Defoamers mu Industrial Applications

Zosokonezandizofunikira pakugwiritsa ntchito mafakitale. Njira zambiri zamafakitale zimatulutsa thovu, kaya ndi mukubwadamuka wamakina kapena zochita zamankhwala. Ngati sichilamuliridwa ndikuthandizidwa, imatha kuyambitsa mavuto akulu.

Chithovu aumbike chifukwa kukhalapo kwa surfactant mankhwala mu dongosolo madzi, amene kukhazikika thovu, chifukwa chithovu mapangidwe. Ntchito ya ma defoamers ndikulowa m'malo mwa mankhwala ophatikizikawa, zomwe zimapangitsa kuti thovulo liphulike ndikuchepetsa thovu.

Mitundu yayikulu ya thovu ndi iti?

Biofoam ndi surfactant thovu:

Biofoam imapangidwa ndi tizilombo tating'onoting'ono tating'onoting'ono tikamaphwanya ndikuwola zinthu zamoyo m'madzi oipa. Biofoam imakhala ndi tinthu ting'onoting'ono tozungulira, tokhazikika kwambiri, ndipo imawoneka youma.

Chithovu cha surfactant chimayamba chifukwa chowonjezera zinthu monga sopo ndi zotsukira, kapena chifukwa cha zomwe zikuwononga ndi mafuta kapena mafuta ndi mankhwala ena.

Kodi defoamers amagwira ntchito bwanji?

Ma defoamers amalepheretsa kupanga chithovu posintha mawonekedwe amadzimadzi. Ma defoam amalowa m'malo mwa mamolekyu a surfactant mu gawo lopyapyala la thovu, zomwe zikutanthauza kuti choyikapo chitha kukhala chotanuka komanso chothyoka.

Kodi kusankha defoamer?

Ma defoam nthawi zambiri amagawika kukhala ma silicon-based defoamers komanso osapanga silicone. Kusankhidwa kwa defoamer kumatengera zofunikira ndi zikhalidwe za pulogalamuyo. Ma silicon-based defoamers amagwira ntchito pansi pa pH ndi kutentha kosiyanasiyana ndipo nthawi zambiri amawakonda chifukwa chokhazikika komanso kuchita bwino. Ma defoam osakhala ndi silicone ndi ochotsera mafoam opangidwa makamaka ndi zinthu zachilengedwe monga ma amide amafuta, sopo zachitsulo, mowa wamafuta, ndi mafuta acid esters. Ubwino wa machitidwe osakhala a silicone ndi ma coefficients akuluakulu ophatikizika ndi kuthekera kolimba kwa thovu; Choyipa chachikulu ndichakuti kuthekera kochotsa thovu kumakhala kocheperako pang'ono chifukwa champhamvu kwambiri kuposa silikoni.

Posankha defoamer yoyenera, zinthu monga mtundu wamakina, mawonekedwe ogwiritsira ntchito (kutentha, pH, kupanikizika), kuyanjana kwamankhwala, ndi zofunikira zowongolera ziyenera kuganiziridwa. Posankha defoamer yoyenera, makampaniwa amatha kuthana ndi mavuto okhudzana ndi thovu ndikuwongolera magwiridwe antchito.

Ndi nthawi iti pamene chowonjezera chotsitsa madzi chimafunika pochiza madzi?

Panthawi yoyeretsa madzi, nthawi zambiri pamakhala zinthu zomwe zimapangitsa kuti pakhale thovu, monga kugwedezeka kwa madzi, kutulutsa mpweya wosungunuka, kukhalapo kwa zotsukira ndi mankhwala ena.

M'makina ochizira madzi oyipa, thovu limatha kutseka zida, kuchepetsa magwiridwe antchito, komanso kusokoneza madzi oyeretsedwa. Kuonjezera ma defoams m'madzi kungathe kuchepetsa kapena kulepheretsa kupanga chithovu, zomwe zimathandiza kuti mankhwalawa asamayende bwino komanso kuti madzi azikhala bwino.

Ma defoam kapena antifoam agents ndi mankhwala omwe amawongolera ndipo, ngati kuli kofunikira, amachotsa thovu m'madzi oyeretsedwa kuti apewe zotsatira zoyipa za kuchita thovu pamlingo wosayenera kapena mopitilira muyeso.

Ma defoamers athu atha kugwiritsidwa ntchito m'malo otsatirawa:

● Makampani opanga mapepala ndi mapepala

● Kuyeretsa madzi

● Makampani otsukira

● Makampani opanga utoto ndi zokutira

● Makampani opanga mafuta

● Ndi mafakitale ena
