Chirevo chekuvanzika: Kuvanzika kwako kwakakosha kwazvo kwatiri
Mhedzisiro yeCrystallinity pane jekiseni yakaumbwa zvigadzirwa
PPS ndeye crystalline polymer, crystallinity inosiyana neyekutonhora tembiricha uye chiyero panguva yekuumbwa, uye iyo yakanyanya crystallinity inogona kusvika 85%. Izvo zvinyorwa zvine yakakodzera crystallinity inogona kusarudzwa zvichienderana neyemuchina madekisi anodikanwa nezvako.
* Mhedzisiro yeCrystallinity yakawedzera pane jekiseni zvigadzirwa zviri seinotevera: *
Zvikamu Zvakakanganiswa:
1) yakawedzera kupisa kupisa tembiricha
2) yakawedzera kuomarara
3) Simba remagetsi rakatetepa pamhepo tembiricha rakaderedzwa zvishoma, asi simba rakafanana nekudziya kwakanyanya kunowedzera,
4) Simba rakakotama riri pazasi 95 ℃ kuderera, uye kusimba kwekukotama pamusoro pe95 ℃ Kuwedzera
5) Simba rekukanganisika rakaderedzwa;
6) yakawedzera dimensional kugadzikana uye kudzikisira kupokana
7) Iyo yepasi pasi yeiyo jekiseni yakaumbwa zvigadzirwa zvinowedzera (asi kana iyo yepasi pasi ichinge yakaipa mushure mekuwedzera)
8) yakawedzera kuomarara kuomarara
9) Iyo inoderera chiyero chinowedzera, uye kugadzikana kwedanho pakugadzikana kwekushisa kwakanyanya kunovandudzwa
10) yakaderedzwa mutsara unowedzera kuwedzera kuwedzera

Maitiro ekuyerera
Sezvo tembiricha inowedzera, iyo nzira yePPS inoenderana zvakanyanya, asi kana tembiricha yakanyanya kana nguva yekugara yezvinyorwa zvakareba, izvo zvichaitika, zvichikonzera kuderera kwezvinhu.

Molding shrinkage
PPS Moling Shringer chiyero chinowedzera nekuwedzera kwekuumbwa kwemotokari. Kazhinji, kuderera kwePolyphenylene Sulfide idiki, asi iyo inoderera mufambiro wekutungamira wekuyerera ndeye 2 ~ ka4 times yakakura kupfuura kutungamira kwekuyerera. Uye zvakare, iyo chigadzirwa chakakora, chimiro, uye kuridza mhere zvakare kuchave nekukanganisa pamaoko okugadzira. Mumamiriro ezvinhu akajairwa, ukobvu hwechigadzirwa hunofanirwa kunge hwakafanana, uye madziro kumashure haafanire kupfuura 7 ~ 10mm. Zvikasadaro, poled-yakavakirwa polyphenylene sulfide kuumba zvigadzirwa zvinofanirwa kushandiswa.

Kugadzikana kweTermal
PPS ichave inopararira qualidation yekuyambuka-inobatanidza maitiro pakupisa kwakanyanya. Kana ikaramba iri mubhari kwenguva yakati rebei, ichaderedza iyo fluidity yezvinyorwa, rima ruvara, uye kukanganisa zvivakwa zvechigadzirwa.
5
Kubata kwemvura
Pps ine yakaderera mvura yekunyora, asi zvinyorwa zvinofanirwa kunge zvakaomeswa pa120 ~ 150 ℃ -3 ~ maawa mashanu usati wagadzirisa
