I-POMAmashidi, amapuleti nezinduku (i-polyoxymethylene) kuya ngokuya kubaluleka ezimbonini ezahlukahlukene ngenxa yamandla nokuqina kwazo okuphezulu. Lezi zinto ze-thermoplastic, ezaziwa nangokuthi amapulasitiki e-acetal, zinikeza izinzuzo eziningi, okuhlanganisa impilo enhle yokukhathala, ukuzwela okuphansi komswakama, kanye nokumelana okuphezulu nezincibilikisi namakhemikhali.
Esinye sezici ezihlukanisayo zeIshidi le-POMI-s yizakhiwo zabo ezinhle zikagesi. Lokhu kuzenza zibe ukukhetha okuthandwayo kwezicelo ezidinga ukufakelwa ugesi. Kungakhathaliseki ukuthi zisetshenziselwa ukukhiqiza izingxenye eziqondile ezizinzile noma izingxenye zokufakelwa ugesi, amashidi e-POM aguquguquka kakhulu.
Enye yezinkambu lapho amashidi e-POM esetshenziswa khona kakhulu imishini yemishini. Amandla nokuqina kwawo kuwenza afanelekele ama-modulus amancaneamagiya, amakhamera, amabheringi nama-roller agcwele kakhulu, kanye namagiya amancane okubuyela emuva kanyeibheres. Lezi zinhlelo zokusebenza zidinga izinto ezingamelana nemithwalo ephezulu futhi zinikeze ukusebenza okubushelelezi nokuthembekile. Amashidi e-POM avelele kulezi zici, okwenza afaneleke kakhulu kulezi zingxenye.
Okunye ukusetshenziswa okubalulekile kweshidi le-POM emishinini yemishini yisihlalo se-valve. Izihlalo ze-valve zidlala indima ebalulekile ekulawuleni ukugeleza koketshezi futhi ziguga kakhulu. Ishidi le-POM linikeza ukuqina nokuthembeka kwezicelo zokuhlala ze-valve ezinokumelana okuhle kakhulu kwe-solvent kanye namakhemikhali kanye nokuphila isikhathi eside kokukhathala.
Ishidi le-POMAma-s ayatholakala futhi ukuze afaneleke. Ama-Snap-fit assembly asetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi izimoto, izinto zikagesi, kanye nezimpahla zabathengi. Lezi zingxenye zidinga ukubopha izingxenye ezahlukene ndawonye ngokuphephile ngenkathi zivumela ukuhlanganiswa nokuhlukaniswa okulula. Amandla nokuqina kwamashidi e-POM kunikeza ukwesekwa okudingekayo kanye nokuguquguquka kwezinhlelo zokusebenza ze-snap-fit.
Ngaphezu kwalokho, amashidi e-POM asetshenziswa kabanzi ekukhiqizweni kwezingxenye zokunemba ezizinzile ngokwesilinganiso. Lezi zingxenye zidinga ukunemba okuphezulu ngokwezinga lokubekezelelana kanye nokunemba kwesilinganiso. Ukuqina okuhle kakhulu kwezilinganiso zamashidi e-POM kuqinisekisa ukuthi umkhiqizo wokugcina uzohlala uhlangabezana nezidingo ezidingekayo.
Ekuphetheni, ishidi le-POM liyisinqumo esithembekile nesiguquguqukayo sezinhlelo zokusebenza ezahlukahlukene zemishini ngenxa yamandla alo aphezulu, ukuqina kanye nezinye izakhiwo eziwusizo. Kusukela kumagiya kuya kuma-bearings anzima, izihlalo zama-valve kuya ezingxenyeni ezilingana kahle, amashidi e-POM anikeza ukuqina, ukuthembeka kanye nokusebenza kahle. Ngaphezu kwalokho, izakhiwo zawo ezinhle zikagesi ziwenza afanelekele ukusetshenziswa njengezinto zokuvikela zikagesi. Uma udinga izinto ezingamelana nemithwalo ephezulu, zinikeze ukuzinza kobukhulu futhi zibonise izakhiwo zikagesi ezinhle kakhulu, ishidi le-POM likufanele ngempela ukucatshangelwa.
