Oiri negasi zvinhu zvakakosha pahupfumi hwenyika, zvinopa simba pakufambisa, zvinodziisa dzimba, uye zvinopa simba kumaindasitiri. Zvisinei, zvinhu izvi zvinokosha zvinowanzowanikwa mumisanganiswa yakaoma inogona kusanganisira mvura nezvimwe zvinhu. Kuparadzanisa zvinwiwa izvi kubva kugasi nemafuta zvinokosha kunodiwa kuti zvicheneswe uye zvishandiswe. Maitiro ekuparadzanisa aya anogona kuva akaoma, kazhinji zvichikonzera kuumbwa kwe emulsions dzakaoma kuputsa. Shandisa basa re demulsifiers mukugadzirisa mafuta negasi.
Zvidzikisiramakemikari akakosha anowedzerwa mumusanganiswa wemafuta negasi kuti abatsire kuputsa emulsions, zvichiita kuti nzira yekuparadzanisa ive nyore. Zvinhu izvi zvinosangana nesurfactants iri mu emulsion, zvichikanganisa kugadzikana kwazvo, zvichiita kuti zvikamu zvemafuta nemvura zviparadzane zviri nyore.
Kukosha kwezvinobvisa musuliMukugadzirisa mafuta negasi hazvigone kutaurwa zvakanyanya. Zvinobatsira kuvandudza kushanda zvakanaka kwemaitiro ekuparadzanisa, zvichideredza huwandu hwesimba rinodiwa pakuchenesa. Zvinodzivirirawo kuungana kwemapaipi nemidziyo yekugadzirisa, zvichiita kuti zvishande zvakanaka uye kuwedzera hupenyu hwenzvimbo idzi.
Kusarudzwa kwe demulsifier chaiyo kwakakosha, sezvo makemikari akasiyana achishanda zvakanaka mumamiriro ezvinhu akasiyana uye nemhando dzakasiyana dze emulsions. Ma processor anofanirwa kufunga nezvezvinhu zvakaita se pH level, tembiricha, uye rudzi rwemafuta kana gasi riri kugadziriswa pakusarudza demulsifier yakanakira mashandiro avo.
Mukupedzisa, ma demulsifiers zvinhu zvakakosha mukugadzirisa mafuta negasi, zvichiputsa ma emulsions akaomarara uye zvichiita kuti zviwanikwa zvinokosha zviparadzaniswe. Kusarudza demulsifier nemazvo kunogona kuvandudza mashandiro, kuderedza mitengo, uye kuwedzera hupenyu hwemichina, zvichiita kuti ive chishandiso chinokosha muindasitiri yemafuta negasi yanhasi.
Ndeapi Mhando dzakasiyana dzeDemulsifiers?
Ma demulsifier anouya nenzira dzakasiyana-siyana zvichienderana nechimiro chemakemikari uye mashandiro awo. Heano mamwe marudzi akajairika:
Zvidziviriri Zvisiri zveionic
Zvisiri zveionic demulsifiers ma surfactants asingaite ioni mumushonga. Zvinhu izvi zvinowanzova nemapoka e polar anosangana nema surfactants mu emulsions kuti asagadzikana. Anoshanda muhurongwa hwemvura husina munyu wakawanda uye husina mvura yakawanda uye anogona kushandiswa mumhando dzakasiyana-siyana.
Zvidziviriro zveIonic
Zvidziviriro zveIonic zvinhu zvinogadzira ma "surfactants" zvinoumba "ioni" mu "solution", zvichigadzira ma "positive" kana "negative" ayo anosangana nema "surfactants" anochajwa zvakasiyana mu "emulsions". Zvinhu izvi zvinowanzo shandiswa mu "water-salt" systems dzemvura uye zvinogona kushanda mukuputsa "water-in-oil emulsification".
Zvidziviriro zveCationic
Ma "cationic demulsifiers" ma "positive charge" anosanganisa ma "negative charge" muma "emulsions" kuti asagare zvakanaka. Zvinhu izvi zvinoshanda mukupwanya ma "water-in-oil emulsions" uye zvinogona kushandiswa muma "high salinity systems". Anoorawo, zvichiita kuti asakuvadze nharaunda.
Zvidziviriri zveAnionic
MaAnionic demulsifiers ma surfactants ane charge yakaipa anosangana nema surfactants ane charge yakanaka mu emulsions kuti asagare zvakanaka. Zvinhu izvi zvinoshanda mukupwanya ma emulsions ane mafuta mumvura uye zvinogona kushandiswa muma system asina munyu wakawanda. Anoorawo, zvichiita kuti asakuvare nharaunda.
Mukupedzisa, ma demulsifier anouya nenzira dzakasiyana zvichienderana nechimiro chemakemikari avo uye basa ravo rekuputsa ma emulsion zvinobudirira mukugadzirisa mafuta negasi. Kusarudzwa kwemhando chaiyo ye demulsifier kwakakosha kuti pave nemhedzisiro yakanaka yekuparadzanisa uku tichifunga nezvezvinhu zvakatipoteredza uye kushanda zvakanaka kwemari.
