Chii chinonzi polyimide firimu

Firimu rePolyimide chinhu chinoshanda, kune nzvimbo dzakawanda kwarinogona kushandiswa, asi kune vatengi uye shamwari dzinoda kutenga, isu tinofanira kutanga tafunga kuti firimu repolyimide rine zvipi. Pano, isu Ngatitarisei sumo iri pazasi zvakadzama.

Polyimide firimu

Firimu rePolyimide rinoshandiswa zvakanyanya mumagetsi ekudhonza, submersible motors, midziyo yemagetsi enyukireya, waya-yepamusoro-tembiricha uye tambo, waya dzemagetsi, midziyo yemagetsi yakakosha, madhiri ebhasi, masks egasi, yakakwirira-tembiricha yakadhindwa yakadhindwa yedunhu substrates, flat-panel circuits, uye. mutauri inzwi coil mafuremu, etc. munda. Ndiyo yega isina-warping polyimide firimu rinoshandiswa kucheka kufa muChina. Thermosetting polyimide ine yakanakisa kugadzikana kwekupisa, makemikari kuramba uye michina zvimiro, uye kazhinji ndeyeorenji. Simba rekushanduka-shanduka uye flexural modulus yegraphite kana girazi fiber reinforced polyimide inogona kusvika 345 MPa uye 20 MPa, zvichiteerana. Thermosetting polyimide ine yakaderera inokambaira uye yakanyanya kusimba simba. Iyo tembiricha yekushandisa ye polyimide yakakura kwazvo, kubva paminus 100 degrees kusvika maviri kana matatu Baidu. Polyimide yakagadzikana mumakemikari.

Polyimide inogona kusapisa moto pasina kudzora murazvo. Maporiyidhi akajairika anoshingirira kumakemikari anonyungudutsa, akadai semahydrocarbon, esters, ethers, alcohols uye chlorofluorocarbons. Izvo zvakare zvinopesana neasina simba acids, asi hazvikurudzirwe kushandiswa munzvimbo yakasimba alkali uye inorganic acid. Mamwe ma polyimides, akadai seCP1 uye CORINXLS, anonyungudika muzvinonyungudutsa, izvo zvinobatsira kuvandudza maapplication avo mukupfapfaidza-kupisa uye kuyambuka-kubatanidza.
