Njenge-thermoplastic ephezulu ye-thermoplastic, i-peek isetyenziswa ngokubanzi kwi-aerospace kunye nemveliso yemoto ngenxa yezakhiwo ezibalaseleyo zomzimba kunye neekhemikhali. Nangona kunjalo, izinto ezibonakalayo kunzima ukuziqhubela phambili, ezizisa imiceli mngeni ethile kumzi mveliso wokwenza. Kweli phepha, siya kuhlalutya ubunzima boomatshini wezixhobo ze-PERE kwiimpawu zezixhobo ze-Peks kunye nokucebisa ukuba izinto ezifanayo.
I. Ukwaziswa kwezinto ze-Peek
I-Polyeether Ether Ketone (i-peek) yi-thermoplastic ngentsebenzo ebalaseleyo, kunye neempawu ezilandelayo:
Ukunganyangeki kobushushu obuphezulu: Indawo yokunyibilika ye-Peek ikwi-340 ℃, inokusetyenziselwa ixesha elide kwindawo yobushushu obuphezulu.
Ukuxhathisa iikhemikhali: I-Peek ineenjongo ezifanelekileyo zeekhemikhali kwaye ixhathise ii-acids, ialkalis, iityuwa kunye nezinye izinto ezibonakalayo.
Ukunganyangeki kwe-abrasion: I-Peks inesigqibo esihle kakhulu sokunganyangeki kwaye ilungele ukusetyenziswa kwengqumbo kwaye inxibe.
Amandla aphezulu: I-Peek ineepropathi ezigqwesileyo, ngamandla aphezulu kunye nobungqola obuphakathi.
Okwesibini, i-Peek yeZinto eziKhutshoyo
Nangona izinto ze-Pekk zinezibonelelo ezininzi, kodwa ubunzima bayo, ikakhulu kwezi ndawo zilandelayo:
Ukusika ubunzima: Ubunzima obuphezulu beempahla ze-Peks, inkqubo yokusika kulula ukuvelisa ubushushu obuphakamileyo, okukhokelela ekunxibe kakuhle izixhobo.
I-hygroscoficity: Impahla ye-Peek inee-hygroscoficity, inkqubo yokulungisa ilula ukufuma, ikhokelela kwiinguqu ezinkulu.
Kulula ukuvelisa i-Burr: Impahla ye-Peks kwinkqubo yokulungisa, kulula ukuvelisa i-burr, echaphazela ukuchaneka kwemveliso.
Ukusebenza okukhulu kulwandiso lwe-shirm: Impahla ye-Peks inendawo enkulu yokwandiswa kwe-shirmal kwaye ixhaphakile kwingxaki ye-thermal ngexesha lokuqhutywa.
Uxinzelelo lwentsalela: Izixhobo ze-Peks zithambekele kuxinzelelo lwentsalela ngexesha lokuqhutywa kwemveliso.
Okwesithathu, i-Peek yeZinto eziSebenzayo
Ngobunzima bokusebenza kwezixhobo ze-Peek, ezi zinto zilandelayo:
Ukukhetha izixhobo ezifanelekileyo zokusika: Ukukhetha i-carbide kunye nezinye izixhobo zokusebenza eziphezulu ukuphucula isiphumo sokusika.
Yenza iiparameter zokusika: Ngokweempawu zezinto ze-Peks, lungisa isantya sokusika, ukutya, ubunzulu bokusika kunye nezinye iiparamitha ukunciphisa ubunzima.
Ukwamkela iindlela ezifanelekileyo zokupholisa: Sebenzisa ukupholisa amanzi kunye nezinye iindlela ukunciphisa ubushushu kwinkqubo yokusika kunye nokunciphisa isixhobo.
Ukulawulwa kwe-themidity: yomisa impahla ye-Peks ngaphambi kokuba isebenze ukunciphisa isiphumo sokuthantamisa komswakama kubungakanani.
Thintela ukuSebenza kwe-Irmal: Ulungiselelo olufanelekileyo lwendlela yoomatshini ukunciphisa ukufezekiswa kwengqondo.
Thatha amanyathelo aphantsi
Izinto ze-Pekks zinoluhlu olubanzi lwezicelo kwimimandla emininzi ngenxa yokusebenza kwayo ngokugqwesileyo. Nangona kunjalo, ukuqhubekeka kwayo kunzima, okuzisa imiceli mngeni ethile kumzi mveliso wokwenza. Ngokuhlalutya iimpawu kunye nokuqhubela phambili kwempahla ye-Peks kunye nokuqikelela ukubaluleka okungqinelana, kuyanceda ukuphucula inqanaba lokuqhubela phambili kwezinto ze-Pekk.
