Polyethylene (PE) ni iki?
Polyethylene (PE), izwi kandi nka polythene cyangwa polyethene, ni imwe muri pulasitiki zikoreshwa cyane ku isi. Polyethylene akenshi igira imiterere igororotse kandi izwiho kuba polymeri zongewemo. Ikoreshwa ry'ibanze ry'izi polymeri zikoze mu buryo bwa sintetike ni mu gupfunyika. Polyethelyne ikunze gukoreshwa mu gukora imifuka ya pulasitiki, amacupa, amafirime ya pulasitiki, ibikoresho, n'ibipimo bya geomembrane. Byaragaragaye ko toni zirenga miliyoni 100 za polyethene zikorwa buri mwaka mu rwego rw'ubucuruzi n'inganda. -
Isesengura ry'imikorere y'isoko ry'ibicuruzwa byoherezwa mu mahanga bya PVC mu gihugu cyanjye mu gice cya mbere cya 2022.
Mu gice cya mbere cya 2022, isoko ry’ibicuruzwa byoherezwa mu mahanga bya PVC ryiyongereye uko umwaka utashye. Mu gihembwe cya mbere, cyagizweho ingaruka n’ihungabana ry’ubukungu ku isi n’icyorezo, amasosiyete menshi yo mu gihugu atumiza mu mahanga yagaragaje ko icyifuzo cya disiki zo hanze cyagabanutse cyane. Ariko, kuva mu ntangiriro za Gicurasi, hamwe n’izamuka ry’ikibazo cy’icyorezo n’ingamba zitandukanye zashyizweho na guverinoma y’Ubushinwa zo gushishikariza ubukungu kuzahura, igipimo cy’imikorere y’ibigo bitunganya PVC byo mu gihugu cyariyongereye cyane, isoko ry’ibicuruzwa byoherezwa mu mahanga bya PVC ryariyongereye, kandi icyifuzo cya disiki zo hanze cyariyongereye. Umubare werekana ko hari intambwe y’iterambere, kandi umusaruro w’isoko muri rusange wariyongereye ugereranije n’igihe cyashize. -
PVC ikoreshwa mu ki?
Polyvinyl chloride (PVC, cyangwa vinyl) ihendutse kandi ikoreshwa mu buryo butandukanye mu nyubako no mu bwubatsi, mu buvuzi, mu by'ikoranabuhanga, mu modoka no mu bindi bice, mu bicuruzwa bitandukanye kuva ku miyoboro n'ibice by'amazi, mu mifuka y'amaraso no mu miyoboro, kugeza ku byuma bikingira insinga n'insinga, ibice by'ibirahuri by'imbere n'ibindi. -
Umushinga wo kwagura ethylene no gutunganya amashanyarazi wa Hainan Refinery utwaye toni miliyoni ugiye gutangwa.
Umushinga wo gutunganya no kwagura amashanyarazi wa Hainan hamwe n'umushinga wo kongera kubaka no kwagura amashanyarazi biherereye mu gace k'iterambere ry'ubukungu ka Yangpu, aho ishoramari rya miliyari zisaga 28 z'amayuan. Kugeza ubu, iterambere ry'ubwubatsi muri rusange ryageze kuri 98%. Nyuma y'uko umushinga urangiye kandi ugashyirwa mu bikorwa, biteganijwe ko uzatwara inganda zisaga miliyari 100 z'amayuan. Inama ya Olefin Feedstock Diversification na High-end Downstream izabera i Sanya ku ya 27-28 Nyakanga. Muri iki gihe gishya, iterambere ry'imishinga minini nka PDH, na ethane cracking, icyerekezo cy'ikoranabuhanga rishya mu gihe kizaza nka peteroli ijya muri olefin, no kongera umusaruro mushya w'amakara/methanol muri olefin. -
MIT: Uduce duto twa copolymer duto twa polylactic-glycolic acid dukora urukingo "rwiyongera".
Abahanga mu bya siyansi bo mu kigo cy’ikoranabuhanga cya Massachusetts (MIT) batangaje mu kinyamakuru giherutse cya Science Advances ko barimo gukora urukingo rumwe rwo kwiyongerera imbaraga. Nyuma y’uko urukingo rushyizwe mu mubiri w’umuntu, rushobora gusohoka inshuro nyinshi nta mpamvu yo kurutera. Biteganijwe ko uru rukingo rushya ruzakoreshwa mu kurwanya indwara kuva kuri measles kugeza kuri Covid-19. Bivugwa ko uru rukingo rushya rukozwe mu bice bya poly (lactic-co-glycolic acid) (PLGA). PLGA ni ikintu cy’umwimerere cya polymer gishobora kwangirika, kidahumanya kandi gifite ubushobozi bwo guhuza neza n’ibinyabuzima. Yemejwe gukoreshwa mu gutera imiti, gukurura, ibikoresho byo gusana, nibindi. -
Yuneng Chemical Company: Umusaruro wa mbere wa polyethylene ikoreshwa mu nganda!
Vuba aha, ishami rya LLDPE rya Polyolefin Center of Yuneng Chemical Company ryakoze neza DFDA-7042S, igikoresho cya polyethylene gishobora gusukwa. Birumvikana ko igikoresho cya polyethylene gishobora gusukwa ari igikoresho gikomoka ku iterambere ryihuse ry'ikoranabuhanga ryo gutunganya ibintu. Ibikoresho bya polyethylene byihariye bifite ubushobozi bwo gusukwa hejuru bikemura ikibazo cy'imikorere mibi y'irangi rya polyethylene kandi bifite ibara ryinshi. Iki gikoresho gishobora gukoreshwa mu mirimo yo gushushanya no kurinda, kibereye ibikoresho by'abana, imbere mu modoka, ibikoresho byo gupakira, ndetse n'ibigega binini byo kubikamo ibikoresho by'inganda n'ubuhinzi, ibikinisho, inzira zo kurinda imihanda, nibindi, kandi isoko ni rinini cyane. -
Toni miliyoni 1.65 za polyolefin za Petronas zigiye kugaruka ku isoko rya Aziya!
Nk’uko amakuru aheruka abivuga, Pengerang muri Johor Bahru, muri Maleziya, yongeye gutangiza icyuma cyayo cya polyethylene yo mu bwoko bwa linear low-density (LLDPE) cya toni 350.000 ku mwaka ku ya 4 Nyakanga, ariko icyuma gishobora gufata igihe kugira ngo kigere ku mikorere ihamye. Uretse ibyo, ikoranabuhanga rya Spheripol rya toni 450.000 ku mwaka uruganda rwa polypropylene (PP), toni 400.000 ku mwaka uruganda rwa polyethylene yo mu bwoko bwa high-density (HDPE) n’ikoranabuhanga rya Spherizone rya toni 450.000 ku mwaka uruganda rwa polypropylene (PP) nabyo biteganijwe ko bizazamuka uhereye muri uku kwezi kugira ngo bitangire. Nk’uko Argus yabitangaje, igiciro cya LLDPE muri Aziya y’Amajyepfo y’uburasirazuba nta musoro ku ya 1 Nyakanga ni $1360-1380/toni CFR, naho igiciro cya PP insinga muri Aziya y’Amajyepfo y’uburasirazuba ku ya 1 Nyakanga ni $1270-1300/toni CFR nta musoro. -
Isegereti zihinduka zikoresha ipakira rya pulasitiki ribora mu Buhinde.
Guhagarika kwa pulasitiki 19 zikoreshwa rimwe mu Buhinde byatumye habaho impinduka mu nganda z’itabi. Mbere ya 1 Nyakanga, inganda zikora itabi mu Buhinde zari zarahinduye uburyo bwazo bwo gupakira pulasitiki zisanzwe zikoreshwa mu gupakira pulasitiki zishobora kubora. Ikigo cy’itabi mu Buhinde (TII) kivuga ko abanyamuryango bacyo bahinduwe kandi ko pulasitiki zishobora kubora zikoreshwa zujuje ibisabwa mpuzamahanga, ndetse n’amahame ya BIS aherutse gusohoka. Bavuga kandi ko kubora kwa pulasitiki zishobora kubora bitangirana n’ubutaka kandi bigahinduka mu buryo busanzwe mu gufumbira ifumbire mvaruganda nta guhangayikishwa no gukusanya imyanda ikomeye no kuyikoresha mu kongera kuyikoresha. -
Isesengura rigufi ry'imikorere y'isoko rya karuboni ya kalisiyumu mu gihugu mu gice cya mbere cy'umwaka.
Mu gice cya mbere cya 2022, isoko rya karuboni ya karuboni mu gihugu ntiryakomeje kuzamuka cyane mu 2021. Isoko muri rusange ryari hafi y’umubare w’ibiciro, kandi ryahuye n’ihindagurika ry’ibiciro bitewe n’ingaruka z’ibikoresho fatizo, itangwa n’ibikenewe, ndetse n’imimerere yo kuzamuka. Mu gice cya mbere cy’umwaka, nta bushobozi bushya bwo kwagura inganda za PVC zikora karuboni ya karuboni mu gihugu, kandi ukwiyongera kw’ibikenewe ku isoko rya karuboni ya karuboni byari bike. Biragoye ku bigo bicuruza karuboni ya chlor-alkali bigura karuboni ya karuboni kugira ngo bikomeze umutwaro uhamye igihe kirekire. -
Iturika ryabaye mu cyuma gitunganya peteroli cya PVC mu Burasirazuba bwo Hagati!
Petkim, ikigo gikomeye cyo muri Turukiya gicuruza peteroli, yatangaje ko ku mugoroba wo ku ya 19 Kamena 2022, habaye iturika ku ruganda rwa Aliaga.

Gushyira insinga za aside polylactic ku myambaro y'ishuri.
Fengyuan Bio-Fiber yafatanyije na Fujian Xintongxing gushyira fibre ya aside polylactic ku myenda yo kwambara ku ishuri. Imikorere yayo myiza yo kwinjiza ubushuhe no kubira ibyuya ikubye inshuro 8 ugereranyije n'imyenda isanzwe ya polyester. Fibre ya PLA ifite ubushobozi bwo kurwanya bagiteri kurusha izindi myenda iyo ari yo yose. Ubushobozi bwo kwihanganira ubushuhe bugera kuri 95%, buruta cyane izindi myenda iyo ari yo yose ya shimi. Byongeye kandi, umwenda ukozwe muri fibre ya aside polylactic ni mwiza ku ruhu kandi ntushobora guhumeka, ushyushye kandi uhumeka, kandi ushobora no gukumira bagiteri n'udukoko, kandi ukaba urinda umuriro kandi urinda umuriro. Imyenda y'ishuri ikozwe muri uyu mwenda irushaho kurengera ibidukikije, itekanye kandi yoroshye.
