Sinopec, PetroChina n'abandi basabye kubushake bwo kuva kurutonde rwabanyamerika!
Nyuma yo gutondekanya CNOOC ku Isoko ry’imigabane rya New York, amakuru aheruka ni uko ku gicamunsi cyo ku ya 12 Kanama, PetroChina na Sinopec bakomeje gutanga amatangazo bavuga ko bateganya kuvanaho imigabane yo kubitsa muri Amerika ku isoko ry’imigabane rya New York. Byongeye kandi, Sinopec Shanghai Petrochemical, Ubwishingizi bw'Ubuzima mu Bushinwa, hamwe na Aluminum Corporation yo mu Bushinwa na bo bagiye batanga amatangazo bavuga ko bafite umugambi wo kuvanaho imigabane yo kubitsa muri Amerika mu Isoko ry'imigabane rya New York. Nk’uko byatangajwe n’isosiyete ibishinzwe, aya masosiyete yubahirije byimazeyo amategeko agenga isoko ry’imari muri Leta zunze ubumwe z’Amerika ndetse n’ibisabwa kugira ngo agenzurwe kuva yatangazwa muri Leta zunze ubumwe z’Amerika, kandi guhitamo kurutonde byaturutse ku bitekerezo byabo bwite. -
Isi ya mbere ya PHA floss yatangijwe！
Ku ya 23 Gicurasi, ikirango cy’amenyo y’abanyamerika cyitwa Plackers®, cyashyize ahagaragara EcoChoice Compostable Floss, icyatsi cy’amenyo kirambye gishobora kwangirika 100% mu rugo rw’ifumbire mvaruganda. EcoChoice Ifumbire mvaruganda ikomoka muri PHA ya Danimer Scientific, biopolymer ikomoka ku mavuta ya canola, indabyo za silike karemano hamwe nuduseke twa cocout. Indabyo nshya ifumbire mvaruganda yuzuza EcoChoice ihoraho yinyo y amenyo. Ntabwo zitanga gusa ibikenerwa byo guterwa, ahubwo binagabanya amahirwe yo kuba plastiki zijya mu nyanja n’imyanda. -
Isesengura kumiterere yiterambere ryinganda za PVC muri Amerika ya ruguru.
Amerika y'Amajyaruguru n'akarere ka kabiri mu bunini bwa PVC ku isi. Muri 2020, umusaruro wa PVC muri Amerika ya ruguru uzaba toni miliyoni 7.16, bingana na 16% by’umusaruro wa PVC ku isi. Mu bihe biri imbere, umusaruro wa PVC muri Amerika ya Ruguru uzakomeza gukomeza kuzamuka. Amerika ya Ruguru nicyo gihugu kinini cyohereza ibicuruzwa hanze muri PVC, bingana na 33% by’ubucuruzi bw’ibicuruzwa byoherezwa mu mahanga PVC ku isi. Ingaruka zitangwa bihagije muri Amerika ya Ruguru ubwayo, ibicuruzwa bitumizwa mu mahanga ntibiziyongera cyane mu gihe kiri imbere. Muri 2020, ikoreshwa rya PVC muri Amerika y'Amajyaruguru ni toni miliyoni 5.11, muri zo hafi 82% zikaba ziri muri Amerika. Amajyaruguru ya Amerika ya PVC akoreshwa cyane cyane mugutezimbere isoko ryubwubatsi. -
Niki HDPE ikoreshwa?
HDPE ikoreshwa mubicuruzwa no gupakira nk'ibikombe by'amata, amacupa yo kumesa, imiyoboro ya margarine, ibikoresho by'imyanda hamwe n'imiyoboro y'amazi. Mubitereko byuburebure butandukanye, HDPE ikoreshwa nkigisimbuza amakarito yatanzwe namakarito yatanzwe kubwimpamvu ebyiri zibanze. Imwe, ni umutekano cyane kuruta amakarito yatanzwe kuko niba igikonoshwa cyarakoze nabi kigaturika imbere muri tube ya HDPE, umuyoboro ntuzavunika. Impamvu ya kabiri ni uko bongeye gukoreshwa bemerera abashushanya gukora ibisasu byinshi bya minisiteri. Pyrotechnicien iraca intege ikoreshwa rya PVC mu miyoboro ya minisiteri kuko ikunda kumeneka, ikohereza ibice bya pulasitike kubantu bashobora kureba, kandi ntibizagaragara muri X-ray. ? -
Ikarita yicyatsi ya PLA ihinduka igisubizo kirambye cyinganda zimari.
Harakenewe plastike nyinshi cyane kugirango amakarita ya banki buri mwaka, kandi hamwe n’ibibazo by’ibidukikije bigenda byiyongera, Thales, umuyobozi mu mutekano w’ikoranabuhanga rikomeye, yashyizeho igisubizo. Kurugero, ikarita ikozwe muri 85% acide polylactique (PLA), ikomoka mubigori; ubundi buryo bushya ni ugukoresha tissue kuva mubikorwa byo gusukura inkombe binyuze mubufatanye nitsinda ryibidukikije Parley kubinyanja. Imyanda yakusanyirijwe hamwe - “Inyanja Plastike®” nk'ibikoresho bishya bigezweho byo gukora amakarita; hari kandi uburyo bwo gukoresha amakarita ya PVC yongeye gukoreshwa bikozwe muri plastiki yimyanda iva mu nganda zipakira no gucapa kugirango ugabanye ikoreshwa rya plastiki nshya. ? -
Isesengura rigufi ryubushinwa paste pvc resin itumizwa no kohereza hanze kuva Mutarama kugeza Kamena.
Kuva muri Mutarama kugeza muri Kamena 2022, igihugu cyanjye cyatumije toni 37,600 zose z’ibisigazwa bya paste, byagabanutseho 23% ugereranije n’icyo gihe cyashize umwaka ushize, kandi byohereje toni 46.800 z’ibiti bya paste, byiyongeraho 53.16% ugereranije n’icyo gihe cyashize umwaka ushize. Mu gice cya mbere cy’umwaka, usibye ibigo ku giti cye byahagaritswe kugira ngo bibungabunge, uruganda rukora imiti y’imbere mu gihugu rwagumye ku rwego rwo hejuru, ibicuruzwa byari bihagije, kandi isoko ryakomeje kugabanuka. Abakora ibicuruzwa bashakishaga ibicuruzwa byoherezwa mu mahanga kugira ngo bakemure amakimbirane yo mu gihugu imbere, kandi ibicuruzwa byoherezwa mu mahanga byiyongereye ku buryo bugaragara. -
Nigute ushobora kumenya niba plastike ari polypropilene?
Bumwe mu buryo bworoshye bwo gukora ikizamini cya flame ni ugukata icyitegererezo muri plastiki ukagitwika mu kabati ka fume. Ibara ry'umuriro, impumuro n'ibiranga gutwika birashobora gutanga kwerekana ubwoko bwa plastiki: 1. Polyethylene (PE) - Ibitonyanga, impumuro nka buji ； 2.Polypropilene (PP) - Ibitonyanga, impumuro nziza yamavuta ya moteri yanduye hamwe na buji ya le 3. Polymethylmethacrylate (PMMA, cyangwa “Nylon” (PA) - Umuriro wa Sooty, impumuro ya marigolds ； 5. Acrylonitrilebutadienestyrene (ABS) - Ntabwo ari mucyo, urumuri rutuje, impumuro ya marigolds ； 6. Ifuro rya polyethylene (PE) - Ibitonyanga, impumuro ya buji. -
Mars M Ibishyimbo byatangije ibinyabuzima byangiza PLA bipfunyika mubushinwa.
Mu 2022, Mars yashyize ahagaragara shokora ya mbere ya M & M ipakiye mu mpapuro zangirika mu Bushinwa. Ikozwe mubikoresho byangirika nkimpapuro na PLA, bisimbuza ibipfunyika bya pulasitiki byoroshye byahise. Gupakira byanyuze kuri GB / T Uburyo bwo kugena 19277.1 bwagenzuye ko mugihe cyo gufumbira inganda, bishobora kwangirika hejuru ya 90% mumezi 6, kandi bizahinduka amazi yubumara butari mubinyabuzima, dioxyde de carbone nibindi bicuruzwa nyuma yo kwangirika. ? -
Ubushinwa bwa PVC bwohereza ibicuruzwa bukomeje kuba hejuru mu gice cya mbere cyumwaka.
Nk’uko imibare iheruka ya gasutamo ibigaragaza, muri Kamena 2022, igihugu cyanjye cyatumije mu mahanga ifu y’ifu ya PVC yari toni 29.900, ikiyongeraho 35.47% ugereranije n’ukwezi gushize naho umwaka ushize ikiyongera 23.21%; muri Kamena 2022, igihugu cyanjye cya PVC cyuzuye ifu yuzuye yoherezwa mu mahanga yari toni 223.500, Ukwezi kugabanuka ku kwezi kwari 16%, naho umwaka ushize kwiyongera ni 72.50%.

Polypropilene (PP) 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. Irasanga porogaramu mubipfunyika, ibinyabiziga, umuguzi mwiza, ubuvuzi, firime za firime, nibindi PP yahindutse ibikoresho byo guhitamo, cyane cyane mugihe ushakisha polymer ifite imbaraga zisumba izindi (urugero, vs Polyamide) mubikorwa bya injeniyeri cyangwa ushakisha gusa inyungu yibiciro mumacupa yibumba (v. PET). -
Polyethylene (PE) ni iki?
Polyethylene (PE), izwi kandi nka polythene cyangwa polyethene, ni imwe muri plastiki zikoreshwa cyane ku isi. Polyethylene mubusanzwe ifite umurongo ugaragara kandi bizwi ko wongeyeho polymers. Porogaramu yibanze yiyi polimeri yubukorikori iri mubipfunyika. Polyethelyne ikoreshwa kenshi mugukora imifuka ya pulasitike, amacupa, firime ya plastike, kontineri, na geomembranes. Twabibutsa ko toni zisaga miliyoni 100 za polyethene zikorwa buri mwaka hagamijwe ubucuruzi n’inganda. -
Isesengura ryimikorere yigihugu cyanjye PVC yohereza ibicuruzwa hanze mugice cya mbere cya 2022.
Mu gice cya mbere cya 2022, isoko rya PVC ryohereza ibicuruzwa ryiyongereye umwaka-ku-mwaka. Mu gihembwe cya mbere, cyatewe n’ubukungu bwifashe nabi ku isi ndetse n’icyorezo, amasosiyete menshi yohereza mu mahanga mu gihugu yerekanye ko icyifuzo cya disiki zo hanze cyagabanutse. Icyakora, kuva mu ntangiriro za Gicurasi, hamwe n’iterambere ry’icyorezo hamwe n’ingamba zafashwe na guverinoma y’Ubushinwa mu rwego rwo gushimangira ubukungu bwifashe neza, igipimo cy’ibikorwa by’inganda zikora PVC zo mu gihugu cyabaye kinini, isoko ryoherezwa mu mahanga rya PVC ryarashyushye, kandi n’ibisabwa kuri disiki zo hanze biriyongera. Umubare werekana icyerekezo runaka cyiterambere, kandi imikorere rusange yisoko yarateye imbere ugereranije nigihe cyashize.
