Indima ye-glacial acetic acid ekuhlambeni nasekudayweni kwelaphu

Indima ye-glacial acetic acid kwishishini lokuhlamba impahla

1. Umsebenzi wokunyibilikisa i-asidi ekususweni kwamabala
I-asidi ye-acetic njengeviniga yendalo, inokunyibilikisa i-asidi ye-tannic, i-asidi yeziqhamo kunye nezinye iimpawu ze-asidi yendalo, amabala engca, amabala ejusi (njengomjukujelwa weziqhamo, ijusi ye-melon, ijusi yetumato, ijusi yesiselo esibandayo, njl.njl.), amabala amayeza, ioyile yetshili kunye namanye amabala, la mabala aqulethe izithako zeviniga yendalo, i-asidi ye-acetic njengesusa amabala, inokususa izithako ze-asidi yendalo kumabala, njengezithako zepigment kumabala, Emva koko ngonyango lwe-oxidative bleaching, konke kunokususwa. Ngaphezu koko, xa uhlamba iimpahla ezinzima, rhoqo ngenxa yokuba ukuhlamba kungaphelelanga ngokwaneleyo, impahla iya koma okanye irhangqe emva kokuba yomile. Ukuba ayinzima kakhulu, inokutshizwa ngamanzi ane-asidi ye-acetic okanye isuswe ngetawuli ngamanzi e-asidi ye-acetic ukususa amabala okomisa kunye namabala erhangqe.

2. Nciphisa intsalela ye-alkali
I-acetic acid ngokwayo ayina-asidi kangako kwaye ingasetyenziswa xa isetyenziswa iziseko.
(1) Ekususeni amabala eekhemikhali, ukusetyenziswa kwale mpawu kunokususa amabala e-alkaline, afana namabala ekofu, amabala eti, kunye namabala athile eziyobisi.
(2) Ukungaguquguquki kwe-acetic acid kunye ne-alkali kunokubuyisela umbala weempahla obangelwa yimpembelelo ye-alkali.
(3) Ukusetyenziswa kwe-asidi ebuthathaka ye-acetic acid kunokukhawulezisa ukusabela kwe-bleach ethile yokunciphisa kwinkqubo ye-bleach, kuba i-bleach ethile yokunciphisa inokukhawulezisa ukubola phantsi kweemeko zeviniga kwaye ikhulule i-bleaching factor, ngoko ke, ukulungisa ixabiso le-PH lesisombululo se-bleaching nge-acetic acid kunokukhawulezisa inkqubo ye-bleach.
(4) I-asidi ye-acetic acid isetyenziselwa ukulungisa i-asidi kunye ne-alkali yelaphu lempahla, kwaye impahla yempahla iphathwa nge-asidi, enokubuyisela imeko ethambileyo yempahla yempahla.
(5) Ilaphu lefayibha yoboya, kwinkqubo yoku-ayina, ngenxa yokuba ubushushu boku-ayina buphezulu kakhulu, nto leyo ebangela umonakalo kwifayibha yoboya, nto leyo ebangela ukukhanya, xa i-acetic acid inyibilikisiwe, inokubuyisela izicubu zefayibha yoboya, ngoko ke, i-acetic acid ingasetyenziselwa ukujongana nokukhanya okubangelwa kuku-ayina.

3. umbala oqinileyo ukuthintela ukufiphala
Ezinye iimpahla ziphelelwe ngamandla, iimpahla zisandula ukufakwa kwisepha, inani elikhulu leedayi liya kunyibilika, kunzima ukuqhubeka nokuhlamba. I-Acetic acid ingasetyenziselwa unyango lokuphakamisa idayi. Okokuqala, musa ukuyeka ukuhlamba, kwaye ugqibezele ukuhlamba iimpahla ngokukhawuleza. Emva kokukhupha impahla, musa ukuthulula amanzi anedayi, yongeza ngoko nangoko isixa esifanelekileyo se-glacial acetic acid, emva nje kokuvuselela impahla emanzini, yintywilisele imizuzu eli-10-20, kwaye ujike rhoqo ngexesha lokuyifunxa ukuze uthintele ukungalingani. Emva konyango, idayi emanzini "iyaphakanyiswa" kwimpahla. Emva koko, qhubeka uhlamba ngamanzi ane-acetic acid, ukuphelelwa ngamanzi emzimbeni kwaye wome. Oku akunakuphelisa kuphela ukufiphala kwempahla, kodwa kwenze nombala wempahla ube mhle njengomtsha. Ingakumbi kwilaphu lesilika, i-ice acetic acid isetyenziselwa ukulungisa umbala, ukukhusela i-fiber yomphezulu wesilika, ukunciphisa ukufiphala kwayo, kunye nokwandisa ubomi bokunxiba.

Indima ye-glacial acetic acid ekuprintweni nasekudayweni kwelaphu
1. kwinkqubo yokudaya, i-glacial acetic acid inokudlala indima ekulungiseni idayi. Ngexesha lenkqubo yokudaya, idayi kufuneka isebenzise iikhemikhali kunye neemolekyuli zefayibha ukuze inamathele ngokuqinileyo kwifayibha. Njenge-arhente yokuthomalalisa, i-glacial acetic acid inokulungisa ixabiso le-pH phakathi kwedayi kunye nefayibha, ukuze ibe kwimeko entle yokusabela.
2. I-glacial acetic acid inokwenza i-complex ezinzileyo ngeedayi, inyusa amandla okubopha eemolekyuli zedayi kunye neemolekyuli zefayibha, ngaloo ndlela iphucula ukuqina kunye nokuqina kokudaya.
3. Ekugqityweni kwelaphu, ukongeza ubungakanani obufanelekileyo be-glacial acetic acid kunokwenza iibhondi ze-ester ezingaphezulu phakathi kweemolekyuli zefayibha, ngaloo ndlela kuphucula ukumelana nemibimbi kunye nokumelana nokuhlanjwa kwelaphu.

Ityala lesicelo se-glacial acetic acid kushishino lokuprinta kunye nokudaya impahla
1. Ukudaya umqhaphu
Kwinkqubo yokudaya ikotoni, i-glacial acetic acid isetyenziswa njengomncedisi wokunceda idayi ingene kwifayibha yekotoni ngcono kwaye iphucule isiphumo sokudaya. Ukongeza, ingasetyenziselwa ukulungisa ixabiso le-pH yesisombululo sedayi ukukhuthaza indibaniselwano yedayi kunye nefayibha yekotoni.
2. Ukudaya uboya
Iifayibha zoboya zinomaleko wegrisi kumphezulu, nto leyo enzima ukuba iidayi zingene. Kwimeko enjalo, i-glacial acetic acid isetyenziswa njengesixhobo sokuncedisa ukususa igrisi kumphezulu wefayibha yoboya kunye nokuphucula ukungena nokuphuma kwedayi.
3. Ukudaya ipolyester
I-Polyester yifayibha eyenziweyo engayingenisi amanzi kwaye kunzima ukuyifaka kwiidayi. Ukuze kuphuculwe isiphumo sokudaya se-polyester, i-glacial acetic acid isetyenziswa njengesongezelelo ukunceda idayi ingene kwifayibha ngcono.
4. Ukudaya isilika
Isilika lilaphu elithambileyo elinobuthathaka kakhulu kutshintsho lobushushu kunye ne-pH. Kwinkqubo yokudaya isilika, i-glacial acetic acid isetyenziswa njengomncedisi wokulawula ubushushu kunye nexabiso le-pH yesisombululo sokudaya ukuqinisekisa isiphumo sokudaya kunye nomgangatho.
5. Inkqubo yokuprinta
Kwinkqubo yokuprinta, i-glacial acetic acid isetyenziswa njenge-arhente encedisayo ye-acid printing paste ukuphucula isiphumo sokuprinta kunye nokuchaneka. Ukongeza, ingasetyenziselwa ukulungisa ixabiso le-pH ye-printing paste ukukhuthaza indibaniselwano ye-printing paste kunye ne-fiber.
