Nyochaa uru na ọghọm dị n'ime ihe nkedo iron core polyurethane casters

Igwe ihe nkedo nke polyurethane nke ígwè bụ ụdị nkedo nke nwere ihe polyurethane, nke a na-ejikọta ya na nkedo ígwè, isi ígwè ma ọ bụ ígwè efere efere, nke dị jụụ, dị nwayọọ arọ na nke akụ na ụba, ma dabara maka ọtụtụ ebe ọrụ.
Ọtụtụ mgbe, nha nke ihe nkedo ụlọ ọrụ dị n'etiti 4 ~ 8 sentimita (100-200mm), na wiil polyurethane bụ ihe kacha mma. Polyurethane wiil nwere elu abrasion nguzogide, a dịgasị iche iche nke mmezi arụmọrụ, iche iche nhazi ụzọ, obosara applicability, na ezigbo iguzogide mmanụ, ozone, ịka nká, radieshon, ala okpomọkụ, wdg, ezi ụda permeability, ike nrapado ike, magburu onwe biocompatibility na ndakọrịta ọbara.

A na-eji ihe nkedo polyurethane mara nke ọma site na njirimara ndị a:
1. Nnukwu nhazi nke arụmọrụ. Site na nhọrọ nke akụrụngwa ma mezie usoro, nwere ike ịdị na-agbanwe n'ime a ụfọdụ nso nke mgbanwe na a ọnụ ọgụgụ nke anụ ahụ na n'ibu arụmọrụ egosi, izute pụrụ iche chọrọ nke onye ọrụ na arụmọrụ nke ngwaahịa. Dịka ọmụmaatụ, polyurethane elastomers nwere ike ime ka ọ bụrụ ihe na-emepụta ihe na-emepụta rọba na-ebi akwụkwọ dị nro na ígwè ígwè siri ike iji gboo mkpa nke ndị ọrụ dị iche iche.
2. Nguzogide abrasion dị elu. N'ebe mmiri, mmanụ na ọnọdụ mgbasa ozi wetting ndị ọzọ na-arụ ọrụ, nkwụsị nke ihe nkedo polyurethane dị ọtụtụ ugboro ruo ọtụtụ ugboro karịa nke ihe rọba nkịtị.

3. Usoro nhazi dị iche iche na ngwa ngwa dị ukwuu. Enwere ike ịkpụzi elastomer polyurethane site na plasticizing, ngwakọta na usoro vulcanizing (na-ezo aka na MPU); enwere ike ime ya ka ọ bụrụ rọba mmiri mmiri, ịkpụzi ihe nkedo ma ọ bụ ịgbasa, ite na ịkpụzi centrifugal (na-ezo aka na CPU); Enwere ike ime ya ka ọ bụrụ ihe granular ma kpụzie ya site na injection, extrusion, calendering, ịfụ ịkpụ na usoro ndị ọzọ (na-ezo aka na CPU).
4. Na-eguzogide mmanụ, ozone, ịka nká, radieshon, okpomọkụ dị ala, nnyefe ụda dị mma, ike nrapado siri ike, ezigbo biocompatibility na ndakọrịta ọbara.

Otú ọ dị, polyurethane elastomers nwere ụfọdụ adịghị ike, dị ka elu endogenous okpomọkụ, elu okpomọkụ na-eguzogide n'ozuzu, karịsịa ọjọọ iguzogide mmiri na okpomọkụ, na-adịghị eguzogide ike pola solvents na ike acid na alkali media.
