Akụkọ - Kedu ka esi ebelata ike ma welie nguzogide abrasion nke TPU Granule?

Thermoplastic Polyurethane (TPU) bụ ihe na-agbanwe agbanwe mara maka ịdịte aka na nkwụghachi. Otú ọ dị, na ụfọdụ ngwa, enwere ike ịdị mkpa ibelata ike nke granules TPU ka ọ na-akwalite nguzogide abrasion n'otu oge.

Atụmatụ iji nweta belata ike nke TPU ma melite nguzozi nguzogide abrasion.

1. Na-ejikọta ya na ihe ndị dị nro

Otu n'ime ụzọ kachasị mfe iji belata ike TPU bụ site na ịgwakọta ya na ihe dị nro nke thermoplastic. Nhọrọ ndị a na-ahụkarị gụnyere TPE (Thermoplastic Elastomers) na akara ule dị nro nke TPU.

Nhọrọ nke ọma nke ihe dị nro na nha nke ejiri ya na TPU ejikọta ya nwere ike inye aka nweta ọkwa a chọrọ nke mbelata ike siri ike.

2.A Ọhụrụ Ụzọ: Na-ejikọta akụkụ TPU na Novel Soft Material Si-TPV

Na-ejikọta 85A TPU granules na SILIKE na-emepụta ihe dị nro Si-TPV (elastomer vulcanizate thermoplastic Silicone dabeere na elastomer), Usoro a na-emetụta nguzozi achọrọ n'etiti mbelata ike na ụbara abrasion, na-enweghị imebi ihe ndị ọzọ a na-achọsi ike.

Ụzọ iji belata ike nke ụmụ irighiri ihe TPU, usoro na nyocha:

Mgbakwunye 20% Si-TPV na ike nke 85A TPU na-ebelata ike ruo 79.2A

Mara:Nleba ule a dị n'elu bụ data nyocha nke ụlọ nyocha anyị, enweghị ike ịghọta dị ka ntinye nke ngwaahịa a, a ga-anwale onye ahịa dabere na nke ha.

Agbanyeghị, nnwale na oke ngwakọta dị iche iche bụ ihe a na-ahụkarị, na-achọ iji nweta nchikota kachasị mma nke ịdị nro na nguzogide abrasion.

3. Na-etinye ihe nchacha abrasion-eguzogide

Iji kwalite nkwụsi ike abrasion, ndị ọkachamara na-atụ aro itinye ihe nchacha dị ka carbon ojii, eriri iko, silicone masterbatch, ma ọ bụ silicon dioxide. Ihe ndochi ndị a nwere ike ịkwalite akụrụngwa mgbochi iyi nke TPU.

Otú ọ dị, ekwesịrị iji nlezianya tụlee ọnụọgụ na mgbasa nke ihe ndị a, n'ihi na oke oke nwere ike imetụta mgbanwe nke ihe ahụ.

4. Plasticizers na ndị na-eme ka ọ dị nro

Dị ka usoro iji belata isi ike TPU, ndị na-emepụta TPU nwere ike iji plasticizers ma ọ bụ ihe na-eme ka ọ dị nro. Ọ dị mkpa ịhọrọ plasticizer kwesịrị ekwesị nke nwere ike belata ike isi ike n'emebighị ihe mgbochi abrasion. Plasticizers ndị a na-ejikarị na TPU gụnyere dioctyl phthalate (DOP) na dictyl adipate (DOA). A ghaghị ịkpachara anya iji hụ na plasticizer ahọpụtara dakọtara na TPU na ọ naghị emetụta ihe ndị ọzọ dị ka ike nkwụsị ma ọ bụ nguzogide kemịkalụ. Tụkwasị na nke ahụ, ekwesịrị iji nlezianya chịkwaa usoro onunu ogwu nke plasticizers iji nọgide na-enwe nguzozi achọrọ.

5. Ntugharị dị mma na nhazi nhazi

Ịkwado extrusion na nhazi paramita dị mkpa iji nweta nchikota achọrọ nke mbelata ike siri ike na nkwalite nguzogide abrasion. Nke a na-agụnye ịgbanwe paramita dị ka okpomọkụ, nrụgide, na ọnụego jụrụ oyi n'oge extrusion.

Okpomọkụ extrusion dị ala na iji nlezianya mee ka ọ dị jụụ nwere ike iduga TPU dị nro ma na-ebuli mgbasawanye nke ihe ndị na-eguzogide abrasion.

6. Usoro nhazi mgbe emechara

Usoro nhazi mgbe emechara dị ka mgbakasị ahụ, ịgbatị, ma ọ bụ ọbụna ọgwụgwọ elu nwere ike ịkwalite nguzogide abrasion na-emebighị ike.

Annealing, karịsịa, nwere ike imeziwanye usoro kristal nke TPU, na-eme ka ọ bụrụ ihe na-eguzogide ọgwụ na iyi.

Na mmechi, imezu nguzozi siri ike nke ike TPU belatara yana nguzogide abrasion ka mma bụ usoro nwere ọtụtụ akụkụ. Ndị na-emepụta TPU nwere ike itinye nhọrọ ihe, ngwakọta, ihe na-eguzogide abrasion, plasticizers, Softening Agents, na njikwa kpọmkwem nke extrusion paramita iji mezie ihe onwunwe iji kwekọọ na ihe pụrụ iche nke ngwa enyere.

Nke a bụ ihe ịchọrọ usoro mmeri nke na-ebelata ike ike nke akụkụ TPU ma kwalite nguzogide abrasion!
