Hauv kev lag luam thauj khoom loj xws li kev khawb av, metallurgy, thiab kev tsim hluav taws xob, silo blockage thiab chute hnav yog ob qho teeb meem ntev uas cuam tshuam rau kev tsim khoom, ua rau muaj nqi siab thiab kev nyab xeeb ntawm tus kheej. Cov ntaub ntawv hlau ib txwm muaj tau ntsib teeb meem ntev xws li kev nplaum, xeb, hnav sai, thiab suab nrov. Ultra-high molecular weight polyethylene (UHMWPE) cov ntawv, nrog lawv qhov kev tiv thaiv kev hnav zoo dua, kev tiv thaiv kev cuam tshuam, kev ua kom nws tus kheej lubricating thiab cov khoom tsis nplaum, maj mam tshwm sim ua cov txheej txheem txheem rau cov khoom siv mining niaj hnub, tiv thaiv kev ruaj khov thiab kev ua haujlwm ntawm cov kab ntau lawm.
Kev Tiv Thaiv Silo Blockage thiab Arching: Hais Goodbye rau "Intestinal Obstruction"
Cov khoom ntub dej (xws li cov hlau, cov thee ntub dej, av nplaum), tshwj xeeb tshaj yog nyob rau hauv cov khoom conical, yooj yim lo rau ntawm phab ntsa silo, ua rau muaj qhov thiab arches, ua rau cov dej tawm tsis sib npaug thiab yuav tsum tau ntxuav tes, uas tsis yog tsuas yog tsis ua haujlwm zoo xwb tab sis kuj txaus ntshai heev.
Yog li ntawd, kev tso cov ntawv UHMWPE ua cov ntaub thaiv rau ntawm phab ntsa sab hauv ntawm silos, tshwj xeeb tshaj yog nyob rau hauv thaj chaw conical thiab qhov chaw tso tawm, daws qhov teeb meem no zoo kawg nkaus.
Hauv lub silo concentrate iron ore hauv Johannesburg, South Africa, peb cov ntawv UHMWPE tuab 20 hli tau raug ntsia tag nrho. Tom qab kev txhim kho, kev nplaum tau txo qis 90%, ua tiav cov khoom ntws los ntawm lub ntiajteb txawj nqus. PebDaim ntawv UHMWPEs tau txuag lub tuam txhab txog li $ 2 lab txhua xyoo hauv kev ntxuav silo thiab cov nqi poob peev xwm.
Kev Tiv Thaiv Kev Hnav thiab Kev Txo Suab Nrov: Tsim "Kev Mus Los Ceev Ceev Uas Ntshai"
Cov hlau, thee, thiab cov slag poob sai heev hauv cov chutes, ua rau muaj kev cuam tshuam loj heev rau cov ntsiab lus hauv qab. Cov hlau chute liners hnav sai, tsim suab nrov heev, thiab yuav tsum tau hloov pauv ntau zaus.
Yog li ntawd, peb tau teeb tsa cov ntawv UHMWPE ua cov ntaub thaiv uas tiv taus kev hnav ntawm lub phaj hauv qab chute, cov phaj sab, thiab cov khoom siv cuam tshuam.
Peb tau teeb tsa cov ntaub thaiv ntawm qhov chaw hloov pauv ntawm lub qhov av thee hauv Mexico City, hloov cov phaj hlau uas tiv taus hnav 16 hli tuab qub nrog cov ntawv UHMWPE tuab 30 hli. Tom qab kev hloov kho tshiab, lub neej ntawm cov ntaub thaiv tau nce ntxiv los ntawm 6 lub hlis ib txwm mus rau ntau tshaj 5 xyoos. Tib lub sijhawm, suab nrov ua haujlwm tau txo qis los ntawm 120 decibels mus rau qis dua 80 decibels, txhim kho qhov chaw ua haujlwm zoo heev. Tus nqi tag nrho ntawm ib qho kev hloov pauv qis dua li cov phaj hlau, ua rau lub neej ua haujlwm ntev dua thiab txo qhov zaus hloov pauv. Tib lub sijhawm, cov suab nrov txo qis txo cov nqi tswj kev noj qab haus huv hauv chaw ua haujlwm.
Ua ib qho tseem ceeb hauv silos thiab chutes, UHMWPE daim ntawv, vim lawv lub neej ua haujlwm ntev, txo cov nqi yuav khoom ntawm cov chaw tsim khoom, txo cov neeg ua haujlwm thiab cov nqi txij nkawm, thiab txo cov kev poob ntau lawm vim lub sijhawm tsis ua haujlwm los ntawm kev txij nkawm.
Cov ntawv UHMWPE yog cov uas tsis yooj yim hnav, tsis yooj yim cuam tshuam, nws tus kheej lubricating, thiab tsis muaj qhov lo rau, tiv thaiv cov khoom thaiv, txo qhov tsis kam ntawm kev ntws, thiab ua kom muaj kev nyab xeeb thiab kev phooj ywg ib puag ncig, yog li txhim kho kev ua haujlwm ntau lawm.
DUA LIDaim ntawv UHMWPEs yog tsim tshwj xeeb rau cov chaw ua haujlwm hnyav. Peb muab tsis yog cov ntawv xwb, tab sis ib txheej ntawm cov kev daws teeb meem tiav, kev siv tshuaj tiv thaiv kev hnav.
Qhov kev tiv taus hnyav thiab kev cuam tshuam ntawm cov khoom siv UHMWPE ua rau nws yooj yim tiv taus kev cuam tshuam ntawm xuab zeb thiab pob zeb. Lub caij no, nws txoj kev tiv thaiv corrosion ua rau nws tsim nyog rau ntau yam khoom siv minerals, suav nrog acidic, alkaline, thiab saline media. Nws lub suab qis thiab tsis muaj tshuaj lom, tsis muaj ntxhiab ua rau nws muaj kev nyab xeeb dua thiab zoo rau ib puag ncig.
Peb cov ntawv UHMWPE tuab ntawm 8mm txog 260mm, ua tau raws li qhov xav tau ntawm cov neeg siv khoom nrog ntau yam kev hnav hnyav. Peb lub chaw ua haujlwm CNC tuaj yeem muab cov tshuab ua haujlwm tsis yog tus qauv, muab cov phaj txheej tiav rau cov silos conical thiab chute lub luj tshib phaj kom ua tiav kev teeb tsa ntawm UHMWPE daim ntawv. Peb kuj muab cov khoom siv ruaj ntseg xws li countersunk bolts thiab cov khoom siv ceramic kom ntseeg tau tias muaj kev teeb tsa ruaj ntseg.
