Nqe lus piav qhia: polyurethane elastomeric yog cov khoom siv tshiab ntawm cov khoom siv hluavtaws ntawm cov roj hmab thiab yas. Nws muaj ob qho tib si siab zog ntawm cov yas thiab siab elasticity ntawm roj hmab. Nws cov yam ntxwv yog:

1. Muaj ntau yam hardness. Nws tseem muaj roj hmab elongation thiab resilience ntawm siab hardness. Cov polyurethane elastomeric muaj qhov nyuaj ntawm Shore A 10-D80.

2. Lub zog muaj zog. Ntawm cov roj hmab hardness, lub zog tensile, lub zog tsim kua muag thiab lub peev xwm nqa tau ntau dua li cov khoom siv roj hmab dav dav. Thaum lub siab hardness, nws lub zog cuam tshuam thiab lub zog flexural yog ntau dua li cov khoom siv yas.

3. hnav-resistant. Nws hnav tsis kam yog qhov zoo heev, feem ntau nyob rau hauv thaj tsam ntawm 0.01-0.10cm3/1.61km, li ntawm 3-5 npaug tshaj li cov khoom siv roj hmab.

4. Roj resistant. Cov polyurethane elastomeric yog ib qho polar polymer compound uas tsis tshua muaj affinity nrog cov roj ntxhia uas tsis yog-polar thiab tsis tshua muaj eroded hauv cov roj thiab cov roj siv tshuab.

5. Kev tiv thaiv zoo rau oxygen thiab ozone.

6. Kev ua tau zoo ntawm kev vibration absorption, tuaj yeem ua damping thiab buffering. Hauv kev tsim pwm kev lag luam, nws hloov cov roj hmab thiab cov springs.

7. Muaj qhov ua tau zoo ntawm qhov kub thiab txias.

8. Kev tiv thaiv hluav taws xob. Polyurethane muaj zog heev tiv taus hluav taws xob hluav taws xob thiab muaj kev ua tau zoo ntawm 10-10 deg hluav taws xob koob.

9. Nrog zoo machining kev ua tau zoo.

Lub polyurethane roj foob, hydraulic roj foob yog tsim los ntawm kev txhaj tshuaj molding nrog zoo TPU. Nws yog qhov ua tau zoo heev ntawm cov tshuaj erode resistant, impregnant resistant, ozone resistant, hluav taws xob resistant, laus resistant, hydrolyze resistant, thiab siab tensile lub zog, tsim kua muag resistant, siab cuam tshuam resistant, siab khoov lub zog thiab tsis tshua muaj compression teeb thiab lwm yam. 5 ntau ntau dua li cov roj hmab ntshiab huv, thiab cov roj resistant yog 3-5 ntau ntau tshaj NBR roj hmab, thiab muaj elasticity siab 65 feem pua nrog cov compression tseem ceeb ntawm qhov kub thiab txias. Kev kho dua tshiab ntawm qhov tawv tawv ntawm 85-92 ntug dej A, viscidity zoo heev nrog cov khoom siv hlau, nws yog cov khoom siv macromolecule tshiab nrog kev hloov pauv sai tam sim no. Siv rau txhua yam hydraulic foob, nplhaib thiab gasket rau tub rog, kuv, roj teb, tshuaj, luam ntawv, xuas nrig ntaus, ntawv ua, kiv, nws pib muaj rau roj, huab cua thiab dej nrog zoo tensile zog, qis compressive deformation, resistant kub thiab txias kub.
