Pakuongorora mapaipi esimbi kuti aone kana paine gasi rine simba shoma, mvura, kana ma network ekudzimisa moto,EN 10255Standard inyaya inowanikwa nevanhu vose panyaya dzinenge dzese dzehunyanzvi. Kune nyanzvi dzekutenga zvinhu, zvakajairika kuenzanisa mitengo zvichibva pamutengo wepatani. Zvisinei, mukuvaka nekuisa zvinhu, mutengo wekutanga wakaderera usingatarisirwi unogona kukonzera mitengo yakavanzika.
Kana mapaipi anounzwa kunzvimbo yepurojekiti akakonzera matambudziko akadai sekusakara kwematurusi nguva isati yakwana panguva yekuisa shinda, kudonhedza majoini, kana ngura yekutanga pamatambo ekubatanidza, mari yekutanga inodzikiswa nekukurumidza nekunonoka kwevashandi uye mari yekugadzirisa patsva. Sechikwata chine ruzivo rwekugadzira chinobata maitiro ese kubva pakugadzirisa simbi isina kugadzirwa kusvika pakuedzwa kwekupedzisira, tinotenda kuti kunzwisisa ruzivo rwakakosha rwekugadzira kunogona kubatsira kuona kuti purojekiti yako inoramba yakachengeteka mukati mebhajeti.
Sei Kugadzirisa Threads Kuchida Kudzora Zvakasimba Zvemukati meCarbon
Zita repamutemo reEN 10255 rinoratidza kuti machubhu aya akagadzirirwa zvakanangana ne"Kubatanidza nekubatanidza shinda."Pasinei netsananguro iyi yakajeka, vatengi vazhinji vanotaura nezvezviitiko zvinoodza mwoyo panguva yekuisa nzvimbo, zvakaita sekuzunguzika kwakanyanya mumichina yekuisa shinda otomatiki, mapurofayi eshinda akapwanyika kana akatsemuka, uye kuchekwa kakawanda kwesimbi dzinodhura dzekucheka.
Chikonzero chikuru chinowanzo dzokera shure pakuomarara kwezvinhu zvakanyanya uye kuumbwa kwemakemikari asina kugadzikana.
Kuti vaderedze mari yekugadzira, vamwe vagadziri vanogona kushandisa genericmakoiri esimbiine hunhu hwemakemikari husingawirirani zvakanyanya. Kune chaiyoMachubhu egiredhi eS195T, kuumbwa kwemakemikari kunofanirwa kutarisirwa zvakanaka kubva pakutanga kusvika pakupera.zvinhu zvakagadziriswadanho:

Protocol Yemhando Yepamusoro: Kuve nechokwadi chekusimbisa Ukobvu Hwakarurama
Mamwe mabhuku ekushambadzira anoratidza kuti kuongororwa kweukobvu hwemadziro kunowanzoitwa mukati-kati mechubhu yakapedzwa panguva yekugadzira nekukurumidza. Kubva pamaonero anoshanda, kuita ongororo ye micrometer yepakati pechubhu pane yega yega yekugadzira nekukurumidza hazvigoneke. Maitiro edu ekusimbisa hunhu anotarisa pane nzira yakajeka, inoshanda, uye yakarurama kwazvo.
Kana saha rinobhururuka richicheka pombi yesimbi inofamba kusvika pakureba, simba resimbi rinoita kuti pave nema "mechanical burrs" madiki uye kushanduka kwemucheto panzvimbo yakachekwa. Kuisa micrometer yakajairika zvakananga pamusoro perim rekunze iri kunogona kukanganisa chiyero, dzimwe nguva kuvhara madziro asina kukora nekuratidza kuverenga kwenhema, kwakakwidibira.
Kuti tidzivise dambudziko iri, timu yedu yemhando yepamusoro yakadzidziswa kutsvedza micrometer kubva pamucheto wekucheka kuti ipfuure zvachose nzvimbo dzakachekwa uye nzvimbo yekuchinjika. Kuiswa uku kunopa kuverenga kwakarurama kwazvo kuve nechokwadi chekuti chinhu chacho chinoremekedza kushivirira kwakanyanya kwemadziro kunobvumidzwa nechiyero -12.5%. Uyezve, kune ese maodha ekubatanidza shinda, tinova nechokwadi chekuti magumo emapaipi anochengetwa akachena zvakakwana uye akatsetseka kuti atsigire kubata kwakachengeteka panzvimbo yacho uye mashandiro akanaka ezvishandiso.
Kunamatira Kunobatanidza: Kudzivirira Kuputika kweZinc Munguva Yekuputira Thread
Munzvimbo dzinodzivirira mvura nemoto, kudzivirira ngura mukati nekunze kwakakosha. Kuisa galvanizing inopisa kunopa dziviriro yakanaka, asi kunoedzwa zvakananga panguva yekuisa: kana mapoka enzvimbo akacheka shinda, mashizha elathe anobvisa chikamu chesimbi iri pajoini. Kana zinc coating isina kunamira zvakanaka, kushushikana kwemuchina kunogona kukonzera kuti galvanizing layer yakapoteredza ibviswe kana kutsemuka sependi yakaoma, zvichiita kuti simbi iri pasi payo ive panjodzi yengura yekutanga.
Kuti tigadzirise dambudziko iri,kunyudza nekupisamaitiro acho anotarisa ma parameter akaiswa neEN 10240tsanangudzo:Mukati meZinc≥55μm(nekusimbisa pamusoro pemukati wakatsetseka usina maronda e zinc akakombama) uyeZinc yekunze≥63μm.Tinotarisa nguva yekushambidza neacid uye tembiricha yepoto yezinc nemazvo. Kuenzana uku kunobvumira zinc yakanyungudutswa nechigadziko chesimbi kubatana zvinobudirira, zvichigadzira jira rakasimba resimbi-zinc alloy. Kana zvishandiso zvekuputira shinda zvikachekwa mupombi, zinc layer inoramba yakabatana zvakasimba nesimbi isingabviswi. Kunyangwe pamudzi wemigero yeshinda ichangobva kuchekwa apo simbi isina chinhu inoonekwa, zinc layer yakapoteredza inopa dziviriro yeanodic, zvichibatsira kuderedza ngura kwenguva refu.
Makamuri ekuongorora salt spray ari kuongorora hot-dip galvanized coating sampuro.
Kuzvipira Kwedu Kwehunhu Uye Kutevedzera Mutemo
