I-TPU ingcina esekwe kwi-solvent viscosity enhle
mayelana ne-TPU
I-TPU (i-thermoplastic polyurethanes) ihlanganisa igebe lezinto ezibonakalayo phakathi kwerabha nepulasitiki. Ububanzi bezakhiwo zayo ezibonakalayo buvumela i-TPU ukuthi isetshenziswe njengerabha eqinile kanye ne-thermoplastic yobunjiniyela obuthambile. I-TPU ifinyelele ukusetshenziswa kabanzi kanye nokuthandwa ezinkulungwaneni zemikhiqizo, ngenxa yokuqina kwayo, ubumnene kanye nombala phakathi kwezinye izinzuzo. Ngaphezu kwalokho, kulula ukuyicubungula.
Njengezinto zobuchwepheshe obuphezulu nezinobungani nemvelo, i-TPU inezakhiwo eziningi ezinhle kakhulu njengobubanzi bobulukhuni, amandla aphezulu okusebenza, ukumelana nokubanda okuvelele, ukusebenza kahle kokucubungula, ukuwohloka okunobungani nemvelo, ukumelana namafutha, ukumelana namanzi kanye nokumelana nesikhunta.

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.
Amanothi
1. Izinto ze-TPU eziwohlokile azikwazi ukusetshenziselwa ukucubungula imikhiqizo.
2. Ngaphambi kokubumba, kuyadingeka ukuthi komise ngokuphelele, ikakhulukazi ngesikhathi sokubumba okuphumayo, ukubumba okuphuphumayo, kanye nokubumba okuphuphumayo kwefilimu, ngezidingo eziqinile zokuqukethwe komswakama, ikakhulukazi ezinkathini zomswakama nezindawo ezinomswakama ophezulu.
3. Ngesikhathi sokukhiqiza, isakhiwo, isilinganiso sokucindezelwa, ukujula komsele, kanye nesilinganiso se-aspect ratio L/D sesikulufu kufanele kucatshangelwe ngokusekelwe ezicini zezinto ezibonakalayo. Izikulufu zokubumba umjovo zisetshenziselwa ukubumba umjovo, kanti izikulufu zokubumba umjovo zisetshenziselwa ukubumba umjovo.
4. Ngokusekelwe ekugelezeni kwezinto, cabanga ngesakhiwo sesikhunta, usayizi wokungena kweglue, usayizi we-nozzle, isakhiwo sesiteshi sokugeleza, kanye nendawo yembobo yokukhipha umoya.
