Pali mitundu yambiri yaZosokonezandipo amagwiritsidwa ntchito kwambiri.Njira ya "kuponderezedwa kwa thovu" ndi "kusweka kwa thovu" kwa defoamer ndi: pamene defoamer imawonjezeredwa ku dongosolo, mamolekyu ake amagawidwa mwachisawawa pamwamba pa madzi, kulepheretsa mapangidwe a filimu yotanuka, ndiko kuti, kuthetsa. m'badwo wa thovu.Pamene dongosolo limapanga chithovu chochuluka, onjezerani defoamer, mamolekyu ake nthawi yomweyo amafalikira pamwamba pa chithovucho, amafalikira mofulumira, amapanga filimu yopyapyala kwambiri, kufalikira, kulowa mkati, ndikulowa m'magulu, motero m'malo mwa khoma lopyapyala. ya filimu yoyambirira ya thovu.Chifukwa cha kupsinjika kwake kocheperako, imathamangira kumadzimadzi okhala ndi kupsinjika kwakukulu komwe kumatulutsa thovu, kotero kuti mamolekyu a defoamer okhala ndi kupsinjika pang'ono akupitiliza kufalikira ndikulowa pakati pa mawonekedwe amadzi amadzimadzi, ndikupangitsa khoma la filimu kukhala lochepa kwambiri, ndipo chithovu chimakhudzidwanso ndi malo ozungulira.Wosanjikiza filimuyo wokhala ndi kupsinjika kwakukulu amakoka mwamphamvu, kotero kuti kupsinjika kozungulira chithovu kumakhala kosakwanira, komwe kumabweretsa "kusweka kwa thovu".Mamolekyu a defoamer omwe sasungunuke m'dongosolo adzalowanso pamwamba pa filimu ina ya chithovu, ndi zina zotero, chithovu chonse chidzawonongedwa kwathunthu.

Kupanga ndi kupanga zokutira kudzatulutsa thovu kumlingo wosiyanasiyana.Mbadwo wa thovu umalepheretsa kuyenda bwino kwa kupanga ndi kumanga, ndipo nthawi yomweyo kumabweretsa zolakwika ku filimu yomaliza yophimba.Kusankhidwa koyenera kwa defoamer yoyenera kumatha kutsimikizira kupita patsogolo kwabwino kwa kupanga zokutira ndi kumanga.
Ntchito ya defoamer: kuwononga filimu yamadzimadzi pamwamba pa kuwira, kuteteza mapangidwe a kuwira ndikulimbikitsa kugwa kwa kuwira.Defoamer imagwiritsidwa ntchito ngati thovu lalikulu, ndipo microfoam iyenera kugwiritsidwa ntchito limodzi ndi degassing ndi defoaming.
Mawonekedwe a Defoamer: The defoamer ndi yosasungunuka mkatikati, koma imatha kulowa ndikubalalika pakati mu mawonekedwe a ma microdroplets.Kutalika kothandiza kwambiri kwa ma microdroplets a defoamer ndikofanana ndi makulidwe a khoma la thovu.
Mapangidwe a Defoamer:Zosokonezakwa zokutira zopangira madzi zimagawidwa m'mitundu yopanda silicon ndi silicon.WambaZosokonezaamapangidwa ndi zigawo zotsatirazi:
Chinthu chogwira ntchito: Imagwira ngati chinthu chothyola thovu ndi kuchotsa thovu ndi kutsika pang'ono pamwamba.Oimira amaphatikizapo mafuta a nyama ndi masamba, silika wa hydrophobic, mowa wambiri, ndi zina.
Diffusion agent: Kunyowetsa emulsifier kuonetsetsa kuti tinthu tating'onoting'ono tating'ono tating'onoting'ono tafalikira ndikulumikizana ndi filimuyo ndikufalikira.Pali non(octyl) phenol polyoxyethylene ether, sopo mchere ndi zina zotero.
Chonyamulira: Imathandiza chinthu chogwira ntchito kuti chiphatikize ndi chithovu, ndipo chimakhala chosavuta kumwazikana munjira yotulutsa thovu.Kuphatikiza paziwirizi, imakhala ndi kupsinjika pang'ono pamwamba, imathandizira kupondereza thovu, ndipo imatha kuchepetsa ndalama.
Zinthu ziwiri ziyenera kukumana pochotsa thovu: chinthu cholowera: E=γ1+γ12-γ3 > 0, kuonetsetsa kuti defoamer ilowa mu khoma la thovu;spreading factor S=γ1-v12-γ3 >0, kuwonetsetsa kuti madontho a defoamer Diffusion akufalikira mu media media.
