Nguwuphi umahluko phakathi kwe-peek kunye ne-PPS?

I-PPS (i-polyphenyne sulfide) yiplastiki ekhethekileyo yobunjineli enolusu olusezantsi, ukumelana nokungazinzanga okuqinisekileyo, ukubuyiswa kombane okuphezulu, kunye nokuxhaswa kobushushu obuphezulu. Ukufuma okuphezulu kunokugcina izinto ezilungileyo zombane. I-fluindity elungileyo, kulula ukuyikha, phantse akukho chitho zokucoca xa kusenziwa. Kwaye inobubele obulungileyo ngeefilimu ezahlukeneyo ze-inorganic. Isetyenziswe ngokubanzi ngenxa yokusebenza kwayo kakuhle, ngakumbi ilungele indawo enobungozi necolisekileyo.

I-Peek (Polyteether Ether Itone) yiplastiki ekhethekileyo yobunjineli enepropathi ebanzi, ukuxhathisa ubushushu, ukunganyangeki kwamachiza, i-radical ye-rames, njl. Njl. Inkcazo, kwaye ivelise i-Medical efunwayo efunwayo njengeegiya, iibheringi, izihlalo zeValve, ezityhalela amakhonkco, impompo inxibe-i-pump.

Ke ngowuphi umahluko ophambili phakathi kwe-PPS kunye ne-Peek Ausk?

1. Ngokuphathelele ukunganyangeki kobushushu, i-Peek inobushushu obude obunobushushu obungama-250 ° C, iqondo lokushisa eliphawulekileyo lama-300 ° C, iphantse yabakho kwi-400 ° C ngexesha elifutshane; I-PPs inokusetyenziswa kwi-220 ° C ixesha elide, kwaye inokufikelela kuma-260 ° C ngexesha elifutshane. Inqaku lokunyibilika: I-PPs iku-280 ° C, i-Peek ikwi-340 ° C, kwaye i-Peek inokugcina iipropathi eziphezulu kunye namandla omatshini nakwamachwephesha.

2. Ngokuphathelele ubunzima, nokuba yinto ecocekileyo okanye i-fibren firn fiption, i-elonginger kwikhefu lincinci kunaleyo ye-PERK; Ngokuphathelele kwamandla e-thensle, i-PPS yi-105MPA, ngelixa i-teek i-115MPA. Ngokubanzi, i-Peek iphezulu kune-PPS Fiber Fiber eqinisa iimveliso ngokwemigaqo yamandla e-thensile, amandla e-frexus, ubushushu obuguqukayo kunye nobushushu obuguqukayo. I-PPS kunzima ukuyibuyisela xa kuphela i-peeki ifumaneka, ngakumbi kubushushu obuphezulu.

3. Ngokweendleko, nangona i-PPS kunzima ukuyibuyisela i-PERTE ngokwendlela yokusebenza, umahluko wamaxabiso phakathi kwezi zimbini, kwaye ukusetyenziswa kwe-PPs kunokunciphisa kakhulu iindleko. Ukuba ukusebenza kwe-Peek kugqithisa iimeko ezithile zomsebenzi okanye kwizihlandlo ezithile ezinzima okanye ubushushu obuphantsi, ii-PPs zingasetyenziswa endaweni yoko.

Kwiimeko ezininzi, kunzima ukuthelekisa i-PPS nge-PPS ye-POSE, ngenxa yokuba i-Peek ivela emva kwayo yonke iklasi ePhezulu yePlastiki ephezulu. Iipropathi ezimbalwa zempahla ziziphatha ngendlela efanayo, njengokuchaswa kwelanga, iipropathi zombane kunye neepropathi zombane.
Ingakumbi ngokubhekisele kwiipropathi ze-thermal kunye noomatshini, ukuthelekiswa phakathi kwePPS vs veevors peevers peevers peev. Nangona i-PPS ibonelela ngamandla aphezulu oxinzelelo oluphezulu xa kuthelekiswa ne-peek (kwi-5% ye-5% ye-102 MPA VS. PPS = 134 MPA). I-Peek inomhlaba ophakameyo Oku kukhokelela kumandla aphezulu aphezulu (i-peek = 166 MPA vs. PPS = 103 MPA) kunye namandla aphezulu epelisi (i-charpy chart = 2,6 kj / m2) xa kuthelekiswa ne-PPs engafakwanga.

Ukongeza, i-PPS engaphantsi ye-PPS xa ithelekiswa ne-Peks ichaphazela indlela yokuziphatha ebonakalayo, ebonakaliswa yimo ye-Burr encinci kunye neetshipsi ezimfutshane, kodwa umngcipheko ophezulu wokuqhekeka.

Kwezinye izicelo, ukufuna imisebenzi kamatshini ukuze kufezekiswe izakhiwo okanye imicro-micro, i-PPS inokukhokelela kwiziphumo ezingcono kune-PERK.

Ngokubanzi, zombini iideki ze-peek kunye ne-PPS zinozinzo oluhle kakhulu ngokwemigaqo yokufumana amanzi kunye nokwandiswa kwe-shirmal. I-PPS ibonisa ukufunxa kancinci amanzi asezantsi, ngelixa i-peki ibonisa amanqanaba asezantsi aphantsi kolwandiso lomoya. Ngelixa i-clte ye-PPS iphantsi ukuya kwi-100 ° C (ene-6 *), k), i-clte inyuse kakhulu (ukuya kwi-11 ukuya kwi-11-5 / k kwi-100 ~ 05 ° C) kwiindawo ezingaphezulu kweglasi ubushushu benguqu.

Ukongeza kwizibonelelo ze-Peek enexesha eliphakamileyo, amandla kunye nokuxhathisa kobushushu xa kuthelekiswa ne-PPs, enye inzuzo ye-Peek kukunganyangeki ngcono. Idatha engezantsi ibonisa uvavanyo lokuthelekisa lovavanyo lwe-CMP eyahlukileyo yokugcina amakhonkco.

Iinzuzo ze-Peek ngaphezulu kwe-PPS zibonakaliswa kwiindleko zokuthelekisa - i-peek ilukhetho olubizayo. Ke ngoko, iplastiki ye-PPS yindlela elungileyo ngakumbi xa iipropathi zezinto ezibonakalayo zigqitha ngokucacileyo kwiimfuno. Kwiimeko ezininzi, enye i-PPS ye-PPS ye-PPS yeyokhetho olungcono.

Ukongeza kumxholo wobunjineli obungaphezulu, izixhobo ze-PPS zinokufumana isigqibo
