Insecticides manufacturing txheej txheem yog ib tug complex txheej txheem ntawm ntau sub-processes.

Los ntawm kev npaj cov khoom siv raw mus rau theem kawg ntawm kev ntim khoom thiab kev xa khoom, ntau cov txheej txheem tuaj rau hauv kev ua si thiab ntau qhov sib txawv inter-logistics cov ntsiab lus yog siv nyob rau hauv cov txheej txheem cov ntaub ntawv raug tuav nyob rau hauv tib lub Hoobkas los yog txawm nyob rau hauv ntau semi-tiav khoom factories.

Txawm hais tias txhua qhov kev lag luam yuav muaj cov txheej txheem sib txawv me ntsis, peb tuaj yeem nqaim cov txheej txheem tsim tshuaj tua kab rau hauv ob kauj ruam dav - (a) txheej txheem kev tsim tshuaj tua kab thiab (b) txheej txheem tsim khoom thiab xa khoom ntawm cov khoom kawg.

Nyob rau hauv cov txheej txheem active ingredient ntau lawm, ntau yam organic thiab inorganic raw cov ntaub ntawv yog tiav nyob rau hauv reactors thiab dhau los ntawm fractionation kab thiab cov active technical qib tshuaj tua kab npaj rau shipping.Muaj qee cov kauj ruam ntxiv nrog rau kev ziab thiab ntim khoom.

Txhawm rau txhim kho kev thauj mus los, tuav, thiab tawg ntawm cov tshuaj tua kab, cov khoom xyaw nquag yuav tsum tau tsim rau hauv cov khoom siv kawg.Nyob rau hauv lub formulation txheej txheem ntawm cov khoom kawg, cov active ingredient yog hmoov rau hauv cov hmoov zoo nyob rau hauv ib lub zeb.Cov hmoov zoo ntawm cov khoom xyaw nquag yog sib xyaw nrog lub hauv paus hnyav thiab lwm yam khoom xyaw.Cov khoom kawg yuav qhuav los yog kua thiab ntim raws li nyob rau hauv lub thawv thiab lub raj mis feem.

Nyob rau hauv ntau cov kauj ruam uas yuav tsum tau txav ntawm raw khoom, sib tsoo cov hlab ntsha blanketing thiab lwm yam inert gas yuav tsum tau tiv thaiv oxidation ntawm ntau rhiab heev thiab volatile tshuaj.Hauv cov xwm txheej zoo li no, nitrogen feem ntau yog siv los ua cov roj ntawm kev xaiv.Nitrogen ntau lawm on-site yog ib qho yooj yim thiab raug nqi, ua rau nws yog ib qho zoo tagnrho xaiv rau inert mediums.Qhov twg yuav tsum muaj cov khoom siv lossis cov khoom siv pneumatic, Nitrogen yog siv los ua tus nqa khoom.Thaum lub sij hawm npaj, inter-process cia tso tsheb hlau luam tej zaum yuav tsum tau rau khaws cia ib tug semi-tiav khoom.Nyob rau hauv cov ntaub ntawv ntawm cov tshuaj volatile los yog chemicals lwm yam yuav ua rau lwj vim kev sib cuag nrog oxygen, yog khaws cia nyob rau hauv lub nitrogen purged tso tsheb hlau luam thiab ces nitrogen blanketing ntawm cov tso tsheb hlau luam yog ua nyob rau hauv ib tug tas mus li lub hauv paus kom tsis txhob muaj ib tug ntxiv ingress ntawm oxygen mus rau hauv lub tank.

Lwm nthuav kev siv nitrogen yog nyob rau hauv lub ntim ntawm cov khoom xyaw nquag los yog cov khoom kawg, qhov twg raug oxygen yog teeb meem thiab tsis tsuas yog spoils lub kawg-cov khoom ntxov ntxov tab sis kuj txo cov txee lub neej ntawm cov khoom.Ib qho tshwm sim nthuav dav hauv cov tshuaj tua kab yog kev sib tsoo ntawm lub raj mis uas cov cua tso rau hauv lub raj mis lub taub hau ua rau muaj kev cuam tshuam tsis zoo sab hauv thiab ua rau lub raj mis tsim lub tshuab nqus tsev thiab yog li ua rau deshaping lub raj mis.Yog li ntawd, ntau lub tuam txhab tau xaiv los ntxuav lub raj mis nrog nitrogen kom tshem tawm cov huab cua ntawm lub raj mis ua ntej sau cov tshuaj tua kab thiab tseem ua rau lub taub hau nrog nitrogen kom tsis txhob muaj huab cua nyob hauv lub raj mis, ua ntej nws raug kaw.
