Wamenya ute niba plastiki ari polypropylene?
Bumwe mu buryo bworoshye bwo gukora ikizamini cy'umuriro ni ugukata icyitegererezo muri pulasitiki ukagishyira mu kabati k'umuriro. Ibara ry'umuriro, impumuro n'imiterere y'umuriro bishobora kwerekana ubwoko bwa pulasitiki: 1. Polyethylene (PE) - Itonyanga, impumuro nk'iy'ibishashi by'umukara; 2. Polypropylene (PP) - Itonyanga, impumuro isanzwe y'amavuta ya moteri yanduye n'iy'ibishashi by'umukara; 3. Polymethylmethacrylate (PMMA, "Perspex") - Udupira, uduce duto, impumuro nziza ihumura neza; 4. Polyamide cyangwa "Nylon" (PA) - Urumuri rw'umukara, impumuro ya marigolds; 5. Acrylonitrilebutadienestyrene (ABS) - Urumuri rudasobanutse, rudafite ubushyuhe, impumuro ya marigolds; 6. Polyethylene foam (PE) - Itonyanga, impumuro ya bishashi by'umukara -
Mars M Beans yashyize ahagaragara impapuro za PLA zishobora kubora mu Bushinwa.
Mu 2022, Mars yashyize ahagaragara shokora ya mbere ya M&M ipakiye mu mpapuro zishobora kwangirika mu Bushinwa. Ikozwe mu bikoresho bishobora kwangirika nk'impapuro na PLA, bisimbura ipaki gakondo ya pulasitiki yoroshye mu bihe byashize. Ipaki yanyuze muri GB/T. Uburyo bwo kugena ifumbire bwo mu 19277.1 bwemeje ko mu gihe cyo gukora ifumbire y'imborera mu nganda, ishobora kwangirika ku kigero kirenga 90% mu mezi 6, kandi ikaba amazi atari uburozi mu binyabuzima, dioxyde de carbone n'ibindi bicuruzwa nyuma yo kwangirika. -
Ibicuruzwa bya PVC byoherezwa mu mahanga mu Bushinwa biracyari hejuru mu gice cya mbere cy'umwaka.
Dukurikije imibare iheruka ya gasutamo, muri Kamena 2022, ingano y'ifu ya PVC yo mu gihugu cyanjye yari toni 29.900, yiyongereyeho 35.47% ugereranyije n'ukwezi gushize n'izamuka rya 23.21% ugereranyije n'umwaka ushize; muri Kamena 2022, ingano y'ifu ya PVC yo mu gihugu cyanjye yoherezwa mu mahanga yari toni 223.500, igabanuka ry'ukwezi kwa buri kwezi ryari 16%, naho izamuka ry'umwaka ryabaye 72.50%. Ingano y'iyoherezwa mu mahanga yakomeje kuguma ku rwego rwo hejuru, byagabanyije ubwinshi bw'ibicuruzwa ku isoko ry'imbere mu gihugu ku rugero runaka. -
Polypropylene (PP) ni iki?
Polypropylene (PP) ni thermoplastic ikomeye, ikomeye kandi ikoze muri kristu. Ikozwe muri monomer ya propene (cyangwa propylene). Iyi resin ya hydrocarbon iri ku murongo ni polymer yoroshye cyane mu zindi pulasitiki zose zikoreshwa. PP iza nka homopolymer cyangwa nka copolymer kandi ishobora kongerwamo cyane hamwe n'inyongera. Ikoreshwa mu gupfunyika, mu modoka, mu bicuruzwa bicuruzwa, mu buvuzi, mu mafirime ya filime, nibindi. PP yabaye ibikoresho bikundwa cyane, cyane cyane iyo ushaka polymer ikomeye cyane (urugero, ugereranije na Polyamide) mu bikorwa by'ubuhanga cyangwa ushakisha inyungu mu macupa yo gushushanya (ugereranije na PET). -
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. -
Inama ya Chemdo ya mu gitondo ku ya 26 Nyakanga.
Mu gitondo cyo ku ya 26 Nyakanga, Chemdo yakoranye inama rusange. Mu ntangiriro, umuyobozi mukuru yagaragaje ibitekerezo bye ku miterere y'ubukungu muri iki gihe: ubukungu bw'isi buri hasi, inganda zose z'ubucuruzi bw'amahanga ziragabanuka, icyifuzo kirimo kugabanuka, kandi igipimo cy'imizigo yo mu mazi kirimo kugabanuka. Kandi wibutse abakozi ko mu mpera za Nyakanga, hari ibibazo byihariye bigomba gukemurwa, bishobora gutegurwa vuba bishoboka. Kandi yagennye insanganyamatsiko ya videwo nshya y'iki cyumweru: Ihungabana rikomeye mu bucuruzi bw'amahanga. Hanyuma yatumiye bagenzi be benshi gusangira amakuru agezweho, kandi amaherezo asaba ishami ry'imari n'inyandiko kubika neza inyandiko. -
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.
