Ubudlelwano phakathi kokugxilwa kwegesi ye-sulfuryl fluoride kanye nokuqina komoya endaweni yokugcina impahla

Amafumigant amaningi angafinyelela umphumela ofanayo we-insecticidal ngokugcina isikhathi esifushane ekugxilweni okuphezulu noma isikhathi eside ekugxilweni okuphansi. Izinto ezimbili ezinkulu zokunquma umphumela wokubulala izinambuzane ukugxilisa ingqondo okusebenzayo kanye nesikhathi esisebenzayo sokunakekela ukugxilisa ingqondo. Ukwenyuka kokugxila kwe-ejenti kusho ukunyuka kwezindleko zokufuthwa, okunomnotho futhi okuphumelelayo. Ngakho-ke, ukwelula isikhathi sokufuthwa ngangokunokwenzeka kuyindlela ephumelelayo yokunciphisa izindleko zokufuthwa kanye nokugcina umphumela wokubulala izinambuzane.

Izinqubo zokusebenza zokuthungula zicacisa ukuthi ukucinana komoya kwendawo yokugcina impahla kukalwa ngesigamu sempilo, futhi isikhathi sokucindezela ukwehla ukusuka ku-500Pa kuya ku-250Pa singu-≥40s ezindlini zokugcina impahla eziyisicaba kanye no-≥60s ezindlini zokugcina eziyindilinga ezingashoni ukuze kuhlangatshezwane nezidingo zokufutha. Kodwa-ke, ukuqina komoya kwezindawo zokugcina izimpahla zezinye izinkampani zokugcina impahla kubi kakhulu, futhi kunzima ukuhlangabezana nezidingo zokuqina komoya zokufuthwa. Isenzo somphumela omubi wokubulala izinambuzane kuvame ukwenzeka phakathi nenqubo yokufuthwa kokusanhlamvu okugciniwe. Ngakho-ke, ngokusho kokuqina komoya kwezindawo zokugcina izimpahla ezihlukene, uma kukhethwa i-ejenti efanele, ingaqinisekisa umphumela wokubulala izinambuzane futhi inciphise izindleko ze-ejenti, okuyinkinga ephuthumayo okufanele ixazululwe kuyo yonke imisebenzi yokufutha. Ukuze kugcinwe isikhathi esisebenzayo, indawo yokugcina impahla idinga ukuba nomoya omuhle oqinile, ngakho-ke buyini ubudlelwano phakathi kokuqina komoya nokugxiliswa kwe-ejenti?

Ngokwemibiko efanele, lapho ukuqina komoya kwendawo yokugcina impahla kufinyelela ku-188s, isigamu sempilo ende kunazo zonke ye-sulfuryl fluoride ingaphansi kwe-10d; lapho ukuqina komoya kwendawo yokugcina impahla kungu-53s, isigamu sempilo ende kunazo zonke ye-sulfuryl fluoride ingaphansi kuka-5d; lapho ukuqina komoya kwendawo yokugcina impahla kungu-46s, isigamu sempilo emfushane kakhulu ye-sulfuryl fluoride ende iyi-2d kuphela. Ngesikhathi senqubo yokufuthwa, ukuphakama kwe-sulfuryl fluoride, ukubola ngokushesha, futhi izinga lokubola kwegesi ye-sulfuryl fluoride liyashesha kunalelo legesi ye-phosphine. I-Sulfuryl fluoride inokungeneka okunamandla kune-phosphine, okuholela ekugxilweni kwegesi okufushane uhhafu wempilo kune-phosphine.

I-Sulfuryl fluorideukufuthwa kunezici ze-insecticide esheshayo. Inqwaba ebulalayo yezinambuzane ezimbalwa ezinkulu ezigciniwe zokusanhlamvu ezifana nezibhungane ezinezimpondo ezinde eziyisicaba, amabhungane okusaha okusaha, izintwala zommbila, nezintwala zezincwadi zokufuthwa amahora angama-48 kuphakathi kuka-2.0~5.0g/m'. Ngakho-ke, ngesikhathi senqubo yokufuthwa, i-i-sulfuryl fluorideukugxila kufanele kukhethwe ngokunengqondo ngokwezinhlobo zezinambuzane endaweni yokugcina impahla, futhi umgomo wokubulala izinambuzane ngokushesha ungafinyelelwa.

Ziningi izinto ezithinta izinga lokubola kweigesi ye-sulfuryl fluorideukuhlushwa endaweni yokugcina impahla. Ukuqina komoya kwendawo yokugcina impahla kuyisici esiyinhloko, kodwa futhi kuhlobene nezici ezifana nohlobo lokusanhlamvu, ukungcola, kanye ne-porosity yenqwaba yokusanhlamvu.
