Kunyatsojeka pakuyera huwandu hwemvura panguva chaiyo kunokanganisa zvakananga kugadzirwa kwe ethyl acetate uye kushanda zvakanaka kwemaindasitiri.kuputiramhando. Mamita ekudzikisa huwandu hwezvinhu, akadai semachubhu anodzungudza uye ma sensor e cantilever resonance, anoderedza zvikanganiso zvekugadzira, achigadzirisa kuchinja kwehuwandu mumasekonzi. Tsvagiridzo inoratidza kuti ma sensor aya anodzora kubuda kwe ethyl acetate process pamusoro pe95% achishandisa Fischer esterification, zvichideredza acetic acid inoraswa uye ethanol. Kuyerwa kwe inline otomatiki kunochengetedza huwandu hwakagadzikana panguva yekuchinja kwemafambiro emaitiro - reaction, distillation, uye blending - zvichivandudza mashandiro ekuchengetedza zvakatipoteredza emapuranga emvura. Kutevera nguva chaiyo kunodzivirira kusiyana kunotungamira mukutsemuka kwefirimu uye kudonha kwependi. Kubatanidza mamita ekudzikisa huwandu hwezvinhu mukugadzirwa kwe coating kunogonesa kugadziriswa nekukurumidza kwezvikamu zve ingredient kuti pave nekupararira kwakafanana uye emulsification. Zvishandiso zve inline zveLonnmeter zvinoyera huwandu, viscosity, uye tembiricha yekugadzira coating yepamusoro, inochengetedza zvakatipoteredza uchishandisa ethyl acetate, kubvisa kusawirirana kwebatch uye kugadzirisa nhanho yega yega yekugadzira.
Pfupiso yeEthyl Acetate Production Process
Maitiro ekugadzira ethyl acetate anoshandisa Fischer esterification, zvichiwana goho riri pamusoro pe95% nematanho akadzorwa. Dhayagiramu yekufamba kwemaitiro e ethyl acetate inoratidza matanho matatu makuru: reaction, distillation, uye kuchenesa. Munguva ye reaction stage, ethanol inobatana neacetic acid, ichishandisa sulfuric acid sechinhu chinobatsira pasi pemutemo wekupisa nekumanikidzwa nguva dzose.
Kuyerwa kwehuwandu hwemvura mukati memutsara kunobatanidza panzvimbo dzakakosha, kusanganisira mudziyo wekuita, mayuniti ekuparadzanisa, uye matangi ekubatanidza. Zvishandiso zveLonnmeter zvinogonesa kuteererwa kwehuwandu hwemvura panguva chaiyo, kugadzirisa kupatsanurwa kwechikamu uye nzvimbo dzekucheka dzinonyungudutswa. Kuongororwa kwehuwandu hwemvura mukati memutsara pamatanho aya kunodzivirira zvigadzirwa zvisina kutsanangurwa uye kunotsigira kubviswa kwemvura panguva yekuchenesa.
Kudzora huwandu hwehuni zvakanyatsonaka kwakakosha pakugadzira mapuranga anogadzirwa nemvura.Kuenderana kwemvuraZvimiro zvinovimbisa kusimba kwakasimba, zvichideredza zvinokonzera kutsemuka kwefirimu uye kudonha kwependi mumachira ehuni asingakuvadzi nharaunda. Mamita akabatanidzwa e inline density anopa mhinduro nekukurumidza, achikurudzira kufanana uye kushanda kwakavimbika mumatanho ekugadzira machira emaindasitiri.

Kugadzira Mapendi Emaindasitiri uye Mapendi Ehuni Anoshandiswa Nemvura
Mapendi ehuni anogadzirwa nemvura anoshandisa ethyl acetate semushonga mukuru wekugadzira firimu nekukurumidza uye kufanana kwepamusoro. Maitiro ekugadzira ethyl acetate anofanira kupa kuchena kwakanyanya kuti asvike padanho remapendi rinoda kufukidza. Matanho ekusanganisa, kupararira, uye emulsification anoda huwandu hwe solvent hwakadzorwa kudzivirira kuparadzaniswa kwechikamu uye hunhu hwefirimu husingaenderane.
Matanho ekugadzira machira ekugadzira maindasitiri—kusanganisa zvinhu, kusanganisa, kusefa, uye kurongedza—anoda kutariswa kwehuwandu hwezvinhu zvinonyungudutsa panguva chaiyo. Kupararira kunodzorwa nedensity kunoderedza kudzika kwependi uye kunogadzirisa kusawirirana kwemvura kunokonzerwa nekuchinjika kwe viscosities. Nzira dzekuyera huwandu hwemvura dzinovandudza mashandiro uye dzinoona kuti machira emapuranga ane hushamwari nezvakatipoteredza ane kupenya kwakafanana, kugara kwenguva refu, uye mwero wekuomesa. Kudzivirira kupatsanurwa uye kuungana kunovimbisa kupera kwehuni dzinobuda mumvura nguva dzose kuti dzishandiswe mumaindasitiri.
Matambudziko Ekuyera Kuwanda Kwevanhu Munguva Yechokwadi
Kusiyana kwezvikafu mukugadzirwa kwe ethyl acetate kunokanganisa zvakananga kinetics ye esterification. Kusachena, huwandu hwemvura, uye kuchinja kwe reactant ratios zvinochinja mwero we reaction uye kuchinja ma profiles e density, zvichikonzera kusawirirana kwehuwandu hwechigadzirwa. Tembiricha yemaitiro inogona kuchinjika ne ±5°C, uye shanduko dzekumanikidzwa kwepamusoro pe ±0.1 bar dzinokanganisa nzira chaiyo dzekuyera density yemvura, zvichida kuti inline temperature transmitter uye inline pressure transmitter inputs dzigadziriswe.
Zvinhu zvakasimba zvakasungirirwa uye kuchinja kwe viscosity kunoomesa kurongeka kwe sensor. Inline density metres uye inline viscosity metres kubva kuLonnmeter zvinogona kukanganiswa kana strip load ikakwira kupfuura 50 μm kana viscosity ikapfuura 2000 cP, zvichikanganisa kuverenga. Kusiyana kwe batch-to-batch—kwakajairika mumatanho ekugadzira coating emaindasitiri—kunowedzera kusava nechokwadi mukudzora hunhu hwezvigadzirwa zvekupedzisira, kunyanya kana zvinhu zvisina kugadzirwa zvichichinja vhiki nevhiki.
Kugadzika kwezvikamu uye kupatsanurwa kwemvura, kunowanzoitika pakusanganisa machira ehuni anofambiswa nemvura, kunotungamira kune zviratidzo zvekuwanda zvisingavimbike mukuyerera kwezvikamu zvakawanda. Kuwanda kwehuwandu hwe0.02 g/cm³ kunogona kuitika mumapaipi kana matangi, zvichikonzera kutsauka pakupedzwa kwehuni dzinofambiswa nemvura. Matambudziko aya anosimbisa kudiwa kwekuyera huwandu hwemvura pasi pemamiriro ezvinhu akanyatsodzorwa kuti huni dzinofambiswa nezvakatipoteredza dzive dzakachengeteka.
Mabhenefiti ekubatanidza Inline Density Meters/Concentration Meters
Mamita ekudzikisa huwandu hwezvinhu uye mamita ekudzikisa huwandu hwezvinhu, akadai seaya anobva kuLonnmeter, anowedzera kudzora mashandiro ekugadzira ethyl acetate. Anoita kuti pave nekuonekwa kwemhinduro dzisina kutsanangurwa, zvichiita kuti pave nekukasira kugadziriswa kweFischer esterification step kana panguva yekusanganisa. Data renguva chaiyo rinoderedza kutsauka kwemaitiro, zvichiita kuti goho riwedzere kuenderana ne95%.
Nzira dzekuyera huwandu hwemvura dziri mukati dzinobatsira kuchengetedza kuchena kwechigadzirwa panguva yekudiridza nekucheneswa. Izvi zvinoderedza kushandiswa patsva kunodhura uye marara ezvinhu zvisina kugadzirwa, zvakakosha pakugadzirwa kwe ethyl acetate zvakanaka.
Mukugadzirwa kwependi yemapuranga anogadzirwa nemvura, kudzora huwandu hwemukati kunoita kuti bhachi rega rega riumbe firimu rakafanana. Kuwanda kwakasimba kunoderedza zvikuru zvinokonzera kutsemuka kwefirimu uye kuedza kudzivirira sezvo zvichideredza kusawirirana kwe solvent. Zvinoderedzawo zvakananga zvinokonzera kutsemuka kwependi nekugadzirisa, zvichiita kuti ishandiswe nguva dzose uye iome.
Kumbira mutengo wakagadzirirwa we inline density meter. Gadzirisa matambudziko akakomba mukugadzirwa kwe ethyl acetate nekushandisa nzira dzakarurama dzekuyera density yemvura. Wedzera matanho ekugadzira coating yeindasitiri, kubva pa ethyl acetate process flow diagram kusvika pakushandisa waterborne wood coating application. Gadzirisa zvikonzero zvekupwanyika kwemafirimu nematambudziko ekudzivirira, deredza zvikonzero zvekudonha kwependi nekugadzirisa, uye gadzirisa maitiro ako e wood coating ane hushamwari nezvakatipoteredza nekuyera density yemvura zvakananga mukati. Chengetedza kugadzirwa kwakafanana, deredza marara, uye vandudza hunhu hwe wood borne waterborne.
