Zita remakemikari reacetic acidis acetic acid, kemikari formula CH3COOH, uye zviri mukati 99% acetic asidhi inonamirwa kuita ice chimiro pazasi 16 ° C, inozivikanwawo se glacial acetic acid. Acetic acid haina ruvara, inonyungudika mumvura, inogona kusanganiswa nemvura mune chero chikamu, inoputika, iine organic acid isina simba.
Senge organic acid, acetic acid haingo shandiswa zvakanyanya muorganic synthesis, organic makemikari indasitiri, chikafu, mishonga uye mamwe maindasitiri, asi zvakare inoshandiswa mukuwacha nekudhaya indasitiri.
Kushandiswa kweacetic acid mukuwacha nekudhaya indasitiri
01
Acid dissolving function yeacetic acid mukubvisa tsvina
Acetic acid sevhiniga yeorganic, inogona kunyungudutsa tannic acid, asidhi yemuchero uye mamwe organic acid maitiro, mavara euswa, mavara emuto (sedikita remichero, muto wevine, muto wemadomasi, muto wekunwa zvinyoro, nezvimwewo), tsvina yemushonga, chili mafuta uye mamwe mavara, aya mavara ane organic vinegar ingredients, acetic acid seanobvisa tsvina, anogona kubvisa organic acid ingredients mumarara, seye pigment ingredients mumarara, Zvino neoxidative bleaching treatment, zvose zvinogona kubviswa.
02
Acid-base neutralization yeacetic acid mukuwacha uye kudhaya indasitiri
Acetic asidhi pachayo haina kusimba asidhi uye inogona kuderedzwa nemabhesi.
(1) Mukubvisa tsvina yekemikari, kushandiswa kwenzvimbo iyi kunogona kubvisa mavara ane alkaline, akadai semavara ekofi, mavara etii, uye mamwe mavara ezvinodhaka.
(2) Iyo neutralization yeacetic acid uye alkali inogona zvakare kudzoreredza kushanduka kwembatya kunokonzerwa nerubatsiro rwealkali.
(3) Kushandiswa kweiyo acidity isina simba yeacetic acid inogonawo kukurumidza kuita bleaching yeimwe kuderedza bleach mukugadzirisa bleach, nokuti imwe bleach inoderedza inogona kukurumidza kuora pasi pemamiriro evhiniga uye kusunungura bleaching factor, saka, kugadzirisa kukosha kwePH. ye bleaching solution ine acetic acid inogona kukurumidza kuita bleaching process.
(4) Asidhi yeacetic acid inoshandiswa kugadzirisa asidhi uye alkali yemucheka wezvokupfeka, uye zvipfeko zvekupfeka zvinobatwa neasidhi, iyo inogona kudzorera hunyoro hwehupfeko.
(5) Machira eshinda yeshinda, mukuita ironing, nekuda kwekupisa kwe ironing yakakwira zvakanyanya, zvichikonzera kukuvadzwa kwemvere dzemakwai, aurora chiitiko, ine dilute acetic acid inogona kudzoreredza mvere dzemakushe, saka, acetic acid inogonawo kubata nezvipfeko. nekuda kwe ironing aurora phenomenon.
03
Kune madhayi anonyungudika nemvura ane hydroxyl uye sulfonic acid mapoka, machira efayibha ane kushomeka kwealkali resistance (yakadai sesilika, rayon, mvere dzemakwai), pasi pemamiriro evhiniga, inobatsira kune ruvara uye kugadzirisa kwemavara emafiber.
Nokudaro, dzimwe mbatya dzisina kusimba alkaline kuramba uye nyore kupera mukugadzirisa kwekugeza zvinogona kuwedzerwa kune chiduku chiduku cheacetic acid mumucheka wekuchenesa kugadzirisa ruvara rwezvipfeko.
Kubva pakuona uku, acetic acid inoshandiswa zvakanyanya muindasitiri yekugeza uye kudhaya, asi mukuita kwekushandisa kunofanirwawo kuterera kune zvinotevera nyaya.
Kune machira ane acetic acid fibers, paunenge uchishandisa acetic acid kubvisa tsvina, iwe unofanirwa kunyatsochenjerera kuti uteerere kuacetic acid concentration haina kunyanya kukwirira. Izvi zvinodaro nekuti acetate fiber inogadzirwa nehuni, shinda yekotoni uye zvimwe cellulosic zvinhu uye acetic acid uye acetate, kushomeka kupikisa vhiniga, asidhi yakasimba inogona kukanganisa acetate fiber. Kana mavara akaiswa paacetate fiber uye machira ane acetate fibers, mapoinzi maviri anofanira kucherechedzwa:
(1) Iko kushandiswa kwakachengeteka kweacetic acid ndeye 28%.
(2) Madonhwe ebvunzo anofanirwa kugadzirwa usati washandiswa, usapisa kana washandiswa, sukurudza nekukurumidza mushure mekushandisa kana kudzikamisa nealkali isina simba.
Mazano ekushandisa acetic acid ndeaya anotevera:
(1) Dzivisa kuonana nemaziso, kana wasangana nehuwandu hweasidhi yakaviriswa, pakarepo sukurudza nemvura.
(2) Kusangana nemidziyo yesimbi kunofanira kudziviswa kuti ibudise ngura.
(3) Kudyidzana kwezvinodhaka uye alkaline zvinodhaka kuenderana zvinogona kuitika neutralization reaction uye kukundikana.
