Upfu hweYuanming hunonziwo munyu weGlauber, uye zita rawo resainzi isodium sulfate. Uyu munyu usingashandiswe makemikari uri pedyo zvikuru nemakemikari emunyu wetafura.

1. Inoshandiswa sedhayi yakananga uye imwe nzira yekuwedzera simba rekugadzira donje

Pakudhaya donje nedhayi dzakananga, dhayi dzesarufa, dhayi dzevat uye dhayi dzeYindioxin, sodium sulfate inogona kushandiswa sechinhu chinokurudzira dhayi.

Madhayi aya ari nyore kunyungudika mumushonga wekudhaya wakagadzirwa, asi hazvisi nyore kudhaya machira edonje. Nekuti dhayi harisi nyore kupera, kune dhayi yakawanda yasara mumvura yetsoka.

Kuwedzerwa sodium sulfate kunogona kuderedza kunyungudika kwedhayi mumvura, nokudaro zvichiwedzera simba rekupenda kwedhayi. Nenzira iyi, huwandu hwedhayi hunogona kuderedzwa, uye ruvara rwedhayi ruchadzika.

1. Huwandu hwesodium sulfate

Zvinoenderana nesimba rekupenda redhayi rinoshandiswa uye kudzika kweruvara rwaunoda. Usawedzere zvakanyanya kana nekukurumidza, zvikasadaro dhayi iri mumushonga wedhayi ichakonzera mavanga edhayi pamusoro pejira.

2. Pakudhaya jira redonje

Upfu hweYuanming hunowanzo wedzerwa muzvikamu mumatanho echitatu kusvika echina. Nekuti mushonga wedhayi wakakora kwazvo usati wadhayiwa, kana ukawedzerwa nekukurumidza, dhayi ichadhayiwa pafayibha nekukurumidza uye zviri nyore kugadzira kusaenzana, saka idhayire kwechinguva wozoiisa. Zvakakodzera.

3. Sodium sulfate usati washandisa

Upfu hweYuanming hunofanira kudzika zvizere nemvura usati washandisa, uye huseferwe usati wawedzerwa mubhavhu rekudhaya. Zvinonyanya kukosha kusanganisa bhavhu rekudhaya woriisa zvishoma nezvishoma kudzivirira bhavhu rekudhaya zvishoma kuti risabatane nehuwandu hwakawanda hweaccelerant zvoita kuti dhayi ive nemunyu. Ongorora basa.

4. Sodium sulfate nemunyu ndizvo zvinhu zvinonyanya kushandiswa pakudhaya

Maitiro ekugadzira akaratidza kuti mukudhaya zvakananga, kushandisa sodium sulfate sechinhu chinokurumidzisa dhayi kunogona kuwana ruvara rwakajeka. Mhedzisiro yekushandisa munyu wetafura haina kunaka, izvo zvine chekuita nekuchena kwemunyu wetafura. Kuwedzera kune akawanda ma calcium ne magnesium ions, munyu weindasitiri unewo ma iron ions. Mamwe madhayi anokanganiswa zvakanyanya nema iron ions (akadai se direct turquoise blue GL, nezvimwewo) anoshandisa munyu semushonga unokurumidzisa dhayi, izvo zvinoita kuti ruvara ruve grey.

5. Vamwe vanhu vanofunga kuti mutengo wemunyu wetafura wakachipa

Vamwe vanhu vanofunga kuti mutengo wemunyu wetafura wakachipa, uye munyu wetafura unogona kushandiswa kutsiva upfu hweYuanming. Zvisinei, zviri nani kushandisa upfu hweYuanming kuti uwane ruvara rwakareruka pane munyu wetafura, uye kuti uwane ruvara rwakasviba, munyu wetafura uri nani. Chero chakakodzera, chinofanira kushandiswa mushure mekuyedzwa.

6. Hukama huripo pakati pe sodium sulfate nehuwandu hwemunyu

Hukama huripo pakati pekushandiswa kwe sodium sulfate nemunyu ndehunotevera:

Zvikamu zvitanhatu zveNa2SO4=zvikamu zvishanu zveNaCl

Zvikamu gumi nezviviri zvehydrate Na2SO4·10H20=zvikamu zvishanu zveNaCl

2. Inoshandiswa semushonga wekudhaya zvakananga uye kudhaya sirika

Kushandiswa kwedhayi dzakananga pamapuroteni kunonyanya kushandiswa pakudhaya sirika, uye kukurumidza kudhaya kunowanikwa kuri nani pane kwedhayi dzine acid yakawanda. Mamwe madhayi akananga anogonawo kubudiswa zvakanaka, saka anowanzo shandiswa pakuburitsa ruvara rwevhu pakudhinda machira esirika.

Kudhaya sirika zvakananga kunowanzowedzerawo sodium sulfate shoma, asi basa resodium sulfate rakasiyana nerekudhaya donje. Rinoshanda chete sechinhu chinodhaya zvishoma nezvishoma.

Cherechedza:
1. Kudhaya sirika nedhayi dzakananga. Mushure mekunge sodium sulfate yawedzerwa, kudhaya kunononoka kunoitika seizvi:

Dhayi yakananga R SO3Na inopatsanurwa kuita sodium ion Na+ uye pigment anion R SO3- mumvura, sezvakaratidzwa mufomura inotevera: RSO3Na (miseve yeinterconversion iri mumabhureki) Na+ R SO3- yuanming powder Na2SO4 inopatsanurwa kuita sodium ion Na+ uye sulfate ion SO4- mumvura -, fomura inotevera: Na2SO4 (miseve yeinterconversion iri mumabhureki) 2Na+ RSO4–Mubhavhu rekudhaya, dhayi anion R SO3- inogona kudhaya sirika zvakananga. Kana sodium sulfate yawedzerwa, inopatsanurwa kuti ibudise sodium ion Na+, Kupatsanurwa kwedhayi kunokanganiswa nemaion sodium; kureva kuti, nekuda kwehukama hwe equilibrium hwe post-ion reaction, inokanganiswa neNa+ common ion guilt, iyo inoderedza kupatsanurwa kwedhayi, saka kudhaya sirika kunononoka. Mhedzisiro yekudhaya.

2. Pamachira akadhayiwa nedhayi dzakananga, kazhinji shandisai fixing agent Y kana fixing agent M (inenge 3~5g/l, 30% acetic acid 1~2g/l, tembiricha 60℃) kwemaminitsi makumi matatu kuti chigadzirwa chapera chiwedzere kunaka kweruvara.

4. Inoshandiswa senzira yekudzivirira ruvara rwevhu pakukwesha machira esiriki akadhindwa uye akapendwa

Pakukwesha machira esiriki achidhindwa kana kudhayiwa, dhayi inogona kubviswa, kuitira kuti isvibise ruvara rwevhu kana mamwe machira akabatana. Kana sodium sulfate ikawedzerwa, kunyungudika kwedhayi kunogona kuderedzwa, saka hapana njodzi yekubviswa kwedhayi uye kusvibisa ruvara rwevhu. Kumusoro.
