Hauv kev lag luam ntau lawm, ntau qhov txuas koom nrog kev kho cov roj thiab roj, los ntawm cov khoom lag luam hauv cov khoom lag luam hluav taws xob ntau lawm rau cov khoom siv txhua hnub. Lub xub ntiag ntawm cov roj thiab roj yuav yog ob qho tib si tsis muaj cov khoom siv hauv cov txheej txheem ntau lawm thiab ib qho kev khuam siab rau kev ua tiav ntxiv. Txij ntawm no, degreaster ua si ib lub luag haujlwm tseem ceeb. Nws yog zoo li "tej yam yees siv kev nyab xeeb ntxuav, uas tuaj yeem hloov roj los ntawm cov khoom muaj ntau yam thiab ua kom cov khoom lag luam du ntau lawm thiab cov khoom lag luam zoo.
Tus txheej txheem ua hauj lwm ntawm Dephareer yog tsuas yog raws li cov txheej txheem xws li emulsification, saponification, dispersion, thiab kev sib cais. Thawj yog emulsification. Surfactant hauv degreasing tus neeg sawv cev tuaj yeem txo cov nyiaj nro ntawm cov roj-dej sib cuam tshuam, yog li cov roj dej tuaj yeem xa tawm hauv dej kom ruaj khov. Thaum cov pab pawg ua rau muaj kev sib cuag, cov pab pawg lipophilic ntawm cov roj, thaum lub hnab ntim dej yuav ntsej muag rau hauv theem, thaum lub hnab ntim khoom thiab tso cai rau nws mus rau hauv dej. Txheej txheem saponification hom saponifiable roj xws li tsiaj thiab cov roj cog. Nyob rau hauv alkaline cov xwm txheej, roj thiab cov rog thiab cov rog thiab cov tshuaj kho mob nrog alkali los ua cov xab npum thiab glycerol. Xab npum muaj qhov zoo emulsifying thiab stainping muaj peev xwm, ntxiv pab tshem cov roj thiab roj. Cov nyhuv dispersing hais txog lub peev xwm ntawm cov roj uas tsis sib xws rau hauv dej, tiv thaiv kom lawv los ntawm re Aggregating rau ntawm cov khoom ntawm cov khoom. Thiab cov roj ntsha sib cais yog tias rau qee cov roj tshwj xeeb, qee yam hauv cov khoom siv hauv cov khoom siv tau ncaj qha rau lawv, ua rau lawv txhawm rau tshem tawm ntawm qhov khoom.
Raws li cov khoom xyaw sib txawv thiab cov kev siv hluav taws xob, feem ntau yog muab faib ua alkaline degreasers, acidic degreasers, thiab cov kuab tshuaj raws li degrehaters. Alkaline degreaser yog qhov dav tshaj plaws siv hom ntawm cov tshuaj, uas feem ntau muaj cov tshuaj alkaline xws li qee qhov surfactanate thiab ntxiv. Alkaline degreasters tau zoo degreing cuam tshuam rau tsiaj thiab zaub roj thiab ntxhia roj, thiab yog tus nqi qis thiab nyab xeeb siv. Txawm li cas los xij, nws yog ib qho tsim nyog los tswj kev tswj hwm kev pom zoo thiab kub thaum siv kom tsis txhob muaj corrosion ntawm cov khoom ntxuav kom huv tib yam li hlau. Acidi Didaser feem ntau yog siv los tshem tawm roj thiab oxide cov nplai ntawm cov hlau. Nws yog mas tsim ntawm cov kua qaub xws li sulfuric acid, ua ke nrog qee cov xeb uas tsis muaj mob thiab surfactants. Cov degreasing ceev ntawm acidic degreaser yog nrawm, thiab nws muaj qhov kev tshem tawm tau zoo rau qee cov roj av thiab oxidation txheej. Txawm li cas los xij, nws muaj cov qib siab rau cov cuab yeej thiab cov ua haujlwm, thiab kev siv tsis raug yooj yim tuaj yeem ua rau muaj kev nyab xeeb. Cov kuab tshuaj raws li cov tshuaj lom organic yog suav nrog cov roj uas muaj zog, thiab haum rau kev ntxuav kom huv si uas xav tau kev siab Cov. Txawm li cas los xij, cov kuab tshuaj raws li cov neeg muaj kuab fab feem ntau yog qhov muaj zog thiab cov nplaim taws thiab muaj kev nyab xeeb thiab hluav taws kub tau coj mus rau hauv kev siv. Nyob rau tib lub sijhawm, lawv cov nqi yog tus nqi siab thiab lawv kuj muaj qee yam cuam tshuam rau ib puag ncig.
Degite agents muaj ntau cov ntawv thov hauv ntau thaj teb. Hauv kev lag luam ua lag luam, hlau seem yuav muaj paug nrog cov roj txiav ntau, roj lubricating thiab lwm cov roj thaum ua haujlwm. Yog tias cov roj no tsis raug tshem tawm hauv lub sijhawm, nws yuav cuam tshuam rau qhov zoo ntawm electructent electroplating, pleev xim, vuam thiab lwm yam txheej txheem. Degite agents tuaj yeem tshem tawm cov roj no, ua kom qhov kev nyiam huv ntawm cov hlau, thiab txhim kho kom zoo thiab ua tau zoo ntawm kev ua tiav. Hauv kev tsim kho tsheb kev lag luam, degreing kho kho cov khoom siv tsheb yog cov kauj ruam tseem ceeb hauv kev ua kom muaj txiaj ntsig zoo thiab kev pabcuam lub neej ntawm cov tsheb. Txij los ntawm cov tseem ceeb ua ke xws li lub cav thiab kis mus rau lub plhaub lub cev, nruj me ntsis kev kho kom ntseeg tau tias cov nplaum thiab corrosion tsis zoo ntawm cov txheej. Hauv kev lag luam hluav taws xob, kev tsim cov khoom hluav taws xob yuav tsum huv, thiab cov khoom siv roj me me tuaj yeem cuam tshuam thiab kev ntseeg tau ntawm cov hluav taws xob. Degreasing cov neeg sawv cev tau siv dav hauv kev ntxuav cov txheej txheem hluav taws xob xws li cov hluav taws xob hluav taws xob thiab cov chips kom ntseeg tau qhov zoo thiab ruaj khov ntawm cov khoom siv hluav taws xob. Tsis tas li ntawd, degrehaters tseem ua lub luag haujlwm tseem ceeb hauv kev lag luam xws li plastics, roj hmab, thiab iav, thiab iav, thiab cov iav, thiab iav, thiab cov iav, thiab cov iav, thiab cov iav, thiab iav, thiab cov iav, thiab iav, thiab cov iav, thiab cov iav, thiab iav, thiab cov iav, thiab iav, thiab cov iav, thiab cov iav, thiab cov iav, pab txhim kho cov khoom lag luam zoo thiab ua haujlwm.
Nrog rau kev siv nce ntxiv rau kev tiv thaiv ib puag ncig, kev txhim kho cov neeg sawv cev tsis tau qhia qee cov qauv tshiab. Ntawm ib sab tes, txoj kev loj hlob ntawm ntau ib puag ncig zoo thiab muaj txiaj ntsig degreasing cov neeg sawv cev tau ua qhov tseem ceeb ntawm kev lag luam. Piv txwv li, txhim kho phosphorus dawb thiab nitrogen pub dawb cov neeg sawv cev kom txo cov pa phem ib puag ncig; Kawm cov muaj pes tsawg leeg ntawm biodegradable kom txo lawv cov kev cuam tshuam rau cov ecosystems. Ntawm qhov tod tes, cov neeg muaj tswv yim ntse ua kom muaj zog rau cov tshuab thov maj mam yooj yim. Los ntawm sensors thiab tswj cov tshuab, ntau yam tsis muaj zog thaum lub sij hawm ua haujlwm tau saib xyuas lub sijhawm, thiab qhov nyiaj thiab cov kev siv tau hloov kho raws li Txhawm rau qhov tseeb qhov xwm txheej, ua tiav kev tswj hwm thiab ua kom zoo dua ntawm cov txheej txheem degreast, txhim kho kev ua tau zoo thiab zoo, thiab txo cov nqi ntau lawm, thiab txo cov nqi ntau lawm, thiab txo cov nqi ntau lawm, thiab txo cov nqi ntau lawm, thiab txo cov nqi tsim khoom.
Raws li qhov tsis tseem ceeb thiab cov khoom tseem ceeb hauv kev ua teb kev lag luam tu, degrehales ua si lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub. Nws cov kev txhim kho txuas ntxiv thiab kev tsim kho tshiab yuav muab cov kev txhim kho ntau dua rau kev txhim kho ntawm kev lag luam kev lag luam ntawm ib qho kev taw qhia ntxiv thiab ntse dua. Nrog rau kev nce qib nruam ntawm kev siv thev naus laus zis, nws ntseeg tias degreasing cov neeg sawv cev yuav muaj dav daim ntawv thov kev cia siab thiab qhov chaw loj hlob yav tom ntej.
