Ukusetshenziswa kwe-calcium nitrite kukhonkolo usimende

Izakhiwo eziyisisekelo ze-calcium nitrite

I-Calcium nitrite (Ca (NO2) 2) iyikristale eqinile emhlophe noma ephuzi kancane enezinto ezincibilikayo kanye nezindawo zokuncibilika emanzini. Ukuminyana kwayo okuhlobene kungu-2.53 ku-30 ​​℃, kanye no-2.23 ku-34 ℃ (isimo esingenamanzi). Iphuzu elincibilikayo le-calcium nitrite liyi-100 ℃, lapho kuzolahleka khona i-molecule eyodwa yamanzi ayikristalu. Isenzo salesi sakhiwo kukhonkolo sibangelwa ikakhulukazi izakhiwo zayo ze-oxidizing nokunciphisa, kanye nokuxhumana kwayo nezinye izinhlanganisela kusimende.

 

Indlela yokusebenza kwe-calcium nitrite kukhonkolo kasimende ingaqondwa kulezi zici ezilandelayo:

 

Khuthaza ukuqina kukasimende

 

I-calcium nitrite, njenge-accelerator eqinisayo, ingasheshisa ukusabela kwe-hydration kasimende futhi ifinyeze isikhathi sokusetha sikakhonkolo. Lokhu kungenxa yokuthi i-nitrite ion ku-calcium nitrite ingasabela nge-silicate futhi i-aluminate kusimende ukuze yakhe ijeli ye-CSH eyengeziwe neminye imikhiqizo ye-hydration, ngaleyo ndlela ithuthukise amandla nokuqina kokhonkolo.

 

Ukusebenza kwe-antifreeze

 

Ezindaweni ezisezingeni eliphansi lokushisa, inqubo yokuqina kokhonkolo ingathinteka kakhulu, futhi ingase iholele nasekulimaleni kwesakhiwo sokhonkolo. Ukwengezwa kwe-calcium nitrite kungathuthukisa ukumelana nesithwathwa sikakhonkolo, okuvumela ukuba kugcinwe inqubo evamile yokuqina ngaphansi kwezimo eziphansi zokushisa. Lokhu kungenxa yokuthi i-calcium nitrite ingakwazi ukwehlisa indawo yokuqandisa ngaphakathi kukakhonkolo futhi inciphise umphumela obhubhisayo wamakristalu eqhwa ku-matrix kasimende.

 

Umphumela wokuvimbela ukugqwala

 

Ukugqwala kwemigoqo yensimbi kungenye yezinto eziyinhloko ezithinta ukuqina kukakhonkolo. Umphumela wokugqwala we-calcium nitrite kukhonkolo ubonakala ngokuyinhloko ekhonweni layo lokwenza ifilimu evikelayo ebusweni bezinsimbi zensimbi, ukuvimbela amanzi nomoya-mpilo ukuthi ungahlangani nezinsimbi zensimbi, ngaleyo ndlela wehlise ijubane noma uvimbele inqubo yokugqwala yezinsimbi zensimbi.

 

Izinzuzo ze-calcium nitrite

 

Ukuthuthukisa ukusebenza kokhonkolo

 

I-calcium nitrite ingathuthukisa ngokuphawulekayo amandla okuqala nokugcina kakhonkolo, ithuthukise ukumelana nesithwathwa nokuqina kwayo, futhi ngaleyo ndlela yandise impilo yesevisi yezakhiwo zikakhonkolo.

 

Ihambisana nemvelo

 

I-calcium nitrite, njengenhlanganisela ye-inorganic, ayifaki izinto eziphilayo eziyingozi futhi inomthelela omncane emvelweni. Ngaleso sikhathi, inqubo yokukhiqiza i-calcium nitrite ilula futhi ukusetshenziswa kwezinsiza kuphansi.

 

izinzuzo zezomnotho

 

Ukusebenzisa i-calcium nitrite njengenhlanganisela yekhonkrithi kunganciphisa ngempumelelo izindleko zokulungisa nokushintsha izakhiwo zekhonkrithi, futhi kunezinzuzo ezinhle zezomnotho ngokuhamba kwesikhathi.

 

Amacala Okusebenza Kobunjiniyela Bangempela

 

Kumaphrojekthi wobunjiniyela asebenzayo, ukusetshenziswa kwe-calcium nitrite kuzuze imiphumela ebalulekile. Isibonelo, ekwakhiweni kwamabhuloho, imigwaqo, nezinye izingqalasizinda ezindaweni ezibandayo, ukusetshenziswa kwe-calcium nitrite kuqinisekisa ukuqina okuvamile kanye nokuzinza kwesikhathi eside kukakhonkolo ngaphansi kwezimo eziphansi zokushisa. Ngaphezu kwalokho, ukumelana nokugqwala kwe-calcium nitrite kubaluleke kakhulu ekuvikeleni izakhiwo zikakhonkolo eziqinisiwe ekugqwaleni kubunjiniyela basolwandle kanye nezindawo zamakhemikhali.

 

Isiphetho

 

I-calcium nitrite, njengengxube kakhonkolo esebenzayo, idlala indima ebalulekile ekuthuthukiseni ukusebenza kwekhonkrithi, ekweluleni ukuphila kwesakhiwo, kanye nokunciphisa izindleko zokuyilungisa. Ngokuthuthuka okuqhubekayo kwezidingo zokusebenza okukhonkolo, ukusetshenziswa kwe-calcium nitrite kuzokwanda kakhulu. Ucwaningo lwesikhathi esizayo kufanele luqhubeke luhlola indlela yokusebenza kwe-calcium nitrite kanye nendlela yokusebenzisa kahle le nto ukukhuthaza ukuthuthukiswa okuqhubekayo kobuchwepheshe obuphathekayo.
