Kunezinkulungwane zezinkomishi zamanzi epulasitiki, yiziphi izinto okufanele uzikhethe ukuze uzizwe uphephile?Okwamanje, kunezinto ezinhlanu ezibalulekile zezinkomishi zamanzi zepulasitiki emakethe: I-PC, i-tritan, i-PPSU, i-PP, ne-PET.
❌Awukwazi ukukhetha: I-PC, i-PET (ungakhethi izinkomishi zamanzi zabantu abadala nezingane)
I-PC ingakhulula kalula i-bisphenol A uma ishisa, futhi i-bisphenol A ingabangela ukuphazamiseka kwe-endocrine, iphazamise isimiso sokuzala, futhi ibangele ukuthomba ngaphambi kwesikhathi ezinganeni. Umuthi we-D ophumayo nophumayo!
I-PET inokumelana nezinga lokushisa elingu-65℃. Uma izinga lokushisa elilinganiselwe selidlulile, lingakhulula kalula izinto eziyingozi. Ucwaningo lwesayensi luthole ukuthi imikhiqizo yepulasitiki ye-PET ingakhulula i-carcinogens phakathi nenyanga eyodwa yokusetshenziswa futhi inobuthi emasendeni abesilisa.
✅Kuyatholakala ongakhetha kukho: I-Tritan, PPSU, PPTritan material ayiqukethe i-bisphenol A, bisphenol S nanoma yiziphi izinto ze-bisphenol, futhi iphephe kakhulu. Kodwa-ke, ukumelana nezinga lokushisa kwe-tritan kungu-10-96 ° C, ngakho-ke akunconywa ukufaka amanzi ashisayo angu-100-degree.
I-PPSU iyinto entsha ephephile, i-polyphenylsulfone, engaqukethe i-bisphenol A. Isakhiwo sayo sangaphakathi sizinzile futhi singamelana nokuvalwa kwe-180-degree high-temperature eqhubekayo. Iphinde imelane kakhulu nokuwa, ngoba umzimba webhodlela ulula futhi akulula ukuphahlazeka.
Amabhodlela ezingane nezinkomishi zamanzi ezenziwe ngezinto ze-ppsu ngeke zikhiqize izinto ezinobuthi ngemva kokuvala inzalo okuphindaphindwayo kwezinga lokushisa eliphezulu. Aziqukethe i-bisphenol A futhi zingamelana nezinga lokushisa eliphakeme elingu-180 degrees. Ngakho-ke, uma ujwayele ukugcina amanzi ashisayo noma izinga lokushisa eliphezulu lokubulala amagciwane, izinto ze-PPSU ziyinketho yokuqala.
Izinkomishi zamanzi zepulasitiki ze-PP zenziwe nge-polypropylene, ezinokuzinza okuhle kokushisa nokufakwa kwe-insulation, iphephile futhi ayinabungozi emzimbeni womuntu. Kodwa-ke, kufanele kuqashelwe ukuthi izinkomishi zamanzi ezenziwe nge-PP azikwazi ukuqhuma emazingeni okushisa aphezulu isikhathi eside, ngaphandle kwalokho zizobangela ukuguga kalula.
Ake sibheke ukuthi inkomishi yakho yamanzi yenziwe ngani?
