Polifhenylene Sulfide ni iki (PPS)?

Polyphenylene Sulfide (PPS) ni igice cya kirisiti ya kirisiti ya polimoplastike ya polymer ifite isura yumuhondo yijimye. Ifite aho gushonga igera kuri 290 ° C n'ubucucike bwa 1,35 g / cm³. Umugongo wacyo wa molekuline-ugizwe no guhinduranya impeta ya benzene na atome ya sulfure - itanga imiterere ikomeye kandi ihamye.

PPS izwiho gukomera kwinshi, guhagarara neza kwubushyuhe, kurwanya imiti, nimbaraga za mashini. Bitewe n'imikorere idasanzwe, PPS izwi cyane nka imwe muri esheshatu nini za plastiki zubuhanga, hamwe na polyethylene terephthalate (PET), nylon (PA), polyakarubone (PC), polyoxymethylene (POM), na polifhenylene ether (PPO).

Imiterere na Porogaramu ya PPS

Ibicuruzwa bya polifenilene Sulfide (PPS) biraboneka muburyo butandukanye no mu byiciro, nka resin, fibre, filaments, firime, hamwe na coatings, bigatuma bihinduka cyane. Ibice byingenzi bikoreshwa muri PPS harimo inganda zitwara ibinyabiziga, amashanyarazi na elegitoronike, inganda z’imiti, ingabo n’ingabo, urwego rw’imyenda, no kurengera ibidukikije.

Ibibazo bisanzwe muri PPSengineering plastike and Uburyo bwo kubikemura

Nuburyo bwiza cyane, plastike yubuhanga bwa PPS iracyafite ibibazo byinshi byo gutunganya no gukora mubikorwa bifatika. Hano haribibazo bitatu bikunze kugaragara nibisubizo bihuye:

1. Ubukorikori muri PPS ituzuye

Ikibazo: PPS itujujwe isanzwe ivunika, igabanya imikoreshereze yabyo isaba guhangana ningaruka zikomeye cyangwa guhinduka (urugero, ibice bishobora guhungabana cyangwa kunyeganyega).

Impamvu:

Kurambura hasi kuruhuka kubera imiterere ya molekile ikomeye.

Kubura inyongeramusaruro zo kongera ubukana.

Ibisubizo:

Koresha amanota ya PPS ashimangiwe hamwe na fibre y'ibirahure (urugero, 40% byuzuye ibirahuri) cyangwa ibyuzuza minerval kugirango utezimbere imbaraga no gukomera.

Kuvanga na elastomers cyangwa impinduka zimpinduka kubikorwa byihariye.

2. Guhuza nabi kubitwikiriye cyangwa guhuza

Ikibazo: Kutagira imiti ya PPS ituma bigorana gufatisha, gutwikira, cyangwa gusiga irangi kubahiriza, bigoye guterana cyangwa kurangiza hejuru (urugero, mumazu ya elegitoroniki cyangwa ibice byinganda).

Impamvu:

Ingufu zo hasi kubera imiterere ya PPS idafite polar.

Kurwanya guhuza imiti cyangwa guhanagura hejuru.

Ibisubizo:

Koresha uburyo bwo kuvura nka plasma etching, corona isohoka, cyangwa chimique priming kugirango wongere ingufu zubutaka.

Koresha ibikoresho byihariye (urugero, epoxy cyangwa polyurethane-ishingiye) yagenewe PPS.

3. Kwambara no Kuvunika muri Dynamic Porogaramu

Ikibazo: Impamyabumenyi ya PPS itujujwe cyangwa isanzwe yerekana igipimo cyinshi cyo kwambara cyangwa guterana ibice byimuka nkibikoresho, ibyuma, cyangwa kashe, biganisha kunanirwa imburagihe mubikorwa byingirakamaro.

Cimpamvu:

Ugereranije coefficente yo hejuru yo guterana muri PPS ituzuye.

Amavuta make munsi yimitwaro myinshi cyangwa kugenda bikomeza.

Ibisubizo:

Hitamoamavuta ya PPS amanota hamwe ninyongeranka PTFE, grafite, cyangwa molybdenum disulfide kugirango ugabanye ubukana kandi wongere imbaraga zo kurwanya.

Koresha amanota ashimangiwe (urugero, karuboni fibre yuzuye) kubushobozi bwo gutwara ibintu byinshi.

SILIKE Ibikoresho byo gutunganya amavuta hamwe nubuso bwa Surface ya PPS yubuhanga

Ibisubizo bishya byo kuzamura imyambarire irwanya ibice bya PPS

Kumenyekanisha inyongera zishingiye kuri silicone SILIKE LYSI-530A na SILIMER 0110

LYSI-530A na SILIMER 0110 ni ibikoresho bishya byo gutunganya amavuta hamwe noguhindura isura ya polifenile sulfide (PPS), iherutse gutangizwa na SILIKE. Izi nyongeramusaruro zishingiye kuri silicone zikora kimwe na polytetrafluoroethylene (PTFE), irangwa nimbaraga nke zo hejuru. Nkigisubizo, bagabanya cyane igipimo cyo kwambara hamwe na coefficient de fraisse ya compte ya PPS.

Izi nyongeramusaruro zerekana coefficient nkeya idasanzwe kandi ikora nkamavuta yimbere. Zibyara firime yoroheje hejuru ya PPS mugihe ikozwe ningufu zogosha, bityo bikagabanya ubushyamirane buri hagati ya PPS nubusabane, utitaye ko ari ibyuma cyangwa plastiki.

Ukoresheje 3% gusa LYSI-530A, coefficente de dinamike yo kugabanuka irashobora kugabanuka kugera kuri 0.158, bikavamo ubuso bunoze.

Byongeye kandi, hiyongereyeho 3% SILIMER 0110 irashobora kubona coefficente yo hasi ya 0.191 mugihe itanga irwanya abrasion ihwanye na 10% PTFE. Ibi birerekana imikorere nubushobozi bwibi byongeweho mugutezimbere imikorere no kuramba mubikorwa bitandukanye, Ideal yo kunyerera, kuzunguruka, cyangwa ibice byuzuye bya PPS.

SILIKE itanga imikorere-yo hejurusilicone ishingiye kumavuta hamwe nibikoresho bifasha gutunganyakumurongo mugari wa porogaramu. Inyongeramusaruro zacu zagenewe kunoza imikorere yo gutunganya no kuzamura imiterere yubutaka muri plastiki zahinduwe.

Urashaka inyongera iboneye yo gukora? Hitamo SILIKE - ibisubizo byacu bishingiye kuri silicone birashobora kugutangaza nibikorwa byabo.
Kongera imikorere ya PPS hamwe ninyongera zishingiye kuri silicone zigabanya guterana no kwambara - nta PTFE ikenewe ..
