1 Kusasungunuka kapena kusungunuka bwino mumadzi ochita thovu kumatanthauza kuti thovu lasweka, ndipodefoameriyenera kukhazikika ndikuyika pa filimu ya chithovu. Kwa defoamer, iyenera kukhazikika ndikukhazikika nthawi yomweyo, ndipo kwa defoamer, iyenera kusungidwa nthawi zonse.
Chifukwa chake, defoamer ili m'malo odzaza ndi thovu lamadzimadzi, ndipo ndikosavuta kufika pamtunda pokhapokha ngati ili yosasungunuka kapena yosasungunuka bwino. Insoluble kapena bwino sungunuka, n'zosavuta kusonkhanitsa pa mawonekedwe a gasi-zamadzimadzi, zosavuta kuika maganizo pa filimu chithovu, ndipo akhoza kutenga mbali pa m'munsi ndende. Kwa ma defoam omwe amagwiritsidwa ntchito m'madzi, mamolekyu azinthu zogwira ntchito ayenera kukhala amphamvu kwambiri a hydrophobic komanso ofooka hydrophilic, ndipo mtengo wa HLB uyenera kukhala wa 1.5-3 kuti ugwire bwino ntchito.
2 Kuthamanga kwapamtunda ndikotsika kuposa kwamadzi ochita thobvu. Pokhapokha pamene mphamvu ya intermolecular ya defoamer ndi yaying'ono ndipo kugwedezeka kwapansi kumakhala kochepa kusiyana ndi madzi otulutsa thovu, tinthu tating'onoting'ono ta defoamer tingamizidwe ndikukulitsidwa pafilimu ya thovu. Ndikoyenera kudziwa kuti kuthamanga kwamadzi otulutsa thobvu si kugwedezeka kwa yankho, koma kugwedezeka kwapamwamba kwa njira yotulutsa thobvu.
3. Mulingo wina wa kuyanjana ndi madzi ochita thobvu. Popeza njira yochotsera thovu kwenikweni ndi mpikisano pakati pa liwiro la kugwa kwa thovu ndi liwiro la kutulutsa thovu, chotsitsacho chimayenera kufalikira mwachangu mumadzi otulutsa thovu kuti chizitha kuchitapo kanthu mwachangu pamitundu yambiri yamadzi othovu. Kupangitsa kuti defoamer ifalikire mwachangu, zinthu zogwira ntchito za defoamer ziyenera kukhala ndi gawo lina la kuyanjana ndi madzi otulutsa thovu. Ngati zosakaniza zogwira ntchito za defoamer zili pafupi kwambiri ndi madzi otsekemera, zidzasungunuka; ngati ali patali, adzakhala ovuta kuwabalalitsa. Pokhapokha pamene kuyanjana kuli koyenera, zotsatira zake zidzakhala zabwino.
4. Palibe mankhwala amadzimadzi ochita thobvu. Defoamer imakhudzidwa ndi madzi ochita thobvu. Kumbali imodzi, defoamer idzataya mphamvu yake, ndipo kumbali ina, zinthu zovulaza zikhoza kupangidwa, zomwe zimakhudza kukula kwa tizilombo toyambitsa matenda.
5. Kusakhazikika kochepa komanso nthawi yayitali yochitapo kanthu. Choyamba, dziwani njira yomwe defoamer iyenera kugwiritsidwa ntchito, kaya ndi madzi kapena mafuta. Mwachitsanzo, mu makampani fermentation, mafuta opangidwa defoamers mongaSilicone yosinthidwa poliyesi kapena polyether iyenera kugwiritsidwa ntchito. Makampani opanga zokutira m'madzi akuyenera kugwiritsa ntchito zida zothira madzi ndi silicone defoamers. Sankhani defoamer, yerekezerani kuchuluka kwake, ndipo tchulani mtengo kuti mupeze chinthu choyenera komanso chotsika mtengo cha defoamer.
Chodzikanira: Zida zina papulatifomu zimachokera pa intaneti kapena zoperekedwa ndi mabizinesi. Sitilowerera ndale ku malingaliro omwe ali m'nkhaniyi. Nkhaniyi ndi ya maumboni ndi kulankhulana kokha ndipo singagwiritsidwe ntchito pazinthu zamalonda. Ufulu ndi wa wolemba woyamba. Ngati pali kuphwanya kulikonse, chonde titumizireni kuti tichotse. Zikomo chifukwa cha chidwi chanu ndi thandizo lanu!
