Umbhobho we-ABS:Umbhobho we-ABS yimbhobho ekwaziyo ukumelana nokugqwala, esetyenziswa kakhulu ekucoceni amdaka, amanzi amdaka asekhitshini, nakwezinye iindawo.

Umbhobho wePC:Umbhobho we-polycarbonate (PC) unamandla aphezulu, ubonakala lula, kunye nezinye iimpawu, kwaye ungasetyenziswa kwiindlela ezinkulu, kwiitonela, kwiindlela ezingaphantsi komhlaba, nakwezinye iindawo zokwakha.

Umbhobho we-PA:Umbhobho we-polyamide (PA) usetyenziswa kakhulu kwicandelo lomoya, ioyile, amanzi, kunye nezinye izinto zokuthutha ulwelo. Umbhobho we-PA awudli mhlwa, awudli mhlwa, awudli mxinzelelo, kunye nezinye iimpawu.

Izixhobo ezahlukeneyo zemibhobho yeplastiki zifanelekile kwiindawo ezahlukeneyo. Ngokubanzi, imibhobho yeplastiki ineenzuzo zokuba lula, ixabiso eliphantsi, ukumelana nokugqwala, kulula ukwakhiwa, njl.njl., kwaye ithatha indawo yemibhobho yesinyithi yendabuko kancinci kancinci, kwaye idlala indima ebaluleke ngakumbi kulwakhiwo lwanamhlanje.

Nangona kunjalo, kukho iingxaki eziqhelekileyo ezinokufunyanwa ngexesha lokuveliswa nokucutshungulwa kwemibhobho yeplastiki, kuquka:

Ukunyibilika okungekuhle:Ezinye izinto zeplastiki ezisetyenziswa kwinkqubo yokucubungula, ngenxa yesakhiwo se-molecular chain kunye nezinye izinto, zinokubangela ukuba ukunyibilika kube nzima, nto leyo ebangela ukuba ukugcwaliswa okungalinganiyo kwenkqubo yokubumba okanye yokufunxa inaliti kungangeni mveliso, umgangatho womphezulu onganelisiyo, kunye nezinye iingxaki.

Uzinzo olubi lobukhulu:ezinye zezinto zeplastiki ezisetyenziswa kwinkqubo yokucubungula nokupholisa ziyancipha, nto leyo ekhokelela ekubeni imveliso egqityiweyo ingazinzi kakuhle, okanye itshintshe umbala nezinye iingxaki.

Umgangatho ophantsi womphezulu:Kwinkqubo yokukhupha okanye ukubumba ngenaliti, ngenxa yoyilo olungenangqiqo lwezibumba, ulawulo olungafanelekanga lobushushu bokunyibilika, njl.njl., kunokukhokelela kwiziphene ezifana nokungalingani, amaqamza, imikhondo, njl.njl. kumphezulu weemveliso ezigqityiweyo.

Ukumelana nobushushu okungekuhle:Ezinye izinto zeplastiki ezikrwada zidla ngokuthamba kwaye ziguquguquke xa kushushu kakhulu, nto leyo enokuba yingxaki kwiipayipi ezisetyenziswayo ezifuna ukumelana neendawo ezinobushushu obuphezulu.

Amandla okuxinana angonelanga:Ezinye izinto zeplastiki azinawo amandla aphezulu ngokwazo, nto leyo eyenza kube nzima ukuhlangabezana neemfuno zokuqina kokutsalwa kwezinye izicelo zobunjineli.

Ezi ngxaki zihlala zisonjululwa ngokuphucula iindlela zokwenziwa kwezinto eziluhlaza, ukuphucula iindlela zokucubungula, kunye nokuphucula uyilo lwesikhunta. Kwangaxeshanye, kunokwenzeka ukongeza ii-arhente zokuqinisa ezikhethekileyo, izizalisi, ii-lubricants, kunye nezinye izinto ezincedisayo ukuphucula ukusebenza kokucubungula imibhobho yeplastiki kunye nomgangatho wemveliso egqityiweyo. Kangangeminyaka emininzi, izixhobo zokulungisa i-PPA (Polymer Processing Additive) fluoropolymer ziye zakhethwa ngabaninzi abavelisi bemibhobho njengee-lubricants.

Izithako zokucubungula i-PPA (Polymer Processing Additive) ze-fluoropolymer ekuvelisweni kwemibhobho zisetyenziselwa ukuphucula ukusebenza kokucubungula, ukuphucula umgangatho weemveliso ezigqityiweyo, kunye nokunciphisa iindleko zemveliso. Ngokwesiqhelo zikhona ngohlobo lwezithambiso, kwaye zinokunciphisa ngempumelelo ukumelana nokungqubana, kwaye ziphucule ukunyibilika kunye nokuzaliswa kweplastiki, ngaloo ndlela ziphucula imveliso kunye nomgangatho wemveliso kwinkqubo yokubumba okanye yokujova.

Kwihlabathi liphela, i-PFAS ikwasetyenziswa kakhulu kwiindawo ezininzi zoshishino kunye nabathengi, kodwa iingozi zayo ezinokubakho kwindalo esingqongileyo nakwimpilo yabantu zibangele inkxalabo enkulu. Njengoko i-European Chemicals Agency (ECHA) isenza ukuba imiqathango ye-PFAS ibhengezwe esidlangalaleni ngo-2023, abavelisi abaninzi baqala ukukhangela ezinye iindlela zokuncedisa ukucubungula i-PPA fluoropolymer.
