Nekuda kwehuwandu hushoma hweVOC mumapendi emvura, ari kuramba achizivikanwa nevatengi. Zvisinei, kune mamwe mapendi emvura, tichaona kuti kana akasagadziriswa nenguva, zviri nyore kugadzira maburi emabubble uye maziso ehove, asi mamwe haazogadziriswi. Chii chiri chakavanzika pakati? Mhinduro yacho ndeye kana paine kana pasina kuwedzera mvura-based coating defoamer.

Ndezvipi zvinowedzera zvinosanganisirwa muzvipfeko zvemvura
Mapendi emvura anonyanya kugadzirwa nemvura semushonga, uye zvimwe zvinhu zvakasiyana-siyana zvinowedzerwa mukugadzirwa kwacho, zvakaita se: mushonga wekuomesa, mushonga unodzivirira kukora, mushonga wefungi, mushonga wekubatanidza kukora, mushonga wekukora, nezvimwewo, kusimbisa mashandiro emapendi emvura.

Sei pendi inobva mumvura ichibuda mapombi
Kubva pane zvakawedzerwa zviri pamusoro apa tinogona kuona kuti zvizhinji zvezvinowedzera zviri muzviputiro zvemvura ndezvema surfactants.

izvo zvinogona kukonzera kuumbwa kwefuro zviri nyore. Kunyanya mukusanganisa muchina wekugadzira machira, zviri nyore kugadzira furo rakawanda, uye zvakaoma kubvisa. Musiyano uripo pakati pekuti zvimwe zvacho zvinobuda furo here kana kuti zvimwe zvacho hazvibudi furo uri pakuti defoamer yekudzivirira furo inobva mumvura inowedzerwa here kana kuti kwete.

Mushonga wekubvisa furo unobva mumvura unogona kunangana nedambudziko refuro rinobuda mumvura, pane mhedzisiro yakanaka yekubvisa furo uye kudzivirira furo, kune dambudziko refuro rinobuda mumvura, musataura nezvazvo. Saka, mamwe mafuro anobva mumvura haaputi nekuti ane mushonga wekubvisa furo unobva mumvura.

Kuwedzera pendi inobvisa pendi kubva mumvura kunofanana nekuwedzera kunaka kwependi. Inobatsira zvikuru pakupeta pendi kubva mumvura.

Mabhenefiti ekushandisa defoamer inogadzirwa nemvura
Muchina wekubvisa machira unobva mumvura unogadzirwa nepolyether ester yeorganic sechikamu chikuru uchishandisa nzira yakakosha.

Zvakanakira zvinosanganisira: emulsification yakanaka, kupararira kwakasimba, kukurumidza kubvisa furo uye kudzivirira furo. Kana paine dambudziko remachira emvura, furo harizokanganisi sisitimu, harisi nyore kupukuta mafuta akapwanyika. Zviri nyore kushandisa. Vagadziri vemanyuko, mashandiro anodhura zvakanyanya, uye mutengo wakanakira.
