Ucingo lweKovaryintambo ye-alloy ekhethekileyo ekhula kancinci, eyaziwa ngokubanzi ngeempawu zayo ezizodwa zokufanisa ubushushu.

Idlala indima ebalulekileyo kumashishini asebenza ngobuchule obuphezulu afana ne-elektroniki, i-aerospace, kunye nezixhobo zonyango. Esi sikhokelo siphendula umbuzo ophambili wokuba yintoni intambo yeKovar kwaye sichaza ukusetyenziswa kwayo okuphambili, kunye nezisombululo zethu zentambo yeKovar ezikumgangatho ophezulu.

1. Yintoni i-Kovar Wire?

1.1 Inkcazo ePhambili

Ucingo lweKovar lucingo lwe-iron-nickel-cobalt olunyibilikisiweyo nge-vacuum, oluyilelwe ukulawula ubushushu ngokuthe ngqo.

Eyona nzuzo yayo inkulu kukuhambelana nomlinganiselo wokwandiswa kobushushu weglasi ye-borosilicate kunye neeseramikhi, okuvumela ukutywinwa okungenamthungo.

1.2 Ulwakhiwo oluqhelekileyo lweeKhemikhali

Ucingo lweKovar lunolwakhiwo olulawulwa ngokungqongqo ukuqinisekisa ukusebenza okuzinzileyo:

- Intsimbi (Fe): 53-54% (ibhalansi)

- I-Nickel (Ni): 28.5-29.5%

- I-Cobalt (eCo): 16.8-17.8%

Izinto ezilandelelanayo (Mn, Si, C) zinqunyelwe ngokukodwa ukuba zingadluli kwi-0.5% max nganye.

1.3 Imigangatho ephambili kunye neeMigqaliselo

Ihambelana nemigangatho yamazwe ngamazwe ukuqinisekisa ukuhambelana kuzo zonke izicelo.

- I-ASTM F15 (umgangatho oyintloko weemveliso ze-alloy zeKovar)

- UNS K94610, Werkstoff Nr. 1.3981 (ubizo lwemathiriyeli yehlabathi)

Ikwaziwa ngokuba yi-4J29 ngokwemigangatho yaseTshayina, inokutshintshwa ne-Nilo-K kwezinye iindawo.

2. Iimpawu eziphambili zeKovar Wire

2.1 Ukwanda kobushushu obuphantsi nobuzinzileyo

I-coefficient yayo yokwandisa ubushushu (4.6-5.2×10⁻⁶/℃, 20-400℃) ihambelana ngokugqibeleleyo neglasi ye-borosilicate.

Oku kususa iintanda zoxinzelelo ngexesha lokufudumeza nokupholisa, kuqinisekisa ukutywinwa okuthembekileyo.

2.2 Ukuqhubekeka Kakuhle Kokusebenza

Iyakwazi ukuguguleka kakuhle kwaye ingatsalwa kwiingcingo ezincinci, igotywe, kwaye idityaniswe lula.

Ifanelekile ekutsaleni okubandayo, ekunyatheliseni, nakwiindlela ezahlukeneyo zokuwelda (i-argon arc, i-laser welding).

2.3 Ubushushu obuphezulu kunye nokuzinza kwe-hermetic

Igcina ukusebenza okuzinzileyo kumaqondo obushushu afikelela kwi-450℃, kunye neqondo lokunyibilika eliyi-1450℃.

Yenza izitywino ezingangeni moya ezineglasi/iseramikhi, ezibaluleke kakhulu kwi-vacuum kunye nokusetyenziswa okuthembekileyo.

3. Iingcingo zeKovar kunye neeNtambo zeAlloy ezifanayo: Itheyibhile yokuthelekisa

Le theyibhile ingezantsi igxininisa iingenelo ezikhethekileyo zeKovar wire kunee-constantan kunye nee-cupro nickel wires:

4. Isetyenziswa Njani Intambo yeKovar? Imizekelo yokusetyenziswa kwezixhobo eziphambili

4.1 Ukupakishwa kwe-elektroniki kunye ne-semiconductor

Isetyenziswa njengeentambo ze-lead kwiityhubhu ze-vacuum, ii-transistors, ii-diodes, kunye neesekethe ezidibeneyo.

Ivumela ukutywinwa okungenamoya ngee-insulators zeglasi, ikhusela izinto zangaphakathi kumswakama kunye nongcoliseko.

4.2 Inqwelo-moya kunye neenqwelo-moya

Isetyenziswa kwiinxalenye ze-elektroniki zeenqwelo-moya kunye nezixhobo zonxibelelwano lwesathelayithi.

Uzinzo lwayo lobushushu lumelana nokuguquguquka okukhulu kobushushu kwiindawo zeenqwelo-moya.

4.3 Izixhobo zonyango

Isetyenziswa kwiisensa zonyango, izixhobo zokuxilonga, kunye nezihlanganisi ezifakwe kwi-hermetic.

Ihlangabezana neemfuno ezingqongqo zokuhambelana kwezinto eziphilayo kunye nokuthembeka kwezicelo zonyango.

4.4 Izixhobo zokukhanya kunye ne-Vacuum

Isetyenziswa kwiiseal zeglasi ukuya kwisinyithi kwiifayibha ze-optical, iityhubhu ze-microwave, kunye nezixhobo ze-X-ray.

Iqinisekisa ukuba umoya awungeni kakuhle kwaye ihambelana nobushushu kwiinkqubo ze-optical ezichanekileyo.

5. Iimveliso zethu zeKovar Wire: Izisombululo ezithembekileyo kwiimfuno zakho

5.1 Iinkcukacha ezipheleleyo

Igubungela umgangatho oqhelekileyo (4J29/Kovar) ngobubanzi bentambo ukusuka kwi-0.10mm ukuya kwi-5.0mm.

Ifumaneka ngee-spools, ii-coils, okanye ubude bokusika, ihambelana nemigangatho ye-ASTM F15.

5.2 Iinkonzo ezenzelwe wena

Nika ububanzi beengcingo ezenzelwe wena kunye nonyango lomphezulu (ukugquma, ukunyibilikisa) kwiimfuno ezithile zokutywina.

Yenza izisombululo zokulungiselela ukusetyenziswa okuchanekileyo kwebhetshi encinci okanye iiodolo ezinkulu zemizi-mveliso.

5.3 Ulawulo oluQondileyo loMgangatho

Uvavanyo lwangaphambi kokunikezelwa oluyi-100%, oluquka umlinganiselo wokwandiswa kobushushu, ukwakheka, kunye nokuhlolwa kokunyamezelana kobubanzi.

Imveliso enyibilikiswe nge-vacuum iqinisekisa ukusebenza okufanayo kunye nobunyulu obuphezulu.

6. Isiphelo

Ucingo lweKovar lucingo olungenakutshintshwa olunokwandiswa kancinci, oluchazwa kukufaniswa kwalo kobushushu kunye nokukwazi kwalo ukutywina ngaphandle kobushushu.

Ukusetyenziswa kwayo ngokubanzi kwii-elektroniki, kwi-aerospace, nakwiindawo zonyango kubonisa ixabiso layo elisebenzisekayo kunye nokuthembeka kwayo.

Ucingo lwethu lweKovar olukumgangatho ophezuluIimveliso zisebenzisa ngokupheleleyo ezi nzuzo. Ukuba ufuna i-sealing ethembekileyo okanye i-alloy wire engandi kakhulu, nxibelelana nathi ukuze ufumane iingcebiso ezenzelwe wena kunye nenkxaso yobugcisa.
