Mavanga chigadzirwa chisingadzivisike chegadziriro yekugadzirisa ronda remunhu. Mavanga epamusoro haawanzo kuva nezviratidzo zvemuno, asi kuwanda kwakanyanya mavanga kunogona kukonzera kuchenesa kwenzvimbo uye zvimwe zviratidzo, uye zvinogona zvakare kutungamira mukukanganisa kwehutano kana gomarara.
Mishonga yekurapa silicone yekupfeka zvigadzirwa zvakaiswa kumuviri wemunhu kweanopfuura makore makumi mashanu. Ivo vane hunhu hweasina-chepfu, asiri anotsamwisa, asiri-antigenic, asiri-carcinogenic uye teratogenic, uye yakanaka bio-inoenderana. Sezvo K Perkins nevamwe vakawana ngowani yesilicone gel ine simba rekudzora mavanga muna 1983, huwandu hwakawanda hwezvidzidzo hwakaratidza kuti zvigadzirwa zvesilicone zvinogona kudzivirira kukura kwechiuno.
Yedu silicone zvigadzirwa zvakakamurwa kuita silicone gel mafuta uye silicone gel chigamba. Pakati pavo, silicone gel chigamba chiri pachena, inonamira, yakaoma, uye inogona kushandiswa kakawanda. Iyo silicone gel chigamba ine yakanaka mweya inokwanisika, uye iyo mvura mhute yekuchinjisa mwero iri padyo nehafu yeiyo yeyakajairika ganda, iyo inogona kudzivirira ronda pamusoro kubva kune hunyoro kurasikirwa. Chengetedza ronda pamusoro peunyoro, zvinoenderana nekuvandudzwa kwemasero epithelial. Kuchena-kubvisa silicone membrane ine mvura volatilization maitiro pane mavanga. Hydration inobvumidza ganda kuti rirambe riine huwandu hwepamusoro hwemvura, uye inoshanda mvura volatilization inobatsira ganda kuchengetedza elasticity. Kuchengeta ganda rakanyorovera kudzivirira ganda kubva pakuoma uye kutsemuka, nokudaro richideredza zviratidzo zvekurwadziwa kweganda uye kuvava.
Zvimiro
isina-chepfu, isingatsamwisi, isiri-antigenic, isiri-carcinogenic, isiri-teratogenic, uye yakanaka bio-inoenderana.
