Solvent-Isekelwe TPU ancamathelise viscosity elungileyo
malunga neTPU
I-TPU (i-thermoplastic polyurethanes) ivala umsantsa wezinto ezibonakalayo phakathi kweerabha kunye neeplastiki. Uluhlu lwayo lweempawu ezibonakalayo lwenza ukuba i-TPU isetyenziswe njengerabha eqinileyo kunye nobunjineli obuthambileyo be-thermoplastic.TPU izuze ukusetyenziswa okuxhaphakileyo kunye nokuthandwa kumawaka eemveliso, ngenxa yokuqina kwazo, ukuthamba kunye nombala phakathi kwezinye izibonelelo. Ukongeza, kulula ukusetyenzwa.
Njengobuchwephesha obuphezulu obuvelayo kunye nezixhobo ezihambelana nokusingqongileyo, i-TPU ineempawu ezininzi ezibalaseleyo njengoluhlu lobunzima obubanzi, amandla omatshini aphezulu, ukumelana nokubanda okubalaseleyo, ukusebenza kakuhle kokusetyenzwa, ukonakaliswa kokusingqongileyo, ukunganyangeki kwe-oyile, ukuxhathisa kwamanzi kunye nokumelana nokungunda.
Isicelo
Usetyenziso: I-Solvent Adhesives, i-Hot-melt Adhesive Films, i-Adhesive Footwear.

Iphakheji
I-25KG / ibhegi, i-1000KG / ipallet okanye i-1500KG / ipallet, ipalethi yeplastiki eyenziwe yalungiswa
Ukuphatha kunye noGcino
1. Kuphephe ukuphefumla umsi wokulungiswa kwe-thermal kunye nomphunga
2. Izixhobo zokuphatha oomatshini zinokubangela ukubunjwa kothuli. Kuphephe ukuphefumla uthuli.
3. Sebenzisa iindlela ezifanelekileyo zokumisa xa uphethe le mveliso ukuphepha iintlawulo ze-electrostatic
4. Iipellets emgangathweni zingatyibilika kwaye zibangele ukuwa
Iingcebiso zokugcina: Ukugcina umgangatho wemveliso, gcina imveliso kwindawo epholileyo, eyomileyo. Gcina kwisitya esivaliweyo.
Amanqaku
1. Izinto zeTPU eziwohlokileyo azinakusetyenziselwa ukucubungula iimveliso.
2. Ngaphambi kokubunjwa, kuyimfuneko ukomisa ngokupheleleyo, ngokukodwa ngexesha lokubunjwa kwe-extrusion, ukubunjwa kwe-blow, kunye nefilimu yokuvuthela ifilimu, kunye neemfuneko ezingqongqo zomxholo womswakama, ngokukodwa kwixesha elimanzi kunye neendawo zomswakama ophezulu.
3. Ngexesha lokuvelisa, isakhiwo, ukunyanzeliswa komlinganiselo, ubunzulu be-groove, kunye ne-aspect ratio L / D ye-screw kufuneka ithathelwe ingqalelo ngokusekelwe kwiimpawu zezinto eziphathekayo. Isikrufu sokubumba isitofu sisetyenziselwa ukubumba inaliti, kwaye izikrufu ze-extrusion zisetyenziselwa ukukhupha.
4. Ngokusekwe kubumanzi bezinto eziphathekayo, qwalasela isakhiwo sokubumba, ubungakanani be-glue inlet, ubungakanani be-nozzle, isakhiwo somjelo wokuhamba, kunye nendawo ye-exhaust port.
