Isikhululo seenqwelo-moya saseNanning: Susa izinto ezingonakalisiyo, nceda ufake ezonakalisiyoyo
Isikhululo seenqwelo-moya saseNanning sikhuphe "iMimiselo yoLawulo lwePlastiki kunye neMiqathango yeSikhumulo seenqwelo-moya saseNanning" ukukhuthaza ukuphunyezwa kolawulo longcoliseko lweplastiki ngaphakathi kwisikhululo seenqwelo-moya. Okwangoku, zonke iimveliso zeplastiki ezingonakalisiyo zithathelwe indawo zezinye iindlela ezinokonakala kwiivenkile ezinkulu, kwiindawo zokutyela, kwiindawo zokuphumla zabakhweli, kwiindawo zokupaka iimoto nakwezinye iindawo kwisakhiwo sesiphelo, kwaye iinqwelomoya zasekhaya zabakhweli ziyekile ukubonelela ngeengca zeplastiki ezingasetyenziswayo, iintonga zokuxova, iingxowa zokupakisha, ukusebenzisa iimveliso okanye ezinye iindlela ezinokonakala. Qaphela "ukususwa" okupheleleyo kweemveliso zeplastiki ezingonakalisiyo, kwaye "nceda ungene" ukuze ufumane ezinye iindlela ezinobuhlobo nokusingqongileyo. -
Yintoni i-PP resin?
I-Polypropylene (PP) yi-thermoplastic eqinileyo, eqinileyo, nekristale. Yenziwe nge-propene (okanye i-propylene) monomer. Le resin ye-hydrocarbon ethe ngqo yeyona polymer ilula kakhulu kuzo zonke iiplastiki ezithengiswayo. I-PP iza njenge-homopolymer okanye njenge-copolymer kwaye inokwandiswa kakhulu ngezongezo. I-Polypropylene eyaziwa ngokuba yi-polypropene, yi-polymer ye-thermoplastic esetyenziswa kwiintlobo ngeentlobo zezicelo. Yenziwa nge-chain-growth polymerization evela kwi-monomer propylene. I-Polypropylene ikwiqela le-polyolefins kwaye i-crystalline kwaye ayi-polar. Iimpawu zayo zifana ne-polyethylene, kodwa inzima kancinci kwaye iyamelana nobushushu. Yinto emhlophe, eqinileyo kwaye inokumelana neekhemikhali eziphezulu. -

Uluhlu lwezinto ezisetyenzisiweyo lwaqhubeka luqokelelana, iPVC yalahlekelwa ziintlobo ngeentlobo zeelahleko.
Kutshanje, ixabiso le-PVC lasekhaya elingaphandle kwefektri lihlile kakhulu, inzuzo ye-PVC edibeneyo incinci, kwaye inzuzo yeetoni ezimbini zamashishini incitshisiwe kakhulu. Ukususela kwiveki entsha kaJulayi 8, iinkampani zasekhaya zifumene ii-odolo ezimbalwa zokuthumela ngaphandle, kwaye ezinye iinkampani azizange zibe nantengiselwano kwaye nemibuzo embalwa. I-FOB eqikelelweyo yeTianjin Port yi-US$900, ingeniso yokuthumela ngaphandle yi-US$6,670, kwaye iindleko zokuthutha ngaphandle kwefektri ukuya eTianjin Port zimalunga ne-6,680 yeedola zaseMelika. Uloyiko lwasekhaya kunye notshintsho olukhawulezileyo lwamaxabiso. Ukuze kuncitshiswe uxinzelelo lokuthengisa, kulindeleke ukuba ukuthunyelwa kwamanye amazwe kusaqhubeka, kwaye isantya sokuthenga siye sehla phesheya. -
Ukuthunyelwa kwamanye amazwe kwe-PVC eTshayina kusaqhubeka nokuba phezulu ngoMeyi.
Ngokwezibalo zamva nje zezerhafu, ngoMeyi ka-2022, ukuthunyelwa kwe-PVC pure powder kwilizwe lam bekungama-22,100 eetoni, ukunyuka kwe-5.8% ngonyaka; ngoMeyi ka-2022, ukuthunyelwa kwe-PVC pure powder kwilizwe lam bekungama-266,000 eetoni, ukunyuka kwe-23.0% ngonyaka. Ukususela ngoJanuwari ukuya kuMeyi ka-2022, ukungeniswa kwe-PVC pure powder ngaphakathi ekhaya bekungama-120,300 eetoni, ukwehla kwe-17.8% xa kuthelekiswa nexesha elifanayo kunyaka ophelileyo; ukuthunyelwa kwe-PVC pure powder ngaphakathi ekhaya bekungama-1.0189 eetoni ezigidi, ukunyuka kwe-4.8% xa kuthelekiswa nexesha elifanayo kunyaka ophelileyo. Ngokuhla kancinci kwemarike yePVC yasekhaya ukusuka kwinqanaba eliphezulu, iikowuteshini zokuthunyelwa kwePVC eTshayina ziyakhuphisana. -
Uhlalutyo lwedatha yokungenisa nokuthumela ngaphandle i-paste resin yaseTshayina ukususela ngoJanuwari ukuya kuMeyi
Ukususela ngoJanuwari ukuya kuMeyi ka-2022, ilizwe lam lingenise iitoni ezingama-31,700 ze-paste resin, ukwehla kwe-26.05% xa kuthelekiswa nexesha elifanayo kunyaka ophelileyo. Ukususela ngoJanuwari ukuya kuMeyi, iTshayina ithumele iitoni ezingama-36,700 ze-paste resin, ukunyuka kwe-58.91% xa kuthelekiswa nexesha elifanayo kunyaka ophelileyo. Uhlalutyo lukholelwa ukuba ubuninzi beemarike bukhokelele ekwehleni okuqhubekayo kwemarike, kwaye inzuzo yeendleko kurhwebo lwangaphandle iye yabonakala. Abavelisi be-paste resin nabo bafuna ngamandla ukuthunyelwa kwamanye amazwe ukuze banciphise unxibelelwano lokubonelela kunye nemfuno kwimarike yasekhaya. Umthamo wokuthunyelwa kwamanye amazwe wenyanga ufikelele kwincopho kwiminyaka yakutshanje. -
Ii-microneedles ezinemingxuma ze-PLA: ukufunyanwa ngokukhawuleza kwe-antibody ye-covid-19 ngaphandle kweesampuli zegazi
Abaphandi baseJapan baphuhlise indlela entsha esekelwe kwi-antibody yokufumanisa ngokukhawuleza nangokuthembekileyo i-coronavirus entsha ngaphandle kwesidingo seesampuli zegazi. Iziphumo zophando zipapashwe kutshanje kwingxelo yeJenali yeSayensi. Ukuchongwa okungafanelekanga kwabantu abosulelwe yi-covid-19 kuyithintele kakhulu impendulo yehlabathi kwi-COVID-19, eyanda ngenxa yesantya esiphezulu sosulelo olungenazimpawu (16% - 38%). Okwangoku, indlela ephambili yokuvavanya kukuqokelela iisampuli ngokusula impumlo nomqala. Nangona kunjalo, ukusetyenziswa kwale ndlela kuthintelwe lixesha layo elide lokufumanisa (iiyure ezi-4-6), iindleko eziphezulu kunye neemfuno zezixhobo zobungcali kunye nabasebenzi bezonyango, ngakumbi kumazwe anezixhobo ezinqongopheleyo. Emva kokuqinisekisa ukuba ulwelo oluphakathi lunokufaneleka kwi-antibody... -
