1. Indasitiri kumashure uye kuongorora kudiwa kwemusika
Nekuvandudzwa kwezvinodiwa zvekushanda kwezvikamu mumunda wekugadzirwa kwemidziyo yemaindasitiri, nzira yekurapa pamusoro pesimbi isina tsvina yemaoko, sezvikamu zvakakosha zvekushandisa zvemakina ekufambisa masisitimu, yave musimboti wekubatanidza kuwedzera kukosha kwezvigadzirwa. Zvinoenderana nenhamba, musika wepasi rose weStainless steel handwheel musika uchapfuura US$1.2 bhiriyoni muna 2024, iyo yakakwirira-yakagadziriswa pamusoro pepamusoro inoita 35%.
2. Tsanangudzo yakadzama ye mainstream surface treatment process technology
● Mechanical polishing uye electrolytic polishing
(1.) Maitiro emisimboti:
Mechanical polishing inoshandisa musanganiswa wekukwenenzvera mavhiri uye chromium oxide polishing paste kuti iwane kupera kwepamusoro kuburikidza nekukwesha kwemuviri; electrolytic polishing inoshandisa musimboti we electrochemical dissolution kubvisa microscopic kusaenzana.
(2.) Performance impact:
Mechanical polishing inogona kuwedzera kuomarara kwepasi ne5-10%, uye electrolytic polishing inogona kuwedzera kushora kuramba nekanopfuura ka3.
●Sandblasting uye kudhirowa kwewaya
(1.) Maitiro ekuita:
Sandblasting inoshandisa 120-240 mesh quartz jecha kuti iumbe nzvimbo yakafanana yematte, uye kudhirowa kwewaya kunoburitsa vhudzi rakaita sebvudzi kuburikidza nekukuya kwakananga.
(2.) Chitarisiko chekuita:
The pamusoro roughness Ra of sandblasting anogona kusvika 0.8-1.6μm, uye waya yokudhirowa muitiro anogona kuumba 0.05mm pamwero yakanaka texture.
●Passivation treatment technology
(1.) Chemical process:
A nitric acid-dichromate system inoshandiswa kugadzira 2-5nm gobvu Cr₂O₃ passivation firimu pamusoro.
(2.) Kuvandudza kushanda:
Nguva yekupfapfaidza munyu yakawedzera kubva pamaawa makumi manomwe nemaviri kusvika kumaawa makumi mana nemasere, ichisangana neASTM A967 zviyero.
● Electroplating uye makemikari plating maitiro
Kuenzanisa kwehunyanzvi:
| Process type | Ukobvu hwekunakidzira (μm) | Kuoma (HV) | Bond simba (MPa) |
| Electroplating nickel | 10-50 | 300-400 | 50-70 |
| Chemical nickel plating | 5月25日 | 500-600 | 70-90 |
● Plastic spraying uye nano coating
Innovative process:
Electrostatic spraying ye epoxy resin powder inoumba 60-80μm coating, uye nano titanium dioxide coating inogona kuita basa rekuzvichenesa.
3. Kuenzanisa kwekukanganisa kwemaitiro akasiyana pakuita kwechigadzirwa
| Process type | Corrosion resistance | Pfeka kuramba | Kuoma kwechiso | Bata kuramba |
| Passivation kurapwa | ★★★★★ | ★★☆ | ★★★ | ★★★★ |
| Electrolytic polishing | ★★★★☆ | ★★★ | ★★★☆ | ★★★★★ |
| PVD coating | ★★★★ | ★★★★★ | ★★★★★ | ★★★ |
4. Kuongororwa kwemaitiro ekuratidzwa kwechitarisiko uye mamiriro anoshanda
1. Zvishandiso zvekurapa: girazi polishing (8K giredhi) + plasma kuchenesa, kusangana neGMP utsanana zvinodiwa.
2. Zvishandiso zvemugungwa: zvitatu-zvipfeko zvinoumbwa nenyuchi (kemikari nickel plating + electroplating chromium + nano-kuisa chisimbiso), kusamira kwepfapfaidzo yemunyu > 2000h.
3. Michina yezvokudya: electrolytic polishing + Ral 9006 ruvara rwekupfapfaidza, kusangana neFDA kuonana nemitemo.
5. Indasitiri yekusimudzira maitiro uye tekinoroji innovation gwara
●Maitirwo ezvakatipoteredza: R&D yechromium{{0}yemahara passivation solution inoderedza mari yekuchenesa mvura yetsvina ne40%.
●Marapirwo epamusoro akangwara:
1. Tekinoroji yekutumira mameseji nelaser inowana 0.01mm{2}}level yemapateni chaiwo.
2. Magnetron sputtering coating inovandudza kushanda kwepamusoro.
●Composite process innovation:
Anodic oxidation + micro-arc oxidation composite kurapwa inowedzera kupfeka kuramba index ne8 nguva.
Zvinokurudzirwa kuti makambani ekugadzira atange maitiro ekusarudza matrix modhi zvichienderana nemamiriro ekushandisa, achitarisa pane zvinotevera:
1. Environmental corrosion level (ISO 12944 standard)
.
3. Mutengo wehupenyu hwakazara (kusanganisira mari yekugadzirisa)
Mumakore mashanu anotevera, sezvo zvinodiwa zvemakiyi ezvikamu zvakakosha mu "Made in China 2025" zvichivandudzwa, tekinoroji yekurapa yepamusoro ine zvese zvinoshanda uye kushongedzwa ichave iyo huru yemusika, uye kukura kwepagore kwekukura kwemusika wezvishandiso zvine chekuita nemidziyo inotarisirwa kuramba iri pamusoro pe12%.
