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.

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.
