Ukusetyenziswa kwePolyurethane

I-polyurethane ingasetyenziselwa ukwenziwa kweeplastiki, irabha, iintsinga, amagwebu aqinileyo kwaye aguquguqukayo, izinto zokuncamathelisa kunye neengubo, njl njl. Inokusetyenziswa kwiinkalo ezahlukeneyo zobomi babantu kwaye inoluhlu olubanzi lwezicelo.

1. Ugwebu lwepolyurethane:

Yahlulahlulwe yaba yi-polyurethane foam eqinileyo, i-semi-rigid polyurethane foam kunye ne-polyurethane foam eguquguqukayo.I-polyurethane foam eqinile isetyenziselwa ukwakha izinto zokugquma kwe-thermal, izixhobo zokugquma i-thermal (izixhobo zemibhobho, njl., ukugquma kwe-thermal kunye nokusetyenziswa kwemihla ngemihla) (iibhedi, iisofa, njl. iibhodi zokusefa, njl. njl. izixhobo ezingundoqo, kunye nezoThutho (iimoto, iinqwelo-moya, izithuthi zikaloliwe, iicushion, iisilingi kunye nezinye izinto).

2. Polyurethane elastomer:

I-Polyurethane elastomer ineengenelo zamandla okuqina okuhle, ukomelela kokukrazula, ukuxhathisa impembelelo, ukunganyangeki kwe-abrasion, ukumelana nemozulu, ukuxhathisa kwe-hydrolysis, ukuxhathisa kweoyile njalo njalo.Ikakhulu isetyenziselwa izinto zokugquma (ezifana nokukhuselwa kwemibhobho, iiwasha, amathayi, iirola, iigiya, imibhobho, njl.njl.), i-insulators, izihlangu zezihlangu, kunye namatayara aqinileyo.

3. Izinto zepolyurethane ezingenamanzi:

I-polyurethane engangeni manzi ilula kakhulu ukuyisebenzisa.Inokuxutywa kwisayithi kwaye iphiliswe ngobushushu obuqhelekileyo kunye nomswakama emva kokugquma, kwaye emva koko umaleko ongenamanzi ongenayo i-seams, i-rubber elasticity kunye nokusebenza kakuhle kunokufumaneka.Kwaye kulula ukuyilungisa emva komonakalo.Ngokuqhelekileyo zisetyenziswa njengezinto zokupakisha, umkhondo kunye nezixhobo zomkhondo webala, imidyarho, imathiriyeli yomhlaba wepaki, iifreyimu zefestile ze-thermal insulation, njl.

4. Ukwaleka ngepolyurethane:

I-Polyurethane yokugqoka inokubambelela okuqinileyo, kwaye ifilimu yokugqoka inokumelana nokugqwesa okugqwesileyo, ukuxhathisa kwamanzi kunye nokuchasana kweekhemikhali.Ikakhulu isetyenziselwa iingubo zefenitshala, izixhobo zokwakha kunye neenki zokushicilela kwimizi-mveliso.

5. I-polyurethane encamathelayo:

Ukusebenza kwemveliso ephilisiweyo kunokulungiswa ngokulungelelanisa umlinganiselo we-isocyanate kunye ne-polyol, ukwenzela ukuba ikwazi ukufezekisa ukunamathela okuphezulu kwi-substrate, ukuchasana kwamanzi okugqwesileyo, ukuchasana kweoli kunye nokuchasana kweekhemikhali.Izinto zokuncamathelisa zePolyurethane zisetyenziswa ikakhulu ekupakishweni, ukwakhiwa, iinkuni, iimoto, ukwenza izihlangu kunye namanye amashishini.

6. Iimathiriyeli zeBiomedical:

I-Polyurethane ine-biocompatibility egqwesileyo, ngoko ke ngokuthe ngcembe isetyenziswa ngokubanzi njengezinto ze-biomedical.Ingasetyenziselwa ukwenziwa kwee-pacemakers zentliziyo, imithambo yegazi eyenziweyo, amathambo enziweyo, i-esophagus eyenziweyo, izintso ezenziweyo, i-dialysis membranes, njl.
