Glacial Acetic Acid 99.8%, Npaj Txhij Rau Kev Xa Khoom ~

Daim Ntawv Thov

Cov Ntawv Thov Kev Lag Luam
1. Acetic acid yog ib yam khoom siv tshuaj lom neeg thiab yog ib qho tseem ceeb tshaj plaws ntawm cov organic acids. Feem ntau siv rau kev tsim cov acetic anhydride, acetate thiab cellulose acetate. Polyvinyl acetate tuaj yeem ua rau cov yeeb yaj kiab thiab cov nplaum, thiab tseem yog cov khoom siv raw rau cov fiber vinylon. Cellulose acetate yog siv los ua rayon thiab zaj duab xis.

2. Acetate ester uas tsim los ntawm cov cawv qis dua yog cov kuab tshuaj zoo heev thiab siv dav hauv kev lag luam pleev xim. Vim tias acetic acid yaj feem ntau cov organic matter, acetic acid kuj yog cov kuab tshuaj organic uas siv ntau (piv txwv li, siv rau hauv kev oxidation ntawm paraxylene los tsim terephthalic acid).

3. Acetic acid siv tau rau hauv qee cov tshuaj pickling thiab polishing, ua ib qho buffer hauv cov tshuaj uas tsis muaj zog acidic (xws li zinc plating, tshuaj nickel plating), ua ib qho additive hauv semi-bright nickel plating electrolyte, thiab hauv passivation ntawm zinc thiab cadmium. Cov tshuaj no tuaj yeem txhim kho lub zog khi ntawm zaj duab xis passivation thiab feem ntau siv los kho pH ntawm cov tshuaj plating uas tsis muaj zog acidic.

4. Siv los tsim cov acetate, xws li cov ntsev ntawm manganese, sodium, lead, txhuas, zinc, cobalt thiab lwm yam hlau, uas yog siv dav ua cov catalysts thiab cov khoom ntxiv hauv kev lag luam dyeing ntaub thiab tawv tanning; lead acetate yog lead dawb hauv xim pleev xim; Lead tetraacetate yog cov organic synthesis reagent (piv txwv li, lead tetraacetate tuaj yeem siv ua cov tshuaj oxidant muaj zog, muab cov pab pawg acetoxy, thiab npaj cov organic lead compounds, thiab lwm yam).

5. Acetic acid kuj tseem siv tau ua cov tshuaj reagents analytical, organic synthesis, synthesis ntawm pigments thiab pharmaceuticals.

Cov Ntawv Thov Khoom Noj
Hauv kev lag luam khoom noj, acetic acid siv ua acidifier, tsw qab thiab txuj lom. Thaum ua cov kua txiv hmab txiv ntoo synthetic, dilute acetic acid nrog dej rau 4-5% thiab ntxiv ntau yam tsw qab. Cov saj zoo ib yam li cov kua txiv hmab txiv ntoo ua los ntawm cawv, thiab lub sijhawm tsim khoom luv luv thiab tus nqi qis. Pheej yig. Ua ib qho tshuaj qaub, nws tuaj yeem siv rau hauv cov khoom sib xyaw ua ke los npaj cov kua txiv hmab txiv ntoo, cov khoom noj hauv qab, jelly thiab cheese. Nws tuaj yeem siv rau hauv qhov ntau thiab tsawg raws li qhov xav tau ntawm kev tsim khoom. Nws kuj tseem tuaj yeem siv ua cov khoom qab zib rau Quxiang cawv, nrog rau qhov ntau npaum li cas ntawm 0.1 txog 0.3 g / kg.
