How Concentration and Viscosity Affect Product Quality in Pesticide Production

Uxinzelelo lwe-pesticide kunye ne-viscosity ye-pesticide zimbini iiparamitha eziphambili ezimisela ngokuthe ngqo umgangatho wemveliso. Uzinzo kunye nengqiqo yazo zihamba kuyo yonke inkqubo yokuvelisa izitshabalalisi kunye nenkqubo yokuqulunqa izitshabalalisi, okushiya impembelelo ebalulekileyo ekusebenzeni, ukuzinza, ukhuseleko kunye nokusebenziseka kwezibulali zinambuzane.

I. Impembelelo yokuGxininiswa kweZitshabalalisi kuMgangatho weMveliso

Uxinzelelo lwezitshabalalisi lubhekisa kumxholo wezithako ezisebenzayo okanye amacandelo asebenzayo kwimveliso yesitshabalalisi. Ukuchaneka kwayo kunye nokuzinza zizinto eziphambili ezichaphazela umgangatho ongundoqo wezibulali-zinambuzane.

1. Impembelelo kwiNdlela eFanelekileyo yezibulali-zinambuzane

Ubuninzi bezithako ezisebenzayo bumisela amandla e-pesticide ukulawula izitshabalalisi, izifo okanye ukhula. Ukuba ugxininiso luphantsi kakhulu, izithako ezisebenzayo kumthamo weyunithi yesibulali-zinambuzane azikwazi ukufikelela kwidosi esebenzayo efunekayo ukubulala okanye ukuvimbela izinto eziphilayo ezijoliswe kuzo.

Ngokuchasene noko, ukuba ugxininiso luphezulu kakhulu, luya kuzisa uluhlu lweengxaki. Kwelinye icala, kunokubangelai-phytotoxicitykwizityalo. Uxinzelelo oluphezulu lwezithako ezisebenzayo lusenokonakalisa ubume bokuphila kwamagqabi, izikhondo okanye iingcambu, nto leyo ekhokelela ekubeni igqabi libe tyheli, ukubuna, ukonakala kweziqhamo kunye nezinye izinto.

Kwelinye icala, ukugxininiswa okugqithisileyo kuya kwandisa intsalela yezitshabalalisi kwindalo esingqongileyo nakwizityalo, ezingangcolisi nje umhlaba kunye nemithombo yamanzi kodwa zibeke imingcipheko enokubakho kwimpilo yabantu neyezilwanyana ngekhonkco lokutya.

2. Impembelelo kuZinzo lweMveliso

Kwinkqubo yokuqulunqa i-pesticide, ukuxinwa kwenkqubo yesisombululo kuchaphazela ukuzinza komzimba kunye neekhemikhali zemveliso. Ngokomzekelo, kwi-emulsifiable concentrate pesticides, ukuba ukuxinwa kweyeza lokuqala liphezulu kakhulu kwaye lidlula ukunyibilika kwalo kwi-solvent, kulula ukubangela i-crystallization okanye imvula ngexesha lokugcinwa.

Oku akunciphisi kuphela ukufana kwemveliso kodwa kwenza ukuba ukugxininiswa kwezithako ezisebenzayo kwiindawo ezahlukeneyo zingahambelani. Ukongeza, kwiimveliso zokubulala izitshabalalisi ezifuna ukuchasana neekhemikhali ngexesha lemveliso, ukuxinana kwee-reactants kuchaphazela ukulingana kokusabela kunye nokusulungeka kwemveliso.

Ukugxininiswa okungaqhelekanga kunokukhokelela ekuphenduleni okungaphelelanga okanye ukuveliswa kweemveliso ezininzi, okuya kunciphisa umxholo osebenzayo wemveliso kunye nokwazisa ukungcola okuyingozi.

3. Impembelelo kwiBatch Consistency

Ugxininiso oluzinzileyo oluhluka kwiibhetshi lungonakalisa isidima sabavelisi okanye abavelisi. Iiyantlukwano zogxininiso ezicacileyo zenza mandundu ukusebenza kunye nokhuseleko lweemveliso kumaxesha ahlukeneyo.

II. Impembelelo ye-Pesticide Viscosity kuMgangatho weMveliso

I-pesticide viscosity yipropathi ebonakalayo ebonisa ubumanzi kunye nokukhuhlana kwangaphakathi kokwenziwa kweyeza. Inxulumene ngokusondeleyo nokuzinza, ukusetyenziswa kunye nesiphumo sokusetyenziswa kwemveliso.

1. Impembelelo kuZinzo loMzimba lweeMveliso

I-Viscosity yinto ephambili yokugcina i-dispersion state of particles or droplets in the formulations of pesticide. Ukumisa i-ejenti ye-pesticides, i-viscosity efanelekileyo inokwenza inkqubo ye-colloidal ezinzileyo, egubungela kwaye imise amasuntswana ezinto eziqinileyo ezisebenzayo ngokulinganayo phakathi.

Ukuba i-viscosity iphantsi kakhulu, ubunzima beengqungquthela buya kudlula ukuchasana kwe-medium, ekhokelela ekubeniintlenga yamasuntswanangexesha lokugcina. Emva kwe-sedimentation, iinqununu zilula ukuhlanganisana, kwaye nangona zishukunyiswa, kunzima ukubuyisela isimo esifanayo, okubangela ukusabalalisa okungafaniyo kwezinto ezisebenzayo. Xa isetyenzisiwe, ukugxininiswa kwenxalenye kunye neengqungquthela ezininzi kuphezulu kakhulu, ngelixa ukugxininiswa kwenxalenye eneengqungquthela ezincinci kuphantsi kakhulu, kuchaphazela kakhulu umphumo wokulawula. Kwi-emulsions efana ne-microemulsions, i-viscosity efanelekileyo inokuqinisekisa ukuzinza kwamaconsi e-emulsion. Ukuba i-viscosity iphantsi kakhulu, amaconsi e-emulsion kulula ukudibanisa, okukhokelela ekuqhekekeni kwe-emulsion kunye ne-stratification. Ngokwahlukileyo, ukuba i-viscosity iphezulu kakhulu, i-fluidity yemveliso ihlwempuzekile, eya kubangela ubunzima kwimveliso, njengokuvaleka kwemibhobho ngexesha lokuthutha kunye nokuxuba ukungalingani ngexesha lenkqubo yokuvelisa.

2. Impembelelo ekuSebenziseni kunye neMpembelelo yokuSebenza

I-Viscosity ichaphazela ngokuthe ngqo ukusetyenziswa kwezibulali-zinambuzane ngexesha lokufaka isicelo. Izibulali-zinambuzane ezine-viscosity ephakathi zine-fluidity efanelekileyo, ekulungele ukuhlanjululwa kunye nokutshiza. Ngokomzekelo, izibulali-zinambuzane ezinamanzi ezine-viscosity efanelekileyo zinokuxutywa ngokulula namanzi nakweyiphi na imilinganiselo, kwaye ulwelo lokutshiza lunokuthi lube ne-atomized ngokulinganayo ngesitshizi, ukuqinisekisa ukuba i-pesticide ifakwe ngokufanayo kumphezulu wezityalo. Ukuba i-viscosity iphezulu kakhulu, i-pesticide inzima ukuyihlambulula, kwaye i-sprayer ilula ukuyivimba ngexesha lokutshiza, engagcini nje ukunciphisa ukusebenza kakuhle kodwa yenza ukuba i-pesticide ingakwazi ukusetyenziswa ngokulinganayo. Ukongeza, amayeza okubulala izitshabalalisi aneviscosity ephezulu kulula ukwenza iifilim ezishinyeneyo zolwelo kumphezulu wesityalo, ezinokubangela i-phytotoxicity kwiimeko ezinzima. Kwi-paste okanye i-colloid pesticides esetyenziselwa i-smear, i-viscosity inquma ukunamathela kunye nokusabalalisa. I-viscosity efanelekileyo inokwenza ukuba i-pesticide ibambelele ngokuqinileyo kwindawo yesicelo kwaye isasazeke ngokulinganayo, iqinisekisa ukufunxa okusebenzayo kwezityalo okanye izinambuzane. Ukuba i-viscosity iphantsi kakhulu, i-paste ilula ukuhamba kunye nokulahlekelwa, ukunciphisa izinga lokusetyenziswa okusebenzayo; ukuba i-viscosity iphezulu kakhulu, kunzima ukusasazeka, okubangela ukusabalalisa okungafaniyo.

3. Impembelelo kuGcino kunye neNtsebenzo yoThutho

I-Viscosity ikwachaphazela ukugcinwa kunye nokusebenza kokuthutha kweemveliso ze-pesticide. I-pesticides ene-viscosity ezinzileyo ayilula ukutshintsha imeko yabo yomzimba ngexesha lokugcinwa kunye nokuthutha. Ngokomzekelo, i-low-viscosity liquid ye-pesticides ene-viscosity efanelekileyo ayilula ukuvuza ngexesha lokuthutha, kunye ne-high-viscosity pastes akulula ukuguqula okanye ukwahlula phantsi kwamandla angaphandle. Ukuba i-viscosity ayizinzile, njengokunciphisa okukhulu kwe-viscosity ngenxa yokushisa okuphezulu ngexesha lokugcinwa, kunokukhokelela ekutshintsheni kwiimpawu ezibonakalayo zemveliso, ezifana nokunyuka kwamanzi kunye nokuvuza okulula; okanye ukuba i-viscosity iyanda ngenxa yokushisa okuphantsi, kunokubangela ukuba imveliso ibe lukhuni, ibe nzima ukuyikhupha kwaye isebenzise ngokuqhelekileyo.

III. Impembelelo ye-Synergistic yokuNxibelela kunye ne-Viscosity kuMgangatho weMveliso

Kweyona nkqubo yokuvelisa izibulali-zinambuzane, ukuxinana kwe-pesticide kunye ne-pesticide viscosity ayichaphazeli umgangatho wemveliso ngokuzimeleyo kodwa isebenzisana kunye nokubambisana. Ukulinganisa okufanelekileyo kokugxila kunye ne-viscosity ngundoqo ekuqinisekiseni izitshabalalisi ezikumgangatho ophezulu. Ngokomzekelo, kwimveliso ye-agent yokumisa, ukuxinwa kwezinto ezisebenzayo kugqiba ukusebenza, ngelixa i-viscosity iqinisekisa ukusabalalisa okufanayo kwezi zithako ezisebenzayo. Kuphela xa ugxininiso luchanekile kwaye i-viscosity ifanelekile ukuba izithako ezisebenzayo zikwazi ukuhlala ngokuzinzile ekulungiseleleni kwaye zenze ukusebenza kwazo ngokulinganayo. Ukuba i-concentration ichanekile, kodwa i-viscosity iphantsi kakhulu, iinqununu zesithako esisebenzayo ziya kuhlala, ezibangele ukugxininiswa okungalinganiyo ekusebenziseni ngokwenene; ukuba i-viscosity ifanelekile kodwa ugxininiso aluchanekanga, luya kukhokelela kwiingxaki ezifana nokungasebenzi ngokwaneleyo okanye i-phytotoxicity. Kwinkqubo ye-emulsification ye-emulsification concentrates, ukuxinwa kweyeza lokuqala kunye ne-emulsifier kuchaphazela ukubunjwa kwe-emulsion, kwaye i-viscosity ichaphazela ukuzinza kwenkqubo ye-emulsion. Ezi zimbini zisebenza kunye ukuqinisekisa ukuba i-emulsifiable concentrate ihlala ifana kwaye izinzile ngexesha lokugcinwa kunye nokusetyenziswa, kwaye inokusebenzisa ukusebenza kwayo ngokufanelekileyo emva kokuhlanjululwa.

Ukuqukumbela, kwinkqubo yokuvelisa i-pesticide, ulawulo olungqongqo lwe-pesticide concentration kunye ne-pesticide viscosity sisiqinisekiso esibalulekileyo sokuphucula umgangatho wemveliso. Ngokubeka iliso ngexesha lokwenyani kunye nokulawulwa kwezi parameters zimbini ngezixhobo ezinje ngeemitha zoxinaniso lwe-intanethi kunye ne-viscometers ye-intanethi (ezifana neemveliso ezisebenza kakhulu ezibonelelwa yiLonnmeter), amashishini ezinambuzane anokuqinisekisa ukuzinza kokusebenza kwemveliso, ukomeleza ukuzinza komzimba kunye neekhemikhali, ukuphucula ukusebenziseka, kwaye ngaloo ndlela avelise iimveliso zezitshabalalisi ezikumgangatho ophezulu ezihlangabezana neemfuno zokhuseleko lwezolimo.
