Coolants: nta thiab xyuas

Yog tsis muaj cov roj nplua nyeem tsis tau ua feem ntau niaj hnub hlau ua. Nyob rau hauv cov ntaub ntawv no, lub nws yog xim hlau ntsiab lawv tus kheej, uas yog siv nyob rau hauv tus txheej txheem yuav tsis tau raws li tej uas yuav tsum tau tsis muaj ib tug tshwj xeeb kev pab cuam nrog. Rau hnub tim, txiav kua (coolant) yog marketed nyob rau hauv ntau tshaj li 600 lub npe. Cov lawv peb yuav nrhiav tau cov nyiaj uas yuav siv nyob rau hauv hwj chim rau lwm rau kev siv nyob rau hauv cov hlau ua, raws li tau zoo raws li kev kho mob, rwb thaiv tsev, formorazdelyayuschie, lom thiab anti-xeb roj. Feem ntau ntawm cov kua uas siv los ntawm kev lag luam thiab kev tsim kho kev lag luam.

Yuav ua li cas yog metalworking kua?

Nyob rau hauv feem ntau lubricants yog nkag tau rau hauv cov ua hauj lwm qhov chaw ntawm lub tsis sib haum xeeb hais nyob rau hauv thiaj li yuav txo tau coj ntawm lub mechanisms. Feem ntau qhov no feature yog complemented los ntawm ib qho kev nce nyob rau hauv efficiency. Tab sis qhov no siv rau cov tsoos ntaub ntawv ntawm no hom, txawm li cas los, lub txias ntaub ntawv kuj yuav tsum tau mus tiv thaiv cov khoom thiab ua hauj lwm hais los ntawm overheating. Piv txwv li, txias lubricants rau metalworking pub rau optimize qhov kub thiab siab nyob siab. Tej nyiaj raws li ib tug tshwm sim, tsis yog tso cai rau koj kom qhov kev kawm ntawm cov cutters, tab sis tseem kom qhov kev kawm ntawm lub resulting cov khoom. Tseem muaj tshwj xeeb kev tiv thaiv txhais tau tias nyob rau hauv uas lub haum yog los muab kev qhia xeb, insulating thiab sealing zog. Pawg no yog cov feem ntau cov ntaub ntawv uas nyob rau hauv kev tsim kho.

coolants

Tej roj nplua nyeem yog tsim los ntawm ib tug tshwj xeeb daim ntawv qhia. Muaj yooj yim ntxawg compositions, raws li zoo raws li kev hloov kho, uas yog npaj los muab kev ua tau zoo. Feem ntau cov feem ntau, lub hauv paus ua hauj lwm pab uas tsis muaj-viscosity roj sib tov. Ua therefrom coolants, uas muaj pes tsawg leeg yog tseem hloov chlorinated paraffin, zinc dialkyldithiophosphates, mnogozolnym calcium sulfonate, thiab lwm yam additives. Tej compositions yog feem ntau yog siv nyob rau hauv tej ntawm tshav kub resistant alloys thiab stainless steel qhov chaw. Nta ntawm kev txiav txim ntawm no compound yog los mus tiv thaiv lub build-up ntawm cov ntaub ntawv uas nyob rau hauv lub cuab tam. Daim thiab thov ib tug tsis tshua muaj viscosity raws li ib puag feem glubokogidrirovannoy qaub crude. Ua hauj lwm kua rau siv nyob rau hauv no raws EDM tshuab ntawm cov zaubmov ntawm lub hwj chim, nyob rau hauv qhov kev siv ntawm cov xov xa ua hauj lwm thiab Smith nyob ntau lawm kab.

Main yam ntxwv ntawm cov dej

Tsos yam ntxwv xws kua sib txawv ntau heev nyob rau hauv lub siv additives. Feem ntau, qhov no yog ib tug tsis tshua muaj viscosity loj xim av, ntxoov uas tej zaum yuav sib txawv. Los ntawm qhov seem yus pom ntawm cov ua hauj lwm muaj nuj nqi ntawm ib qho ntawm cov tseem ceeb tshaj plaws yam ntxwv yog tus ceev. Standard lubricant muaj pes tsawg leeg nrog cua txias ua rau muaj ib tug ntom nyob rau hauv cov ntau los ntawm 1100 mus 1200 kg / m ^3. Txawm li cas los, qhov no tus nqi tej zaum yuav varied thaum lub sij hawm siv thiab ntawm cov concentrate. Tsis tas li ntawd coolants muaj active ions nyob rau hauv tej yam formulations. 1% aqueous tov ntawm cov nqi no yuav ua tau txog 10 pH. Manufacturers feem ntau pom zoo kom siv ntawm cov concentrated compositions los ntawm ib yam ntawm 1-3%. Tab sis nyob ntawm seb qhov chaw ntawm lub lag luam yog ua thiab lub hom phiaj cov ntaub ntawv uas, qhov no tus nqi yuav muab ntau zog. Yog li, nws yog pom zoo kom siv 4-hprotsentny concentrate, thiab complex hlau rau lub Performance index nce mus txog 7% thiab rau lub sib tsoo muaj nuj nqi.

Nta ntawm lub standpoint ntawm coolant

Muaj ntau txoj kev uas tus me nyuam, daim ntawv thov thiab muab faib rau cov kua rau tej qhov chaw lubrication. Tsis yog txhua txhua ntawm lawv muaj kev tshwj xeeb uas yuav tsum tau rau lubricants nyob rau hauv cov nqe lus ntawm lub zog, tab sis nyob rau hauv tej rooj plaub lawv yog ib qho tseem ceeb vim hais tias lawv txiav txim rau qhov xwm ntawm tus sis raug zoo nrog lub nruab nrab. Thaum kawg, qhov no muaj feem xyuam rau cov efficiency ntawm cov nuj nqi ntawm lub substance nws tus kheej. Piv txwv li, yog tias coolant rau metalworking tshuab cov cuab yeej, ces mus rau lub fore cov kev ceev ntawm lub pub kwj. Raws li, qhov sib zog Cheebtsam, qhov ntau npaum yuav lubrication ntawm lub txiav neeg thaum lub sij hawm lub lag luam. Tsis tas li ntawd yuav siv sij hawm mus rau hauv tus account lub feem ntawm ib tug neeg hais nyob rau hauv ib cov kua. Thaum siab pub cov nqi, lawv yuav adversely cuam tshuam lub zog ntawm cov nto, deforming nws. Nyob rau hauv tas li ntawd, tshuab tswv yuav tsum coj mus rau hauv tus account qhov kub ntawm lub dav hlau thiab ua nyiaj rau tau kev kho me ntsis ntawm lub qhov tseem ceeb ntawm cov neeg los yog lwm yam tej yam kev mob ntawm cov ua hauj lwm cheeb tsam.

Kev thiab kev kawm ntawv zog

Basic zoo yog los xyuas kom meej pom cua txias thiab lubricating nyhuv. Tsis tas li ntawd, nyob rau hauv tej cheeb tsam ntawm lub high school yuav tsum tau rau tu functionality, uas tso cai rau tus txheej txheem ntawm lub mechanism nyob rau hauv ib tug raws sijhawm los ntxuav lub saum npoo ntawm lub qhov chaw. Ntxiv zoo, uas yog muab tej txiaj ntsim uas niaj hnub txiav kua, xws li bactericidal, ecology, kev tu cev, tshuaj lom neeg kuj thiab huab kub. Nws yog ib qho tseem ceeb los ua tim nyob rau hauv lub siab hais tias cov lubricating Cheebtsam thiab muab lawv tus kheej ib tug txiav txim tshuaj los rau ib tug ntau yam ntawm cov ntaub ntawv, yog li ntawm cov kev xaiv ntawm txhais tau tias yuav tsum tau tiv kev txom nyem tiv thaiv qhov zoo ntawm cov kua nrog lub hom phiaj khoom.

ntawm ntau yam coolant

Lub ntsiab kev faib lubricating kua rau lub txias nyhuv yog raws li nyob rau hauv lub keeb kwm ntawm cov txhais tau tias. Cov feem ntau muaj roj, uas yog siv nyob rau hauv kev lag luam thiab cov muaj sector. Feem ntau nws yog ib tug ua kua roj, ntxiv modifiers. Ib qho ntawm feem nrov hom ntawm cov additives kuj coarsely dispersed roj emulsion, uas tsim nyob rau hauv lub aqueous nruab nrab. Ruaj microemulsion hom coolants cia txoj kev semisynthetic los yog hluavtaws organic tebchaw raws li. Muaj proliferated thiab Fast evaporating tsawg kub sib tov, raws li nyob rau hauv lub halogenated hydrocarbon nrog lub additives.

Kev siv cov coolant

Cov feem ntau lug siv lubricants tau nyob rau hauv zus tau tej cov hlau qhov chaw, raws li zoo raws li lawv ua. Lawv tsis tsuas yog tiv thaiv cov ua hauj lwm cov khoom los ntawm ntxov ntxov coj, tab sis kuj zoo ntawm manufactured khoom. Ob txhais qhov chaw nyob rau hauv qhov kev thov rau tej ntaub ntawv yuav tsum tau ntaus nqi rau qhov kev siv kev lag luam. Nyob rau hauv qhov kev lag luam, siv cov coolants yog tshwm sim los ntawm lub siab xav mus muab kev tiv thaiv zoo lub tsev ntaub ntawv, zoo nkauj thiab insulating coatings.

Xyuas ntawm producers

Ntawm cov coob producers ntawm coolant peev xwm yuav txawv lub tuam txhab Proma, "Univeko" thiab "Messer". Thawj hom tau ua nto moo los ntawm lub txais txhais tau tias zoo ntawm securely ua co rau txias thiab kub txoj kev. Neeg xyuas ntawm cov kua taw tes kom paub tias nyob rau hauv cov txheej txheem yog ua tau rau txo kev kawm sib yuav, ua kom tsim tau thiab ua rau kom cov neeg. "Univeko" lub tuam txhab tsim nyob rau tam sim no theem thiab zus tau tej cov lubricating kua. Qhov no pab pawg neeg ntawm tebchaw yog ua raws li xeb inhibitors thiab tshuab txais aqueous ib puag ncig, uas yog tshwj xeeb tshaj yog menyuam los ntawm cov kev pab tsim kho sector. Raws li rau lub hom "Messer", nws cov khoom nce siv nyob rau hauv high-precision machining hauj lwm. Qhov zoo ntawm cov xws kua cov neeg siv xws li siab anticorrosive zog mikrobobrozheniyu tsis kam, thiab tej kev dawb huv.

Niaj hnub nimno technology ua los ntawm cov hlau qhov chaw uas maj mam txav deb ntawm cov tsoos cov neeg kho tshuab txoj kev ntawm lub hwj. Tiv thaiv no tom qab, thiab txo tau ntawm kev tiv thaiv thiab ua rau kom lub sustainability ntawm cov kev pab cuab yeej siv. Cuaj kaum nws tshua muaj kev lag luam uas txiav kua nruab nrog cev tseem tseem ceeb. Qhov no yog feem ntau qhov kev siv, engineering, tshuaj thiab hluav taws xob engineering. Ib qho ntxiv uas yog tias nyob rau hauv heev tshwj xeeb qhov chaw yuav tsum tau ntau sophisticated nyob rau hauv lawv txoj kev thiab ua hauj lwm zoo zog ntawm cov ntaub ntawv, uas yuav tsum siv high-tech additives thiab modifiers.
