TPU Ityala leFowuni: I-Advanteji kunye ne-Didvantage

Abasebenzisi abaninzi baya kuxhobisa iifowuni zabo nge "idyasi" (ityala lefowuni), elinokunciphisa kakhulu umonakalo xa behla ngengozi. Kukho iintlobo ezininzi zezixhobo zezi meko zefowuni, ezifana ne-silicone, iplastiki, i-resin, TPU, Njl

Yintoni i TPU Ityala lefowuni lenziwe?

I-Thermoplastic polyurethane elastomer (TPU), eyaziwa ngokuba yirabha ye-polyurethane, luhlobo lwe-elastic polymer material equlethe inani elikhulu lamaqela e-amino acid ester (-NHCOO-) kwikhonkco le-molecular. Yimpahla yeplastiki enokuthi ithobe ngokuphindaphindiweyo okanye iguqule kwiqondo lokushisa elithile, ngelixa likwazi ukugcina imilo yalo kwaye lidlale indima exhasayo kunye nokukhusela kwiqondo lokushisa. Isetyenziswe ngokubanzi kwizinto ezinxitywayo zezicathulo, i-adhesives, imibhobho, iifilimu, isikhumba sokwenziwa, iingcingo kunye neentambo, iideshibhodi, iimeko zefowuni, i-bandages zonyango, njl.

Ngophuculo lwe TPU ukusebenza kwezinto, izixhobo zemidlalo kunye nezixhobo zezihlangu ziya zithandeka ngakumbi TPU iimveliso, ingakumbi izixhobo UV-resistant kunye elubala. Ngoko ke, TPU izinto eziphathekayo zinamandla amakhulu okuphuhlisa kwintsimi yempahla yezemidlalo kunye nezixhobo zezicathulo zemidlalo.

Is TPU ifowuni inzima okanye ithambile?

TPU Ityala lefowuni lithambile, kodwa liqine kancinci kune-silicone, kwaye linokuqina okunamandla.

TPU yibhloko ye-copolymer, kwaye umlinganiselo wamacandelo anzima kwaye athambileyo amisela ukusebenza kwe TPU. Icandelo elinzima linempembelelo ekhethekileyo kwi-modulus, ubunzima, kunye namandla okukrazula, ngelixa icandelo elithambileyo lichaphazela kakhulu ukuqina kunye nokusebenza okuphantsi kobushushu bemveliso. TPU inokuguquguquka okugqwesileyo kunye nokomelela, kwaye inokususela kwi-soft kakhulu ukuya kolukhuni kakhulu, ukusuka ekuguquguqukeni okulungileyo ukuya ekuqineni okuphezulu, okanye kwiintlobo ze-hydrophilic ezinokufunxa amanzi kwiintlobo ze-hydrophobic ezigxotha amanzi. Igcina i-elasticity ephezulu ngaphakathi koluhlu olubanzi lobunzima (i-Shore A10-D75), kwaye inomthwalo ophezulu wokuthwala umthwalo kunezinye ii-elastomers kubulukhuni obufanayo.

Ngaba TPU Ityala lefowuni lijika libe tyheli?

Ewe, ukuba uthenga ifowuni ecacileyo okanye enombala okhanyayo njengomhlophe, iya kuba tyheli kwiinyanga ezintathu ukuya kwezine. Nangona kunjalo, ukuba ijika ibe tyheli kwaye ingabi yinkungu okanye incangathi, oko kuthetha ukuba umgangatho we TPU ifowuni oyithengileyo iselungile. Ukutyheli kwe TPU icala lefowuni linxulumene nokukhethwa kwezinto eziluhlaza. Ukusebenza okuchasene nokuguga kweehydrocarbons ezihluthisiweyo kubhetele kuneehydrocarbons ezinevumba elimnandi. Ukongeza, ukongeza i-antioxidants kunye ne-UV-resistant additives kunokuphucula ingxaki ye-yellowing.

Izinto eziluncedo nezingalunganga ze TPU ityala lefoni

Olona loncedo lukhulu TPU Isixhobo kukuguquguquka kwayo okuhle, okunokonakala ngokulula. Ngoko ke, iimeko zefowuni ezenziwe ngolu hlobo zinomsebenzi omhle wokuthobisa, zinokuthintela ngokufanelekileyo ukuhla, kwaye kulula ukuyifaka nokususa. Ukwengeza, TPU izinto eziphathekayo zingasebenzisa iteknoloji ye-micro-matte ukukhusela ngokufanelekileyo iminwe yeminwe kunye nokuqinisekisa ukucoceka kwefowuni. TPU I-elastomer yinto ephakathi kwerabha kunye neplastiki. Inemisebenzi yokunganyangeki kweoli, ukunganyangeki kwamanzi, kunye nokumelana nokungunda. TPU iimveliso zinomthamo obalaseleyo wokuthwala umthwalo, ukuxhathisa impembelelo, kunye nokusebenza kokufunxa ukothuka. TPU yeyodidi lweplastiki, kwaye imveliso yenziwe ngenkqubo yokubumba inaliti. Emva kokufudumeza kunye nokunyibilika kweenkozo zeplastiki zerayisi, zifakwe kwi-mold yeplastiki kunye ne-barrel ukwenza imveliso.

Izinto eziluncedo: ukumelana nokunxiba okuphezulu, ukomelela okuphezulu, ukumelana nokubanda okugqwesileyo, ukumelana ne-oyile, ukunganyangeki kwamanzi, ukumelana nokungunda, kunye nokuguquguquka okuhle.

Ukungalungi: kulula ukukhubaza kwaye ujike ube tyheli.
