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. -
PVC ya Chemdo resin SG5 ibicuruzwa byoherejwe nubwikorezi bwinshi ku ya 1 Kanama.
Ku ya 1 Kanama 2022, itegeko rya PVC risin SG5 ryashyizweho na Leon, umuyobozi ushinzwe kugurisha Chemdo, ryajyanywe mu bwato bwinshi mu gihe cyagenwe maze rihaguruka ku cyambu cya Tianjin mu Bushinwa, ryerekeza i Guayaquil, muri uquateur. Urwo rugendo ni URUKINGO OHANA HKG131, igihe cyagenwe cyo kuhagera ni 1 Nzeri. Turizera ko ibintu byose bigenda neza muri transit kandi abakiriya babona ibicuruzwa vuba bishoboka. -
Icyumba cy'imurikagurisha cya Chemdo gitangira kubakwa.
Mu gitondo cyo ku ya 4 Kanama 2022, Chemdo yatangiye gushushanya icyumba cy'imurikabikorwa. Imurikagurisha rikozwe mu biti bikomeye kugira ngo ryerekane ibirango bitandukanye bya PVC, PP, PE, n'ibindi. Bifite uruhare runini mu kwerekana no kwerekana ibicuruzwa, kandi birashobora no kugira uruhare mu kumenyekanisha no kwerekana, kandi bikoreshwa mu gutangaza imbonankubone, kurasa no kwisobanura mu ishami ryitangazamakuru ryigenga. Dutegereje kuzarangiza vuba bishoboka no kukuzanira byinshi. ? -
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%. Ibicuruzwa byoherezwa mu mahanga byakomeje kugumana urwego rwo hejuru, byagabanije gutanga isoko ryinshi ku isoko ry’imbere ku rugero runaka. -
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. -
Niki PVC ikoreshwa?
Ubukungu, butandukanye bwa polyvinyl chloride (PVC, cyangwa vinyl) bukoreshwa muburyo butandukanye mu nyubako n’ubwubatsi, ubuvuzi, ibikoresho bya elegitoroniki, ibinyabiziga n’izindi nzego, mu bicuruzwa biva mu miyoboro no ku mpande, imifuka y’amaraso no kuvoma, kugeza insinga n’insinga, ibikoresho bya sisitemu y’ikirahure n'ibindi. ? -
Inama yo mu gitondo ya Chemdo ku ya 26 Nyakanga.
Mu gitondo cyo ku ya 26 Nyakanga, Chemdo yakoze inama rusange. Mu ikubitiro, umuyobozi mukuru yagaragaje igitekerezo cye ku bijyanye n’ubukungu bwifashe muri iki gihe: ubukungu bw’isi bwifashe nabi, inganda z’ubucuruzi zose z’amahanga zihebye, icyifuzo kiragabanuka, kandi n’ubwikorezi bwo mu nyanja buragabanuka. Kandi wibutse abakozi ko mu mpera za Nyakanga, hari ibibazo byihariye bigomba gukemurwa, bishobora gutegurwa vuba bishoboka. Kandi yagennye insanganyamatsiko ya videwo nshya yiki cyumweru: Ihungabana rikomeye mubucuruzi bwamahanga. Hanyuma yatumiye bagenzi be benshi ngo basangire amakuru agezweho, arangije asaba ishami ryimari ninyandiko kubika neza inyandiko. ?
