I-MIT: I-polylactic-glycolic acid copolymer microparticles yenza isitofu sokugonya "ukuziphucula".
Izazinzulu kwi-Massachusetts Institute of Technology (MIT) zinika ingxelo kwijenali yamva nje ye-Science Advances ukuba zenza idosi enye yokugonya ukuzikhulisa. Emva kokuba isitofu sokugonya sitofwe emzimbeni womntu, sinokukhutshwa izihlandlo ezininzi ngaphandle kwesidingo sokudubula kwe-booster. Isitofu sokugonya esitsha kulindeleke ukuba sisetyenziswe ngokuchasene nezifo ukusuka kumasisi ukuya kwi-Covid-19. Kuxelwa ukuba olu gonyo lutsha lwenziwe ngamasuntswana e-poly(lactic-co-glycolic acid) (PLGA). I-PLGA yikhompawundi eyonakakayo yepolymer ephilayo, engeyotyhefu kwaye inokuhambelana kakuhle kwezinto eziphilayo. Ivunyiwe ukuba isetyenziswe kwii-Implants, sutures, izinto zokulungisa, njl -
Inkampani yeMichiza yaseYuneng: Imveliso yokuqala yemveliso yepolyethylene etshizwayo!
Kutshanje, iyunithi ye-LLDPE yeZiko lePolyolefin yeYuneng Chemical Company ivelise ngempumelelo i-DFDA-7042S, imveliso yepolyethylene etshizwayo.

Petronas I-1.65 yezigidi zeetoni ze-polyolefin malunga nokubuyela kwimarike yaseAsia!
Ngokweendaba zamva nje, iPengerang eJohor Bahru, eMalaysia, iphinde yaqalisa iyunithi yayo ye-350,000-ton/year linear low-density polyethylene (LLDPE) ngomhla we-4 kaJulayi, kodwa iyunithi inokuthatha ixeshana Ukuphumeza umsebenzi ozinzileyo. Ngaphandle koko, iteknoloji yayo ye-Spheripol i-450,000 yeetoni / ngonyaka i-polypropylene (PP) plant, i-400,000 yeetoni / ngonyaka i-high-density polyethylene (HDPE) iplanti kunye ne-Spherizone iteknoloji ye-450,000 yeetoni / ngonyaka we-polypropylene (PP) isityalo kulindeleke ukuba yande ukusuka kule nyanga ukuze iqalise kwakhona. Ngokutsho kovavanyo lwe-Argus, ixabiso le-LLDPE kuMzantsi-mpuma we-Asia ngaphandle kwerhafu ngoJulayi 1 yi-US $ 1360-1380 / itoni ye-CFR, kwaye ixabiso le-PP yocingo lomzobo kuMzantsi-mpuma we-Asia ngoJulayi 1 yi-US $ 1270-1300 / itoni ye-CFR ngaphandle kwerhafu. -
Imidiza itshintshela kwipakethe yeplastiki enokubola eIndiya.
Ukuvalwa kwe-India kwiiplastiki ezili-19 ezisetyenziswa kanye kuphela kuye kwabangela utshintsho kushishino lwecuba. Ngaphambi komhla woku-1 kuJulayi, abavelisi becuba baseIndiya babeyitshintshile ipakethe yabo yeplastiki yesiqhelo yangaphambili bayifaka kwiplastiki ebolisiweyo. Iziko leTobacco laseIndiya (TII) libanga ukuba amalungu alo aguqukile kwaye iiplastiki ezisetyenziswayo ezinokubola zifikelela kwimigangatho yamazwe ngamazwe, kwakunye nomgangatho weBIS osandul’ ukukhutshwa. Bakwabanga ukuba ukuthotywa kwe-biodegradation yeeplastiki ze-biodegradable iqala ngokudibana nomhlaba kwaye ngokwemvelo i-biodegraded kwi-compost ngaphandle kokugxininisa ukuqokelelwa kwenkunkuma eqinileyo kunye neenkqubo zokuphinda zisetyenziswe. -

Kwenzeke ugqabhuko-dubulo kwindawo yePVC yesigebenga sepetrochemical kuMbindi Mpuma!
Isigebenga sepetrochemical saseTurkey uPetkim ubhengeze ukuba ngorhatya lwe-19 kaJuni ngo-2022, kwenzeka ugqabhuko-dubulo kwisityalo sase-Aliaga. ingozi yenzeke kwi-reactor ye-PVC yomzi-mveliso, akukho mntu wonzakeleyo, umlilo wakhawuleza phantsi kolawulo, kodwa iyunithi ye-PVC ingaba i-offline okwethutyana ngenxa yengozi. Isiganeko sinokuba nempembelelo enkulu kwimarike yendawo yePVC yaseYurophu. Kuxelwa ukuba ngenxa yokuba ixabiso lePVC eChina liphantsi kakhulu kuneemveliso zasekhaya zaseTurkey, kwaye ixabiso lendawo yePVC eYurophu liphezulu kunelo laseTurkey, uninzi lweemveliso zePVC zePetkim zithunyelwa ngoku kwimarike yaseYurophu. -
I-BASF iphuhlisa iitreyi ze-oveni eziqatywe ngePLA !
Ngomhla wama-30 kuJuni, i-2022, i-BASF kunye nomvelisi wokupakishwa kokutya wase-Australia u-Confoil baye bahlangana ukuphuhlisa i-compostable eqinisekisiweyo, i-double-function-function-friendly paper tray yokutya yephepha-DualPakECO®. Ngaphakathi kwitreyi yephepha yagqunywe nge-BASF's ecovio® PS1606, i-high-performance general-purpose bioplastic ye-bioplastic eveliswe ngokurhweba yi-BASF. Yiplastiki ehlaziyekayo enokubola (i-70% yomxholo) edityaniswe neemveliso ze-ecoflex ze-BASF kunye ne-PLA, kwaye isetyenziselwa ngokukodwa ukuveliswa kweengubo zokupakisha ukutya kwamaphepha okanye amakhadibhodi. Zineempawu zothintelo ezilungileyo kumafutha, ulwelo kunye namavumba kwaye zinokonga ukukhutshwa kwerhasi yegreenhouse. -
Ukufaka iifiber zepolylactic acid kwiiyunifomu zesikolo.
I-Fengyuan Bio-Fiber isebenzisane neFujian Xintongxing ukufaka ifayibha ye-polylactic acid kumalaphu okunxiba esikolweni. Ukufunxa ukufuma kwayo okugqwesileyo kunye nomsebenzi wokubila kuphindwe ka-8 kunemicu yepolyester eqhelekileyo. I-PLA fiber ineepropathi ezingcono kakhulu zokulwa ne-antibacterial kunayo nayiphi na enye imicu. I-curling resilience ye-fiber ifikelela kwi-95%, eyona nto ingcono kakhulu kunayo nayiphi na enye i-chemical fiber. Ukongeza, ilaphu elenziwe ngefayibha ye-polylactic acid ilula eluswini kwaye inobungqina bokufuma, ishushu kwaye iyaphefumla, kwaye inokuthintela iibhaktheriya kunye namangolwane, kwaye inqande ilangatye kwaye ingatshi. Iiyunifomu zesikolo ezenziwe ngeli laphu zihambelana nokusingqongileyo, zikhuselekile kwaye zikhululekile. -
Isikhululo seenqwelomoya saseNanning: Cacisa izinto ezingaboliyo, nceda ufake ezonakeleyo
Isikhululo seenqwelo-moya saseNanning sikhuphe “i-Nanning Airport Plastic Ban and Restriction Management Regulations” ukukhuthaza ukuphunyezwa kolawulo longcoliseko lweplastiki ngaphakathi kwesikhululo seenqwelo-moya. Okwangoku, zonke iimveliso zeplastiki ezingonakali zitshintshelwe kwezinye iindawo ezinokonakala kwiivenkile ezinkulu, kwiivenkile zokutyela, kwiindawo zokuphumla abakhweli, iindawo zokupaka iimoto kunye nezinye iindawo kwisakhiwo se-terminal, kwaye iinqwelomoya zabakhweli basekhaya ziyekile ukubonelela ngezitro zeplastiki ezilahlwayo ezingonakaliyo, iintonga ezixhokonxayo, iingxowa zokupakisha, ukusebenzisa iimveliso ezinokonakala okanye ezinye iindlela. Qonda ngokubanzi "ukucocwa" kweemveliso zeplastiki ezingonakali, kwaye "nceda ungene" ukuze ufumane ezinye iindlela zokusingqongileyo. -
Yintoni iPP resin?
I-Polypropylene (PP) yi-thermoplastic eqinile, eqinile, kunye ne-crystalline. Yenziwe kwi-propene (okanye ipropylene) i-monomer. Le ntlaka yomgqa wehydrocarbon yeyona polima ikhaphukhaphu kuzo zonke iiplastiki zemveliso. I-PP iza njenge-homopolymer okanye njenge-copolymer kwaye inokunyuswa kakhulu kunye nezongezo. Ipolypropylene ekwabizwa ngokuba yi-polypropene, yipolymer ye-thermoplastic esetyenziswa kwiintlobo ngeentlobo zezicelo. Iveliswa nge-chain-growth polymerization ukusuka kwi-monomer propylene.I-Polypropylene yeyeqela le-polyolefins kwaye i-crystalline ngokuyinxenye kunye ne-non-polar. Iipropathi zayo zifana ne-polyethylene, kodwa inzima kancinci kwaye iyamelana nobushushu. Yimathiriyeli emhlophe, enoomatshini kwaye inokumelana nemichiza ephezulu.
