Ua kom muaj zog: 30 Kcal / mol
10-teev ib nrab-lub neej kub: 73 ℃
1-teev ib nrab-lub neej kub: 92 ℃
1-feeb ib nrab-lub neej kub: 131 ℃
Mib app:Nws yog siv los ua monomer polymerization pib ntawm PVC, unsaturated polyester, polyacrylate, tab sis kuj yog siv los ua tus neeg sawv cev sib txuas ntawm polyethylene, thiab siv los ua tus neeg sawv cev ntawm unsaturated polyester resin, siv los ua tshuaj reagent, oxidant thiab tshuaj dawb;Raws li cov hmoov nplej zoo, nws muaj cov kab mob bactericidal thiab muaj zog oxidation nyhuv, ua rau hmoov bleaching.
Ntim:20 Kg, 25 Kg, sab hauv PE hnab, cov thawv sab nraud lossis cov thawv ntim khoom ntim, thiab qis dua 35 ℃ yog khaws cia rau hauv qhov chaw txias thiab qhov cua.Nco tseg: Khaws lub pob ntim, nco ntsoov kom poob dej, thiab ua rau muaj kev phom sij.
Cov kev cai thauj mus los:Benzoyl peroxide belongs rau thawj cov organic oxidant.Risk No.: 22004. Lub thawv yuav tsum cim nrog "organic peroxide" thiab yuav tsum tsis txhob muaj cov neeg caij tsheb.
Cov yam ntxwv txaus ntshai:Hauv cov organic teeb meem, txo tus neeg sawv cev, leej faj, phosphorus thiab qhib nplaim taws, lub teeb, cuam tshuam, kub kub combustible;combustion stimulation pa luam yeeb.
Kev ntsuas hluav taws kub:Thaum hluav taws kub, hluav taws yuav tsum tua nrog dej ntawm qhov chaw tawg.Thaum muaj hluav taws kub nyob ib ncig ntawm cov tshuaj no, cia lub thawv txias nrog dej.Hauv qhov hluav taws kub loj, thaj chaw hluav taws yuav tsum tau khiav tawm tam sim ntawd.Kev ntxuav thiab cawm txoj haujlwm tom qab hluav taws yuav tsum tsis txhob ua ua ntej cov peroxide txias tag.Nyob rau hauv rooj plaub uas tshwm sim los ntawm hluav taws kub los yog siv, cov to yuav tsum tau tov nrog dej ntub dej vermiculite, ntxuav (tsis muaj hlau los yog fiber ntau cov cuab yeej), thiab muab tso rau hauv ib lub thawv yas rau kev kho tam sim ntawd.
Pom zoo txoj kev pov tseg pov tseg:Pretreatment muaj decomposition nrog natridium hydroxide.Thaum kawg, biodegradable sodium benzene (formate) tov yog poured rau hauv lub ntws.Kev kho ntau npaum li cas yuav tsum tau kho pH ua ntej tso rau hauv cov kav dej, lossis tom qab sib tov nrog cov roj tsis muaj roj, kom tswj tau qhov hluav taws kub.Cov thawv khoob ntawm peroxides yuav tsum tau hlawv ntawm qhov deb lossis ntxuav nrog 10% NaOH tov.
