Ngokwezibalo ezikhoyo, amandla okuvelisa ibhodi yokuthintela amanzi e-China isondele kwiitoni ezingama-2,000 ngenyanga ngo-2023, okunyuka kakhulu xa kuthelekiswa neetoni ezingama-800 ngenyanga kunyaka ophelileyo.Nangona kunjalo, umthamo onjalo ubalelwa kuphela umlinganiselo omncinci kwishishini leebhodi zaseTshayina.Ibhodi yothintelo olusekwe emanzini e-China ikakhulu yeyokupakisha ukutya, kwaye ikakhulu ithengisela imarike yaphesheya.Ukuba iyakugcina ukukhula okunempilo kwixesha elizayo kuxhomekeke kakhulu kukhetho lomgaqo-nkqubo ekhaya nakumazwe angaphandle.
Ukusuka apho simi khona, nantsi iindlela eziphambili zebhodi yothintelo olusekwe emanzini.
Abathengi kule mihla abasaneliseki ngumgangatho womqobo ophakathi.Bajonge izisombululo ezilungiselelwe ukwenza umsebenzi wokupakisha ogqwesileyo kwizicelo ezahlukeneyo.Ibhodi kufuneka ibe lulwelo kunye negrisi ukumelana neempawu ezilungelelanisiweyo ezifana nesantya sokuhambisa umphunga osezantsi (MVTR) okanye izinga lokuhanjiswa kweoksijini esezantsi (OTR), ezifunekayo ekufuneni ukusetyenziswa kokuphela.Ngokomzekelo, i-OTR, ephantsi njenge-0.02 cm3 / m2 / ngosuku ukuza kuthi ga ngoku, ikhethwa kwi-package yeziqhamo ezomisiweyo.Ngokunjalo, ukupakishwa kwezixhobo zomgubo kufuna iMVTR ephantsi.Traditional acrylic dispersion inokubonelela kuphela amaxabiso MVTR phakathi 100 ukuba 200g/m 2 / ngosuku, kodwa High Performance Barrier (HPB) dispersion anganika ixabiso MVTR ngaphantsi 50g/m 2 / ngosuku okanye nokuba 10g/m 2 / ngosuku.
Ukutshintshela kancinci kancinci kwi-HPB ukusuka kwiplastiki kuye kwangqinwa ngokunyuka kokusetyenziswa kwebhodi yeHPB kwinqanaba lemizi-mveliso.Ngokungafaniyo nopakisho lokutya oluluxhalabele kakhulu ukhuseleko, ukupakishwa kwamashishini kugxininisa ukusebenza komqobo kunye neendleko zemveliso.Ukupakishwa kwe-HPB kunokohlulwa kube kupakisho oluninzi lwemizi-mveliso kunye nokupakishwa kwemveliso yemichiza yemihla ngemihla.Ukupakishwa kwe-industrial bulk kubhekiselele kuzo zonke iindidi zeengxowa zevalvu ezisetyenziselwa ukubamba imathiriyeli yegranular, njengesamente kunye nomgubo wekhemikhali.Iingxowa zevalve yamaphepha zidla ngokufumaneka ngokobukhulu obungama-25 kg okanye ama-50 kg.Umqobo osekelwe emanzini, njengenye indlela ezinzileyo kwiplastiki, inokuqinisekisa ukutywinwa kobushushu kunye nexabiso le-MVTR ukuxhasa ngokugqwesileyo ukupakishwa kweengxowa zevalve yephepha kwimveliso enesantya esiphezulu.Iinkampani ezingoovulindlela ezikhuthaza uphuhliso lweemveliso zeHPB ziquka iAlou, BASF, kunye neCovestro.I-HPB inokubonelela ngokusebenza komqobo onqwenelekayo kodwa inzuzo yayo nayo inorhwebo.Iindleko zemveliso ngomnye wemiqobo ekukhuleni kwayo kwimarike.Ukupakishwa kwemveliso yeekhemikhali yemihla ngemihla kubhekiselele ekupakishweni kweemveliso ezifana nesefu, ishampu, kunye nokhathalelo lwesikhumba, uninzi lwazo ziingxowa ezingamakhulu aliqela eegram ukuya kwiikhilogram ezimbini.Ukupakishwa kwemveliso yeekhemikhali yemihla ngemihla kufuna ngakumbi ngokwemiqathango yokusebenza komqobo kuneengxowa zevalvu.Ifuna iimpawu ezibalulekileyo ezifana nokulawula ukufuma, ukungangeni komoya kunye nokukhusela ukukhanya.
Xa kujongwa inyani yokuba iiplastiki azinakonakala, izinto ezivuselelekayo zijongwa ngokuthandwa ngabathengi abaqaphela indalo kunye neempawu, ezona zininzi ziyimiqobo esekwe kwibhayoloji.Kangangonyaka, abavelisi abambalwa baphehlelele ezabo iimveliso zokusasazwa kwebhayoloji, bekhuthaza ukusetyenziswa kumashishini ahlukeneyo, ngakumbi ishishini lokupakisha ukutya.Ukusuka kwi-barrier dispersion ukuya kwii-inki zokuprinta, umxholo we-bio-based wemveliso uphakathi kwe-30% kunye ne-90%.Ukuqaliswa kwezixhobo ze-nanocellulose kwandisa ngakumbi iphothifoliyo yezithintelo ze-bio-based.Iinkampani ezinikezela ngeengubo ezibolayo ezibolayo ziquka iBasf, iCovestro, iSiegwerk, iWanhua, iShengquan, iQihong, iTangju njalo njalo.Uphando luye lwenziwa kwizicelo ezininzi kunye namashishini, kubandakanywa ukwenza iphepha, iingubo, iikhemikhali zemihla ngemihla kunye neebhetri zamandla.Nangona kunjalo, uninzi lophando lujongwa njengeliphezulu kweli nqanaba, uphononongo olunzulu kunye nophando luyafuneka ngokucacileyo.Uphando lwethiyori kunye nokusetyenziswa okusebenzayo kufuneka kusebenzisana ngokusondeleyo omnye nomnye.Uphononongo kunye nophando kufuneka ludlule ngaphaya kweCellulose Nanofibrils (CNF) okanye i-Microfibrillated cellulose (MFC), ukwenzela ukubonelela ngeendlela ezininzi zokukhetha abathengi ukuba bakhethe eyona inokuxhasa ngokufanelekileyo imfuno yabo yokupakisha.
I-80% yemfuno yemveliso yesithintelo ezinzileyo ivela kwiimarike zaphesheya zase-China, ezifana neYurophu, uMntla Melika kunye ne-Australia.Imfuno yebhodi yesithintelo esekwe emanzini kwimarike yase-Australia ikhule kakhulu kule minyaka idlulileyo.Umgaqo-nkqubo wothintelo lweplastiki eHong Kong nawo ube negalelo ekukhuleni kwebhodi yothintelo olusekelwe emanzini.Imfuno yayo yasekhaya e-China ibuthathaka ngoku.Uphuhliso lwe-aqueous dispersion coating aluxhomekekanga kuphela kwiinzame ze-brand kodwa nakumgaqo-nkqubo woshishino.Kulo nyaka uphelileyo, amagunya asekuhlaleni e-China atshintshile ekukhuthazeni iplastiki enokubola ukuya kwezinye iindlela ezingafaniyo zeplastiki, ingakumbi izinto ezinokuphinda zisetyenziswe nezinokuhlaziywa.
