I-adhesive ye-TPU esekwe kwi-Solvent-based viscosity elungileyo
malunga ne-TPU
I-TPU (i-thermoplastic polyurethanes) ivala umsantsa wezinto ezisetyenziswayo phakathi kweerabha kunye neeplastiki. Uluhlu lweempawu zayo ezibonakalayo lwenza i-TPU isetyenziswe njengerabha eqinileyo kunye ne-thermoplastic yobunjineli ethambileyo. I-TPU ifikelele ekusetyenzisweni ngokubanzi kunye nokuthandwa kumawaka eemveliso, ngenxa yokuqina kwayo, ukuthamba kwayo kunye nombala wayo phakathi kwezinye izibonelelo. Ukongeza, kulula ukuyicubungula.
Njengezixhobo zobuchwepheshe obuphezulu nezinobuhlobo nokusingqongileyo, i-TPU ineempawu ezininzi ezintle ezifana nobubanzi bobunzima, amandla aphezulu oomatshini, ukumelana nokubanda okugqwesileyo, ukusebenza kakuhle kokucubungula, ukonakala okunobuhlobo nokusingqongileyo, ukumelana neoyile, ukumelana namanzi kunye nokumelana nokungunda.

Amaxabiso angasentla aboniswa njengexabiso eliqhelekileyo kwaye akufuneki asetyenziswe njengeenkcukacha.
Iphakheji
25KG/ibhegi, 1000KG/ipalethi okanye 1500KG/ipalethi, ipalethi yeplastiki ecutshungulweyo
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.
Amanqaku
1. Izixhobo zeTPU eziwohlokileyo azinakusetyenziselwa ukucubungula iimveliso.
2. Ngaphambi kokubumba, kuyimfuneko ukomisa ngokupheleleyo, ingakumbi ngexesha lokubumba i-extrusion, ukubumba i-blow, kunye nokubumba ifilimu, kunye neemfuno ezingqongqo zobungakanani bokufuma, ngakumbi ngamaxesha onyaka anomswakama kunye neendawo ezinomswakama ophezulu.
3. Ngexesha lokuvelisa, ulwakhiwo, umlinganiselo woxinzelelo, ubunzulu bomngxuma, kunye nomlinganiselo wobungakanani be-L/D yesikrufu kufuneka kuqwalaselwe ngokusekelwe kwiimpawu zezinto ezisetyenzisiweyo. Izikrufu zokubumba inaliti zisetyenziselwa ukubumba inaliti, kwaye izikrufu zokubumba intambo zisetyenziselwa ukubumba intambo.
4. Ngokusekelwe kukuguquguquka kwezinto, qwalasela isakhiwo sesikhunta, ubungakanani bokungena kweglue, ubungakanani be-nozzle, isakhiwo se-flow channel, kunye nendawo ye-exhaust port.
