Maitiro ekuwedzera kuramba kukwenya kwepurasitiki uye kuramba kukwenya

Sarudza resin chaiyo yakakodzera

Kazhinji polyethylene ine huremu hwakawanda (PE-UHWM) ndeimwe yemapurasitiki anodzivirira kupera, uye kusarudza PE-U·HWM kunogona kungovandudza kuramba kupera kwezvinhu. Pamusoro pezvo, mapurasitiki ane crystallization yakawanda, kugara kwenguva refu anodzivirira kupera kupfuura ane kuomarara kwakanyanya. Mukugadzirisa polypropylene (PP), #muchina wekuisa pelletizing wepp polyolefin elastomer (POE), ethylene propylene terene rabha (EPDM), thermoplastic dynamic vulcanized rabha (TPV) (yakadai se dynamic vulcanized PP/EPDM) inowanzo shandiswa kusimbisa PP, uye kuwedzerwa kwe elastomers kunowanzo tungamira kudzikira kwekudzivirira kukwenya, saka zvakakosha zvikuru kusarudza elastomer yakakodzera. Kurongeka kwekudzivirira kukwenya ndekwekuti: TPV > EPDM > POE. Muchina wekugadzira magranules e #pp.

Shandisa chizoro chinodzivisa kupfekwa zvakanaka

(1) Molybdenum disulfide

Molybdenum disulfide, chinhu chinodzivirira kupera, chinonyanya kushandiswa mumapurasitiki enylon. Molybdenum disulfide inoshanda sechinhu chinodzivirira kupera kuwedzera kristaro yenylon, saka chinhu chenylon chinoita kuti nzvimbo yacho ive yakaoma uye isingatsvedze. Molybdenum disulfide ine simba guru resimbi, kana yangonamirwa pamusoro pesimbi, mamorekuru emolybdenum disulfide anozadza pamusoro pesimbi nemaburi madiki, uye anoita kuti pamusoro pesimbi pave panyoro, izvo zvinoita kuti molybdenum disulfide ive chinhu chakanakira chinodzivirira kupera panguva dzekukweshana kwenylon nesimbi.

(2) Girafiti

Maumbirwo egraphite ndiwo maumbirwo ekristaro emineral graphite, hexagonal layer, maumbirwo aya akasiyana emakemikari anoita kuti mamorekuru egraphite atsvedzere zviri nyore kana paine kukweshana kushoma, kuramba uku kusakara kwakakosha zvikuru munharaunda ine mvura, saka graphite sechinhu chinodzivirira kusakara chinoshandiswa munzvimbo dzakawanda dzakaiswa mumvura, dzakadai seganda remvura, banga uye chisimbiso. #muchina wekuvaka wepp template board #muchina wekugadzira pepa une furo wexpe

(3) Girazi reFiber

Fiber yegirazi inogona kuumba chisungo chakasimba chemuchina pakati pemapolymer, saka fiber yegirazi inogona kuvandudza kusimba kwezvimiro zvethermoplastic uye kuvandudza kuramba kupfeka. Fiber yegirazi inopa simba uye inogona kuvandudza kufambiswa kwekupisa uye kuchinja kwekupisa kwemapurasitiki, zvichivandudza zvakanyanya kuramba mutoro uye kuramba kupfeka kwemapurasitiki.

(4) kabhoni faibha

#Muchina weCFRTP Composite

Kufanana negirazi fiber, kabhoni fiber inogona kuvandudza zvikuru kusimba kwechimiro chezvinhu, kuramba mutoro uye kuramba kupfeka. Kusiyana negirazi fiber, kabhoni fiber ifiber yakapfava uye isingakwenyeki zvakanyanya, uye kabhoni fiber haizokwenye pamusoro pekukweshana kwesimbi kana simbi iyo inokweshwa nayo.

Wedzera zvimwe zvinodzivirira kupfeka zvakakodzera

(1) Polytetrafluoroethylene (PTFE)

Polytetrafluoroethylene (PTFE) ine coefficient yakaderera yekukweshana, uye mamorekuru ePTFE anoumba firimu rinonyorovesa pamusoro pechikamu panguva yekukweshana. PTFE ine mafuta akanaka uye inodzivirira kukweshana kana yakakweshana, uye ndiyo additive yakanakisisa inodzivirira kukweshana kana yakakweshana. Aya mashandisirwo anosanganisira hydraulic piston ring seals uye thrust washers. PTFE yakawanda mumapurasitiki asina chimiro inowanzova 15%, uye mumapurasitiki ekristaro inowanzova 20%.
