Amayeza aphakathi

Ngeminyaka yoo-1990, imveliso yasekhaya ye-ammonia thiamethoxam oxime acid yamashishini angaphezu kwama-20 kukhuphiswano lwemarike lwamashishini luya lukhula ukhuphiswano oluqatha phakathi kwamashishini lubangelwa lutshintsho lobuchwephesha lokuqala oluhlayo ukuya kuthi ga ngoku, iindleko zokuvelisa iasidi ye-ammonia yasekhaya zinokucuthwa zibe ngaphantsi kunoko. I-50000 / iitoni ze-AE - iindleko zemveliso ye-ester esebenzayo zincitshisiwe ukusuka ngaphezulu kwe-40 m / iitoni ukuya ngoku ngaphantsi kwe-160000 / iitoni nangona umenzi ngamnye eyimfihlelo yobugcisa kodwa athathe iindlela ezahlukeneyo zokusetyenziswa kobuchwepheshe obutsha ngokubanzi phakathi kweminyaka emi-2 ukuya kwemi-3. izakufumana ukunyuselwa ukuba iinkampani kwilizwe liphela azinasakhono sophuhliso kudla ngokuba nzima ukuba kwixesha eliphakathi ukuya kwelide zihambisane neendleko kwaye amaxabiso ehle isantya ngokukhawuleza.

Namhlanje i-ammonia thiamethoxam i-oxime acid ifikelele kumlinganiselo wokhuphiswano olumhlophe-olushushu yenza ukufikelela kwangaphambili kwishishini kwaye inomlinganiselo othile weshishini esele ixhomekeke kumandla akho obugcisa kunye nenkunzi ngokukhetha ukuyeka ezinye zeemveliso ezifana ne-hebei jintong. Ishishini lemichiza yamayeza yimveliso yasekhaya ye-ammonia ekuqaleni kwe-thiamethoxam oxime acid (kubandakanya ishishini le-AE - i-ester esebenzayo) kodwa ngoku ishiywe imveliso yemveliso yemali ngokwabo ingcono kwiringi ye-triazine kwaye iphindwe kabini amandla ayo okuvelisa iitoni ezi-5 / ngenyanga Umthamo woyilo woqobo wamaxesha angaphezu kwe-10 endaweni ye-shandong jincheng imichiza iyamiswa imveliso yeringi ye-triazine kunye nenkunzi ephakathi esetyenziselwa ukuveliswa kwe-ammonia thiamethoxam kunye ne-AE - i-oxime acid.

I-ester esebenzayo leyo imveliso ifikelele kwiitoni ezingama-70/ngenyanga kunye neetoni ezingama-50/ngenyanga Nangona ngoku ngenxa yezizathu ezahlukeneyo zasekhaya i-ammonia thiamethoxam oxime acid kunye neringi ye-triazine, isenzeko sokungabikho kwesitokhwe kodwa asilothuba lininzi lokuqalisa-ups kunokuthatha Ukwenziwa kwezi mveliso kuthathela kumgca omtsha wamandla abanzi eshishini ngeendlela ezininzi kunzima ukukhuphisana nala mafemu asekiweyo nje ukuba ukuguquguquka kwemarike kunye neqela lamashishini lipheliswe.
