Ifomu eyonakalisiweyo ye-LSAW umphezulu wombhobho wentsimbi

LSAW umbhobho wentsimbiyenziwa ngumaleko ongaphezulu obhityileyo kakhulu kunye nozinzo oluqinileyo lwefilimu ye-oxide ecocekileyo ene-chromium (ifilimu ekhuselayo), ukuthintela ukungena ngokuqhubekayo kwee-athomu ze-oksijini, kwi-oxidation, kunye nokufikelela kwikhono lokuchasana nokubola.Ukuba kukho isizathu esithile, le filimu yaba ukutshatyalaliswa rhoqo, umoya okanye ioksijini engamanzi okanye iiathom zentsimbi ziya kuqhubeka ukungena athom yentsimbi ngaphandle uhlalutyo rhoqo ukubunjwa oxide yentsimbi ekhululekileyo, umhlwa phezu metal iya kuba rhoqo .Le filimu yomphezulu ngendlela yomonakalo omkhulu, eqhelekileyo kubomi bemihla ngemihla ishwankathelwa ngolu hlobo lulandelayo:

1 LSAW umbhobho wentsimbi umphezulu idiphozithi imveliso kunye nezinye izinyithi eziqulathe amasuntswana othuli okanye heterogeneous metal fixtures kumoya ofumileyo, kunye nentsimbi stainless fixtures phakathi condensate, zombini kunye zibe micro-ibhetri, ebangela reactions yemichiza yombane, ifilimu ekhuselayo yonakele, yibize loo nto i-electrochemical corrosion.

2 Umbhobho othe ngqo wancamathela kumphezulu wejusi ye-organic (efana nemifuno, isuphu, isikhohlela, njl.njl.), ioksijini kwindawo yamanzi, yenza iiasidi eziphilayo, iiasidi eziphilayo ubude kukuhlwa komphezulu wesinyithi.

3 LSAW umbhobho wentsimbi umbhobho adhesion umphezulu asidi, ialkali, iityuwa (ezifana ilye yokuhombisa eludongeni, ukuchaphaza kukalika), ebangela umhlwa ekuhlaleni.

I-4 emoyeni ongcolileyo (equlethe inani elikhulu le-sulfide, i-carbon dioxide, i-nitrogen oxide atmosphere), imeko yamanzi adibeneyo ukwenza i-sulfuric acid, i-nitric acid, isisombululo se-acetic acid, ibangela ukubola kweekhemikhali.

Uluhlu lwezicelo lwe-LSAW

​I-LSAW yentsimbi yombhobho ububanzi kuluhlu oluphakathi kwe-406 ~ 1600mm, kwiimeko ezikhethekileyo ngakumbi, umlinganiselo wobunzima bodonga kunye nobubanzi obumalunga ne-0.06 ukuya kwi-0.08.Itekhnoloji yala maxesha yangaphandle inokuvelisa umbhobho ukuya kuthi ga kwi-100mm yobunzima bodonga lombhobho.

Imveliso yezoshishino yentsimbi yentsimbi okanye i-LSAW ipayipi yensimbi kuphela iindlela ezimbalwa, umehluko womgaqo yindlela yokwenza umbhobho wensimbi, umbhobho wensimbi emva kokwenza inkqubo yokulandelela ngokusisiseko iyafana.Imigaqo-nkqubo yokwenza i-weld ixhomekeke kulwabiwo lwentsimbi, ngokuhambelana nokuhanjiswa kwemibhobho ukuwelda iifom ezimbini ezisisiseko: umthungo othe tye kunye nombhobho wentsimbi we-spiral.Ngokuhambelana noku, umthungo othe tye odityanisiweyo wemveliso yombhobho kwimveliso kunye nokuveliswa kombhobho womthungo ojikelezayo.Umthungo othe tye kunye nombhobho wentsimbi yomthungo eyona ndlela isetyenziswa kakhulu yi-arc welding (SAW), umgangatho wayo olungileyo, imveliso ephezulu, itekhnoloji ivuthiwe kwaye izinzile.Okwangoku, umbhobho wentsimbi yomthungo othe tye osetyenziswa ngokubanzi kumazwe aphesheya kolu luhlu lulandelayo: ukuthuthwa komhlaba womoya kunye nolwandle, amanzi kunye nemibhobho ye-oyile;iikhemikhali zokuthutha kunye neemveliso zeekhemikhali zetyhubhu yensimbi engenasici;isakhiwo semizi-mveliso yaselwandle kunye nombhobho;ukwenziwa kwebhoyila kunye nenjongo eyodwa yombhobho wesakhiwo ityhubhu.
