Polyphenylene Sulfide yakakurumbira zvinhu muinjiniya mapurasitiki

Mukati mezvinhu zvakawanda zvakakurumbira zveinjiniya mapurasitiki, chimwe chinhu chinozivikanwa zvakanyanya ndeye polyphenylene sulfide (PPS).

Waizviziva here kuti mapurasitendi engine ari pasi pekugara-nguva yekunzwa uye yemakemikari uye enystem nharaunda? Mapuranga enyama anofanirwa kutsungirira zvine musoro kushushikana kwenguva yakareba, asiwo anofanira kutsungirira nharembozha uye zvepanyama, uye polpenylene sulfide mune izvi zvakanaka mune izvi.

Izvo zvine zvimiro zvirinani, zvimiro zvemagetsi, kupokana kwemakemikari, kupisa kupesana, kupokana nekumisikidza nekugadzikana kwemapurasitiki pane general plastics. Kiyi ndeyekuti yakareruka kupfuura simbi yekugadzirwa, kushandiswa kwesimbi kune zvidiki zvidiki, saka zvinoshandiswa zvakanyanya mumagetsi, kuvaka, kuvaka, kumachinji, michina uye mamwe minda yakawanda.

Kupisa kupokana kuri nani, kunyungudika pfungwa kunogona kusvika 275 - 291 ℃, kupisa kukanganisa kwekupisa kwe135, girazi fiber yakasimbisa kupisa tembiricha kusvika ku20 Mumhepo uye nitrogen, tembiricha yekutanga yekushomeka kwe400 ° C, 700 ° C mukuora kwemhepo, 1000 ° C inert inogona kuchiri kuchengeta 40% yehuremu. Nguva refu kushandisa tembiricha 200 - 240 ℃, gasi chipingamupinyi chinopesana uye kwenguva refu-nguva yekuenderera mberi yekusagadzikana kwekunyora pane ese engineering purastics.

Zvivakwa zvemuchina, zvakanyanyisa kuomarara, asi zvinowedzera kusimbisa zvinonyadzisira, kwete kuramba benzene, peturu uye mamwe organic sol. Nekudaro, mushure mekuwedzera girazi fiber kana kumwe kusimbisa zvinhu zvakashandurwa, kukanganisa simba, zvakakodzera kugadzirwa kwenhengo dzekupisa, dzinosimbisa nzvimbo, zviridzwa zvemakemikari, zviridzwa zvemagetsi uye zvimwe zviridzwa.

Nekuda kweiyo yakagadzikana yemakemikari yemakemikari uye sarufa yezvinyorwa, polyphenylene zvinodiwa. Kwete izvozvo chete, kupokana kwayo kwakanyanyisa kunakidza kwazvo, kuwedzera kune yakasimba oxdizizization acid, alkalis uye yemumunziridzi corros iri pedyo nePTFE, asiwo mamiriro ekunze uye radiation kuramba.

Zvivakwa zvemagetsi zvakare zvakanakisa, kupisa kwakanyanya uye nekushomeka kwehuwandu, iyo Dilelectric yekuchinja, yakaderera dielectric zvivakwa zvezvigadzirwa zvemagetsi zvinoda kwazvo .

Kuita kwayo kwekuita kwakanaka, kuderera melt viscossity, flong yakanaka, nyore kutaurirana negirazi fiber, ichizadza uye kusungwa kwakanakira girazi, aluminium, simbi, isina simbi uye zvimwe zvigadzirwa. Kugadzikana kwakasiyana-siyana, mvura yakaderera uye mafuta ekunyura, kuumbwa kwemutsara

Uye tarisa maapplication yayo, ayo akanyatso-tsika.

Mumunda wezvematare emagetsi, zvinogona kutsiva mitezo uye iyo esermosetting engineins yeinjini

Mune zvivakwa zvekugara uye zvigadzirwa zvekunyepedzera, zvakadai seanotengesa mvura, zviwanikwa zvine mvura, uye zvinhu zvepamhepo, zvimedu zvemvura zvakadzama nekuda kwehunhu hwekupesana nemvura inopisa, kumanikidza kuramba, uye kuoma.

Muzvikamu zvemagetsi / zvinowanzoshandiswa muzvikamu zvemagetsi / zvemagetsi zvevanobatanidza, uye zvakanyanyisa kupokana, kudzikisira, uye kupfumisa kupfupika kudzoreredza kunoita kuti ive yakanaka yekuumbwa.

Mundima yemichina indasitiri uye yekemical indasitiri, mineral filer, manyura filer kana carbon fiber kuti aumbe midziyo yekugadzira, iyo inogadzira michina yezvikamu uye zvigadzirwa zvemakemikari.

Mumunda wemabhandi eLithium, kupokana kwayo kupisa, kusimbisa uye zvemagetsi zvivakwa zvinoita kuti iite hit.

Mundima yekudzivirirwa kwezvakatipoteredza, pps fiber zvigadzirwa zvine chekuita negasi gasi uye gurusivation kurwisa zvinhu zvinogona kuvandudza hupenyu hwekubvisa kweruva, mune masimbi madiki, incinerators, incinerators, magetsi ekudziya emagetsi uye dzimwe nharaunda dzinotamba chinzvimbo chakakosha.

Tevere, ngatienzanise Polyphenylene Sulfide (PPS) neimwe nzira yepamusoro-perinjiniya yepurasitiki, peek.

Panyaya yekupisa kupisa, peek ine tembiricha yebasa refu ye260 c, iyo yakakwirira zvishoma kupfuura pps. Nekudaro, polyphenylene sulfide ine hukama hwehukama maererano nemutengo.

Panyaya yezvivakwa zvemuchina, iyo simba uye kuomarara kwezvinhu zvinowanzo kuve nani pane iyo yePolyphenylene Sulfide inogona kushandurwa kuti igadziriswe zvido zvezvakawanda zvekushandisa zvekushandisa.

Panyaya yekugadzirisa performance, polyphenylene sulfide ine yakadzika melt viscossity, iri nani fluiliity, uye iri nyore kuita uye kuumbwa.

Kubva pamaonero emutengo, pps kazhinji inokwanisika kupfuura peek, ichiita kuti inyunzi yakakurumbira kune inodhura-inonyadzisa.

Polyphenylene Sulfide uye peek imwe neimwe ine zvavakanakira, uye sarudzo yechinhu chakananga zvinoenderana nezvinodiwa zvekushandisa uye zvinodhura.

Polyphenylene Sulfide (PPS) ipurasitiki yeinjiniya inopfuura inodarika munzvimbo dzakasiyana siyana. Sechimiro chekuumba, chinogona kutsiva simbi uye nekuporesa-kuporesa-kupisa kwemakemikari, zvinovandudza mari, uye maitiro ayo mazhinji akanaka anoita kuti iwanikwe muminda dzakasiyana siyana uye kuunza mabhenefiti akawanda kune maindasitiri ane hukama.
