Ukusetshenziswa kwe-polyurethane

I-Polyurethane ingasetshenziswa ekwenzeni amapulasitiki, irabha, imicu, amagwebu aqinile futhi aguquguqukayo, izinto zokunamathisela kanye nama-coatings, njll. Ingasetshenziswa emikhakheni ehlukahlukene yokuphila kwabantu futhi inezinhlobonhlobo zezicelo.

1. Igwebu le-polyurethane:

Ihlukaniswe yaba igwebu le-polyurethane eliqinile, igwebu le-polyurethane eliqinile kancane kanye negwebu le-polyurethane eliguqukayo.Igwebu le-polyurethane eliqinile lisetshenziselwa ikakhulukazi ukwakha izinto zokufakelwa ezishisayo, izinto zokufakelwa ezishisayo (izinsiza zamapayipi, njll., ukufakwa kwe-thermal kanye nokusetshenziswa kwansuku zonke) (imibhede, osofa, njll., omatilasi, iziqandisi, ama-air conditioner, njll., izingqimba zokufakelwa, kanye ama-surfboard, njll. izinto ezibalulekile, kanye Nezokuthutha (izimoto, izindiza, izimoto zikaloliwe, amakhushini, osilingi nezinye izinto).

2. I-polyurethane elastomer:

I-polyurethane elastomer inezinzuzo zamandla amahle okudonsa, amandla okudabula, ukumelana nomthelela, ukumelana nokuhuzuka, ukumelana nesimo sezulu, ukumelana ne-hydrolysis, ukumelana nowoyela nokunye.Isetshenziselwa ikakhulukazi izinto zokumboza (ezifana nokuvikela amapayipi, amawasha, amathayi, amarola, amagiya, amapayipi, njll.), ama-insulators, amasoli ezicathulo, namathayi aqinile.

3. I-polyurethane engangeni manzi:

I-polyurethane engangeni manzi kulula kakhulu ukuyisebenzisa.Ingaxutshwa esizeni futhi yelashwe ngokushisa okuvamile kanye nomswakama ngemva kokumboza, bese kuthi isendlalelo esingenamanzi esingenawo ama-seams, ukunwebeka kwenjoloba nokusebenza kahle kungatholakala.Futhi kulula ukulungisa ngemva kokulimala.Isetshenziswa ngokujwayelekile njengezinto zokugandaya, ithrekhi kanye nezinto zethrekhi yasensimini, amathrekhi omjaho, izinto zasensimini yepaki, amafreyimu wefasitela wokushisa okushisa, njll.

4. I-polyurethane enamathela:

I-polyurethane enamathela inokunamathela okuqinile, futhi ifilimu yokumboza inokumelana okuhle kakhulu nokugqoka, ukumelana kwamanzi nokumelana namakhemikhali.Ikakhulukazi esetshenziselwa ukumboza ifenisha, okokuhlanganisa izinto zokwakha kanye noyinki wokunyathelisa wezimboni.

5. Ukunamathela kwe-polyurethane:

Ukusebenza komkhiqizo ophulukisiwe kungalungiswa ngokulungisa isilinganiso se-isocyanate ne-polyol, ukuze sikwazi ukufeza ukunamathela okuphezulu ku-substrate, ukumelana kwamanzi okuhle kakhulu, ukumelana nowoyela kanye nokumelana namakhemikhali.Ama-adhesive e-polyurethane asetshenziswa kakhulu ekupakisheni, ekwakhiweni, ezinkuni, ezimoto, ekuthungeni izicathulo nakwezinye izimboni.

6. Izinto ze-Biomedical:

I-Polyurethane ine-biocompatibility enhle kakhulu, ngakho kancane kancane isetshenziswa kabanzi njengezinto ze-biomedical.Ingasetshenziswa ekwenzeni ama-pacemakers enhliziyo yokwenziwa, imithambo yegazi yokwenziwa, amathambo okwenziwa, umminzo wokwenziwa, izinso zokwenziwa, ulwelwesi lokwenziwa lwe-dialysis, njll.
