Emulsol. Mapulogalamu
Emuls mu zitsulo
Ubwino wofunikira wa emulsol iliyonse ndi kuphatikiza kwa ntchito ziwiri: kuziziritsa chida chogwirira ntchito (nthawi zina chogwiritsira ntchito), ndi kuchepetsa kukangana kotsetsereka, komwe kumachitika pawiri:
- Machining (kutembenuza, ulusi, mphero, etc.). Ma emuls amenewa amagwiritsidwa ntchito popanga lathes.
- Ndi njira mosalekeza mapindikidwe pulasitiki (kukhumudwitsa, knurling, kujambula). Ma emuls oterowo amagwiritsidwa ntchito ngati madzi odulira (zozizira) m'makina osindikizira amitundu yambiri, makina ojambulira, komanso makina omwe ali ndi mitundu yofananira ya zitsulo ndi ma aloyi.
Monga maziko a emuls, mafuta amchere amatengedwa nthawi zambiri, omwe amasiyanitsidwa ndi kuchepetsedwa kukhuthala. Atha kukhala mafuta I-12A, I-20A, mafuta osinthira, etc. Sopo wa organic acid - naphthenic kapena sulfonaphthenic - amagwiritsidwa ntchito ngati emulsifiers. Posachedwapa, ma emulsifiers afalikira, omwe amachokera ku zinthu za neoiogenic organic zomwe zimadziwika ndi zotsutsana ndi zowonongeka (mwachitsanzo, stearox).
Kuonjezera kulimba, zowonjezera zimayambitsidwa muzopanga zamafakitale emulsols, zomwe zimagawidwa m'mitundu iyi:
- Mafuta (kuchepetsa kuchuluka kwa kukangana).
- Anti- dzimbiri.
- Kupukutira.
- Antifoam.
- Antibacterial.
Popanga zitsulo, ndi bwino kugwiritsa ntchito emuls EP-29, ET-2u, OM.
Emuls mu ntchito yomanga
Kukula kosalekeza kwa zomangamanga za monolithic kumapereka ntchito zosiyanasiyana zoikamo, pomwe konkire imatsanuliridwa mu formwork mwachindunji pamalo omanga. Kuphatikiza apo, formwork yochotseka imagwiritsidwanso ntchito pothira maziko.
Kuchuluka kwa kuthira kumadalira zovuta za ntchito yokonzekera yokhudzana ndi kubwezeretsanso zinthu za formwork. Kuchotsa mbali zake kumakhala kovuta, chifukwa mabwinja a konkire amamatira kwambiri kuzinthu zachitsulo za formwork. M'mbuyomu, mafuta wamba ankagwiritsidwa ntchito pofuna kuchepetsa mikangano. Komabe, mafutawa amakhala owoneka bwino, amatha kuyaka, ndipo amasiya madontho omwe ndi ovuta kuchapa. Zinali ma emuls omwe adakhala mankhwala omwe angagwiritsidwe ntchito mogwira mtima.
Pambuyo mafuta a formwork ndi emulsols (mwachitsanzo, EGT, EX-A kalasi), filimu woonda amapangidwa pamwamba zitsulo mbali ya formwork, amene amapangidwa ndi tinthu ting'onoting'ono mafuta mamasukidwe akayendedwe otsika omwazika m'madzi kapena kupanga. nyimbo. Kugwiritsa ntchito emulsols kumathandizira kugwetsa konkriti ndikuletsa kukula kwa dzimbiri.
A mbali ya emulsol yomanga magiredi ndi ntchito yawo khola pa kutentha zoipa kunja kwa mpweya.
