Antifootar amagwiritsidwa ntchito kuchepetsa kuchepa kwa madzi, yankho ndi kuyimitsidwa, kupewa mapangidwe achitsufu, kapena kuchepetsa chithovu, kapena kuchepetsa chithovu, kapena kuchepetsa chithovu chopangidwa ndi mafakitale. Antiformars wamba ali motere:
I. Mafuta achilengedwe (nee soybean, mafuta a chimanga, etc.)
Ubwino: Kupezeka, koyenera kugwiritsa ntchito mosavuta.
Zoyipa: Ndikosavuta kuwonongeka ndikuwonjezera mtengo wa asidi ngati sasungidwa bwino.
Ii. Mowa Wambiri
Mowa wambiri wa carbonar ndi molekyulu yolimba ndi hydrophobity ndi ofooka hydrophilicity, omwe ndi antifoamer m'madzi. Kuledzera kwa mowa kumagwirizana ndi kusungunuka kwake ndikusiyana kwake mu yankho. Mowa wa C7 ~ C9 ndi antifoamers othandiza kwambiri. Kamera yayitali ya c12 ~ C22 imakonzedwa ndi ma emulsifiers yoyenera ndi tinthu tating'onoting'ono ta 4 ~ 9μm, ndi 20% emulsion, ndiye kuti, decomer m'madzi. ESTER enanso amakhalanso ndi zotsatira za penicillin kupesa, monga phenyletthal Oleate ndi Lairyl Phenyl Pheyaltate.
Iii. Polyteter antifoamers
1. Gp antifoamers
Opangidwa ndi kuwonjezera polymerization wa ma propyne oxide, kapena chisakanizo cha ethylene oxide ndi ma propylene oxide, ndi glycerol monga wothandizira woyamba. Ili ndi hydrophilicity wosauka komanso wosungunuka wotsika mu thomu, motero ndizoyenera kugwiritsidwa ntchito mu mphamvu yopyapyala. Popeza kuthekera kwake kotalikirako kuli kwapamwamba kuposa kusokoneza, ndikoyenera kuwonjezeredwa mu basel sing'anga kuti ilepheretse kuwombera.
2. GPE antifoamers
Ethylene oxide amawonjezeredwa kumapeto kwa polycropylene glycol ulalo wa gp a antifol a antifoln kuti apange axyclerol ndi Mapeto a hydrophilic. GPE Antifoamer ali ndi hydrophilicity yabwino, kuthekera kwamphamvu, komanso kumakhala kosungunuka kwakukulu komwe kumapangitsa nthawi yokonzanso nthawi yochepa kwambiri pantchito. Chifukwa chake, imagwira ntchito bwino mu msuzi wa ma virus.
3.. Gpes antifoamers
Chuma chotchinga ndi ma hydrophobic unyolo onse ndi maunyolo amapangidwa ndi kusindikiza unyolo wa antiforaters ndi hydrophobic prearate. Mamolekyu okhala ndi kapangidwe kameneka amayamba kusonkhana pa mawonekedwe a gasi, motero ali ndi mphamvu zapamwamba komanso zothandiza kwambiri.
Iv. Polyteter osinthika silicone
Polythetter adasinthidwa sicone antifoamers ndi mtundu watsopano wa zotchinga kwambiri. Ndi mtengo wokwera mtengo ndi maubwino obalalitsidwa bwino, kuthekera kwamphamvu kwa chikopa, kukhazikika, osavulaza komanso opanda vuto komanso otsika ofowoka a antifoamers. Malinga ndi mawonekedwe osiyanasiyana amkati, imatha kugawidwa m'magulu awiri otsatirawa:
1. Copalymer ndi -si-oc- toner okonzeka ndi acid monga chothandizira. Decomer iyi ndiyosavuta ku hydrolysis ndipo sakhazikika bwino. Ngati mthenga wa Amine alipo, amatha kusungidwa kwa nthawi yayitali. Koma chifukwa cha mtengo wake wotsika, zomwe zingakhale zotheka.
2. Cuovolimer womangidwa ndi - SI-Cond ali ndi mawonekedwe okhazikika ndipo amatha kusungidwa kwa zaka zopitilira ziwiri pansi. Komabe, chifukwa chogwiritsa ntchito platinam okwera mtengo monga chothandizira popanga, mtengo wopanga mtundu wamtunduwu uli wokwera, chifukwa chake sichinagwiritsidwe ntchito kwambiri.
V. Silicon anticon antifoamer
... Chaputala chotsatira.
