txheej txheem ntawm lub cev rov tsim dua tshiab
Cov txheej txheem no tsim nyog rau kev lim cov xov xwm uas muaj qhov tsis zoo me me thiab qhov teeb meem ntawm qhov teeb meem hauv titanium lim cores. Piv txwv xws li ozone disinfection filtration thiab air filtration.
1. Rov qab ntxuav: Siv cov dej ntshiab (deionized dej) rov qab ntxuav hauv qhov kev taw qhia rov qab rau 15 feeb, nrog lub zog rov qab los ntawm qis dua 0.4 MPa, los yog siv cov cua huv (steam) rov qab ntxuav, nrog lub backwash siab tsawg dua tshaj 0.4 MPa.
2.Ultrasonic ntxuav:Muab cov pas nrig titanium tso rau hauv lub tank tu ultrasonic, ntxuav rau 60 feeb, ces tshem tawm thiab yaug nrog dej deionized los yog dej distilled rau 15 feeb. Tom qab ziab thiab sterilization, nws yog npaj rau siv.
txheej txheem kev kho tshuaj
Txheej txheem kev kho tshuaj:
Cov txheej txheem no tsim nyog rau kev thaiv hnyav hauv titanium lim cores thiab lim tawm nrog cov txheej txheem nyuaj (xws li decarbonization filtration, pom nrog cov protein-raws li xov xwm, lossis cov xov xwm viscous heev).
Alkaline Ntxuav Cov Txheej Txheem: Rau siv tshiab lossis lub sijhawm kaw ntev, muab cov titanium lim cores hauv 1% NaOH tshuaj ntsuam dej cawv rau 30 feeb. Ua ntej immersion, moisten nrog dej zoo tib yam thiab ces raus rau hauv cov tshuaj alkaline. Tom qab immersion, yaug ob sab hauv thiab sab nraud nrog dej deionized tsawg kawg ob zaug, nrog rau txhua qhov yaug tsis pub tsawg tshaj 30 feeb thiab dej siab ntawm 0.2-0.3 MPa. Thaum yaug, muab cov lim dej tso rau hauv cov dej zoo li qub kom txog thaum tsis pom cov khoom ntab (teeb tshuaj xyuas), thiab sim ntsuas pH nruab nrab.
acid ntxuav txheej txheem
1. Kev Npaj Cov Tshuaj Ntxuav:
Potassium (los yog Sodium) dichromate 5% (anhydrous)
Haus dej 1000 g
Concentrated sulfuric acid (industrial-qib) ntxiv ua 2000ml
2. Txoj Kev Npaj:
Noj cov poov tshuaj (los yog sodium) dichromate crystals los yog hmoov zoo, yaj nyob rau hauv dej kub ntawm 60-80 degrees Celsius, thiab maj mam ntxiv concentrated sulfuric acid (94%-96%) kom txog thaum lub ntim yuav tsum tau mus txog. Nws raug nquahu kom ntxiv cov kua qaub maj mam thaum pib, nplawm tsis tu ncua thaum ntxiv. Tom qab ncav cuag 1200ml, cov poov tshuaj (los yog sodium) dichromate yuav tsum tau yaj tag. Thaum xub thawj, cov xim hloov ntawm xim av-liab mus rau ib qho tsaus liab; ntawm qhov no, qhov sib ntxiv ceev tuaj yeem nce me ntsis kom txog thaum ua tiav. Yog tias qee cov khoom siv tsis tau raug tshem tawm tom qab ntxiv tag nrho cov kua qaub, rov ua kom yaj nws, tom qab ntawd cia nws txias, thiab khaws cia rau hauv lub thawv ntim khoom siv tom qab siv.
ntxuav cov kauj ruam
Tshem tawm cov ntsiab lus lim.
Yaug cov phab ntsa sab hauv thiab sab nrauv nrog kev txhaj tshuaj-qib dej los yog lim dej distilled li ntawm 3 feeb ntawm qhov kub ntawm ib ncig ntawm 60 degree.
Siv cov cua compressed (ceeb toom: xyuas kom tsis muaj roj pos huab sib xyaw hauv huab cua) kom tshuab ziab thiab ntxuav cov tee dej.
Muab cov khoom tso rau hauv cov tshuaj ntxuav (ntawm qhov siab ntawm 2.5%-3%) thiab tsau rau li 15 feeb, ces tshem tawm.
Yaug rau sab hauv thiab sab nraud kwv yees li peb zaug nrog dej deionized lossis dej distilled ntawm qhov siab ntawm 0.3-0.35 MPa, ntawm qhov kub qis dua 80 degree , lossis ntawm chav tsev kub.
Siv cov dej kub kom tshuab-qhuav cov dej seem ntawm cov khoom ncaj qha mus rau hauv lub tshuab kom tsis muaj menyuam kom tsis muaj menyuam li 40 feeb.
Yaug nrog me me ntawm cov dej txhaj tshuaj thiab tswj qhov kub thiab txias ntawm 112 degree lossis siab dua rau tsawg kawg 1 teev.
Muab tso rau hauv lub thawv kaw kom tsis muaj menyuam rau kev tiv thaiv.
