Ndudu zikusintha kukhala zopakira zapulasitiki zomwe zimatha kuwonongeka ku India.
Kuletsa kwa India mapulasitiki 19 ogwiritsidwa ntchito kamodzi kwapangitsa kuti makampani ake afodya asinthe. Pasanafike pa Julayi 1, opanga ndudu ku India anali atasintha mapaketi awo a pulasitiki wamba kuti azitha kuwonongeka. Bungwe la Tobacco Institute of India (TII) likunena kuti mamembala awo atembenuzidwa ndipo mapulasitiki osawonongeka omwe amagwiritsidwa ntchito amakwaniritsa miyezo yapadziko lonse lapansi, komanso muyezo wa BIS womwe wangotulutsidwa kumene. Amanenanso kuti kuwonongeka kwa mapulasitiki omwe amatha kuwonongeka kumayamba kukhudzana ndi nthaka ndipo mwachilengedwe amawonongeka mu kompositi popanda kukakamiza kusonkhanitsa zinyalala zolimba ndikuzibwezeretsanso. -
Kuwunika Kwachidule Kwa Kagwiritsidwe Ntchito Kwa Msika Wapakhomo Wa Calcium Carbide Mu Hafu Yoyamba Ya Chaka.
Mu theka loyamba la 2022, msika wapakhomo wa calcium carbide sunapitirize kusinthasintha kwakukulu mu 2021. Msika wonse unali pafupi ndi mtengo wamtengo wapatali, ndipo unkasintha ndi kusintha chifukwa cha kukhudzidwa kwa zipangizo, kupezeka ndi kufunikira. , ndi mikhalidwe yakunsi kwa mtsinje. Mu theka loyamba la chaka, panalibe kukula kwatsopano kwa zomera zapakhomo za calcium carbide PVC, ndipo kuwonjezeka kwa msika wa calcium carbide kunali kochepa. Ndizovuta kwa mabizinesi a chlor-alkali omwe amagula calcium carbide kuti asunge katundu wokhazikika kwa nthawi yayitali. -
Kuphulika kunachitika mu PVC reactor ya chimphona cha petrochemical ku Middle East!
Chimphona cha petrochemical ku Turkey Petkim adalengeza kuti madzulo a June 19, 2022, kuphulika kunachitika pa chomera cha Aliaga. ngoziyi inachitika mu riyakitala ya PVC ya fakitale, palibe amene anavulala, moto unayamba kuyendetsedwa mofulumira, koma gulu la PVC likhoza kukhala lopanda intaneti kwakanthawi chifukwa cha ngoziyo.
