Nkhani - Momwe mungachepetsere kuuma ndikukulitsa abrasion Resistance ya TPU Granule?

Thermoplastic Polyurethane (TPU) ndi chinthu chosunthika chomwe chimadziwika chifukwa chokhazikika komanso cholimba.Komabe, muzinthu zina, pangakhale kufunika kochepetsa kuuma kwa ma granules a TPU kwinaku mukukulitsa kukana kwa abrasion.

Njira zokwaniritsira kuchepetsa kuuma kwa TPU ndikuwongolera bwino kukana kwa abrasion.

1. Kuphatikiza ndi Zida Zofewa

Imodzi mwa njira zowongoka kwambiri zochepetsera kuuma kwa TPU ndikuphatikiza ndi zinthu zofewa za thermoplastic.Zosankha zodziwika bwino zimaphatikizapo TPE (Thermoplastic Elastomers) ndi magiredi ochepera a TPU.

Kusankha mosamala zinthu zofewa komanso chiŵerengero chomwe zimasakanizidwa ndi TPU kungathandize kukwaniritsa mulingo wofunikira wochepetsera kuuma.

2.Njira Yatsopano: Kuphatikiza Tinthu ta TPU ndi Novel Soft Material Si-TPV

Kuphatikiza ma granules a 85A TPU ndi SILIKE adayambitsa soft Material Si-TPV (dynamic vulcanizate thermoplastic Silicone-based elastomer), Njira iyi imakhudza kukhazikika komwe kumafunikira pakati pa kuchepetsa kuuma ndi kuchulukitsidwa kwa ma abrasion, osasokoneza zinthu zake zina zofunika.

Njira yochepetsera kuuma kwa tinthu ta TPU, Fomula ndi Kuwunika:

Kuphatikiza kwa 20% Si-TPV ku Kuuma kwa 85A TPU kumachepetsa kuuma mpaka 79.2A

Zindikirani:Zomwe zili pamwambazi ndizoyesa deta yathu ya labotale, ndipo sitingamvetsetse ngati kudzipereka kwa mankhwalawa, kasitomala ayenera kuyesedwa potengera zomwe akufuna.

Komabe, Kuyesa kophatikizana kosiyanasiyana kumakhala kofala, kulinga kukwaniritsa kuphatikiza koyenera kwa kufewa ndi kukana abrasion.

3. Kuphatikiza Ma Abrasion-Resistant Fillers

Kuti muwonjezere kukana kwa abrasion, akatswiri amalimbikitsa kuphatikiza zodzaza ngati kaboni wakuda, ulusi wagalasi, silicone masterbatch, kapena silicon dioxide.Ma Filler awa amatha kulimbikitsa katundu wa TPU wokana kuvala.

Komabe, kuganiziridwa mozama kuyenera kuganiziridwa pa kuchuluka ndi kubalalitsidwa kwa zodzaza izi, chifukwa kuchuluka kochulukirapo kungakhudze kusinthasintha kwa zinthuzo.

4. Plasticizers ndi Ofewetsa Agents

Monga njira yochepetsera kuuma kwa TPU, Opanga TPU atha kugwiritsa ntchito mapulasitiki kapena zofewa.Ndikofunika kusankha pulasitiki yoyenera yomwe ingachepetse kuuma popanda kusokoneza kukana kwa abrasion.Mapulasitiki omwe amagwiritsidwa ntchito ndi TPU amaphatikizapo dioctyl phthalate (DOP) ndi dioctyl adipate (DOA).Chisamaliro chiyenera kuchitidwa kuti pulasitiki yosankhidwayo igwirizane ndi TPU ndipo sichimakhudza zinthu zina monga kulimba kwamphamvu kapena kukana mankhwala.Kuphatikiza apo, Mlingo wa ma plasticizer uyenera kuyendetsedwa mosamala kuti ukhalebe wokwanira.

5. Fine-Ikukonzekera Extrusion ndi Processing magawo

Kusintha ma extrusion ndi ma process a parameter ndikofunikira kwambiri pakukwaniritsa kuphatikiza komwe kumafunikira pakuchepetsa kuuma komanso kukulitsa kukana kwa abrasion.Izi zikuphatikizapo kusintha magawo monga kutentha, kuthamanga, ndi kuzizira panthawi ya extrusion.

Kutentha kwapang'onopang'ono komanso kuziziritsa mosamalitsa kumatha kupangitsa kuti TPU ikhale yofewa ndikukhathamiritsa kubalalitsidwa kwa zodzaza zosamva ma abrasion.

6. Njira Zopangira Pambuyo

Njira zopangira pambuyo pokonza monga kutsekereza, kutambasula, kapena ngakhale mankhwala opangira pamwamba amatha kupititsa patsogolo kukana kwa abrasion popanda kusokoneza kuuma.

Annealing, makamaka, imatha kukonza mawonekedwe a crystalline a TPU, ndikupangitsa kuti ikhale yosamva kuvala ndi kung'ambika.

Pomaliza, kukwaniritsa kusamalidwa bwino kwa kuuma kwa TPU komanso kulimba kwa abrasion ndi njira yochulukirapo.Opanga a TPU amatha kupititsa patsogolo kusankha kwazinthu, kuphatikiza, zodzaza zosamva ma abrasion, mapulasitiki, Ma Softening Agents, ndikuwongolera moyenera magawo a extrusion kuti asinthe bwino zinthuzo kuti zigwirizane ndi zofunikira za pulogalamu yomwe wapatsidwa.

Izi ndi zomwe mukufunikira Fomu Yopambana yomwe imachepetsa Kuuma kwa TPU Particle ndikuwonjezera Kukaniza kwa Abrasion!
