Yintoni umahluko phakathiI-TPUkunye ne-pu?

I-TPU (POLONURETHAGE ELASTAMER)

I-TPU (iTermoplastic Polyreurthane Elastomer)Ngaba iintlobo zeplastiki ezivelayo. Ngenxa yokuxhaphaka kwayo okuhle, ukuxhathisa kwemozulu, kunye nokulunga kokusingqongileyo, i-TPU isetyenziswa ngokubanzi kumashishini ahambelana noko, imibhobho, iifilimu, iintambo, kunye neentambo.

I-Polyurethane Thermoplastic Elastomer, ekwabizwa ngokuba yi-thermoplastic polymoplane iraliyo, ifinyezwe njenge-TPU, luhlobo lwe (AB) i-N-Vib Gool Polymer. Isisindo esiphezulu semolekyuli (i-1000-6000) polyester okanye i-polyeether, kwaye b yidiol ene-2-12 eqondile iathom ye-carbon. Isakhiwo sekhemikhali phakathi kwe-ab ye-ab lidisoclonanate, idla ngokunxulunyaniswa yi-MDI.

I-Thermoplastic Polyurethane i-polymorthane ixhomekeke kwi-Intermolecular Hydrogen Holl okanye i-comp-cross-lickes ephakathi kwamakhonkco macromolecular, kwaye ezi zakhiwo zidibanisayo zixhaphakile okanye zinciphise ubushushu okanye ukunciphisa ubushushu. Kwimo etyhidiweyo okanye isisombululo, amandla angenasiphako oyenze buthathaka, kwaye emva kokupholisa okanye ukucocwa kwe-interven okanye i-Solvent Arcent Annences eqokelelene, ukubuyisela iipropathi zesiseko sokuqala.

I-Polyurethane Thertolistic ElastorsInokubekwa kwiindidi ezimbini: i-polyester kunye nePolyteer, kunye ne-whiterem engaqhelekanga okanye amasuntswana e-slowcalar kunye noxinano lwe-1.10-125. Uhlobo lwePolyet lunexesha eliphantsi lohlobo olusezantsi kunohlobo lwePolyester. Iqondo lokushisa leglasi ye-Polyether Tect liyi-100.6-106.1 Iqondo lobushushu leBrittletlet Tepet kunye nohlobo lwePolyester lingaphantsi kwe -62 ℃, ngelixa ukuchasana nobushushu obuphantsi kohlobo lwe-ether lubhetele kunohlobo lwe-polyester.

Iimpawu ezibalaseleyo zePolymoverist Elastovemers zinxibe ngokuchasene nokunganyangeki kwe-ozone egqwesileyo, ubunzima obungaphezulu, ukungavisisani kweoyile esezantsi, ukumelana nezoyile, kunye nokuxhathisa kwezendalo. Kwindawo ezinomswakama, uzinzo lwe-hydrolysis ye-polyerther esters ezigqitha kakhulu ezodidi lwePolyester.

I-Polyurethane Thertoplamers ye-Elastolimes ayinatyhefu kwaye ingenabubi, inyibilikiswe kwimizila ye-metcyl, i-Diorahy-Acetate, i-Diorahy-Acetate, i-Demllone, kunye ne-acetone kwindawo efanelekileyo. Babonisa imeko engenamibala kunye nendawo ebonakalayo kwaye banozinzo oluhle lokugcina.
