Isetyenziselwa ntoni i-HDPE?
I-HDPE isetyenziswa kwiimveliso nakwiipakethe ezifana neejagi zobisi, iibhotile zesepha, iibhafu zemargarine, izikhongozeli zenkunkuma kunye neepayipi zamanzi. Kwiityhubhu ezinobude obahlukeneyo, i-HDPE isetyenziswa endaweni yeetyhubhu zekhadibhodi zemortar ezibonelelweyo ngezizathu ezibini eziphambili. Okokuqala, ikhuselekile kakhulu kuneetyhubhu zekhadibhodi ezibonelelweyo kuba ukuba iqokobhe lingasebenzi kakuhle kwaye liqhume ngaphakathi kwityhubhu ye-HDPE, ityhubhu ayizukuqhekeka. Isizathu sesibini kukuba zingasetyenziswa kwakhona zivumela abayili ukuba benze iirakhi ezininzi zemortar. Iingcali zePyrotechnical azikukhuthazi ukusetyenziswa kweetyhubhu zePVC kwiityhubhu zemortar kuba idla ngokuqhekeka, ithumele iziqwenga zeplastiki kubabukeli abanokubakho, kwaye ayizukubonakala kwi-X-ray. -
Ikhadi eliluhlaza le-PLA liba sisisombululo esidumileyo esizinzileyo kushishino lwezemali.
Kufuneka iplastiki eninzi kakhulu ukwenza amakhadi ebhanki minyaka le, kwaye ngenxa yokwanda kweengxaki zokusingqongileyo, uThales, okhokela kukhuseleko lobuchwephesha obuphezulu, uphuhlise isisombululo. Umzekelo, ikhadi elenziwe nge-85% polylactic acid (PLA), elivela kumbona; enye indlela entsha kukusebenzisa izicwili ezivela kwimisebenzi yokucoca unxweme ngokubambisana neqela lendalo iParley for the Oceans. Inkunkuma yeplastiki eqokelelweyo – “Ocean Plastic®” njengesixhobo esitsha sokwenza amakhadi; kukwakho nokukhetha amakhadi ePVC aphinda asetyenziswe enziwe ngokupheleleyo ngeplastiki elahliweyo evela kushishino lokupakisha nokushicilela ukunciphisa ukusetyenziswa kweplastiki entsha. -
Uhlalutyo olufutshane lwedatha yokungenisa nokuthumela ngaphandle i-resin ye-pvc ye-paste yaseTshayina ukususela ngoJanuwari ukuya kuJuni.
Ukususela ngoJanuwari ukuya kuJuni 2022, ilizwe lam lingenise iitoni ezingama-37,600 ze-paste resin, ukwehla kwe-23% xa kuthelekiswa nexesha elifanayo kunyaka ophelileyo, kwaye lithumele iitoni ezingama-46,800 ze-paste resin, ukonyuka kwe-53.16% xa kuthelekiswa nexesha elifanayo kunyaka ophelileyo. Kwisiqingatha sokuqala sonyaka, ngaphandle kwamashishini ngamanye avale ngenxa yokugcinwa, umthwalo wokusebenza wesityalo se-paste resin sasekhaya wahlala kwinqanaba eliphezulu, ukuhanjiswa kweempahla kwakwanele, kwaye imakethi yaqhubeka nokuhla. Abavelisi bafuna ngenkuthalo ii-odolo zokuthumela ngaphandle ukuze banciphise iingxabano zemarike yasekhaya, kwaye umthamo wokuthumela ngaphandle oqokelelweyo wanda kakhulu. -
Iiodolo zeChemdo ze-PVC resin SG5 zithunyelwe ngumthwali wezinto ezinkulu nge-1 ka-Agasti.
Ngomhla woku-1 ku-Agasti 2022, i-odolo ye-PVC resin SG5 eyabekwa nguLeon, umphathi wentengiso weChemdo, yathuthwa ngenqanawa enkulu ngexesha elimiselweyo yaza yanduluka eTianjin Port, eTshayina, yaya eGuayaquil, e-Ecuador. Uhambo luyi-KEY OHANA HKG131, ixesha eliqikelelweyo lokufika nguSeptemba 1. Siyathemba ukuba yonke into iza kuhamba kakuhle kwezothutho kwaye abathengi baza kufumana iimpahla ngokukhawuleza. -
Igumbi lemiboniso likaChemdo liqala ukwakhiwa.
Ngentsasa ye-4 ka-Agasti 2022, iChemdo yaqala ukuhombisa igumbi lemiboniso lenkampani. Umboniso wenziwe ngomthi oqinileyo ukubonisa iimpawu ezahlukeneyo zePVC, PP, PE, njl. Ngokuyintloko udlala indima yokubonisa nokubonisa iimpahla, kwaye unokudlala indima yokwazisa nokubonisa, kwaye usetyenziselwa ukusasazwa bukhoma, ukudubula kunye nengcaciso kwicandelo leendaba ezizimeleyo. Ndilangazelela ukuyigqiba ngokukhawuleza kwaye ndikuzisele ukwabelana okungakumbi. -
Ungazi njani ukuba iplastiki yipolypropylene?
Enye yezona ndlela zilula zokwenza uvavanyo lwelangatye kukusika isampuli kwiplastiki uze uyitshise kwikhabhathi yomlilo. Umbala welangatye, ivumba kunye neempawu zokutsha zinokubonisa uhlobo lweplastiki: 1. I-Polyethylene (PE) – Iidrips, zinuka njenge-candlewax; 2. I-Polypropylene (PP) – Iidrips, zinuka kakhulu ioyile yenjini engcolileyo kunye ne-candlewax engaphantsi; 3. I-Polymethylmethacrylate (PMMA, “Perspex”) – Amaqamza, ii-crackles, ivumba elimnandi elimnandi; 4. I-Polyamide okanye “i-Nylon” (PA) – Ilangatye elithambileyo, ivumba le-marigolds; 5. I-Acrylonitrilebutadienestyrene (ABS) – Ilangatye elingacacanga, elithambileyo, ivumba le-marigolds; 6. I-Polyethylene foam (PE) – Iidrips, ivumba le-candlewax -
I-Mars M Beans iqalise ukupakisha iphepha le-PLA elidityanisiweyo elibolayo eTshayina.
Ngowama-2022, iMars yaqalisa itshokholethi yokuqala ye-M&M epakishwe kwiphepha elidityanisiweyo elibolayo eTshayina. Yenziwe ngezinto ezibolayo ezifana nephepha kunye ne-PLA, ithatha indawo yokupakisha kweplastiki ethambileyo yendabuko kwixesha elidlulileyo. Ukupakisha kudlule kwi-GB/T. Indlela yokumisela ka-19277.1 iqinisekisile ukuba phantsi kweemeko zokwenza umgquba kwimizi-mveliso, inokonakala ngaphezulu kwe-90% kwiinyanga ezi-6, kwaye iya kuba ngamanzi angengobungozi kwibhayoloji, i-carbon dioxide kunye nezinye iimveliso emva kokubola. -
Ukuthunyelwa kwamanye amazwe kwePVC eTshayina kusaqhubeka nokuba phezulu kwisiqingatha sokuqala sonyaka.
Ngokwezibalo zamva nje zerhafu yelizwe, ngoJuni ka-2022, umthamo wokungenisa we-PVC pure powder kwilizwe lam wawuziitoni ezingama-29,900, ukonyuka kwe-35.47% ukusuka kwinyanga ephelileyo kunye nokunyuka kwe-23.21% unyaka nonyaka; ngoJuni ka-2022, umthamo wokuthumela ngaphandle we-PVC pure powder kwilizwe lam wawuziitoni ezingama-223,500, ukwehla kwenyanga nenyanga kwakuyi-16%, kwaye ukonyuka konyaka nonyaka kwakuyi-72.50%. Umthamo wokuthumela ngaphandle waqhubeka nokugcina inqanaba eliphezulu, nto leyo eyanciphisa ukunikezelwa okuninzi kwimarike yasekhaya ukuya kwinqanaba elithile. -
Yintoni iPolypropylene (PP)?
I-Polypropylene (PP) yi-thermoplastic eqinileyo, eqinileyo, nekristale. Yenziwe nge-propene (okanye i-propylene) monomer. Le resin ye-hydrocarbon ethe tye yeyona polymer ilula phakathi kwazo zonke iiplastiki ezithengiswayo. I-PP iza njenge-homopolymer okanye njenge-copolymer kwaye inokwandiswa kakhulu ngezongezo. Isetyenziswa kwiipakethe, kwiimoto, kwizinto zabathengi, kwezonyango, kwiifilimu ezixonxiweyo, njl. I-PP iye yaba yinto ekhethwayo, ingakumbi xa ufuna i-polymer enamandla aphezulu (umz., ngokuchasene ne-Polyamide) kwizicelo zobunjineli okanye ujonge nje ixabiso elingcono kwiibhotile zokubumba (xa kuthelekiswa ne-PET). -
Yintoni iPolyethylene (PE)?
I-Polyethylene (PE), eyaziwa ngokuba yi-polythene okanye i-polyethene, yenye yeeplastiki ezisetyenziswa kakhulu kwihlabathi liphela. Ii-Polyethylene zihlala zinesakhiwo esithe nkqo kwaye zaziwa ngokuba zii-polymers ezongezelelweyo. Ukusetyenziswa okuphambili kwezi polymers zokwenziwa kukwiphakheji. I-Polyethelyne idla ngokusetyenziswa ukwenza iingxowa zeplastiki, iibhotile, iifilimu zeplastiki, izikhongozeli, kunye nee-geomembranes. Kunokuqatshelwa ukuba ngaphezulu kwe-100 yezigidi zeetoni ze-polyethene ziveliswa minyaka le ngeenjongo zorhwebo nezemizi-mveliso. -
Uhlalutyo lokusebenza kwemarike yokuthumela ngaphandle yePVC yelizwe lam kwisiqingatha sokuqala sowama-2022.
Kwisiqingatha sokuqala sowama-2022, imakethi yokuthumela ngaphandle ye-PVC inyukile unyaka nonyaka. Kwikota yokuqala, echatshazelwe kukwehla koqoqosho lwehlabathi kunye nobhubhane, iinkampani ezininzi zasekhaya ezithumela ngaphandle zibonise ukuba imfuno yeediski zangaphandle inciphile. Nangona kunjalo, ukusukela ekuqaleni kukaMeyi, ngokuphuculwa kwemeko yobhubhane kunye nothotho lwamanyathelo aqaliswe ngurhulumente waseTshayina ukukhuthaza ukubuyiselwa koqoqosho, izinga lokusebenza kwamashishini emveliso ye-PVC yasekhaya liphezulu, imakethi yokuthumela ngaphandle ye-PVC ifudumele, kwaye imfuno yeediski zangaphandle inyukile. Inani libonisa umkhwa othile wokukhula, kwaye ukusebenza ngokubanzi kwemarike kuphucukile xa kuthelekiswa nexesha elidlulileyo. -
Isetyenziselwa ntoni i-PVC?
I-polyvinyl chloride (i-PVC, okanye i-vinyl) engabizi kakhulu nesetyenziswa ngeendlela ezahlukeneyo kwizakhiwo nakwezokwakha, kukhathalelo lwempilo, kwi-elektroniki, kwiimoto nakwamanye amacandelo, kwiimveliso ezisusela kwiipayipi kunye nee-siding, iingxowa zegazi kunye neetyhubhu, ukuya kwi-wire kunye ne-cable insulation, izixhobo zenkqubo ye-windshield kunye nokunye.
