Defoamer ya m'badwo wachitatu ndi silicone defoamer yochokera ku polydimethylsiloxane (PDMS, dimethyl silicone mafuta).Pakadali pano, kafukufuku ndikugwiritsa ntchito kwa m'badwo uno wa defoamers akukhazikika ku China.PDMS wapangidwa ndi pakachitsulo mpweya unyolo ndi magulu organic, ndipo sangathe mwamphamvu anakonza pa thovu madzi filimu, kotero kuti thovu adzaphulika.Low mamasukidwe akayendedwe PDMS ali wabwino defoaming katundu ndi mkulu mamasukidwe akayendedwe PDMS ali ndi katundu wabwino defoaming.
Ubwino wa silicone defoamer
Ili ndi inertia yabwino yamankhwala ndipo ndizovuta kuchita ndi zinthu zina.Itha kugwiritsidwa ntchito mu acid, alkali ndi mchere.
Good physiological inertia, angagwiritsidwe ntchito m'mafakitale zakudya ndi mankhwala, ndipo alibe kuipitsa chilengedwe.
Ili ndi kukhazikika kwabwino kwa kutentha komanso kutsika kochepa, ndipo ingagwiritsidwe ntchito pa kutentha kwakukulu.
The mamasukidwe akayendedwe otsika ndi kufalikira mofulumira pa mawonekedwe gasi-zamadzimadzi.
Kupanikizika kwapamtunda mpaka 1.5-20 Mn / M (76 Mn / m pamadzi).
Sikophweka kusungunuka ndi surfactant mu foaming system.
Mlingo wochepa, kukhuthala kochepa komanso kutsika kwamoto.
Zoyipa za silicone defoamer
1. Ndizovuta kumwazikana m'madzi.
2. Chifukwa amasungunuka m'mafuta, mphamvu yowonongeka mu dongosolo la mafuta imachepetsedwa.
3. Kukana kutentha kwakukulu.
4. Kulephera kukana kwa alkalinity amphamvu.
Mtengo wapamwamba:PDMS ndi madzi mu mafuta (O/W) emulsion opangidwa ndi silikoni girisi, emulsifier, thickener, etc., amene emulsified ndi madzi.Kuthamanga kwapamtunda kumachepa mofulumira ndipo kumakhala ndi mphamvu zotsutsana ndi thovu komanso zotsutsana ndi thovu.Amagawidwa m'magulu atatu: mafuta a silikoni, mafuta a silicone + osinthidwa poliyeti ndi polyether yosinthidwa silikoni mafuta.
Amadziwika ndi:Kuthamanga kwapansi pamtunda, ntchito yaikulu ya pamwamba ndi mphamvu yamphamvu yofooketsa.
Mlingo wochepa:Ikhoza kuletsa ndi kuswa thovu kwa ambiri kuwira TV.Ili ndi kukhazikika kwabwino kwa kutentha ndipo ingagwiritsidwe ntchito pa kutentha kwakukulu.Imagawidwa ndi polyether ndipo imakhala ndi synergistic effect.Amagwiritsidwa ntchito kwambiri pochotsa thovu mu zotsukira, kupanga mapepala, zamkati, kupanga shuga, electroplating, feteleza wamankhwala, zowonjezera, kuyeretsa madzi oyipa ndi njira zina zopangira.M'makampani amafuta, amagwiritsidwa ntchito kwambiri pochotsa gasi lachilengedwe kuti apititse patsogolo kulekana kwamafuta ndi gasi;Amagwiritsidwanso ntchito kuwongolera kapena kupondereza thovu pazida monga kuyanika kwa ethylene glycol, kutulutsa konunkhira kwa hydrocarbon, kukonza phula ndi kuthira mafuta.M'makampani opanga nsalu, amagwiritsidwa ntchito pochotsa thovu popaka utoto, kukwapula, kupanga masing ndi njira zina;Izo ntchito m`kati mankhwala emulsion ndi defoaming makampani;Amagwiritsidwa ntchito pochotsa thovu m'njira zosiyanasiyana, zowotchera komanso zotulutsa m'makampani azakudya.
