Ikhwalithi ephezuluifilimu yokuvikela upende (i-PPF)ithembele ku-Thermoplastic Polyurethane (TPU) njengezinto zayo eziyisisekelo ezibalulekile, ezinquma ukuqina kwefilimu, ubuhle bayo, kanye nokusebenza kwayo. Njengamanje, i-TPU ihlukaniswe ngokuyinhloko ngezinhlobo ze-aliphatic kanye ne-aromatic, kanti umehluko wazo oyinhloko ulele "ekumelaneni nokuphuzi." Ithebula elingezansi libonisa ngokucacile umehluko obalulekile phakathi kwezinhlobo ezimbili ze-TPU:
| Isici | I-TPU ye-Aliphatic | I-TPU Enuka Kahle |
|---|---|---|
| Isakhiwo Samakhemikhali | Ayinawo ama-benzene rings (isb., asekelwe ku-HDI), azinzile ngokwesakhiwo. | Iqukethe izakhiwo zendandatho ye-benzene (isb., ngokusekelwe ku-MDI). |
| Izici Eziyinhloko | Ukumelana okuhle kakhulu kokuphuzi: Ukumelana isikhathi eside nemisebe ye-UV, kanye nezikhathi zewaranti ezivame ukudlula iminyaka eyi-10. Isakhiwo esiqinile: Ubuningi obukhulu bokupakisha ama-molecule, okunikeza ukumelana okungcono kokuklwebheka nokuklwebheka, kanye nokuqina okuphezulu nokuthambekela. | Kuthambekele ekubeni phuzi: Amasongo e-benzene angancibilika ngaphansi kokuchayeka ku-UV, okungaholela ekubeni phuzi okubonakalayo kungakapheli iminyaka engu-3-5. Ukuguquguquka okuhle, kodwa ngokuvamile kuphansi ngamandla kanye nokumelana nokuklwebheka uma kuqhathaniswa nezinhlobo ze-aliphatic. |
| Isikhundla Semakethe | Izinto eziyisisekelo eziyinhloko ze-PPF esezingeni eliphezulu, ezinentengo ephezulu. | Izinto eziyisisekelo ezivamile ze-PPF ephakathi kuya kwephansi, zingabizi kakhulu. |
Ezinye Izigaba ze-TPU kanye Nokwakheka kwe-PPF
Ngaphandle kwezigaba ezingenhla, i-TPU ingahlukaniswa futhi ngokusekelwe esigabeni sayo esithambile ibe izinhlobo ezisekelwe ku-polyester kanye nezinhlobo ezisekelwe ku-polyester. I-TPU esekelwe ku-polyester inikeza amandla angcono, ukumelana nokuhuzuka, kanye nokumelana namafutha; I-TPU esekelwe ku-Polyether inikeza ukumelana okuphezulu kwe-hydrolysis kanye nokuguquguquka okuphansi kwezinga lokushisa. Izinto zesisekelo ze-PPF zesimanje ezisezingeni eliphezulu zivame ukusebenzisa amafomula alungiselelwe ukulinganisela lezi zakhiwo. I-PPF ephelele iyisakhiwo esinezingqimba eziningi. Ngaphandle kwengqimba yesisekelo se-TPU, ifaka:
- Isendlalelo Esinamathelayo: Siqinisekisa ukubopha okuqinile nokususwa okungenazinsalela ngaphandle kokulimaza upende wokuqala. Sidinga amandla aphezulu okubopha kanye nokumelana ne-UV. Imikhiqizo yekhwalithi ephezulu igxila nasekumelaneni nokufuduka kwe-plasticizer ukuvimbela ukwehluleka kwe-glue.
- Ingubo Ephezulu Esebenzayo: Ingqimba engaphandle, enquma ngqo ulwazi lomsebenzisi. Imisebenzi ebalulekile ifaka phakathi ukuziklwebha (ukuthembela ezibophweni ze-hydrogen ngaphakathi kwengubo ezilungisa imiklwebhe emincane ngokushisa), izakhiwo ze-hydrophobic kanye ne-oleophobic (ukwenza kube lula ukuhlanza), kanye nokunikeza imiphumela ebonakalayo njengokuqeda okucwebezelayo noma oku-matte.
Indlela Yokukhetha Nokumaketha Amathrendi
Uma ukhetha i-PPF, ngaphandle kokuqinisekisa ukusetshenziswa kwe-TPU ye-aliphatic, ungacabanga futhi ngalokhu:
- Hlola Iwaranti Esemthethweni: Imikhiqizo ye-TPU ethembekile ye-aliphatic ivame ukuza newaranti esemthethweni yeminyaka eyi-10 noma ngaphezulu, okuqinisekisa ngokusobala ukusebenza okulwa nokuphuzi.
- Gxila kubuchwepheshe be-Top Coat: I-top coat ihlobene ngqo nokungathandi amanzi, ukusebenza kahle kokuzilapha, kanye nokuphila isikhathi eside. Buza ngemisebenzi ethile ye-coat.
- Qaphela Izingibe Zentengo Ephansi: Qaphela izimangalo ze-“aliphatic TPU” ngamanani aphansi ngendlela engavamile, njengoba zingase zinganembile.
Ngokuphathelene nezitayela, ngokwenyuka kwesidingo sabathengi sekhwalithi nokuqina, i-TPU esebenza kahle kakhulu, emelelwa izinto ezifanaLINGHUA TPU uchungechunge, sekuba ukukhetha okujwayelekile emakethe.
