Sei Stainless simbi ichiita ngura?

1, Chii chinonzi Stainless simbi?

Stainless simbi imhando yesimbi.Simbi inoreva simbi ine isingasviki 2% kabhoni (c), uye inopfuura 2% iron.Alloy zvinhu zvakaita sechromium (CR), nickel (Ni), manganese (MN), silicon (SI), titanium (TI) uye molybdenum (MO) inowedzerwa kusimbi mukunyungudutsa kuvandudza kushanda kwesimbi uye. ita kuti simbi ive necorrosion resistance (kureva kuti haina ngura), inova ndiyo yatinoti simbi isina tsvina.Semuenzaniso, yedu Stainless simbi zvigadzirwa:banjos, swivel house end joint,imba clamps,exhaust akawanda, nezvimwewo.

2、 Sei simbi isina tsvina ichiita ngura?

Simbi isina tsvina ine simba rekudzivisa kusvibiswa kwemhepo - rust resistance, uye inokwanisawo kurwisana nekuora mukati mepakati ine asidhi, alkali uye munyu, kureva, kurwisa kwemarara.Nekudaro, iyo corrosion resistance yesimbi inosiyana nemakemikari ayo, mutual state, sevhisi mamiriro uye nharaunda yepakati mhando.

Simbi isina tsvina iganda rakatetepa kwazvo, rakasimba uye rakatsetseka rakagadzikana chromium rich oxide film (inodzivirira firimu) inoumbwa pamusoro payo kudzivirira maatomu eokisijeni kuti asarambe achipinda nekuita oxidize, uye kuwana kushomeka kwekuora.Kana firimu rikangoramba richiparara nokuda kwechimwe chikonzero, maatomu eokisijeni ari mumhepo kana mvura acharamba achipinda kana kuti maatomu esimbi ari musimbi anoramba achiparadzana, ogadzira iron oxide yakasununguka, uye nzvimbo yesimbi inoramba ichiita ngura.Kune akawanda marudzi ekukuvadza kune iyi kumeso kumeso mask, uye zvinotevera zvakajairika muhupenyu hwezuva nezuva:

.Mumhepo ine mwando, iyo condensate pakati pezvakabatanidzwa nesimbi isina tsvina inozvibatanidza mudiki cell, zvichiita kuti electrochemical reaction uye kukuvadza firimu rinodzivirira, iro rinonzi electrochemical corrosion.

2. Organic juices (yakadai semavise nemiriwo, muto wenoodle uye phlegm) inonamatira pamusoro pesimbi isina tsvina.Pamberi pemvura uye okisijeni, vanoumba organic acids, iyo inoparadza simbi yesimbi kwenguva yakareba.

3. Pamusoro pesimbi isina tsvina inonamatira neasidhi, alkali uye munyu zvinhu (zvakadai semvura yealkali uye lime mvura yekupfapfaidza bvunzo yekushongedza madziro) kukonzera ngura yenzvimbo.4. Mumhepo yakasvibiswa (mhepo ine sulfide yakawanda, oxide uye hydrogen oxide), paunosangana nemvura yakanyungudutswa, sulfuric acid, nitric acid uye acetic acid liquid points ichaumbwa, zvichiita kuti kemikari iparadze.

3, Maitiro ekugadzirisa ngura mavara pasimbi isina tsvina?

a) Chemical nzira:

Shandisa pickling paste kana kupfapfaidza kubatsira zvikamu zvine ngura kuti zvipfuure uye ugadzire chromium oxide firimu kudzoreredza kuramba kwecorrosion.Mushure mekunhonga, zvakakosha zvikuru kugeza nemvura yakachena zvakanaka kuti ubvise zvose zvinosvibisa uye masara e acid.Mushure mekurapa kwese, shandisa midziyo yekupolisha kukwenenzvera zvakare uye kunama newakisi yekupolisha.Kune avo vane makwapa mashoma munharaunda, musanganiswa we1: 1 wepeturu neoiri yeinjini unogona kushandiswa kupukuta makwapa nerag rakachena.

b) Mechanical nzira:

Kucheneswa kwekuputika, kuputika kwepfuti negirazi kana zvimedu zveceramic, kutsakatisa, kukwesha nekupukuta.Zvinokwanisika kupukuta kusvibiswa kunokonzerwa nezvinhu zvakabviswa kare, zvinhu zvekupukuta kana zvinhu zvekuparadza kuburikidza nemichina nzira.Mhando dzese dzekusvibiswa, kunyanya simbi dzekunze, dzinogona kuita ngura, kunyanya munzvimbo ine mwando.Naizvozvo, nzvimbo yakacheneswa nemichina inofanirwa kucheneswa zviri pamutemo pasi pemamiriro akaoma.Iyo mechanical nzira inogona chete kuchenesa nzvimbo, uye haigoni kushandura kupikisa kwehutu hwezvinhu pachayo.Naizvozvo, zvinokurudzirwa kukwenenzvera zvakare nemidziyo yekupolisha mushure mekuchenesa michina uye nekusimbisa newakisi yekupolisha.
