Roj-resistant roj yog tsim los tiv thaiv ntau yam txheej txheem thaum ua haujlwm ntawm qhov kub thiab txias. Nws tiv thaiv kev hnav ntawm qhov chaw rau lub sijhawm ntev thiab ua haujlwm tau zoo ntawm qhov kub thiab txias yam tsawg 150 degrees. Feem ntau ntawm cov khoom siv hauv cov nroj tsuag thiab cov chaw lag luam tsis tas yuav siv cov ntaub ntawv zoo li no, yog li lawv tau tsim nyob rau hauv tsawg qhov ntau thiab, raws li txoj cai, los ntawm kev txiav txim.
Kev piav qhia
Cov khoom sib txawv ntawm cov khoom siv roj nplua nyeem, feem ntau hauv cov khoom siv raw. Nws yog qhov kim dua thiab suav nrog cov khoom siv tshwj xeeb uas xav tau los ua kom sov ua haujlwm thiab cov roj hluavtaws-raws li cov thickeners. Qhov no yog vim cov pa roj nplua nyeem tsis zoo nyob rau hauv cov xwm txheej zoo li no thiab siv sai heev.
Type
Muaj ntau ntau yam, ntawm cov hauv qab no tsim nyog qhia:
- tshav kub-resistant sodium roj tau dhau los ua tsawg dua thiab nrov dua nyob rau lub sijhawm, vim nws ua haujlwm tsis zoo rau cov kev xaiv niaj hnub uas tuaj yeem tiv taus qhov kub thiab txias.
- Calcium complex cov ntaub ntawv yog qhov txawv ntawm tus nqi tsim nyog thiab kev faib tawm ntau. Raws li calcium soaps muab tau los ntawm fatty acids, lawv muaj thickeners thiab disulfide, vim lawv muaj zog adhesion thiab anti-kev sib txhuam yam ntxwv.
- Silica gel siab kub bearing roj yog tsim rau ntau yam kev siv. Nws yog pheej yig dua li hluavtaws counterparts vim roj puag.
- Pigment formulations yog tsim los ntawm cov thickeners tshwj xeeb thiab zoo tagnrho rau kev kub ceev hluav taws xob tshuab bearings.
- Cov ntaub ntawv Polymer muaj cov yam ntxwv tiv thaiv kev sib txhuam thiab yog tsim los ntawm cov ntaub ntawv xws li PTFE thiab polyurethane.
- tshav kub-resistant graphite roj yog tsim los rau cov ntsiab lus qis thiab khaws nws cov yam ntxwv yav dhau los ntawm qhov kub siab tshaj 350 degrees. Cov yam ntxwv tshwj xeeb yog qhov tsis muaj zog tsawg, zoo heev EP thiab cov yam ntxwv kev ua haujlwm.
Hnub no, muaj ntau dua 30 hom ntawm cov roj nplaum uas tiv taus cua sov uas tau txhim kho thiab hloov cov khoom siv tsis tu ncua.
siv thaj chaw
tshav kub-resistant silicone roj yog indispensable nyob rau hauv ceramic, bakery, ntawv thiab lub zog industries, nws kuj xyuas kom meej lub lag luam ntawm bearings nyob rau hauv lub ntsiab ntawm lub tsheb thiab cov tsheb ua liaj ua teb, taug qab tsheb. Nws tuaj yeem siv rau hauv cov txheej txheem thiab cov rooj sib txoos uas tau raug cov dej tsis tu ncua vim muaj cov yam ntxwv ntawm cov dej-resistant siab. Yog tias tsis muaj cov ntaub ntawv no, nws tsis tuaj yeem xav txog kev ua haujlwm ntawm cov xauv ntawm chav ziab khaub ncaws, kiln, conveyor siv, kiv cua thiab twj tso kua mis bearings.
Vim yog siv cov khoom sib xyaw, cov khoom thauj ntawm qhov chaw rub tawm raug txo, uas ua rau lub sijhawm ua haujlwm. Nyob rau tib lub sijhawm, muaj cov tshuaj ntxiv tshwj xeeb thiab cov yam ntxwv viscosity ua kom muaj kev noj tsawg kawg nkaus. Txhawm rau tswj hwm tus yam ntxwv zoo ib yam, nws yog qhov tsis xav kom sib xyaw ua ke ntawm ntau hom, txij li lawv txhua tus muaj lub hom phiaj tshwj xeeb thiab cov khoom.
Heat Resistant Bearing Grease
Cov khoom siv tau faib ua raws li kev ua haujlwm, cov khoom xyaw thiab sib xws. Cov qauv tuaj yeem yog khoom, yas lossis kua. Qhov kawg ob txoj kev xaiv yog colloidal compositions uas muaj ib tug dispersed theem thiab ntau yam additives. Cov ntaub ntawv yas hom pom lawv daim ntawv thov hauv cov cables nrog ntau cov hlua, ntsia hlau iav, hinges thiab ntau yam bearings. Thaum siv lawv, koj yuav tsum coj mus rau hauv tus account ntau lub ntsiab lus uas txiav txim siab kev ua haujlwm zoo:
- Muaj peev xwm sib tov ntau yam khoom.
- Kev sib xyaw ntawm cov roj nplaum thiab cov khoom siv.
- Daim ntawv thov (tus nqi ua haujlwm, thauj khoom, qhov kub thiab txias).
High-kub cov kabmob roj tau txais nws cov khoom tom qab hnyav evaporation thiab muaj qhov tsawg kawg nkaus ntawm kev sib txhuam qhuav. Nws muaj cov binders (resins), cov thickener thiab hnyav hnyav. Nws kuj tseem muaj cov pa roj carbon thiab graphite.
Composition
Cov khoom siv los ntawm kev sib xyaw yog muab faib ua ntau hom:
- Cov roj nplua nyeem tsis muaj roj yog tsim los ntawm cov khoom tawg yooj yim uas ruaj khov ntawm txhua qhov kub. Cov no suav nrog asbestos, graphite thiab silica gel cov ntaub ntawv.
- Cov xab npum kub-tiv taus roj muaj cov ntsev ntawm carboxylic acids thiab tau muab faib ua ntau thiab yooj yim, nyob ntawm seb cov xab npum siv. Ib qho txawv txawv yog cov khoom siv sib xyaw. Cov xab npum anions siv los txiav txim seb hom khoom, uas tuaj yeem yog roj lossis hluavtaws.
- Hydrocarbon raws li formulations muaj thickeners nyob rau hauv daim ntawv ntawm hluavtaws thiab ntuj waxes, paraffin thiab ceresin.
- Cov roj hluav taws xob tiv thaiv hluav taws xob yog tsim los ntawm cov khoom siv hluav taws xob sib cais thiab tuaj yeem muaj cov kua qaub, xim thiab polymer puag.
Kev faib tawm raws lub hom phiaj
Muaj ntau qhov chaw ntawm kev siv cov khoom sib txuas, txhawm rau ua kom yooj yim ntawm kev xaiv ib lossis lwm qhov kev xaiv, lawv tau muab faib ua ntau hom raws lidestination:
- Cable xov tooj muab kev tiv thaiv corrosion thiab txo hnav.
- Sealing tso cai rau koj ua tiav qhov tsim nyog sealing ntawm cov khoom sib txuas thiab cov xov sib txuas, ua kom yooj yim rau kev ua haujlwm nrog fittings thiab kaw qhov khoob.
- Preservative tiv thaiv corrosion ntawm steel ntsiab thaum lub sij hawm cia, tsheb thauj mus los thiab ua hauj lwm.
- Anti-kev sib txhuam txo kev sib txhuam ntawm cov khoom nyob ib sab thiab tag nrho hnav.
Lub hom phiaj tseem ceeb ntawm cov kabmob yog tsim kev txav mus los hauv cov tshuab thiab cov tshuab. Tab sis tsis muaj kev saib xyuas kom zoo, nws tsis tuaj yeem ua kom muaj kev ua haujlwm zoo thiab ua haujlwm ntev. High-temperature bearing grease yog ib qho khoom siv tseem ceeb rau kev ua haujlwm tag nrho. Ib qho zoo sib xws yog tsim tshwj xeeb rau kev ua haujlwm ntawm qhov kub thiab txias. Thaum siv rau lwm yam mob, nws pib thicken thiab crystallize.
Yuav ua li cas xaiv
Thaum xaiv, nws yuav tsum tau coj mus rau hauv tus account lub loads ntawm lub mechanism, cov ntaub ntawv siv thiab ceev ntawm kev sib hloov ntawm lub ntsiab. Cov qauv ntawm cov roj nplua nyeem dhau los ua kua heev thaum cov txheej txheem ceev dhau lawm. Vim li no, nws kis tau ib ncig ntawm cov npoo, thiab kev sib txhuam ntau dhau tshwm sim ntawm qhov chaw sab hauv ntawm qhov chaw.
Kev txwv nrawm rau cov txheej txheem sib txawv sib txawv. Cov khoom siv hluavtaws yog qhov zoo rau cov chav ua haujlwm ntawm kev kub ceev. Ib puag ncig yam tseem ceeb yuav tsum raug coj mus rau hauv tus account, tshwj xeeb tshaj yog raug rau chav, acids thiabhmoov av. Rau kev ua haujlwm nyob rau hauv cov xwm txheej tsis tu ncua ntawm cov kuab tshuaj thiab cov kua qaub, yuav tsum muaj cov tshuaj tiv thaiv ntau dua.
Yam uas koj yuav tsum paub
Lub luag haujlwm ntawm cov roj nplua nyeem suav nrog tsis yog tsuas yog txo qis kev sib txhuam ntawm kev sib cuag cov qauv thiab tsim cov txheej txheem tiv thaiv. Lawv tiv thaiv cov ingress ntawm cov pa phem los ntawm ib puag ncig, tsim ntawm corrosion, muab cov cua txias ntawm cov qauv thiab cov cua sov faib. Qhov no ua rau lub neej ntawm cov cuab yeej siv thiab txo qhov kev puas tsuaj nyob rau hauv cov khoom siv ntau dhau.
Rolling bearings
Qhov ntau yam no yog qhov tseem ceeb rau ntau yam khoom siv. Khoom, kua thiab yas kub-resistant lubricants yog haum rau lawv, uas yog xaiv ib tus zuj zus, nyob ntawm seb lub hom phiaj ntawm lub mechanism. Tsis tas li ntawd, tsis tsuas yog cov txheej txheem tseem ceeb yuav tsum raug coj mus rau hauv tus account, tab sis kuj tseem muaj peev xwm siv tau hauv kev tsim khoom noj thiab cov kev cai rau kev huv ntawm chav tsev. Ntxiv nrog rau lub luag haujlwm tseem ceeb, lawv yuav tsum ua tus phooj ywg ib puag ncig thiab muab cov suab nrov tsawg kawg thaum lub sijhawm ua haujlwm.
Txawm hais tias txhua qhov sib xws tuaj yeem siv tau, cov kua roj lubrication yog qhov kev xaiv zoo tshaj vim nws cov kev sib txhuam siab thiab cov yam ntxwv ntawm cov cua kub dissipation. Cov qauv roj muaj cov khoom zoo heev nkag mus, tab sis tsis tshua muaj kev lag luam vim qhov ua tau los ntawm cov muaj pes tsawg leeg. Cov khoom siv yas thiab cov khoom siv hluavtaws yog deprived ntawm no shortcoming.tshav kub resistant lubricants. Lawv yog cov kev lag luam ntau dua thiab hais txog lawv cov yam ntxwv tsis qis dua rau lawv cov khoom siv roj.
