Kuenzanisa kwe smc girazi fiber yakasimbiswa epurasitiki zvinhu uye simbi uye zvimwe zvinhu

Kuenzanisa kweSMC composite zvinhu uye simbi zvinhu:

1) Conductivity

Masimbi ese anofambisa, uye chimiro chemukati chebhokisi chakagadzirwa nesimbi chinofanira kuvharirwa, uye imwe chinhambwe chinofanira kusiiwa sebhandi rekuzviparadzanisa nevamwe pakugadzwa kwebhokisi.Pane imwe leakage yakavanzwa njodzi uye kutambisa nzvimbo.

SMC ipurasitiki ye thermosetting ine kupikisa kwepamusoro kupfuura 1012Ω.Icho chinhu chinodzivirira.Iyo ine yakakwira-inoshanda insulation resistance uye breakdown voltage, iyo inogona kudzivirira tsaona yekuvuza, kuchengetedza yakanaka dielectric zvivakwa pama frequency akakwira, uye hairatidze kana kuvhara.Kupararira kwema microwave kunogona kudzivirira kuvhunduka kwemagetsi kwebhokisi, uye chengetedzo yakakwira.

2) Chitarisiko

Nekuda kwekugadzirisa kwakaoma kwesimbi, kutaridzika kwepamusoro kuri nyore.Kana iwe uchida kugadzira mamwe maumbirwo akanaka, mutengo uchawedzerwa zvakanyanya.

SMC iri nyore kugadzira.Inoumbwa nesimbi mold pasi pekushisa kwepamusoro uye kudzvinyirira kukuru, saka chimiro chinogona kuva chakasiyana.Iyo yepamusoro yebhokisi yakagadzirwa nedhaimondi-yakaita protrusions, uye iyo SMC inogona kuve yakapendwa pasina.Mavara akasiyana-siyana anogona kugadzirwa maererano nezvinodiwa nevatengi.

3) Kurema

Iwo chaiwo simba resimbi rinowanzoita 6-8g/cm3 uye iwo chaiwo giravhiti reSMC zvinhu kazhinji haapfuure 2 g/cm3.Huremu hwakaderera hunowedzera kufambisira mberi, zvichiita kuti kuisirwa kuve nyore uye nyore, uye kuchengetedza zvakanyanya mari yekufambisa uye yekuisa.

4) Corrosion resistance

Bhokisi resimbi harimirire kune acid uye alkali corrosion, uye iri nyore kuita ngura uye kukuvadza: kana ikabatwa nependi inorwisa-ngura, kutanga, ichava nekukanganisa kwezvakatipoteredza panguva yekupenda, uye itsva. Anti-ngura pendi inofanira kutorwa ose 2 makore.Mhedzisiro yehutu-hupupuriro inogona kuwanikwa chete nekurapa, iyo inowedzera zvakanyanya mari yemashure ekugadzirisa, uye zvakare yakaoma kushanda.

Zvigadzirwa zveSMC zvine corrosion resistance uye zvinokwanisa kuramba kukora kwemvura, peturu, doro, electrolytic munyu, acetic acid, hydrochloric acid, sodium-potassium compounds, weti, asphalt, akasiyana asidhi nevhu, uye mvura ine acid.Chigadzirwa chacho pachacho hachina kunaka kwekurwisa kukwegura.Pamusoro pechigadzirwa chine chidziviriro chekudzivirira nekudzivirira kwakasimba kweUV.Kudzivirirwa kwakapetwa kaviri kunoita kuti chigadzirwa chive nepamusoro-soro yekudzivirira kuchembera kuita: inokodzera marudzi ese emamiriro ekunze akaipa, mumhoteredzo ye -50C—+150 madhigirii Celsius, Inogona kuramba ichichengetedza zvinhu zvakanaka zvemuviri uye zvemuchina, uye nhanho yekudzivirira iIP54.Chigadzirwa chacho chine hupenyu hurefu hwebasa uye hachina kugadzirisa.

SMC yakaenzaniswa nemamwe thermoplastics:

1) Kuramba kukwegura

Thermoplastics ine yakaderera kuchembera kuramba.Kana yakashandiswa kunze kwenguva yakareba, tauro rinozoratidzwa kuchiedza uye kunaya, uye pamusoro pacho pachachinja nyore ruvara uye kusviba, kutsemuka uye kuve brittle, zvichikanganisa kusimba uye kutaridzika kwechigadzirwa.

SMC ipurasitiki ye thermosetting, isinganyungudika uye isinganyunguriki mushure mekurapa, uye ine yakanaka corrosion resistance.Inogona kuchengetedza simba rakakwirira uye kutaridzika kwakanaka mushure mekushandisa kwenguva refu kunze.

2) Kukambaira

Thermoplastics zvese zvine zvinokambaira.Pasi pekuita kwesimba rekunze kwenguva refu kana simba rekuzviongorora, imwe chiyero che deformation ichaitika, uye chigadzirwa chakapedzwa hachigone kushandiswa kwenguva yakareba.Mushure memakore 3-5, inofanira kuchinjwa seyese, zvichiita kuti pave nemarara akawanda.

SMC ndeye thermosetting material, isina chinokambaira, uye inogona kuchengetedza mamiriro ayo epakutanga pasina deformation mushure mekushandisa kwenguva refu.General SMC zvigadzirwa zvinogona kushandiswa kweanenge makore gumi.

3) Kuomarara

Zvigadzirwa zveThermoplastic zvine kusimba kwepamusoro asi kusagadzikana kusimba, uye zvinongokodzera zvidiki, zvisingatakure zvigadzirwa, kwete zvezvirefu, zvakakura uye zvakakura zvigadzirwa.
