Ukuhlaziywa okusha kwesimiso sokutholwa kokushisa kwe-silicon Carbide graphible ecashile

1. Izakhiwo ezibonakalayo nesakhiwo

I-Silicon Carbide Graphible ecashile kuhlanjululwa kusuka ezintweni ezifana ne-graphite kanye ne-silicon carbide ngokusebenzisa izinqubo eziyinkimbinkimbi, kuhlanganisa izakhiwo zazo ezinhle kakhulu. Izakhiwo eziphambili zegraphite zifaka:

 

Ukuqhutshwa kukagesi nokwe-Thermal: I-Graphite inokuqonda okuhle kagesi nokwenziwa okushisayo, okuvumela ukudlulisa ngokushesha ukushisa nokunciphisa ukulahleka kwamandla ezindaweni eziphakeme zokushisa.

Ukuqina kwamakhemikhali: I-Graphite ihlala iqinile futhi imelana nokusabela kwamakhemikhali ezindaweni eziningi ze-acidic ne-alkaline.

Ukumelana nokushisa okuphezulu

Izakhiwo eziphambili ze-Silicon Carbide zifaka:

 

Amandla okwenziwa ngomshini: I-Silicon Carbide inobulukhuni obuphezulu namandla emishini, futhi iyamelana nokugqoka okwenziwe ngomshini kanye nomthelela.

Ukuphikiswa kokugqwala: kukhombisa ukumelana okuhle kakhulu kokugqwala kumazinga okushisa aphezulu nasekulimaleni umoya.

Ukuqina okushisayo: I-Silicon Carbide ingagcina izakhiwo ezizinzile zamakhemikhali nezingokomzimba ezindaweni eziphakeme zokushisa.

Ukuhlanganiswa kwalezi zinto ezimbili kudalaI-Silicon Carbide Graphible ecashileI-S, enezinto zokumelana nokushisa okuphezulu, ukuqhutshwa okuhle kakhulu okushisayo kanye nokuqina okuhle kwamakhemikhali, okwenza balungele izinhlelo zokusebenza zokushisa eziphakeme.

 

2. Ukusabela kwamakhemikhali kanye nendlela e-endothermic

I-Silicon Carbide Graphible ecashile Uthola uchungechunge lokuphendula kwamakhemikhali endaweni yokushisa ephezulu, engagcini nje kuphela ukusebenza kwezinto ezisebenzayo, kepha futhi ingumthombo obalulekile wokusebenza kwayo kokutholwa kokushisa. Ukusabela okukhulu kwamakhemikhali kufaka:

 

Ukusabela kabusha kwe-Redox: I-Metal Oxide iphendula nge-ejenti encishisiwe (efana nekhabhoni) ebekiwe, ekhipha inani elikhulu lokushisa. Isibonelo, i-Iron Oxide isabela ngekhabhoni ukuze i-Iron ne-Carbon Dioxide:

 

FE2O3 + 3C→2fe + 3co

Ukushisa okukhishwe yilokhu kusabela kudonswa yinto ebekiwe, ekhulisa izinga lokushisa layo eliphelele.

 

Ukusabela kwePyrolysis: Emazingeni okushisa aphezulu, izinto ezithile zibhekene nokuvundwa kokuvundwa okukhiqiza ama-molecule amancane nokukhipha ukushisa. Isibonelo, i-calcium carbonate ibola ngamazinga okushisa aphezulu ukukhiqiza i-calcium oxide nekhabhoni diokdide:

 

Ukhekhi→I-CAO + CO2

Lokhu kusabela kwe-pyrolysis nakho kukhipha ukushisa, okudonswa yi-ebekiwe.

 

Ukusabela kweSteam: Umphunga wamanzi uphendula ngekhabhoni emazingeni okushisa aphezulu ukukhiqiza i-hydrogen nekhabhoni monoxide:

 

H2o + c→H2 + co

Ukushisa okukhishwe yilokhu kusabela nakho kusetshenziswa yi-Elecal.

 

Ukushisa okukhiqizwe yilezi zinto zokusabela kwamakhemikhali kuyindlela ebalulekile yeI-Silicon Carbide Graphible ecashile Ukudonsa ukushisa, ukuvumela ukudonsa ngempumelelo futhi kudlulise amandla okushisa ngesikhathi senqubo yokushisa.

 

ezintathu. Ukuhlaziywa okujulile komgomo wokusebenza

Umgomo osebenzayo weI-Silicon Carbide Graphible ecashile Akanciki kuphela ezicini ezibonakalayo zezinto ezibonakalayo, kepha futhi zincike kakhulu ekusetshenzisweni okusebenzayo kwamandla okushisa ngokusabela kwamakhemikhali. Inqubo ethile imi kanjena:

 

Ukufudumeza okubaleka: Umthombo wokushisa wangaphandle ushisa okubaleka, futhi izinto ze-graphito kanye ne-karicon Carbide ngaphakathi ngaphakathi zidonsa ngokushesha ukushisa futhi zifinyelele amazinga okushisa aphezulu.

 

Ukuphendula kwamakhemikhali e-Endothermic: emazingeni okushisa aphezulu, ukusabela kwamakhemikhali (ukusabela kabusha kwe-redox, ukusabela kwe-pyrolysis, ukusabela kwesiteleka, njll.) Kwenzeka ngaphakathi kokushisa, kukhishwa inani elikhulu lamandla okushisa, adonswa impahla ebekiwe.

 

Ukuqhutshwa okushisayo: Ngenxa yokuvuselelwa okuhle kakhulu kwe-graphite, ukushisa okuthe xaxa kwenziwa ngokushesha kokuqukethwe okuthe xaxa, okwenza izinga lokushisa laso likhuphuke ngokushesha.

 

Ukushisa okuqhubekayo: Njengoba ukusabela kwamakhemikhali kuyaqhubeka nokushisa kwangaphandle kuyaqhubeka, ukucacisa kungagcina izinga lokushisa eliphakeme futhi kunikeze umfudlana oqinile wamandla wokushisa wezinto ezibonakalayo.

 

Lokhu kushisa okusebenzayo kanye nokushisa kwendlela yokusebenzisa amandla okusebenzisa kuqinisekisa ukusebenza okuphezulu kweI-Silicon Carbide Graphible ecashile ngaphansi kwezimo zokushisa eziphakeme. Le nqubo ayigcini nje ngokuthuthukisa ukusebenza kahle kokufudumeza, kepha futhi yehlisa ukulahleka kwamandla, okwenza kube yinto ekhethekile ekukhiqizeni kwezimboni.

 

Ezine. Izicelo ezintsha nezinkomba zokusebenzisa kahle

Ukusebenza okuphakeme kweI-Silicon Carbide Graphible ecashile Kuzinhlelo zokusebenza ezisebenzayo ikakhulukazi ezisetshenziswa ekusetshenzisweni kwayo okusebenzayo kwamandla afudumele nokuqina ngokwezinto ezibonakalayo. Lokhu okulandelayo kunezinsizakusebenza ezintsha nezinkomba zokusebenzisa imali okuzayo:

 

Ukubhema insimbi ephezuluI-Silicon Carbide Graphible ecashile ingathuthukisa ngempumelelo isivinini esishisayo nekhwalithi. Isibonelo, ekunyiseni i-Iron Iron, yethusi, i-aluminium nezinye izinsimbi, ukuvumelanisa okuphezulu okuthe xaxa nokumelana nokugqwala kwenza amandla okumelana nethonya lensimbi ebunjiwe eliphezulu, ukuqinisekisa ukuqina nokuphepha kwenqubo yokunqwabelana.

 

Umkhumbi wokulwa namakhemikhali aphezulu:I-Silicon Carbide Graphible ecashile Ingasetshenziswa njengesitsha esihle sokuphendula okushisa okuphezulu kwamakhemikhali. Ngokwesibonelo, embonini yamakhemikhali, ukusabela okuthile okuphezulu okuphezulu kudinga imikhumbi eqinile futhi engamelana nokugqwala, kanye nezimpawu zeI-Silicon Carbide Graphible ecashileukuhlangabezana nalezi zidingo.

 

Ukuthuthukiswa kwezinto ezintsha: ocwaningweni nasekuthuthukisweni kwezinto ezintsha,I-Silicon Carbide Graphible ecashile Ingasetshenziswa njengemishini eyisisekelo yokucubungula okushisa okuphezulu kanye nokuhlanganiswa. Ukusebenza kwayo okuzinzile nokusebenza okusebenzayo okushisayo kunikeza indawo enhle yokuhlola futhi kukhuthaze ukuthuthukiswa kwezinto ezintsha.

 

Ubuchwepheshe bokonga amandla nobuchwepheshe bokuphuma kwamandla: Ngokuphumelela izimo zokuphendula zamakhemikhali zeI-Silicon Carbide Graphible ecashile, ukusebenza kwayo okushisayo kungathuthukiswa futhi ukusetshenziswa kwamandla kuncishisiwe. Isibonelo, ukwethulwa kwama-catalysts ku-Elensible kufundwa ukuthuthukisa ukusebenza kahle kokuphendula kabusha, ngaleyo ndlela kunciphise isikhathi sokushisa kanye nokusetshenziswa kwamandla.

 

Ukuhlanganiswa okubonakalayo kanye nokuguqulwa: ukuhlanganisa nezinye izinto zokusebenza okuphezulu, njengokungeza imicu ye-ceramic noma ama-nanomatadium, kungathuthukisa ukumelana nokushisa namandla okushisaI-Silicon Carbide Graphible ecashiles. Ngaphezu kwalokho, ngokusebenzisa izinqubo zokuguqulwa njengokuphathwa kobuso obukhona, ukumelana nokugqwala kanye nokusebenza kahle kwe-thermal okusebenzayo kungathuthukiswa kakhulu.

 

5. Isiphetho kanye namathemba esikhathi esizayo

Isimiso se-Endothermic seI-Silicon Carbide Graphible ecashile Ukusetshenziswa okusebenzayo kwamandla okushisa asuselwa kwizakhiwo zawo ezibonakalayo kanye nokusabela kwamakhemikhali. Ukuqonda nokwandisa lezi zimiso kubaluleke kakhulu ekuthuthukiseni ukusebenza kahle kokukhiqizwa kwezimboni kanye nocwaningo lwezinto zokwakha. Ngokuzayo, ngentuthuko eqhubekayo yezobuchwepheshe kanye nokuthuthuka okuqhubekayo kwezinto ezintsha,I-Silicon Carbide Graphible ecashilekulindeleke ukuthi badlale indima ebalulekile emasimini angaphansi aphezulu.

 

Ngokuqamba okuqhubekayo nokwenza kahle,I-Silicon Carbide Graphible ecashile Sizoqhubeka nokwenza ngcono ukusebenza kwayo futhi ushayele ukuthuthukiswa kwezimboni ezihlobene. Ekumotweni kwamazinga okushisa okushisa, ukusabela kwamazinga okushisa okuphezulu, kanye nokuthuthukiswa okusha kwezinto ezibonakalayo,I-Silicon Carbide Graphible ecashile uzoba yithuluzi elisemqoka, asiza imboni yanamuhla nocwaningo lwesayensi ukufinyelela ukuphakama okusha.
