Ndeupi musiyano uripo pakati pepeek uye pps?

PPS (Polyphenylene Sulfide) Papurasitiki inozivikanwa yeinjiniya ine mvura yakaderera, kupfeka kurwisa, kudzikisira kwakakura, kupfupika kwemweya, kusimbisa kwemagetsi, uye kupisa kwemagetsi. High humidity inogona kuramba ichiramba yakanaka yemagetsi zvemagetsi. Kunyepa kwakanaka, zviri nyore kuumba, kanenge pasina shrinkage makomba kana uchiumba. Uye ine hukama hwakanaka nevakasiyana-siyana malericlers. Iyo inoshandiswa zvakanyanya nekuda kwekuita kwayo kwakanaka, kunyanya yakakodzera kune inokanganisa uye inosimbisa nzvimbo.

Peek (polyether ether etone) ndeyekunyatsojeka engineering zvivakwa, kupesana nekupokana, kupokana kwemakemikari, etcompany inodzora zvivakwa, Zvinotaurwa, uye kugadzira zvakakwirira-zvinodiwa michina senge magiya, fani, zvigaro zvevharanda, zvindori, pombi inopfeka zvindori, uye ma gasi.

Saka chii chinonzi musiyano mukuru pakati pePPs uye zvigadzirwa zvega?

1. Panyaya yekushisa kurwisa, peek ine tembiricha yenguva refu ye250 ° C, tembiricha yegumi neimwe yegumi neimwe ye300 c, uye kanenge isina kuora pa400 ° C munguva pfupi; PPS inogona kushandiswa pa 220 ° C kwenguva yakareba, uye inogona kusvika 260 ° C munguva pfupi yenguva. Inline Pfungwa: pps iri pa 280 ° C, peek iri pa120 ° C, uye peek inogona kuchengetedza yakakwirira michina uye yemuchina simba kunyange pakupisa kwakanyanya.

2 Panyaya yeiyo tensile simba, PPS ndeye 105mpa, nepo peek is 115mpa. Muzhinji, peek yakakwirira kune pps fiber yakasimbiswa zvigadzirwa maererano neine tensile Simba PPS yakaoma kutsiva kana chete peek inowanikwa, kunyanya pakupisa kwakanyanya.

3. Panyaya yemubhadharo, kunyangwe pps yakaoma kutsiva peek maererano nekuita, mutsipa mutsauko pakati pezviviri kakawanda, uye kushandiswa kwePP PPS kunogona kuderedza zvakanyanya mutengo. Kana kuita kwePeek kwanyanya mune mamwe mamiriro ekushanda kana mune dzimwe nguva dzakashata kana tembiricha yakaderera, pps inogona kushandiswa pachinzvimbo.

Muzviremekedzo zvakawanda, zvakaoma kuenzanisa PPS ne peek, nekuti peek iri mushure mekirasi yose yepamusoro yekirasi yepamusoro pomubati. Zvivakwa zvishoma zvekunyama zvinozvibata zvakafanana, zvakadai semurazvo wekurwisa, magetsi ekusimbisa kwesimbe uye dielectric zvivakwa.
Kunyanya maererano nezvinhu zvekupisa uye zvekuita, kuenzanisa pakati pePPs vs peek zvakajeka favoek. Kunyangwe pps inopa simba repamusoro rekumanikidza kuenzaniswa neeek (pa5% peek = 102 mpa vs. pps = 134 mpa). Peek ine yakakwira jactility (elongation ku break peek = 15% vs. pps = 6.5%). Izvi zvinoguma zvakakwira zvakanyanya Simba (peek = 166 mpa vs. pps = 103 MPA) uye yakakwira charpy simba (

Uye zvakare, iyo yakadzika duku yePPs ichienzaniswa neeek inokanganisa maitiro emununuru, iyo inoonekwa nekureba kweBurr yekugadzira uye mapfupi machipisi, asi njodzi yakakwira yekupaza.

Kune mamwe mashandisirwo, anoda michina yekunyorera kuti azive zvivakwa zvisina kufanira kana micro-maburi, pps anogona kutungamira kumhedzisiro iri nani pane peek.

Muzhinji, vese vane peek uye pps vane yakanaka kwazvo dimensional kugadzikana maererano nemitemo yemvura yekunyora uye kuwedzera kuwedzera. Mapps anoratidza zvishoma pasi mvura yekudzora mvura, nepo peek inoratidza zvishoma pasi zviyero zvekuwedzera kwekuwedzera kwekuwedzera. Ipo maPP yePPs akaderera kusvika pa100 ° C (ne6 * 10-5 / kombwe inowedzera steeply (kusvika 11 * 10-5 / k pa100 ~ 100 ° C) munzvimbo dziri pamusoro pegirazi tembiricha tembiricha.

Pamusoro pezvakanakira zvevhu zvine hukama hwakakwira, simba uye kupisa kwetembiricha zvichienzaniswa nePPs, imwe mukana wezvinhu zviri nani kupfeka kupokana. Iyo data iri pazasi inoratidza yekufananidza bvunzo bvunzo yemamp yemamp inochengeta mhete.

Izvo zvakanakira zvevhu pamusoro pePP zvinoratidzwa mumitengo yekufananidza - peek ichave sarudzo inodhura. Naizvozvo, pps mapurasitiki iri imwe nzira inonyanya kukosha kana zvinhu zvekunyama zvakanyatso pfuura zvinodiwa. Muzhinji, iyo yakaderera-mutengo pps imwe nzira ndeyekuti sarudzo iri nani.

Kuwedzera kune iyo yekupfuura-engineering chikamu, pps zvinhu zvine imwe nhanho yekusagadzikana: ine huwandu hwakawanda hwekudzora kwemakemikari pane peek - chete ptfe inogona kupfuura iyo mune izvi mune izvi.
