Ukuhlaziywa kokuphepha kwezinkomishi zamanzi ezibonakalayo ze-PC+PP

Njengoba ukuqwashisa ngempilo kwabantu kuqhubeka nokwanda, ukukhethwa kwezinto ezibonakalayo zezinkomishi zamanzi sekuphenduke isihloko esikhathazayo kakhulu. Izinto ezivamile zenkomishi yamanzi emakethe zihlanganisa ingilazi, insimbi engagqwali, ipulasitiki, njll. Phakathi kwazo, izinkomishi zamanzi epulasitiki zithandwa kakhulu ngenxa yokukhanya kwazo nokuqina. I-PC (i-polycarbonate) ne-PP (i-polypropylene) yizinto ezimbili ezivamile zepulasitiki. Eminyakeni yamuva nje, izinkomishi zamanzi ezenziwe ngezinto ezihlanganisiwe ze-PC+PP ziye zangena kancane kancane emakethe. Ngakho-ke, ingabe izinkomishi zamanzi ezenziwe nge-PC+PP ziphephile? Lesi sihloko sizokwenza ukuhlaziya okuningiliziwe okuvela ezicini eziningi ezifana nezici ezibonakalayo, ukuphepha kokusetshenziswa, nemiphumela yezempilo.

1. Ukuhlaziywa kwezinto ezibonakalayo kwe-PC (polycarbonate).

1. Izinto ezibonakalayo

• Ukukhanya okuphezulu: Impahla ye-PC inokucaca okuhle futhi ibukeka njengengilazi, kodwa ilula ngesisindo.

• Ukumelana nomthelela onamandla: Impahla ye-PC inokumelana nomthelela omuhle kakhulu futhi akulula ukuphuka. Ifanele ukwenza imikhiqizo edinga amandla aphezulu.

• Ukumelana nokushisa okuhle: Impahla ye-PC inokumelana nokushisa okuhle futhi ngokuvamile ingamelana nezinga lokushisa elingu -40°C kuya ku-120°C.

2. Ingxabano yezokuphepha

• Inkinga ye-Bisphenol A (BPA): Ikhemikhali, i-bisphenol A (BPA), isetshenziswa ekukhiqizeni izinto ze-PC. Ucwaningo lubonisa ukuthi i-BPA ingase iphazamise uhlelo lwe-endocrine lomuntu, ngaleyo ndlela ibe nomthelela empilweni. Ngakho-ke, ukuphepha kwezinto ze-PC bekulokhu kunempikiswano.

• Imikhawulo yokulawula: Amazwe amaningi nezifunda ziye zabeka imingcele eqinile ekusetshenzisweni kwe-BPA. Isibonelo, i-European Union kanye ne-United States bayakwenqabela ukusetshenziswa kwezinto ze-PC ezine-BPA emikhiqizweni yosana neyengane.

2. Ukuhlaziywa kwezinto ezibonakalayo kwe-PP (polypropylene).
1. Izinto ezibonakalayo

• Ukumelana nokushisa okuqinile: Impahla ye-PP inokumelana nokushisa okuhle kakhulu futhi ingamelana nezinga lokushisa elingu--20°C kuya ku-120°C. Ilungele ukwenza i-microwave tableware nezinkomishi zamanzi ashisayo.

• Ukuzinza okuhle kwamakhemikhali: Izinto ze-PP zinokuzinza okuhle kwamakhemikhali, azikwazi ukumelana ne-asidi ne-alkali, futhi azijwayele ukuhlangana namakhemikhali nezinye izinto.

• Ayinabuthi futhi ayinambitheki: Impahla ye-PP ayinabo ubuthi, ayinambitheki futhi ayinazo izinto eziyingozi. Isetshenziswa kakhulu ekufakweni kokudla, imishini yezokwelapha neminye imikhakha.

2. Izinzuzo zokuphepha

• Okungenayo i-BPA: Okubalulekile kwe-PP akuqukethe i-bisphenol A (BPA), ngakho kunezinzuzo eziningi kunempahla ye-PC ngokokuphepha.

• Isitifiketi sezinga lokudla: Imikhiqizo eminingi ye-PP isiphumelele isitifiketi sezinga lokudla, okufakazela ukuphepha kwayo lapho ithintana nokudla.

3. Inkomishi yamanzi eyenziwe nge-PC+PP eyinhlanganisela yezinto
1. Umqondo wokuklama

• Izinzuzo ezihambisanayo: Ibhodlela lamanzi elenziwe ngezinto ezihlanganisiwe ze-PC+PP lenzelwe ukuhlanganisa izinzuzo zezinto ezimbili. Inokubonakala okuphezulu kanye nokumelana nomthelela wezinto ze-PC kanye nokumelana nokushisa nokuqina kwamakhemikhali wezinto ze-PP.

• Ukuguquguquka: Le nkomishi yamanzi eyinhlanganisela ngokuvamile iklanywa ngesakhiwo esinezendlalelo ezimbili, nesendlalelo sangaphakathi esenziwe ngezinto ze-PP kanye nesendlalelo sangaphandle esenziwe ngezinto ze-PC ukuze kuthuthukiswe ukusebenza konke kanye nolwazi lokusebenzisa inkomishi yamanzi.

2. Inqubo yokukhiqiza

• Ubuchwepheshe obuhlanganisiwe: Ibhodlela lamanzi eliyinhlanganisela ye-PC+PP lisebenzisa ubuchwepheshe obuyinhlanganisela obuphambili ukuhlanganisa izinto ezimbili ngenqubo ethile ukuze kuqinisekiswe inhlanganisela eqinile nokuzinza phakathi kwezinto.

• Ukuxhumeka okungenamthungo: Ngokuklama isikhunta esinembayo kanye nobuchwepheshe bokucubungula, izendlalelo zangaphakathi nezangaphandle zenkomishi yamanzi zixhunywe ngaphandle komthungo ukuze kugwenywe izinkinga zokusetshenziswa ezibangelwa ukuhlukaniswa kwezinto.

4. Ukuhlaziywa kokuphepha kwezinkomishi zamanzi ezibonakalayo ze-PC+PP

1. Imiphumela yezempilo

• Ukulawula ubungozi kwe-BPA: Njengoba izinto ze-PC zingaqukatha i-BPA, lapho ukhetha inkomishi yamanzi eyinhlanganisela ye-PC+PP, kufanele unake ukukhetha imikhiqizo ephawulwe ngophawu oluthi “BPA Free” (bisphenol A-free) ukuze uqinisekise impilo nokuphepha kwayo.

• Isiqinisekiso sempahla ye-PP: Impahla ye-PP ngokwayo ayinabo ubuthi, ayinambitheki futhi ayinazo izinto eziyingozi. Njengento engaphakathi kwesendlalelo, ithintana ngqo namanzi neziphuzo, ezinganciphisa ngempumelelo izingozi zezempilo.

2. Ukumelana nokushisa

• Ukusetshenziswa kwezinga lokushisa eliphezulu: Izinkomishi zamanzi eziyinhlanganisela ze-PC+PP ngokuvamile zingamelana namazinga okushisa aphakeme, zifanele ukubamba amanzi ashisayo neziphuzo ezishisayo, futhi akulula ukukhubazeka noma ukukhulula izinto eziyingozi phakathi nokusetshenziswa.

• Sebenzisa kuhhavini we-microwave: Ngenxa yokumelana kahle nokushisa kwempahla ye-PP, ezinye izinkomishi zamanzi ezenziwe ngezinto eziyinhlanganisela ze-PC+PP zingasetshenziswa kumahhavini ama-microwave, kodwa imiyalelo eqondile emiyalweni yomkhiqizo kufanele ilandelwe ukuze kugwenywe ukushisa ezingeni eliphezulu lokushisa. isikhathi eside.

3. Ukuqina nokuphila kwesevisi

• Ukumelana nomthelela: Ukumelana nomthelela ophezulu wezinto ze-PC kwenza inkomishi yamanzi ingahlehli kakhulu ngesikhathi sokusetshenziswa kwansuku zonke, okwandisa ukuqina nempilo yesevisi yomkhiqizo.

• Ukumelana namakhemikhali: Ukuzinza okuhle kwamakhemikhali wempahla ye-PP kwenza inkomishi yamanzi ibe mancane amathuba okuba ibhekane nokusabela kwamakhemikhali lapho ihlangana neziphuzo ezine-asidi ne-alkaline, igcina ukuzinza nokuphepha kwempahla.

4. Ukuhlanza nokunakekela

• Ukuhlanza kalula: Izinkomishi zamanzi ezenziwe ngezinto eziyinhlanganisela ye-PC+PP ngokuvamile zinendawo ebushelelezi, okungelula ukunamathela kuyo ukungcola futhi kulula ukuyihlanza. Kunconywa ukusebenzisa amanzi afudumele kanye ne-detergent ekuhlanzeni, futhi ugweme ukusebenzisa izinto eziqinile ezifana namabhola ensimbi ukuze uzinwaye.

• Ukuhlola okuvamile: Hlola njalo ukuhlobana phakathi kwezingqimba zangaphakathi nezingaphandle zebhodlela lamanzi ukuze uqinisekise ukuthi akukho ukuxega noma ukuhlukana. Uma kutholakala noma yikuphi ukungahambi kahle, kufanele kushintshwe kusenesikhathi ukuze kuqinisekiswe ukusetshenziswa okuphephile.
5. Iziphakamiso zokuthenga

1. Khetha uhlobo olujwayelekile

• Idumela lomkhiqizo: Khetha izinkomishi zamanzi eziyinhlanganisela ze-PC+PP ezikhiqizwe amabhrendi ahlonishwayo nabakhiqizi ukuze uqinisekise ikhwalithi nokuphepha komkhiqizo.

• Uphawu Lokuqinisekisa: Khetha imikhiqizo eqinisekisiwe yezinga lokudla nelebulwe ngophawu lwe-“BPA Free” ukuze uqinisekise ukuthi ayinazo izinto eziyingozi.

2. Buka incazelo yomkhiqizo

• Imiyalelo yokusetshenziswa: Funda imiyalelo yomkhiqizo ngokucophelela ukuze uqonde ububanzi bokusetshenziswa, izinga lokushisa elimelana nokushisa, izindlela zokuhlanza, njll. zenkomishi yamanzi ukuze uqinisekise ukusetshenziswa okufanele.

• Isevisi yewaranti: Khetha imikhiqizo enikeza isevisi yewaranti ukuze uthole ukusekelwa okufika ngesikhathi ngemva kokuthengisa lapho kuphakama izinkinga zekhwalithi.

3. Izibuyekezo zabathengi

• Impendulo yomsebenzisi: Funda mayelana nokusebenza kwangempela nokuphepha komkhiqizo ngokufunda izibuyekezo nempendulo evela kwabanye abathengi, futhi wenze izinqumo zokuthenga ezinolwazi.

Inkomishi yamanzi eyinhlanganisela ye-PC+PP ihlanganisa ukucaca okuphezulu nomthelela wokumelana nezinto ze-PC nokumelana nokushisa nokuzinza kwamakhemikhali ezinto ze-PP, futhi inokusebenza okuhle kukonke. Kodwa-ke, njengoba impahla ye-PC ingase ibe ne-bisphenol A (BPA), lapho kukhethwa futhi kusetshenziswa amabhodlela amanzi enziwe ngale nto, kufanele kuqashelwe ngokukhethekile ukukhetha imikhiqizo ephawulwe ngelogo ethi “BPA Free” ukuze kuqinisekiswe impilo nokuphepha kwayo. Ngokukhetha okunengqondo nokusetshenziswa, inkomishi yamanzi eyinhlanganisela ye-PC+PP inganikeza ithuluzi lokuphuza eliphephile neliqinile lokuphila kwansuku zonke, okukuvumela ukuba ujabulele okuhlangenwe nakho kokuphuza okunempilo nokuphephile.
