Ndeapi Mabasa eSurfactants?

1.Kunyorova chiito (Inodiwa HLB: 7-9)

Kunyorova (Wetting) zvinoreva chiitiko chekuti gasi rinoshambadzirwa panzvimbo yakasimba rinotsiviwa nemvura. Mishonga inosimudzira iyi yekutsiviwa kwaniso inonzi wetting agents.Wetting inowanzokamurwa kuva mhando nhatu: contact wetting (adhesion wetting), kunyudza wetting (penetration wetting), and spreading wetting (spreading).

Pakati peizvi, kupararira ndiyo yepamusoro-soro yekunyorova, uye iyo inopararira coefficient inowanzoshandiswa sechiratidzo chekunyorova kwekuita pakati pezvirongwa.

Uye zvakare, iyo yekubata kona ndiyo zvakare chiyero chekuongorora kunyorova kushanda.

Iko kushandiswa kwema surfactants kunogona kudzora dhigirii rekunyorova pakati pezvinwiwa uye zvakaoma.

Muindasitiri yemishonga yezvipembenene, mamwe magranules nehupfu zvekupfapfaidza zvine huwandu hwezvinogadzirwa. Chinangwa chavo ndechekuvandudza kunamatira uye kuiswa kwemumiririri panzvimbo yakarapwa, kuwedzera chiyero chekusunungurwa uye kupararira nzvimbo yezvinoshandiswa zvinoshandiswa pasi pemamiriro emvura, nekuvandudza kudzivirira nekugadzirisa zvirwere.

Muindasitiri yezvizorwa, senge emulsifier, chinhu chakakosha muzvigadzirwa zvekuchengetedza ganda senge makirimu, lotions, anochenesa, uye anobvisa makeup.

2.Foaming uye defoaming zviito

Masurfactants anoshandiswawo zvakanyanya muindasitiri yemishonga. Mukugadzirwa kwemishonga, mishonga yakawanda isinganyungudika yakadai semafuta anonyungudika, mafuta-anonyungudika selulosi, uye mahomoni esteroidal anogona kugadzira mhinduro dzakajeka uye kuwedzera kutarisisa kuburikidza nekuita kwesolubilizing yeva surfactants.

Panguva yekugadzirira mishonga, ma surfactants anokosha se emulsifiers, wetting agents, suspending agents, foaming agents, uye defoaming agents. Furo rine gasi rakavharwa nefirimu rakatetepa remvura. Mamwe ma surfactants anogona kugadzira mafirimu erimwe simba nemvura, anovhara mweya kugadzira furo, iro rinoshandiswa muminerari flotation, furo kudzima moto, uye kuchenesa. Vamiririri vakadaro vanonzi vamiririri vanoita furo.

Dzimwe nguva defoamers inodiwa. Mukugadzirisa shuga uye kugadzirwa kwemishonga yechinyakare yeChinese, furo rakawandisa rinogona kunetsa. Kuwedzera ma surfactants akakodzera kunoderedza simba remufirimu, kunobvisa mabhubhu, uye kunodzivirira tsaona.

3.Kumisa chiito (Suspension stabilization)

Muindasitiri yemishonga yezvipembenene, mapoda anonyorova, emulsifiable concentrates, uye concentrated emulsions zvese zvinoda mamwe ma surfactants.Sezvo zvinhu zvakawanda zvinoshanda mupoda inonyorova zviri hydrophobic organic compounds, ma surfactants anodiwa kuderedza kushushikana kwemvura, zvichiita kuti kunyorova kwezvikamu zvezvinodhaka uye kuumbwa kweaqueous aqueous.

Masurfactants anoshandiswa mumamineral flotation kuti awane kumiswa kudzikamiswa. Nekubvongodza nekutubwida mhepo kubva pasi petangi, mabubbles akatakura chicherwa chehupfu chinoshanda chinoungana pamusoro, apo anounganidzwa uye anobviswa furo kuitira kutarisisa, achiwana enrichment.Jecha, madhaka, nematombo asina zvicherwa zvinoramba zviri pasi uye zvinobviswa nguva nenguva.

Kana 5% yemamineral sand surface yakavharwa nemuunganidzi, inova hydrophobic uye inonamatira kune mabhubhu, ichikwira kumusoro kuti iunganidzwe.Muunganidzi akakodzera anosarudzwa saka mapoka ayo e hydrophilic anonamatira chete kune mineral sand surface apo mapoka e hydrophobic anotarisana nemvura.

4.Disinfection uye sterilization

Muindasitiri yemishonga, ma surfactants anogona kushandiswa semabhakitiriya uye disinfectants. Kuuraya utachiona uye sterilization mhedzisiro inokonzerwa nekudyidzana kwakasimba nebhakitiriya biofilm mapuroteni, zvichikonzera denaturation kana kurasikirwa kwebasa.

Aya ma disinfectants ane yakanyanya solubility mumvura uye anogona kushandiswa kwakasiyana-siyana kune:

·Pre-surgery skin disinfection

·Muronda kana mucosal disinfection

·Kuvharirwa kwezviridzwa

·Kuuraya utachiona hwezvakatipoteredza

5.Detergency uye kuchenesa chiito

Kubvisa mavara egirisi inzira yakaoma ine chekuita neambotaurwa kunyorova, kupupa furo, uye zvimwe zviito.

Detergents kazhinji ine akawanda ebetsero zvikamu ku:

•Kurudzira kunyorova kwechinhu chiri kucheneswa

·Gadzira furo

·Ipa zvinovhenekera mhedzisiro

·Dzivisa kuiswazve kwetsvina

·Maitirwo ekuchenesa kwemasurfactants sechinhu chikuru chinoshanda sezvizvi:

Mvura ine tension yakakwira pamusoro uye kusakwanisa kunyorova kwemavara ane mafuta, zvichiita kuti zviome kubvisa. Mushure mekuwedzera ma surfactants, mapoka avo e hydrophobic anonangana kunzvimbo dzemachira uye netsvina yakashambadza, zvishoma nezvishoma kubvisa zvinosvibisa. Tsvina inoramba yakaturikwa mumvura kana kuti inoyangarara pamusoro nefuro isati yabviswa, nepo nzvimbo yakachena ichiputirwa nema surfactant molecules.

Chekupedzisira, zvinofanirwa kucherechedzwa kuti ma surfactants haashande kuburikidza nemuchina mumwe chete asi kazhinji kuburikidza neakasanganiswa maitiro ezvakawanda zvinhu.

Semuenzaniso, muindasitiri yemapepa, vanogona kushanda se:

·Vashandi vekubikira

·Waste paper de-inking agents

·Sizing agents

·Resin zvipingamupinyi control agents

·Defoamers

·Manyoro

·Antistatic agents

·Scale inhibitors

·Softening agents

·Degreasing agents

·Mishonga yemabhakitiriya uye algaecides

·Corrosion inhibitors
