Abrasive hmoov yog cov khoom siv nrov heev hauv kev lag luam siv los ntxuav cov hlau los ntawm xeb. Muaj ntau ntau yam ntawm nws, sib txawv ntawm cov khoom thiab tus nqi. Cov hmoov av abrasive kuj tseem siv tau ntau yam.

Khoom zoo

Tam sim no, kev lag luam tsim tsuas yog ob lub ntsiab ntawm cov hmoov abrasive: tooj liab slag thiab npib tsib xee slag. Lawv pib siv rau hauv kev tsim khoom tsis ntev dhau los. Yav dhau los, zoo tib yam quartz xuab zeb tau siv los hloov. Thaum ntxuav qhov chaw kawg, cov plua plav zoo heev hauv huab cua, ua rau txhua yam nyob ib puag ncig. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum ua kom muaj kev ua haujlwm nyuaj thiab raug nqi ntau rau kev ntxuav cov khoom ua tiav. Tsis tas li ntawd, cov khoom me me ntawm quartz ya saum huab cua poob rau hauv lub ntsws ntawm cov neeg ua haujlwm. Yog li ntawd, lawv tau tsim muaj kab mob ua haujlwm ntev - silicosis. Hmoov tsis zoo, nyob rau hauv peb lub teb chaws, pheej yig quartz xuab zeb tseem siv los ntxuav qhov chaw. Hauv Tebchaws Europe, nws yog categorically siv rau lub hom phiaj notxwv tsis pub.

Ntau yam

Feem ntau, tooj liab slag yog siv hauv kev tsim khoom. Qhov no yog cov khoom siv pheej yig uas tso cai rau kev tu kom zoo. Nickel slag txawv ntawm nws nyob rau hauv ntau dua particle zog. Tsis tas li hauv kev lag luam, xws li hom abrasive li pob zeb diamond hmoov yog qee zaum siv. Txawm li cas los xij, nws kim heev, thiab yog li nws tsuas yog siv rau kev tsim cov cuab yeej sib tsoo, pastes thiab ncua kev kawm.

Yuav ua li cas

Kev tsim cov hmoov abrasive tsis yog kev siv tshuab nyuaj. Cooper slag los ntawm granulated tooj liab-smelting slags. Lawv raug txo mus rau lub xeev nplua-grained los ntawm ceev ceev txias nrog dej. Lub resulting hmoov rau ntxuav los ntawm ntau yam pliaj impurities yog muab tso rau ib tug tshwj xeeb inclined grate nrog me me hlwb. Yog li ntawd, me me ntawm cooper slag sawv los. Cov loj (limestone, refractory khoom, khib nyiab) nyob rau saum.

Nickel slag yog tsim los siv tib lub tshuab. Qhov txawv tsuas yog qhov no, nickel slags yog siv los ua khoom noj.

Ntse

Cov khoom tseem ceeb uas txiav txim siab zoo ntawm cov khoom xws li cov hmoov abrasive yog:

1. Degree ntawm hygroscopicity. Qhov me me, qhov khoom zoo dua. Cov hmoov qhuav tuaj yeem siv rau hauv cov txheej txheem tsim khoom tam sim ntawd, tsis tas siv sijhawm thiab nyiaj txiag rau ziab.

2. Flowability. Qhov noqhov taw qhia rau abrasive hmoov yuav tsum siab npaum li qhov ua tau. Cov ntaub ntawv pub dawb heev yooj yim dhau los ntawm lub nozzle ntawm cov cuab yeej tsim los ntxuav qhov chaw yam tsis muaj clogging. Vim li ntawd, cov cuab yeej siv tsis ua haujlwm ntev dua.
3. Ratio of fractions. Tsuas yog cov khoom ntawd raug suav tias yog cov khoom zoo, uas suav nrog cov khoom sib txawv (ntawm 0.5 txog 3 hli).

Raws li qib kev phom sij rau tib neeg lub cev, cov hmoov abrasive raug xa mus rau pawg plaub. Qhov no txhais tau tias koj tuaj yeem ua haujlwm nrog nws yam tsis muaj kev ntshai ua rau koj noj qab haus huv. Kev sib piv: cov ntaub ntawv xws li cov khoom seem hlau thiab hmoov seem thaum sib tsoo ntawm cov hlau yog muab rau tib chav kawm plaub yam txaus ntshai.

Scope of application

Yog li, feem ntau cov hmoov abrasive yog siv los ntxuav qhov chaw ntawm cov khoom hlau los ntawm xeb. Tsis tas li ntawd, nws yog siv los tshem tawm cov xim thiab plaster residue ntawm pob zeb thiab cib. Abrasive hmoov kuj tseem siv tau los tshem tawm qhov chaw puas lossis thawed thaum kho ua haujlwm.

Kev kho deg nrog cov khoom siv no tuaj yeem ua tiav ob qho tib si los ntawm kev sib tsoo abrasive, thiab los ntawm hydro- lossis nplaim-abrasive.

Sib piv ntawm cooper slag thiab quartz xuab zeb

Tau kawg, cov hmoov txhuam hniav niaj hnub no kim dua li quartz xuab zeb. Txawm li cas los xij, nws qhov kev ua tau zoo dua qub. Kom meej meej, hauv qab no peb nthuav qhia rau koj mloog ib lub rooj sib piv obcov ntaub ntawv.

Abrasive hmoov: noj

Cov khoom uas ua rau tooj liab slag thiab npib tsib xee slag muaj cov npoo ntse heev. Yog li ntawd, kev kho deg nrog lawv tuaj yeem ua tau zoo heev. Nyob rau tib lub sijhawm, tsis zoo li quartz xuab zeb, abrasive hmoov xyaum tsis tsim cov plua plav. Thiab yog li ntawd, cov khoom ua tiav tsis tas yuav tsum tau ntxuav, siv nyiaj ntxiv rau qhov no.

Plua plav thaum lub sij hawm ntxuav nrog quartz xuab zeb yog tsim vim nws cov khoom muaj zog heev. Qhov no xyaum tsis tshwm sim nrog abrasive hmoov. Yog li ntawd, lawv tuaj yeem siv los ntxuav ob zaug, thiab qee zaum txawm peb zaug. Ntawm cov hoob kawm, qhov no ho txo lawv noj. Yog li ntawd, nws yog qhov zoo los siv tooj liab slag thiab npib tsib xee slag, txawm tias lawv raug nqi ntau dua li xuab zeb. Kev noj cov hmoov abrasive ib 1 m2 tsuas yog li 30 kg. Kev sib piv: xuab zeb rau tib cheeb tsam yuav tsum siv li 100 kg.

Abrasive hmoov: GOST

Raws li qhov cuam tshuam rau tib neegcooper slag thiab npib tsib xee slag, raws li twb tau hais lawm, koom rau pawg plaub (raws li GOST 12.1.007). Hauv kev tsim cov hmoov abrasive, cov qauv ntawm GOST 17.2.3.01-86 hais txog qhov siab tshaj plaws emissions yuav tsum raug soj ntsuam. Kev tswj hwm lub xeev tus qauv thiab hom kev tiv thaiv tus kheej ntawm cov neeg ua haujlwm thaum ua haujlwm nrog tooj liab slag thiab npib tsib xee slag (GOST 12.4.034). Qhov siab tshaj plaws cov ntsiab lus ntawm radionuclides nyob rau hauv cov hmoov abrasive yog tswj los ntawm GOST 30108. Qhov tseeb, cov khoom no feem ntau yog tsim raws li TU 1789-001-34557754-99.

siv tsev

Qee cov kws ua haujlwm xav paub qhov twg cov hmoov txhuam tuaj yeem siv tau. Cooper slag thiab npib tsib xee slag hauv tsev tsis tuaj yeem siv tau. Lawv tau siv tam sim ntawd hauv qhov tseem ceeb los ntxuav qhov chaw loj. Hauv tsev, tsuas yog siv cov hmoov pob zeb diamond xwb. Lawv zoo haum rau kev ua pastes npaj rau polishing ntau yam ntawm complex hlau khoom.

Tsis tas li, cov hmoov pob zeb diamond feem ntau yog siv rau kev tsim khoom ntawm cov cuab yeej ua tiav. Nyob rau hauv rooj plaub no, ib qho tshwj xeeb abrasive pob zeb feem ntau yog siv los ua lub hauv paus. Tom qab degreasing, txheej txheej ua haujlwm ntawm cov hauv qab no yog siv rau nws (% los ntawm qhov hnyav):

• pob zeb diamond hmoov - 2-4;
• tooj liab oxide hmoov - 25-35;
• phosphoric acid - so.

Tus nqi

Tus nqi ntawm npib tsib xee slag thiab tooj liab slag yog hais txog tib yam. Cov hmoov no raug nqi txog 3000-3500 rubles ib tuj. Tus nqi ntawm quartz xuab zeb nyob ntawm 800-900 rubles ib tuj. Pob zeb diamond hmoov yog, ntawm chav kawm, kim heev. Lawv muag nws tsis nyob rau hauv tons thiab tsis txawm nyob rau hauv kilograms, tab sis nyob rau hauv grams. Nws tus nqi yog 35-70 rubles ib gram.

Raws li koj tuaj yeem pom, cov hmoov abrasive yog cov khoom siv tau zoo thiab nrhiav tau. Nws ntau hom tuaj yeem siv rau hauv kev lag luam thiab hauv tsev. Nws tsis ua rau muaj kev phom sij rau kev noj qab haus huv, thaum nws cov yam ntxwv ua haujlwm tsuas yog qhov zoo tshaj plaws.
