Chii chakapfeka-chinodzivirira chipurasitiki

Pfekisiki yekupfeka ndeyemhando yerudzi rwePolymer, inogona kutsungirira kupfeka kwenguva refu, inogona kupfeka zvisina kufanira kwekupfeka, kazhinji inoshandiswa muchimiro chemuchina uye michina inoda kutsungirira kupfeka uye kukwezva kwakanyanya.

Parizvino yakanyanya kupfeka kurwisa kana nyanzvi yeinjiniya mapurasitiki pi Pai peek zvinyorwa, kuwedzera kune vezera remakore nekuda kwekudzikiswa zvishoma nezvishoma mumutengo, zvimwe zviviri zvigadzirwa zvinodhura uye zvakaoma kushandisa pachiyero chakakura. Kechipiri, kupfeka kupfeka kuita kuri nani engineering purastics nylon pa12, pa11, pa66, pa66, pom, etc., ichiteverwa ne pe pet, nezvimwe.

Iyo inonyanya kushandiswa kuteedzana kweinjiniya yepurasitiki pa66 uye pom nylon uye pom zvinowanzoshandisirwa mapurasitiki ekunyepedzera imwe inonyanya kupfeka. Nekudaro, kubva mukushisa basa re nylon shandisa huwandu hwakawandisa, kunyanya kuburikidza nekugadziridzwa kweiyo nylon yekuwedzera shen semuenzaniso kupfuura ingon 66 Pfeka modhi 66 Pfeka modhi ine mazana emamwe marudzi akawanda. Isu magadzirirwo ezvigadzirwa kusarudza zvinhu kubva pane chaiyo yekushanda mamiriro anodiwa: Chigadzirwa chimiro, tembiricha, mutoro, kumhanyisa, hupenyu, hupenyu uye zvichingodaro kuwana chirongwa chakakodzera. Chairo sarudzo yeNylon kana pom inonongedza kurudziro yefekitori yakagadziridzwa, kuitira kuti chigadzirwa chacho chine chekuita nekubhadhara zvakanakira.

Nylon compound shanduko nekuwedzera mumiririri wekupfeka zvinowanzo shandiswa Inotsvedza kunzwa, kusakwana mumvura, chigadzirwa chine kugoverwa kwakanaka, zvakanakira kusungwa kwesiri-kusungwa kwakanyatsokwanirisa kune yakakwirira-tembiricha neyekumanikidza.

PTFE, anozivikanwawo seTeflon inozivikanwa se "mambo wepurasitiki" is tetrafluorohlene seye monmerination yePolymer, kudzikisira, inogona kushandiswa kwenguva yakareba yenguva in -180 º c. Izvi zvinyorwa zvine acid naAlkali kuramba, uye zvinogona kushandiswa kwenguva yakareba. Izvi zvinyorwa zvinoratidzwa nekupokana neAcids, alkalis uye organic sol sol solvent, uye ingangoita zvisikwa mune ese miganhu. Panguva imwecheteyo, PTFE inoonekwa nekudziya kwakanyanya kwekushisa uye ine yakanyanya kuderera kuwirirana.

Iyo yakanyanya kupfeka-inodzivirira plastiki

Peji yepurasitiki ndeyekisimusi yakakwirira-purasitiki, ine hutsinye simba simba, kupisa kwemakemikari uye nekumisikidza-kupfekedzwa kuita zvimwe zvinowanzoitika zvekupfeka hazvigone kufananidzwa. Mukukakavara kukuru, mutoro mukuru uye wepamusoro-soro mamiriro, Peji yepurasitiki inochengetedza zvakanaka kupfeka uye kugadzikana kwekuita, parizvino pane mhuka dzinopfekedza mapurasitiki pamusika.

Zvakanakira uye zvakashata zvePapurastic

1. Zvakanakirwa: Yakakwirira Mechan Simba, Yakanakisa kupisa kupokana, kusimba kwakanaka kwemakemikari, zvakanakisa kuramba, zvinhu zvakanaka zvekusimbisa, kugadzirisa zviri nyore, kuumbwa.

2. Zvakaipa: Yakakwira mutengo, brittle, isinganyatsochinja.

PI application nzvimbo

Pai plastics inoshandiswa zvakanyanya muEerospace, mainjini ekushandisa, zvigadzirwa zvemagetsi, zvakadai, mapepa, zvisimbiso uye zvimwe zvikamu uye zvimwe zvinhu zvinoda kupfeka zvakanyanya uye simba rakanyanya.

Peji yepurasitiki ndiyo yakanyanya kupfekedza mapurasitiki pamusika nhasi, aine simba rekupisa simba, kusimba kwemakemikari akanaka, kupfeka, kuumbwa, etc., asi mutengo wakakwira, but. zvinoshanduka. Inoshandiswa zvakanyanya muEerospace, emagetsi, zvemagetsi, zvishandiso zvemagetsi uye mimwe minda inoda kutsungirira pakapfeka zvakanyanya uye zvikamu zvakakwira.
