I-solvent-based tPu anamathela kahle
Mayelana ne-TPU
I-TPU (thermoplastic polyurethanes) ivala igebe lezinto ezibonakalayo phakathi kwama-rubber namapulasitiki. Uhla lwayo lwezinto ezibonakalayo lwenza ukuthi i-TPU ikwazi ukusetshenziswa njengenjoloba kanzima kanye ne- thermoplastic ethambile ye-Thermoplastic.tra ithole ukusetshenziswa okubanzi kanye nokuthandwa ngezinkulungwane zemikhiqizo, ngenxa yokuqina kwawo, ukuthamba kanye nokuqina kwawo phakathi kwezinye izinzuzo. Ngaphezu kwalokho, kulula ukucubungula.
Njengezinto ezivelayo zobuchwepheshe obuphakeme nezemvelo, i-TPU inezinto eziningi ezinhle kakhulu ezinjengebanga lobulukhuni obukhulu, amandla aphezulu okukhulisa, ukumelana okuhle, ukuwohloka kwemvelo, ukumelana kwamanzi, ukumelana kwamanzi kanye nokumelana kwamanzi.
Isicelo
Izicelo: Ama-solvent anamathela, amafilimu anamatheyisi ansundu, anamathela ezinyaweni.

Amanani angenhla aboniswa njengamanani ajwayelekile futhi akufanele asetshenziswe njengezichazayo.
Isishuqulu
I-25kg / isikhwama, i-1000kg / pallet noma i-1500kg / pallet, icutshungulwe ipallet yepulasitiki
Ukuphatha nokugcina
1
2. Imishini yokusingathwa kwemishini ingadala ukwakheka kothuli. Gwema ukuphefumula uthuli.
3. Sebenzisa amasu afanelekile lapho uphatha lo mkhiqizo ukugwema izindleko zikagesi
4. Ama-pellets phansi angahle ashelele futhi ambangele ukuwa
Izincomo Zokugcina: Ukugcina ikhwalithi yomkhiqizo, umkhiqizo wesitolo endaweni epholile, eyomile. Gcina esitsheni esivalwe ngokuqinile.
Amanothi
1. Ukuwohloka kwezinto ze-TPU azikwazi ukusetshenziselwa ukucubungula imikhiqizo.
2. Ngaphambi kokubumba, kuyadingeka yome ngokugcwele, ikakhulukazi ngesikhathi sokubumba kokukhishwa, ukushaya kwefilimu, kanye nokuvungulwa kwefilimu, ngezidingo eziqinile zokuqukethwe okunomswakama, ikakhulukazi ezindaweni ezinomswakama ezinomswakama.
I-3. Ngesikhathi sokukhiqiza, ukwakheka, isilinganiso sokucindezela, ukujula kwe-groove, kanye nesilinganiso se-aspect l / d yesikulufo kufanele kubhekwe ngokususelwa kuzimpawu zezinto ezibonakalayo. Izikulufu zokubumba zokujova zisetshenziselwa ukubumba kokujoyina, kanye nezikulufo ezingezelwe ukukhishwa zisetshenziselwa ukukhishwa.
4. Ngokusekelwe olwazini lwalokho okuqukethwe, cabanga ngesakhiwo sokubumba, usayizi we-glue inlet, usayizi we-nozzle, isakhiwo sesiteshi se-flow, kanye nesikhundla sechweba eliphumayo.
