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

Acrylonitrile butadiene styrene (ABS) ( agbekalẹ kemikali (C8H8) x · (C4H6) y· (C3H3N) z) jẹ polymer thermoplastic ti o wọpọ.Iwọn otutu iyipada gilasi rẹ jẹ isunmọ 105 °C (221 °F).ABS jẹ amorphous ati nitorina ko ni aaye yokuro otitọ.Polytetrafluoroethylene (PTFE) jẹ fluoropolymer sintetiki ti tetrafluoroethylene ti o ni awọn ohun elo lọpọlọpọ.Orukọ ami iyasọtọ ti o mọ julọ ti awọn agbekalẹ orisun-PTFE jẹ polymer nipasẹ Chemours.Chemours jẹ iyipo-pipa ti DuPont Co., eyiti o ṣe awari akopọ ni ọdun 1938.

Awọn ohun-ini ẹrọ ti o ṣe pataki julọ ti ABS jẹ resistance ikolu ati lile.Orisirisi awọn iyipada le ṣee ṣe lati mu ilọsiwaju ikolu, lile, ati resistance ooru.Agbara ipa le ṣe alekun nipasẹ jijẹ awọn ipin ti polybutadiene ni ibatan si styrene ati tun acrylonitrile, botilẹjẹpe eyi nfa awọn ayipada ninu awọn ohun-ini miiran.Idaabobo ikolu ko ni ṣubu ni kiakia ni awọn iwọn otutu kekere.Iduroṣinṣin labẹ fifuye jẹ o tayọ pẹlu awọn ẹru to lopin.Nitorinaa, nipa yiyipada awọn ipin ti awọn paati rẹ, ABS le ṣetan ni awọn onipò oriṣiriṣi.Awọn ẹka pataki meji le jẹ ABS fun extrusion ati ABS fun mimu abẹrẹ, lẹhinna giga ati resistance resistance alabọde.Ni gbogbogbo ABS yoo ni awọn abuda to wulo laarin iwọn otutu lati -20 si 80 °C (-4 si 176 °F).

PTFE jẹ polymer thermoplastic, eyiti o jẹ funfun ti o lagbara ni iwọn otutu yara, pẹlu iwuwo ti o to 2200 kg/m3.Gẹgẹbi DuPont, aaye yo rẹ jẹ 600 K (327 °C; 620 °F).O ṣetọju agbara giga, lile ati lubrication ti ara ẹni ni awọn iwọn otutu kekere si 5 K (-268.15 °C; -450.67 °F), ati irọrun ti o dara ni awọn iwọn otutu ju 194 K (-79 °C; -110 °F).PTFE gba awọn ohun-ini rẹ lati ipa apapọ ti awọn iwe ifowopamọ carbon-fluorine, bii gbogbo awọn fluorocarbons.Awọn kemikali nikan ti a mọ lati ni ipa lori awọn ifunmọ carbon-fluorine wọnyi jẹ awọn irin ti o ni ifaseyin pupọ bi awọn irin alkali, ati ni awọn iwọn otutu ti o ga julọ tun iru awọn irin bi aluminiomu ati iṣuu magnẹsia, ati awọn aṣoju fluorinating gẹgẹbi xenon difluoride ati koluboti (III) fluoride.
