I-Thermoplastic Polyurethane (TPU) Resin yeeCases zeFowuni eziphathwayo Iigranules zeTPU ezicacileyo eziphezulu Umenzi wePowder yeTPU
Malunga ne-TPU
I-TPU, isishunqulelo seThermoplastic Polyurethane, yi-thermoplastic elastomer emangalisayo eneempawu ezininzi ezibalaseleyo kunye noluhlu olubanzi lwezicelo.
I-TPU yi-block copolymer eyenziwe yi-reaction ye-diisocyanates kunye ne-polyols. Iqulathe amacandelo ahlukeneyo aqinileyo nathambileyo. Amacandelo aqinileyo anika ukuqina nokusebenza ngokomzimba, ngelixa amacandelo athambileyo enika ukuguquguquka kunye neempawu ze-elastomeric.
Iipropati
• Iipropati zoomatshini5: I-TPU inamandla aphezulu, inamandla okutsalwa amalunga ne-30 - 65 MPa, kwaye inokunyamezela ukuguguleka okukhulu, inobude xa iqhekeka ukuya kuthi ga kwi-1000%. Ikwanayo nokumelana nokukrala okugqwesileyo, inokumelana nokuguguleka okuphindwe kahlanu kunerabha yendalo, kwaye inokumelana nokukrazuka okuphezulu kunye nokumelana okugqwesileyo, okwenza ukuba ilungele ukusetyenziswa okufuna amandla aphezulu oomatshini.
• Ukumelana neekhemikhali5: I-TPU ayixhathisi kakhulu kwiioyile, iigrisi, kunye nezinyibilikisi ezininzi. Ibonisa uzinzo oluhle kwiioyile zepetroli nakwiioyile zoomatshini. Ukongeza, inokumelana okuhle neekhemikhali eziqhelekileyo, nto leyo eyandisa ubomi benkonzo yeemveliso kwiindawo zokunxibelelana kweekhemikhali.
• Iipropati zoBushushu: I-TPU inokusebenza ngokufanelekileyo kumanqanaba obushushu ukusuka kwi - 40 °C ukuya kwi-120 °C. Igcina ukuthamba okuhle kunye neempawu zoomatshini kubushushu obuphantsi kwaye ayiguquguquki okanye inyibilike lula kubushushu obuphezulu.
• Ezinye iiPropati4: I-TPU inokwenziwa ukuze kufezekiswe amanqanaba ahlukeneyo okucaca. Ezinye izinto ze-TPU zibonakala kakhulu, kwaye kwangaxeshanye, zigcina ukumelana nokukrweleka okuhle. Ezinye iintlobo ze-TPU nazo zinokuphefumla kakuhle, kunye nesantya sokudluliselwa komphunga esinokulungiswa ngokweemfuno. Ukongeza, i-TPU ihambelana kakuhle kakhulu ne-biochemical, kuba ayinabungozi, ayibangeli i-allergies, kwaye ayicaphukisi, nto leyo eyenza ukuba ifaneleke ukusetyenziswa kwezonyango.

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.
