Musi wa1 Nyamavhuvhu, 2022, odha yePVC resin SG5 yakaiswa naLeon, maneja wekutengesa weChemdo, yakatakurwa nengarava huru panguva yakatarwa ndokusimuka kubva kuTianjin Port, China, ichienda kuGuayaquil, Ecuador. Rwendo rwacho rwuri KEY OHANA HKG131, nguva inofungidzirwa yekusvika i1 Gunyana. Tinovimba kuti zvese zvichafamba zvakanaka mukufambisa uye vatengi vachawana zvinhu nekukurumidza. -
Imba yekuratidzwa yaChemdo inotanga kuvakwa.
Mangwanani emusi wa4 Nyamavhuvhu, 2022, Chemdo yakatanga kushongedza imba yekuratidzira yekambani. Chiratidziro ichi chakagadzirwa nematanda akasimba kuratidza mhando dzakasiyana dzePVC, PP, PE, nezvimwewo. Chinonyanya kuita basa rekuratidza nekuratidza zvinhu, uye chinogonawo kuita basa rekuzivisa nekunyora, uye chinoshandiswa kutepfenyura mhenyu, kutora mifananidzo uye kutsanangura mudhipatimendi rezvenhau. Ndiri kutarisira kupedzisa nekukurumidza uye kukuunzirai zvakawanda zvekugovera. -
Ungaziva sei kana purasitiki iri polypropylene?
Imwe yenzira dziri nyore dzekuedza murazvo ndeyekucheka sampuro kubva mupurasitiki woibatidza mukabati remoto. Ruvara rwemurazvo, hwema uye hunhu hwekutsva zvinogona kuratidza rudzi rwepurasitiki: 1. Polyethylene (PE) - Madonhwe, anonhuwirira sewakisi yekenduru; 2. Polypropylene (PP) - Madonhwe, anonhuwirira mafuta einjini akasviba uye madonhwe ewakisi yekenduru; 3. Polymethylmethacrylate (PMMA, "Perspex") - Mabhubhu, maburi, hwema hunotapira; 4. Polyamide kana "Nylon" (PA) - Murazvo une hunyoro, hwema hwemarigolds; 5. Acrylonitrilebutadienestyrene (ABS) - Murazvo usina kujeka, une hunyoro, hwema hwemarigolds; 6. Polyethylene furo (PE) - Madonhwe, hwema hwemarigolds -
Mars M Beans yatanga kurongedza mapepa ePLA composite anogona kuora muChina.
Muna 2022, Mars yakatanga chokoreti yekutanga yeM&M yakaputirwa mupepa rinosanganiswa rinoora muChina. Yakagadzirwa nezvinhu zvinoora zvakaita sepepa nePLA, zvichitsiva kurongedza kwepurasitiki yakapfava yekare. Kurongedza kwacho kwapfuura GB/T. Nzira yekuongorora ya19277.1 yakaratidza kuti pasi pemamiriro ekugadzira manyowa mumaindasitiri, inogona kuora neanopfuura 90% mumwedzi mitanhatu, uye ichava mvura isina chepfu, carbon dioxide nezvimwe zvigadzirwa mushure mekuora. -

Chii chinonzi Polypropylene (PP)?
Polypropylene (PP) ipurasitiki yakasimba, yakasimba, uye ine crystalline. Yakagadzirwa nepropene (kana propylene) monomer. Iyi linear hydrocarbon resin ndiyo polymer yakareruka kupfuura mamwe mapurasitiki ese emhando yepamusoro. PP inouya sehomopolymer kana secopolymer uye inogona kuwedzerwa zvakanyanya. Inoshandiswa mumapakeji, mumotokari, muzvigadzirwa zvevatengi, mukurapa, mumafirimu esimbi, nezvimwewo. PP yave chinhu chinosarudzwa, kunyanya kana uchitsvaga polymer ine simba guru (semuenzaniso, vs Polyamide) mukushandisa kweinjiniya kana kungotsvaga mukana wekushandisa mumabhodhoro ekugadzira (vs. PET). -
Chii chinonzi Polyethylene (PE)?
Polyethylene (PE), inozivikanwawo se polythene kana polyethene, ndeimwe yemapurasitiki anonyanya kushandiswa pasi rose. Polyethylene inowanzova nechimiro chakatsetseka uye inozivikanwa semapolymer ekuwedzera. Kushandiswa kukuru kwemapolymer aya ekugadzira kuri mupakeji. Polyethelyne inowanzoshandiswa kugadzira mabhegi epurasitiki, mabhodhoro, mafirimu epurasitiki, midziyo, uye geomembranes. Zvinogona kucherechedzwa kuti matani anopfuura mamiriyoni zana epolyethene anogadzirwa gore rega rega nekuda kwezvinangwa zvebhizinesi nemaindasitiri. -
Ongororo yekushanda kwemusika wekutengesa zvinhu zvePVC munyika yangu muhafu yekutanga ya2022.
Muhafu yekutanga ya2022, musika wekutengesa kunze kwePVC wakawedzera gore negore. Muchikamu chekutanga, chakanganiswa nekushomeka kwehupfumi hwenyika pamwe nedenda iri, makambani mazhinji ekutengesa kunze kwenyika akaratidza kuti kudiwa kwemadisiki ekunze kwakadzikira zvishoma. Zvisinei, kubva pakutanga kwaChivabvu, nekuvandudzika kwemamiriro edenda uye matanho akateedzana akaunzwa nehurumende yeChina kukurudzira kudzoreredzwa kwehupfumi, mwero wekushanda kwemabhizinesi ekugadzira PVC emuno wave wakakwira, musika wekutengesa kunze kwePVC wawedzera, uye kudiwa kwemadisiki ekunze kwawedzera.

MIT: Polylactic-glycolic acid copolymer microparticles inodzivirira "kuzvivandudza".
Masayendisiti eMassachusetts Institute of Technology (MIT) anoshuma mumagazini yeScience Advances munguva pfupi yapfuura kuti vari kugadzira mushonga wekudzivirira muviri unozviwedzera simba rimwe chete. Mushure mekunge mushonga wacho waiswa mumuviri wemunhu, unogona kuburitswa kakawanda pasina chikonzero chekuisa mushonga wekuwedzera simba. Mushonga mutsva uyu unotarisirwa kushandiswa kurwisa zvirwere zvinotangira pagwirikwiti kusvika kuCovid-19. Zvinonzi mushonga mutsva uyu wakagadzirwa nezvidimbu zvepoly(lactic-co-glycolic acid) (PLGA). PLGA chinhu chinoshanda chepolymer organic, chisina chepfu uye chinoshanda zvakanaka. Chakatenderwa kushandiswa muImplants, sutures, zvinhu zvekugadzirisa, nezvimwewo.
