Zvinokudhaya maasidhikuve nekuita kwakanaka mumunda wezvigadzirwa zvemaindasitiri, uye minda yakawanda yatanga kushandisa dhayi asidhi panzvimbo yeacetic acid. Nekudaro, iyo asidhi yekudhaya zvakare ine PH zvinodiwa, uye chiyero chekushandisa hachina kufanana!
Kudhaya asidhi kunonyanya kushandiswa mumicheka semvere dzemakwai, sirika uye naironi, uye inogonawo kuita basa rakakosha mukugadzirwa kwedehwe, bepa neingi. Saka nzira yekuziva sei kuenderana zvakasiyanakudhaya maasidhimumashandisirwo akasiyana?
Ndeapi mapoka ekudhaya asidhi ari kushandiswa?
1. Madhayi ane acid akasimba
Dhayi iyi ndiyo inonyanya kukosha, uye zvakare dhayi yeasidhi yekutanga, inofanana uye iri nyore kuisa ruvara pakudhaya nekuruka zvigadzirwa zvemakushe, nekuti chimiro chemolecular yerudzi urwu rwedhayi asidhi iri nyore, uye inoita kuti inzwe kushomeka.
2. Madhayi ane acidic asina simba
Kana ichienzaniswa neakasimba acidic dyeing acids, uremu hwayo hwema molecular hunowedzera uye hwakaoma, kuitira kuti kuwirirana kwemvere dzemakwai kwakakura. Paunenge uchishandisa madhayi asina simba easidhi kudhayi uye kuruka makushe, anogona kudzivirira mamorekuru emvere kusvika pamwero mukuru, kuvandudza kusimba kwawo, uye ruvara ruchataridzika zviri nani, asi kudhaya hakuna kunyanya kufanana.
3.Kudhaya asidhi
Tsvaga vamwe vanogadzira kuti vape asidhi yekudhaya se mordant yekudhaya nekuruka, inogona kuumba dhaya resimbi yakaoma pamucheka. Kunyangwe iyo nzira yekudhaya ichave yakaoma, kushandiswa kweiyi asidhi yekudhaya kunogona kuita kuti jira rirambe rinopesana nechiedza chezuva, kugeza kwakasimba uye kupesana kwekunze.
Saka nei vagadziri vakawanda vachitanga kusarudza maasidhi ekudhaya?
Vanhu vazhinji vanofunga kuti sezvo iine asidhi, ichaita kuti kukuvadza kune fiber element, uye panguva ino, asidhi yekudhaya haina kuvapo kweiyo inorganic acid, kuitira kuti cellulose irege kupera simba kana ikasangana nehydrolysis, nokudaro ichikuvadzwa, chokwadi, yakachengeteka kushandisa!
Iyo asidhi yekudhaya zvakare ine yakanaka buffer kurwisa asidhi uye base kana yashandiswa. Mushure mekushandiswa kwedhayi acid, iyo buffer PH kukosha inogona kugadziridzwa mukuita kuchengetedza kugadzikana kweiyo dhayi mhedzisiro.
Mushure mekushandiswa kwedhayi acid, inogonawo kuvandudza mugumisiro wekudhaya wejira kune imwe nhanho, uye kune zvinhu zvakadai seacetic acid, inonyanya kugadzikana kune tembiricha pakuvakwa, uye mhedzisiro iri nani kana yakashandiswa.
Kazhinji, kushandiswa kwedhayi acid kuchiri kwakawanda uye kwakakosha! Kana iwe uchida kutanga, zvinokurudzirwa kuti uwane nyanzvi uye yakavimbika mugadziri zvakananga
