Ingilazi inokuqina okuphezulu kwamakhemikhali.Njengesitsha sokudla nengilazi yesiphuzo, okuqukethwe ngeke kungcoliswe.Njengomhlobiso noma izidingo zansuku zonke, impilo yomsebenzisi ngeke yonakale.
(Eminyakeni yamuva nje, kutholwe ukuthi i-bisphenol A iyana lapho amabhodlela epulasitiki eshiselwa ku-110 ° C, futhi i-bisphenol A (BPA) iphazamisa uketshezi lwabantu futhi inomthelela omubi kakhulu ezinganeni.
Ngo-Okthoba 2008, iCanada yavala ukuthengiswa kwamabhodlela e-bisphenol A.Ngo-March 2009, i-EU yavala ukukhiqizwa kwamabhodlela epulasitiki aqukethe i-bisphenol A;amabhodlela epulasitiki asetshenziswa ophuzweni oludakayo naseziphuzweni (njengeziphuzo ezinesoda) nawo athela kalula i-bisphenol A, futhi ubhiya ne-bisphenol A kusebenzisana ukuze kwakhe izinto ezinobuthi.Isetshenziswa ekukhiqizeni utshwala Ngemva kweziqukathi zepulasitiki namapayipi epulasitiki, kutholwe amapulasitiki ayingozi ewayini.
I-Antimony ku-catalyst yamabhodlela amanzi epulasitiki izobola ibe emanzini okuqukethwe.Lapho isikhathi sokugcinwa kwamabhodlela amanzi epulasitiki siba side, i-antimony iyanda, kanye nemvula ye-antimony phakathi nonyaka.Inani lizophinda kabili, futhi ucwaningo luye lwabonisa ukuthi i-antimony iyingozi emzimbeni womuntu.
Ukusebenzisa i-polyester (PET) amanzi asebhodleleni, ngokuhamba kwesikhathi, kungabangela futhi i-carcinogens efana ne-DEHA (i-adipic acid diester noma ehunyushwe ngokuthi i-ethylhexylamine) ukuba idle.Ngakho-ke, i-US Food and Drug Administration (FDA) inqume ukuthi ukupakishwa kwengilazi kuphephile.)
Kumele kuqashelwe ukuthi ingilazi ye-soda-lime ayinamanzi, i-acid-resistant futhi i-alkali-resistant.Ngakho-ke, amabhodlela engilazi ye-soda-lime aqukethe izixazululo ze-alkali azoguguleka.Isibonelo, ezinye izinkampani zisebenzisa ingilazi ye-soda-lime njengebhodlela lomjovo we-sodium bicarbonate ukunciphisa izindleko.Akufanelekile ukukhiqiza ama-flakes, futhi ukupakishwa kwemithi kufanele kusebenzise ingilazi yezokwelapha efanelekayo ngokuhambisana namazinga kazwelonke noma imithetho ye-pharmacopoeia.
