Stainless simbi screws vs. carbon steel screws: Nzira yekusarudza yakanakisa yekusimbisa mhinduro kwauri?

Muminda yekuvaka, kugadzira michina uye gadziriso yeinjiniya, kusarudzwa kwezvikwiriso kunobata zvakananga kuchengetedza kwechimiro, mari yekugadzirisa uye hupenyu hweprojekiti. Vatengi vazhinji vanowanzowira mudambudziko: simbi isina tsvina screws inodhura, uye kabhoni simbi screws zviri nyore kuita ngura - sei kusarudza? Senyanzvi yekugadzira yekumhanyisa, Nanning Aozhan Indasitiri ichakubatsira iwe kuwana yakanakisa mhinduro kuburikidza nekuita kuenzanisa + zviitiko chaizvo!

Musiyano wakakosha pakati pesimbi isina tsvina uye kabhoni simbi screws

1. Corrosion resistance: kiyi yekusarudza hupenyu hwebasa

Stainless simbi screws (senge 304/316) ine chromium uye nickel, izvo zvinogona kuumba oxide inodzivirira layer inodzivirira hunyoro, munyu pfapfaidzo uye kemikari. Carbon steel screws ichaita ngura mumwedzi 6-12 munzvimbo ine hunyoro, kunyanya munzvimbo dzemahombekombe kana maindasitiri, uko chiyero chekuora chinokurumidza.

Mhosva chaiyo: Imba yekuchengetera zvinhu yakashandisa kabhoni simbi screws kugadzirisa chimiro chesimbi. Pashure pemakore matatu, matenga edenga akasununguka nokuda kwengura, uye mari yokugadzirisa yakapfuura US$50,000; nepo imwe imba yekuchengetera zvinhu yakachinjira kune 304 Stainless simbi screws yakanga isina matambudziko ekuora kwemakore gumi.

2. Kuenzanisa kwesimba: hazvisi zvese zviitiko zvinoda simba repamusoro

Carbon steel screws inowanzova nepamusoro-soro simba (se8.8, 10.9), yakakodzera kune zvinorema-basa zvimiro. Nekudaro, kusimba kwesimbi isina simbi screws (yakadai seA2-70, A4-80) inogona kusangana nezvakawanda zvekuvaka uye zvemagetsi zvinodiwa. Kunze kwekunge iri yakanyanyisa-inotakura mamiriro (senge mabhiriji, inorema muchina), hapana chikonzero chekunyanya kutsvaga simba repamusoro.

3. Kuongororwa kwemutengo: kuchengetedza mari kwenguva pfupi vs. kukosha kwenguva refu

Mari yekutanga yekutenga kabhoni simbi screws ndeye 30% -50% yakaderera pane yesimbi isina tsvina, asi nguva dzose anti-rust kurapwa kana kutsiva kunodiwa. Munzvimbo dzine hunyoro, acidic uye alkaline, iyo yakazara yehupenyu kutenderera mutengo westainless simbi screws yakadzikira - kubvisa kazhinji kugadzirisa uye kurasikirwa kwenguva.

Sarudzo Yekutungamira: Sarudza zvinoenderana nemamiriro ako ekushandisa

Mamiriro ekusarudza kabhoni simbi screws

1. Zvimiro zvenguva pfupi (zvivakwa zvekuratidzira, zvivharo zvenguva pfupi)
2. Zvakanyatsooma zvemukati nharaunda (kushongedza kwehofisi, musangano wefenicha)
3. Mapurojekiti anodhura zvakanyanya uye anogona kugamuchira kutsiva nguva dzose

Scenario yekusarudza Stainless simbi screws

1. Nzvimbo dzekunze dzekunze (matenga, magadhi, zvifambiso)
2. Hunyoro hwepamusoro / nzvimbo dzine munyu wepamusoro (zvivakwa zvemahombekombe, ngarava, zvidyarwa zvemakemikari)
3. Chikafu nemidziyo yekurapa (inofanirwa kusangana nehutsanana zviyero)
4. Zvakaoma-kuchengetedza nzvimbo (yakakwirira-yakakwirira zvimiro, pasi pevhu mapaipi)

Yakagadzirirwa mhinduro dzeNanning Aozhan

Isu tinonzwisisa zvinodikanwa zvakasiyana zvepurojekiti yega yega, saka tinopa:

1. Material yekuyedza sevhisi: inokubatsira kuti uone kana ma screws aripo akakodzera nharaunda iripo
2. Musanganiswa wekushandisa mhinduro: shandisa simbi isina tsvina kune akakosha zvikamu uye kabhoni simbi kune isiri-kiyi zvikamu kuti uwedzere mari
3. Kukwidziridzwa kwekurapa kwepamusoro: Dacromet/hot-dip galvanizing yekabhoni simbi screws kuwedzera hupenyu

Sei kusarudza isu?

10+ makore ekutarisa pakugadzira fastener, zvinoenderana ne ISO/GB/DIN zviyero

Tsigira diki batch yekuyedza maodha, simbisa mhedzisiro isati yatenga yakakura
