Acrylonitrile butadiene styrene (ABS) vs Polymer PTFE/FEP Machining

Acrylonitrile butadiene styrene (ABS) (kemikari formula (C8H8)x·(C4H6)y·​(C3H3N)z) inowanzoitika thermoplastic polima.Tembiricha yaro yekuchinja kwegirazi ingangoita 105 °C (221 °F).ABS is amorphous saka haina chokwadi chekunyunguduka.Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer ye tetrafluoroethylene ine maapplication akawanda.Inonyanya kuzivikanwa zita remhando yePTFE-yakavakirwa mafomula ndeye polymer neChemours.Chemours is spin-off yeDuPont Co., iyo yakawana komboni iyi muna 1938.

Iwo akanyanya kukosha emuchina zvimiro zveABS ndezvekupikisa kuramba uye kuoma.Yakasiyana-siyana magadzirirwo anogona kuitwa kuti avandudze kukanganisa kuramba, kuomarara, uye kupisa kupisa.Iko kukanganisa kupikisa kunogona kukwidziridzwa nekuwedzera zviyero zve polybutadiene maererano ne styrene uye zvakare acrylonitrile, kunyange izvi zvichikonzera shanduko mune zvimwe zvinhu.Impact resistance haisi kudonha nekukurumidza pakudzika kwakadzika.Kugadzikana pasi pemutoro kwakanakisa nemitoro shoma.Saka, nekushandura zviyero zvezvikamu zvayo, ABS inogona kugadzirirwa mumakiredhi akasiyana.Mapato maviri makuru anogona kunge ari ABS yeextrusion uye ABS yekuumba jekiseni, yozokwira uye yepakati kukanganisa kuramba.Kazhinji ABS yaizove nehunhu hunobatsira mukati metembiricha kubva −20 kusvika 80 °C (-4 kusvika 176 °F).

PTFE inonzi thermoplastic polymer, iri chena yakasimba patembiricha yemumba, ine density inoita 2200 kg/m3.Sekureva kweDuPont, kunyungudika kwayo i600 K (327 °C; 620 °F).Inochengetedza simba repamusoro, kuomarara uye kuzvigadzika patembiricha yakaderera kusvika pa5 K (−268.15 °C; -450.67 °F), uye kuchinjika zvakanaka patembiricha iri pamusoro pe194 K (-79 °C; -110 °F).PTFE inowana zvivakwa zvayo kubva paaggregate mhedzisiro yecarbon-fluorine bond, sezvinoita ese mafluorocarbons.Iwo ega makemikoro anozivikanwa kukanganisa aya kabhoni-fluorine zvisungo simbi dzinoshanda zvakanyanya senge alkali simbi, uye pakupisa kwepamusoro zvakare simbi sealuminium nemagnesium, uye fluorinating agents senge xenon difluoride uye cobalt (III) fluoride.

Kuenzaniswa kweAcrylonitrile butadiene styrene (ABS) uye Polymer PTFE/FEP Property Values

Material Applications

Acrylonitrile butadiene styrene (ABS)ipes uye Fittings;Miviri yevharuvhu, zvinhu zvekushandisa zvekushandisa.

polymer PTFE/FEP: Cabling mhinduro; Asina lubricated bearings; O-mhete; Zvisimbiso; Capacitors; Semiconductor kugadzira; Tembiricha yepamusoro yemagetsi zvikamu; Gaskets; Valve components.

Material Properties

Acrylonitrile butadiene styrene (ABS): Yakanakisa simba rekuita; Yakanaka yekugadzira uye machining zvivakwa; Yakanakisa aesthetic zvivakwa; Yakanaka makemikari kuramba; Michina iri nyore; Yakaderera kupisa conductivity; Corrosion uye abrasion inodzivirira; Yakaderera co-efficient yekukwesha.

Polymer PTFE / FEP: Yakanakisa dielectric zvivakwa; Kusabatika kune akawanda makemikari; Kupisa kwakanyanya uye makemikari kuramba; Yakanyanya kuderera coeffiecient yekukwesha; Yakanakisa nemwaranzi kuramba; Zero mwando kunyura; Zvishoma kusanzwa kune simba frequency; Machinability.
