Txawm hais tias nws yog cov xim av cawv uas tawv ncauj ntawm koj lub tsho nyiam lossis cov ntaub pua chaw uas tsis muaj xim, sodium persulfate tuaj yeem daws cov teeb meem no tau yooj yim.

Tsis tas li ntawd xwb, sodium persulfate muaj cov yam ntxwv oxidizing muaj zog. Qhov no ua rau nws zoo tagnrho rau kev pab hauv cov tshuaj lom neeg uas xav tau kev tshem tawm cov electrons. Hauv cov lag luam uas vam khom ntau rau cov txheej txheem oxidation, xws li kev tsim cov tshuaj thiab cov xim, sodium persulfate ua pov thawj tias yog ib qho khoom muaj nqis tsis muaj nqis.

Tsis tas li ntawd xwb, cov tshuaj no kuj ua haujlwm ua tus txhawb nqa emulsion polymerization. Rau cov neeg tsis paub txog lo lus, emulsion polymerization txhais tau hais tias yog cov txheej txheem ntawm kev tsim cov polymers hauv cov dej nruab nrab. Sodium persulfate ua haujlwm ua tus catalyst, pab txhawb kev tsim cov polymers no. Cov lag luam siv emulsion polymerization, xws li cov nplaum thiab cov txheej txheem pleev xim, vam khom sodium persulfate rau nws qhov ua tau zoo hauv kev ua tiav cov txiaj ntsig xav tau.

Qhov xwm txheej ntawm sodium persulfate ntau yam yog qhov ua rau nws txawv ntawm lwm cov tshuaj. Nws lub peev xwm ua haujlwm ua tus neeg sawv cev dawb thiab tus neeg sawv cev oxidant ua rau nws yog qhov kev xaiv zoo rau ntau yam kev lag luam. Tsis tas li ntawd, nws cov khoom emulsion polymerization txhawb nqa ntxiv nthuav dav nws qhov kev siv.

Ntxiv rau nws cov kev siv ntau yam, sodium persulfate muaj ntau yam ntxwv sib txawv. Nws cov dej yaj ua rau nws cov txiaj ntsig zoo li cov tshuaj dawb thiab cov tshuaj oxidant, ua rau nws yooj yim yaj thiab cuam tshuam nrog lwm yam tshuaj. Ntawm qhov tod tes, nws cov insolubility hauv ethanol tiv thaiv nws los ntawm kev cuam tshuam nrog cov txheej txheem uas vam khom ethanol ua cov kuab tshuaj.

Yuav kom siv tau sodium persulfate zoo tshaj plaws, yuav tsum xav txog tej yam tseem ceeb. Kev ceev faj thiab ua raws li cov lus qhia kev nyab xeeb yog qhov tseem ceeb vim nws muaj peev xwm ua rau muaj kev phom sij. Ntxiv mus, kev siv tshuaj sodium persulfate kom raug yog qhov tseem ceeb thaum siv sodium persulfate rau hauv txhua txoj kev, txawm tias yog kev ua kom dawb, kev ua kom oxidation, lossis kev ua kom emulsion polymerization.

Kev ceev faj ua haujlwm:Kev ua haujlwm kaw, txhawb kom muaj cua nkag. Cov neeg ua haujlwm yuav tsum tau kawm tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm. Nws raug pom zoo kom cov neeg ua haujlwm hnav lub hau npog-hom hluav taws xob lim cua tiv thaiv plua plav, khaub ncaws tiv thaiv polyethylene, thiab hnab looj tes roj hmab. Khaws cia kom deb ntawm hluav taws thiab cua sov. Tsis txhob haus luam yeeb hauv chaw ua haujlwm. Tsis txhob tsim cov plua plav. Tsis txhob kov cov neeg sawv cev txo qis, cov hmoov hlau nquag, alkalis, cawv. Thaum tuav, yuav tsum tau thauj khoom me me thiab tshem tawm kom tiv thaiv kev puas tsuaj rau cov ntim khoom thiab cov thawv. Tsis txhob poob siab, cuam tshuam thiab sib txhuam. Nruab nrog ntau yam thiab ntau npaum li cas ntawm cov khoom siv tua hluav taws thiab cov khoom siv kho mob thaum muaj xwm txheej xau. Cov thawv khoob yuav muaj cov khoom seem tsis zoo.

Kev ceev faj txog kev khaws cia:Khaws cia rau hauv qhov chaw txias, qhuav thiab muaj cua nkag zoo. Khaws cia kom deb ntawm hluav taws thiab cua sov. Qhov kub ntawm lub thawv yuav tsum tsis pub tshaj 30 ℃, thiab qhov av noo yuav tsum tsis pub tshaj 80%. Lub pob khoom raug kaw.
