Shaashado caag ah oo iib ah --ka-hortagga xannibaadda daloollada labajibbaaran ee ka-hortagga dhuxusha Hindiya. 305×610mm heerka & cabbirada gaarka ah. Qiimaha warshadda, MOQ dabacsan HS 847490 waa diyaar.
Waxaan ahay Agaasimaha Ganacsiga Dibadda ee Rio Minerals. Muddo 21 sano ah, waxaan bartay in suuqa baaritaanka Hindiya uu ku shaqeeyo xeerar ka duwan kan adduunka intiisa kale. Arrimaha qiimaha - qoto dheer. Laakin sidoo kale isku halaynta waa marka geedkaagu socdo 330 maalmood sanadkii. Waa kan sida aan labadaba isu dheellitirno.
Dhuxusha Hindiya ma joogsato - sidoo kale maaha in shaashadahaagu
Hindiya waxay ka shaqeysaa in ka badan 1 bilyan oo tan oo dhuxul ah sannadkii - waa dalka labaad ee ugu wax soo saarka badan dhuxusha. Laakin waa kuwan waxa tirooyinka wax soo saarka aysan kuu sheegin: Dhuxusha kulaylka Hindiya waxay caadi ahaan sidataa 30-45% maadada dambaska oo leh 8-18% qoyaan oogada. Isku-dhafkan - dambas sarreeya, qoyaan badan, qaybo yaryar - waxay si gaar ah u neceb yihiin qalabka baaritaanka.
Ku dhex soco goob kasta oo dhuxusha lagu dhaqo oo ku taal Jharkhand, Chhattisgarh, ama Odisha, waxaadna arki doontaa isla goobta: shaqaalaha dayactirka oo hoos u dhigaya muraayadaha indhaha ee indhoolayaasha ah oo leh diyaarado biyo cadaadis sare leh, beddela shaqada ka dib. Ganaaxyada ka yimaada dhuxusha-sare ee Hindiya kaliya maaha muraayad indho-la'aan ah - waxay sameeyaan koollo dhoobo u eg oo ku adkaata lakabka sibidhka oo kale saacado gudahood. Guddidu waxay isbedeshaa 28-45 maalmoodba mar waxaa loola dhaqmaa si caadi ah. Ma aha inay noqdaan.
Barnaamijkeena shaashada caagga ah ee iibka ah waxa uu ka hadlayaa madaxa-on falsafad injineernimo oo gaar ah: naqshadaynta dhuxusha Hindiya, ee maaha buug-gacmeed caalami ah. Guddi kasta oo aan u dhoofno Hindiya waa la isku daray oo waa la daaweeyay iyada oo loo maleynayo in ay ka shaqeyn doonto 35%+ ash Gondwana dhuxusha biyaha buufiska ah, wareegyada shaqada 24-saac, iyo heerkulka jawiga oo ku dhacay 48 ° C galabnimadii May ee Korba.
Natiijadu? Shaashadayada caag-ka-hortagga ah ee kala-soocidda dhuxusha waxay bixisaa 14-18 toddobaad oo adeeg ah xaaladaha ay xirmooyinka PU-da caadiga ahi ku fashilmaan toddobaadyada 5-7. Ma aha sababtoo ah waxaan isticmaalnaa walxo sixir ah - laakiin sababtoo ah waxaan ku qeexnay Shore 60A caag dabiici ah oo leh meelo godad leh oo si gaar ah loogu talagalay inay iska caabiyaan dhaqanka samaynta koollada ee ganaaxyada dhuxusha-sare ee Hindiya.
