Uke wezwa ukuthi ezinye izitikha zingahlala zinamathele ngemva kokuwashwa nokususwa izikhathi ezimbalwa?Ngokuvamile izitikha ezinjengezitikha ze-vinyl, izitikha zephepha nezitikha ezikhukhumele zizoshiya ingcina yeglue noma i-viscosity iba buthakathaka ngemva kokuyikhipha izikhathi eziningana.Manje sizoklelisa izici nokuqhathanisa kwalezi zinhlobo ezi-3 zezitikha ezingawasheka, zikhipheke, zigaywe kabusha.Zisetshenziswa kakhulu ezinkundleni zokudlala zamabhuku ezitikha zezingane noma izindawo ezicwebezelayo ze-DIY, lezo zitikha zeSilicone, izitika ze-TPU nezitikha ze-TPE sizibize.
Izitika ze-silicone ezifana namagama azo zenziwe nge-silicone.I-Silicone ayigcini nje ngokuba nokuthinta okuthambile futhi ivumelana nemvelo kodwa inezici zamakhemikhali ezizinzile ezenza izitika ze-silicone zikwazi ukumelana nezinga lokushisa eliphezulu.Inganamathela kunoma iyiphi indawo ecwebezelayo, njengamafasitela, izibuko, izincwadi zezingane, njll. Ugqinsi lwezitikha ze-silicone zingenziwa ngendlela oyifisayo ukusuka ku-0.1mm ukuya ku-1.0mm, kokubili umbala osobala nomhlophe usekelwe.Ngenxa yokukhuphuka kwentengo ye-silicone eminyakeni yamuva nje, isitikha se-silicone sesibize kakhulu phakathi kwalezi zintathu.
I-PU iyi-elastomer eguquguquka kakhulu enezici ezihlukile, ukuthinta okuthambile futhi ukushuba kwayo kungenziwa ngokwezifiso.Iglue eyengeziwe ingase yengezwe ezintweni ze-PU ngesikhathi sokucutshungulwa kwezitikha, okwenza izitika ze-PU zisetshenziswe kunoma iyiphi indawo ecwebezelayo ne-matte.Uma kuqhathaniswa nezitikha ze-silicone, ukuzinza kwayo kwamakhemikhali kubi kancane futhi ayifanele indawo yokushisa engaphezulu kuka-70℃.Isitika se-PU sithatha indawo enhle uma ungenaso isabelomali esanele sezitikha ze-silicone.
Ama-Thermoplastic elastomers (TPE), uhlobo lwesakhiwo samangqamuzana anikeza i-TPE izakhiwo ezinwebekayo eziphezulu.Uma ubheka ukubukeka nomsebenzi oyisisekelo, awukho umehluko omkhulu phakathi kwe-TPE ne-PU.Ngenxa yezinto ezingavuthiwe ze-PU ezisebenziseka kabusha futhi izindleko zayo eziphezulu kune-TPE, i-TPE izoba indawo enhle ye-PU.
Ukuqhathanisa
Uma udinga lezi zitikha zomlingo esandleni ukuze uhlole futhi uhlole ikhwalithi, sicela ukhululeke ukusithinta.
