"Turi" yana nufin adadin ƙarfin da ake buƙata don nakasar naúrar abu; "Sauƙin" yana nufin adadin nakasar abu a ƙarƙashin ƙarfin naúrar. Girman "tauri" ɗin, ƙarancin nakasar abu yana iya faruwa; girman "sauƙin" ɗin, mafi yawan saurin nakasar abu. Kayan da ke da kyakkyawan tauri yana da laushi, kuma tsawaitar tensile a lokacin karyewa da ƙarfin tasiri sun fi girma, yayin da tauri, ƙarfin tensile da modulus na roba sun fi ƙanƙanta.
Kamar yadda aka gani daga bayanin da ke sama, tauri da tauri akasin haka ne, amma ga robobi da aka gyara suna dogara ne akan juna. Misali, lokacin da robobi da aka ƙarfafa da fiberglass suka ƙara tauri, ƙarfin tauri da ƙarfin tasiri na iya ƙaruwa.
Yadda ake inganta ƙarfin filastik?
An gano cewa ƙara taurin resin matrix zai iya inganta tasirin taurin robobi masu tauri.
Akwai hanyoyi da yawa na tauri, kamar ƙara nauyin kwayoyin halitta na matrix resin don rage rarraba nauyin kwayoyin halitta, ko kuma sarrafa lu'ulu'u, lu'ulu'u, girman lu'ulu'u da siffar lu'ulu'u don inganta ƙarfinsu.
Yadda ake bambance sinadarin filastik da ake amfani da shi akai-akai?
• An ƙara taurare roba (roba elastomer)
EPR (binary ethylene-propylene), EPDM (EPDM), robar butadiene (BR), robar halitta (NR), robar isobutene (IBR), robar nitrile (NBR), da sauransu. Ya dace da duk wani gyara na taurare resin filastik;
• Ana ƙara taurare elastomers na thermoplastic
SBS, SEBS, POE, TPO, TPV, da sauransu. Don ƙarfafa polyolefin ko resin mara polar, don polyester, polyamide da sauran polymers waɗanda ke ɗauke da ƙungiyoyin aiki na polar, buƙatar ƙara masu dacewa;
• Copolymer mai ƙarfi da harsashi mai ƙarfi da kuma terpolymer mai amsawa
ACR (acrylate), MBS (methyl acrylate-butadiene-styrene copolymer), PTW (ethylene-butyl acrylate-glycidyl methacrylate copolymer), E-MA-GMA (ethylene-methyl acrylate-glycidyl methacrylate copolymer), da sauransu. Ana amfani da shi don injiniyan robobi da kuma taurarewar polymer mai jure zafi mai yawa;
• Yana ƙarfafawa ta hanyar haɗa robobi masu ƙarfi
PP/PA, PP/ABS, PA/ABS, HIPS/PPO, PPS/PA, PC/ABS, PC/PBT, da sauransu. Fasahar polymer alloy hanya ce mai mahimmanci ta shirirobobi masu ƙarfi na injiniya.
• Sauran hanyoyin da za a iya tauri
Ƙara tauri ga ƙwayoyin nano (kamar nano-cacO3), ƙara tauri ga resin sarin (Dupont metal ionomer), da sauransu.
