Nhau - Maitiro ekudzikisa kuoma uye kuwedzera abrasion Resistance yeTPU Granule?

Thermoplastic Polyurethane (TPU) chinhu chinoshandiswa zvakasiyana-siyana chinozivikanwa nekusimba uye kusimba.Nekudaro, mune mamwe maapplication, panogona kunge paine kudikanwa kwekudzikisa kuomarara kweTPU granules panguva imwe chete ichiwedzera abrasion kuramba.

Matanho ekuwana kuderedza kuoma kweTPU uye kugadzirisa abrasion kuramba chiyero.

1. Kusanganisa neZvinyoro Zvinyoro

Imwe yedzakanyanya kujeka nzira dzekudzikisa kuomarara kweTPU ndeyekuisanganisa neyakapfava thermoplastic zvinhu.Sarudzo dzakajairika dzinosanganisira TPE (Thermoplastic Elastomers) uye akapfava mamakisi eTPU.

Kungwarira kusarudzwa kwezvinhu zvakapfava uye chiyero painosanganiswa neTPU inogona kubatsira kuzadzisa yaidiwa nhanho yekuderedza kuomarara.

2.Nzira Itsva: Kubatanidza TPU Zvimedu neNovel Soft Material Si-TPV

Kubatanidza iyo 85A TPU granules neSILIKE yakatanga yakapfava Material Si-TPV (yakasimba vulcanizate thermoplastic Silicone-based elastomer), Iyi nzira inorova chiyero chinodiwa pakati pekuderedza kuoma uye kuwedzera abrasion kuramba, pasina kukanganisa zvimwe zvayo zvinodiwa.

Nzira yekudzikisa kuoma kweTPU zvimedu, Formula uye Ongororo:

Kuwedzerwa kwe20% Si-TPV kune Kuoma kwe85A TPU kunoderedza kuoma kusvika ku79.2A

Cherechedza:Iyo iri pamusoro bvunzo data ndeye yedu lab inoshanda yekuyedza data, uye haigone kunzwisiswa sekuzvipira kwechigadzirwa ichi, mutengi anofanirwa kuyedzwa zvichibva pane yavo chaiyo.

Nekudaro, Kuedza neakasiyana kusanganisa reshiyo kwakajairika, ichivavarira kuwana yakakwana musanganiswa wekupfava uye kuramba abrasion.

3. Kubatanidza Abrasion-Resistant Fillers

Kuwedzera abrasion kuramba, nyanzvi dzinokurudzira kubatanidza chaiwo mafirita senge kabhoni nhema, girazi fibers, silicone masterbatch, kana silicon dioxide.Aya maFiller anogona kusimbisa iyo TPU yekupfeka-resistance zvivakwa.

Nekudaro, kunyatsotariswa kunofanirwa kupihwa kune huwandu uye kupararira kweaya mafirita, sezvo kuwanda kwemari kunogona kukanganisa kushanduka kwechinhu.

4. Plasticizers uye Softening Agents

Senzira yekudzikisa kuoma kweTPU, TPU Vagadziri vanogona kushandisa plasticizers kana softening agents.Zvakakosha kusarudza plasticizer yakakodzera iyo inogona kuderedza kuoma pasina kukanganisa abrasion resistance.Mapurasitiki akajairika anoshandiswa neTPU anosanganisira dioctyl phthalate (DOP) uye dioctyl adipate (DOA).Kuchengetedza kunofanirwa kutorwa kuti ive nechokwadi chekuti plasticizer yakasarudzwa inoenderana neTPU uye haina kukanganisa zvimwe zvinhu zvakaita sekusimba kwesimba kana makemikari kuramba.Uye zvakare, Iyo dosage yeplasticizers inofanirwa kudzorwa zvine hungwaru kuchengetedza chiyero chinodiwa.

5. Fine-Tuning Extrusion uye Processing Parameters

Kugadzirisa extrusion uye kugadzirisa ma paramita kwakakosha mukuwana iyo inodiwa musanganiswa wekuomarara kuomarara uye nekuwedzera abrasion kuramba.Izvi zvinosanganisira kushandura paramita senge tembiricha, kudzvanywa, uye kutonhora mitengo panguva yeextrusion.

Yakadzika extrusion tembiricha uye kunyatsotonhora kutonhora kunogona kutungamira kune yakapfava TPU uku uchinatsiridza kupararira kweabrasion-resistant fillers.

6. Post-Processing Techniques

Post-processing maitiro senge annealing, kutambanudza, kana kunyangwe kurapwa kwepamusoro kunogona kuwedzera kuwedzera abrasion kuramba pasina kukanganisa kuoma.

Annealing, kunyanya, inogona kuvandudza iyo crystalline chimiro cheTPU, ichiita kuti irambe ichiramba kupfeka uye kubvarura.

Mukupedzisa, kuwana chiyero chakapfava cheyakaderedzwa TPU kuomarara uye yakagadziridzwa abrasion kuramba inzira ine mativi mazhinji.TPU Vagadziri vanogona kukwidziridza kusarudzwa kwezvinhu, kusanganisa, abrasion-resistant fillers, plasticizers, Softening Agents, uye kunyatso kudzora kweextrusion paramita kugadzirisa zvakanaka zvivakwa kuti zvienderane nezvakasarudzika zvinodiwa zvechikumbiro chakapihwa.

Izvi ndizvo zvaunoda A Winning Formula iyo inoderedza TPU Particle Kuoma uye Inovandudza Abrasion Resistance!
