Nei Polyphenylene Sulfide (PPS) iyo yakanyanya mutengo-inoshanda nyanzvi yeinjiniya mapurasitiki

September 05, 2024

Nei Polyphenylene Sulfide (PPS) ndiyo yakanyanya mutengo-inoshanda nyanzvi yeinjiniya mapurasitiki

Polyphenylene Sulfide (PPS) anoona zvakare sePolyphenylene emagetsi emahara. Standard uye Advanced Polymers maererano nemutengo uye kuita.

PPs ndeyemiyo-crystalline engineering iyo inovhara iyo gapwe pakati pePolymers Polymers dzakakora uye dzakapetwa

PPs mashitsi, tsvimbo uye machubhu ane yakakwira dimensional kugadzikana panguva yekugadzirisa uye kushandisa, kuita kuti ive yakakodzera kune zvikamu zvakaoma nezvipenga chaizvo. Uye zvakare, pps mapurasitiki ane zvinhu zvakanakisa zvekushandisa, zvimiro zvemagetsi zvemagetsi, kupisa kwakanyanya uye murazvo kuramba.

Inowanzoshandiswa seyakaderera-inodhura neimwe nzira yekunyorera mari inoomesesa, pps mapurasitiki akanakisa mutoro wekutakura kupisa kwakanyanya.

‍

PPS ndeyekureba kwazvo nyika-inobata-inoshanda nyanzvi yeinjiniya mapurasitiki. Iyo yave iyo nhamba yeiyo nyanzvi yeinjiniya yeinjiniya. Mukunze kweiyo general-chinangwa engineering purassics, pps masmel mushure mePolycarbonate, polyester, polyformaldehyde, nylon uye polyphanylene ether, ine vhoriyamu yekugadzira munzvimbo ye6.

01 iyo yakanyanya mutengo-inoshanda nyanzvi yeinjiniya mapurasitiki

PPS Resin kazhinji ichena kana kuti ingangoita chena kana poda zvigadzirwa, nekuda kwechimiro charo chemarara uye kujairwa kukuru, saka iyo PPP ndeyePolyine Folymer, ine simba rakanyanya. modulus uye yakanaka dimensional kugadzikana kwechigadzirwa, kukwira zvidiki, pane iyo yakanyanya kupera simba, mukunyorova kwemamiriro ekunyanyisa, anokwanisa kuchengeta yakanaka yemagetsi yekunzwa, yakanaka solvent uye yemakemikari Kupokana, kwakaita kuti zviszwisiswe mune chero solvent pazasi 200 ×, uye radiation kuramba.

Muinjiniya mapurasitiki uye nyanzvi yeinjiniya mapurasitiki, PA, pom, pom uye imwe general engineering plastics Imide (Pai) yakanyanya kukwirira kana mutengo wakanyanya kukwirira, iyo PPS yave yakanyanya kunyorera application yezvinhu.

02 zvimiro zvemuviri uye michina

Semurume anorema ePPS anogadzirwa muchikamu chekutanga haana kukwira zvakakwana, iyo inoda kubatwa nayo brittle, iyo ndeimwe yemakona ayo makuru. Asi kubvira pakabuda kwepamusoro molecular uremu Kuti uve kuomarara kwePPS. Panguva imwecheteyo, kana ichienzaniswa neiyo thermo-oxygen crosslinked resins, yakakwira molecular uremu pps, iyo inopisa uye zvimwe zvekugadzira zvivakwa zvakavandudzwa zvakare. zvakavandudzwa.

Simba reSimba rakasimba uye rakashanduka-shanduka simba rePPs risiri repamusoro inongova pakati, uye kusakwana uye simba simba zvakare dzakaderera. Naizvozvo, pps inowanzo shandurwa nemarara egirazi uye mamwe magetsi emineral mafirita ekusimudzira nzvimbo yekuzadza, kuti inogona kuenderera mberi nekuvandudza midziyo yemuviri uye ichichengetedza kupesana nekudziya kupokana, kupfumisa kudzoreredza uye kuverenga kweMedia.

03 Thermal Properties

Iko kupisa kwekudzivirira kwePolymers kunoratidzwa zvakananga muhukuru hwemanyorerwe, kugadzikana kwehuremu kwekudzikama kwePolymist pps mune ese errmoplastic engineering mapurasitiki anoratidza zvakanakisa kupisa kupesana.

Pps yekunyunguduka poindi seyekumusoro kusvika 280 ℃ ℃, mumhepo 430 ~ of inosvika 260 ℃, kwenguva refu kushandiswa kwekudziya kweTemplastics kunogona kusvika kune yakakwira ye220 ~, iyo Simba rakakotama ra200 【ichiri yakakwira kupfuura mukamuri tembiricha saka itsermoplastic engineering mapurasitiki. Yakakwirira kupfuura mukamuri tembiricha inodya saka ndiyo yakanaka yakanyanya-tembiricha yekugadzira zvinhu.

PPS Solder Heat Kuramba zvakare zvakare yakakwira kupfuura mamwe mainjiniya mapurasitiki, achiita kuti iite yakakodzera kugadzirwa kwemagetsi uye magetsi zvikamu. Kuita kwakadaro kunopisa, kunyangwe muTermossa plastics isingawanzo. Uye zvakare, pps pachayo ine yakanaka yekudzivirira insulation, asi nekuwedzera yakakodzera filler, inogona zvakare kubereka yakanaka yekufambisa inonhuwirira yePPS composite zvinhu.

04 Chemical Resistance

Pps makemikari kuramba uye anonzi "Mambo wePurastics" PolytetraFluorohone (PPS) Sulfanizic Acids Alkalis, munyu, muna 200 ℃ Inzwa mune chero makemikari reagent. Pamusoro pekusimba oxdizizizizizing acid uye funy nitric acid, chlososulfonic acid, fluorine acid, ingadai isina kubviswa nenhau dzese dzeNorganic. Pamusoro pa250 Pakupisa kwakanyanya kunyange iyo yakanakisa solinen chlorinated bipherl inogona chete kunyungudusa 10%. MuBoiling yakamanikidzwa hydrochloric acid, pps haishanduke shanduko. Kugadziriswa kwakanaka kwePPS kwakakwirira kwazvo kune PTFE, kugadzira PPS kwakanyanya kushandiswa muPetroleum, maindasitiri emakemikari uye maindasitiri emakemikari anoda mafuta neokisheni.

05 Magetsi Zvivakwa

Pps uye mamwe mainjiniya mapurasitiki, achienzaniswa neodictric nguva pfupi, Difelectric Kurasikirwa kwakadzika, uye kufambidzana kazhinji kunowanzoitika pakati pegumi ne10-18 ~ 10-15S / cm .

PPS inogona kuramba ichiramba yakanaka yemagetsi zvemagetsi pakudziya kwakanyanya uye kunyorova kwakanyanya. Kunyangwe yakagadziridzwa kana kuti kwete, pps yemagetsi zvivakwa ne tembiricha uye nekushongedza shanduko zvidiki kwazvo, uye mune dzakasiyana siyana dzekudziya dzine zvimwe zvimedu zvemvura nemvura kana tembiricha ye120 ~ 150 ℃ ichiri yakagadzikana kwazvo.

Kazhinji, Thermoplastic kurwisa kwakaderera pane kurwisa purastics kwakanakisa,

Pps mune imwe nyaya yekupisa kwakanyanya, yakakwirira humidity kurwisa coeffication yekuchinja ndeye tembiricha iri diki, inogona kutsungirira 10s mu26 ℃ ℃ mutengesi wekugezera, Uye saka zvakakwana kuti tiregedze iyo yekuvhunduka kweiyo nzvimbo yekutengesa yezvirevo zvezvinhu zvemagetsi zvezvigadzirwa zvine chekuita nezvinhu zvemagetsi, chinhu chakanakisa kusimbisa kwemagetsi.

06 murazvo unodzoreredza

Kuti uvandudze kudzokorora kwemurazvo kwemidziyo yakawanda, inowanzo kuve yakafanira kuwedzera imwe huwandu hwemurazvo hwakadzoreredza, uye kuvapo kwemurazvo kudzora kunowanzobata zvivakwa zvemagetsi zvezvigadzirwa; Mukuita kwekuumbwa kuchaitawo imwe nhanho yekufananidza kwemidziyo, kuumbwa; Kana iyo yekurohwa ikaitika, murazvo unodzoreredza uchaburitsawo magasi ane chepfu, zvichikonzera matambudziko ekuchengetedza.

Pps nekuda kweiyo molecular chimiro ne sarufu maatomu, iyo jekiseni indekisi ye44% ~ 53%, inogona kusvika padanho repamusoro rekuchengetedza Kuti uwedzere murazvo unodzoreredza izvo zvinogona kusangana nezvinodiwa zvemurazvo, saka PPS zvinhu, zvakadai sedzidzo dzekuchengetedza kuti dziwane huwandu hwekushandisa mumutsara kune zvinodiwa zvePolymer mune chengetedzo. isina kujairika uye zvimwe zvinhu. Naizvozvo, pps inogona kushandiswa zvakanyanya mune zvimiti uye zvemagetsi zvevarindi zvekuchengetedza, izvo zvinoenderana nezvinodiwa zvePolymer maererano nekuchengetedza, zvisiri zvechisimba uye maitiro ayo ekuvandudza.

07 Adhisheni

PPS pagirazi, Aluminium, Cererics, simbi, Sirdelly Zvigadzirwa, Iyo Nickl-Yakatemwa Simba reSimbi ye20.58 ~ 22.54mpa yegirazi uye kunyange kupfuura simba regirazi regirazi. Nekuda kwekukonzeresa kupesana kwayo uye kunamatira zvivakwa, zvakakodzera kwazvo kugadzirira kwemakemikari emidziyo inoyerera.

08 Dimensional Kugadzikana

PPS ine yakanakisa dimensional kugadzikana, kuumba shrinkage uye mutsara wekuwedzera ceefficient idiki, kuumbwa shrinkage ye 0,15% kusvika 0,3%, yakaderera kusvika kune 0.01%. Uyezve, pps mvura neoiri zvekunyura idiki, uye kupokana kwakanaka kwemakemikari, mukunyoropodzwa, mafuta uye zvakashata gasi nharaunda, PPS Zvigadzirwa zvichiratidzika kuve kwakanakisa kugadzikana.

Mukuwedzera, kune mazhinji emapurasitiki emapuranga, kazhinji nekuda kwekunyora kwemvura, mukuumbwa kwehukama Xia Xia pane imwe nguva ichave nekuda kwekubuda kwemvura uye kugadzira mapuresita, kana kuumbwa maitiro nekuda kwekutsika kwemvura uye kukonzera kukwegura. Nekudaro, nekuda kwemvura yakadzika kwazvo yePP, nguva yekunyorova isati yadzikira inogona kuderedzwa kwazvo, uye nenzira, haizoburitse nekuda kwekunyorova uye kusvibiswa kwezvinhu zvisina kufanira.

Uye zvakare, kunyangwe pps yekunyungudika tembiricha yakakwira, asi iyo yekuvhara tembiricha yakaderera, yakanaka yekukasira, yakakodzera kugadzirisa muzvinhu zvakatetepa kana zvakaringana.

09 radiation kuramba

Pps yakagadzikana kune UV uye 60co raizhangu, kunyanya thermaly uye yemakemanicslinked pps inopesana ne107gy dhiini yeradiation.

10 zvimwe zvivakwa

PPS inzvimbo yepamhepo internet, yadarika, yadarika yeUS FDA Mavharuvhu, machubhu, etc. yakagadzirwa nePPs inoshandiswawo mukutumira kwehurongwa hwemvura.
