Kwishishini lezinto zokwakha zanamhlanje, ngakumbi nangakumbi i-polyurethane inokubonwa kwimarike.I-Polyurethane yimathiriyeli eguquguqukayo kakhulu, kodwa abantu abaninzi abaqondi ukuba yintoni i-polyurethane okanye yenza ntoni.Ukuphendula le meko, umhleli uye waqulunqa olu lwazi lulandelayo ukukunika isayensi edumileyo.“

Yintoni iPolyurethane?

Igama elipheleleyo le-polyurethane yi-polyurethane, eligama eliqhelekileyo kwiikhompawundi ze-macromolecular eziqukethe amaqela aphindaphindayo e-urethane kwikhonkco eliphambili.I-Polyurethane liqela elincinci le-urethane kwilizwe lam, kwaye inokuqulatha i-ether ester urea biuret urea iqela lokuqala lentshayelelo ye-polyurethane.Yenziwe nge-polyaddition ye-organic diisocyanate okanye i-polyisocyanate kunye ne-dihydroxyl okanye i-polyhydroxyl ikhompawundi.Izinto zePolyurethane zineendlela ezininzi zokusetyenziswa, zinokuthatha indawo yerabha, iplastiki, inayiloni, njl., esetyenziswa kwizikhululo zeenqwelomoya, iihotele, izixhobo zokwakha, iifektri zemoto, imigodi yamalahle, iifektri zesamente, amagumbi aphezulu, iivillas, indawo yokuhlala, ilitye elinemibala. ubugcisa, ipaki njl.

Indima ye-polyurethane:

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. I-polyurethane foam: ihlukaniswe ibe yi-polyurethane foam eqinile, i-semi-rigid polyurethane foam kunye ne-flexible polyurethane foam.I-polyurethane foam eqinile isetyenziselwa kakhulu ukwakha izinto zokugquma kwe-thermal, izixhobo zokugquma kwe-thermal (ukugquma kwe-thermal yezibonelelo zemibhobho, njl. njl.), iimfuno zemihla ngemihla (iibhedi, iisofa, njl. , njl. njl. izinto ezingundoqo. ), kunye neendlela zothutho (izinto ezinjengamakhushini kunye neesilingi zeemoto, iinqwelomoya, kunye nezithuthi zikaloliwe).

2. I-polyurethane elastomer: I-polyurethane elastomer ineengenelo zamandla amahle okuqina, amandla okukrazula, ukuxhathisa impembelelo, ukuxhathisa kwe-abrasion, ukumelana nemozulu, ukuxhathisa kwe-hydrolysis, ukuxhathisa kweoli njalo njalo.Isetyenziswa kakhulu kwizinto zokugquma (ezifana nokukhuselwa kwemibhobho, iiwasha, amathayi, iirola, iigiya, imibhobho, njl.njl.), i-insulators, izihlangu zezihlangu, kunye namavili aqinileyo.

3. Izinto ezingenamanzi ze-polyurethane: Izinto ezingenamanzi ze-polyurethane zilungele kakhulu ukusebenzisa.Iyakwazi ukuxutywa kwaye ifakwe kwisayithi kwaye iphiliswe ngobushushu obuqhelekileyo kunye nomswakama, kunye noluhlu olungenamanzi olungenayo 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. I-polyurethane yokugqoka: I-polyurethane i-coating ine-adhesion eqinile, 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 adhesive: Ukusebenza kwemveliso ephilisiweyo kunokulungiswa ngokulungelelanisa umlinganiselo we-isocyanate kunye ne-polyol, ukwenzela ukuba ikwazi ukufezekisa ukunamathela okuphezulu kwi-substrate, ukuchasana kwamanzi okugqwesileyo, ukunyanzeliswa kweoli kunye nokuchasana kweekhemikhali.Izinto zokuncamathelisa zePolyurethane zisetyenziswa ikakhulu ekupakishweni, ukwakhiwa, iinkuni, iimoto, ukwenza izihlangu kunye namanye amashishini.

6. Izinto ze-Biomedical: 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.

Oku ngasentla lulunye ulwazi olufanelekileyo malunga nokuba yintoni impahla ye-polyurethane kunye nendima ye-polyurethane equlunqwe ngumhleli kuwe.I-Polyurethane ngokuthe ngcembe ifumana ukuqina okuqinileyo kwimakethi yezixhobo zokwakha ngenxa yokuxhathisa kwayo kunye nezinye iimpawu.Abasebenzisi be-intanethi banokuthenga ngokweemfuno zabo zokuphucula ikhaya.
