Ni ibihe biranga Polypropylene (PP)?
Zimwe mu ngingo z'ingenzi za polypropylene ni: 1. Ubudahangarwa mu bya chimique: Ishingiro n'aside byavanzwe ntibikunze gukorana na polypropylene, bituma iba amahitamo meza ku bikoresho birimo ibyo bintu by'amazi, nk'ibikoresho byo gusukura, ibikoresho by'ubutabazi bw'ibanze, n'ibindi. 2. Ubudahangarwa n'Ubukomere: Polypropylene ikora neza ku buryo ihinduka mu buryo runaka bwo guhindagurika (nk'ibindi bikoresho byose), ariko izahura n'ubudahangarwa bwa pulasitiki mu ntangiriro z'uburyo bwo guhindagurika, bityo muri rusange ifatwa nk'ikintu "kikomeye". Ubukomere ni ijambo ry'ubuhanga risobanurwa nk'ubushobozi bw'ikintu bwo guhindagurika (nk'uburyo bwa pulasitiki, ntabwo ari uburyo bwo guhindagurika) kitavunitse. 3. Ubudahangarwa mu Kunanirwa: Polypropylene igumana imiterere yayo nyuma yo guhindagurika cyane, guhindagurika, cyangwa guhindagurika. Iyi miterere ni... -
Amakuru y’ubutaka arakumirwa nabi, kandi PVC iragaragara.
Ku wa mbere, amakuru y’ubutaka yakomeje kugenda buhoro, byagize ingaruka mbi cyane ku byitezwe ku busabe bw’ibiciro. Mu mpera z’uyu mwaka, amasezerano nyamukuru ya PVC yagabanutseho ibirenze 2%. Mu cyumweru gishize, amakuru ya CPI ya Amerika muri Nyakanga yari make ugereranyije n’uko byari byitezwe, ibyo bikaba byongereye ubushake bw’abashoramari bwo kubona inyungu. Muri icyo gihe, ubusabe bwa zahabu, ifeza icyenda n’ibihe icumi by’ibiciro byari byitezwe ko buzamuka, ibyo bikaba byaratanze inkunga ku biciro. Ariko, isoko rifite gushidikanya ku kuntu ubusabe buhagaze mu kuzamuka kw’isaha. Ubwiyongere bwatewe no kuzamuka kw’isaha y’imbere mu gihugu mu gihe giciriritse n’igihe kirekire bushobora kutabasha gukuraho ukwiyongera kwatewe no kuzamuka kw’isaha y’ibiciro n’igabanuka ry’isaha y’ibiciro byatewe n’isaha y’ibiciro by ... -
Sinopec, PetroChina n'abandi basabye ku bushake bwabo kuva ku rutonde rw'imigabane muri Amerika!
Nyuma yo gukurwa ku rutonde rwa CNOOC mu Isoko ry'Imari rya New York, amakuru agezweho ni uko ku gicamunsi cyo ku ya 12 Kanama, PetroChina na Sinopec batangaje amatangazo agaragaza ko bateganya gukuraho imigabane y'Abanyamerika mu Isoko ry'Imari rya New York. Byongeye kandi, Sinopec Shanghai Petrochemical, Ubwishingizi bw'Ubuzima bw'Abashinwa, na Aluminium Corporation yo mu Bushinwa na byo byatangaje amatangazo agaragaza ko biteguye gukuraho imigabane y'Abanyamerika mu Isoko ry'Imari rya New York. Dukurikije amatangazo y'ibigo bireba, aya masosiyete yubahiriza amategeko agenga isoko ry'imari n'imigabane rya Amerika kuva yashyirwa ahagaragara muri Leta Zunze Ubumwe za Amerika, kandi amahitamo yo gukuraho ku rutonde yakozwe bitewe n'ibyo bireba mu bucuruzi bwabo. -
Umupira wa mbere wa PHA ku isi watangijwe!
Ku ya 23 Gicurasi, ikigo cy’Abanyamerika gishinzwe ubuvuzi bw’amenyo Plackers®, cyashyize ahagaragara EcoChoice Compostable Floss, urudodo rw’amenyo ruhoraho rushobora kwangirika 100% mu rugo rushobora kwangirika. EcoChoice Compostable Floss ikomoka kuri Danimer Scientific's PHA, biopolymer ikomoka ku mavuta ya canola, urudodo rw’ubudodo karemano n’ibishishwa by’amasaka ya kokonati. Uru rudodo rushya rushobora kwangirika rwuzuza urwego rw’ubuvuzi bw’amenyo rurambye rwa EcoChoice. Ntabwo rutanga gusa ko rukenewe, ahubwo runagabanya amahirwe yo kwangirika kwa pulasitiki mu nyanja no mu myanda. -
Isesengura ku iterambere ry'inganda za PVC muri Amerika ya Ruguru.
Amerika ya Ruguru ni yo karere ka kabiri ku isi gakoreramo PVC nyinshi. Mu 2020, umusaruro wa PVC muri Amerika ya Ruguru uzaba toni miliyoni 7.16, bingana na 16% by'umusaruro wa PVC ku isi. Mu gihe kizaza, umusaruro wa PVC muri Amerika ya Ruguru uzakomeza kuzamuka. Amerika ya Ruguru ni yo yohereza PVC mu mahanga menshi ku isi, ingana na 33% by'ubucuruzi bwa PVC bwoherezwa mu mahanga ku isi. Bitewe n'uko Amerika ya Ruguru iboneka bihagije, ingano y'ibitumizwa mu mahanga ntabwo iziyongera cyane mu gihe kizaza. Mu 2020, ikoreshwa rya PVC muri Amerika ya Ruguru ni toni miliyoni 5.11, hafi 82% muri zo ziherereye muri Leta Zunze Ubumwe za Amerika. Ikoreshwa rya PVC muri Amerika ya Ruguru ahanini rituruka ku iterambere ry'isoko ry'ubwubatsi. -
HDPE ikoreshwa mu ki?
HDPE ikoreshwa mu bicuruzwa no mu bipfunyika nko mu macupa y'amata, amacupa y'isabune, mu tubati twa margarine, mu bikoresho by'imyanda n'imiyoboro y'amazi. Mu tubati dufite uburebure butandukanye, HDPE ikoreshwa nk'isimbura utubati twa morti two mu ikarito kubera impamvu ebyiri z'ingenzi. Iya mbere, ni nziza cyane kuruta utubati twa mortito kuko iyo igikonjo cyangiritse kikagwa mu muyoboro wa HDPE, umuyoboro ntuzameneka. Impamvu ya kabiri ni uko zishobora kongera gukoreshwa bituma abashushanya bakora uduce twinshi twa mortito. Abahanga mu by'imiti babuza ikoreshwa rya PVC mu tubati twa mortito kuko ikunda kumenagurika, yohereza ibice bya pulasitiki ku bareba bashobora kuba bareba, kandi ntizagaragara muri X-rays. -
Ikarita y'icyatsi kibisi ya PLA iba igisubizo kirambye gikunzwe cyane ku nganda z'imari.
Hakenewe pulasitike nyinshi kugira ngo hakorwe amakarita ya banki buri mwaka, kandi kubera impungenge z’ibidukikije zikomeje kwiyongera, Thales, umuyobozi mu by’umutekano mu ikoranabuhanga rigezweho, yateguye igisubizo. Urugero, ikarita ikozwe muri aside polylactic 85% (PLA), ikomoka ku bigori; ubundi buryo bushya ni ugukoresha inyabutabire zikomoka ku bikorwa byo gusukura inkombe binyuze mu bufatanye n’itsinda ry’ibidukikije rya Parley for the Oceans. Imyanda ya pulasitiki yakusanyijwe - "Ocean Plastic®" nk'ibikoresho fatizo bishya byo gukora amakarita; hari kandi amahitamo ku makarita ya PVC ashobora kongera gukoreshwa akozwe mu myanda ya pulasitiki ikomoka mu nganda zipakira no gucapa kugira ngo agabanye ikoreshwa rya pulasitiki nshya. -
Isesengura rigufi ry'amakuru y'ibicuruzwa byinjizwa n'ibicuruzwa byoherezwa mu mahanga bya resin ya pvc mu Bushinwa kuva muri Mutarama kugeza muri Kamena.
Kuva muri Mutarama kugeza muri Kamena 2022, igihugu cyanjye cyatumije toni 37.600 za paste resin, kugabanukaho 23% ugereranije n’igihe nk’icyo umwaka ushize, kandi cyohereje toni 46.800 za paste resin, kuzamukaho 53.16% ugereranije n’igihe nk’icyo umwaka ushize. Mu gice cya mbere cy’umwaka, uretse ibigo byigenga byafunzwe kugira ngo bibungabungwe, umutwaro w’uruganda rwa paste resin rwo mu gihugu wagumye ku rwego rwo hejuru, ibicuruzwa byari bihagije, kandi isoko ryakomeje kugabanuka.

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 mvaruganda bwo mu 19277.1 bwemeje ko mu gihe cyo gukora ifumbire mvaruganda, 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. -

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).
