I-Thermoplastic polyurethane (TPU) ayinayo kuphela iipropathi zerubha ze-polyurethane edibeneyo, njengamandla aphezulu, ukumelana nokunxiba okuphezulu, kodwa ineempawu ze-thermoplastic zezixhobo ze-polymer ezihambelanayo, ukwenzela ukuba ukusetyenziswa kwayo kunokwandiswa kwintsimi yeplastiki.Ngokukodwa kumashumi eminyaka akutshanje, i-TPU iye yaba yenye yezona zinto zikhawulezayo eziphuhlayo zepolymer.
I-TPU inoxinzelelo oluphezulu, uxinzelelo oluphezulu, ukuqina, kunye neempawu zokumelana nokwaluphala, nto leyo eyenza ukuba ibe yimathiriyeli eqolileyo kunye nokusingqongileyo.Inamandla amakhulu, ukuqina okuhle, ukumelana nokunxiba, ukumelana nokubanda, ukuxhathisa kweoli, ukuxhathisa kwamanzi, ukuguga, kunye nokumelana nemozulu, okungenakuqhathaniswa nezinye izinto zeplastiki.Kwangaxeshanye, inobumanzi obuphezulu kunye nokungena kwamanzi, ukumelana nomoya, ukumelana nokubanda, iipropathi ze-antibacterial, ukumelana nokungunda, kunye nemisebenzi emininzi egqwesileyo, njengokugcina ubushushu, ukuxhathisa kwe-UV, kunye nokukhululwa kwamandla.
I-TPU inoluhlu olubanzi lwamaqondo obushushu okusebenza.Uninzi lweemveliso zingasetyenziselwa ixesha elide kuluhlu lwe-40-80 ℃, kwaye ubushushu bexesha elifutshane lokusebenza bunokufikelela kwi-120 ℃.Amacandelo athambileyo kwisakhiwo secandelo le-TPU macromolecules anquma ukusebenza kwawo okuphantsi kobushushu.I-polyester yohlobo lwe-TPU inomgangatho ophantsi wobushushu obuphantsi kunye nokuguquguquka kunohlobo lwe-polyether ye-TPU.Ukusebenza kobushushu obuphantsi kwe-TPU kuchongwa ngubushushu bokuqala beglasi yokutshintsha kwecandelo elithambileyo kunye nobushushu obuthambileyo becandelo elithambileyo.Uluhlu lwenguqu yeglasi luxhomekeke kumxholo wecandelo elinzima kunye neqondo lokuhlukana kwesigaba phakathi kwamacandelo athambileyo kunye anzima.Njengoko umxholo wamacandelo anzima ukhula kwaye iqondo lokuhlukana kwesigaba liyancipha, uluhlu lokuguqulwa kweglasi lwamacandelo athambileyo lukwandiswa ngokufanelekileyo, okuya kubangela ukusebenza kakubi kobushushu obuphantsi.Ukuba i-polyether enokungahambi kakuhle kunye necandelo elinzima lisetyenziswa njengecandelo elithambileyo, ukuguquguquka okuphantsi kwe-TPU kunokuphuculwa.Xa ubunzima be-molecular yecandelo elithambileyo linyuka okanye i-TPU ivaliwe, iqondo lokungahambelani phakathi kwamacandelo athambileyo kunye anzima nawo aya kwanda.Kwiqondo lokushisa eliphezulu, ukusebenza kwayo kugcinwa ikakhulu ngamacandelo anzima, kwaye ukuphakama kobunzima bemveliso, kuphezulu ubushushu benkonzo yayo.Ukongeza, ukusebenza kobushushu obuphezulu akuhambelani kuphela nobungakanani be-chain extender, kodwa ikwaphenjelelwa luhlobo lwe-chain extender.Umzekelo, iqondo lobushushu bokusetyenziswa kwe-TPU efunyenwe ngokusebenzisa (i-hydroxyethoxy) benzene njenge-chain extender iphezulu kune-TPU efunyenwe ngokusebenzisa i-butanediol okanye i-hexanediol njenge-chain extender.Uhlobo lwe-disocyanate lukwachaphazela ukusebenza kobushushu obuphezulu be-TPU, kunye ne-diisocyanates eyahlukeneyo kunye nezandiso zamakhonkco njengoko amacandelo anzima abonisa iindawo ezahlukeneyo zokunyibilika.
Okwangoku, umda wesicelo sefilimu ye-TPU uya usiba banzi kwaye ubanzi, kwaye ngokuthe ngcembe uyakhula ukusuka kwizihlangu zemveli, amalaphu, iimpahla ukuya kwi-aerospace, emkhosini, kwizinto zombane kunye namanye amacandelo.Kwangaxeshanye, ifilimu ye-TPU yinto entsha yoshishino enokuguqulwa ngokuqhubekayo.Inokwandisa intsimi yesicelo ngokuguqulwa kwezinto eziluhlaza, ukulungiswa kwefomula yezinto eziphathekayo, ukulungiswa kwenkqubo yokuvelisa kunye nezinye iindlela, ngaloo ndlela inika ifilimu ye-TPU indawo eninzi yokuyisebenzisa.Kwixesha elizayo, umgangatho weteknoloji yezoshishino uya kuphuculwa, Ukusetyenziswa kwe-TPU kuya kuqhubela phambili.
Zeziphi izicelo zangoku ze-TPU kwinkampani yethu?
Njengoko iimoto zidlala indima ebalulekileyo ebomini bethu, imfuno yokhuseleko lwezithuthi phakathi kwabanini-moto nayo iyanda.Ifilimu yokukhusela ipeyinti ye-TPU iyisisombululo esifanelekileyo sokujongana nale mfuno.
Enye yeempawu zefilimu yokukhusela ipeyinti ye-TPU yindlela ebalaseleyo yokuxhathisa ukukrazula, enokuthi ixhathise ngokufanelekileyo impembelelo yezinto ezibukhali ezifana negrabile kunye nesanti endleleni, kunye nokukhusela umzimba kwimikrwelo kunye nezibonda.Akusekho mfuneko yokukhathazeka malunga nomonakalo onokwenzeka ngexesha lokuqhuba, kwaye unokugxila ngakumbi endleleni kunye namava okuqhuba xa uqhuba.
