MIT: Microparticles ya polylactique-glycolike ikora urukingo "rwiyongera".
Abashakashatsi bo mu Ishuri Rikuru ry’ikoranabuhanga rya Massachusetts (MIT) batangaza mu kinyamakuru Science Advances giherutse kuvuga ko barimo gukora urukingo rumwe rukumbi rwiyongera.Urukingo rumaze guterwa mumubiri wumuntu, rushobora kurekurwa inshuro nyinshi bidakenewe kurasa.Biteganijwe ko urukingo rushya ruzakoreshwa mu kurwanya indwara kuva iseru kugeza Covid-19.Biravugwa ko uru rukingo rushya rukozwe mu bice bya poly (lactique-co-glycolique) (PLGA).PLGA ni imikorere yimikorere ya polymer organic compound, idafite uburozi kandi ifite biocompatibilité nziza.Byemejwe gukoreshwa muri Implants, suture, ibikoresho byo gusana, nibindi. -
Uruganda rukora imiti rwa Yuneng: Umusaruro wambere winganda za polyethylene ziterwa!
Vuba aha, ishami rya LLDPE ryikigo cya Polyolefin cyikigo cyimiti cya Yuneng cyakoze neza DFDA-7042S, ibicuruzwa biterwa na polyethylene.Byumvikane ko igiti gishobora guterwa polyethylene nigicuruzwa gikomoka ku iterambere ryihuse ryiterambere rya tekinoroji yo hasi.Ibikoresho bidasanzwe bya polyethylene hamwe no gutera spray hejuru bikemura ikibazo cyimikorere mibi yamabara ya polyethylene kandi ifite gloss nyinshi.Ibicuruzwa birashobora gukoreshwa mubice byo gushushanya no kurinda, bikwiranye nibicuruzwa byabana, imbere yimodoka, ibikoresho byo gupakira, hamwe n’ibigega binini byo mu nganda n’ubuhinzi, ibikinisho, kurinda umuhanda, nibindi, kandi ibyifuzo byisoko ni byinshi cyane. -
Petronas toni miliyoni 1.65 za polyolefin iri hafi gusubira ku isoko rya Aziya!
Nk’uko amakuru aheruka kubitangaza, ku ya 4 Nyakanga, Pengerang i Johor Bahru, muri Maleziya, yongeye gutangiza igice cyayo cya toni 350.000 / yumurongo wa polyethylene (LLDPE), ariko igice gishobora gufata igihe kugira ngo kigere ku bikorwa bihamye.Uretse ibyo, ikoranabuhanga ryayo rya Spheripol toni 450.000 / ku mwaka uruganda rwa polypropilene (PP), toni 400.000 / ku mwaka uruganda rwinshi rwa polyethylene (HDPE) hamwe n’ikoranabuhanga rya Spherizone toni 450.000 / ku mwaka uruganda rwa polypropilene (PP) narwo ruteganijwe kwiyongera kuva muri uku kwezi kugira ngo rutangire.Dukurikije isuzuma rya Argus, igiciro cya LLDPE mu majyepfo y’iburasirazuba bwa Aziya nta musoro ku ya 1 Nyakanga ni US $ 1360-1380 / toni CFR, naho igiciro cy’insinga za PP zishushanya mu majyepfo y’iburasirazuba bwa Aziya ku ya 1 Nyakanga ni US $ 1270-1300 / toni CFR nta musoro . -
Itabi rihinduka mububiko bwa pulasitike ibora mu Buhinde.
Ubuhinde bwabujije plastike 19 zikoreshwa rimwe gusa byatumye impinduka z’inganda z’itabi.Mbere y'itariki ya 1 Nyakanga, abakora itabi mu Buhinde bari barahinduye ibikoresho bisanzwe bya pulasitiki babipakira babipakira.Ikigo cy’itabi ry’Ubuhinde (TII) kivuga ko abayoboke babo bahinduwe kandi plastiki y’ibinyabuzima ishobora gukoreshwa yujuje ubuziranenge mpuzamahanga, ndetse n’ibipimo BIS iherutse gutanga.Bavuga kandi ko ibinyabuzima byangiza ibinyabuzima bitangiza ibinyabuzima bitangira guhura n’ubutaka ndetse na biodegrade bisanzwe mu ifumbire mvaruganda nta gushimangira gukusanya imyanda ikomeye ndetse n’uburyo bwo kuyitunganya. -
Isesengura Muri make Imikorere y'Isoko rya Kalisiyumu yo mu Gihugu mu gice cya mbere cy'umwaka.
Mu gice cya mbere cya 2022, isoko rya kariside ya calcium yo mu gihugu ntiyakomeje inzira ihindagurika mu 2021. Isoko rusange ryari hafi y’umurongo w’ibiciro, kandi ryagombaga guhindagurika no guhinduka bitewe n’ingaruka z’ibikoresho fatizo, itangwa n’ibisabwa. , hamwe no kumanuka.Mu gice cya mbere cyumwaka, nta bushobozi bushya bwo kwagura uburyo bwa calcium karbide yo mu gihugu bwa PVC, kandi kwiyongera kwa calcium karbide ku isoko byari bike.Biragoye kubigo bya chlor-alkali bigura kariside ya calcium kugirango igumane umutwaro uhamye mugihe kirekire. -
Igisasu cyaturikiye muri reaction ya PVC yikinini cya peteroli mu burasirazuba bwo hagati!
Igihangange cya peteroli ya Turukiya Petkim yatangaje ko ku mugoroba wo ku ya 19 Kamena 2022, igisasu cyaturikiye ku ruganda rwa Aliaga.impanuka yabereye mumashanyarazi ya PVC y'uruganda, ntamuntu wakomeretse, umuriro wagenzuwe vuba, ariko ishami rya PVC rishobora kuba kumurongo wigihe gito kubera impanuka.Ibirori birashobora kugira ingaruka zikomeye kumasoko yuburayi ya PVC.Biravugwa ko kubera ko igiciro cya PVC mu Bushinwa kiri hasi cyane ugereranije n’ibicuruzwa byo mu gihugu cya Turukiya, kandi igiciro cy’ibicuruzwa bya PVC mu Burayi kiri hejuru ugereranije no muri Turukiya, ibicuruzwa byinshi bya PVC bya Petkim byoherezwa ku isoko ry’Uburayi. -

Ku ya 30 Kamena 2022, BASF hamwe n’uruganda rukora ibicuruzwa byo muri Ositaraliya Confoil bafatanyijemo gukora ifumbire mvaruganda yemewe, ifasha-ifuru-ifungura impapuro zangiza ibiryo - DualPakECO®.Imbere yimpapuro zometseho ecovio® ya BASF ya PS1606, ikora cyane-rusange-intego-ya bioplastique yubucuruzi yakozwe na BASF.Ni plastiki ishobora kuvugururwa ibinyabuzima (ibirimo 70%) ivanze nibicuruzwa bya ecoflex ya BASF na PLA, kandi ikoreshwa muburyo bwo gukora ibifuniko byo gupakira impapuro cyangwa amakarito.Bafite inzitizi nziza ku binure, amavuta n'impumuro kandi birashobora kubika imyuka ihumanya ikirere. -
Gukoresha fibre acide polylactique kumyambaro yishuri.
Fengyuan Bio-Fibre yakoranye na Fujian Xintongxing gukoresha fibre acide polylactique mumyenda yo kwishuri.Igikorwa cyacyo cyiza cyane cyo kwinjiza no kubira ibyuya nikubye inshuro 8 icyuma gisanzwe cya polyester.Fibre ya PLA ifite antibacterial nziza cyane kuruta izindi fibre.Kurwanya imbaraga za fibre bigera kuri 95%, bikaba byiza cyane kurenza izindi fibre chimique.Byongeye kandi, igitambaro gikozwe muri fibre acide polylactique cyangiza uruhu kandi ntigishobora kugira ubushyuhe, gishyuha kandi gihumeka, kandi gishobora no kubuza bagiteri na mite, kandi kikaba cyirinda umuriro kandi kikirinda umuriro.Imyambaro yishuri ikozwe muriyi myenda irushaho kubungabunga ibidukikije, umutekano kandi neza. -
Ikibuga cy'indege cya Nanning: Kuraho ibitagenda neza, nyamuneka winjire
Ikibuga cy'indege cya Nanning cyasohoye “Amabwiriza agenga ikibuga cya Nanning cyo gukumira no gukumira ibicuruzwa” kugira ngo biteze imbere ishyirwa mu bikorwa ry’igenzura ry’imyanda ihumanya ikirere.Kugeza ubu, ibicuruzwa byose bya pulasitiki bidashobora kwangirika byasimbuwe n’ubundi buryo bwangirika mu masoko manini, muri resitora, aho abantu baruhukira abagenzi, aho imodoka zihagarara ndetse n’ahandi mu nyubako ya gari ya moshi, kandi indege zitwara abagenzi mu gihugu zahagaritse gutanga ibyatsi bya pulasitiki bidashobora kwangirika, bikurura inkoni. , gupakira imifuka, koresha ibicuruzwa byangiritse cyangwa ubundi buryo.Menya neza "gukuraho" ibicuruzwa bya pulasitiki bitangirika, kandi "nyamuneka winjire" kubindi bidukikije byangiza ibidukikije. -
PP resin ni iki?
Polypropilene (PP) nikintu gikomeye, gikomeye, kandi kristaline.Ikozwe muri propene (cyangwa propylene) monomer.Uyu murongo wa hydrocarbon resin ni polymer yoroheje muri plastiki y'ibicuruzwa byose.PP ije nka homopolymer cyangwa nka copolymer kandi irashobora kuzamurwa cyane ninyongera.Polypropilene izwi kandi nka polypropene, ni polymer ya termoplastique ikoreshwa muburyo butandukanye bwo gukoresha.Ikorwa hifashishijwe urunigi-rukura polymerisiyumu kuva monomer propylene.Polypropilene ni iyitsinda rya polyolefine kandi ni kristaline igice kandi itari polar.Imiterere yacyo isa na polyethylene, ariko irakomeye gato kandi irwanya ubushyuhe.Nibikoresho byera, byubatswe kandi bifite imiti myinshi irwanya imiti. -
