Nyob rau hauv xyoo tas los no, methamphetamine yog qhov teeb meem.Cov neeg tsim khoom lag luam thiab cov chaw tsim khoom hauv ntau lub lag luam thiab thaj chaw tau pib yuav cov tshuaj methamphetamine ntau, uas tau ua rau kev lag luam ntawm methamphetamine sai sai thiab nthuav dav.
Raws li ib tug fatty acid uas muaj nyob rau hauv cov xwm, lyceine tsis tau tsuas yog muaj kev lag luam loj heev, tab sis kuj muaj cov organic compound nrog qaub thiab irritating tsw.
Muaj ntau tus neeg xav tau cov tshuaj methamphetamine vim tias muaj ntau thiab siv ntau yam tshuaj methamphetamine, thiab nws kuj yog qhov kev xaiv zoo tshaj plaws hauv kev tsim khoom, kev tsim khoom thiab kev ua haujlwm hauv ntau lub teb.
Yog li lo lus nug los, kev siv cov tshuaj methamphetamine yog dab tsi?
1. Nyob rau hauv lub neej txhua hnub ntawm tsev neeg, siv nws los ua ib qho kev tshem tawm cov av;
2. Nws yog siv los ua pH ntawm kev ua zaub mov thiab kev tsim khoom;
3. Hauv kev lag luam kev lag luam tshuaj tua kab, tshuaj thiab dyes, siv nws ua cov kuab tshuaj thiab cov khoom siv raw.
Ntxiv rau cov hom phiaj saum toj no,dej khov acetic acidkuj plays ntau lub luag hauj lwm nyob rau hauv industrial teb xws li hluavtaws fiber thiab dyeing thiab weaving.
Txawm li cas los xij, txoj hauv kev zoo siab tshaj plaws yog suav cov ntawv thov ntawm cov dej khov cinemic acid hauv kev tsim cov kua txiv hmab txiv ntoo thiab cov kab mob edible:
1. Vinegar ntau lawm:
Qhov tsim nyog siv cov dej khov acetic acid hauv kev tsim cov kua txiv hmab txiv ntoo tuaj yeem tsis tsuas yog pab cov tuam txhab txo cov nqi ntawm cov kua txiv hmab txiv ntoo, tab sis kuj txhim kho qhov zoo ntawm vinegar, ua kom cov khoom tswj tau yooj yim dua, yooj yim, thiab txhim khu kev lag luam kev sib tw ntawm vinegar;
