Kunezinhlobo eziningi zezinto zokwakha amaketela, ngayinye inezinzuzo zayo kanye nokubi, kodwa iyiphi impahla elungele umzimba?Namuhla, umhleli uzokunikeza isayensi edumile.
Amaketela ahlukaniswa kakhulu abe yizigaba ezi-5 ezilandelayo:
(1) Amaketela e-Ceramic namaketela engilazi kancane kancane adonse ukunaka kwabathengi ngenxa yobuhle bawo kanye nezinzuzo zokuvikela imvelo.Nokho, ukushiyeka kwabo kuyabonakala, okungukuthi, baphuka kalula.
(2) Amaketela okusansimbi ashibhile futhi aqukethe i-trace element iron enenzuzo emzimbeni womuntu.Kodwa-ke, ngenxa yethonya lezinto ezibonakalayo, ukunambitheka kwamanzi akukuhle kakhulu, futhi kulula ukugqwala.
(3) Lapho igedlela lepulasitiki liqala ukuvela, lalisathandwa iqembu labantu ngoba likwazi ukubilisa amanzi ngokushesha futhi lisize abantu bonge isikhathi.Kodwa-ke, abantu baqala ukuzwa ukuthi iphunga lepulasitiki elingamukeleki elikhiqizwa ngesikhathi sokushisa ayamukeleki, nokuthi izingxenye ze-plasticizer ezikhiqizwa ukushisa ziyingozi empilweni yomuntu.
(4) Amaketela ethusi ne-aluminium anomphumela ongcono kakhulu wokudlulisa ukushisa, kodwa ngokombono wokuphepha, womabili amaketela ethusi nawe-aluminium aqukethe izinto eziyingozi emzimbeni womuntu, ezingalungeli ukusetshenziswa isikhathi eside.
(5) Iketela lensimbi engagqwali njengamanje liwuhlobo lomkhiqizo olusetshenziswa kakhulu emakethe.Igobolondo lensimbi engagqwali liqinile futhi liqinile, lihambisana nenani elifanele, ukusebenza kahle kokudlulisa ukushisa, futhi igedlela lensimbi engagqwali yezinga lokudla lihlangabezana nezidingo zokuphepha kokudla kuzwelonke, ngeke likhiqize imiphumela emibi enobuthi, livikele impilo nokuphepha kwabathengi, futhi ithandwa imindeni eminingi.
Ngakho-ke, ngokubheka izinto ezingenhla, iketela lensimbi engenasici ingenye yezinqumo ezingcono kakhulu.
Uma ukhetha iketela lensimbi engagqwali, ungakhethi insimbi eshibhile, kufanele ukhethe izinhlobo ezithile ezaziwayo, ngoba awunasibopho somzimba wakho.Isibonelo, abakhiqizi bethu bokufakwa kwamapayipi ensimbi engenasici ye-Gangzheng basebenzisa ukufakwa kwamapayipi ensimbi engagqwali ebangeni lokudla 304, okungaqinisekisa ukuphepha nempilo yekhwalithi yamanzi.
