Isici esibalulekile okufanele usicabangele lapho ukhetha amalensi yizinto zelensi.
Ipulasitiki kanye ne-polycarbonate yizinto ezivamile zelensi ezisetshenziswa ezigqokweni zamehlo.
Ipulasitiki ilula futhi ihlala isikhathi eside kodwa ijiyile.
I-Polycarbonate incane futhi inikeza isivikelo se-UV kodwa iyaklwebheka kalula futhi ibiza kakhulu kunepulasitiki.
Ilensi ngayinye inezimfanelo ezihlukile ezenza ifaneleke kakhulu emaqenjini athile eminyaka, izidingo kanye nendlela yokuphila. Lapho ukhetha ilensi, kubalulekile ukucabangela:
●Isisindo
●Ukumelana nomthelela
●Ukumelana nokuklwebheka
●Ubukhulu
●Isivikelo se-Ultraviolet (UV)
●Izindleko
Ukubuka konke kwamalensi epulasitiki
Amalensi epulasitiki aziwa nangokuthi i-CR-39. Lokhu kusetshenziswa kabanzi ezibukweni zamehlo kusukela ngawo-1970 futhi kuseyindlela ethandwayo phakathi kwabantu abagqoka izibuko zikadokotela ngenxayayoizindleko eziphansi kanye nokuqina. Isembozo esingaklwebhi, umbala kanye nesembozo esivikela i-ultraviolet (UV) singafakwa kalula kula malensi.
●Elula –Uma kuqhathaniswa nengilazi eyinhloko, ipulasitiki ilula. Izibuko ezinamalensi epulasitiki zikhululekile ukuzigqoka isikhathi eside.
●Ukucaca okuhle kokukhanya –Amalensi epulasitiki anikeza ukucaca okuhle kokukhanya. Awabangeli ukuphazamiseka okukhulu kokubona.
●Ihlala isikhathi eside –Amalensi epulasitiki awavamile ukuphuka noma ukuphuka njengengilazi. Lokhu kuwenza abe ukukhetha okuhle kubantu abakhuthele, yize engavimbeli ukuqhekeka njenge-polycarbonate.
●Kubiza kancane –Amalensi epulasitiki ngokuvamile abiza kancane kakhulu kune-polycarbonate.
●Ukuvikelwa kwe-UV okuyingxenye –Ipulasitiki inikeza isivikelo esiyingxenye kuphela emisebeni ye-UV eyingozi. Ukwembozwa kwe-UV kufanele kwengezwe ukuze kuvikelwe ngokuphelele uma uhlela ukugqoka izibuko ngaphandle.
Ukubuka konke kwamalensi e-polycarbonate
I-Polycarbonate uhlobo lwepulasitiki engathinteki kakhulu evame ukusetshenziswa ezindongeni zamehlo. Amalensi okuqala e-polycarbonate athengiswayo aqalwa ngawo-1980, futhi asheshe athandwa kakhulu.
Le nto yelensi inamandla okuphikiswa ngokuphindwe kayishumi kunepulasitiki. Ngenxa yalesi sizathu, ivame ukunconywa ezinganeni nakubantu abadala abakhuthele.
●Kuhlala isikhathi eside –I-Polycarbonate ingenye yezinto eziqine kakhulu neziphephile ezisetshenziswa namuhla ezingilazini. Ivame ukunconywa ezinganeni ezincane, abantu abadala abakhuthele, kanye nabantu abadinga izibuko zokuphepha.
●Mncane futhi ulula –Amalensi e-polycarbonate mancane ngamaphesenti angama-25 kunepulasitiki yendabuko.
●Ukuvikelwa okuphelele kwe-UV –I-Polycarbonate ivimba imisebe ye-UV, ngakho-ke asikho isidingo sokwengeza ungqimba lwe-UV ezingilazini zakho. La malensi ayisinqumo esihle kubantu abachitha isikhathi esiningi bengaphandle.
●Kunconywa ukugqoka okumelana nokuklwebheka –Nakuba i-polycarbonate ihlala isikhathi eside, le nto isalokhu isengozini yokuklwebheka. Kunconywa ukugqoka okungaklwebheki ukuze kusize la malensi ahlale isikhathi eside.
●Kunconywa ukugqoka okuvimbela ukukhanyisa –Abanye abantu abanemithi ephakeme babona ukubonakaliswa kobuso kanye nokufiphazwa kombala lapho begqoke amalensi e-polycarbonate. Kunconywa ukugqoka upende oluvimbela ukubonakaliswa ukuze kuncishiswe lo mphumela.
●Umbono ophambene –I-Polycarbonate ingabangela umbono ophambene ongaphandle kwalabo abanemithi enamandla.
●Ibiza kakhulu -Amalensi e-polycarbonate ngokuvamile abiza kakhulu kunamalensi epulasitiki.
