Graphite inoshandiswa zvakanyanya mukugadzira michina yemakemikari nekuda kweiyo yakanakisa corrosion kuramba, magetsi conductivity, uye kugadzikana kwekupisa. Nekudaro, graphite inoratidza isina kusimba mekiniki zvivakwa, kunyanya pasi pesimba uye vibration mamiriro.Girazi fiber, sechinhu chepamusoro-chekuita chinoumba zvinhu, chinopa zvakakosha zvakakosha pazvinoshandiswa kune graphite-based chemical equipment nekuda kwekupisa kwayo kupisa, kudzivisa kuparara, uye hukuru hwemagetsi. Zvakanakira zvinosanganisira:
(1) Kuvandudza Mechanical Performance
Simba rekusimba regirazi fiber rinogona kusvika 3,450 MPa, inodarika iyo yegraphite, iyo inowanzobva pagumi kusvika makumi maviri MPa. Nekusanganisa girazi fiber mune zvigadzirwa zvegraphite, iyo yese mechanic kuita kwemidziyo inogona kuvandudzwa zvakanyanya, kusanganisira kuramba kukanganiswa uye kudedera.
(2) Corrosion Resistance
Girazi faibha inoratidza kuramba kwakanyanya kune akawanda asidhi, alkalis, uye zvinonyungudutsa. Nepo graphite pachayo ichinyanya kusaora,girazi fiberinogona kupa kushanda kwepamusoro munzvimbo dzakanyanyisa dzemakemikari, dzakadai sepamusoro-tembiricha uye high-pressure mamiriro, oxidizing atmospheres, kana hydrofluoric acid nharaunda.
(3) Kuvandudza Thermal Properties
Girazi faibha ine yakanyanya kuderera coefficient yekuwedzera kwekupisa (CTE) inosvika 5.0 × 10−7/°C, kuve nechokwadi kugadzikana kwedimensional pasi pekunetseka kwekupisa. Pamusoro pezvo, nzvimbo yayo yakakwira yekunyungudika (1,400-1,600 ° C) inopa yakasarudzika yekupisa tembiricha. Aya maitiro anogonesa girazi fiber-reinforced graphite zvishandiso kuti zvichengetedze kutendeseka kwechimiro uye kushanda munzvimbo dzinopisa zvakanyanya uye zvishoma deformation.
(4) Uremu Zvakanakira
Nehuremu hunosvika 2.5 g/cm3, faibha yegirazi inorema zvishoma pane graphite (2.1–2.3g/cm3) asi yakareruka kupfuura zvinhu zvesimbi sesimbi kana aruminiyamu. Kubatanidza girazi faibha mumidziyo yegraphite kunokwidziridza mashandiro pasina kuwedzera huremu, kuchengetedza huremu hwemidziyo uye inotakurika.
(5) Kushanda Kwemari
Kuenzaniswa nemamwe macomposites akakwira-performance (semuenzaniso, kabhoni fiber), girazi fiber inodhura-inoshanda, ichiita kuti ive yakakosha kune makuru-akawanda maindasitiri ekushandisa:
Raw Material Mari:Girazi fiberinonyanya kushandisa girazi rine mutengo wakaderera, nepo kabhoni fiber ichitsamira pane inodhura acrylonitrile.
Manufacturing Costs: Zvese zviri zviviri zvinhu zvinoda kudziya kwepamusoro-tembiricha uye yakakwirira-kumanikidza kugadzirisa, asi kabhoni fiber kugadzirwa kunosanganisira mamwe matanho akaomarara (semuenzaniso, polymerization, oxidation kudzikamisa, carbonization), kutyaira kukwira.
Kudzokorodza uye Kurasa: Carbon fiber inonetsa kudzokorodza uye inoisa njodzi kwezvakatipoteredza kana ikasabatwa nemazvo, zvichikonzera kukwira kwemitengo yekurasa. Girazi fiber, mukusiyana, inogoneka uye eco-inoshamwaridzika mumagumo-e-hupenyu mamiriro.
