Soodhaha caustic waxaa loo qaybin karaa soodhaha flake, soodhaha granular iyo soodhaha adag si waafaqsan qaabkeeda. Isticmaalka soodhaha caustic waxay ku lug leedahay meelo badan, kuwan soo socda ayaa kuu ah hordhac faahfaahsan:
1. Batroolka la safeeyey.
Ka dib markii lagu dhaqo sulfuric acid, alaabta batroolka ayaa weli ku jira maaddooyin acidic ah, kuwaas oo ay tahay in lagu dhaqo xal sodium hydroxide ka dibna lagu dhaqo biyo si loo helo alaab la safeeyey.
2.daabacaadda iyo midabaynta
Inta badan waxaa loo isticmaalaa dheeha indigo iyo midabada quinone. Habka rinjiyeynta ee dheeha vateed, xal soodhaha caustic iyo sodium hydrosulfite waa in loo isticmaalaa si loo yareeyo leuco acid, ka dibna oksaydhized xaalad asalka ah ee aan la milmi karin oo leh oksaydhiyeyaasha ka dib dheeha.
Ka dib marka dharka suufka ah lagu daaweeyo dareeraha soodhaha, shayga, dufanka, istaarijka iyo walxaha kale ee ku daboolan dharka suufka ayaa laga saari karaa, isla mar ahaantaana, dhalaalka mercerized ee dharka ayaa la kordhin karaa si rinjiyeyntu ka dhigto mid isku mid ah. .
3. Fiber-dharka
1)Textile
Cudbi iyo dharka linenka ah waxaa lagu daaweeyaa sodium hydroxide (caustic soda) oo la uruuriyay si loo hagaajiyo sifooyinka fiber-ka. Fiilooyinka ay dadku sameeyeen sida rayn, rayon, rayn, iwm, waa inta badan fiilooyinka viscose. Waxay ka samaysan yihiin cellulose (sida saxarka), sodium hydroxide, iyo carbon disulfide (CS2) sida alaabta ceeriin si ay u sameeyaan dareeraha viscose, kaas oo lagu buufiyo, oo lagu sameeyay uumi.
2). Viscose fiber
Marka hore, isticmaal 18-20% xal soodhaha caustic si aad u daadiso cellulose si aad uga dhigto alkali cellulose, ka dibna qallaji oo burburi cellulose alkali, ku dar disulfide kaarboon, ugu dambeyntii milanka sulfonate leh lye dilute si aad u hesho viscose. Ka dib shaandhaynta iyo faakiyuumka (saarida xumbooyinka hawada), waxa loo isticmaali karaa miiqinta.
4. Warqad samaynta
Alaabta ceeriin ee warqad-samaynta waa geedo alwaax ama caws, kuwaas oo ka kooban xaddi badan oo aan cellulose ahayn (lignin, xanjo, iwm.) marka lagu daro cellulose. Sodium hydroxide waxaa loo isticmaalaa sifaynta, oo kaliya marka lignin alwaax ah la saaro ayaa la heli karaa fiilooyinka. Qaybaha aan cellulose-ka ahayn waa la kala diri karaa oo la kala saari karaa iyadoo lagu darayo milan sodium hydroxide, si saxarka leh cellulose sida qaybta ugu weyn loo heli karo.
5. Ku hagaaji ciidda lime.
Carrada dhexdeeda, cimilada macdanta ayaa sidoo kale laga yaabaa inay soo saarto asiidh sababtoo ah samaynta asiidhyada organic sida maaddada dabiiciga ahi u qudhunto. Intaa waxaa dheer, isticmaalka bacriminta aan dabiiciga ahayn sida ammonium sulfate iyo ammonium chloride waxay sidoo kale ka dhigi doontaa ciidda acidic. Codsashada qadar habboon oo lime ah waxay ka takhalusi kartaa walxaha acidic ee ciidda ku jira, taasoo ka dhigaysa ciidda ku habboon koritaanka dalagga iyo kor u qaadida taranka bakteeriyada. Kordhinta Ca2 + ee carrada waxay kor u qaadi kartaa xinjirowga colloid carrada, taas oo u sahlaysa samaynta isku-darka, isla markaana waxay siin kartaa kalsiyumka loo baahan yahay koritaanka dhirta.
6. Warshadaha kiimikaad iyo kiimikooyinka reagents.
Warshadaha kiimikada, soodhaha caustic waxaa loo isticmaalaa samaynta birta sodium iyo biyaha korantada. Soodhaha caustic ama dambaska soodhaha ayaa loo isticmaalaa soo saarista milix badan oo aan organic ahayn, gaar ahaan diyaarinta milixda sodium qaarkood (sida borax, silicate sodium, phosphate sodium, dichromate sodium, sodium sulfite, iwm.). Soodhaha caustic ama dambaska soodhaha ayaa sidoo kale loo isticmaalaa isku-dhafka midabada, daroogooyinka iyo dhexdhexaadiyeyaasha organic.
7. caag, maqaar
1). Silica soo deysay
Marka hore: samee galaas biyo ah (Na2O.mSO2) adigoo ka falcelinaya sodium hydroxide leh quartz ore (SiO2)
Midda labaad: ka falcelinta galaaska biyaha leh sulfuric acid, hydrochloric acid, iyo carbon dioxide si ay u soo saarto kaarboonka madow ee degdega ah (silikon dioxide)
Silica halkan lagu sheegay ayaa ah wakiilka ugu wanaagsan ee xoojinta caag dabiici ah iyo caag synthetic ah
2). Dib u warshadaynta caag duug ah
Dib-u-warshadaynta caag duug ah, budada caagga ah ayaa lagu sii daaweeyaa xal sodium hydroxide, ka dibna waa la warshadeeyaa.
3). Haragga
Hargaha: habka dib-u-warshadaynta ee dareeraha wasakhda hargaha, dhinaca kale, inta u dhaxaysa labada tillaabo ee sodium sulfide aqueous aqueous solution qooynta iyo ku darida daawaynta qooynta budada lime ee habka balaadhinta ee hadda jirta, isticmaalka miisaanka dambaska ayaa kordhay 0.3-0.5 30% Talaabada daawaynta xalinta sodium hydroxide waxay ka dhigaysa xuubka maqaar si buuxda u balaadhiyo, buuxiyo shuruudaha geedi socodka, oo wanaajiya tayada badeecada dhammaatay.
8. Biraha, korantada
Warshadaha birta, inta badan waa lagama maarmaan in maaddooyinka firfircoon ee macdanta loo beddelo cusbada sodium ee milmay si meesha looga saaro wasakhda aan milmi karin. Sidaa darteed, inta badan waa lagama maarmaan in lagu daro dambaska soodhaha (sidoo kale waa qulqulo), mararka qaarkoodna soodhaha ayaa sidoo kale loo isticmaalaa.
9.dhinacyada kale ee doorka
1). Waxaa jira laba hawlood oo soodhaha caustic soodhaha ah ee soosaarka dhoobada. Marka hore, soodhaha caustic waxaa loo isticmaalaa sida dareere ah habka toogashada ee ceramics. Marka labaad, dusha ceramics-ka la shiday waa la xoqi doonaa ama aad u qallafsanaan doona. Ku nadiifi xal soodhaha ah Ugu dambeyntii, ka dhig dusha dhoobada mid siman.
2). Warshadaha qalabka, waxa loo isticmaalaa sida dhexdhexaadiyaha aashitada, midab-dejiyaha iyo deodorizer. Warshada xabagta waxaa loo isticmaalaa sida gelatinizer istaarijka iyo dhexdhexaadiyaha. Waxaa loo isticmaali karaa sida wakiilka diirka, wakiilka midabaynta iyo wakiilka carfiye ee liinta, fersken, iwm.
