Kev ntsuas kev ua tau zoo ntawm Activated Alumina Pore Size
Apr 07, 2022
Tam sim no, peb yuav tsum tsis tsuas yog ua kom ceev kev lag luam sai, tab sis kuj sim lub cev lub zog ntawm inert activated alumina thiab pore loj activated alumina nyob rau hauv cov nqe lus ntawm dej nqus, acid tsis kam, alkali tsis kam, compressive zog thiab dej nqus, feem ntau nyob rau hauv cov nqe lus ntawm dej nqus. cov kev cai ntawm cov txheej txheem kev ntsuas kev lag luam rau pore loj zog ntawm activated alumina (Hg / t3210-2008), Nws tseem yuav tsum tau ua kom peb ib puag ncig ib puag ncig haum rau peb cov tib neeg ciaj sia. Qhov hluav taws kub tsis kam yog kuaj hauv txoj kev sim rau hluav taws kub tsis kam ntawm refractories (GB / t7322-2007), thiab lub ntuj hnyav load softening kub yog kuaj raws li txoj kev sim rau load softening kub txawv cua sov txoj kev (GB / t5989-2008 ). Luv luv piav qhia txog lub ntsiab sab hauv thiab kev ua haujlwm ntawm phaj ntauwd. Xa mus rau txoj kev sim hardness ntawm cov khoom siv ceramic (gb3297-82) rau Mohs hardness test. Ntxiv nrog rau kev sim raws li cov txheej txheem tau teev tseg hauv cov qauv kev lag luam hauv tebchaws lossis cov qauv hauv tebchaws, peb tsuas muaj ib lub ntiaj teb uas yuav tsum muaj kev tiv thaiv zoo raws li cov xwm txheej tshwj xeeb. Cov khoom ntawm activated alumina thiab pore loj activated alumina kuj tuaj yeem ntsuas los ntawm cov hauv qab no,
Lub hom phiaj ntawm kev tso dej yog txhawm rau tshem tawm cov av xoob xws li plua plav, sediment, poob algae thiab cov khoom noj rotten hauv lub cev nrog cov dej ntws loj ntau li ntau tau, thiab txheeb xyuas ntau yam khoom uas ua tau raws li cov khoom zoo thiab qhov tsis zoo thiab siv cov kev cai: compressive zog: ntsuas 10 qauv nrog sy-30 hydraulic siab kuaj tshuab. Qhia luv luv piav qhia txog lub ntsiab sab hauv thiab kev ua haujlwm ntawm lub phaj ntauwd, thiab tus kheej kheej tuaj yeem poob ywj pheej ntawm kab rov tav steel phaj ntawm qhov siab ntawm 6m lossis 10m,
The purpose of sterilization and algae killing cleaning is to kill microorganisms in the system. It is qualified if the sphere is not broken. Thermal shock resistance: it is qualified if the activated alumina with a diameter of 10mm is quenched at 850 degree 19 degree (water) without cracking, peeled off and separated from the biological slime attached to the equipment surface, or cooled in an electric furnace for five times without cracking. Chemical stability: the test method of hydrofluoric acid etching resistance is to clean and dry the porcelain particles after discharging the cleaning water（ Ф 1.5 0.5mm) 10g (accurately weighed to 0.0001g), add bactericide and algicide into the system for cleaning and put it into a plastic cup. When the turbidity of the system is balanced, stop cleaning and inject about 250ml of 0.2 percent hydrofluoric acid,
Lub hom phiaj ntawm activated alumina tu yog kom yaj cov nplai thiab oxide nyob rau hauv lub kaw lus nyob rau hauv dej nrog tu tus neeg saib xyuas rau ntxuav. Tom qab sawv ntsug rau 24 teev, muab cov tshuaj ntxuav tes tso rau hauv nruab nrab cua txias system, thiab tom qab ntawd ntxuav, qhuav thiab hnyav.
