Ukuphepha nokuqina kuyizici ezimbili ezibalulekile abazali nabanakekeli abazikhathalelayo lapho bekhetha izinto ezifanele zemishini yokudlala yasengadini yezingane. Yilapho amashidi epulasitiki e-HDPE anemibala emibili efika khona futhi anikeze ikhambi elifanele.
I-HDPEI-polyethylene, eyaziwa nangokuthi i-polyethylene enobuningi obukhulu, iyinto yepulasitiki esetshenziswa kabanzi eyaziwa ngamandla ayo nokuqina kwayo. Ayimelani nokushaywa, amakhemikhali kanye nemisebe ye-UV, okwenza ifaneleke ukusetshenziswa ngaphandle. Ukukhanya kwayo kwenza kube lula ukuyiphatha nokuyithutha, okwengeza ekulula kwayo.
Esinye sezici eziphawulekayo ze-Ishidi lepulasitiki elinemibala emibili le-HDPEiyisakhiwo sesangweji esinezingqimba ezintathu. Lokhu kwakhiwa kunikeza amandla engeziwe nokuqina kumashidi, kuqinisekisa ukuthi angakwazi ukumelana nokunyakaza okunamandla kanye nezimo zezulu ezinzima. Futhi kwenza amashidi angaguquki futhi agobe, okuqinisekisa ukuphepha kwezingane ngenkathi zidlala.
Lawa maphaneli epulasitiki anemibala emibili awagcini nje ngokusebenza kodwa futhi amahle. Ngemibala yawo egqamile kanye nokuqedwa okubushelelezi, athuthukisa ukubukeka kwemishini yokudlala yasengadini yezingane. Angabunjwa kalula abe yizimo nobukhulu obuhlukahlukene, okuvumela abakhiqizi ukuthi bakhe imiklamo ekhangayo edonsa ukunaka kwezingane.
Ngaphezu kwalokho,Ishidi lepulasitiki elinemibala emibili le-HDPEinobungani nemvelo futhi iyasimeme. Azinazo izinto eziyingozi ezifana nomthofu namakhemikhali, okugcina izingane ziphephile ngenkathi futhi zinegalelo endaweni enempilo. Ukuphila kwazo isikhathi eside kanye nokumelana nokuguguleka nakho kusho ukuthi zihlala isikhathi eside, kunciphisa isidingo sokushintsha njalo futhi kunciphisa ukukhiqizwa kwemfucuza.
Ngokuphathelene nokugcinwa, lawa maphaneli epulasitiki kulula kakhulu ukuwahlanza. Ukusula okulula ngamanzi anensipho kwanele ukuwagcina ebukeka sengathi masha. Aphinde amelane namabala kanye nemidwebo, okuyinzuzo eyengeziwe ezindaweni zomphakathi nasezindaweni zokudlala.
Uma uthenga amashidi epulasitiki anemibala emibili e-HDPE emishini yokudlala yabantwana engadini, kubalulekile ukuqinisekisa ukuthi izinto zihambisana nezindinganiso zokuphepha kanye nemithethonqubo. Bheka izitifiketi ezifana ne-ASTM kanye ne-EN71, eziqinisekisa ukuthi ibhodi lihlolwe amandla omshini, ukungabi nobuthi kanye nokumelana nomlilo.
Ekuphetheni,I-HDPEIshidi lepulasitiki elinemibala emibili liyisinqumo esihle kakhulu semishini yokudlala yasengadini yezingane. Ukwakhiwa kwazo kwesangweji ezinezingqimba ezintathu kuhlanganiswe namandla nokuqina kwe-HDPE kuqinisekisa ukuthi zihlala isikhathi eside futhi ziphephile ezinganeni zokudlala ngazo. Zinemibala, kulula ukuzinakekela, futhi zinobungani nemvelo, lawa mashidi aqinisekile ukuthi azothuthukisa ukubukeka nokusebenza kwanoma iyiphi indawo yokudlala yangaphandle. Thenga amabhodi epulasitiki anemibala emibili e-HDPE manje bese uletha ulwazi lokudlala oluphephile nolujabulisayo ezinganeni.
