Qhov zoo
Kev ua haujlwm thiab cov nyhuv zoo dua li lwm cov dyeing acid andglacial acetic acid.lt tsis muaj kev puas tsuaj rau cov fiber ntau, hauv dyeing da dej pHvalue yog ruaj khov.it tsis muaj kua qaub quav, sediment thiab cov teebmeem ntawm cov dej tawv, txhim kho cov xim zoo nkauj thiab qib-dyeing khoom. ntawm somedyestuff, thiab tsis muaj qhov cuam tshuam rau lub teeb xim lossis xim ceev ntawm cov khoom lag luam. Tsis tas li ntawd, tsis muaj ntxhiab tsw ntxhiab, tsis khov rau lub caij ntuj no, nyab xeeb thiab yooj yim siv.1. Kev siv glacial acetic acid hauv kev tsim cov kua txiv hmab txiv ntoo.

Nyob rau hauv xyoo tas los no, nrog kev sib tw tsis tu ncua ntawm kev lag luam kev lag luam, cov tuam ntxhab tau tsim cov khoom noj khoom haus glacial acetic acid kom txuag tau cov ntaub ntawv raw thiab txo cov nqi, thiaj li hloov cov ntaub ntawv tseem ceeb ntawm vinegar barley thiab starch. Tshwj xeeb, daim ntawv thov ntawm glacial acetic acid nyob rau hauv zus tau tej cov vinegar yog raws li nram no:

(1) Kev tsim nyog siv glacial acetic acid. Tsim nyog siv glacial acetic acid nyob rau hauv zus tau tej cov edible vinegar yuav pab kom txo tau tus nqi ntawm vinegar ntau lawm thiab txhim khu nws kev lag luam kev sib tw.

(2) Ua kom cov hydrolysis ntau lawm ntawm glacial acetic acid. Glacial acetic acid muaj lub cev muaj zog ntawm qhov kub thiab txias taw tes, yog li nws tuaj yeem yaj ncaj qha rau hauv vinegar los ntawm kev ntxiv dej, thiab muaj qhov ruaj khov zoo li vinegar.

(3) Ua tib zoo saib xyuas qhov zoo ntawm hydrolyzed glacial acetic acid. Txawm hais tias hydrolyzed glacial acetic acid tuaj yeem txuag cov nqi tsim khoom, nce nws cov txiaj ntsig kev lag luam, tab sis nyob rau hauv cov txheej txheem ntawm hydrolyzed acetic acid rau qhov feem ntawm glacial acetic acid kuj yuav tsum tau tswj nyob rau hauv ib tug kuj nruab nrab ntau yam, txwv tsis pub nws yuav cuam tshuam qhov zoo ntawm edible. vinegar, txo nws cov khoom noj muaj pes tsawg leeg, thiaj li coj qee qhov kev poob rau kev lag luam kev lag luam.

2. Daim ntawv thov ntawm glacial acetic acid nyob rau hauv zus tau tej cov edible fungi.

Raws li cov tshuaj hnyav, glacial acetic acid tuaj yeem siv tsis tau tsuas yog hauv kev tsim cov kua txiv hmab txiv ntoo, tab sis kuj tsim cov fungi. Cov ntawv thov tshwj xeeb yuav tsum muaj cov ntsiab lus hauv qab no:

(1) Kev kho cov khoom siv kab lis kev cai. Nyob rau hauv kab lis kev cai cov ntaub ntawv ntawm edible fungi, vim nws lub sij hawm cia, ib co lwm yam kab mob yuav yug me nyuam nyob rau hauv cov kab lis kev cai cov ntaub ntawv, thiab nws yog ib qho nyuaj rau tshem tawm, yog li cuam tshuam rau qhov zoo ntawm edible fungi.

(2) Qhib inoculation. Rau cultivation ntawm edible fungi, feem ntau tshwm sim nyob rau hauv lub inoculation lub thawv, tab sis vim muaj kev cuam tshuam ntawm ntau yam, cultivation ntawm edible fungi nyob rau hauv lub inoculation box, cov ciaj sia taus ntawm cultivation yog tsawg heev. Kev cog qoob loo ntawm cov kab mob uas tau noj tau nrog glacial acetic acid tuaj yeem txhim kho nws txoj kev cog qoob loo.

(3) Qhov chaw tua kab mob. Glacial acetic acid, ua cov tshuaj hnyav, kuj tuaj yeem siv los tua kab mob. Hauv kev cog qoob loo ntawm cov kab mob edible, feem ntau muaj qee cov kab mob yug me nyuam, uas yuav ua rau muaj kuab paug loj thiab nyuaj rau kev tshem tawm. Hauv cov txheej txheem, yog tias 0.5% glacial acetic acid tuaj yeem txau thiab ua kom sov fumigation, nws yuav pab txo cov kab mob thiab ua kom cov qoob loo zoo ntawm cov fungi.
