Scale inhibitor

Scale inhibitor: inogona kuparadzira isinganyungudika inorganic munyu mumvura, kudzivirira kana kukanganisa kunaya uye kuyera kwekusanyungudika inorganic munyu pamusoro pesimbi, uye kuchengetedza yakanaka yekupisa mhedzisiro yemidziyo yesimbi. Iyo yakagadzirwa inogadzirirwa nekutora epoxy resin uye chaiyo amino resin sezvigadziko, ichiwedzera huwandu hwakakodzera hweakasiyana anti rust uye anti-corrosion additives kuumba chinhu chimwe chete. Iyo ine yakanakisa kudzivirira, kusamira, ngura kuramba, yakanaka chiyero kuramba, kupisa conductivity, kupikisa kwakanyanya kune isina simba acid, yakasimba alkali, organic solvents uye zvimwe zvivakwa, yakasimba adhesion, inopenya, inochinjika, compact uye yakaoma pendi firimu.

Folding editing mechanism

Kubva pamaitiro escale inhibitor, chiyero chekuvharisa che scale inhibitor chinogona kukamurwa kuita chelation, dispersion uye lattice distortion. Muyedzo yekuongorora marabhoritari, kupararira ndiwo mushonga wekubatanidza mhedzisiro, uye lattice kukanganisa maitiro ndiwo mushonga wekuparadzira maitiro.

Maitiro ekushanda epamusoro-soro reverse osmosis scale inhibitor

Hazvidikanwi kuwedzera mamwe asidi, iyo inogona kunyatsodzivirira kuparara kwemidziyo nezvinhu zvine acidic.

2 chelating effect yakagadzikana, inogona kudzivirira iron, manganese uye mamwe maion simbi pane membrane tube kuti iite tsvina.

Inokodzera marudzi ese e membrane tube zvinhu.

Iyo yakanyanya hupfumi chiyero inhibition control inogona kuwanikwa neine dosi shoma uye yakaderera mutengo.

Inogona kuderedza kucheneswa kwe membrane uye kuwedzera hupenyu hwesevhisi ye membrane.

Kupeta chelation

Chelation chirongwa umo iyo yepakati ion inosunga kune maviri kana anopfuura maatomu ekubatanidza eiyo yakafanana polydentate ligand. Somugumisiro we chelation, scaling cations (yakadai seCa2 +, Mg2 +) inopindirana ne chelating agents kuti iite chelates yakagadzikana, iyo inovadzivirira kubva pakusangana neanosimudza anions (akadai CO32 -, SO42 -, PO43 - uye sio32 -), nokudaro zvichideredza zvakanyanya mukana wekuyera. Chelation is stoichiometric, semuenzaniso, kusungwa kwe EDTA molecule kune divalent metal ion.

Iko chelating simba ye chelating agents inogona kuratidzwa ne chelating kukosha kwe calcium. Kazhinji, mishonga yemishonga yemvura yekutengeserana (chikamu chechikamu chezvikamu zvinotevera zvinoshanda zvose 50%, zvakaverengwa neCaCO3): aminotrimethylphosphonic acid (ATMP) - 300mg / g; diethylenetriamine pentamethylene phosphonic acid (dtpmp) - 450mg / g; ethylenediamine tetraacetic acid (EDTA) - 15om / g; hydroxyethyl diphosphonic acid (HEDP) - 45 OM. Mune mamwe mazwi, 1mg chelating agent inogona chete chelate calcium carbonate scale pasi pe 0.5mg. Kana calcium uye magnesium ions ine kuomarara kwese kwe smm0fl ichida kudzikamiswa muhurongwa hwemvura inotenderera, chelating agent inodiwa ndeye 1000m / L, iyo ine hupfumi uye inoshanda. Naizvozvo, mupiro we scale inhibitor chelation inongova chikamu chiduku. Nekudaro, iyo chelation ye scale inhibitors inoita basa rakakosha mumvura yepakati uye yakaderera.

Kupeta kupararira

Mhedzisiro yekupararira ndeyekudzivirira kubata uye kuunganidzwa kweokisisa zvidimbu zvimedu, nekudaro kudzivirira kukura kweiyo oxide scale. Zvimedu zvekuyera zvinogona kuva calcium uye magnesium ions, mazana eCaCO3 neMgCO3 mamorekuru, guruva, sediment kana zvimwe zvisinganyungudika nemvura. Dispersant ipolymer ine humwe huremu hwemamorekuru (kana dhigirii repolymerization), uye kupararira kwayo kunoenderana zvakanyanya nehuremu hwemamorekuru (kana dhigirii repolymerization). Kana iyo dhigirii yepolymerization yakanyanya kuderera, nhamba yezvikamu zvakashambadzirwa uye zvakaparadzirwa idiki, uye kuparadzira kushanda kwakaderera; kana dhigirii repolymerization rakanyanyisa, nhamba yezvikamu zvakashambadzirwa uye zvakaparadzirwa zvakawandisa, mvura inenge iine turbid uye kunyange kuita flocs (panguva ino, maitiro ayo akafanana neaya flocculant). Kuenzaniswa ne chelating nzira, kupararira kunoshanda. Mhedzisiro yacho inoratidza kuti 1 mg dispersant inogona kuita 10-100 mg scale particles zviripo zvakagadzikana mumvura inotenderera. Mumvura yakaoma uye yepakati nepakati, dispersion of scale inhibitor inoita basa rakakosha.

Yakapetwa latisi kukanganisa

Kana kuoma uye alkalinity yegadziriro yakakwira, uye chelating agent uye dispersant hazvina kukwana kudzivirira kunaya kwavo kwakazara, ivo vanozongodonha. Kana pasina chikero chakasimba pamusoro pechitsinhanisi chekupisa, chiyero chichakura pamusoro pechitsinhanho chekupisa. Kana paine zvakakwana dispersant, tsvina particles (inoumbwa nemazana e calcium carbonate molecules) inotorwa.
