Ukomelela okukhethekileyo nge-silicon carbide tube

I-Silicon carbide (I-sic) Iityhubhu zibonelela ngezicelo ezininzi zemizi-mveliso ukunceda inkampani yakho ifikelela kulonwabo olukhethekileyo. Ngenxa yamandla akhe okhethekileyo kunye nobomi obude, Iityhubhu ze-SIC zisebenza njengamandla anamandla emva kwenkqubela phambili kwaye zibuyile ikamva lethu.

Izinto eziguquguqukayo ezinamandla aguqukayo kwiDayimane ezinokuthelekiswa neDayimane ngaphandle koxinzelelo oluphantsi koxinzelelo phantsi koxinzelelo, Ukuqhayisa ubunzima obuqinileyo.

Amandla aphezulu

I-Silicon Carbide yinto eyomeleleyo neyaselayo enokumelana nobushushu obugqithisileyo kunye neemeko eziya kuthi zonakalise izinto ezincinci, Ngelixa amandla ayo okunxibelelana ayakuvumela ukuba ixhathise ukuxhathisa – Ukwenza ukuba icandelo elifanelekileyo le-ceramic lezicelo ezifuna izinto ezomeleleyo nezihlala ixesha elide.

Ngobunzima obuphezulu obuphezulu (6.8 Mpa m0.5) kunye nomongezo woMncinci (490 I-GPA), Ezi zixhobo zinokumelana nezicelo zoxinzelelo oluphezulu ngokulula, Ngelixa ukuqhubela phambili kwe-thermal kuvumela ukutshintshelwa kobushushu ngokufanelekileyo ngelixa incipha iindleko zenkqubo yenkqubo yakho yenkqubo yakho.

Impendulo ye-Silicon ye-selied ye-selid yenziwa ngeqondo lokuphendula eliphezulu le-thermochemical le fuseli silicon carbide powder kunye ne-grains. Oku kudala amandla aphezulu okutshintsha, Ukunganyangeki, Ukunganyamezelana kweekhemikhali kunye nokunyamezelana kobushushu – igqibelele kwiziko kunye nesibini esisesibini – kunye nokulungiswa okuncitshisiweyo kunye neendleko zokulungisa ezikugcina imali ngokuhamba kwexesha. Ngaphezulu, Ubume babo bokukhanya bakwenza ufakelo ngokukhawuleza kwaye alunabuhlungu.

Ukunganyangeki kwe-Porrosion

Iityhubhu ze-selicon carbic cuwes zizinto ezomeleleyo ezomeleleyo, Iimeko ezibi kakhulu kunye neekhemikhali ezinesiphoso esincinci. I-hards yabo elukhuni yayo kwaye bayayixhathisa i-abrasions kunye nokukhukuliseka ngokukhululekileyo – Iimpawu ezenza ukuba zibe nezinto ezigqibeleleyo zezityalo zamandla.

Izixhobo ze-ceramic zinomthamo wokumelana nobushushu obugqithisileyo kunye noxinzelelo olungagungqiyo ngaphandle kokulalanisa kwamehlo. Ukwanda kwabo okuphantsi komhlaba kunye nokuhamba okuphezulu komhlaba kuyabavumela ukuba baphendule ngokukhawuleza kwaye baqhelane ngokulula kwiqondo lobushushu ngaphandle kokulalanisa okanye ukuqina.

I-selicon ye-selicon ye-selicon carbide iyenza ukhetho lwezinto ezibonakalayo kwiziko kunye nezinye izixhobo zeshishini, Ukunikezela ukunganyangeki kwe-aminion engathandekiyo kunye nokukhuselwa kwiindawo ezinobunzima kunye neekhemikhali ezinobuchule. Ukuchasana ne-acid ifihla i-cubies ye-acid-i-acid eyenziwe kumphezulu wayo – Ukuqhubela phambili ngokuchasene neemeko ze-acidic – Ngelixa ukungazinzanga kwaso kunye nokuchasana nokothusayo kothusayo kuyandisa ukomelela kwayo.

Ukungazithembi kweekhemikhali

I-Silicon Carbide yinto eqinileyo kakhulu enomzimba ophezulu, umatshini, I-Thermal kunye nePhepha lezikhewu. Nge-mohs hardtrance yenqanaba le 13 (iphakamile kunedayimane okanye i-boron carbide), Ingqibelelo yayo yesakhiwo ithintela ishenxisi phantsi koxinzelelo ngelixa lixhathisa ukuvela kweekhemikhali, I-Abrasion, Amaqondo obushushu agqithisileyo kunye nokudlala iqondo lokushisa kunye nokuphila ixesha elide lokusebenza.

Ukuxinana okungafunekiyo kwi-SIC kuhlala kuhlala kungaguquguquki kubushushu obuphezulu kwaye yirhasi, Ukubonelela ngokhuseleko kuhlaselo lwe-acid yi-hydrochloric, I-sulfuric kunye ne-hydrobromic acids kunye neziseko, Iikhemikhali ze-oxiding kunye nezinyibilikisi ezisetyenziselwa imigodi, ukunyibilika kwensimbi, Ukulungiswa kwentsimbi kunye nemveliso yeoyile.

Ngaphambi kokukhetha iBandla laseSilicon leCeramic Ceramic yeBanga lesicelo sakho, Kubalulekile ukuba uvavanye iimeko zokusebenza, Indawo yokuCoca kunye neemfuno zoomatshini. Xa ukhetha ubude be-tube yakho, Ubunzima be-Wall kunye nobubanzi buqinisekile ukuba inokuphatha ooxinzelelo lomzimba kunye neendawo zemichiza kwiseti yakho. Ngaphezulu, Jonga abathengisi abanikezela ngokufuduka ngokwesiko ukuhlangabezana nazo zonke iinkcukacha zakho kunye neemfuno zakho.

Ubomi obude

I-Silicon Carbide ithathe ithathelwe ingqalelo njengento engaqhelekanga ngenxa yamandla ayo ahlukileyo, nxiba ukuxhathisa, Ukungazithembi kweekhemikhali, kunye nepropathi ekhethekileyo yokuqhuba. Kodwa ukuxhaphaza ngokupheleleyo amandla ayo apheleleyo kufuna ubuchwephesha beengcali kunye nokuphatha izinto ezivela kubavelisi bayo.

Itekhnoloji yokuphendula ivumela ukuba le mibhalo ye-ceramic iguqulwe kwi-silica-tow powder ibe ngamaqhekeza anokusetyenziswa kwizicelo ezininzi. Ibonisa i-mohs ubunzima obuqhelekileyo kwiDayimane, kunye nokunganyangeki kakhulu kuhlaselo lwe-acid njenge-nitric kunye ne-hydrofluoric acids – Ukwenza ukuba ukhetho olufanelekileyo lweendawo ezifuna ukumelana nokunganyangeki njengezixhobo zemigodi kunye ne-aerospace i-Enjiniles.

Ngenxa yokwanda kwayo okuphantsi komhlaba, I-firramic fiber i-fiber ilukhetho olufanelekileyo lwezinto ezibonakalayo zokusetyenziswa kunye ne-thermocouples, ukuzikhusela kumonakalo okanye unxibe ngexesha lokusebenza. Ngaphezulu, I-corosion yayo- kwaye ukungavisisani kwe-oxidation kuye kwenza ilungele i-tunnel kilns okanye i-shuttle kilns.
