Iimpawu zeedayi ezisasazwayo:
Ngokungafaniyo nezinye iintlobo zedayi, iidayi ezisasazwayo azinyibiliki kangako emanzini kunezinye iidayi ezinjengeedayi zeasidi. Ke ngoko, iidayi ezisasazwayo zisetyenziswa kakhulu ekudayeni izisombululo zebhafu.Tamol NNisebenza kakuhle xa inkqubo yokudaya iqhutywa kumaqondo obushushu aphezulu. Ngokukodwa, izisombululo ezijikeleze i-120 ° C ukuya kwi-130 ° C zinika ukusebenza ngokufanelekileyo ukusasaza idayi, zizenze zisasazwe ngokulinganayo kwaye zijonge ngamehlo, ngelixa.Tamol NNkunokubangela ukungalingani kunye nokuncipha kwemibala yombala kumaqondo obushushu asezantsi.
Zeziphi izinto ezisetyenziselwa zona iidayi ezisasazwayo?Tamol NN
Ngenxa yeempawu zazo zekhemikhali kunye nendlela yokuziphatha echazwe ngasentla, iidayi ezisasazwayo zidla ngokusetyenziselwa ukudaya iintsinga zokwenziwa, ezinjengepolyester, inayiloni, iacrylic, kunye neacetate. Uninzi lweentlobo ze-polyester zi-hydrophobic kwaye azikho iipropathi ze-ionic, zibenza baphantse bangakwazi ukufaka imibala kunye nantoni na ngaphandle kokusasaza idayi.
Ukongezelela, iifayili ze-polyester azinandisi kumaqondo okushisa aqhelekileyo naxa zicwiliswa kwindawo yokuhlambela idayi, okwenza kube nzima ukuba iimolekyuli zedayi zidibanise kunye nezinto. Nakwiqondo lokubilisa (100°C), ukudaywa kwepolyester kuneengxaki.
Ngoko ke, xa udaya i-polyester, iidayi ezisasazwayo zisetyenziselwa ukudaya izisombululo zokuhlambela kumaqondo okushisa angama-20 ukuya kuma-30 aphezulu ngaphezu kwendawo yokubilisa yokudaya izisombululo zokuhlambela. Iidayi ezisasazwayo ziyaziwa ngokugcina ingqibelelo yazo yeemolekyuli kumaqondo obushushu aphezulu afunekayo ekufaka imibala kwipolyester. Ngesizathu esifanayo, iidayi ezisasazwayo zisetyenziselwa ukudaya iipolyester, zikwasetyenziselwa ukudaya ezinye izinto ezingezizo i-ionic synthetic. Inyaniso yokuba iidayi ezisasazwayo azinayo i-cationic okanye i-anionic tendencies mhlawumbi ipropathi ephawulekayo yokusabalalisa idayi.
Iidayi ezisasazwayo zisenokusetyenziswa kwiireyini kunye neeplastiki ngeenjongo zokufaka imibala kumphezulu kunye nobubanzi.
