Acid-base neutralization ya acetic acid pakuchapira ndi utoto wamakampani ndi chidwi ndikugwiritsa ntchito kwake

mawu oyamba

Dzina la mankhwala a acetic acid ndi asidi acetic, mankhwala chilinganizo CH3COOH, ndi zili 99% asidi asidi ndi crystallized mu ayezi mawonekedwe pansi 16 ° C, amatchedwanso glacial acetic acid.Acetic acidndi colorless, madzi sungunuka, akhoza miscible ndi madzi mulingo uliwonse, kosakhazikika, ndi ofooka organic asidi.

Monga asidi organic, asidi acetic osati chimagwiritsidwa ntchito kaphatikizidwe organic, organic makampani mankhwala, chakudya, mankhwala ndi mafakitale ena, komanso ntchito kuchapa ndi utoto makampani.

Kugwiritsa ntchito acetic acid pakuchapira ndi utoto

01 Kusungunuka kwa asidi acetic acid pakuchotsa banga

Acetic acidmonga organic viniga, akhoza kusungunula tannic acid, asidi zipatso ndi zina organic acid makhalidwe, udzu madontho, madontho a madzi (monga zipatso thukuta, vwende madzi, phwetekere madzi, zakumwa zoziziritsa kukhosi, etc.), madontho mankhwala, mafuta a chili ndi madontho ena, madontho awa ali ndi organic viniga zosakaniza, asidi acetic monga chochotsa banga, akhoza kuchotsa zosakaniza organic asidi mu madontho, monga zosakaniza pigment mu madontho, Ndiye ndi okosijeni blekning mankhwala, onse akhoza kuchotsedwa.

Acid-base neutralization ya acetic acid mu makina ochapira ndi utoto

Acetic acidpalokha ndi yofooka acidic ndipo imatha kuchepetsedwa ndi maziko.

(1) Pochotsa madontho a mankhwala, kugwiritsa ntchito malowa kumatha kuchotsa madontho amchere, monga madontho a khofi, madontho a tiyi, ndi madontho ena amankhwala.

(2) Kusalowerera kwa asidi ndi zamchere kungathenso kubwezeretsa kusintha kwa zovala chifukwa cha mphamvu ya alkali.

(3) Kugwiritsa ntchito asidi ofooka a asidi acetic kungathenso kufulumizitsa bleaching anachita ena kuchepetsa bleach mu ndondomeko bleach, chifukwa ena kuchepetsa bleach akhoza imathandizira kuwonongeka pansi pa vinyo wosasa zinthu ndi kumasula bleaching factor, Choncho, kusintha PH mtengo. acetic acid akhoza kufulumizitsa ntchito yoyeretsa.

(4) Asidi wa asidi acetic amagwiritsidwa ntchito pokonza asidi ndi alkali wa nsalu zobvala, ndipo zovalazo zimathandizidwa ndi asidi, zomwe zingathe kubwezeretsanso zofewa za zovala.

(5) Ubweya CHIKWANGWANI nsalu, mu ndondomeko ironing, chifukwa cha kutentha kusita ndi mkulu kwambiri, chifukwa mu kuwonongeka kwa ubweya CHIKWANGWANI, aurora chodabwitsa, ndi kuchepetsa asidi asidi akhoza kubwezeretsa ubweya CHIKWANGWANI minofu, choncho asidi asidi akhoza kuthana ndi zovala. chifukwa cha ironing aurora phenomenon.

Kwa utoto wosungunuka m'madzi wokhala ndi magulu a hydroxyl ndi sulfonic acid, nsalu za ulusi zokhala ndi kukana kwa alkali (monga silika, rayon, ubweya), pansi pa vinyo wosasa, zimathandizira kupanga utoto ndi kukonza utoto wa ulusi.

Chifukwa chake, zovala zina zokhala ndi kukana kwa alkaline komanso kutha kosavuta pakutsuka zimatha kuwonjezeredwa ndi asidi pang'ono mu chotsukira chochapa kuti chikonze mtundu wa zovala.

Kuchokera pamalingaliro awa,asidi asidiamagwiritsidwa ntchito kwambiri mumakampani ochapira ndi utoto, koma pakufunsira ayeneranso kulabadira zinthu zotsatirazi.

Kwa nsalu zomwe zimakhala ndi acetic acid fibers, mukamagwiritsa ntchito asidi acetic kuchotsa madontho, muyenera kusamala kwambiri kuti mumvetsere kuti ndende ya acetic siikwera kwambiri. Izi ndichifukwa choti ulusi wa acetate umapangidwa ndi matabwa, ubweya wa thonje ndi zinthu zina zama cellulosic ndi asidi acetic ndi acetate, kukana viniga wosasa, asidi amphamvu amatha kusokoneza CHIKWANGWANI cha acetate. Madontho akayikidwa pa ulusi wa acetate ndi nsalu zomwe zimakhala ndi ulusi wa acetate, mfundo ziwiri ziyenera kudziwidwa:

(1) Kugwiritsa ntchito bwino kwa asidi acid ndi 28%.

(2) Madontho oyesera amayenera kupangidwa musanagwiritse ntchito, osatenthetsa mukagwiritsidwa ntchito, muzimutsuka mukangogwiritsa ntchito kapena muchepetse ndi alkali yofooka.

Njira zopewera kugwiritsa ntchito acetic acid ndi izi:

(1) Pewani kuyang'ana m'maso, ngati mukukumana ndi asidi wambiri, muzimutsuka ndi madzi.

(2) Kukhudzana ndi zida zachitsulo kuyenera kupewedwa kuti apange dzimbiri.

(3) Kuyanjana kwa mankhwala ndi kuyanjana kwa mankhwala amchere kumatha kuchitika kusagwirizana ndi kulephera.

(4) Zoyipa za acetic acid zimakwiyitsa, ndipo zimawononga khungu ndi ntchofu pazambiri.
