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

I-Acrylonitrile butadiene styrene (ABS) (ifomula yekhemikhali (C8H8)x·​(C4H6)y·​(C3H3N)z) yipolymer eqhelekileyo ye-thermoplastic.Ubushushu beglasi yayo yokutshintsha bumalunga ne-105 °C (221 °F).I-ABS yi-amorphous kwaye ngoko ayinayo indawo yokunyibilika yokwenyani.I-Polytetrafluoroethylene (PTFE) yi-synthetic fluoropolymer ye-tetrafluoroethylene enezicelo ezininzi.Elona gama lebhrendi laziwayo le-PTFE-based formulas yipolymer yiChemours.I-Chemours sispin-off ye-DuPont Co., eyafumanisa ikhompawundi ngo-1938.

Eyona mpahla ibalulekileyo yoomatshini be-ABS kukuxhathisa impembelelo kunye nokuqina.Iindidi ezahlukeneyo zokuguqulwa zinokwenziwa ukuphucula ukuxhathisa impembelelo, ukuqina, kunye nokumelana nobushushu.Ukuxhatshazwa kwempembelelo kunokwandiswa ngokunyusa umlinganiselo we-polybutadiene ngokumalunga ne-styrene kunye ne-acrylonitrile, nangona oku kubangela utshintsho kwezinye iipropati.Ukumelana neempembelelo akuwi ngokukhawuleza kumaqondo obushushu aphantsi.Ukuzinza phantsi komthwalo kuhle kakhulu kunye nemithwalo elinganiselwe.Ngaloo ndlela, ngokutshintsha imilinganiselo yamacandelo ayo, i-ABS inokulungiswa kumabakala ahlukeneyo.Iindidi ezimbini eziphambili inokuba yi-ABS ye-extrusion kunye ne-ABS yokubumba inaliti, emva koko ukuchasana kwempembelelo ephezulu naphakathi.Ngokubanzi i-ABS inokuba neempawu eziluncedo kuluhlu lobushushu ukusuka ku-−20 ukuya kuma-80 °C (−4 ukuya kwi-176 °F).

I-PTFE yipolymer ye-thermoplastic, eqinileyo emhlophe kwiqondo lobushushu begumbi, kunye noxinano malunga ne-2200 kg/m3.Ngokutsho kweDuPont, indawo yayo yokunyibilika ngama-600 K (327 °C; 620 °F).Igcina amandla aphezulu, ukuqina kunye nokuzithambisa kumaqondo obushushu asezantsi ukuya kutsho ku-5 K (−268.15 °C; -450.67 °F), kunye nokuguquguquka okulungileyo kumaqondo obushushu angaphezu kwe-194 K (−79 °C; -110 °F).I-PTFE izuza iipropati zayo kwisiphumo esidityanisiweyo sebhondi ye-carbon-fluorine, njengazo zonke ii-fluorocarbons.Ekuphela kweekhemikhali ezaziwa ukuba zichaphazela ezi bhondi zekhabhoni-fluorine zizinyithi ezisebenza kakhulu njengeentsimbi zealkali, kwaye kumaqondo obushushu aphezulu ngokunjalo nezinyithi ezifana nealuminiyam nemagnesium, kunye neearhente zokuthambisa ezifana nexenon difluoride kunye necobalt(III) fluoride.
