M'mawa wa pa Julayi 26, Chemdo adachita msonkhano wa gulu. Poyamba, manejala wamkulu adafotokoza maganizo ake pa momwe chuma chilili pano: chuma cha padziko lonse chatsika, makampani onse amalonda akunja akuchepa, kufunikira kukuchepa, ndipo chiwongola dzanja cha katundu wapanyanja chikutsika. Ndipo kumbutsani antchito kuti kumapeto kwa Julayi, pali nkhani zina zaumwini zomwe ziyenera kuthetsedwa, zomwe zitha kukonzedwa mwachangu. Ndipo adatsimikiza mutu wa kanema watsopano wa atolankhani sabata ino: Kutsika Kwambiri kwa Malonda akunja. Kenako adapempha ogwira nawo ntchito angapo kuti agawane nkhani zaposachedwa, ndipo pomaliza adapempha madipatimenti azachuma ndi zolemba kuti asunge zikalatazo bwino. -
Ntchito yokulitsa ethylene ndi kuyeretsa ya Hainan Refinery yolemera matani miliyoni iperekedwa.
Pulojekiti ya Hainan Refining and Chemical Ethylene ndi Refining Reconstruction and Expansion Project zili ku Yangpu Economic Development Zone, zomwe zagwiritsidwa ntchito pa ndalama zokwana mayuan opitilira 28 biliyoni. Mpaka pano, kupita patsogolo konse kwa ntchito yomanga kwafika pa 98%. Ntchitoyi ikamalizidwa ndikuyikidwa mu kupanga, ikuyembekezeka kuyendetsa mayuan opitilira 100 biliyoni a mafakitale otsika. Msonkhano wa Olefin Feedstock Diversification ndi High-end Downstream udzachitika ku Sanya pa Julayi 27-28. Pansi pa mkhalidwe watsopanowu, chitukuko cha mapulojekiti akuluakulu monga PDH, ndi kuphwanya kwa ethane, njira yamtsogolo yaukadaulo watsopano monga mafuta osakonzedwa mwachindunji ku ma olefin, komanso kupanga kwatsopano kwa malasha/methanol ku ma olefin kudzakambidwa. -
MIT: Tinthu tating'onoting'ono ta polylactic-glycolic acid copolymer timapanga katemera "wodzilimbitsa".
Asayansi ku Massachusetts Institute of Technology (MIT) akufotokoza mu magazini yaposachedwa ya Science Advances kuti akupanga katemera wodzilimbitsa wokha. Katemera akalowetsedwa m'thupi la munthu, amatha kutulutsidwa kangapo popanda kufunikira jakisoni wowonjezera. Katemera watsopanoyu akuyembekezeka kugwiritsidwa ntchito polimbana ndi matenda kuyambira chikuku mpaka Covid-19. Akuti katemera watsopanoyu wapangidwa ndi tinthu ta poly(lactic-co-glycolic acid) (PLGA). PLGA ndi mankhwala a polymer organic omwe amatha kuwonongeka, omwe si poizoni ndipo ali ndi mgwirizano wabwino ndi thupi. Avomerezedwa kuti agwiritsidwe ntchito mu Implants, sutures, zipangizo zokonzera, ndi zina zotero. -
Kampani ya Yuneng Chemical: Kupanga koyamba kwa polyethylene yopopera!
Posachedwapa, gawo la LLDPE la Polyolefin Center of Yuneng Chemical Company lapanga bwino DFDA-7042S, chinthu chopopera cha polyethylene. Zikumveka kuti chinthu chopopera cha polyethylene ndi chinthu chochokera ku chitukuko chachangu cha ukadaulo wokonza zinthu. Zipangizo zapadera za polyethylene zokhala ndi mphamvu yopopera pamwamba zimathetsa vuto la utoto woipa wa polyethylene ndipo zimakhala zonyezimira kwambiri. Chogulitsachi chingagwiritsidwe ntchito m'minda yokongoletsera ndi yoteteza, yoyenera zinthu za ana, mkati mwa magalimoto, zipangizo zopakira, komanso matanki akuluakulu osungiramo zinthu zamafakitale ndi zaulimi, zoseweretsa, zotchingira misewu, ndi zina zotero, ndipo msika uli ndi chiyembekezo chachikulu. -
Petronas matani 1.65 miliyoni a polyolefin atsala pang'ono kubwerera kumsika waku Asia!
Malinga ndi nkhani zaposachedwa, Pengerang ku Johor Bahru, Malaysia, yayambiranso chipangizo chake cha polyethylene (LLDPE) cha matani 350,000 pachaka pa Julayi 4, koma chipangizochi chingatenge nthawi kuti chigwire ntchito bwino. Kupatula apo, chipangizo chake cha Spheripol cha matani 450,000 pachaka cha polypropylene (PP), matani 400,000 pachaka cha polyethylene (HDPE) ndi chipangizo cha Spherizone cha matani 450,000 pachaka cha polypropylene (PP) chikuyembekezekanso kukwera kuyambira mwezi uno kuti chiyambenso kugwira ntchito. Malinga ndi kuwunika kwa Argus, mtengo wa LLDPE ku Southeast Asia popanda msonkho pa Julayi 1 ndi US$1360-1380/ton CFR, ndipo mtengo wa waya wa PP ku Southeast Asia pa Julayi 1 ndi US$1270-1300/ton CFR popanda msonkho. -
Ndudu zayamba kugwiritsa ntchito mapulasitiki osungunuka omwe amawola ku India.
Kuletsa kwa India kugwiritsa ntchito mapulasitiki 19 ogwiritsidwa ntchito kamodzi kwapangitsa kuti makampani ake a ndudu asinthe. Pasanafike pa Julayi 1, opanga ndudu aku India adasintha ma CD awo akale a pulasitiki kukhala ma CD apulasitiki ovunda. Bungwe la Tobacco Institute of India (TII) likunena kuti mamembala awo asinthidwa ndipo mapulasitiki ovunda omwe amagwiritsidwa ntchito akwaniritsa miyezo yapadziko lonse lapansi, komanso muyezo wa BIS womwe watulutsidwa posachedwapa. Amanenanso kuti kuwonongeka kwa mapulasitiki ovunda kumayamba pokhudzana ndi nthaka ndipo kumawonongeka mwachilengedwe popanga manyowa popanda kukakamiza njira zosonkhanitsira zinyalala zolimba ndi kubwezeretsanso zinthu. -
Kusanthula Kwachidule kwa Kugwira Ntchito kwa Msika wa Calcium Carbide Wapakhomo mu Gawo Loyamba la Chaka.
Mu theka loyamba la chaka cha 2022, msika wa calcium carbide m'dziko muno sunapitirire kusinthasintha kwakukulu mu 2021. Msika wonse unali pafupi ndi malire a mtengo, ndipo unasintha chifukwa cha kukhudzidwa kwa zipangizo zopangira, kupezeka ndi kufunikira, komanso mikhalidwe yotsika. Mu theka loyamba la chaka, panalibe mphamvu yatsopano yowonjezera ya mafakitale a PVC a calcium carbide m'nyumba, ndipo kuwonjezeka kwa kufunikira kwa msika wa calcium carbide kunali kochepa. N'zovuta kwa makampani a chlor-alkali omwe amagula calcium carbide kuti asunge katundu wokhazikika kwa nthawi yayitali. -
Kuphulika kunachitika mu PVC reactor ya chimphona chachikulu cha petrochemical ku Middle East!
Kampani yayikulu yamafuta ku Turkey, Petkim, yalengeza kuti madzulo a pa 19 June, 2022, kuphulika kunachitika pa fakitale ya Aliaga. Ngoziyi idachitika pa reactor ya PVC ya fakitaleyo, palibe amene adavulala, motowo unawongoleredwa mwachangu, koma chipangizo cha PVC chikhoza kukhala chopanda ntchito kwakanthawi chifukwa cha ngoziyi. Chochitikachi chikhoza kukhudza kwambiri msika wa PVC ku Europe. Akuti chifukwa mtengo wa PVC ku China ndi wotsika kwambiri kuposa wa zinthu zapakhomo ku Turkey, ndipo mtengo wa PVC ku Europe ndi wokwera kuposa wa ku Turkey, zinthu zambiri za PVC za Petkim pakadali pano zimatumizidwa ku msika waku Europe. -

Kodi utomoni wa PP ndi chiyani?
Polypropylene (PP) ndi thermoplastic yolimba, yolimba, komanso yopangidwa ndi kristalo. Imapangidwa kuchokera ku propene (kapena propylene) monomer. Utomoni wa hydrocarbon wolunjika uwu ndiye polima wopepuka kwambiri pakati pa mapulasitiki onse ogulitsa. PP imabwera ngati homopolymer kapena copolymer ndipo imatha kuwonjezeredwa kwambiri ndi zowonjezera. Polypropylene yomwe imadziwikanso kuti polypropene, ndi polima ya thermoplastic yomwe imagwiritsidwa ntchito m'njira zosiyanasiyana. Imapangidwa kudzera mu polymerization ya unyolo kuchokera ku monomer propylene. Polypropylene ndi ya gulu la polyolefins ndipo ndi crystalline pang'ono komanso yopanda polar. Kapangidwe kake ndi kofanana ndi polyethylene, koma ndi yolimba pang'ono komanso yolimba kwambiri kutentha. Ndi chinthu choyera, cholimba kwambiri ndipo chimakhala ndi kukana kwamphamvu kwa mankhwala.
