I-thermoplastic polyurethane (TPU) ayinazo nje kuphela iimpawu zerabha ze-cross-linked polyurethane, ezinje ngamandla aphezulu, ukumelana nokuguguleka okuphezulu, kodwa ikwanazo neempawu ze-thermoplastic zezinto ze-linear polymer, ukuze ukusetyenziswa kwayo kunandiswe kwintsimi yeplastiki. Ingakumbi kwiminyaka yakutshanje, i-TPU ibe yenye yezinto ze-polymer eziphuhla ngokukhawuleza.
I-TPU ineempawu ezintle kakhulu zokuxinana, ukuxinana okuphezulu, ukuqina, kunye nokumelana nokuguga, nto leyo eyenza ukuba ibe yinto evuthiweyo nenobuhlobo nokusingqongileyo. Inamandla aphezulu, ukuqina okuhle, ukumelana nokuguguleka, ukumelana nokubanda, ukumelana neoyile, ukumelana namanzi, ukumelana nokuguga, kunye nokumelana nemozulu, izinto ezingenakuthelekiswa nezinye izinto zeplastiki. Kwangaxeshanye, ine-permeability ephezulu yokungangeni manzi kunye nokufuma, ukumelana nomoya, ukumelana nokubanda, iipropati zokulwa neentsholongwane, ukumelana nokungunda, kunye nemisebenzi emininzi emihle, njengokugcinwa kobushushu, ukumelana ne-UV, kunye nokukhululwa kwamandla.
I-TPU inoluhlu olubanzi lwamaqondo obushushu okusebenza. Uninzi lweemveliso zingasetyenziswa ixesha elide kuluhlu lwe--40-80 ℃, kwaye ubushushu bokusebenza bexesha elifutshane bunokufikelela kwi-120 ℃. Amacandelo athambileyo kwisakhiwo secandelo le-TPU macromolecules amisela ukusebenza kwawo kubushushu obuphantsi. Uhlobo lwe-polyester TPU lunokusebenza okuphantsi kobushushu obuphantsi kunye nokuguquguquka kunohlobo lwe-polyether TPU. Ukusebenza kobushushu obuphantsi kwe-TPU kugqitywa bubushushu bokuqala bokutshintsha kweglasi yecandelo elithambileyo kunye nobushushu obuthambileyo becandelo elithambileyo. Uluhlu lotshintsho lweglasi luxhomekeke kumxholo wecandelo eliqinileyo kunye nenqanaba lokwahlukana kwesigaba phakathi kwamacandelo athambileyo naqinileyo. Njengoko umxholo wamacandelo aqinileyo usanda kwaye inqanaba lokwahlukana kwesigaba liyancipha, uluhlu lotshintsho lweglasi lwamacandelo athambileyo nalo luyanda ngokufanelekileyo, nto leyo eya kukhokelela ekusebenzeni kakubi kobushushu obuphantsi. Ukuba i-polyether enokuhambelana okuphantsi necandelo eliqinileyo isetyenziswa njengecandelo elithambileyo, ukuguquguquka kobushushu obuphantsi kwe-TPU kunokuphuculwa. Xa ubunzima beemolekyuli zecandelo elithambileyo buyanda okanye i-TPU itshixiwe, inqanaba lokungahambelani phakathi kwamacandelo athambileyo naqinileyo nalo liya kwanda. Kumaqondo obushushu aphezulu, ukusebenza kwayo kugcinwa ikakhulu ziinxalenye zetyathanga eliqinileyo, kwaye okukhona ubunzima bemveliso buphezulu, kokukhona ubushushu bayo benkonzo buphezulu. Ukongeza, ukusebenza kobushushu obuphezulu akuhambelani nje kuphela nobungakanani betyathanga lokwandisa, kodwa kukwaphenjelelwa naluhlobo lwetyathanga lokwandisa. Umzekelo, ubushushu bokusetyenziswa kweTPU obufunyenwe ngokusebenzisa (hydroxyethoxy) benzene njengetyathanga lokwandisa buphezulu kunobo beTPU obufunyenwe ngokusebenzisa i-butanediol okanye i-hexanediol njengetyathanga lokwandisa. Uhlobo lwe-diisocyanate lukwachaphazela ukusebenza kobushushu obuphezulu be-TPU, kwaye ii-diisocyanates ezahlukeneyo kunye neetyathanga zokwandisa njengoko iinxalenye ezinzima zibonisa amanqaku ahlukeneyo okunyibilika.
Okwangoku, ububanzi bokusetyenziswa kwefilimu ye-TPU buya busanda, kwaye iyanda kancinci kancinci ukusuka kwizihlangu zemveli, amalaphu, iimpahla ukuya kwi-aerospace, emkhosini, kwi-elektroniki nakwezinye iindawo. Kwangaxeshanye, ifilimu ye-TPU sisixhobo esitsha semizi-mveliso esinokuguqulwa rhoqo. Ingandisa intsimi yayo yokusetyenziswa ngokuguqulwa kwezinto eziluhlaza, ukulungiswa kwefomyula yezinto, ukwenziwa ngcono kwenkqubo yemveliso kunye nezinye iindlela, ngaloo ndlela inika ifilimu ye-TPU indawo engakumbi yokusebenzisa. Kwixesha elizayo, inqanaba lobuchwepheshe bemizi-mveliso liya kuphuculwa, ukusetyenziswa kwe-TPU kuya kuqhubeka.
Zithini izicelo zangoku zezixhobo zeTPU kwinkampani yethu?
Njengoko iimoto zidlala indima ebalulekileyo ebomini bethu, imfuno yokhuseleko lwezithuthi phakathi kwabanini beemoto nayo iyanda. Ifilimu yokukhusela ipeyinti yezinto zeTPU sisisombululo esifanelekileyo sokujongana nale mfuno.
Enye yeempawu zefilimu yokukhusela ipeyinti yeTPU kukumelana kwayo nokukrazula, okunokumelana ngempumelelo nempembelelo yezinto ezibukhali ezifana negrabile kunye nesanti endleleni, kwaye kukhusele umzimba kwimikrwelo kunye nokuqhekeka.
