(Ibhola le-Silicon NitrideIkhiqizwe nguWintrustek)

I-silicon nitrideisetshenziswa kaningi njengengxenye ebalulekile yokugaya ama-rotor, imidiya yokugaya, nama-turbines. Imikhiqizo eyenziwe nge-silicon nitride inokuqina okufanayoi-zirconiauma kuqhathaniswa nezinto ezivamile, kodwa futhi banobulukhuni obuphakeme nokugqoka okuncane.

I-Si3N4 ibhola lokugayaUkuzinza kwe-thermal okuqinile kuyenza ifaneleke ukusetshenziswa kumazinga okushisa aphezulu kanye nezinqubo zokugaya ze-cryogenic. Ukumelana nokushisa okukhethekile kwebhola kulivumela ukuthi likwazi ukubekezelela ukushintsha kwezinga lokushisa ngaphandle kokulahlekelwa ukusebenza kwalo noma isimo. Ilula ngo-60% kunensimbi, inweba kancane ngokushisa, futhi inezindleko zokusebenza eziphansi zizonke uma iqhathaniswa nezinye izindlela zokugaya. Ngenxa yokuqina kwayo okukhulu, ingakwazi ukumelana nezidingo zezinqubo eziningi zokucwenga impushana yensimbi nokuchotshozwa kwayo. Uma kudingeka ubulukhuni obuphezulu, ukungcoliswa okuncane, kanye nokuhuzuka okuncane, lokhu kuyindlela ekahle yokugaya.

Izakhiwo

• Amandla aphezulu

• Ukumelana okuhle kakhulu nokugqoka nokugqwala

• Ukumelana namazinga okushisa aphezulu

• Ukufakwa kukagesi

• Izakhiwo ezingezona uzibuthe

Izinzuzo eziyinhloko ze-silicon nitride ngaphezu kwamabhola ensimbi:

1. Ngenxa yesisindo sayo esingaphansi ngo-59% kunebhola lensimbi, kunciphisa ngokuphawulekayo ukugoqa, amandla amaphakathi, nokuguga komgwaqo ngenkathi ibhereyi isebenza ngesivinini esiphezulu;

2. Njengoba i-elasticity modulus inkulu ngo-44% kuneyensimbi, ukuwohloka kuncane kakhulu kunokwebhola lensimbi;

3. I-HRC ingama-78, futhi ubulukhuni bukhulu kunobensimbi;

4. I-coefficient encane yefriction, insulation kagesi, non-magnetic, kanye nokumelana okwengeziwe nokugqwala kwamakhemikhali kunensimbi;

5. The material's coefficient of thermal expansion is 1/4 of that of steel, making it resistant to abrupt temperature changes;

6. I-RA ingafinyelela ku-4-6 nm, ikwenze kube lula ukuthola indawo ecishe ibe nasici;

7. Ukumelana nokushisa okuqinile, ku-1050℃, ibhola le-silicon nitride ceramic ligcina amandla alo amangalisayo nobulukhuni;

8. Ingasebenza ngaphandle kokugcoba uwoyela futhi ingagqwali.
