Timapereka malangizo atsatanetsatane okhudza malo ngati gawo la ntchito yathu yolangizana zaukadaulo, ndipo gulu lathu lingakuthandizeni kusankha giredi yoyenera pamalo aliwonse oyika pa projekiti yanu.
Kodi ma chingwe a 304 osapanga dzimbiri amatha nthawi yayitali bwanji poyesa kupopera mchere?
Mu mayeso athu a labotale motsatira muyezo wa ASTM B117,Zingwe 304 zosapanga dzimbiri zachitsulo chosapanga dzimbiriNthawi zambiri amayamba kusonyeza zizindikiro zoyamba za kusintha kwa mtundu wa pamwamba pa madzi pafupifupi maola 500 mpaka 800 akumwa mankhwala ophera mchere mosalekeza. Madontho owoneka bwino a dzimbiri, omwe nthawi zambiri amatchedwa kuyambitsa dzenje, nthawi zambiri amawoneka pakati pa maola 800 ndi 1,200 kutengera kumalizidwa kwa pamwamba ndi chithandizo chilichonse chogwiritsidwa ntchito pambuyo pokonza. Kwa magulu ogula omwe amayesa zomangira za chingwe m'malo ocheperako am'madzi, 304 imapereka mgwirizano woyenera pakati pa mtengo ndi magwiridwe antchito, koma nthawi zonse timalangiza kuwonjezera malire achitetezo pofotokoza zofunikira pa moyo wautumiki. Mizere yathu yopangira imapanga zomangira za chingwe 304 zokhala ndi zomangira zozizira zomwe zimapangitsa kuti zenerali likhale lolimba kwambiri. Timazindikiranso kuti kumalizidwa kwa pamwamba kumakhudza kulimba kwa dzimbiri, ndichifukwa chake timayang'anira mosamala magawo athu a njira yozungulira.
Kodi ndingagwiritse ntchito zingwe zachitsulo chosapanga dzimbiri 201 pafupi ndi nyanja?
We ndikulangiza mwamphamvu kuti musagwiritse ntchito zingwe zachitsulo chosapanga dzimbiri 201Mu malo aliwonse omwe pali mchere wothira, nthunzi ya m'nyanja, kapena madzi amchere mwachindunji. Mu mayeso athu a ASTM B117 a mchere wothira, ma chingwe olumikizirana a 201 grade amayamba kuwonetsa dzimbiri pamwamba pamadzi mkati mwa maola 150 mpaka 300, ndipo dzimbiri limapangika kwambiri pakatha maola 500. Gulu la 201 limagwiritsa ntchito manganese ndi nayitrogeni ngati zinthu zina zomwe zimalowa m'malo mwa nickel, zomwe zimachepetsa kwambiri kukana kwake ku chloride. Ngakhale ma chingwe olumikizirana a 201 ndi oyenera kugwiritsidwa ntchito m'nyumba kapena m'mafakitale ouma komwe kusunga ndalama ndikofunikira, amalephera msanga m'malo am'madzi ndikupanga mavuto akuluakulu achitetezo ndi kukonza. Pa ntchito zapanyanja ndi zomangamanga zombo, tikupangira kuti ma grade osachepera 304, ndipo 316 ndiye mfundo yomwe timakonda. Talemba milandu ingapo pomwe makasitomala adasintha kuchoka pa 201 kupita ku 316 atakumana ndi kulephera msanga mkati mwa chaka choyamba chogwiritsa ntchito.
Kodi mayeso a ASTM B117 a salt spray ndi chiyani ndipo n’chifukwa chiyani amafunikira posankha chingwe chomangira?
Mayeso a ASTM B117 a salt spray ndi mayeso okhazikika ofulumira a dzimbiri omwe amavomerezedwa ndi mabungwe monga ASTM International,NISTndiSAE InternationalMu mayeso awa, zitsanzo zimawonetsedwa ku chifunga chosalekeza cha 5% sodium chloride solution pa madigiri 35 Celsius m'chipinda cholamulidwa. Mayesowa amayesa maola angati omwe chinthucho chingathe kupirira dzimbiri pansi pa mikhalidwe yovutayi. Kwa magulu ogula zinthu za m'madzi, zotsatira za ASTM B117 zimapereka deta yodalirika komanso yofanana poyesa zida zomangira chingwe kuchokera kwa ogulitsa osiyanasiyana. Timagwiritsa ntchito mayesowa ngati gawo la njira yathu yotsimikizira khalidwe la gulu lililonse la zingwe zomangira chingwe zomwe zimagwiritsidwa ntchito m'madzi. Ngakhale palibe mayeso ofulumira omwe amafanana bwino ndi mikhalidwe yeniyeni, ASTM B117 imapatsa makasitomala athu muyezo woyenera woyerekeza magiredi 304, 316, ndi 201 pambali. Timatchulanso njira yogawa kuchokera kuNACE Yapadziko Lonseza deta yeniyeni yokhudzana ndi dziko lenileni.
Kodi kusiyana kwa mtengo pakati pa zingwe zachitsulo chosapanga dzimbiri za 304 ndi 316 ndi kotani?
Kusiyana kwa mitengo pakati pa zingwe zachitsulo chosapanga dzimbiri 304 ndi 316 nthawi zambiri kumayambira pa20% mpaka 40%kutengera kuchuluka kwa oda, kukula kwa chingwe, ndi mitengo yazinthu zopangira zomwe zilipo. Gulu la 316 lili ndi molybdenum, yomwe ndi chinthu chodula kwambiri chopangira zitsulo, ndipo ichi ndiye chinthu chachikulu chomwe chimapangitsa kuti mtengo ukhale wotsika. Pa maoda akuluakulu ogulira zinthu zam'madzi, timagwira ntchito mwachindunji ndi makasitomala athu kuti tikonze bwino zomwe zikufunika ndikupeza yankho lotsika mtengo kwambiri. Nthawi zambiri, timalimbikitsa njira yotsatizana: kugwiritsa ntchito zingwe 316 m'malo omwe ali ndi zinthu zambiri zowononga (malo opasuka ndi omiza) pomwe timafotokoza 304 m'malo omwe ali ndi mlengalenga momwe zinthu sizili zolimba kwambiri. Mphamvu yathu yopangira imatithandiza kupereka zingwe zonse ziwiri moyenera, ndipo timapereka kusanthula kwatsatanetsatane kwa ndalama panthawi yopereka mawu. Tikulimbikitsa magulu ogulira kuti apemphe kusanthula kwathu konse kwa umwini, komwe kumawerengera nthawi zosinthira ndi ndalama zogwirira ntchito pa moyo wonse wa polojekitiyi.
Kodi ndingasankhe bwanji chingwe choyenera kugwiritsa ntchito pa nsanja zakunja?
Kusankha zingwe zomangira mapulatifomu akunja kumafuna njira yolongosoka yomwe imaganizira malo enieni a dzimbiri, zofunikira pamakina, ndi miyezo yoyenera yamakampani. Tikukulimbikitsani kutsatira gulu la ISO 9223 la dzimbiri lamlengalenga kuti mudziwe ngati malo oyikamo ali mu gulu la C4 (lalikulu) kapena C5 (lalikulu kwambiri). Pamapulatifomu akunja, malo otsetsereka ndi madera apafupi ndi nyanja nthawi zambiri amagwera mu C5, zomwe zikutanthauza kuti timatchula zingwe 316 zachitsulo chosapanga dzimbiri ngati maziko. Pamalo okwera omwe ali ndi mchere wochepa, 304 ikhoza kukhala yokwanira. Tikukulimbikitsaninso kuganizira za izi.zingwe zodzitsekera zokhapa ntchito zakunja chifukwa njira yawo yotsekera imapereka kukana kwabwino kwambiri kwa kugwedezeka poyerekeza ndi mitundu yokhazikika ya ma buckle. Gulu lathu laukadaulo limathandiza magulu ogula zinthu ndi ndemanga zapadera ndipo limatha kupereka satifiketi yoyesera pa kutumiza kulikonse. Timaperekanso satifiketi yoyesera pa kutumiza kulikonse.zida zomangira chingweYokonzedwa bwino kuti igwiritsidwe ntchito m'malo otsetsereka, kuonetsetsa kuti imamangiriridwa bwino komanso modalirika ngakhale m'malo ovuta.
Zokhudza Wolemba

Mtsogoleri wa Zaukadaulo
Amadziwika kwambiri posankha zinthu zosapanga dzimbiri, kugwiritsa ntchito zinthu zozizira, komanso njira zothetsera mavuto m'mafakitale. Ndi chidziwitso chambiri pa kuyesa zitsulo komanso kutsimikizira ubwino, wolemba wathu amatsogolera gulu laukadaulo popanga njira zothetsera mavuto okhudzana ndi malo ovuta m'madzi ndi m'mafakitale.
Mukufuna Matayi a Chingwe Osapanga Chitsulo Pa Ntchito Yanu Yapamadzi?
Timapereka zingwe zosapanga dzimbiri zopangidwa ndi chitsulo chosapanga dzimbiri zopangidwa ndi 304, 316, ndi epoxy zokhala ndi satifiketi yoyesera mchere wonse. Lumikizanani ndi gulu lathu laukadaulo kuti mupeze ndemanga yanu ndi tsatanetsatane wa zomwe mukufuna.
