Kushandiswa kweSurfactants muFeterezari
Kudzivirira keke yefetereza: Nekuvandudzwa kweindasitiri yefetereza, kuwedzera mazinga efetiraiza, uye nekukura kuziva kwezvakatipoteredza, nzanga yakaisa zvichemo zvakakwirira pamaitirwo ekugadzirwa kwefetereza uye kuita kwechigadzirwa. Kushandiswa kwesurfactantsinogona kuwedzera kunaka kwefetereza. Kubika kwave kunetsa kuindasitiri yefetereza, kunyanya yeammonium bicarbonate, ammonium sulfate, ammonium nitrate, ammonium phosphate, urea, uye mafetireza ekomboni. Kuti udzivise kukaka, kuwedzera kune matanho ekudzivirira panguva yekugadzira, kurongedza, uye kuchengetedza, ma surfactants anogona kuwedzerwa kune fetiraiza.
Urea inowanzoita keke panguva yekufambisa uye kuchengetedza, zvichikanganisa zvakanyanya kutengesa kwayo uye kushandiswa kwayo. Ichi chiitiko chinoitika nekuda kwerecrystallization pamusoro peiyo urea granules. Hunyoro huri mukati megranules hunoenda kumusoro (kana hunotora hunyoro hwemumhepo), huchiita mvura yakatetepa. Kana tembiricha ichichinja, mwando uhwu unobuda, zvichiita kuti mhinduro yakazara pamusoro iite crystal uye ichitungamira mukukaka.
MuChina, mafetiraiza enitrogen anowanikwa mumhando nhatu: ammonium nitrogen, nitrate nitrogen, uye amide nitrogen. Fetereza yeNitro ifetireza yakakwira-concentration compound ine zvese ammonium nenitrate nitrogen. Kusiyana neurea, nitrate nitrogen mufotereza yenitro inogona kutorwa zvakananga nezvirimwa pasina kupinduka kwechipiri, zvichikonzera kushanda kwepamusoro. Mafetereza eNitro akakodzera zvirimwa zvemari zvakaita sefodya, chibage, mavise, michero, miriwo nemiti yemichero, zvichiita zvirinani pane urea muvhu realkaline nematunhu ekarst. Nekudaro, sezvo nitro compound mafetiraiza anonyanya kuve neammonium nitrate, iyo yakanyanya hygroscopic uye inosangana nekristaro chikamu shanduko nekushanduka kwetembiricha, ivo vanowanzoita caking.
Kushandiswa kweSurfactants mune Yakasvibiswa Soil Remediation
Nekuvandudzwa kwemaindasitiri akadai se petrochemicals, mishonga yemishonga, uye mapurasitiki, akasiyana hydrophobic organic zvinosvibisa (semuenzaniso, petroleum hydrocarbons, halogenated organics, polycyclic inonhuwira hydrocarbons, mishonga yekuuraya zvipembenene) uye inorema simbi ions inopinda muvhu kuburikidza nekuteuka, kudonha, kusvibiswa kwakanyanya, uye kukonzeresa. Hydrophobic organic pollutants inosunga nyore nyore nevhu organic zvinhu, kuderedza bioavailability yavo uye kutadzisa ivhu kushandiswa.
Masurfactants, ari amphiphilic molecules, anoratidza hukama hwakasimba hwemafuta, anonhuwirira hydrocarbons, uye halogenated organics, zvichiita kuti zvishande mukugadzirisa ivhu.
Kushandiswa kwevaSurfactants muKuchengetedza Mvura Yekurima
Kusanaya kwemvura inyaya yepasi rose, nekurasikirwa kwegoho nekuda kwekusanaya kwemvura zvakaenzana nekurasikirwa kwakasanganiswa kubva kune dzimwe njodzi dzemamiriro ekunze. Maitiro ekudzvinyirira evaporation anosanganisira kuwedzera ma surfactants kune masisitimu anoda kuchengetedza mwando (semuenzaniso, mvura yekurima, nzvimbo dzechirimwa), kugadzira insoluble monomolecular firimu pamusoro. Iyi firimu inotora nzvimbo shoma yekubuda, ichidzikisa inoshanda evaporative nzvimbo uye kuchengetedza mvura.
Kana yakapfapfaidzwa panzvimbo yechirimwa, ma surfactants anoumba chimiro chakanangana: yavo hydrophobic migumo (yakatarisana nechirimwa) inodzosera uye inovharira mukati manyoro evaporation, nepo mhedziso yavo yehydrophilic (yakatarisana nemhepo) inogonesa kunyorova kwemhepo. Izvo zvakasanganiswa zvinodzivirira kurasikirwa kwemvura, zvinowedzera kusanaya kwezvirimwa, uye zvinowedzera goho.
Mhedziso
Muchidimbu, ma surfactants ane mashandisiro akafara muhunyanzvi hwemazuva ano hwekurima. Sezvo hunyanzvi hutsva hwekurima hunobuda uye matambudziko matsva ekusvibisa anomuka, kudiwa kwetsvakiridzo yepamberi nekusimudzira kuchakura. Chete nekugadzira ma-surfactants anoenderana nendima iyi tinogona kusimudzira kuzadzikiswa kwezvekurima zvechizvino-zvino muChina.
