I-20G umgangatho ophezulu wokuphunyezwa kwetyhubhu yebhoyiliGB5310-2008Umda wesicelo, usetyenziselwa ukuvelisa uxinzelelo oluphezulu kunye noxinzelelo olungaphezulu koxinzelelo lwamanzi kwibhoyila yokufudumeza indawo enomgangatho ophezulu wekhabhoni yentsimbi, intsimbi yealloyi kunye nentsimbi engenamthungo yentsimbi. Uxinzelelo oluphezulu lwebhoyili ityhubhu yensimbi luhlobo lwetyhubhu yebhoyila, kuba i-20G ityhubhu yebhoyila yoxinzelelo oluphezulu ihlala isetyenziselwa ubushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu, ityhubhu ephantsi kwesenzo sobushushu obuphezulu begesi kunye nomphunga wamanzi, i-oxidation kunye ne-corrosion iya kwenzeka. Umbhobho wensimbi ufuneka ukuba ube namandla ahlala ixesha elide, ukuxhatshazwa kwe-corrosion ephezulu ye-oxidation kunye nokuzinza okulungileyo kwe-microstructure. Ityhubhu yebhoyila yoxinzelelo oluphezulu isetyenziselwa ukwenza uxinzelelo oluphezulu kunye ityhubhu yebhoyila yoxinzelelo lwe-ultra-high, ityhubhu yokufudumeza, umbhobho, ityhubhu yebhoyila engundoqo, njl. njl Iqamza, uxinzelelo akufuneki ludlule uxinzelelo lwebhoyila, abasebenzi bebhoyila kufuneka basoloko bejonga igeyiji yoxinzelelo lomphunga. Xa umbhobho webhoyili ugcwele amanzi, kufuneka ukhutshwe ngexesha lokumisa i-co-hydrating kunye nokubuyisela umgangatho wamanzi. Emva kokuba isithando somlilo simisiwe, emva kokuba amanzi epholile ixesha elide ukuya ngaphantsi kwama-degrees angama-70, amanzi omlilo anokukhutshwa, kwaye ke ibhoyili yokucoca imichiza yamanzi engase ingasetyenziswa emva kokuba umnatha ukhutshwe. Ibhoyila yoxinzelelo oluphezulu ityhubhu yensimbi engenamthungo isetyenziswa ikakhulu ukwenza uxinzelelo oluphezulu kunye ityhubhu yebhoyila yoxinzelelo oluphezulu, ityhubhu yokufudumeza, umbhobho, umbhobho webhoyila ongundoqo, njl. njl. ityhubhu yebhoyila.
