Sei uchifanira kusarudza low-foam surfactant?

Paunenge uchisarudza ma surfactants ako ekuchenesa mafomati kana kugadzirisa maapplication, furo chinhu chakakosha hunhu. Semuyenzaniso, mumanyorero akaomarara-pamusoro pekuchenesa maapplication-akadai sezvigadzirwa zvekuchengetedza mota kana kugeza-wacha dhishi-mafuro akawandisa anowanzo hunhu hunodiwa. Izvi zvinodaro nekuti kuvepo kwefuro rakagadzikana zvakanyanya kunoratidza kuti iyo surfactant yakabatiswa uye kuita basa rayo rekuchenesa. Sezvineiwo, kune akawanda maindasitiri ekuchenesa uye kugadzirisa maapplication, furo rinogona kukanganisa mamwe ma mechanika ekuchenesa zviito uye kumisa kuita kwese. Muzviitiko izvi, vanogadzira vanofanirwa kushandisa yakaderera-foam surfactants kuendesa yaunoda yekuchenesa kuita uku uchidzora furo kusungwa. Ichi chinyorwa chine chinangwa chekuunza yakaderera-foam surfactants, ichipa pekutangira yekusarudza surfactant mune yakaderera-furo yekuchenesa maapplication.

Low-Foam Applications
Foam inogadzirwa nekusuduruka pamhepo-yepamusoro interface. Naizvozvo, kuchenesa zviito zvinosanganisira kubvongodza kukuru, kusanganiswa kweshear yakakura, kana kupfapfaidza michina kazhinji kunoda ma surfactants ane furo rakakodzera. Mienzaniso inosanganisira: kugeza maparts, CIP (clean-in-place) kuchenesa, mechanical floor scrubbing, maindasitiri nekutengesa mbatya, zvinwiwa zvesimbi, dishwasher dishwashing, kuchenesa chikafu nechinwiwa, nezvimwe.

Kuongororwa kweLow-Foam Surfactants
Kusarudzwa kwemasurfactants - kana musanganiswa wevanoshandisa surfactants - yekudzora furo kunotanga nekuongorora kuyerwa kwefuro. Kuyera kwefuro kunopihwa nevagadziri vepamusoro mune yavo tekinoroji chigadzirwa zvinyorwa. Kune kuyerwa kwefuro kwakavimbika, datasets inofanirwa kuve yakavakirwa pane inozivikanwa foam test standard.

Iwo maviri akajairika uye akavimbika furo bvunzo ndeye Ross-Miles foam bvunzo uye yakakwirira-shear furo bvunzo.
•Ross-Miles Foam Test , inoongorora kugadzirwa kwefuro kwekutanga (flash foam) uye kugadzikana kwefuro pasi pekusagadzikana kwemvura. Muedzo unogona kusanganisira kuverenga kwekutanga furo level, inoteverwa nefoam level mushure memaminitsi maviri. Inogona zvakare kuitwa pane akasiyana surfactant concentration (semuenzaniso, 0.1% uye 1%) uye pH mazinga. Mazhinji mafomati ari kutsvaga yakaderera-furo kudzora anotarisa pane yekutanga furo kuyerwa.
•High-Shear Test (ona ASTM D3519-88).
Muedzo uyu unofananidza kuyerwa kwefuro pasi pevhu uye isina kusvibiswa mamiriro. Iyo yepamusoro-yekugera bvunzo zvakare inofananidza iyo yekutanga furo kureba nehurefu hwefuro mushure memaminitsi mashanu.

Zvichienderana nechero ipi yeidzi nzira dzekuyedza dziri pamusoro, akati wandei pamusika vanosangana nematanho ekudzikisa-furo zvigadzirwa. Nekudaro, zvisinei nekuti furo bvunzo nzira yakasarudzwa, yakaderera-furo surfactants inofanirawo kuve nezvimwe zvakakosha zvemuviri nekuita zvimiro. Zvichienderana nekushandiswa uye nzvimbo yekuchenesa, mamwe maitiro akakosha ekusarudza surfactant anogona kusanganisira:
•Kuchenesa kuita
• Zvakatipoteredza, hutano, uye kuchengetedzwa (EHS)
•Ivhu rekuburitsa zvinhu
•Kutembiricha kwakakura (kureva, mamwe mafevha epasi-furo anoshanda chete pakupisa kwakanyanya)​
•Kureruka kwekugadzira uye kuenderana nezvimwe zvinongedzo
•Kugadzikana kwePeroxide
Kune vanogadzira, kuenzanisa zvivakwa izvi nedhigirii inodiwa yekudzora furo mukushandisa kwakakosha. Kuti uwane chiyero ichi, zvinowanzodikanwa kubatanidza ma surfactants akasiyana kuti agadzirise ese ari furo uye kuita zvinodiwa-kana kusarudza yakaderera-kupakati-yepakati-mafuro surfactants ane hupamhi hwekushanda.
