Mpaka pano, ntchito yomanga yonse yafika pa 98%. Ntchitoyi ikamalizidwa ndikupangidwa, ikuyembekezeka kuyendetsa mayuan opitilira 100 biliyoni amakampani akumunsi. Olefin Feedstock Diversification ndi High-end Downstream Forum idzachitikira ku Sanya pa July 27-28. Pansi pa zinthu zatsopano, chitukuko cha ntchito zazikulu monga PDH, ndi ethane cracking, mchitidwe wamtsogolo wa matekinoloje atsopano monga mafuta osakanizidwa mwachindunji ku olefins, ndi mbadwo watsopano wa malasha / methanol ku olefins udzakambidwa. pa -
MIT: Polylactic-glycolic acid copolymer microparticles amapanga katemera "wodzikulitsa".
Asayansi ku Massachusetts Institute of Technology (MIT) lipoti m’magazini yaposachedwapa Science Advances kuti akupanga katemera wa mlingo umodzi wodzilimbitsa okha. Katemera akabayidwa m'thupi la munthu, amatha kutulutsidwa kangapo popanda kufunikira kowonjezera. Katemera watsopanoyu akuyembekezeka kugwiritsidwa ntchito polimbana ndi matenda kuyambira chikuku mpaka Covid-19. Akuti katemera watsopanoyu amapangidwa ndi tinthu ting'onoting'ono ta poly(lactic-co-glycolic acid) (PLGA). PLGA ndi chinthu chowonongeka chogwira ntchito polima organic, chomwe chilibe poizoni ndipo chimakhala ndi kuyanjana kwabwino. Zavomerezedwa kuti zigwiritsidwe ntchito mu Implants, sutures, kukonza zida, etc -
Yuneng Chemical Company: Kupanga koyamba kwamafakitale kwa polyethylene yopopera!
Posachedwapa, gawo la LLDPE la Polyolefin Center la Yuneng Chemical Company linapanga bwino DFDA-7042S, mankhwala opangidwa ndi polyethylene. Zikumveka kuti sprayable polyethylene mankhwala ndi mankhwala anachokera ku chitukuko mofulumira kutsetsereka processing luso. Zapadera za polyethylene zokhala ndi kupopera mbewu mankhwalawa pamwamba zimathetsa vuto la mtundu wa polyethylene wonyezimira komanso wonyezimira kwambiri. Mankhwalawa angagwiritsidwe ntchito m'minda yokongoletsera ndi chitetezo, yoyenera kwa ana, mkati mwa galimoto, zipangizo zonyamula katundu, komanso akasinja akuluakulu osungiramo mafakitale ndi zaulimi, zoseweretsa, zosungira misewu, ndi zina zotero, ndipo chiyembekezo cha msika ndi chachikulu kwambiri. pa -

Malinga ndi kuwunika kwa Argus, mtengo wa LLDPE ku Southeast Asia popanda msonkho pa Julayi 1 ndi US$1360-1380/tani CFR, ndipo mtengo wa PP wire kujambula ku Southeast Asia pa Julayi 1 ndi US$1270-1300/tani CFR popanda msonkho. -
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 umakhala ndi kusinthasintha ndi kusintha chifukwa cha kukhudzidwa kwa zipangizo, kupezeka ndi kufunikira, ndi mikhalidwe yotsika. 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 choyatsira cha PVC cha chimphona cha petrochemical ku Middle East!

PP resin ndi chiyani?
Polypropylene (PP) ndi thermoplastic yolimba, yolimba, komanso yonyezimira. Amapangidwa kuchokera ku propene (kapena propylene) monomer. Utoto wa hydrocarbon uyu ndiye polima wopepuka kwambiri pakati pa mapulasitiki onse ogulitsa. PP imabwera ngati homopolymer kapena ngati copolymer ndipo imatha kulimbikitsidwa kwambiri ndi zowonjezera. Polypropylene yomwe imadziwikanso kuti polypropene, ndi polima ya thermoplastic yomwe imagwiritsidwa ntchito m'njira zosiyanasiyana. Amapangidwa kudzera mu unyolo-kukula kwa polymerization kuchokera ku propylene monoma. Makhalidwe ake ndi ofanana ndi polyethylene, koma ndizovuta pang'ono komanso zosagwirizana ndi kutentha. Ndi chinthu choyera, chopangidwa ndi makina ndipo chimakhala ndi kukana kwa mankhwala.
