Njengeplastiki yobunjineli eshushu enezakhiwo ezomeleleyo ezibanzi kwiminyaka yakutshanje, ibhodi yePOM isetyenziswa kakhulu kushishino lokwakha nakwishishini lokuvelisa.Abanye abantu bade bacinge ukuba ibhodi ye-POM inokutshintsha izinto zetsimbi ezifana nentsimbi, i-zinc, ubhedu kunye ne-aluminium.Ekubeni ibhodi ye-POM yiplastiki yobunjineli be-thermoplastic enendawo ephezulu yokunyibilika kunye ne-crystallinity ephezulu, kufuneka iguqulwe kwaye iphuculwe xa isetyenziswe kwiimeko ezahlukeneyo zesicelo.
Izinto ze-POM zineempawu zokuqina okuphezulu, ukumelana nokunxiba, ukuxhathisa ukufuma, ukuxhathisa kwimichiza, njl njl. Inokumelana ne-fuel, ukumelana nokudinwa, amandla empembelelo ephezulu, ukuqina okuphezulu, ukuxhathisa okuphezulu, ukuzinza okuhle kwe-dimensional, self-lubricating. iqondo eliphezulu lenkululeko yoyilo kwaye ingasetyenziswa ixesha elide kwi -40 ukuya kwi-100 °C.Nangona kunjalo, ngenxa yoxinaniso oluphezulu lwesalamane, amandla empembelelo yenotshi aphantsi, ukuxhathisa ubushushu akulunganga, ayifanelekanga ukubuyiswa komlilo, ayifanelekanga kushicilelo, kwaye isantya sokucutheka sokubumba sikhulu, ngoko ke ukuguqulwa kwe-POM kukulungele ukhetho olungenakuphepheka.I-POM ilula kakhulu ukuyiqaqambisa ngexesha lenkqubo yokwenza kwaye ivelise ii-spherulites ezinkulu.Xa izinto zichaphazeleka, ezi spherulites ezinkulu zithande ukwenza amanqaku oxinzelelo kwaye zenze umonakalo wezinto eziphathekayo.
I-POM inovelwano lwenotshi ephezulu, amandla empembelelo yenotshi ephantsi, kunye nesantya esiphakamileyo sokucutheka.Imveliso ixhomekeke kuxinzelelo lwangaphakathi kwaye kunzima ukwenza ngokuqinileyo.Oku kunciphisa kakhulu usetyenziso lwe-POM kwaye alukwazi ukuhlangabezana neemfuno zoshishino kwezinye iinkalo.Ngoko ke, ukuze ulungelelanise ngcono iimeko zokusebenza ezibukhali ezifana nesantya esiphezulu, uxinzelelo oluphezulu, ubushushu obuphezulu, kunye nomthwalo ophezulu, kunye nokwandisa ububanzi besicelo se-POM, kuyimfuneko ukuqhubela phambili ukuphucula Ukuqina kwempembelelo, ukuxhathisa ubushushu kunye nokumelana nokuxhatshazwa. yePOM.
Isihluthulelo sokuguqulwa kwe-POM kukuhambelana phakathi kwezigaba zenkqubo edibeneyo, kunye nophuhliso kunye nophando lwe-multifunctional compatibilizers kufuneka lwandiswe.Inkqubo yejeli esanda kuphuhliswa kunye ne-in-situ polymerized ionomer toughening yenza inkqubo edibeneyo yenze uthungelwano oluzinzile lwe-interpenetrating, oluyindlela entsha yophando yokusombulula ukuhambelana kwe-interphase.Isitshixo sokuguqulwa kweekhemikhali silele ekuqalisweni kwamaqela amaninzi kwi-chain chain chain ngokukhetha i-comonomers ngexesha lenkqubo yokudibanisa ukubonelela ngeemeko zokuguqulwa okuqhubekayo;ukulungelelanisa inani le-comonomers, ukulungelelanisa uyilo lwe-molecular structure, kunye nokudibanisa i-serialization kunye nokusebenza kunye ne-POM ephezulu yokusebenza.
