Hukama huripo pakati pekuwanda kwemafuta esulfuryl fluoride uye kusimba kwemhepo mudura

Mishonga yakawanda inouraya zvipembenene inogona kuwana simba rakafanana rekuuraya zvipembenene nekuchengetedza nguva pfupi iri pahuwandu hwakawanda kana nguva refu iri pahuwandu hushoma. Zvinhu zviviri zvikuru pakuona simba rekuuraya zvipembenene ndezvekuti mishonga inouraya zvipembenene inoshanda uye kuti mishonga inouraya zvipembenene inoshanda. Kuwedzera kwehuwandu hwemishonga kunoreva kuwedzera kwemutengo wemishonga inouraya zvipembenene, izvo zvisingadhuri uye zvinoshanda. Nokudaro, kuwedzera nguva yemishonga inouraya zvipembenene zvakanyanya sezvinobvira inzira inoshanda yekuderedza mutengo wemishonga inouraya zvipembenene uye kuchengetedza simba remishonga inouraya zvipembenene.

Maitiro ekushandisa fumigation anoti kusimba kwemhepo mudura kunoyerwa nehafu yehupenyu, uye nguva yekumanikidzwa kudzikira kubva pa500Pa kusvika pa250Pa i ≥40s dzematura akatsetseka uye ≥60s dzematura akatenderera asina kudzika kuti asvike pazvinodiwa zvefumigation. Zvisinei, kusimba kwemhepo mudura remamwe makambani ekuchengetera zvinhu kwakaderera, uye zvakaoma kusangana nezvinodiwa zvefumigation. Chiitiko chekushaya simba kwekuuraya zvipembenene chinowanzoitika panguva yekufuridzira zviyo zvakachengetwa. Naizvozvo, zvichienderana nekusimba kwemhepo mudura dzakasiyana, kana huwandu hwakakwana hwemushonga hukasarudzwa, zvinogona kuve nechokwadi chekuti hutachiona hunoshanda uye kuderedza mutengo wemushonga, inova dambudziko rinokurumidzira kugadziriswa pamabasa ese efumigation. Kuti irambe ichishanda zvakanaka, dura rinofanira kuva nekusimba kwemhepo kwakanaka, saka hukama huripo pakati pekusimba kwemhepo nekusimba kwemushonga ndehupi?

Sekureva kwemishumo yakakodzera, kana kusimba kwemhepo mudura remumba kwasvika makore ekuma188, huwandu hwakareba hwehafu yehupenyu hwesulfuryl fluoride hunenge huri pasi pe10d; kana kusimba kwemhepo mudura remumba kuri 53s, huwandu hwakareba hwehafu yehupenyu hwesulfuryl fluoride hunenge huri pasi pe5d; kana kusimba kwemhepo mudura remumba kuri 46s, hafu yehupenyu hupfupi hwehuwandu hwakareba hwesulfuryl fluoride hunenge huri 2d chete. Munguva yekutsvaira, huwandu hwesulfuryl fluoride hwakawanda, kuora kunokurumidza, uye mwero wekuora kwegasi resulfuryl fluoride unokurumidza kupfuura wegasi rephosphine. Sulfuryl fluoride ine simba rakasimba rekupinda kupfuura phosphine, zvichikonzera huwandu hupfupi hwehafu yehupenyu mugasi kupfuura phosphine.

Sulfuril fluorideKufuridzira mushonga unokurumidza kushandiswa semushonga unouraya. Kuwanda kwezvipembenene zvikuru zvakachengetwa muzviyo zvakaita semabere marefu ane nyanga dzakareba, mabere madiki, zvikwekwe zvechibage, uye inda dzemabhuku kwemaawa makumi mana nemasere ekufuridzira mushonga unopisa uri pakati pe2.0 ~ 5.0g/m². Saka, panguva yekufuridzira mushonga unopisa,sulfuryl fluoridehuwandu hwezvipembenene hunofanira kusarudzwa zvine musoro zvichienderana nerudzi rwezvipembenene zviri mudura, uye chinangwa chekushandisa zvipembenene nekukurumidza chinogona kuzadzikiswa.

Kune zvinhu zvakawanda zvinokanganisa mwero wekuora kwegasi resulfuryl fluorideKuwanda kwemhepo mudura. Kusimba kwemhepo mudura ndicho chinhu chikuru, asi zvine chekuitawo nezvinhu zvakaita serudzi rwezviyo, tsvina, uye kupinza kwemurwi wezviyo.
