M'zaka zaposachedwa, zitsulo zanyengo zakhala zikugwiritsidwa ntchito mochulukira ngati zida zogwirira ntchito zolima kunyumba komanso kukonza malo azamalonda. Chifukwa ndi chitsulo chozizira, chimakhala ndi patina yotetezera yomwe imagonjetsedwa ndi dzimbiri, ndikuipatsa ntchito zosiyanasiyana komanso khalidwe labwino lokongola.

Mwachibadwa, pakhala pali chidwi chambiri pazitsulo zowonongeka ndi zitsulo zanyengo. Ngakhale zodetsazi sizopanda maziko, kutsekereza dzimbiri mumlengalenga -- zomwe tipeza mtsogolomo - mawonekedwe amakina a corT-Ten steel alloys amapangitsa kuti zinthuzo zikhale zoyenera kuti mbewu zikule nyengo zambiri.

M’nkhaniyi tikambirana nkhaniyi. Tidzakambirana za chitsulo cha weathering, ndi dzimbiri ndi dzimbiri. Kenako tikambirana za kulima zitsulo zanyengo ndi njira zabwino zomwe zimagwirizana nazo. Chifukwa chake ngati mukufuna kudziwa ngati chitsulo chanyengo ndi choyenera kwa inu, werengani nkhaniyi!

Kodi weathering steel ndi chiyani?

Weathering steel ndi chitsulo cha chromium-copper alloy weathering, chomwe chimadalira kunyowetsa ndi kuyanika kuti apange dzimbiri zoteteza. M'kupita kwa nthawi, amasintha mtundu, kuyambira ndi mtundu wofiira wa lalanje ndipo amatha ndi patina wa purplish. Ngakhale kuti anthu ambiri ali ndi mayanjano oipa ndi dzimbiri, pamenepa ndi nthawi yofunikira kuti mukhale ndi maonekedwe olondola ndi chisindikizo, ndikupanga wosanjikiza kuti ateteze zina zonse ku dzimbiri. M'malo mwake, chitsulo chanyengo sichimachita dzimbiri ndipo chakhala chikugwiritsidwa ntchito pantchito zomanga zodziwika bwino monga nsanja yowulutsira mawu ku Leeds, UK.

Colton ASTM dzina

CORT-Ten A yoyambirira idalandira dzina la American Institute of Testing and Equipment la aloyi otsika, mphamvu yayikulu, komanso kukana kwa dzimbiri. Gulu latsopano la ASTM la Weathering steel B liri ndi katundu wofanana, koma walandira dzina lodziwika bwino lomwe limasonyeza kuti likhoza kupangidwa ndi kugwiritsidwa ntchito pa mapepala. Zitsulo zomwe zimapanga zitsulo zanyengo ndi mkuwa, chromium, manganese ndi faifi tambala.

Kusiyana pakati pa Corten ndi Redcor

Chigwirizano chimodzi choyenera kufotokozera ndi kusiyana pakati pa zitsulo za nyengo ndi zitsulo zofiira. Chimanga - Khumi ndi chitsulo chosungunuka chomwe chimagwiritsidwa ntchito m'mafakitale a njanji ndi kutumiza. Chitsulo chofiira ndi chitsulo chozizira, koma chimakhala chozizira kwambiri kuposa kutentha. Mpukutu wozizirawu umathandizira kukhazikika kwa mankhwala a pepala lopangidwa ndi pepala, kuti likhale lofanana kwambiri ndi mankhwala.

Kusiyana pakati pa Weathering Steel A ndi Weathering Steel B

Tiyeni tikambiranenso kusiyana pakati pa zitsulo za nyengo A ndi zitsulo zanyengo B. Iwo ali kwenikweni zinthu zofanana, koma weathering zitsulo A, kapena chitsulo choyambirira weathering -TEN, wawonjezera phosphorous kuti zothandiza kwambiri pomanga facades ndi utsi. Weathering STEEL B ndi chitsulo chosasunthika, popanda chigawo chowonjezera ichi, choyenera kwambiri pazinyumba zazikulu. Palinso zosintha zina zobisika pakati pa mankhwala azitsulo ziwiri za corten, koma ndizofunika kudziwa kuti corten A sinagwiritsidwe ntchito popanga cholima cha Bodie Corten.



Chinthu chimodzi chochititsa chidwi pakukula kwa obzalawa ndikuti amatha kulima chakudya mosatetezeka. Iron oxide yomwe imatulutsidwa m'nthaka nthawi ya dzimbiri ilibe poizoni ndipo sichingawononge zomera
