Polyphenylene Sulfide (PPS) yog dab tsi?

Polyphenylene Sulfide (PPS) yog ib hom thermoplastic polymer semi-crystalline nrog lub ntsej muag daj ntseg. Nws muaj qhov chaw yaj ntawm kwv yees li 290 ° C thiab qhov ceev ntawm kwv yees li 1.35 g / cm³. Nws cov qauv molecular - ua los ntawm cov nplhaib benzene alternating thiab sulfur atoms - ua rau nws muaj cov qauv ruaj khov thiab ruaj khov heev.

PPS paub txog nws qhov kev tawv siab, kev ruaj khov zoo heev, kev tiv taus tshuaj lom neeg, thiab lub zog kho tshuab. Vim nws qhov kev ua tau zoo tshaj plaws, PPS tau lees paub dav dav tias yog ib qho ntawm rau lub yas engineering loj, nrog rau polyethylene terephthalate (PET), nylon (PA), polycarbonate (PC), polyoxymethylene (POM), thiab polyphenylene ether (PPO).

Cov Ntawv thiab Cov Kev Siv ntawm PPS

Cov khoom Polyphenylene Sulfide (PPS) muaj ntau hom thiab qib, xws li cov resins, fibers, filaments, zaj duab xis, thiab coatings, ua rau lawv siv tau ntau yam. Cov chaw siv tseem ceeb ntawm PPS suav nrog kev lag luam tsheb, hluav taws xob thiab electronics, kev lag luam tshuaj lom neeg, tub rog thiab kev tiv thaiv, textile sector, thiab kev tiv thaiv ib puag ncig.

Cov Teeb Meem Feem Ntau Hauv PPSekev tsim kho yasthiab Yuav Ua Li Cas Thiaj Li Daws Tau Lawv

Txawm hais tias nws cov khoom zoo heev, PPS engineering plastics tseem ntsib ntau yam teeb meem hauv kev ua thiab kev ua tau zoo hauv kev siv. Nov yog peb qhov teeb meem feem ntau thiab lawv cov kev daws teeb meem:

1. Kev tawg yooj yim hauv PPS uas tsis tau ntim

Kev Sib Tw: PPS uas tsis tau ntim puv yog qhov tsis ruaj khov, txwv tsis pub siv rau hauv cov ntawv thov uas xav tau kev tiv taus kev cuam tshuam siab lossis kev ywj pheej (piv txwv li, cov khoom uas raug kev poob siab lossis kev co).

Ua rau:

Qis elongation thaum tawg vim nws cov qauv molecular rigid.

Tsis muaj cov additives los txhim kho lub zog.

Cov Kev Daws Teeb Meem:

Siv cov qib PPS uas muaj cov iav fiber (piv txwv li, 40% iav puv) lossis cov khoom siv minerals kom txhim kho lub zog thiab kev tawv ntawm kev cuam tshuam.

Sib xyaw nrog elastomers lossis cov khoom hloov pauv rau cov ntawv thov tshwj xeeb.

2. Kev nplaum tsis zoo rau cov txheej txheem lossis kev sib txuas

Kev Sib Tw: PPS cov tshuaj lom neeg tsis muaj zog ua rau nws nyuaj rau cov nplaum, cov tshuaj pleev xim, lossis cov xim kom lo, ua rau kev sib dhos lossis kev ua tiav ntawm qhov chaw nyuaj (piv txwv li, hauv cov tsev hluav taws xob lossis cov khoom lag luam coated).

Ua rau:

Lub zog nto qis vim yog PPS cov qauv tshuaj tsis yog polar.

Kev tiv thaiv kev sib txuas tshuaj lom neeg lossis kev ntub dej ntawm qhov chaw.

Cov Kev Daws Teeb Meem:

Siv cov kev kho mob saum npoo xws li plasma etching, corona discharge, lossis chemical priming kom nce lub zog ntawm qhov chaw.

Siv cov nplaum tshwj xeeb (piv txwv li, epoxy lossis polyurethane-based) tsim rau PPS.

3. Kev Hnav thiab Kev Sib Txhuam hauv Cov Ntawv Thov Dynamic

Kev Sib Tw: Cov qib PPS uas tsis tau ntim lossis cov qib PPS txheem qhia txog kev hnav lossis kev sib txhuam ntau hauv cov khoom txav xws li cov kabmob, cov iav, lossis cov foob, ua rau tsis ua haujlwm sai sai hauv cov ntawv thov dynamic.

Causes:

Cov coefficient ntawm kev sib txhuam siab heev hauv PPS tsis tau ntim.

Kev nplua nplua tsawg thaum muaj kev thauj khoom ntau lossis kev txav mus tas li.

Cov Kev Daws Teeb Meem:

XaivCov qib PPS uas muaj roj nplua nyeem nrog cov khoom ntxivzoo li PTFE, graphite, lossis molybdenum disulfide los txo qhov kev sib txhuam thiab txhim kho kev hnav tsis kam.

Siv cov qib uas muaj zog (piv txwv li, cov roj carbon fiber uas muaj) rau qhov muaj peev xwm nqa tau ntau dua.

SILIKE Cov Khoom Siv Ua Kom Lubricant Thiab Cov Khoom Hloov Kho Nto Rau PPS Engineering Plastics

Cov Kev Daws Tshiab rau Kev Txhim Kho Kev Tiv Thaiv Kev Hnav ntawm PPS Sliding Components

Taw qhia cov khoom siv silicone SILIKE LYSI-530A thiab SILIMER 0110

LYSI-530A thiab SILIMER 0110 yog cov khoom siv roj nplua nyeem tshiab thiab cov khoom hloov kho qhov chaw rau polyphenylene sulfide (PPS), uas SILIKE nyuam qhuav tsim tawm. Cov khoom ntxiv silicone no ua haujlwm zoo ib yam li polytetrafluoroethylene (PTFE), uas muaj lub zog qis ntawm qhov chaw. Yog li ntawd, lawv txo qhov hnav thiab qhov sib txhuam ntawm PPS composites.

Cov tshuaj ntxiv no muaj qhov sib txhuam qis heev thiab ua haujlwm ua cov roj nplua nyeem sab hauv. Lawv tsim ib daim nyias nyias ntawm qhov chaw ntawm PPS thaum raug rau lub zog txiav, yog li txo qhov kev sib txhuam ntawm PPS thiab cov chaw sib koom ua ke, tsis hais seb lawv yog hlau lossis yas.

Los ntawm kev siv tsuas yog 3% LYSI-530A, qhov sib txhuam dynamic tuaj yeem txo qis mus rau ib puag ncig 0.158, ua rau muaj qhov chaw du.

Tsis tas li ntawd xwb, kev ntxiv 3% SILIMER 0110 tuaj yeem tau txais qhov sib txhuam qis ntawm kwv yees li 0.191 thaum muab kev sib txhuam sib npaug rau qhov uas muab los ntawm 10% PTFE. Qhov no qhia txog qhov ua tau zoo thiab lub peev xwm ntawm cov khoom ntxiv no hauv kev txhim kho kev ua tau zoo thiab kev ua haujlwm ntev thoob plaws ntau yam kev siv, Zoo tagnrho rau kev swb, tig, lossis dynamically loaded PPS qhov chaw.
