Uninzi lweefumigants zinokufikelela kwisiphumo esifanayo se-insecticidal ngokugcina ixesha elifutshane kwi-concentration ephezulu okanye ixesha elide kwi-concentration ephantsi. Izinto ezimbini eziphambili zokumisela umphumo we-insecticidal kugxininiso olusebenzayo kunye nexesha lokugcinwa koxinzelelo olusebenzayo. Ukunyuka kokugxininiswa kwe-ejenti kuthetha ukunyuka kweendleko zokufunxa, okunoqoqosho kunye nokusebenzayo. Ngoko ke, ukwandisa ixesha lokutshisa ngokusemandleni kuyindlela efanelekileyo yokunciphisa iindleko zokutshisa kunye nokugcina umphumo we-insecticidal.
Iinkqubo zokusebenza zokufunxa zichaza ukuba ukuxinana komoya kwindawo yokugcina impahla kulinganiswa ngesiqingatha sobomi, kwaye ixesha loxinzelelo lokuhla ukusuka kwi-500Pa ukuya kwi-250Pa ngu-≥40s kwizitora ezisicaba kunye ne-≥60s kwizitora ezingqukuva ezinganzulwanga ukuhlangabezana neemfuno zokutshisa. Nangona kunjalo, ukuxinana komoya kwiindawo zokugcina iimpahla zezinye iinkampani zokugcina zimbi kakhulu, kwaye kunzima ukuhlangabezana neemfuno zokuxinana komoya zokutshisa. Isenzeko sesiphumo esibi sokubulala izinambuzane sihlala sisenzeka ngexesha lenkqubo yokufunxa iinkozo ezigciniweyo. Ngoko ke, ngokutsho koxinzelelo lomoya kwiindawo zokugcina iimpahla ezahlukeneyo, ukuba i-arhente yogxininiso ikhethiweyo, inokuqinisekisa zombini umphumo we-insecticidal kunye nokunciphisa iindleko ze-arhente, okuyingxaki engxamisekileyo ukuba isonjululwe kuyo yonke imisebenzi yokufunxa. Ukugcina ixesha elisebenzayo, indawo yokugcina impahla kufuneka ibenomoya olungileyo, ke yintoni ubudlelwane phakathi koxinzelelo lomoya kunye nokuxinana kwearhente?
Ngokweengxelo ezifanelekileyo, xa ukuqina komoya kwindawo yokugcina impahla kufikelela kwi-188s, isiqingatha sobomi besigxina se-sulfuryl fluoride singaphantsi kwe-10d; xa ukuxinwa komoya kwindawo yokugcina i-53s, isiqingatha sobomi besigxina se-sulfuryl fluoride singaphantsi kwe-5d; xa ukuxinwa komoya kwindawo yokugcina i-46s, isiqingatha esifutshane sobomi besigxina se-sulfuryl fluoride yi-2d kuphela. Ngexesha lenkqubo yokutshisa, iphezulu i-sulfuryl fluoride concentration, ngokukhawuleza ukubola, kunye nesantya sokubola kwegesi ye-sulfuryl fluoride ikhawuleza kunaleyo yegesi ye-phosphine. I-Sulfuryl fluoride inokungena ngamandla kunephosphine, okukhokelela kuxinzelelo lwegesi olufutshane lwesiqingatha sobomi kunephosphine.
Sulfuryl fluorideifumigation ineempawu zesibulali-zinambuzane esikhawulezayo. Uxinaniso olubulalayo lwezitshabalalisi ezininzi ezigciniweyo eziziinkozo ezifana nooqongqothwane abaneempondo ezinde ezisicaba, ooqongqothwane abasarha saw, iintwala zombona, kunye neentwala zeencwadi zokufunxa ii-48h ziphakathi kwe-2.0~5.0g/m'. Ngoko ke, ngexesha lenkqubo yokufunxa, ii-sulfuryl fluorideUgxininiso kufuneka lukhethwe ngokufanelekileyo ngokweentlobo zezinambuzane kwindawo yokugcina impahla, kwaye injongo ye-insecticide esheshayo inokufezekiswa.
Kukho izinto ezininzi ezichaphazela izinga lokubola kweigesi ye-sulfuryl fluorideugxininiso kwindawo yokugcina impahla. Ukuqina komoya kwendawo yokugcina izinto yeyona nto iphambili, kodwa ikwanxibelelene nezinto ezinje ngohlobo lwenkozo, ukungcola, kunye ne-porosity yemfumba yeenkozo.
