CNC izixhobo zomatshini
CNC Machining in POM
Iiplastiki zezinye izinto eziqhelekileyo ezisetyenziswa ekujikeni kwe-CNC kuba zifumaneka kwiinketho ezininzi ezahlukeneyo, azibizi kakhulu, kwaye zinamaxesha omatshini okhawulezayo.Iiplastiki ezisetyenziswa ngokuqhelekileyo ziquka i-ABS, i-acrylic, i-polycarbonate kunye ne-nylon.
I-POM (Polyoxymethylene) Inkcazo
I-POM, eyaziwa ngokuba yi-acetal okanye i-Delrin, yimpahla ye-thermoplastic eneempawu ze-semi-crystalline.Ithathwa kakhulu ngenxa yamandla ayo akhethekileyo, ukuqina kunye neempawu eziphantsi zokukhuhlana.I-POM isoloko isetyenziswa kwizicelo ezifuna ukuchaneka kunye nezixhobo ezisezantsi zokukhuhlana.
Isicelo
I-POM, ekwabizwa ngokuba yi-acetal okanye i-Delrin, yimathiriyeli eguquguqukayo ye-thermoplastic esetyenziswa kwiintlobo ngeentlobo zezicelo.Iimpawu zayo ezizodwa ziyenza ilungele ukwenza iigiya kunye neebheringi kwiinkqubo zoomatshini.Amacandelo eemoto, afana namacandelo enkqubo yamafutha kunye ne-trim yangaphakathi, nawo ayazuza ekomeleleni nasekuxhathiseni kwePOM.Ukongeza, iipropathi ezigqwesileyo zokufakelwa kombane zePOM ziyenza ilungele ukusetyenziswa kwizihlanganisi zombane.Okokugqibela, amandla ePOM kunye nobomi obude buyenza ibe lolona khetho lukhethwayo lokuvelisa iimpahla zabathengi ezinje ngeeziphu, iithoyi kunye nempahla yasekhitshini.
Amandla
Izinto eziphathekayo zinamandla amangalisayo kwaye ziyakwazi ukumelana namandla amakhulu omatshini.Inika intshukumo egudileyo kunye nokukhuhlana okuncinci kwaye iyaxhathisa ukunxiba.Igcina imilo yayo kunye nemilinganiselo kuzo zonke iimeko, iqinisekisa ukuzinza.Ukongezelela, iyamelana nemiphumo yeekhemikhali kwaye inokumelana nokuvezwa kwezinto ezahlukeneyo ngaphandle kokuthotywa.
Ubuthathaka
Izinto eziphathekayo zinokumelana okulinganiselweyo kwimitha ye-UV kwaye ngoko ke iyakwazi ukonakala ngexesha lokuvezwa ixesha elide elangeni.Kwakhona, ithambekele ekucinezeleni iintanda phantsi kweemeko ezithile.

Ulwazi lwesayensi oludumileyo malunga nePOM
I-POM (i-Polyoxymethylene), eyaziwa ngokuba yi-acetal, yiplastiki yobunjineli esebenza kakhulu.Yi-semi-crystalline thermoplastic enika amandla omatshini abalaseleyo, ukuqina, kunye nokuzinza komda.I-POM iqhele ukusetyenziswa kwiindawo ezichanekileyo, njengeegiya, iibheringi, kunye nezinto zemoto.
I-POM ine-coefficient ephantsi ye-friction, eyenza ukuba ifaneleke kwizicelo ezifuna ukugqoka okuphantsi kunye nokuxhatshazwa.Inokumelana kakuhle neekhemikhali, i-solvents, kunye namafutha, okwenza ukuba ilungele ukusetyenziswa kwimizi-mveliso yeemoto kunye neekhemikhali.I-POM nayo ineempawu ezilungileyo zokugquma umbane kwaye inokumelana namaqondo obushushu aphezulu.
I-POM ifumaneka kwiintlobo ezimbini eziphambili: i-homopolymer kunye ne-copolymer.I-Homopolymer POM inikezela ngamandla omatshini aphezulu kunye nokuqina, ngelixa i-POM ye-copolymer inikezela ukuxhathisa okungcono ekuthotyweni kwe-thermal kunye nokuhlaselwa kweekhemikhali.
