Nhau - Maitiro Ekudzikisa kuomesa uye kusimudzira iyo Abrasion kuramba granule yeTPU?

Thermoplastic Polyurethane (TPU) chinhu chose chinozivikanwa chinozivikanwa nekusagadzikana kwavo uye kusimba. Nekudaro, mune zvimwe zvekushandisa, panogona kunge paine kudiwa kwekuderedza kuomarara kweTPU granules nguva panguva imwe chete ichishandura abrasion kuramba.

Maitiro ekuzadzisa kuderedza kuomarara kweTPU uye kunatsiridza abrasion kuramba mwero.

1. Kusanganisa nezvinhu zvinodzvara

Imwe yenzira dzakakwirira kwazvo dzekudzikisa tpu kuomarara ndeyekuzvisanganisa neyakainakidza thermoplastic zvinyorwa. Sarudzo dzakajairika dzinosanganisira tpe (thermoplastic elastoromers) uye nyora mamakisi eTPU.

Kusarudzwa nokungwarira kwezvinhu zvekunyaradza uye iyo ratio iyo iyo inosanganiswa neTPU inogona kubatsira kuwana iyo yaunoda mwero wekudzikama

2.A nzira nyowani: Kubatanidza TPU zvimedu neNovel zvinyoro nyoro si-TPV

Kusanganisa iyo 85A tpu granules neSilkey yakatanga zvinyoro-nyoro

Nzira yekudzikisa kuomarara kweTPU zvikamu, formula uye kuongorora:

Kuwedzera kwe20% si-tPV kune kuomarara kwe85 tpu inoderedza kuomarara kusvika ku79.2a

ONA:Iyo yepamusoro test data ndeye yedu LAB inoshanda yeTest data, uye haigone kunzwisiswa sekuzvipira kwechigadzirwa ichi, mutengi anofanira kuedzwa kubva pane yavo chaiyo.

Nekudaro, kuyedza nehurongwa hwakasiyana-siyana hwakajairika, chinangwa kuti uwane musanganiswa wakakwana wekupfava uye kupokana naAbrasion.

3. Kupinza Abraasion-anoramba mafirita

Kuti uwedzere kusimudzira kurwisa, nyanzvi dzinoratidza kubatanidza mahonyeti akanyatsoita kunge kabhoni nhema, girazi machira, silicone masterbatch, kana silicon dioxide. Aya mafirita anogona kusimudzira iyo TPU yaTpu yekupfeka-kuramba zvinhu.

Nekudaro, kunyatsofungisisa kunofanirwa kupihwa kuwanda uye kupararira kweaya mafirita, seyakawandisa inogona kukanganisa kuchinja kwezvinhu.

4. Plastictizers uye zvinyoro-nyoro vamiririri

Senzira yekudzikisa TPU kuomesa, vagadziri veTPU vanogona kushandisa mapurasitiki kana vanyoro nyoro. Izvo zvakakosha kusarudza iyo yakakodzera plasticzer iyo inogona kuderera kuomesa pasina kukanganisa kuramba basa. Zvakajairika mapurasitiki anoshandiswa neTPU anosanganisira dioctyl Phthalate (DOP) uye Dioctyl Adipate (DOA). Chenjera chinofanira kutorwa kuti chive nechokwadi chekuti plasticzer yakasarudzwa inoenderana neTPU uye haina kuita zvakaipa zvimwe zvinhu zvakadai seinesimba kana kurwisa kwemakemikari. Uye zvakare, iyo dosage yemapurasitiki inofanirwa kuve yakadzorwa zvine hunyanzvi kuchengetedza iyo yaunoda mwero.

5. Yakanaka-kuitisa kubuda uye kugadzirisa paramita

Kugadzirisa Extrusion uye kugadzirisa ma parmeter ndeye pivotal mukuzadzisa iyo yaunoda musanganiswa wekuomerwa kwakaderera uye kuvandudza kupokana neabrasion. Izvi zvinosanganisira kugadzirisa paramita senge tembiricha, kumanikidzwa, uye kutonhora mitengo panguva yekutsvagira.

Kudzikira kwekunze tembiricha uye kutonhora kwekungwarira kunogona kutungamira kuSFTER TPU apo optimizing kupararira kweanopatsanurana kweabrasion.

6. Post-kugadzirisa maitiro

Post-kugadzirisa maitiro sekutsamwisa, kutambanudza, kana kunyange kurapwa kwekunakisa kunogona kuwedzera kuwedzera kurwisa brasion kuramba pasina kukanganisa kuomarara.

Annealing, kunyanya, anogona kuvandudza crystalline chimiro cheTPU, ichiita kuti ive zvakanyanya kupfeka nekubvarura.

Mukupedzisa, kuzadzisa chiyero chakasimba cheTPU kuomarara kweTPU uye kwakagadziridzwa kupokana neabrasion chiitiko chakawanda. Vagadziri veTPU vanogona kuwedzera kusarudzwa kwemidziyo, kusanganisa, vafiripiti-vanopenga, vanopfava, vakanyorova vamiriri, uye vakanyorova masaga ezvinyorwa kuti vabatwe nezvinhu zvakasarudzika zvekushandisa zvakapihwa.

Izvi ndizvo zvauri kuda fomu yekukunda iyo inoderedza TPU STUPLE kuomarara uye kunatsiridza kuramba kupokana!
