Ukusetshenziswa okuyinhloko kwe-caustic soda ekukhiqizeni izinto zokusetshenziswa zamakhemikhali

Ukusetshenziswa okuyinhloko kwe-caustic soda ekukhiqizeni izinto zokusetshenziswa zamakhemikhali

 

1. Ukukhiqiza izinto zokuhlanza nensipho

 

I-Caustic soda iwumthombo obalulekile wokukhiqiza izinto zokuhlanza nensipho. Ekuphenduleni kwe-saponification, uwoyela uhlangana ne-caustic soda ukukhiqiza insipho ne-glycerol. Ngaphezu kwalokho, i-caustic soda iphinde isetshenziselwe ukulungisa inani le-pH lezinto zokuhlanza nokuthuthukisa umphumela wazo wokuhlanza.

 

2. Ukukhiqizwa kwamapulasitiki kanye nemicu yokwenziwa

 

I-Caustic soda nayo inezinhlelo zokusebenza ezibalulekile ekukhiqizeni amapulasitiki kanye nemicu yokwenziwa. Isibonelo, ekukhiqizeni i-polyvinyl chloride (PVC), i-caustic soda isetshenziselwa ukwenza i-vinyl chloride monomers. Ekukhiqizeni imicu yokwenziwa efana ne-polyester nenayiloni, i-caustic soda isetshenziselwa ukusabela kwe-condensation.

 

3. Ukucubungula irabha

 

I-Caustic soda isetshenziswa enqubweni ye-vulcanization yokucubungula irabha, engathuthukisa izakhiwo ezingokomzimba zenjoloba, iyenze iqine futhi inwebeke.

 

4. Ukuhlanganiswa kwamakhemikhali

 

I-Caustic soda isebenza njenge-alkaline catalyst enamandla noma i-reaction medium ezinqubweni eziningi zokuhlanganiswa kwamakhemikhali. Ngokwesibonelo, ekukhiqizweni kwezidakamizwa ezithile, odayi, nezibulala-zinambuzane, i-caustic soda iyimpahla eluhlaza ebaluleke kakhulu.

 

Indlela yokusebenza ye-caustic soda

 

Indlela yokusebenza ye-caustic soda ibonakala ikakhulukazi kulezi zici ezilandelayo:

 

1. I-Acid alkali neutralization

 

Njenge-alkali enamandla, i-caustic soda inganciphisa nge-asidi ukukhiqiza amanzi nosawoti. Lesi sakhiwo senza i-caustic soda ibe usizo kakhulu ekulawuleni i-pH nokudala izindawo ezine-alkaline.

 

2. Ukusabela kwe-saponification

 

I-alkali ihlangana namafutha ukuze ikhiqize insipho ne-glycerol, okuyisisekelo sokukhiqiza insipho nezinto zokuhlanza.

 

3. I-Catalysis

 

I-Caustic soda isebenza njenge-catalyst ekuphenduleni kwamakhemikhali amaningi, isheshisa inqubekelaphambili yokusabela futhi ithuthukise isivuno somkhiqizo.

 

Umthelela we-caustic soda endaweni ezungezile

 

Ukukhiqizwa nokusetshenziswa kwe-caustic soda kunomthelela othile emvelweni. Imikhiqizo eyingozi efana ne-chlorine negesi ye-hydrogen ingase ikhiqizwe phakathi nenqubo yokukhiqiza i-caustic soda, edinga ukuphathwa ngendlela efanele. Ngaphezu kwalokho, uma amanzi angcolile akhiqizwa ukusetshenziswa kwe-caustic soda ekhishwa ngokuqondile ngaphandle kokwelashwa, kuzodala ukungcola emzimbeni wamanzi. Ngakho-ke, amabhizinisi amakhemikhali kudingeka athathe izinyathelo ezisebenzayo zokuhlanza amanzi angcolile ukuze anciphise umthelela wawo endaweni ezungezile.

 

Amathrendi entuthuko yesikhathi esizayo

 

Ngokukhula kwesidingo sokuvikelwa kwemvelo kanye nentuthuko esimeme, imboni yamakhemikhali ifuna izindlela zokukhiqiza ezivumelana nemvelo. Lokhu kuhlanganisa:

 

1. Ukuthuthukisa inqubo

 

Ngokulungiselela inqubo, ukusetshenziswa kwe-caustic soda kuyehla, futhi ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo kuyathuthukiswa.

 

2. Umnotho oyindilinga

 

Gqugquzela ukugaywa kabusha kwe-caustic soda, unciphise ukusetshenziswa kwezinsiza kanye nokungcoliswa kwemvelo.

 

3. Ezinye izinto zokusetshenziswa

 

Yakha futhi usebenzise amanye amakhemikhali angavumelani nemvelo ukuze unciphise ukuthembela ku-caustic soda futhi unciphise izingozi zemvelo phakathi nenqubo yokukhiqiza.

 

i-epilogue

 

Njengempahla eluhlaza yamakhemikhali, i-caustic soda idlala indima ebalulekile ekukhiqizeni imikhiqizo yamakhemikhali. Kodwa-ke, ukusetshenziswa kwe-caustic soda kuletha nezinkinga zemvelo ezidinga ukuxazululwa ngokusungula izinto ezintsha zobuchwepheshe kanye nokuphatha kahle. Ngokuzayo, imboni yamakhemikhali izoqhubeka nokuhlola izinqubo zokukhiqiza ezinobungani nemvelo ukuze kuzuzwe intuthuko esimeme.
