Dab tsi yog denatured cawv

Denatured ethyl cawv yog ethanol, uas muaj cov tshwj xeeb additives (denaturing tshuaj). Tias yog vim li cas qhov kev siv ntawm xws li ib cov khoom nyob rau hauv cov zaub mov raug tshem tawm. Denatured cawv tsis tsim rau tsim cawv thiab cawv khoom.

Lub xeev cov cai

FZ ntawm kev tswj lub xeev cov khoom siv thiab cov ciaj ciam uas muaj ethanol, cawv-muaj cov khoom, suav cov cawv haus cawv ua cov khoom tsis yog khoom noj, yog tias nws muaj qee yam tshuaj, sib tov (ntawm qhov kev txiav txim ntawm lub khw).

Variants ntawm denaturing additives

Dab tsi yog tso cai rau muab tso rau hauv cov khoom no? Cov tshuaj tsis haum cawv kuj yuav muaj roj lossis kerosene, tab sis cov concentration yuav tsis tsawg tshaj li 0.5 feem pua ntawm qhov dej cawv. Tsis tas li ntawd, qhov muaj pes tsawg leeg muaj xws li bitrex (denatonium benzoate) nyob rau hauv ib qho piv txwv ntawm tsawg tshaj 0.0015% ntawm qhov ntim ntawm cov cawv cawv.

Ntawm cov kev tso cai ntxiv, uas muaj xws li cov tshuaj pleev dej cawv, txoj cai kuj hais txog crotonaldehyde hauv kev tsis txaus ntseeg.

Cov txiaj ntsig zoo li no, uas tau tso cai los ntawm tsoomfwv cov chaw khiav dej num, tsis txhob ua rau tib neeg lub cev. Lawv suav nrog cov khoom noj uas tsis yog khoom noj khoom haus los tiv thaiv cov zaub mov noj.

Yuav kom muaj txiaj ntsig zoo uas tsis suav nrog kev siv, kev tsim cov tshuaj yeeb dawb ntawm cov tshuaj yeeb dej cawv yog ua rau muaj kev qhia txog cov khoom uas nthuav dav thiab tsis txaus siab rau qhov khoom noj.

Cov nta siv nyob hauv tsev tshuaj

Txoj kev lag luam siv tshuaj lom neeg li cas yog siv li cas? Dej cawv denatured hluavtaws tsis yog tshuaj lom. Nws tso cai rau koj los tiv thaiv cov neeg ntawm lub siab xav siv nws sab hauv. Vim yog lub txiaj ntsim tshuaj ntxiv, uas ua rau nws mob siab, nws tsis tuaj yeem haus kua, tam sim ntawd ntuav tshwm sim.

Perfumery ntau lawm

Nyob rau hauv lub chaw ua khoom ntawm naj hoom ntau yam naj hoom, perfumes, colognes, kev siv cov cawv cuav haus yog kev cai thiab tso cai. Tsis txhob ntshai thaum koj pom ntawm daim ntawv qhia: "Ethyl denatured alcohol." Kev tsim cov khoom haum niaj hnub thiab cov tshuaj pleev yog los ntawm kev siv cov khoom siv no.

Muaj kev xyaum thoob ntiaj teb kev siv cov khoom zoo li no hauv kev tsim ntau hom kev xaiv tshuaj. Ntau hom, paub nyob rau hauv txawv teb chaws, kiag li txoj cai tau txais kev tshaj tawm ethanol. Yog tias koj hle tau cov kua hauv koj lub qhov ncauj, koj yuav tsum tam sim ntawd nti tawm, ces nws yuav tsis ua mob rau koj txoj kev noj qab haus huv.

Ntaus siv

Cov qhaub cij denatured yog raug mus rau txheej txheem denaturation. Methanol yog nyob rau hauv kev xav nyob rau hauv pej xeem cov tshuaj, txuam nrog kho ntawm pob qij txha. Nyob rau hauv dav dav, no tivthaiv yog muaj nyob rau hauv cov tshuaj siv los txo tawm rheumatism. Tsis tas li ntawd, qhov khoom siv nyob rau hauv Veterinary tshuaj rau disinfection.

Cov kws kho mob tau ntseeg hais tias nrog kev siv li ntawm 25 milliliters ntawm cov tshuaj cawv ntshav tau ua kom tshem tau cov teeb meem nrog pob qij txha. Nws muaj tshwj xeeb coloring additives, muab lub hwj huam ntshav hue.

Kev xaiv denaturates

Ntawm cov loj methylated dab, uas yog siv nyob rau hauv European lub teb chaws tam sim no, tej zaum nws yuav tsum tau muab sau pyrimidine bases thiab ntoo (methyl cawv).

Kuj tseem siv cov acetone, thymol, kerosene, roj ketone, formalin, ntsis. Daim ntawv teev npe no yog kho tshiab, nyob ntawm seb cov lus meej ntawm lub teb chaws. Raws li kev ntsuas kev haus cawv, feem ntau yog siv ntau yam xim. Cov khoom no yog tsim los rau cov kev siv kev ua haujlwm, cov laj thawj.

Thaum hno 5-10 ml, teeb meem loj mob tshwm sim. Yog hais tias methanol siv nyob rau hauv ib lub ntim ntawm 30 ml, lub txiaj ntsig tau ua kom muaj taus.

Raws li tus kheej ntawm tus neeg, ib qho kev sib txawv ntawm kev siv cov methylated plig tau. Lub ntsiab ntawm cov tsos mob lom yog ntuav, xeev siab. Lawv tuaj yeem tshwm sim sai sai tom qab siv, thiab tom qab ob peb teev.

Hauv cov mob hnyav tshaj plaws, qhov ntse ntse cyanosis tshwm sim, ua tsis taus pa nyuaj, qhov mem tes yuav sai dua. Cov menyuam kawm tsis tau raws li lub teeb meem. Qhov ua rau tuag taus yog qhov ua tsis taus pa.

Cov neeg txhawj xeeb uas paub meej, yws ntawm qhov mob hnyav hauv lub plab, qhov txawv ntawm cov duab. Tej zaum ib lub sij hawm txhim kho nyob rau hauv kev noj qab nyob zoo, uas yog nrog los ntawm kev kub ntxhov, qhov pib ntawm kev tuag.

Xaus

Cov kev cai nruj tau raug tsim los rau kev sim tshuaj ntxiv. Lawv yuav tsum tsis txhob cuam tshuam rau qhov zoo ntawm haus cawv, ua ib qho kev khuam siab rau lub hom phiaj ntawm qhov khoom. Thaum siv cov txheej txheem txheem - distillation, freezing, filtration - additives yuav tsum tsis txhob muab cais tawm ntawm dej cawv. Tsis tas li ntawd, cov tswv yim yuav tsum yog pheej yig.

Pib pib siv tshuaj tua kabmob thaum xyoo pua nees nkaum, sib ntaus sib tua li no nrog kev tuag ntawm vim kev quav dej caw. Nyob rau hauv lub fifties ntawm lub xyoo pua xeem, diethylphthalate tau siv ua lub ntsiab denatured. Nws tsis sawv cev rau kev noj qab haus huv, yog thaum muaj kev noj kev haus tau ua rau muaj kev cuam tshuam tsis zoo rau tus neeg lub siab.

Vim yog cov ntawv teev npe, cov tshuaj tua cawv ua rau tsis haus dej tsis tsim kev puas tsuaj rau tib neeg kev noj qab haus huv. Ntawm cov teeb meem uas tuaj yeem txuam nrog nws, ib tus tuaj yeem tsuas yog ethanol lom. Vim yog denaturation, haus cawv yog sib cais los ntawm cov khoom tsim.
