Tawg nyob rau hauv ib tug abrasive lub voj voog (a), nti txiav ntug (b) thiab "cheb tsev", nyob rau hauv lub voj voog uas nws tsis pom zoo
Koj puas tau txiav tawm cov steel ces kaum ntawm 35 x35mm rau lub tsev cog khoom thav duab lossis cov kav dej rau hauv tsev neeg? Yog tias muaj, tom qab ntawd xaiv nruab nrab ntawm cov hlau rho tawm, ib lub disk pom, lossis cov kev txiav nyom ntawm lub voj voog, tej zaum nyiam tau tshaj tawm cov feem ntau yog qhov nrawm dua thiab yooj yim.
Abrasive txiav cov voj voog uas xws li Austrian Terolit, Minch thiab Sisa, Yugoslav Suma, Qhov twg Aoot "Mosshlifminstrutrent" (OJSC "LUZHSCY Abrasive cog", nroj "Montajabrastrument" (PM).
Abrasive (delates. Acbrasio-Scraping) Lub log txiav tau npaj rau ntau yam khoom lag luam, thaiv hlau, pob zeb, ces yog cov ntawv sau cia), thiab cib , slate, ceramics, phab ntsa ntub, zoo li marble, granite, pob zeb thiab pob zeb thiab cov khoom hauv cov khoom me me. Peb xav tau tsuas yog lub tshuab txiav txiav lossis kev sib tsoo ntawm lub cev, hu ua "Bulgarian".
Nws yog ib qho tsim nyog los ceeb toom tias ntau tus neeg lag luam uas tsim cov kev txiav cov tshuab ua thiab txiav cov voj voog rau lawv cov hom, tsis yog cov tuam ntxhab.
Qhov ceev ntawm kev sib hloov ntawm lub voj voog yog loj, tsuas yog qhov siab zoo ntawm nws cov khoom tsim tau tuaj yeem lav tau kev nyab xeeb. Cov voj voog yog ua rau cov npe ntawm cov khoom lag luam thiab cov kev pabcuam uas yauv ua daim ntawv pov thawj yuav tsum tau ua ke. Yog li, qhov zoo ntawm cov khoom ntawm Aoot "MoskslifryThu" (lawv yuav tau sib tham) paub los ntawm cov ntawv pov thawj kev lees paub los ntawm lub xeev cov txheej txheem ntawm Lavxias Federation.
Ntau txoj cai rau kev xaiv qhov kev txiav abrasive txiav abrasive
Kuaj xyuas tias lub voj voog tsis yog deformed, thiab tsis muaj cov kab nrib pleb thiab tej daim ntawm cov nplaim dej.Nws yog ntshaw tias tus nqi tshwj xeeb tshaj plaws ntawm kev tig ceev ntawm lub voj voog yuav tsis tsawg tshaj li kev siv ceev ntawm bulgarian siv.
Nco ntsoov tias kev txiav tau tsuas yog 2/3 ntawm txoj kab uas hla ntawm txoj kev lim hulcast.
Lub zog ntxiv dag zog tsis yog ib txwm muab rau los ntawm kev tsim qauv ntawm abrasive lub voj voog, thiab nws tuaj yeem raug txiav txim los ntawm daim ntawv lo. Yog li, hauv tsev tuam ntxhab, tsab ntawv "bu" txhais tau tias "bakelite pawg nrog lub caij hardening". Yog tias "y" yog tsis tuaj, tsis muaj xws li lub voj voog uas yog "Bulgarian" tsis pom zoo.
Tus me dua qhov siab ntawm lub voj voog, qhov yooj yim nws yog txiav thiab tsis txhob nkim, tab sis kuj hnav ntau dua. Nrog qhov siab tsawg kawg ntawm lub voj voog (5 qhov ntau thiab tsawg ntawm cov lus), ib qho kev phem me me yog siv thiab, yog li ntawd, kev ua tau zoo tsawg.
Cov abrasive txiav, feem ntau yog siv nyob rau hauv tsev neeg, yog daim disk nyias nrog qhov siab ntawm 1 lossis 32mm, uas feem ntau framed los ntawm hlau Calibration lub tes tsho. Piv txwv li, nrog txiav "grinder" vim muaj qhov tseem ceeb ntawm lub zog, txoj kab uas hla ntawm lub voj voog tsis tshaj 230mm. Koj tuaj yeem ua tau raws lub voj voog txiav nrog txoj kab uas hla ntawm 100 thiab txawm tias 80mm nrog ib qho hluav taws xob sib xyaw, mounted ntawm lub qhov rooj hluav taws xob hauv tsev nrog lub mandrel.
Lub voj voog abrasive txiav cov hlau faib ntawm cov hlau nplaum ntawm cov khoom tawv tawv tawv (abrasive), zoo li thaj av uas muaj abrental. Lawv tau sib xyaw ua ntej, thiab tom qab ntawd nws compressed nrog ib lub tsev elastic sib xyaw loj, lub tsev loj ntawm uas yog bakelite (yas) lossis vulcanite (roj hmab). Lub ntsej muag ntse ntawm cov prorasive los ntawm cov npoo ntawm lub ligament thiab, mob rau hlau, txiav mus rau hauv cov zoo tshaj plaws chips. Hauv kev tsim cov sib tov ntawm cov pob ntawm cov bundles, cov abrasive thiab fiber tau muab tso rau hauv daim ntawv, nws yog cog thiab ua tiav thermally. Combs nrog bakelite pawg muaj ntau dua siv rau ntxhib txiav ntawm hlau thiab lub tsev tsis yog xim hlau cov ntaub ntawv. Cov voj voog nrog cov roj hmab-tsawg dua kev ua tau zoo thiab yog tsim rau kev txiav hlau, titanium alloys thiab tau txais smoother npoo ntawm kev txiav (tsis siv nyob rau hauv lub neej txhua hnub).
Kev ua tau zoo ntawm cov kev sib ntaus sib tua sib txawv yog nyob ntawm qhov loj me thiab tawv tawv ntawm cov hais thiab cov abrasive nws tus kheej, dua cov hlau tuaj yeem txiav. Abrasive gradeiness, lossis particle loj, tuaj yeem yog los ntawm0.1 txog 2 hli (100-2000 microns). Nws ib txwm qhia cov cim hauv cov chav sib xyaw, thiab hauv Lavxias thiab lwm lub tebchaws sib txawv.
Tom qab sim cov voj voog rau ntawm cov tshuab zog thiab impassableness ntawm daim ntawv lo ntawm lawv, ntsuab (rau cov ntaub ntawv tsis yog xim hlau) lossis xiav (qauv). Cov ntaub ntawv ntxiv tau tshaj tawm muaj.
Hauv cov khoom lag luam hauv tsev, cov txhuv sib thooj siab tshaj 50 MKM yog txhais tau li 0.1 sab ntawm cov sab cib uas cov abrasive hais yog sifted thaum sorting loj. Piv txwv li, cov gradeiness 32 qhia pom tias muaj cov khoom ntawm lub ntsiab loj ntawm 320mkm thiab ib qho me me ntawm cov nplej ntawm lwm qhov ntau thiab tsawg.
Kev lom zem ntawm los ntawm 5 txog 63mkm yog txhais los ntawm qhov ntau tshaj plaws qhov loj me (m). Qhov tseeb, M28 qhia tau qhov ntau tshaj plaws hauv 28 μm. Raws li cov qauv thoob ntiaj teb ISO, cov Abrasive abrasive yog muab rau cov khoom sib txawv uas tsis cuam tshuam txog cov khoom sib txawv, cov kab (F) thiab cov tawv nqaij sib tsoo (P). Yog li, F54 qhia tau tias qhov nruab nrab particle loj ntawm cov abrasive hais siv nyob rau hauv kev tsim khoom yog 300 mkm, thiab cov tawv nqaij abrasive nrog tib lub perr me me yuav qhia los ntawm p50. Raws li cov qauv Lavxias, thiab rau kev txiav abrasive lub voj voog, thiab kev sib dhos nrog lub ntsiab lus tseem ceeb ntawm 3220mkm thiab ib qho kev tsim tawm 32 (saib cov lus) feem ntau sib haum rau cov tiab sib tsoo.
