1
1.Ngokwembono yokumelana nobushushu:
I-Optical brightener i-OB-1 inendawo yokunyibilika engaphezu kwama-350 ℃ kwaye ngoku yeyona ikwaziyo ukumelana nobushushu phakathi kwazo zonke iimveliso zokukhanya okukhanyayo. Kubaphathi abavelisa iiplastiki ezinobushushu obuphezulu, i-optical brightener OB-1 ifanelekile ngakumbi.
Njengoko kusaziwa, ishishini leplastiki lishishini elibanzi nelohlukeneyo elineentlobo ezininzi kunye neempawu. Iqondo lobushushu lenkqubo yokuvelisa uninzi lweemveliso zeplastiki liphezulu, ezinye zide zifikelele kuma 300 degrees celcius. Okwangoku, kuphela i-Optical brightener i-OB-1 inokumelana nobushushu obuphezulu obunjalo, nto leyo eyinzuzo ye-optical brightener OB-1.
2. Ukuqwalasela isibane sefluorescent esikhutshwayo
Iimveliso ezahlukeneyo zokuqaqambisa kwamehlo zinemibala eyahlukeneyo, ezinye izikhanyisi ze-optical zikhupha ukukhanya okuluhlaza okwesibhakabhaka, ngelixa ezinye zikhupha ukukhanya okuluhlaza okwesibhakabhaka. Uninzi lwezinto eziluhlaza kwindalo zityheli, kwaye ukukhanya okutyheli kudityaniswe nokukhanya okuluhlaza kuvelisa ukukhanya okumhlophe. Ke ngoko, izikhanyisi zamehlo ezinokukhanya okuluhlaza okuthe kratya zine-fluorescence engcono kunye neziphumo ezimhlophe, kwaye isixa esongeziweyo sincinci.
I-Optical brightener i-OB-1 inokwahlulwa ibe yinqanaba eliluhlaza kunye nesigaba esiphuzi ngokwembonakalo. I-fluorescence ekhutshwa sisigaba esiluhlaza sithambekele ekukhanyeni okuluhlaza okwesibhakabhaka, ngelixa i-fluorescence ekhutshwa sisigaba esimthubi sithambekele ekukhanyeni okuluhlaza okwesibhakabhaka. Ke ngoko, kungenxa yoko le nto uninzi lwabathengi bekhetha isigaba esiluhlaza se-Optical brightener OB-1 kule mihla.
