Uhlobo lwePolyether TPU-M series/ Iigranule zePolycarbonate/Izinto zeplastiki ezikrwada/Ixabiso lezinto zeplastiki ezikrwada
malunga ne-TPU
I-thermoplastic polyurethane elastomer (TPU) luhlobo lwe-elastomer enokwenziwa iplastiki ngokufudumeza nokunyibilikisa nge-solvent. Ineempawu ezibalaseleyo ezibanzi ezifana namandla aphezulu, ukuqina okuphezulu, ukumelana nokuguguleka kunye nokumelana neoyile. Isebenza kakuhle ekucubunguleni kwaye isetyenziswa kakhulu kushishino lokhuselo lwesizwe, lwezonyango, lokutya nakwamanye amashishini. I-Thermoplastic Polyurethane ineentlobo ezimbini: uhlobo lwe-polyester kunye nohlobo lwe-polyether, amasuntswana amhlophe angahleliwe okanye ajikelezayo, kwaye uxinano yi-1.10~1.25g/cm3. Uxinano oluhambelanayo lohlobo lwe-polyether luncinci kunolo lohlobo lwe-polyester. Ubushushu botshintsho lweglasi lohlobo lwe-polyether yi-100.6~106.1℃, kwaye ubushushu botshintsho lweglasi lohlobo lwe-polyester yi-108.9~122.8℃. Ubushushu bokubhitya kohlobo lwe-polyether kunye nohlobo lwe-polyester buphantsi kune--62℃, kwaye ukumelana nobushushu obuphantsi kohlobo lwe-polyether kungcono kunolo lohlobo lwe-polyester. Iimpawu ezibalaseleyo ze-polyurethane thermoplastic elastomers kukumelana nokuguguleka okugqwesileyo, ukumelana ne-ozone egqwesileyo, ubulukhuni obuphezulu, amandla aphezulu, ukuthamba okuhle, ukumelana nobushushu obuphantsi, ukumelana neoyile elungileyo, ukumelana neekhemikhali kunye nokumelana nokusingqongileyo. Ukuzinza kwe-hydrolytic kohlobo lwe-ester kuphezulu kakhulu kunohlobo lwe-polyester.

Ukuphatha kunye nokugcina
1. Kuphephe ukuphefumla umsi kunye nomphunga osebenza ngobushushu
2. Izixhobo zokuphatha oomatshini zinokubangela ukwakheka kothuli. Kuphephe ukuphefumla uthuli.
3. Sebenzisa iindlela ezifanelekileyo zokumisa umhlaba xa uphatha le mveliso ukuze uphephe ukutshaja ngombane
4. Iipellets eziphantsi zingaba zityibilizi kwaye zibangele ukuwa
Iingcebiso zokugcina: Ukuze ugcine umgangatho wemveliso, gcina imveliso kwindawo epholileyo neyomileyo. Yigcine kwisikhongozeli esivalwe kakuhle.
