Nws kuj tseem siv tau los ua cov khoom siv raw lossis nruab nrab los koom rau lwm yam tshuaj synthesical, thiab cov tshuaj lom neeg ntawm cov khoom siv tsis tseem ceeb.
Tsiv thiab thaij duab
Cov compound no tuaj yeem ua ib qho tseem ceeb ntawm cov xim zaj duab xis ua cov neeg sawv cev. Thaum lub sijhawm ua, cov tshuaj no nrawm nrawm nrawm nrawm, pab tshem tawm cov tshuaj ntau dhau los ntawm zaj duab xis, thiab ua kom cov xim thiab pom tseeb ntawm zaj duab xis. Nyob rau tib lub sijhawm, nws kuj muaj peev xwm yaj xwm kom tshem tawm cov ntsev kom huv si thaum ua kev ua, yog li txhim kho cov duab zoo ntawm zaj duab xis. Cov compound no tuaj yeem siv rau hauv cov kev daws teeb meem dub thiab dawb los txhawb cov txiaj ntsig particle. Los ntawm kho cov ntsiab lus ntawm cov tsim tawm, cov kev pab tuaj yeem tswj hwm kev txhim kho ceev thiab duab granularity, yog li ua tiav cov qauv dub zoo nkauj thiab dawb. Hauv cov duab thaij duab, nws tseem ua lub luag haujlwm tseem ceeb. Nws tuaj yeem siv tau xim cov kev daws teeb meem los txhawb kev txhim kho ceev thiab nce zaj duab xis rhiab rhiab. Nyob rau tib lub sijhawm, nws kuj tseem tuaj yeem siv rau hauv cov xim kho cov kev daws teeb meem kom ua nrawm dua cov nyiaj ntawm cov nyiaj thiab txhim kho qhov kho kom nrawm.
Sodium Thiocyanate yog ib qho ntawm cov ntaub ntawv tseem ceeb rau kev npaj ntawm cov tshuaj tua kab, thiab cov kab tsuag thiab cov qoob loo hauv cov qoob loo hauv kev ua liaj ua teb. Los ntawm cov tshuaj tiv thaiv tshwj xeeb, sib xyaw nrog cov tshuaj tua kab thiab cov dej num hauv cov tshuaj tua kab tuaj yeem ua tau zoo los ua kom tau raws li cov kev xav tau ntawm kev xav tau kev lag luam. Nws kuj tseem siv tau ua ib qho kev tawm tsam rau qee cov nroj tsuag. Tom qab cov qoob loo tau macured, nws yog qee zaum yuav tsum siv defoliants los ua kom cov nroj tsuag nplooj poob rau cov tshuab sib sau ua ke. Raws li ib qho ntawm cov khoom xyaw zoo ntawm kev tawm tsam, nws tuaj yeem txhawb nqa cov khoom txiav ntawm cov nroj tsuag thiab txhim kho sau tau zoo. Nyob rau hauv kev lag luam mis nyuj, nws kuj tseem tuaj yeem siv ua ke nrog hydrogen peroxide rau kev khaws cia ntawm cov khoom noj mis nyuj xws li mis nyuj. Nws muaj qhov cuam tshuam ntawm kev loj hlob ntawm cov pwm, thiab los ntawm kev ntxiv nws rau cov khoom noj mis, nws tuaj yeem txuas ntxiv rau lub neej tshiab thiab zoo ntawm cov khoom noj mis nyuj. Ntxiv nrog rau qhov saum toj no-} hais siv, nws kuj tseem muaj lwm daim ntawv thov muaj peev xwm ua rau kev ua liaj ua teb. Piv txwv li, nws tuaj yeem siv los ua cov khoom siv nyoos lossis cov khoom siv rau rau qee yam kev ua liaj ua teb, thiab koom ua ke ntawm lwm yam tshuaj ua liaj ua teb. Nws kuj tseem siv tau los ua cov kws tua hluav taws ntawm tshav dav hlau txoj kev los tswj cov kev loj hlob yooj yim.
Textile thiab luam ntawv
Sodium thiocyanate yog ib qho tseem ceeb ntawm cov txheej txheem ntawm kev kos duab polyacrylonitrile fibers. Hauv cov txheej txheem ntau lawm ntawm polyacrylonitrile fibers, cov tshuaj no tuaj yeem yaj polyacrylonitrile monomers lossis polymers los ua cov kev daws teeb meem. Qhov kev daws teeb meem no yog txau thiab muaj kev sib raug zoo los ntawm cov cuab yeej dhau los ntawm kev kiv cov khoom siv, yog li tau polyacrylonitrile fibers. Lub solubility thiab spinning kev ua tau zoo ntawm cov tshuaj uas nws ua rau lub luag haujlwm tseem ceeb hauv kev tsim cov polyacrylonitrile fibers. Nws tuaj yeem siv los ua cov xim diffusion tus neeg sawv cev los pab cov xim diffuse tusyees heev hauv cov fiber. Thaum lub sij hawm luam ntawv thiab zas xim, tuag yuav tsum nkag mus rau hauv cov fibers thiab daim ntawv cog lus nrog lawv los ua ntev}} kav xim. Cov tshuaj no tuaj yeem txhawb cov diffusion thiab nkag mus ntawm dyes, yog li kev txhim kho kev luam ntawv thiab zas xim ua haujlwm thiab cov xim sib dhos. Nws kuj tseem tuaj yeem siv ncaj qha los ua cov ntaub tuab tus neeg sawv cev kom ntxiv xim rau cov ntawv nyeem. Los ntawm kev sib txuas nrog DYES, cov xim tuaj yeem ruaj khov rau ntawm cov fibers, txhim kho cov xim nrawm thiab ua kom pom tseeb. Nws tseem muaj ntau cov ntawv thov hauv cov kev lag luam textile, xws li tau siv ua ib hom huab cua thiab tsim cov txheej txheem acrylonitrile fiber ntau txheej txheem, thiab raws li kev txo cov zas. Cov ntawv thov no txuas ntxiv nthuav lawv cov kev siv hauv Textile thiab luam ntawv thiab dyeing kev lag luam.
Cov tshuaj tiv thaiv tsis zoo
Sodium Thiocyanate dawsYog ib qho kev daws teeb meem inorganic nrog cov kuab lom uas tuaj yeem ua kom muaj kev phom sij uas tuaj yeem ua kom muaj kev phom sij los ntawm kev sib chwv hauv qhov ncauj, tawv nqaij.
