Uhlobo lwe-Polyether TPU-M uchungechunge/ Ama-granule e-Polycarbonate/Izinto zokusetshenziswa zepulasitiki/Intengo yezinto zokusetshenziswa zepulasitiki ze-Tpu
mayelana ne-TPU
I-thermoplastic polyurethane elastomer (TPU) uhlobo lwe-elastomer olungafakwa ipulasitiki ngokushisa nokuncibilikiswa yi-solvent. Inezakhiwo ezinhle kakhulu eziphelele ezifana namandla aphezulu, ukuqina okuphezulu, ukumelana nokuguguleka kanye nokumelana namafutha. Isebenza kahle ekucubunguleni futhi isetshenziswa kabanzi ekuvikeleni kwezwe, kwezokwelapha, kokudla nakwezinye izimboni. I-Thermoplastic Polyurethane inezinhlobo ezimbili: uhlobo lwe-polyester nohlobo lwe-polyether, izinhlayiya ezimhlophe ezingahleliwe eziyindilinga noma ezikholamu, kanti ubuningi bungu-1.10~1.25g/cm3. Ubuningi obuhlobene bohlobo lwe-polyether buncane kunobohlobo lwe-polyester. Izinga lokushisa lokuguquka kwengilazi lohlobo lwe-polyether lingu-100.6~106.1℃, kanti izinga lokushisa lokuguquka kwengilazi lohlobo lwe-polyester lingu-108.9~122.8℃. Izinga lokushisa lobuthakathaka lohlobo lwe-polyether nohlobo lwe-polyester liphansi kune--62℃, kanti ukumelana nokushisa okuphansi kohlobo lwe-polyether kungcono kunohlobo lwe-polyester. Izici ezivelele zama-elastomer e-thermoplastic e-polyurethane ukumelana okuhle kakhulu nokuguguleka, ukumelana okuhle kakhulu ne-ozone, ubulukhuni obuphezulu, amandla aphezulu, ukuqina okuhle, ukumelana okuphansi kwezinga lokushisa, ukumelana okuhle kwamafutha, ukumelana kwamakhemikhali kanye nokumelana nemvelo. Ukuzinza kwe-hydrolytic kohlobo lwe-ester kuphakeme kakhulu kunohlobo lwe-polyester.

Amanani angenhla aboniswa njengamanani ajwayelekile futhi akufanele asetshenziswe njengemininingwane.
Iphakheji
25KG/isikhwama, 1000KG/iphalethi noma 1500KG/iphalethi, iphalethi yepulasitiki ecutshunguliwe
Ukuphatha Nokugcina Isitoreji
1. Gwema ukuphefumula umusi kanye nomhwamuko wokucubungula ukushisa
2. Imishini yokuphatha imishini ingabangela ukwakheka kothuli. Gwema ukuphefumula uthuli.
3. Sebenzisa amasu afanele okusekela phansi lapho uphatha lo mkhiqizo ukuze ugweme ukushaja kwe-electrostatic
4. Ama-pellet phansi angase ashelele futhi abangele ukuwa
Izincomo zokugcina: Ukuze ugcine ikhwalithi yomkhiqizo, gcina umkhiqizo endaweni epholile neyomile. Gcina esitsheni esivalwe kahle.
