Kudziwika kwa ufa wa PVB
1.Kukhazikitsa kuwonekera poyera ndi chifunga
Malangizo ogwirira ntchito: Choyamba, tsambulani pamwamba pagalasi ndi ethanol kuti muwonetsetse kuti galasi ndi loyera. Ikani nkhungu yamagalasi ya PMMA pachitsanzo cha galasi, onjezerani utomoni mu poyambira ndikosalala ndi ndodo yagalasi, chotsani nkhungu, ndikuphimba chidutswa china chagalasi, ndikusamutsira makina opukutira kuti muthe kukanikiza. Choyamba, konzekerani pa 0MPa ndi 125 ℃ kwa mphindi 3 ~ 4, kenako ndikulumikiza pa 0.25MPa, zomwe zimatenga mphindi 5 ~ 6, zomwe ndi kukanikiza kotentha kumamalizidwa. Kukula kwa galasi limodzi ndi makulidwe athunthu a galasi laminated adayezedwa ndi vernier caliper, makulidwe a galasi laminated akuyerekezedwa (pafupifupi 0.76mm), mawonekedwe amiyala inayi yoyang'ana magalasi ophatikizidwa adayesedwa ndikuwerengedwa, komanso makulidwe a galasi laminated adagawika kuti akhale ndi gawo. Nthawi yomweyo, chidutswa cha galasi lokutira kapena galasi laminated liyenera kukhala lokonzekera ngati gulu lolamulira lopanda kanthu kuti lithetse cholakwikacho.
2.Butyl okhutira
Malangizo Ogwira Ntchito: Sungunulani utomoni wa ufa wosakanikirana ndi ethanol solvent poyamba, kenako onjezani yankho la hydroxylamine hydrochloride, kusonkhezera wogawana kenako kutentha Reflux mu madzi osambira a 2.5h kuti yankho mu botolo la conical limveke bwino. Kuchokera pamwamba pa chubu lolowetsa, onjezerani madzi 50ml kuti muyeretsedwe, tulutsani botolo lokhazikika ndikuzizira kutentha, kenako onjezerani 3 ~ 4 madontho a 0.1% bromophenol buluu chizindikiro, titrate kusalowererapo ndi yankho la 0.1mol / L NaOH , yerekezerani ndi gulu lopanda kanthu, ndipo konzani kuwerengera zinthu za butyl.
