TPU zaj duab xis, raws li cov khoom siv polymer ua haujlwm siab, ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw vim nws lub cev thiab tshuaj lom neeg tshwj xeeb. Kab lus no yuav
delve rau hauv cov ntaub ntawv muaj pes tsawg leeg, txheej txheem ntau lawm, yam ntxwv, thiab kev siv ntawmTPU zaj duab xis, coj koj taug kev kom txaus siab rau lub ntsej muag thev naus laus zis ntawm cov khoom siv no.
1. Cov khoom siv ntawm TPU zaj duab xis:
TPU zaj duab xis, tseem hu ua thermoplastic polyurethane zaj duab xis, yog cov ntaub ntawv nyias nyias ua los ntawm polyurethane ua substrate los ntawm cov txheej txheem ua haujlwm tshwj xeeb. Polyurethane yog ib
polymer tsim los ntawm cov tshuaj tiv thaiv ntawm polyols thiab isocyanates, uas muaj kev hnav zoo heev, elasticity, thiab tshuaj tiv thaiv. Txhawm rau txhim kho nws qhov kev ua tau zoo,
cov khoom siv ntxiv xws li antioxidants thiab UV absorbers kuj tau ntxiv thaum lub sij hawm tsim TPU films.
2. Cov txheej txheem ntau lawm:
Cov txheej txheem ntau lawm ntawmTPU zaj duab xisyog zoo thiab complex, feem ntau suav nrog cov kauj ruam hauv qab no:
Kev sib xyaw ua ke: Ua ntej, nyob rau hauv qhov kev txiav txim ntawm lub catalyst, polyols thiab isocyanates tau txais cov tshuaj tiv thaiv polymerization los ua polyurethane prepolymers.
Melt extrusion: Kub lub prepolymer mus rau lub xeev molten thiab ces extrude rau hauv ib zaj duab xis los ntawm lub taub hau extruder.
Txias thiab shaping: Lub extruded molten zaj duab xis yog sai txias los ntawm ib tug txias roller kom solidify thiab tsim.
Tom qab ua tiav: suav nrog txiav, winding thiab lwm cov kauj ruam, kom tau txais TPU zaj duab xis tiav.
3. Yam ntxwv:
Cov yam ntxwv ntawm TPU zaj duab xis yog lub hauv paus rau nws daim ntawv thov dav, feem ntau tshwm sim hauv cov hauv qab no:
Lub zog siab thiab elasticity: TPU zaj duab xis muaj lub zog tensile siab thiab zoo elastic rov qab muaj peev xwm, thiab tuaj yeem tiv taus sab nraud loj yam tsis muaj deformation.
Hnav tsis kam: Lub hardness saum npoo yog nruab nrab, nrog kev hnav zoo, haum rau ntau qhov chaw hnyav.
Kub ua hauj: muaj peev xwm tswj tau stability nyob rau hauv qhov kub ntawm -40 ℃ to 120 ℃.
Chemical resistance: Nws muaj qhov ua haujlwm zoo rau cov tshuaj feem ntau thiab tsis yooj yim corroded.
Moisture permeability: Nws muaj qee qib ntawm noo noo permeability thiab tuaj yeem siv rau hauv cov xwm txheej uas yuav tsum tau ua pa.
4 、 Daim ntawv thov
Vim nws qhov kev ua tau zoo heev, TPU zaj duab xis tau siv dav hauv ntau qhov chaw, suav nrog tab sis tsis txwv rau:
Kev lag luam khaub ncaws: Raws li cov ntaub rau cov khaub ncaws, nws muab lub teeb yuag, tsis muaj dej, thiab ua pa tiv thaiv txheej.
Kev Kho Mob: Cov khoom siv sab nrauv xws li cov ris tsho phais, cov khaub ncaws tiv thaiv, thiab lwm yam yog siv los ua cov khoom siv kho mob.
Cov khoom siv ua kis las: siv los tsim cov khau kis las, hnab, thiab lwm yam khoom siv kis las, muab kev ruaj khov thiab kev nplij siab.
Automotive kev lag luam: Raws li cov khoom siv kho kom zoo nkauj sab hauv, nws tuaj yeem txhim kho kev nplij siab thiab kev zoo nkauj ntawm lub tsheb ib puag ncig.
Lub tsev teb: siv rau cov ntaub ntawv ru tsev, cov khaubncaws sab nraud povtseg, thiab lwm yam, txhawm rau txhim kho huab cua tiv thaiv thiab lub zog ua haujlwm ntawm lub tsev.
Raws li cov ntsiab lus, raws li cov khoom siv ntau yam, TPU zaj duab xis tau siv ntau thiab ntau dua hauv cov neeg niaj hnub no. Nws cov ntaub ntawv muaj pes tsawg leeg yog tshwj xeeb, ntau lawm txheej txheem
muaj kev vam meej, thiab cov yam ntxwv ntawm cov khoom muaj ntau haiv neeg. TPU zaj duab xis, nrog rau nws qhov tshwj xeeb zoo, tau ua kom pom qhov tsis muaj txiaj ntsig ntawm ob qho tib si hauv lub neej txhua hnub thiab kev ua haujlwm siab.
