Muaj hydrogen peroxide yog lwm oxide ntawm hydrogen dua li dej. Nws yog cov kua tsis muaj xim thiab pob tshab nrog cov qauv molecular ntawm H2O2. Nws cov viscosity siab dua me ntsis ntawm cov dej, thiab nws cov khoom siv tshuaj tsis ruaj khov. Feem ntau, nws yog khaws cia rau hauv daim ntawv ntawm 30 feem pua lossis 60 feem pua aqueous tov. Hydrogen peroxide muaj zog oxidizing zog thiab tsis muaj zog acidic.
Hauv kev tsim tshuaj lom neeg, hydrogen peroxide (hydrogen peroxide) yog siv los npaj cov peroxides (xws li sodium perborate, thiab peracetic acid), epoxy compounds, tshuaj, thiab lwm yam. Nws kuj yog siv rau kev kho cov dej khib nyiab, oxidation extrusion hauv cov khoom noj khoom haus. , starch Denaturants, preservatives, bactericidal, thiab lwm yam, thiab muaj peev xwm muaj oxidative los yog txo cov teebmeem nyob rau hauv ntau yam. Muaj oxidants, tshuaj dawb, tshuaj tua kab mob, tshuaj dechlorination, thiab rau foob pob ua ntxaij roj, organic lossis inorganic peroxides, ua npuas ncauj thiab lwm yam ntxeem tau.
1. Tsawg concentration (xws li 3 feem pua) muaj hydrogen peroxide, feem ntau yog siv rau kev ua kom tsis muaj menyuam thiab kev kho mob sab nraud, xws li tshuaj tua kab mob
2. Qhov zoo tshaj plaws piv rau kev kuaj ntshav: 6 feem pua hydrogen peroxide ntxiv rau 0.005 feem pua methylene xiav. Qhov kev sim yog siv los ua raw khoom rau kev ua O2.
3. Rau kev siv hauv kev lag luam (kwv yees li 10 feem pua rau ntau dua), nws yog siv hauv textile, tawv, ntawv, thiab ntoo tsim kev lag luam ua tshuaj dawb thiab deodorizing.
4. Hydrogen peroxide kuj yog ib qho ntawm cov khoom xyaw ntawm cov plaub hau dyes. Nws kuj yog siv los ua cov khoom siv rau kev sib txuas cov khoom siv raw khoom (catechol), tshuaj, tus neeg sawv cev kho mob hlau, polymerization pib, thiab lwm yam tuaj yeem siv los ua foob pob hluav taws.
Chemical synthesis: Initiator, foaming agent, plasticizer, raw khoom ntawm peroxide series khoom rau cov khoom yas, thiab lwm yam.
Ntawv Kev Lag Luam: Pulp Bleaching
Kev Lag Luam Textile: Khaub Ncaws Bleaching
Kev tiv thaiv ib puag ncig kev lag luam: dej phwj kho
Thaum koj siv nws, koj yuav tsum xyuam xim tshwj xeeb rau:
Explosive muaj zog oxidant. Hydrogen peroxide nws tus kheej tsis yog flammable, tab sis nws muaj peev xwm hnov mob nrog combustibles kom tso tawm ntau ntawm tshav kub thiab oxygen thiab ua rau hluav taws thiab tawg. Hydrogen peroxide yog qhov ruaj khov tshaj plaws ntawm pH 3.5 txog 4.5, yooj yim decomposed hauv alkaline kua, thiab tseem tuaj yeem decompose thaum raug lub teeb muaj zog, tshwj xeeb tshaj yog luv luv -yoj hluav taws xob. Thaum rhuab mus rau saum 100 degree, nws pib decompose sai heev.
Kev lag luam hydrogen peroxide yog ib qho muaj zog oxidant, uas tuaj yeem ua rau muaj kev sib daj sib deev los yog tawg txawm nyob rau hauv lub hnub ncaj qha los yog tov nrog impurities xws li hmoov av. Tsis tas li ntawd, ntev - kev sib cuag nrog cov khoom siv hluav taws xob xws li ntoo chips thiab fibers tuaj yeem ua rau muaj kev sib tsoo.
Kev lag luam hydrogen peroxide muaj tshuaj dawb thiab kub hnyiab ntawm daim tawv nqaij, thiab nws cov pa tuaj yeem ua rau lub qhov txhab thiab ua rau lub qhov ntswg thiab caj pas.
Nws tsim cov khoom tawg nrog ntau yam khoom siv xws li qab zib, hmoov txhuv nplej siab, cawv, roj av, thiab lwm yam, uas tuaj yeem tawg nyob rau hauv qhov kev ua ntawm kev cuam tshuam, kub lossis hluav taws xob. Thaum hydrogen peroxide los rau hauv kev sib cuag nrog ntau cov tshuaj inorganic los yog impurities, nws yuav sai sai decompose thiab ua rau tawg, tso tawm ntau heev ntawm tshav kub, oxygen thiab dej vapor.
Feem ntau cov hlau hnyav (xws li tooj liab, nyiaj, lead, mercury, zinc, cobalt, npib tsib xee, chromium, manganese, thiab lwm yam) thiab lawv cov oxides thiab ntsev yog cov khoom siv catalysts, thiab plua plav, luam yeeb tshauv, carbon hmoov, xeb, thiab lwm yam. kuj accelerate lub decomposition. Hydrogen peroxide ntawm qhov ntau tshaj 69 feem pua , nyob rau hauv ib lub thawv kaw nrog qhov tsim nyog ignition los yog qhov kub thiab txias, yuav tsim cov pa roj- theem tawg.
