Yog li ntawd, ib tug tsis tuaj yeem ua yam tsis muaj kev siv tshwj xeeb.

Thawj kauj ruam ua ntej pleev xim yog ua ntej kho lub cev. Thaum lub sijhawm ua haujlwm no, cov xim qub raug tshem tawm ntawm lub tsheb. Tom qab ntawd cov hlau yuav tsum tau degreased, thiab tom qab ntawd cov neeg tsav tsheb ntsib teeb meem. Cia peb sim seb yuav ua li cas cov chaw degreased ntawm cov tsheb niaj hnub no thiab yuav ua li cas kom raug thiaj li tau txais txiaj ntsig zoo tshaj plaws.

Yuav muaj nyiaj dab tsi

Feem ntau, txhawm rau tiv thaiv cov greasy film uas nyob ntawm lub cev, cov neeg tsav tsheb hauv txoj kev qub siv lint-dawbwipes kho nrog tej yam hnyav. Cov kws tshaj lij tsis pom zoo ua qhov txheej txheem no. Qhov kev xaiv no tsuas yog tsim nyog thaum nws tsim nyog los ua ib qho chaw me me xwb. Yog tias koj saib ntau yam kev npaj rau kev npaj ua haujlwm ua ntej tha xim, uas tau tsim hnub no, koj tuaj yeem xaiv ntau yam cuab yeej uas degrease hlau nto. Cov no yog ntau cov kuab tshuaj thiab cov khoom ntawm cov organic keeb kwm, emulsions, nrog rau cov kev daws teeb meem tshwj xeeb, uas suav nrog cov tshuaj detergent additives.

Cov kws tshaj lij pom zoo kom siv tom kawg. Cov tshuaj no ua tiav thiab ntseeg siab tsis yog tsuas yog cov greasy zaj duab xis xwb, tab sis kuj tua cov av thiab cov teebmeem ntawm corrosion tsis zoo.

Ntsuj Plig Dawb Huv

Ib qho ntawm cov kuab tshuaj organic no yog cov ntsuj plig dawb paub zoo. Nws yog siv nyob rau hauv thawj theem ntawm lub cev ua. Tom qab ntawd, hauv cov kauj ruam yooj yim dua, kev sib xyaw ntawm cawv nrog phosphoric acid yog siv. Xws li ib qho kev daws yuav ua kom huv si tshem cov kab ntawm cov roj los ntawm cov hlau nto. Tab sis muaj lwm yam tshuaj tshaj li qhov koj tuaj yeem degrease qhov chaw ntawm lub tsheb. Ib tus neeg sawv cev zoo li no yog trichlorethylene. Qhov no yog cov neeg sawv cev nto moo tshaj plaws ntawm pawg ntawm cov organic solvents. Nws nkag mus rau hauv cov tshuaj tiv thaiv thaum muaj kev sib cuag nrog txhuas lub cev. Nyob rau tib lub sijhawm, cov khoom siv hluav taws xob raug tso tawm thaum lub sijhawm cov tshuaj tiv thaiv, uas ua rau muaj kev pheej hmoo ntawm hluav taws thaum muaj xwm txheej. Kev poob siab heev uas siv nws.

Yog tias trichloethylene hnov mob nrog dej, ces cov nplaum nplaum yuav tsim rau ntawm lub cev, uas tsis yooj yim rau tshem tawm. Yog tias tsis muaj lwm txoj kev xaiv dua li degrease qhov chaw ntawm lub tsheb, cov tshuaj no yuav ua. Tab sis nws tsuas ua haujlwm thaum tsis muaj dej noo ntawm txheej.

Kev npaj tshwj xeeb rau kev ua haujlwm

Cov kws tshaj lij uas tau pleev xim rau lub tsheb ntev ntev paub thiab pom zoo kom siv cov khoom tshwj xeeb - lawv tsis ua rau hluav taws kub, thiab tseem tsis tawm cov tshuaj lom neeg ua rau tib neeg.

Tab sis cov neeg pib tshiab feem ntau tsis quav ntsej cov lus qhia thiab liam tias "paub" txoj hauv kev zoo tshaj plaws kom degrease qhov chaw ntawm lub tsheb. Feem ntau siv roj av, roj av, acetone thiab txawm tias roj diesel siv rau qhov no. Qhov tseeb, tag nrho cov saum toj no tsuas yog siv tau thaum lub khw muag tshuaj pleev ib ce ze tshaj plaws nyob deb li ntawm 100 km.

Roj av, diesel, acetone ua lwm txoj hauv kev dawb huv

Cov neeg uas tsis tau ua haujlwm ua ntej pleev xim ua ntej feem ntau tsis meej pem cov dej ntxhia nrog lwm yam khoom xws li roj av, kerosene thiab roj av - tag nrho cov kua no zoo ib yam ntawm cov ntxhiab tsw.

Tab sis qhov sib txawv ntawm lawv yog qhov me. Lawv yog cov sib tov ntawm hydrocarbons uas yog tsim los ntawm distillation ntawm cov roj feem. Txhua yam tshuaj zoo kawg nkaus yaj ntau yam mastics, bitumen stains lossis rog. Tab sis diesel thiab kerosene yog qhov nyuaj heev los ntxuav tawm, txawm tias nyob rau hauv txoj cai raudegreasing lawv tsim nyog. Kev cob qhia lub tsheb ntxuav siv cov roj av, tab sis lawv siv cov cuab yeej tshwj xeeb uas ua kom yooj yim tshem tawm cov kab mob thiab cov ntxhiab tsw. Hauv cov chaw nres tsheb, kev ua haujlwm hauv txoj kev no yuav muaj kev phom sij. Acetone siv tau nrog ceev faj heev, nrog rau cov kuab tshuaj No. 646 lossis 645.

YAntisilicon

Anti-silicone, uas degreases qhov chaw, yog qhov kev xaiv zoo tshaj plaws rau txhua tus neeg tsav tsheb zoo tib yam uas txiav txim siab npaj lub cev rau pleev xim nrog lawv tus kheej tes.

Cov txheej txheem no yuav xav tau kev siv hluav taws xob ntau zaus. Ib qho tseem ceeb yog polarity. Nws yog txiav txim los ntawm hom hlau. Lub anode yuav txuas rau steel degreasing, thiab cov cathode yuav siv rau cov hlau uas tsis yog-ferrous.

Kev ntxuav ntau theem

Ua ntej tshaj plaws, lub cev ua haujlwm yog kho nrog tus ntsuj plig dawb. Kuv yuav ua li cas yog tias muaj cov cim ntawm corrosion ntawm qhov chaw? Hauv qhov no, nws yog ib qho tsim nyog los kho qhov chaw siv phosphoric acid nrog cawv. Cov tshuaj no yog sib xyaw ntawm ethylcawv nyob rau hauv ib tug ratio ntawm 15%. Ib feem ntawm cov dej thiab phosphoric acid kuj sib xyaw hauv qhov sib piv ntawm 1 mus rau 5. Tsis tas li ntawd, ib qho emulsifier yog siv - wetting agent OP-7 nyob rau hauv ib tug npaum li cas ntawm 0.5%. Koj kuj xav tau 0.1% nitrobenzene. Nws yog qhov nyuaj heev kom tau txais cov khoom sib xyaw no hauv tsev - qee cov tshuaj tsis muaj muag. Nws tseem tsim nyog nco ntsoov tias muaj pes tsawg leeg yog qhov txaus ntshai rau kev noj qab haus huv.

CV

Thaum teb cov lus nug ntawm yuav ua li cas degrease qhov chaw ntawm lub tsheb, qee qhov kev ntsuas yuav tsum raug coj mus rau hauv tus account - qhov ua tau zoo ntawm cov khoom, nws cov nqi thiab kev lag luam. Qhov kev xaiv zoo tshaj plaws yog ib qho uas ua tiav tag nrho cov kev xav tau no, tab sis nws nyuaj heev los nrhiav qee yam zoo sib xws ntawm kev muag khoom. Ntxiv rau tag nrho cov xwm txheej no, nws yog ib qho tsim nyog yuav tsum tau coj mus rau hauv tus account qhov kev puas tsuaj uas cov khoom yuav muaj nyob rau hauv cov hlau lossis rau tib neeg kev noj qab haus huv.
