Nyob rau xyoo 1990, kev tsim khoom hauv tsev ntawm ammonia thiamethoxam oxime acid ntawm ntau tshaj 20 lub lag luam kev lag luam kev sib tw yog nce kev sib tw ntawm cov lag luam yog tshwm sim los ntawm kev innovation thawj zaug poob nqi txog rau tam sim no lub domestic ammonia thiamethoxam oxime acid ntau lawm nqi yuav raug txo kom tsawg dua. 50000 / tons ntawm AE - active ester ntau lawm tus nqi txo los ntawm ntau tshaj 40 m / tons rau tam sim no tsawg tshaj li 160000 / ton txawm tias txhua tus neeg tsim khoom yog cov ntaub ntawv tsis pub lwm tus paub tab sis siv ntau yam kev siv cov thev naus laus zis tshiab feem ntau hauv 2 ~ 3 xyoo. yuav tau txais kev txhawb nqa yog tias cov tuam txhab thoob plaws lub tebchaws tsis muaj peev xwm txhim kho tau zoo nws feem ntau nyuaj rau hauv nruab nrab mus rau lub sij hawm ntev khaws cov nqi thiab cov nqi poob qis sai heev.

Niaj hnub no ammonia thiamethoxam oxime acid tau mus txog qhov kev sib tw dawb-kub ua rau qee qhov ua ntej nkag mus rau hauv kev lag luam thiab muaj qee qhov kev lag luam uas twb muaj lawm raws li koj tus kheej cov kev siv zog thiab peev xaiv los muab qee yam khoom xws li hebei jintong. Kev lag luam tshuaj chemical yog kev tsim khoom hauv tsev ntawm ammonia thaum ntxov thiamethoxam oxime acid (xws li kev lag luam AE - nquag ester) tab sis tam sim no tau tso tseg cov khoom tsim tawm ntawm cov nyiaj lawv tus kheej zoo dua ntawm triazine nplhaib thiab ua ob npaug rau nws cov peev txheej ntawm 5 tons / hli. thawj tsim muaj peev xwm ntawm ntau tshaj 10 lub sij hawm es tsis txhob shandong jincheng tshuaj yog nres triazine nplhaib ntau lawm thiab centralized peev siv nyob rau hauv zus tau tej cov ammonia thiamethoxam thiab AE - oxime acid.

Cov ester nquag uas cov zis tau mus txog 70 tons / hli thiab 50 tons / hli Txawm hais tias tam sim no vim muaj ntau yam hauv tsev ammonia thiamethoxam oxime acid thiab triazine nplhaib, qhov tshwm sim ntawm cov khoom tawm tab sis tsis muaj ntau lub sijhawm rau kev pib ua haujlwm tuaj yeem siv rau. kev tsim cov khoom no yog coj mus rau ib txoj kab tshiab ntawm kev lag luam muaj zog nyob rau hauv ntau txoj hauv kev nws yog ib qho nyuaj rau kev sib tw nrog cov tuam txhab tsim no thaum lub lag luam volatility thiab ib pawg ntawm cov lag luam yuav raug tshem tawm.
