Kushandiswa kweSurfactants muFetiraiza
Kudzivirira kuchengetwa kwemafetiraiza: Nekukura kweindasitiri yemafetiraiza, kuwedzera kwehuwandu hwefetiraiza, uye kuwedzera kweruzivo rwezvakatipoteredza, nzanga yakawedzera kudiwa kwemaitiro ekugadzira feteraiza uye mashandiro ezvigadzirwa.zvinhu zvinoshandisa masurfactantkunogona kuwedzera kunaka kwefetereza. Kubika keke kwave kuri dambudziko kwenguva refu kuindasitiri yefetereza, kunyanya yeammonium bicarbonate, ammonium sulfate, ammonium nitrate, ammonium phosphate, urea, uye mafetiraiza akasanganiswa. Kudzivirira kubikwa keke, kuwedzera pamatanho ekudzivirira panguva yekugadzira, kurongedza, uye kuchengetwa, masurfactants anogona kuwedzerwa kufetiraiza.
Urea inowanzoita makeke panguva yekutakura nekuchengetera, zvichikanganisa zvakanyanya kutengeswa kwayo uye kushandiswa kwayo. Izvi zvinoitika nekuda kwekudzokororwa kwecrystallization pamusoro pemagranule eurea. Hunyoro huri mukati memagranule hunoenda pamusoro (kana kunwisa hunyoro hwemhepo), huchiumba denderedzwa remvura. Kana tembiricha dzichichinja-chinja, hunyoro uhwu hunopera, zvichiita kuti mvura yakasviba pamusoro payo iite crystallize uye zvichikonzera kuchekwa.
MuChina, mafetiraiza enitrogen anowanikwa mumhando nhatu: ammonium nitrogen, nitrate nitrogen, uye amide nitrogen. Nitro fertilizer imhando yepamusoro ine ammonium ne nitrate nitrogen. Kusiyana neurea, nitrate nitrogen mu nitro fertilizer inogona kutorwa zvakananga nezvirimwa pasina kushandurwa kwechipiri, zvichikonzera kushanda kwakanyanya. Nitro fertilizer yakakodzera zvirimwa zvekutengesa zvakaita sefodya, chibage, manwiwa, michero, miriwo, nemiti yemichero, zvichiita zviri nani pane urea muvhu realkaline nenzvimbo dzekarst. Zvisinei, sezvo nitro fertilizer inonyanya kuve neammonium nitrate, iyo ine hygroscopic yakawanda uye inochinja-chinja tembiricha, inowanzo bikwa.
Kushandiswa kweSurfactants mukugadzirisa ivhu rakasvibiswa
Nekukura kwemaindasitiri akadai semakemikari epetrochemicals, mishonga, uye mapurasitiki, tsvina dzakasiyana-siyana dzinosvibisa mvura (semuenzaniso, petroleum hydrocarbons, halogenated organics, polycyclic aromatic hydrocarbons, mishonga yezvipembenene) uye ma heavy metal ions zvinopinda muvhu kuburikidza nekudonha, kudonha, kubuda kwemvura mumaindasitiri, uye kuraswa kwemarara, zvichikonzera kusvibiswa kwakanyanya. Zvinosvibisa mvura zvinosangana nyore nyore nezvinhu zvipenyu zvevhu, zvichideredza kuwanikwa kwazvo uye zvichikanganisa kushandiswa kwevhu.
Ma surfactants, ari mamorekuru anofamba-famba mumvura zhinji, anoratidza hukama hwakasimba nemafuta, mahydrocarbon anonhuhwirira, uye halogenated organics, zvichiita kuti ashande zvakanaka pakugadzirisa ivhu.
Kushandiswa kweSurfactants muKuchengetedza Mvura Yekurima
Kusanaya kwemvura idambudziko repasi rose, nekurasikirwa kwegoho nekuda kwekusanaya kwemvura kunoenderana nekurasikirwa kwakabatana kubva kune dzimwe njodzi dzemamiriro ekunze. Maitiro ekudzora kusvibiswa kwemvura anosanganisira kuwedzera masurfactants kumasystem anoda kuchengetedza hunyoro (semuenzaniso, mvura yekurima, pamusoro pemiti), kugadzira firimu remamorekuru risinganyungudike pamusoro. Firimu iri rinotora nzvimbo shoma yekusvibiswa kwemvura, richideredza nzvimbo inoshanda yekusvibiswa kwemvura uye richichengetedza mvura.
Kana ikapfapfaidzwa pamusoro pemiti, masurfactant anoumba chimiro chakatarisana: magumo ayo asingapindi mvura (akatarisana nemuti) anodzinga uye anovhara kupwanyika kwemvura mukati, nepo magumo ayo asingapindi mvura (akatarisana nemhepo) achibatsira kuti hunyoro husapinda mumhepo. Kubatanidzwa kwacho kunodzivirira kurasikirwa nemvura, kunowedzera kudzivirira kusanaya kwemvura, uye kunowedzera goho.
Mhedziso
Muchidimbu, ma surfactants ane mashandisirwo akawanda muhunyanzvi hwemazuva ano hwekurima. Sezvo nzira itsva dzekurima dzichibuda uye matambudziko matsva ekusvibiswa kwemhepo achimuka, kudiwa kwekutsvaga nekuvandudza ma surfactants epamusoro kuchakura. Kungogadzira ma surfactants anoshanda zvakanaka akagadzirirwa basa iri ndiko chete kunokwanisa kukurumidza kuzadzikiswa kwekuvandudzwa kwekurima muChina.
