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

I-Acrylonitrile butadiene styrene (ABS) (ifomula yamakhemikhali (C8H8)x·(C4H6)y·​(C3H3N)z) i-polymer ye-thermoplastic evamile.Izinga lokushisa lokushintsha kwengilazi yalo licishe libe ngu-105 °C (221 °F).I-ABS i-amorphous ngakho-ke ayinakho ukuncibilika kweqiniso.I-Polytetrafluoroethylene (PTFE) iyi-fluoropolymer yokwenziwa ye-tetrafluoroethylene enezinhlelo zokusebenza eziningi.Igama lomkhiqizo elaziwa kakhulu lamafomula asekelwe ku-PTFE yi-polymer by Chemours.I-Chemours iyi-spin-off ye-DuPont Co., eyathola i-compound ngo-1938.

Izakhiwo ezibaluleke kakhulu zemishini ye-ABS ukumelana nomthelela kanye nokuqina.Izinguquko ezihlukahlukene zingenziwa ukuze kuthuthukiswe ukumelana nomthelela, ukuqina, nokumelana nokushisa.Ukumelana nomthelela kungakhuliswa ngokwandisa izilinganiso ze-polybutadiene ngokuphathelene ne-styrene kanye ne-acrylonitrile, nakuba lokhu kubangela izinguquko kwezinye izakhiwo.Ukumelana nomthelela akuwi ngokushesha emazingeni okushisa aphansi.Ukuzinza ngaphansi komthwalo kuhle kakhulu ngemithwalo elinganiselwe.Ngakho-ke, ngokushintsha izilinganiso zezingxenye zayo, i-ABS ingalungiswa emabangeni ahlukene.Izigaba ezimbili ezinkulu kungaba yi-ABS ye-extrusion kanye ne-ABS yokubumba umjovo, bese kuba ukumelana nomthelela ophezulu naphakathi.Ngokuvamile i-ABS ingaba nezici eziwusizo phakathi kwebanga lokushisa elisuka ku-−20 ukuya ku-80 °C (−4 kuya ku-176 °F).

I-PTFE i-polymer ye-thermoplastic, eqinile emhlophe ekamelweni lokushisa, enokuminyana okungaba ngu-2200 kg/m3.Ngokusho kweDuPont, indawo yayo yokuncibilika ingu-600 K (327 °C; 620 °F).Igcina amandla aphezulu, ukuqina kanye nokuzithambisa emazingeni okushisa aphansi kuze kufike ku-5 K (−268.15 °C; -450.67 °F), futhi ikwazi ukuguquguquka kahle emazingeni okushisa angaphezu kuka-194 K (−79 °C; -110 °F).I-PTFE izuza izakhiwo zayo kusukela kumphumela ohlanganisiwe webhondi ye-carbon-fluorine, njengoba kwenza wonke ama-fluorocarbons.Amakhemikhali okuwukuphela kwawo aziwa ukuthi athinta la mabhondi e-carbon-fluorine ayizinsimbi ezisebenza kakhulu njengezinsimbi ze-alkali, futhi emazingeni okushisa aphezulu nezinsimbi ezinjenge-aluminium ne-magnesium, nama-fluorinating agents afana ne-xenon difluoride ne-cobalt(III) fluoride.
