Aisi d2 1.2379 Chida Chachitsulo
Kufotokozera kwaifupi:
D2 ndi kaboni kwambiri, chitsulo chachikulu-chromiom chilengedwe chodziwika bwino chovuta kwambiri komanso kulimba mtima. Amagwiritsidwa ntchito nthawi zambiri pamapulogalamuwo akamwalira, kupanga kufa, komanso kudula zida.
1.2379 Chida Chachitsulo:
D2 zitsulo, zopezeka mumitundu yozungulira ya bar ndi mbale, ndizabwino pakupanga zingwe zozizira ndi zigawo zowopsa, mawonekedwe owoneka bwino, komanso zofunikira pakukana ndi kuvala kukana. Amadziwikanso kuti ndi masamba a din 1.2379 ndi Jis skid11, imagwera m'gulu la ma carbon-carbon ozizira ozizira. Izi zachitsulo zimakonda kugwiritsa ntchito mofala chifukwa cha kuuma kwake kopitilira muyeso komanso kukana kwa maxidation-kutentha kwambiri.

Chifukwa chiyani tisankhe?
•Mutha kupeza zinthu zabwino malinga ndi zomwe mukufuna pamtengo wochepera.
•Timaperekanso obwezeretsanso, fob, CFR, COB, ndi khomo ndi mitengo ya khomo. Tikukulimbikitsani kuti muchite zotumizira zomwe zingakhale zachuma.
•Zipangizo zomwe timapereka ndizotsimikizika kwathunthu, kuchokera ku satifiketi ya sifiketi yomaliza yomaliza. (Malipoti adzawonetsa zofunikira)
•Tikutsimikizira kuyankha mkati mwa 24hours (nthawi zambiri nthawi yomweyo)
•Perekani lipoti la SGS.
•Timadzipereka kwambiri kwa makasitomala athu. Ngati sizingatheke kukwaniritsa zofunikira zanu mutapenda zosankha zonse, sitikusocheretsani popanga malonjezo abodza omwe angapangitse ubale wabwino womwe ungapangitse ubale wabwino.
•Perekani ntchito imodzi.
Kulongedza:
1. Kulongedza ndi kofunikira kwambiri makamaka pamayendedwe apadziko lonse lapansi omwe amapereka njira zosiyanasiyana kuti afike komwe akupita, motero timayika nkhawa zapadera pofotokoza.
2. Timanyamula zogulitsa zathu m'njira zingapo, monga,
