Emizini eminingi,izitsha zepulasitikiziyithuluzi elivamile lemisebenzi ehlukahlukene, kusukela ekuwasheni izitsha ukuya ekuwasheni izingubo. Ayisindi, ayathengeka, futhi kulula ukuwagcina, okuwenza abe yisinqumo esidumile semisebenzi yansuku zonke. Kodwa-ke, umbuzo ovame ukuvela ukuthi kuphephile yini ukuthela amanzi abilayo endishini yepulasitiki. Impendulo yalo mbuzo incike ezicini eziningana, okuhlanganisa uhlobo lwepulasitiki, izinga lokushisa lamanzi, nokusetshenziswa okuhlosiwe. Ukuqonda lezi zici kubalulekile ekuqinisekiseni kokubili ukuphepha nokuphila isikhathi eside kwemikhiqizo yakho yepulasitiki.
Izinhlobo Zepulasitiki Nokumelana Nokushisa Kwazo
Akuwona wonke amapulasitiki adalwe alinganayo. Izinhlobo ezahlukene zamapulasitiki zinamazinga ahlukahlukene okumelana nokushisa, okunquma ukuthi zingawabamba ngokuphephile amanzi abilayo. Izitsha eziningi zepulasitiki zenziwe ngezinto ezifana ne-polyethylene (PE), i-polypropylene (PP), noma i-polyvinyl chloride (PVC). Ngayinye yalezi pulasitiki inephuzu elithile lokuncibilika kanye nezinga lokumelana nokushisa.
- I-Polyethylene (PE):Lena enye yepulasitiki evamile esetshenziswa ezintweni zasendlini. Ngokuvamile akunconywa ukuveza i-PE emanzini abilayo, njengoba indawo yayo yokuncibilika isukela ku-105°C kuya ku-115°C (221°F kuya ku-239°F). Amanzi abilayo, ngokuvamile ku-100°C (212°F), angabangela i-PE ukuthi isonte, ithambe, noma incibilike ngokuhamba kwesikhathi, ikakhulukazi uma ukuchayeka kunwetshiwe.
- I-Polypropylene (PP):I-PP ikwazi ukumelana nokushisa kune-PE, enephuzu lokuncibilika elicishe libe ngu-130°C kuya ku-171°C (266°F kuya ku-340°F). Iziqukathi eziningi zepulasitiki kanye ne-kitchenware zenziwe nge-PP ngoba zingakwazi ukumelana namazinga okushisa aphezulu ngaphandle kokukhubazeka. Nakuba i-PP ingakwazi ukuphatha amanzi abilayo kangcono kune-PE, ukuchayeka okuqhubekayo emazingeni okushisa abilayo kusengenza buthaka izinto ngokuhamba kwesikhathi.
- I-Polyvinyl Chloride (PVC):I-PVC inephuzu elincibilikayo eliphansi, ngokuvamile eliphakathi kuka-100°C kuya ku-260°C (212°F kuya ku-500°F), kuye ngokuthi izithasiselo ezisetshenziswa ngesikhathi sokukhiqiza. Kodwa-ke, i-PVC ngokuvamile ayisetshenziselwa iziqukathi ezingase zivezwe emanzini abilayo ngoba ingakhulula amakhemikhali ayingozi, ikakhulukazi uma evezwe ekushiseni okuphezulu.
Izingozi Ezingenzeka Zokusebenzisa Amanzi Abilayo Ezitsheni Zepulasitiki
Ukuthela amanzi abilayo endishini yepulasitiki kungase kube izingozi eziningana, kokubili kumcengezi ngokwawo nakumsebenzisi. Lezi zingozi zihlanganisa:
**1.Ukuncibilika noma i-Warping
Ngisho noma isitsha sepulasitiki singancibiliki ngokushesha lapho sichayeka emanzini abilayo, singasonteka noma singasakheki kahle. I-Warping ingase ibeke engcupheni ubuqotho besakhiwo somcengezi, ikwenze kube lula ukuqhekeka noma ukuphuka esikhathini esizayo. Lokhu kuyiqiniso ikakhulukazi kumapulasitiki ekhwalithi ephansi noma izitsha ezingakhelwanga ngokuqondile ukumelana namazinga okushisa aphezulu.
**2.I-Chemical Leaching
Okunye okukhathazayo okuyinhloko lapho kuvezwa ipulasitiki emazingeni okushisa aphezulu ukuthi kungenzeka kube khona ukucwiliswa kwamakhemikhali. Amapulasitiki athile angakhipha amakhemikhali ayingozi, njenge-BPA (bisphenol A) noma ama-phthalates lapho echayeke ekushiseni. Lawa makhemikhali angangcolisa amanzi futhi abe yingozi empilweni uma ewagwinyile noma ehlangana nokudla noma isikhumba. Nakuba imikhiqizo eminingi yesimanje yepulasitiki ingenayo i-BPA, kusabalulekile ukucabangela uhlobo lwepulasitiki nokuthi yakhelwe uketshezi olushisayo yini.
**3.Ubude bokuphila bufinyeziwe
Ukuchayeka ngokuphindaphindiwe emanzini abilayo kungehlisa izinga lepulasitiki ngokuhamba kwesikhathi. Ngisho noma umcengezi ungabonisi izimpawu zokulimala ngokushesha, ukucindezeleka okuphindaphindiwe okuvela emazingeni okushisa aphezulu kungabangela ukuba ipulasitiki ibe yi-brittle, ikhulise amathuba okuqhekeka noma amakhefu ngokusetshenziswa okuvamile.
Ezinye Izindlela Eziphephile Zemigqomo Yepulasitiki
Uma kubhekwa izingozi ezingaba khona, kuyatuseka ukusebenzisa izinto eziklanyelwe ngokukhethekile ukusingatha amanzi abilayo. Nazi ezinye izindlela eziphephile:
- Izitsha Zensimbi Engagqwali:Insimbi engagqwali imelana kakhulu nokushisa futhi ayifaki ingozi yokucwiliswa kwamakhemikhali. Iqinile, kulula ukuyihlanza, futhi ingabamba ngokuphephile amanzi abilayo ngaphandle kwengozi yokuncibilika noma ukugoqa.
- Ingilazi Engangeni Ukushisa noma Iceramic:Ngemisebenzi ethile, ingilazi engavimbeli ukushisa noma izitsha ze-ceramic nazo ziyinketho enhle. Lezi zinto zingakwazi ukumelana namazinga okushisa aphezulu futhi zivame ukusetshenziswa emakhishini emisebenzini ehlanganisa uketshezi olushisayo.
- I-Silicone Basins:I-silicone yekhwalithi ephezulu enye impahla ekwazi ukuphatha amanzi abilayo. Izitsha ze-silicone ziyaguquguquka, azikwazi ukumelana nokushisa, futhi azifaki amakhemikhali ayingozi. Nokho, awavamile futhi angase angafaneleki kuzo zonke izinhlobo zemisebenzi yasendlini.
Uma Kufanele Usebenzise Ipulasitiki
Uma udinga ukusebenzisa umcengezi wepulasitiki futhi ukhathazekile ngekhono lawo lokuphatha amanzi abilayo, cabangela lezi zinyathelo zokuphepha ezilandelayo:
- Pholisa Amanzi Kancane:Vumela amanzi abilayo ukuthi aphole imizuzu embalwa ngaphambi kokuwathela endishini yepulasitiki. Lokhu kunciphisa izinga lokushisa ngokwanele ukunciphisa ingozi yokulimaza ipulasitiki.
- Sebenzisa Ipulasitiki Engangeni Ukushisa:Uma kufanele usebenzise ipulasitiki, khetha indishi eyenziwe ngezinto ezikwazi ukumelana nokushisa njenge-polypropylene (PP). Ngaso sonke isikhathi hlola izinkombandlela zomkhiqizi ukuze uqinisekise ukuthi umcengezi ulinganiselwe ukusetshenziswa kwezinga lokushisa eliphezulu.
- Umkhawulo Wokuchayeka:Gwema ukushiya amanzi abilayo endishini yepulasitiki isikhathi eside. Thela amanzi, qedela umsebenzi wakho ngokushesha, bese uthulula indishi ukuze unciphise isikhathi upulasitiki uchayeka ekushiseni okuphezulu.
Isiphetho
Nakuba izitsha zepulasitiki zilula futhi ziguquguquka, azizona njalo inketho engcono kakhulu yokubamba amanzi abilayo. Uhlobo lwepulasitiki, ubungozi bokucwiliswa kwamakhemikhali, namandla omonakalo konke kwenza kubaluleke ukucabangela ezinye izindlela eziphephile njengensimbi engagqwali, ingilazi, noma i-silicone. Uma usebenzisa indishi yepulasitiki, ukuthatha izinyathelo zokuphepha ezifanele kungasiza ekunciphiseni izingozi futhi kunwebe ukuphila komcengezi wakho, kuqinisekise ukusetshenziswa okuphephile nokuphumelelayo ekhaya lakho.
