I-TPU yenziwe ngani? - Ukuqonda okujulile kwama-thermoplastic polyurethane elastomers
I-Thermoplastic Polyurethane Elastomer (TPU) iyimpahla ye-polymer ene-elasticity ephezulu, ukumelana nokuhuzuka, uwoyela namafutha, kanye nezindawo zokulwa nokuguga. Ngenxa yokusebenza kwayo okuphezulu, i-TPU isetshenziswa kabanzi ezimbonini ezahlukahlukene, kusukela ezintweni zezicathulo, amacala okuvikela emikhiqizo kagesi kuya ezingxenyeni zemishini yezimboni, i-TPU inezinhlelo eziningi zokusebenza.
Isakhiwo esiyisisekelo nokuhlukaniswa kwe-TPU
I-TPU iyi-linear block copolymer, ehlanganisa izingxenye ezimbili: ingxenye eqinile nengxenye ethambile. Ingxenye eqinile ngokuvamile yakhiwa i-disocyanate ne-chain extender, kuyilapho ingxenye ethambile yakhiwe nge-polyether noma i-polyester diol. Ngokulungisa isilinganiso sezingxenye eziqinile nezithambile, izinto ze-TPU ezinobunzima obuhlukile nokusebenza zingatholakala. Ngakho-ke, i-TPU ingahlukaniswa ngezigaba ezintathu: i-polyester TPU, i-polyether TPU ne-polycarbonate TPU.

I-Polyester TPU: Ngokumelana okuhle kakhulu kukawoyela kanye nokumelana namakhemikhali, imvamisa isetshenziswa ekukhiqizeni amapayipi ezimboni, izimpawu nezingxenye zezimoto.
I-TPU yohlobo lwe-Polyether: Ngenxa yokumelana kwayo ne-hydrolysis engcono kanye nokusebenza kwezinga lokushisa eliphansi, ivame ukusetshenziswa emkhakheni wezinto zezicathulo, amadivaysi ezokwelapha kanye nezintambo nezintambo.
I-Polycarbonate TPU: ukuhlanganisa izinzuzo ze-polyester ne-polyether TPU, inomthelela ongcono wokumelana nokubonakala, futhi ifanele imikhiqizo esobala enezidingo eziphezulu.

Izici ze-TPU nezinzuzo zohlelo lokusebenza
I-TPU ihlukile kwezinye izinto eziningi ezinezakhiwo zayo ezihlukile. Lezi zakhiwo zihlanganisa ukumelana nokuhuzuka okuphezulu, amandla amahle kakhulu emishini, ukunwebeka okuhle kanye ne-transparency.TPU ephezulu futhi inokumelana okuhle kakhulu nowoyela, izinyibilikisi namazinga okushisa aphansi. Lezi zinzuzo zenza i-TPU ibe into efanelekile yemikhiqizo edinga kokubili ukuguquguquka namandla.

Ukumelana nemihuzuko nokunwebeka: I-TPU imelana nokuhuzuka okuphezulu kanye nokunwebeka okuhle kuyenza ibe into ekhethwayo emikhiqizweni efana namasoli ezicathulo, amathayi namabhande okuthutha.
Ukumelana namakhemikhali namafutha: Ezimbonini zamakhemikhali nezemishini, i-TPU isetshenziswa kakhulu ezingxenyeni ezinjengamapayipi, ama-seal kanye nama-gaskets ngenxa yokumelana nowoyela kanye ne-solvent.
Ukucaca okuphezulu: I-TPU esobala isetshenziswa kabanzi ezimweni zokuvikela zemikhiqizo ye-elekthronikhi namadivayisi wezokwelapha ngenxa yezakhiwo zayo ezinhle kakhulu zokubuka.

Inqubo yokukhiqiza kanye nomthelela wemvelo we-TPU
Inqubo yokukhiqiza ye-TPU ikakhulukazi ihlanganisa ukukhishwa, ukubumba umjovo kanye nezindlela zokubumba igalelo, okunquma isimo nokusebenza komkhiqizo wokugcina. Ngenqubo ye-extrusion, i-TPU ingenziwa amafilimu, amapuleti namashubhu; ngenqubo yokubumba umjovo, i-TPU ingenziwa ibe yizimo eziyinkimbinkimbi zezingxenye; ngenqubo yokubumba igalelo, ingenziwa ibe yimikhiqizo ehlukahlukene engenalutho.
Ngokombono wezemvelo, i-TPU iwukusetshenziswa kabusha kwe-thermoplastic impahla, ngokungafani nama-elastomer endabuko e-thermoset, i-TPU isengancibilika futhi icutshungulwe kabusha ngemva kokushisisa. Lesi sici sinikeza i-TPU inzuzo ekwehliseni imfucuza kanye nokwehlisa ukukhishwa kwekhabhoni. Ngesikhathi sokukhiqiza nokusetshenziswa, kudinga ukunakwa emthelela wawo ongaba khona kwezemvelo, njengokukhishwa kwe-volatile organic compound (VOC) okungase kwenziwe ngesikhathi sokucutshungulwa.
Ukubukeka kwemakethe ye-TPU kanye nentuthuko yenkambiso
Ngesidingo esikhulayo sokusebenza okuphezulu, izinto zokwakha ezinobungani kwemvelo, umbono wemakethe we-TPU ubanzi kakhulu. Ikakhulukazi emkhakheni wezicathulo, imikhiqizo kagesi, imboni yezimoto kanye nemishini yezokwelapha, ukusetshenziswa kwe-TPU kuzonwetshwa. Ngokuzayo, ngokuthuthukiswa nokusebenzisa i-TPU esekelwe ku-bio kanye ne-TPU eyonakalisayo, ukusebenza kwemvelo kwe-TPU kulindeleke ukuthi kuthuthukiswe nakakhulu.
Kafushane, i-TPU iyimpahla ye-polymer enokunwebeka namandla, futhi ukumelana kwayo okuhle kakhulu nokuhuzuka, ukumelana namakhemikhali nokusebenza kokucubungula kuyenza ingakwazi ukushintshwa ezimbonini eziningi. Ngokuqonda ukuthi “i-TPU yenziwe ngani”, singakwazi ukubamba kangcono amandla nesiqondiso sale nto ekuthuthukisweni okuzayo.
