其實是這樣的,在潤滑劑中,分為三種:lubricant, anti-adherent, glidant
三者的英文敘述我稍微打上來
lubricant:to reduce the friction during compression
anti-adherent:avoid sticking to die walls and picking by punches
glidant:improve the flow of property of materials/granules
所以,如果照題目來看「...降低....黏合....」,那應該要選擇分在anti-adherent底下的talc
順帶一提,果仁大的glidant舉例中,其實talc不該被歸為此類,glidant在國考中出現過的是 膠性矽土(fumed-silicon)
不過在原文中也提到talcum serves all the three functions(潤滑、抗黏著、滑動), most of the manufactures still use only talcum for lubricant, ...
