Kedu ihe eji eme TPU? -Nghọta miri emi nke thermoplastic polyurethane elastomers
Thermoplastic Polyurethane Elastomer (TPU) bụ ihe eji eme ihe na-emepụta ihe na-agbanwe agbanwe, na-eguzogide abrasion, mmanụ na griiz, na mgbochi ịka nká. N'ihi arụmọrụ ya dị elu, TPU na-ejikarị arụ ọrụ dị iche iche, site na akpụkpọ ụkwụ akpụkpọ ụkwụ, ihe nchebe maka ngwaahịa eletrọnịkị na akụkụ ngwá ọrụ mmepụta ihe, TPU nwere ọtụtụ ngwa ngwa.
Ntọala ntọala na nhazi nke TPU
TPU bụ copolymer ngọngọ linear, nke nwere akụkụ abụọ: akụkụ siri ike na akụkụ dị nro. Akụkụ siri ike na-abụkarị diisocyanate na ihe ndọtị agbụ, ebe akụkụ dị nro bụ polyether ma ọ bụ polyester diol. Site n'ịgbanwe nha nke akụkụ siri ike na nke dị nro, enwere ike nweta ihe TPU nwere ike na arụmọrụ dị iche iche. Ya mere, TPU nwere ike kewaa atọ: polyester TPU, polyether TPU na polycarbonate TPU.

Polyester TPU: Site na nguzogide mmanụ dị mma na nguzogide kemịkalụ, a na-ejikarị ya na-emepụta ọkpọkọ ụlọ ọrụ, akara na akụkụ ụgbọ ala.
Ụdị TPU nke Polyether: N'ihi nguzogide hydrolysis ya dị mma na ịrụ ọrụ dị ala, a na-ejikarị ya eme ihe na akpụkpọ ụkwụ akpụkpọ ụkwụ, ngwaọrụ ahụike na wires na eriri.
Polycarbonate TPU: ijikọta uru nke polyester na polyether TPU, ọ na-enwe mmetụta dị mma na nkwụsi ike na nghọta, ọ dịkwa mma maka ngwaahịa transperent nwere nnukwu ihe achọrọ.

Njirimara TPU na uru ngwa
TPU pụtara n'ọtụtụ ihe ndị ọzọ nwere njirimara ya pụrụ iche. Ihe ndị a na-agụnye nguzogide abrasion dị elu, ike ọrụ dị mma, ezigbo elasticity na nnukwu nghọta.TPU nwekwara ezigbo nguzogide mmanụ, ihe mgbaze na obere okpomọkụ. Uru ndị a na-eme ka TPU bụrụ ihe dị mma maka ngwaahịa na-achọ ma mgbanwe na ike.

Mgbochi abrasion na elasticity: TPU's high abrasion resistance na ezigbo mma na-eme ka ọ bụrụ ihe a na-ahọrọ maka ngwaahịa dị ka akpụkpọ ụkwụ akpụkpọ ụkwụ, taya na eriri ebu.
Kemịkalụ na mmanụ na-eguzogide: N'ime ụlọ ọrụ kemịkalụ na igwe, a na-ejikarị TPU eme ihe na akụkụ ndị dị ka hoses, akàrà na gaskets n'ihi mmanụ na ihe mgbaze ya.
Ngosipụta dị elu: A na-eji TPU transperent eme ihe n'ọtụtụ ebe n'ọnọdụ nchebe maka ngwaahịa eletrọnịkị na ngwaọrụ ahụike n'ihi ọmarịcha ngwa anya ya.

Usoro mmepụta na mmetụta gburugburu ebe obibi nke TPU
Usoro mmepụta nke TPU tumadi gụnyere extrusion, injection ịkpụzi na ịfụ ụzọ ịkpụzi, nke na-ekpebi ụdị na arụmọrụ nke ikpeazụ ngwaahịa. Site na usoro extrusion, TPU nwere ike ime fim, efere na tubes; site na usoro ịkpụzi injection, TPU nwere ike mee ka ọ bụrụ akụkụ dị mgbagwoju anya nke akụkụ; site na usoro ịkpụzi ihe, enwere ike ịme ya ka ọ bụrụ ngwaahịa dị iche iche oghere.
Site n'echiche gburugburu ebe obibi, TPU bụ ihe thermoplastic nwere ike ịmegharị, n'adịghị ka thermoset elastomers omenala, TPU ka nwere ike gbazee ma megharịa ya mgbe kpochara. Njirimara a na-enye TPU uru n'ibelata mkpofu na ibelata ikuku carbon. N'oge mmepụta na ojiji, ọ dị mkpa ka a kwụọ ụgwọ maka mmetụta gburugburu ebe obibi ya nwere ike ime, dị ka ihe ọkụkụ na-agbanwe agbanwe (VOC) nke enwere ike ịmepụta n'oge nhazi.
Echiche ahịa TPU na mmepe mmepe
Site na mmụba na-arịwanye elu maka ịrụ ọrụ dị elu, ihe omume enyi na gburugburu ebe obibi, echiche ahịa maka TPU dị nnọọ ukwuu. Karịsịa na ngalaba akpụkpọ ụkwụ, ngwaahịa eletrọnịkị, ụlọ ọrụ ụgbọ ala na ngwaọrụ ahụike, a ga-agbasawanye ngwa nke TPU. N'ọdịnihu, site na mmepe na ntinye nke TPU dabeere na bio na TPU na-emebi emebi, a na-atụ anya ka arụ ọrụ gburugburu ebe obibi nke TPU dịkwuo mma.
Na nchịkọta, TPU bụ ihe eji eme ihe na-emepụta ihe na-agbanwe agbanwe na ike, yana nguzogide abrasion ya dị mma, nguzogide kemịkalụ na nhazi nhazi na-eme ka ọ bụrụ nke a na-apụghị dochie anya n'ọtụtụ ụlọ ọrụ. Site n'ịghọta "ihe TPU mere", anyị nwere ike ịmatakwu ikike na ntụziaka nke ihe a na mmepe n'ọdịnihu.
