Parizvino, kune akawanda epurasitiki, girazi uye silicone mukaka mabhodhoro pamusika.
Bhodhoro repurasitiki
Iyo ine mabhenefiti ehuremu huremu, kudonha kuramba uye yakakwirira tembiricha kuramba, uye ndicho chikuru chigadzirwa pamusika.Nekudaro, nekuda kwekushandiswa kwe antioxidants, colorants, plasticizers uye zvimwe zvinowedzera mukugadzirwa kwekugadzira, zviri nyore kukonzera kuparara kwezvinhu zvinokuvadza kana kutonga kwekugadzira kusina kunaka.Parizvino, zvinhu zvinoshandiswa mumabhodhoro emukaka epurasitiki ndePPSU (polyphenylsulfone), PP (polypropylene), PES (polyether sulfone), nezvimwewo. Zvinofanira kuonekwa kuti kune rudzi rwePC (polycarbonate) zvinhu, izvo zvaiwanzove zvakanyanya inoshandiswa mukugadzira mabhodhoro emukaka epurasitiki, asi mabhodhoro emukaka anogadzirwa nechinhu ichi anowanzo aine bisphenol A. Bisphenol A, zita resainzi 2,2-bis (4-hydroxyphenyl) propane, rakapfupikiswa seBPA, imhando yehomoni yezvakatipoteredza, izvo zvinogona kukanganisa metabolic maitiro emuviri wemunhu, kukonzeresa kukurumidza kuyaruka, uye kukanganisa kukura kwevacheche uye kusadzivirirwa.
Mabhodhoro egirazi
Kujeka kwepamusoro, nyore kuchenesa, asi kune ngozi yehutete, saka inonyanya kukodzera kuti vabereki vashandise pakudyisa vana vavo kumba.Bhodhoro rinofanirwa kusangana nezvinodiwa zveGB 4806.5-2016 yenyika kuchengetedza chikafu chiyero chegirazi zvigadzirwa.
Silicone mukaka bhodhoro
Mumakore achangopfuura akakurumbira zvishoma nezvishoma, kunyanya nekuda kwekunyorova, kunzwa kumwana seganda raamai.Asi mutengo wacho wakakwira, yakaderera silica gel ichava nekunakirwa, inoda kuve nehanya.Iyo silicone yemukaka bhodhoro inosangana nezvinodiwa zveGB 4806.11-2016 yenyika kuchengetedza chikafu chakajairwa rubber zvinhu uye zvigadzirwa zvekusangana kwechikafu.
