Yenziwe ngantoni iTPU? -Ukuqonda ngokunzulu i-thermoplastic polyurethane elastomers
I-Thermoplastic Polyurethane Elastomer (TPU) yimathiriyeli yepolymer ene-elasticity ephezulu, ukuchasana nokukrala, i-oyile kunye negrisi, kunye neempawu zokuchasana nokuguga. Ngenxa yokusebenza kwayo okuphezulu, i-TPU isetyenziswa ngokubanzi kumashishini ahlukeneyo, ukusuka kwizinto zezicathulo, iimeko zokukhusela iimveliso ze-elektroniki kwiindawo zezixhobo zoshishino, i-TPU inoluhlu olubanzi lwezicelo.
Ubume obusisiseko kunye nokuhlelwa kwe-TPU
I-TPU yi-copolymer yebhloko yomgca, equka iindawo ezimbini: inxalenye enzima kunye nenxalenye ethambileyo. Icandelo elinzima lihlala liqulunqwe nge-disocyanate kunye ne-chain extender, ngelixa i-soft segment yenziwe nge-polyether okanye i-polyester diol. Ngokulungelelanisa umlinganiselo wamacandelo anzima kunye athambileyo, izinto ze-TPU ezinobunzima obuhlukeneyo kunye nokusebenza kunokufumaneka. Ngoko ke, i-TPU inokwahlulwa ibe ngamacandelo amathathu: i-polyester TPU, i-polyether TPU kunye ne-polycarbonate TPU.

I-Polyester TPU: Ngokumelana okugqwesileyo kwe-oyile kunye nokuchasana kweekhemikhali, idla ngokusetyenziswa ekuveliseni imibhobho yoshishino, izitywina kunye neendawo zeemoto.
I-TPU yohlobo lwe-Polyether: Ngenxa yokumelana kwayo ne-hydrolysis engcono kunye nokusebenza okuphantsi kobushushu, isoloko isetyenziswa kwintsimi yezinto zezicathulo, izixhobo zonyango kunye neengcingo kunye neentambo.
I-TPU yePolycarbonate: ukudibanisa izibonelelo ze-polyester kunye ne-polyether TPU, inokumelana nempembelelo engcono kunye nokungafihli, kwaye ifanelekile kwiimveliso ezicacileyo kunye neemfuno eziphezulu.

Iimpawu ze-TPU kunye neenzuzo zesicelo
I-TPU ibalasele kwezinye izinto ezininzi ezineempawu zayo ezizodwa. Ezi zakhiwo ziquka ukuxhathisa okuphezulu kwe-abrasion, amandla abalaseleyo oomatshini, u-elasticity elungileyo kunye ne-transparency.TPU ephezulu inokumelana ne-oyile, izinyibilikisi kunye nobushushu obuphantsi. Ezi zibonelelo zenza i-TPU ibe yimathiriyeli efanelekileyo kwiimveliso ezifuna zombini ukuguquguquka kunye namandla.

Ukuxhathisa i-abrasion kunye nokunwebeka: Ukuxhathisa okuphezulu kwe-TPU kunye nokunwebeka okulungileyo kuyenza ibe yimathiriyeli yokuzikhethela kwiimveliso ezinjengeebhola zezihlangu, amatayara kunye namabhanti okuhambisa.
Ukumelana nemichiza kunye ne-oyile: Kumashishini ekhemikhali kunye namashishini, i-TPU isetyenziswa ngokubanzi kwiindawo ezifana ne-hoses, i-seal kunye ne-gaskets ngenxa ye-oyile kunye nokuchasana kwe-solvent.
Ukucaca okuphezulu: I-TPU ecacileyo isetyenziswa ngokubanzi kwiimeko ezikhuselayo kwiimveliso zombane kunye nezixhobo zonyango ngenxa yeempawu zayo ezibalaseleyo.

Inkqubo yemveliso kunye nefuthe lokusingqongileyo kweTPU
Inkqubo yemveliso ye-TPU ikakhulu ibandakanya i-extrusion, isitofu sokubumba kunye neendlela zokuvuthela, ezimisela ifom kunye nokusebenza kwemveliso yokugqibela. Ngenkqubo ye-extrusion, i-TPU inokwenziwa kwiifilimu, iipleyiti kunye neetyhubhu; ngenkqubo yokubumba inaliti, i-TPU inokwenziwa kwiimilo ezintsonkothileyo zamalungu; ngenkqubo yokubumba ivuthela, inokwenziwa kwiimveliso ezahlukeneyo ezingenanto.
Ukusuka kwindawo yokujonga indalo, i-TPU yinto enokuphinda isetyenziswe kwi-thermoplastic, ngokungafaniyo ne-elastomers ye-thermoset yendabuko, i-TPU isenokuthi inyibilikiswe kwaye iphinde iphinde iphinde iqhutywe emva kokufudumeza. Olu phawu lunika i-TPU inzuzo ekunciphiseni inkunkuma kunye nokunciphisa ukukhutshwa kwekhabhoni. Ngexesha lemveliso kunye nokusetyenziswa, ingqwalasela kufuneka ihlawulwe kwimpembelelo yayo yokusingqongileyo enokubakho, efana ne-volatile organic compound (VOC) ekhutshwayo enokuthi iveliswe ngexesha lokucubungula.
Imbonakalo yemarike yeTPU kunye nentsingiselo yophuhliso
Ngemfuno ekhulayo yokusebenza okuphezulu, izixhobo ezihambelana nokusingqongileyo, imbonakalo yentengiso yeTPU ibanzi kakhulu. Ngokukodwa kwiinkalo zezihlangu, iimveliso ze-elektroniki, imboni yeemoto kunye nezixhobo zonyango, ukusetyenziswa kwe-TPU kuya kwandiswa ngakumbi. Kwixesha elizayo, ngophuhliso kunye nokusetyenziswa kwe-TPU esekwe kwi-bio kunye ne-TPU ewohlokayo, ukusebenza kokusingqongileyo kwe-TPU kulindeleke ukuba kuphuculwe ngakumbi.
Isishwankathelo, i-TPU yimathiriyeli ye-polymer ene-elasticity kunye namandla, kunye nokuxhathisa kwayo okugqwesileyo kwe-abrasion, ukumelana neekhemikhali kunye nokusetyenzwa kwayo kuyenza ingabinandawo kumashishini amaninzi. Ngokuqonda "into eyenziwe ngayo i-TPU", sinokuqonda ngcono amandla kunye nesikhokelo sale nto kuphuhliso lwexesha elizayo.
