Polyphenylene sulfide (pps), nrog ib qho symmetrical rigid backuminium, yog ib nrab crystalline polymer muaj kev rov ua dua para-hloov cov nplhaib sib tw thiab cov txiv leejtenfur atoms. PPS yog qhov tshwj xeeb engineering yas nrog kev ua tau zoo thiab muaj peev xwm zoo li ntawm 280 ℃, uas tuaj yeem hloov cov hlau. Cov khoom zoo tshaj plaws ntawm PPS cob qhia ua kom nws raws li cov ntaub ntawv uas xav tau ntawm cov khoom siv tsheb uas xav tau.
PPS muaj ntau cov kev siv hauv kev lag luam hauv tsheb, thiab kev thov rau Is Nrias teb, thiab Nyij Pooj yog qhov yuav tsum tau ua rau lub tsheb.
PPS resin muaj cov yam ntxwv hauv qab no:
1. Inherent nplaim retardancy, ul94: qib v-0 / 5Va tsis muaj ntxiv nplaim retardant;
2. Cov tshuaj lom neeg zoo heev, ncav cuag cov kev daws teeb meem - tsis pub dhau los ntawm cov tshuaj lom neeg theem PTFE;
3. Qhov zoo nyob ruaj khov, qis moulding shrinkage thiab linear nthuav kev coefficient; Vim tias cov dej nqus dej tsawg, kev ruaj khov zoo yuav ua tau kuj tseem tuaj yeem tswj cov av noo thiab kev kub siab ib puag ncig
4. Koj cov khoom siv zoo, muaj zog siab thiab muaj zog, nws tuaj yeem ua kom muaj zog tsis kam thiab nkag hauv ib puag ncig;
5. Cov tshav kub ua tsis tau zoo, UP qhov ntsuas kub: 200-2-2-2-2-2-2-2-2-2-2-2-2-2 260 ℃.
PPS ntshiab tau tsis tshua siv ib leeg vim nws brittleness. Kev thov PPS feem ntau nws hloov kho ntau yam, uas feem ntau hloov kho los ntawm kev ntxiv cov iav fiber ntau.Cov lus hauv qab no sau cov ntawv thov cuam tshuam ntawm cov PPS hloov kho hauv lub tsheb lag luam:
| Cov lus piav qhia | Cov cim loj | Cov Ntawv Thov |
| PPS + 40% GF | 40% iav fiber cuam tshuam, muaj zog, muaj kev kub ntxhov ntau, cov roj kub thiab tshuaj lom neeg tsis ruaj khov | Twj tso kua mis impellers, cov vaj tsev valve thiab bushings, kauj vab khaub ncaws, teeb ci ntsa iab, teeb lub thawv roj teeb, thiab lwm yam. |
| PPS + 65% (GF + MF) | 65% khob fiber ntau / cov ntxhia txhawb nqa, zoo heev qhov ruaj khov, siab kub, siab tawv, siab ua tiav | Nws sib xyaw ua ke valve txuas, muaj kev kub siab kub, cov tsev twj tso kua mis, thiab lwm yam. |
| PPS + 30% CF | 30% Cov Fiber Fiber txhawb, Kev Ua Hluav Taws Xob Kub thiab Thermal thiab thermal thiab cov tshuaj tiv thaiv ntev, siab lub zog | Ntxuam pob zeb, nres lub tes tsho, qauv qauv rotor rotor tuaj, Cheebtsam clutch, bushings, thiab lwm yam. |
| PPS + 30% GF + 15% PTFE | 30% iav fiber ntxiv ntxiv, 15% PTFE lubricated, siab thermal deformation stability, muaj lub zog siab, txhim kho kev sib txhuam, zoo hnav kev tiv thaiv | Cov tshuaj tiv thaiv, manifolds, nqus, pistons, bearings, tswj hwm, zog, tswj cov iav qhov chaw, thiab lwm yam. |
| Cua txias dawb | Thermal conductivity, rwb thaiv tsev hluav taws xob, nplaim retardant, ul94 v0, lub zog zoo thiab muaj zog | Lub dab dej sov, cov khoom siv muaj zog, coj khaub ncaws, thermal Circuit Coas, cov khoom cua txias, thiab lwm yam. |
Sikopolers 'qib tseem ceeb ntawm PPS thiab lawv cov hom sib txig sib luag thiab qib, raws li hauv qab no:
