Ikhadi eliluhlaza le-PLA liba sisisombululo esithandwayo esizinzileyo kwishishini lezemali.
Iplastiki eninzi kakhulu iyadingeka ukwenza amakhadi ebhanki minyaka yonke, kunye neenkxalabo zokusingqongileyo ezikhulayo, uThales, inkokeli yokhuseleko oluphezulu, uye wavelisa isisombululo. Ngokomzekelo, ikhadi elenziwe nge-85% ye-polylactic acid (PLA), ephuma kwingqolowa; enye indlela yokuqalisa entsha kukusebenzisa izicubu ezivela kwimisebenzi yokucoca unxweme ngentsebenziswano neqela lokusingqongileyo iParley for the Oceans. Inkunkuma yeplastiki eqokelelweyo – “i-Ocean Plastic®” njengesixhobo esivelisa izinto ezintsha zokwenziwa kwamakhadi; kukwakho nokhetho lwamakhadi ePVC aphinda asetyenziswe enziwe ngokupheleleyo kwinkunkuma yeplastiki ukusuka kushishino lokupakisha nokushicilela ukunciphisa ukusetyenziswa kweplastiki entsha. -
Uhlalutyo olufutshane lwe-China yokuncamathelisa i-pvc resin yokungenisa kunye nedatha yokuthumela ngaphandle ukusuka ngoJanuwari ukuya kuJuni.
Ukusukela ngoJanuwari ukuya kuJuni ka-2022, ilizwe lam lingenise iitoni ezingama-37,600 zentlama yokuncamathelisa, ukuhla nge-23% xa kuthelekiswa nexesha elifanayo kulo nyaka uphelileyo, kwaye yathumela ngaphandle iitoni ezingama-46,800 zentlaka yokuncamathelisa, ukwanda kwe-53.16% xa kuthelekiswa nexesha elifanayo kunyaka ophelileyo. Kwisiqingatha sokuqala sonyaka, ngaphandle kwamashishini avalayo ukuze alungiswe, umthwalo wokusebenza weplanti yentlama yasekhaya uhleli ukwinqanaba eliphezulu, unikezelo lwempahla lwanele, kwaye imakethi iqhubekile nokuhla. Abavelisi bafuna ii-odolo zokuthumela ngaphandle ukuze banciphise ungquzulwano lwemalike yasekhaya, kwaye umthamo wokuthumela ngaphandle unyuke kakhulu. -
I-Chemdo's PVC resin SG5 iiodolo ezithunyelwe ngothutho ngobuninzi nge-1 ka-Agasti.
Ngomhla woku-1 ku-Agasti, i-2022, i-PVC ye-resin SG5 i-odolo ebekwe ngu-Leon, umphathi wentengiso we-Chemdo, yahanjiswa ngenqanawa enkulu ngexesha elimisiweyo kwaye isuka e-Tianjin Port, e-China, isiya e-Guayaquil, e-Ecuador. Uhambo luyi-KEY OHANA HKG131, ixesha eliqikelelweyo lokufika nguSeptemba 1. Sithemba ukuba yonke into ihamba kakuhle ekuhambeni kwaye abathengi bafumana iimpahla ngokukhawuleza. -
Igumbi lomboniso likaChemdo liqalisa ukwakhiwa.
Ngentsasa ye-4 ka-Agasti 2022, uChemdo waqala ukuhombisa igumbi lomboniso lenkampani. Umboniso wenziwe ngomthi oqinileyo ukubonisa iimpawu ezahlukeneyo zePVC, i-PP, i-PE, njl. Ngokukodwa idlala indima yokubonisa kunye nokubonisa iimpahla, kwaye inokudlala indima yopapasho kunye nokunikezelwa, kwaye isetyenziselwa ukusasazwa ngokuphila, ukudubula kunye nenkcazo kwisebe le-self-media. Ndijonge phambili ekuyigqibeni ngokukhawuleza kwaye sikuzisele ukwabelana ngakumbi. -
Unokwazi njani ukuba iplastiki yipolypropylene?
Enye yeendlela ezilula zokwenza uvavanyo lwedangatye kukusika isampulu yeplastiki uyitshise ekhabhathini yomsi. Umbala wedangatye, ivumba kunye neempawu zokutshisa unokunika isibonakaliso sohlobo lweplastiki: 1. Polyethylene (PE) - Ithontsiza, ivumba njengekhandlela; 2.Polypropylene (PP) - Ivuza, ivumba kakhulu ioli ye-injini engcolileyo kunye ne-undertones ye-candlewax 3. Polyethylene (PE) - I-Drips, ivumba njenge-candlewax; i-2.Polypropylene (PP) - I-Drips, ivumba kakhulu ioli ye-injini engcolileyo kunye ne-undertones ye-candlewax 3. Polyethylene (PE) - I-Drips, ivumba njenge-candlewax; 4. I-Polyamide okanye “Nayiloni” (PA) – Idangatye elithambileyo, ivumba leemarigolds; 5. Acrylonitrilebutadienestyrene (ABS) – Ayicacanga, idangatye elithambileyo, ivumba le-marigolds; -
Iimbotyi ze-Mars M ziphehlelela ukupakishwa kwamaphepha e-PLA anokuboliseka e-China.
Ngo-2022, uMars waphehlelela itshokolethi yokuqala yeM&M epakishwe kwiphepha elidityanisiweyo elonakeleyo eTshayina. Yenziwe ngezinto ezinokonakala ezifana nephepha kunye ne-PLA, ithatha indawo yokupakishwa kweplastiki ethambileyo yexesha elidlulileyo. Ukupakishwa kudlulile i-GB / T Indlela yokuzimisela ye-19277.1 iqinisekisile ukuba phantsi kweemeko zokudibanisa i-industrial, inokunciphisa ngaphezu kwe-90% kwiinyanga ze-6, kwaye iya kuba yi-non-biologically toxic, i-carbon dioxide kunye nezinye iimveliso emva kokuthotywa. -
Ukuthunyelwa ngaphandle kwePVC yaseTshayina kuhlala kuphezulu kwisiqingatha sokuqala sonyaka.
Ngokwezibalo zamasiko zamva nje, ngoJuni 2022, umthamo welizwe lam lokungenisa iPVC umgubo ococekileyo wawuyi-29,900 yeetoni, ukwanda kwe-35.47% ukusuka kwinyanga edlulileyo kunye nokunyuka konyaka-ngonyaka we-23.21%; ngoJuni 2022, i-PVC yelizwe lam i-powder ecocekileyo yokuthunyelwa kwe-powder yayiyi-223,500 yeetoni, Ukuncipha kwenyanga-ngenyanga kwakuyi-16%, kwaye ukunyuka konyaka-nyaka kwaba yi-72.50%. Umthamo wokuthunyelwa kwempahla kumazwe angaphandle uqhubekile nokugcina umgangatho ophezulu, othomalalise unikezelo oluninzi oluthe kratya kurhwebo lwangaphakathi ukuya kumlinganiselo othile. -
Yintoni iPolypropylene (PP) ?
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. Ifumana isicelo kwi-packaging, i-automotive, umthengi olungileyo, unyango, iifilimu eziphosiweyo, njl njl. I-PP iye yaba yinto ekhethiweyo, ngakumbi xa ukhangele i-polymer enamandla kakhulu (umzekelo, vs Polyamide) kwizicelo zobunjineli okanye ukukhangela nje inzuzo yeendleko ekuvutheleni iibhotile zokubumba (vs. PET). -
Yintoni iPolyethylene (PE) ?
I-Polyethylene (PE) , ekwabizwa ngokuba yi-polythene okanye i-polyethene, yenye yeeplastiki ezisetyenziswa ngokuqhelekileyo kwihlabathi. Iipolyethylenes zihlala zinesakhiwo somgca kwaye zaziwa njengeepolima ezongezelelweyo. Olona setyenziso luphambili lwezi polima zokwenziwa kukupakishwa. I-Polyethelyne isoloko isetyenziselwa ukwenza iingxowa zeplastiki, iibhotile, iifilim zeplastiki, izikhongozeli kunye nee-geomembranes. Kunokuqatshelwa ukuba ngaphezu kwe-100 lezigidi zeetoni ze-polyethene ziveliswa ngonyaka ngeenjongo zorhwebo kunye nezoshishino. -
Uhlalutyo lokusebenza kwemarike yelizwe lam yePVC yokuthumela ngaphandle kwisiqingatha sokuqala sika-2022.
Kwisiqingatha sokuqala sika-2022, imakethi yePVC yokuthumela ngaphandle yonyuka unyaka nonyaka. Kwikota yokuqala, echatshazelwa kukudodobala koqoqosho lwehlabathi kunye nobhubhane, iinkampani ezininzi zasekhaya ezithumela ngaphandle zibonise ukuba imfuno yeediski zangaphandle yancitshiswa. Nangona kunjalo, ukususela ekuqaleni kukaMeyi, ngokuphuculwa kwemeko yobhubhane kunye noluhlu lwamanyathelo aqaliswe ngurhulumente waseTshayina ukukhuthaza ukubuyiswa koqoqosho, izinga lokusebenza kwamashishini okuvelisa i-PVC yasekhaya iye yanda kakhulu, imarike yokuthumela ngaphandle kwe-PVC iye yafudumala, kwaye imfuno yeediski zangaphandle iye yanda. Inani libonisa indlela ethile yokukhula, kwaye ukusebenza ngokubanzi kweemarike kuphuculwe xa kuthelekiswa nexesha elidlulileyo. -
Isetyenziselwa ntoni iPVC?
I-Economical, i-polyvinyl chloride esebenzayo (i-PVC, okanye i-vinyl) isetyenziswe kwiintlobo ezahlukeneyo zezicelo kwisakhiwo kunye nokwakhiwa, ukunakekelwa kwezempilo, i-electronics, imoto kunye namanye amacandelo, kwiimveliso ezivela kwimibhobho kunye ne-siding, izikhwama zegazi kunye ne-tubing, ukuya kwi-wire kunye ne-cable insulation, i-windshield system components kunye nokunye. -
Intlanganiso yasekuseni yaseChemdo ngoJulayi 26.
Ngentsasa yomhla wama-26 kaJulayi, uChemdo wabamba intlanganiso edibeneyo. Ekuqaleni, umphathi-jikelele wavakalisa iimbono zakhe malunga nemeko yezoqoqosho yangoku: uqoqosho lwehlabathi luphantsi, yonke imboni yezorhwebo yangaphandle idandathekile, imfuno iyancipha, kwaye izinga lokuthutha elwandle liyancipha. Yaye bakhumbuze abasebenzi ukuba ekupheleni kukaJulayi, kukho imiba ethile yobuqu ekufuneka isingathwe, enokulungiswa ngokukhawuleza kangangoko kunokwenzeka. Kwaye uzimisele umxholo wevidiyo entsha yeendaba zale veki: Uxinzelelo olukhulu kurhwebo lwangaphandle. Emva koko wamema oogxa bakhe abaliqela ukuba babelane ngeendaba zamva nje, kwaye ekugqibeleni wabongoza isebe lezemali kunye namaxwebhu ukuba agcine amaxwebhu kakuhle.
