1. Cov khoom tseem ceeb ntawm cov khoom siv hniav cuam tshuam rau kev sib xyaw ua ke
Kev cuam tshuam ntawm cov ntaub ntawv hniav ntawm kev sib xyaw ua ke yog feem ntau cuam tshuam los ntawm plaub lub zog tseem ceeb, uas yog kev sib koom ua ke thiab sib koom ua ke txiav txim siab qhov sib tov kawg.
Hardness thiab hnav tsis kamHardness txiav txim siab lub peev xwm ntawm cov hniav los tiv thaiv deformation thiab hnav thaum sib tsoo nrog cov khoom tawv (xws li gravel, ore). Hnav- cov ntaub ntawv tiv taus tuaj yeem tswj tau qhov zoo li qub thiab qhov loj ntawm cov hniav rau lub sijhawm ntev. Yog hais tias cov hniav yog hnav thiab deformed, lub dov lub vojvoog thiab lub kaum sab xis yuav hloov, ua rau txo cov khoom siv siv zog thiab qhov tshwm sim ntawm "tuag sib tov zones". Piv txwv li, thaum sib xyaw ua vaj tse nrog cov ntsiab lus sib sau siab, qis- hnav cov hniav yuav dhau los ua blunt sai, ua rau tsis sib xws ntawm cov cement muab tshuaj txhuam thiab sib sau ua ke.
Corrosion ResistanceHauv kev sib xyaw ntawm cov khoom siv corrosive (xws li tshuaj slurry, acid{0}} hauv paus av), corrosion kuj ntawm cov khoom siv hniav txiav txim siab seb cov hniav nto tseem du thiab tsis zoo. Corroded hniav yuav muaj qhov ntxhib qhov chaw thiab hauv zos pitting, uas yuav ua rau kom cov adhesion ntawm cov ntaub ntawv, ua rau cov ntaub ntawv caking thiab tsub zuj zuj ntawm cov hniav, thiab rhuav tshem lub dynamic tshuav nyiaj li cas ntawm stirring. Nyob rau hauv cov xwm txheej hnyav, qhov corrosion yuav ua rau thinning ntawm cov hniav, cuam tshuam rau lub zog stirring, thiab txo qhov sib tov sib xyaw.
Nto SmoothnessQhov smoothness ntawm cov hniav nto cuam tshuam qhov kev sib txhuam ntawm cov hniav thiab cov khoom. Lub ntsej muag du tuaj yeem txo qhov adhesion ntawm cov khoom khov (xws li mortar, sludge), txhawb txoj kev zawv zawg thiab hloov pauv ntawm cov ntaub ntawv hauv chav sib xyaw, thiab txhim kho kev sib xyaw ua haujlwm. Ntawm qhov tsis sib xws, lub ntsej muag ntxhib yog ib qho yooj yim rau kev ua raws li cov ntaub ntawv, uas tsis tsuas yog txo qhov ua kom zoo ntawm lub ntim, tab sis kuj ua rau kev sib xyaw ntawm cov khoom tshiab thiab qub, cuam tshuam rau kev ruaj ntseg ntawm cov khoom zoo.
Mechanical Strength thiab ToughnessNtxaib-shaft mixers feem ntau nyob rau hauv siab -load ua hauj lwm tej yam kev mob, thiab cov hniav yuav tsum tau dais tej yam thiab shear quab yuam ntawm cov ntaub ntawv. Cov ntaub ntawv uas muaj zog txhua yam muaj zog thiab toughness tuaj yeem zam cov hniav dabtsi yog khoov, tawg lossis tawg nyob rau hauv siab load, ua kom muaj kev ruaj ntseg ntawm kev sib tw trajectory. Yog tias cov hniav yog nkig thiab yooj yim tawg, nws yuav tsis tsuas cuam tshuam rau kev sib xyaw ua ke, tab sis kuj ua rau muaj kev nyab xeeb rau kev ua haujlwm ntawm cov khoom siv.
2. Cov khoom thib ob ntawm cov khoom siv hniav cuam tshuam rau kev sib xyaw ua ke
Ntxiv nrog rau kev cuam tshuam ncaj qha ntawm cov khoom siv, muaj ob yam thib ob uas tau los ntawm cov ntaub ntawv hniav uas tseem cuam tshuam rau kev sib xyaw:
Hniav Manufacturing PrecisionCov txheej txheem tsim khoom ntawm cov khoom sib txawv yog txawv, uas cuam tshuam rau qhov tseeb ntawm cov hniav loj thiab cov duab. Piv txwv li, hlau alloy yog ib qho yooj yim rau txheej txheem thiab tuaj yeem ua rau hauv cov hniav nrog cov txheej txheem nkhaus, uas tuaj yeem txhim kho cov nyhuv turbulence ntawm cov ntaub ntawv; hnav- cam khwb cia hlau resistant muaj cov txheej txheem tsis zoo, thiab cov hniav zoo nkauj kuj yooj yim, uas txwv qhov kev ua kom zoo ntawm kev sib tw. High- cov hniav precision tuaj yeem ua kom qhov sib xws ntawm kev sib tw, ua rau cov khoom tau txais kev sib tsoo thiab kev cuam tshuam.
Tus nqi tu thiab hloov pauvTxawm hais tias siab - cov ntaub ntawv ua tau zoo (xws li ceramic composites, alloy steel) muaj kev sib xyaw ua haujlwm zoo, lawv cov nqi yuav khoom thiab kev saib xyuas yog siab. Yog tias cov hniav tsis raug hloov raws sij hawm vim kev xav txog tus nqi, qhov hnav thiab deformation ntawm cov hniav yuav ua rau poob ntawm kev sib tov zoo. Ntawm qhov tsis sib xws, xaiv tus nqi- cov ntaub ntawv siv tau zoo sib xws nrog cov xwm txheej ntawm daim ntawv thov tuaj yeem sib npaug ntawm cov txiaj ntsig sib xyaw thiab cov nqi ua haujlwm.
3. Kev xaiv cov txheej txheem ntawm cov khoom siv hniav raws li kev sib xyaw ua ke
Txhawm rau kom ua tiav qhov sib xyaw ua ke ntawm ntxaib -shaft mixers, xaiv cov ntaub ntawv hniav yuav tsum ua raws li cov hauv qab no:
Matching Material yam ntxwvRaws li qhov hardness, corrosivity, viscosity thiab lwm yam ntxwv ntawm cov khoom sib xyaw, xaiv cov khoom siv hniav sib xws. Piv txwv li, xaiv cov hlau alloy los yog ceramic composites rau cov ntaub ntawv nyuaj thiab corrosive; xaiv polymer composites rau siab - cov ntaub ntawv viscosity.
Kev sib xyaw ua haujlwm cov xwm txheejRau kev nruam siab -load ua haujlwm scenarios, ua ntej cov ntaub ntawv nrog siab hnav tsis kam thiab toughness; rau kev sib tshuam thiab qis- cov xwm txheej thauj khoom, cov pa roj carbon zoo tib yam lossis hnav- cov hlau cam tuaj yeem raug xaiv los txo cov nqi.
Xav txog ntev -Lub sij hawm Mixing StabilityTsom ntsoov rau lub neej kev pab cuam ntawm cov hniav, thiab xaiv cov ntaub ntawv uas tuaj yeem tswj qhov kev ua tau zoo rau lub sijhawm ntev, tsis txhob poob ntawm kev sib xyaw ua ke los ntawm cov hniav hnav thiab deformation.
