Q1: Yuav ua li cas kom huv thiab tswj xyuas lub lim roj 304 stainless hlau mesh kom zoo?
A1: (1) Txoj kev ntxuav: Siv lub tshuab ntxuav ultrasonic (zaus 40kHz, kub ≤ 60 ° C) lossis rov qab ntxuav (siab ≤ 0.3MPa) kom tshem tawm cov khoom tsis huv.
(2) Cov kev cai ziab: Tom qab ntxuav, siv cua tsis muaj roj los tshuab kom qhuav (kom tsis txhob muaj oxidation los ntawm cov dej seem).
(3) Kev Txwv: Tsis txhob muab cov kua qaub (xws li hydrochloric acid) lossis cov hauv paus muaj zog (xws li sodium hydroxide) tsau rau hauv kom tsis txhob ua rau cov txheej passivation ntawm qhov chaw puas tsuaj.
Q2: Cov lim dej no puas haum rau cov roj viscosity siab xws li roj iav thiab asphalt?
A2: Kev Siv Tau: Txhawb cov kua dej lim nrog cov viscosity dynamic ≤ 680 cSt (centics) (xws li ISO VG 680 iav roj), vim tias cov qauv mesh ntau txheej tuaj yeem tiv taus qhov sib txawv ntawm siab ≤ 0.15 MPa.
Qhov txwv kub: Xyuas kom tseeb tias qhov kub ntawm roj yog ≤ 300 ° C (qhov siab tshaj plaws luv luv ntawm 400 ° C) kom tsis txhob muaj kev qaug zog ntawm cov hlau los ntawm qhov kub siab.
Cov xwm txheej xwm txheej: Nws tau siv dav hauv kev lim roj hydraulic thiab asphalt conveying systems ntawm cov tshuab mining.
Q3: Puas yog qhov tseeb ntawm lub lim dej sib xws nrog cov nyhuv lim tiag tiag?
A3: Kev txhais qhov tseeb: Qhov tseeb nominal yog raws li qhov kev xeem beta (ISO 16889), piv txwv li, β ₅ = 200 qhia txog kev cuam tshuam ntawm ≥ 99.5% rau cov khoom me me ≥ 5 microns.
Cov yam cuam tshuam: Qhov ua tau zoo tiag tiag yuav muaj qhov sib txawv ntawm ± 5% vim yog qhov huv ntawm cov kua dej, qhov ntws (pom zoo 1-3 m/s), thiab qhov kub thiab txias hloov pauv.
Txoj kev txheeb xyuas: Kev ntsuas thiab calibration ntawm qhov chaw tuaj yeem ua tiav los ntawm kev siv lub tshuab suav cov khoom me me (ua raws li tus qauv ISO 4406).
1. Kev tsim tshwj xeeb tuaj yeem ua tiav thaj chaw lim dej zoo ntawm 100%;
2. Txhua yam khoom siv txoj kev sib xyaw ua ke, uas daws tau ntau yam teeb meem uas tau muaj thaum pib siv thiab ua kom muaj kev nyab xeeb;
3. Tus qauv tsim siv lub thav duab hlau, uas tuaj yeem rov siv dua thiab hloov pauv;
4. Qhov ceev ntawm cov khoom siv lim qhia tau tias muaj cov qauv nce ntxiv, ua tiav kev ua haujlwm siab, tsis tshua muaj kev tiv thaiv, thiab muaj peev xwm plua plav loj;

Yaj cov potassium dichromate lossis cov siv lead ua hauv dej kom txog 60 txog 80 degrees, thiab maj mam ntxiv cov concentrated sulfuric acid nrog qhov concentration ntawm 94% kom txog thaum txaus. Ntxiv maj mam thiab do. Ntxiv txog li 1200 milliliters ntawm potassium sulfate lossis yaj tag nrho, thiab cov tshuaj yuav tshwm sim xim liab tsaus. Lub sijhawm no, tus nqi ntawm kev ntxiv concentrated sulfuric acid tuaj yeem ua kom nrawm dua kom txog thaum nws raug ntxiv tag nrho. Yog tias tseem muaj cov siv lead ua tsis tau yaj tom qab ntxiv concentrated sulfuric acid, lawv tuaj yeem ua kom sov kom txog thaum yaj. Lub luag haujlwm ntawm kev ntxuav cov tshuaj yog tshem tawm cov pa phem dav dav, roj, thiab cov khoom hlau tsis huv ntawm phab ntsa ntawm stainless hlau lim cartridge, thiab nws tuaj yeem tua cov kab mob thiab cov kab mob me me uas loj hlob ntawm lub lim cartridge thiab ua puas rau qhov chaw kub. Yog tias cov khoom lim tau ntxuav alkaline ua ntej, cov tshuaj alkaline yuav tsum tau ntxuav ua ntej, txwv tsis pub cov roj acids yuav precipitate thiab ua rau cov khoom lim puas tsuaj.
