Emulsol. Daim ntawv thov
Emulsols hauv metalworking
Ib qho tseem ceeb zoo ntawm ib qho emulsol yog kev sib xyaw ua ke ntawm ob txoj haujlwm: ua kom txias cov cuab yeej ua haujlwm (qee zaum lub workpiece), thiab txo qis kev sib txhuam, uas tshwm sim hauv ob qhov xwm txheej:
- Machining (tig, threading, milling, thiab lwm yam). Xws li emulsols yog siv rau tshuab dhos.
- Nrog cov txheej txheem txuas ntxiv ntawm cov yas deformation (kev ntxhov siab, knurling, kos duab). Xws li emulsols yog siv los ua cov kua (coolants) nyob rau hauv ntau txoj hauj lwm stamping tshuab, kos duab tshuab, nrog rau cov cav tov uas zoo sib xws ntawm stamping hlau thiab alloys.
Raws li lub hauv paus ntawm emulsols, cov roj ntxhia feem ntau yog noj, uas yog qhov txawv los ntawm kev txo qis viscosity. Lawv tuaj yeem yog roj I-12A, I-20A, roj transformer, thiab lwm yam. Soaps ntawm cov organic acids - naphthenic los yog sulfonaphthenic - yog siv los ua emulsifiers. Tsis ntev los no, emulsifiers tau dhau los ua dav, uas yog raws li cov khoom lag luam neoiogenic cov yam ntxwv los ntawm kev txhim kho kev tiv thaiv corrosion (piv txwv li, stearox).
Txhawm rau ua kom cov kav ntev, cov tshuaj ntxiv tau nkag mus rau hauv cov khoom lag luam emulsols, uas tau muab faib ua hom hauv qab no:
- Rog (txo cov coefficient ntawm kev sib txhuam).
- Anti-corrosion.
- Polishing.
- Antifoam.
- Tshuaj tua kab mob.
Rau kev ua hlau, nws raug nquahu kom siv emulsols EP-29, ET-2u, OM.
Emulsols hauv kev tsim kho
Qhov kev nthuav dav ntawm kev tsim kho monolithic puas tau muab rau ntau yam kev teeb tsa ua haujlwm, thaum lub sijhawm ua vaj tse yog nchuav rau hauv formwork ncaj qha rau ntawm qhov chaw tsim kho. Tsis tas li ntawd, tshem tau formwork kuj yog siv thaum pouring foundations.
Kev tsim khoom ntawm pouring nyob ntawm qhov nyuaj ntawm kev npaj ua hauj lwm nrog rau reinstallation ntawm lub formwork ntsiab. Lub dismantling ntawm nws qhov chaw yog ib qho nyuaj, vim hais tias cov seem ntawm cov pob zeb ua raws li cov hlau ntsiab ntawm formwork. Yav dhau los, cov roj av zoo tib yam tau siv los txo kev sib txhuam. Txawm li cas los xij, cov khoom siv roj no yog cov kua nplaum heev, flammable, thiab tawm cov stains uas nyuaj rau ntxuav tawm. Nws yog emulsols uas tau los ua cov tebchaw uas tuaj yeem siv tau zoo rau kev ua haujlwm.
Tom qab lubrication ntawm formwork nrog emulsols (piv txwv li, EGT, EX-A qib), ib zaj duab xis nyias yog tsim nyob rau saum npoo ntawm cov hlau qhov chaw ntawm lub formwork, uas yog tsim los ntawm hais tias tsawg viscosity roj dispersed nyob rau hauv dej los yog nyob rau hauv hluavtaws. sau ntawv. Kev siv emulsols pab txhawb kev rhuav tshem ntawm formwork los ntawm cov pob zeb loj thiab tiv thaiv kev txhim kho cov txheej txheem corrosion.
Ib qho tshwj xeeb ntawm emulsol qib kev tsim kho yog lawv qhov kev ua haujlwm ruaj khov ntawm qhov tsis zoo ntawm huab cua sab nraud.
