Sebenzisa ezi ndlela zisi-7 ukuchonga iTPE kunye neTPU!

I-TPE ithetha ngokubanzi igama eliqhelekileyo kuzo zonke ii-elastomers ze-thermoplastic.Ihlelwa ngolu hlobo lulandelayo:

Kodwa into ebizwa ngokuba yi-TPE ngumxube we-SEBS / SBS + PP + ioli ye-naphthenic + calcium carbonate + abancedisi.Ikwabizwa ngokuba yiplastiki ethambileyo yokusingqongileyo kwishishini, kodwa ngamanye amaxesha ibizwa ngokuba yi-TPR (idla ngokubizwa ngokuba yiZhejiang naseTaiwan)).I-TPU, ebizwa ngokuba yi-polyurethane, ineentlobo ezimbini: uhlobo lwe-polyester kunye nohlobo lwe-polyether.

I-TPE kunye ne-TPU zombini zizixhobo ze-thermoplastic ezine-rubber elasticity.Izinto ze-TPE kunye ne-TPU ezinobunzima obufanayo ngamanye amaxesha kunokuba nzima ukwahlula phakathi kwe-TPE kunye ne-TPU ngokujonga nje ngeliso lenyama.Kodwa ngokuqala ngeenkcukacha, sisenako ukuhlalutya umahluko kunye nomahluko phakathi kwe-TPE kunye ne-TPU kwiinkalo ezininzi.

1.Ukungafihli

Ukungafihli kwe-TPU kungcono kunokwe-TPE, kwaye akukho lula ukunamathela njenge-TPE ecacileyo.

2. Umlinganiselo

Umlinganiselo we-TPE uhluka ngokubanzi, ukusuka kwi-0.89 ukuya kwi-1.3, ngelixa i-TPU isuka kwi-1.0 ukuya kwi-1.4.Enyanisweni, ngexesha lokusetyenziswa kwazo, zibonakala ngokuyintloko ngendlela yokudibanisa, ngoko ke ubunzima obuthile butshintsha kakhulu!

3.Ukumelana neoli

I-TPU inokumelana ne-oyile elungileyo, kodwa kunzima ukuba i-TPE ikwazi ukumelana ne-oyile.

4.Emva kokutshisa

I-TPE inevumba elimnandi xa utshisa, kwaye umsi ovuthayo mncinci kwaye ulula.Ukutsha kweTPU kunevumba elithile elirhabaxa, kwaye kukho isandi esincinci sokudubula xa utshisa.

5.Iimpawu zeMechanical

I-TPU's elasticity kunye ne-elastic recovery properties (i-flexion resistance kunye ne-creep resistance) ingcono kune-TPE.

Esona sizathu siphambili kukuba ulwakhiwo lwempahla ye-TPU sisakhiwo se-polymer homogeneous kwaye sesodidi lwe-polymer resin.I-TPE yi-alloy material ene-multi-phase structure edityanisiweyo yi-multi-component blend.

Ukusetyenzwa kobunzima obuphezulu be-TPE kuthanda ukuguquguquka kwemveliso, ngelixa i-TPU ibonisa ukuqina okugqwesileyo kuzo zonke izintlu zobunzima, kwaye imveliso akulula ukuyikhubaza.

6.Ukumelana nobushushu

I-TPE yi -60 degrees celcius ~ 105 degrees celcius, iTPU yi -60 degrees Celsius ~ 80 degrees Celsius.

7.Ukubonakala kunye nokuziva

Kwezinye iimveliso ezigqithisiweyo, iimveliso ezenziwe nge-TPU zinemvakalelo erhabaxa kunye nokuxhathisa okunamandla kwi-friction;ngelixa iimveliso ezenziwe nge-TPE zinemvakalelo ethambileyo nethambileyo kunye nokusebenza okubuthathaka.

Ukushwankathela, zombini i-TPE kunye ne-TPU zizinto ezithambileyo kwaye zinerabha elungileyo.Xa kuthelekiswa, i-TPE ibalasele ngakumbi ngokwemiqathango yokuthuthuzela okubambekayo, ngelixa i-TPU ibonisa ukuqina okugqwesileyo kunye nokomelela.
