Solvent-Yakavakirwa TPU inonamira yakanaka viscosity
nezve TPU
TPU (thermoplastic polyurethanes) inovhara mukaha wezvinhu pakati pemarabha nemapurasitiki. Huwandu hwayo hwezvinhu zvemuviri hunoita kuti TPU ishandiswe sese ari maviri rabha yakaoma uye yakapfava engineering thermoplastic.TPU yakawana kushandiswa kwakapararira uye mukurumbira muzviuru zvezvigadzirwa, nekuda kwekusimba kwazvo, kupfava uye kuva nemavara pakati pezvimwe zvakanaka. Mukuwedzera, ivo vari nyore kugadzirisa.
Sechinhu chiri kusimukira chepamusoro-tekinoroji uye nharaunda-inoshamwaridzika zvinhu, TPU ine zvinhu zvakawanda zvakanaka senge kuomarara kwakakura, kusimba kwemagetsi, kutonhora kwakanyanya, kuita kwakanaka kwekugadzirisa, kushatisa kwezvakatipoteredza, kuramba kwemafuta, kuramba kwemvura uye kuramba mold.
Application
Zvishandiso: Solvent Adhesives, Hot-melt Adhesive Films, Footwear Adhesive.

Hwaro hwepamusoro hunoratidzwa sehukoshi hwemazuva ese uye hahufanirwe kushandiswa sekutsanangurwa.
Package
25KG / bhegi, 1000KG / pallet kana 1500KG / pallet, yakagadzirwa epurasitiki pallet
Kubata uye Kuchengeta
1. Dzivisa kufema thermal processing utsi nemhute
2. Mechanical inobata midziyo inogona kukonzera kuumbwa kweguruva. Dzivisa kufema huruva.
3. Shandisa nzira dzakakodzera dzekudzika paunenge uchibata chigadzirwa ichi kudzivirira kubhadharisa magetsi
4. Mapepa ari pasi anogona kutsvedza uye kukonzera kudonha
Mazano ekuchengeta: Kuti uchengetedze kunaka kwechigadzirwa, chengeta chigadzirwa munzvimbo inotonhorera, yakaoma. Ramba uri mumudziyo wakavharwa zvakasimba.
Notes
1. Yakashata TPU zvinhu hazvigone kushandiswa kugadzira zvigadzirwa.
2. Usati waumbwa, zvakakosha kuti uomese zvakakwana, kunyanya panguva yekuumbwa kweextrusion, kuvhuvhuta kuumbwa, uye firimu rinoputika kuumbwa, nezvinodiwa zvakasimba zvehunyoro, kunyanya mumwaka wemvura uye nzvimbo dzakakwirira dzemvura.
3. Panguva yekugadzira, chimiro, compression ratio, groove deep, uye aspect ratio L/D ye screw inofanira kutariswa zvichienderana nehunhu hwezvinhu. Injection molding screws inoshandiswa kuumba jekiseni, uye extrusion screws inoshandiswa kuextrusion.
4. Zvichienderana nekuyerera kwezvinhu, funga nezve mold chimiro, saizi yeglue inlet, saizi yenozzle, inoyerera chiteshi chimiro, uye chinzvimbo chechiteshi chekuburitsa.
