Imfihlakalo ye-TPU Film: Ukwakheka, inqubo kanye nokuhlaziywa kwesicelo

Ifilimu ye-tpu, njengezinto eziphakeme ze-polymer, kudlala indima ebalulekile emikhakheni eminingi ngenxa yezakhiwo zayo ezihlukile zenyama nangamakhemikhali. Le ndatshana izokwazi

dlulela ezintweni zokwakhiwa, izinqubo zokukhiqiza, izici, kanye nokusetshenziswa kweIfilimu ye-tpu, Ukukuthatha ohambweni ukuze ukwazisa ubuhle bezobuchwepheshe balokhu okuqukethwe.

1. Izinto zokwakheka zefilimu ye-TPU:

Ifilimu ye-TPU, eyaziwa nangokuthi ifilimu ye-thermoplastic polyurethane, iyinto ethambile yamafilimu eyenziwe nge-polyurethane njengezindlela ezingezansi ngokusebenzisa amasu athile wokucubungula. Polyurethane a

I-polymer ekhiqizwa ukusabela kwama-polyols nama-isocyanates, anokumelana kahle kakhulu, ukuqina, kanye nokumelana kwamakhemikhali. Ukuze uthuthukise ukusebenza kwawo,

Izithasiselo ezisebenzayo ezifana nama-antioxidants kanye nama-UV akhunta nazo ziyangezwa ngesikhathi sokukhiqiza amafilimu we-TPU.

2. Inqubo yokukhiqiza:

Inqubo yokukhiqiza yeIfilimu ye-tpuKulungile futhi kuyinkimbinkimbi, ikakhulukazi kufaka phakathi izinyathelo ezilandelayo:

I-Aggregation Reaction: Okokuqala, ngaphansi kwesenzo se-catalyst, ama-polyols kanye nama-isocyanates abhekana nokusabela kwe-polymerization ukwenza ama-polyurethane prepolymers.

Ukukhishwa kwe-Melt: Shisisa i-prepolymer ku-molten state bese uyikhipha kwifilimu ngekhanda le-extruder.

Ukupholisa nokubumba: Ifilimu elibiwe elengeziwe liphoqelelwa ngokushesha yi-roller epholile ukuze iqinise futhi ifomu.

Ukucutshungulwa kweposi: kufaka phakathi ukusika, ukuzulazula nezinye izinyathelo, ekugcineni ukuthola ifilimu ye-TPU eqediwe.

3. Izici:

Izici zefilimu ye-TPU ziyisisekelo sohlelo lwayo olubanzi, ziboniswe ikakhulukazi ezicini ezilandelayo:

Amandla aphezulu kanye nokuqina

Gqoka ukumelana: Ubulukhuni bendawo bulinganiselwe, ngokumelana kahle nokuvimbela okuhle, kufanelekile ezindaweni ezahlukahlukene ezinokhahlo.

Ukumelana Nezinga lokushisa: Uyakwazi ukugcina ukuqina ngaphakathi kobubanzi bokushisa obungu-40 ℃ kuya ku-120 ℃.

Ukumelana kwamakhemikhali: Kunokumelana okuhle kumakhemikhali amaningi futhi akukaze kuhlungwe kalula.

Umswakama ulimele: Ine-degree ethile yokuvunyelwa komswakama futhi ingafakwa ezimweni lapho ukuphefumula kudingeka khona.

4, Isicelo

Ngenxa yokusebenza kwayo okuhle, ifilimu ye-TPU isetshenziswe kabanzi emikhakheni ehlukahlukene, kufaka phakathi kepha ayikhawulelwe ku:

Imboni yezingubo: njengendwangu yezingubo, ihlinzeka ngongqimba olungasindi, olungenamanzi futhi oluphefumulayo.

Inkambu yezokwelapha: izinto zangaphandle ezifana nezingubo zokuhlinzwa, okokuvikela izigqoko, njll. Kusetshenziselwa ukwenza amadivaysi ezokwelapha.

Imishini Yezemidlalo: Isetshenziselwa ukukhiqiza izicathulo zemidlalo, izikhwama nezinye izinto zemidlalo, ukuhlinzeka ngokuqina nenduduzo.

Imboni yezimoto: Njengezinto zokuhlobisa ezingaphakathi, ingathuthukisa induduzo nama-aesthetics wemvelo yemoto.

Inkambu Yokwakha: Isetshenziselwa izinto zophahla, izingqimba zamanzi, njll., Ukuthuthukisa ukumelana nesimo sezulu kanye nokusebenza kwamandla kwezakhiwo.

Ukufingqa, njengezinto ezisebenzayo eziningi, ifilimu ye-TPU ibilokhu isetshenziswe kabanzi emphakathini wanamuhla. Izinto zalo zokwakheka ziyizinqubo ezihlukile, zokukhiqiza

bayathuthuka, futhi izici zomkhiqizo zihlukahlukene. Ifilimu ye-TPU, ngezinzuzo zayo ezihlukile, ibonise inani elingenakufinyeleleka kuzo zombili impilo yansuku zonke nasezinkameni zobuchwepheshe obuphakeme.
