I-TPU yefilimu yeglasi elaminethiweyo/ifilimu yeglasi enamathelayo
Malunga ne-TPU
Ii-TPU ze-Aliphatic luhlobo oluthile lwe-thermoplastic polyurethane ezibonisa ukumelana okuphezulu kwe-UV, nto leyo ezenza zifaneleke ukusetyenziswa ngaphandle apho ukuvezwa ixesha elide elangeni kuyinto exhalabisayo.
ANgokweempawu zeekhemikhali zezinto ezidiisocyanate lipid, i-TPU inokwahlulwahlulwa ibe ngamaqela e-aromatic kunye ne-aliphatic. I-Aromatic yeyona TPU ixhaphakileyo esiyisebenzisayo (ayixhathisi ukutyhelika okanye isiphumo sokutyhelika asilunganga, asilodidi lokutya), i-aliphatic ngokubanzi isetyenziselwa ukwenza iimveliso eziphezulu. Imizekelo ibandakanya izixhobo zonyango, izixhobo ezifuna ukutyhelika okungapheliyo, njalo njalo.
Ai-liphatic yahlulwe yaba yi-polyester/polyether.
Ulwahlulo lokumelana nokutyheli: Ngokuqhelekileyo luthelekiswa nekhadi elingwevu, lahlulwe laya kumanqanaba ali-1-5. Emva kovavanyo lokumelana nokutyheli njengeSuntest, QUV okanye olunye uvavanyo lokuvezwa lilanga, thelekisa utshintsho lombala lwesampulu ngaphambi nasemva kovavanyo, umgangatho olungileyo yi-5, oko kuthetha ukuba akukho tshintsho lombala. 3 Oku kulandelayo kukutshintsha kombala okucacileyo. Ngokubanzi, i-4-5, oko kukuthi, ukutshintsha kombala kancinci, ihlangabezane nezicelo ezininzi zeTPU. Ukuba awudingi kutshintsha kombala konke konke, ngokubanzi kufuneka usebenzise i-aliphatic TPU, oko kukuthi, i-TPU engeyiyo etyheli, i-substrate ayiyo-MDI, ngokubanzi i-HDI okanye i-H12MDI, njl.njl., kwaye uvavanyo lwe-UV lwexesha elide aluyi kutshintsha kombala.

Ukuphatha kunye nokugcina
1. Kuphephe ukuphefumla umsi kunye nomphunga osebenza ngobushushu
2. Izixhobo zokuphatha oomatshini zinokubangela ukwakheka kothuli. Kuphephe ukuphefumla uthuli.
3. Sebenzisa iindlela ezifanelekileyo zokumisa umhlaba xa uphatha le mveliso ukuze uphephe ukutshaja ngombane
4. Iipellets eziphantsi zingaba zityibilizi kwaye zibangele ukuwa
Iingcebiso zokugcina: Ukuze ugcine umgangatho wemveliso, gcina imveliso kwindawo epholileyo neyomileyo. Yigcine kwisikhongozeli esivalwe kakuhle.
