Ngaba ukhe weva ukuba ezinye izincamathelisi zihlala zincangathi emva kokuba zihlanjiwe kwaye zasuswa amatyeli amaninzi?Ngokwesiqhelo izincamathelisi ezinjengezincamathelisi zevinyl, izincamathelisi zephepha kunye nezincamathelisi ezikhukhumeleyo ziya kuyishiya iglu okanye i-viscosity ibe buthathaka emva kokuyisusa izihlandlo ezininzi.Ngoku siza kudwelisa iimpawu kunye nothelekiso lwezi ntlobo zi-3 zezitikha ezinokuthi zihlambeke, zisuswe, zenziwe ngokutsha.Zisetyenziswa ngokubanzi kwiindawo zokudlala zeencwadi ezincamathelayo zabantwana okanye iindawo ezimenyezelayo zeDIY, sazibiza ezo zincamathelisi zeSilicone, izincamathelisi zeTPU kunye nezincamathelisi zeTPE.
Izitikha zeSilicone ezifana namagama azo zenziwe nge-silicone.I-Silicone ayinayo nje into yokubamba ethambileyo kwaye i-eco-friendly kodwa ineempawu ezizinzileyo zeekhemikhali ezivumela izitikha ze-silicone ukuba zichase ubushushu obuphezulu.Iyakwazi ukuncamathela kuyo nayiphi na indawo ekhazimlayo, njengeefestile, izibuko, iincwadi zezingane, njl njl. Ubukhulu bezitikha ze-silicone zingenziwa ngokwezifiso ukusuka kwi-0.1mm ukuya kwi-1.0mm, zombini ezicacileyo kunye nombala omhlophe zixhaswa.Ngenxa yokunyuka kwexabiso le-silicone kwiminyaka yakutshanje, isincamathelisi se-silicone siye sabiza kakhulu phakathi kwezi zintathu.
I-PU yi-elastomer eguquguqukayo kakhulu eneempawu ezizodwa, ichukumisa ithambile kwaye ubukhulu bayo bunokwenziwa ngokwezifiso.Iglu eyongeziweyo inokongezwa kwimathiriyeli ye-PU ngexesha lokusetyenzwa kwezincamathelisi, nto leyo eyenza ukuba izincamathelisi ze-PU zisetyenziswe nakuwuphi na umphezulu omenyezelayo kunye ne-matte.Xa kuthelekiswa nezitikha ze-silicone, ukuzinza kwayo kweekhemikhali kubi kancinci kwaye ayifanelekanga kumphezulu wobushushu obungaphezulu kwe-70℃.Isincamathelisi sePU siyindawo elungileyo ukuba akunabhajethi eyaneleyo yezincamathelisi zesilicone.
I-Thermoplastic elastomers (TPE), uhlobo lwesakhiwo sabo semolekyuli inika i-TPE iipropathi ezinwebekayo eziphezulu.Ukujonga imbonakalo kunye nomsebenzi osisiseko, akukho mahluko kakhulu phakathi kwe-TPE kunye ne-PU.Ngenxa yezinto ezikrwada ze-PU ezinokuphinda zisetyenziswe kwaye iindleko zayo eziphezulu kune-TPE, i-TPE iya kuba yindawo efanelekileyo ye-PU.
Ukuthelekisa
Ukuba ufuna ezi zincamathelisi zomlingo esandleni ukuze uthathe uvavanyo kwaye ujonge umgangatho, nceda uzive ukhululekile ukuqhagamshelana nathi.
