Imfihlakalo yefilimu ye-TPU: ukwakheka, inkqubo kunye nohlalutyo lwesicelo
Ifilimu ye-TPU, njengesixhobo se-polymer esisebenza kakuhle, idlala indima ebalulekileyo kwiindawo ezininzi ngenxa yeempawu zayo zomzimba nezekhemikhali ezikhethekileyo. Eli nqaku liza kujonga kwizinto zokwakheka, iinkqubo zemveliso, iimpawu, kunye nokusetyenziswa kwefilimu ye-TPU, likusa kuhambo oluya kwi-app...Funda ngokugqithisileyo -
Abaphandi baphuhlise uhlobo olutsha lwezinto zokufunxa uloyiko ze-thermoplastic polyurethane elastomer (TPU)
Abaphandi abavela kwiYunivesithi yaseColorado eBoulder naseSandia National Laboratory baphuhlise izinto eziguqula ukukhwankqiswa, nto leyo ephucukileyo enokutshintsha ukhuseleko lweemveliso ukusuka kwizixhobo zemidlalo ukuya kwezothutho. Le shoc intsha...Funda ngokugqithisileyo -
Imiyalelo ephambili yophuhliso lwexesha elizayo lwe-TPU
I-TPU yi-polyurethane thermoplastic elastomer, eyi-multiphase block copolymer eyenziwe ngama-diisocyanates, ii-polyols, kunye nee-chain extenders. Njenge-elastomer esebenza kakhulu, i-TPU inoluhlu olubanzi lwemiyalelo yemveliso esezantsi kwaye isetyenziswa kakhulu kwizinto eziyimfuneko zemihla ngemihla, izixhobo zemidlalo, iithoyi,...Funda ngokugqithisileyo -
Ibhola yomnyazi entsha yeTPU engenagesi yepolymer ikhokela umkhwa omtsha kwezemidlalo
Kwintsimi enkulu yemidlalo yebhola, ibasketball ibisoloko idlala indima ebalulekileyo, kwaye ukuvela kwebasketball yeTPU engenagesi yepolymer kuzise impumelelo entsha kunye notshintsho kwibasketball. Kwangaxeshanye, kukwabangele umkhwa omtsha kwimarike yeempahla zemidlalo, okwenza i-polymer gas...Funda ngokugqithisileyo -
Umahluko phakathi kohlobo lwe-TPU polyether kunye nohlobo lwe-polyester
Umahluko phakathi kohlobo lwe-TPU polyether kunye nohlobo lwe-polyester I-TPU inokwahlulwa ibe ziintlobo ezimbini: uhlobo lwe-polyether kunye nohlobo lwe-polyester. Ngokweemfuno ezahlukeneyo zezicelo zemveliso, iintlobo ezahlukeneyo ze-TPU kufuneka zikhethwe. Umzekelo, ukuba iimfuno ze-hydrolysis ziyamelana...Funda ngokugqithisileyo -
Iingenelo kunye nokungalungi kweekheyisi zefowuni zeTPU
I-TPU， Igama elipheleleyo yi-thermoplastic polyurethane elastomer, eyi-polymer material enobuthambileyo obuhle kunye nokumelana nokuguguleka. Ubushushu bayo bokutshintsha kweglasi buphantsi kunobushushu begumbi, kwaye ubude bayo xa iqhekeka bungaphezulu kwama-50%. Ke ngoko, inokubuyisela imo yayo yokuqala ngaphandle...Funda ngokugqithisileyo
