Hloov mus rau Tsis yog-Kev them nyiaj yug hlau: Vim li cas FRP Bolts Hloov Hlau Hauv Ib puag ncig nyuaj
Tau ntau xyoo lawm, yog tias koj taug kev hauv av hauv av thiab nug dab tsi tuav lub ru tsev, cov lus teb yeej ib txwm zoo ib yam: steel. Steel rebar, steel split poob lawm, steel cable strands. Thiab rau feem ntau, nws ua haujlwm.
Tab sis yog tias koj puas tau tswj xyuas qhov ntub dej, corrosive coal seam los yog saib ntau - lab- daus las thee shearer grind kom nres vim nws clipped ib txoj hlua steel, koj paub tias steel muaj qhov muag tsis pom kev.
Tias yog vim li cas, nyob rau ob peb xyoos dhau los, kuv tau pom ntau thiab ntau tus thawj tswj xyuas qhov haujlwm ntsiag to ua kev hloov mus rau FRP (Fiberglass Reinforced Polymer) Bolts. Lawv tsis yog "cov qauv niaj hnub" xwb-lawv yog qhov kho kom haum rau qhov tshwj xeeb, kim qhov chaw mob taub hau. Wb tham txog vim li cas.
Cia peb ua siab ncaj txog dej hauv av. Nws tsis tshua muaj dej huv xwb; Nws feem ntau yog acidic, tag nrho ntawm sulphates, thiab ua phem rau cov hlau.
Kuv tau taug kev los ntawm kev thauj mus los qhov twg tus qauv steel bolts ntsia NW nyuam qhuav peb xyoos ua ntej tau ntsuas mus rau ib nrab ntawm lawv cov tuab los ntawm corrosion. Thaum qhov ntawd tshwm sim, koj qhov kev nyab xeeb kev nyab xeeb poob ntawm pob tsuas, thiab tam sim ntawd koj tab tom siv nyiaj rau cov nqi re-bolting tej yaam num.
FRP tsuas yog tsis quav ntsej txog acid. Vim tias nws yog ib qho kev sib xyaw ntawm siab - lub zog iav fibers kaw hauv cov tawv tawv matrix, nws yuav tsis xeb. Lub sijhawm. Yog tias koj qhov nyiaj txiag Opex tau los ntshav tas li vim dej hauv av zom los ntawm koj cov nyiaj txhawb nqa steel, hloov mus rau FRP tsis yog lub tswv yim radical- nws tsuas yog lej lej xwb.
2. Qhov "Cutability" Factor (Txuag Koj Lub Tshuab)
Ntawm no yog qhov teeb meem loj thib ob FRP daws, tshwj xeeb tshaj yog nyob rau hauv longwall lossis retreat mining:tus coal shearer.
Thaum ib tus neeg ua haujlwm tsis tu ncua lossis tus kws txiav plaub hau yuav tsum txiav txoj cai los ntawm cov pob zeb thaum lub sijhawm rho tawm, ntsib cov hlau yog npau suav phem. Cov tungsten carbide txiav picks ntaus cov hlau, sparks ya, cov hniav tawg, thiab lub nruas tau wrecked.
Kuv tau pom ib qho xwm txheej uas ib qho tsis muaj steel ntsia liaj qhov rooj nres ntau lawm rau kev hloov pauv tag nrho, raug nqi ntau txhiab hauv qhov chaw thiab teev ntawm cov khoom ploj.
FRP hloov qhov kev ua si tag nrho.Thaum tus shearer tsoo FRP ntsia liaj qhov rooj, lub tshuab tsuas yog grinds nws mus rau hauv cov fibers tsis muaj teeb meem. Tsis muaj cov hniav tawg, tsis muaj qhov ci, tsis muaj kev npaj tsis tau. Nws yog lub tshuab- cov khoom siv zoo tsim los rau kev siv tshuab mining niaj hnub.
Nws suab me me thaum koj tab tom saib daim ntawv nthuav dav hauv huab cua -chaw ua haujlwm txias, tab sis tham nrog cov neeg ua haujlwm bolting hauv av.
Hlau yog hnyav. Haunting hnyav bundles ntawm steel rebar tob hauv av, lifting lawv overhead nyob rau hauv ib tug cramped 2.5-meter siab nkag, yuav siv sij hawm ib tug loj tus naj npawb ntawm lub cev.FRP bolts yog kwv yees li ib -lub quarter ntawm qhov hnyav ntawm cov hlau.
Cov ntaub ntawv sib zog txhais tau tias tus neeg ua haujlwm qaug zog tsawg dua, lub sijhawm voj voog nrawm dua thaum lub sijhawm teeb tsa, thiab tsawg dua lub xub pwg nyom thiab nraub qaum. Koj cov neeg ua haujlwm hauv av yuav pom qhov txawv ntawm hnub ib.
4. Qhov tseeb tseeb: Qhov twg hlau tseem yeej
Tam sim no, cia peb tsis ua piv txwv FRP yog cov mos txwv nyiaj uas kho txhua qhov kev sib tw mining. Tus engineer tiag tsis muag cov khoom li ntawd.
Hlau tseem tuav lub zog tsis sib haum xeeb thawj zaug shear thiab feem ntau pheej yig dua rau cov qauv, cov av hauv av qhuav qhov twg corrosion thiab tshuab "cutability" tsis yog lub ntsiab tsav tsheb. Yog hais tias koj nyob rau hauv qhuav, nyuaj- pob zeb tunneling nrog loj zoo li qub loads, siab - qib steel tseem yog koj mus- mus.
Qhov ua kom yuam kev yog paub koj geology. Tsis txhob siv FRP txhua qhov chaw vim nws yog niaj hnub; siv nws qhov twg steel tsis.
FAQ
Q: Cov qauv thoob ntiaj teb dab tsi ua koj tus kheej -drilling bolts ua raws li?
A: Peb lub tshuab SDA (xws li R- xov thiab T- xov) yog tsim los ntawm nruj raws li ISO 10208 thiab ASTM cov qauv. Peb siv siab - lub zog seamless steel tubing kom ntseeg tau tias muaj zog tensile zoo dua thiab muaj zog txaus rau kev thov cov mining thiab tunneling tej yaam num.
Q: Vim li cas SDA bolts ua haujlwm zoo dua li cov pob zeb pob zeb hauv av tawg?
A: Cov bolts ib txwm xav tau ua ntej -drilled qhov uas feem ntau tawg hauv av xoob. Lub SDA system sib txuas cov drilling, grouting, thiab anchoring rau hauv ib qho kev ua haujlwm. Qhov no tshem tawm qhov xav tau ntawm cov kav dej thiab tiv thaiv lub qhov borehole, txuag txog li 50% ntawm lub sijhawm installation.
Q: Koj cov txiv ntseej kheej kheej ua li cas tuav cov pob zeb tsis sib xws?
A: Peb precision-engineered spherical txiv ntseej (dome ceev), thaum ua ke nrog domed daim hlau, tso cai rau 7 mus rau 10 degrees ntawm angular them. Qhov no ua kom ntseeg tau tias lub ntsia liaj qhov rooj tswj xyuas qhov ruaj ntseg, qhov chaw thau khoom faib tawm txawm tias lub ntsej muag lub ntsej muag tsis sib xws lossis tsis sib xws.
Yog tias koj qhov chaw sib ntaus sib tua hauv av hnyav, lossis yog tias koj tab tom khiav lub tshuab hluav taws xob lub ntsej muag uas lub tshuab puas tau noj koj cov txiaj ntsig, nws yog lub sijhawm los saib yav dhau los cov hlau qub.
Ntawm Zhongfu Mining, peb tau siv sijhawm ntau los kho peb cov kab pultrusion kom paub tseeb tias peb FRP bolts muaj lub zog tensile zoo ib yam thiab meej, txhim khu kev qha threading. Peb tsis xav kom koj tsuas yog muag ib lub ntsia liaj qhov rooj rau koj xwb-peb xav kom nws yog cov khoom tsim nyog rau koj cov xwm txheej hauv av.
Koj puas xav paub seb FRP puas haum rau koj qhov mine specs?
Tso [peb pab pawg technical] ib kab. Cia peb saib koj cov dej chemistry thiab mining layout ua ke, tsis muaj muag fluff, tsuas yog engineering daws teeb meem.
