4. Hardness thiab mechanical zog:
- Lub hardness yog 60 ± 2 Ntug A, nrog rau kev yooj yim thiab lub zog.
- Lub zog tensile yog 7 MPa, qhia muaj zog tensile kuj.
- 100% modulus stress yog 2 MPa, 300% modulus stress yog 3 MPa, qhia txog kev ua tau zoo ntawm cov khoom nyob rau hauv txawv tensile tej yam kev mob.
- Lub elongation ntawm kev tawg yog 500%, qhia tias cov khoom muaj ductility siab heev thiab haum rau siv nyob rau hauv high-strain ib puag ncig.
5. Tear zog thiab resilience:
- Lub kaum sab xis tsim kua muag lub zog yog 12 kN / m, uas qhia tau zoo tsim kua muag.
- Lub resilience yog 50%, uas yog tsim rau cov xwm txheej ntawm daim ntawv thov uas yuav tsum tau muaj qee yam kev ua haujlwm resilience.
6. Ceev:
- Ntawm 25 degree, qhov ceev yog 1.11 g / cm³, uas yog tsim rau kev tsim khoom hnyav thiab muaj zog.

Daim ntawv thov
Qhov no 60A hardness polyester TDI prepolymer yog tsim rau ntau hom kev lag luam, thiab cov ntawv thov tseem ceeb suav nrog:
- Cov ntsaws ruaj ruaj thiab gaskets: Vim nws lub zog tensile zoo heev thiab tsim kua muag tsis kam, nws yog qhov tsim nyog rau cov khoom sib khi uas xav tau cov khoom siv tshuab siab.
- Muaj cov rollers: siab resilience thiab nruab nrab hardness ua rau nws cov khoom zoo tagnrho rau conveyor siv rollers thiab luam ntawv xovxwm rollers.
- Kev tiv thaiv thiab cushioning pads: Lub siab elongation ntawm tawg thiab resilience ntawm cov khoom ua rau nws lug siv nyob rau hauv cov khoom siv tiv thaiv, shock absorbing pads, thiab lwm yam.
- Mould manufacturing: Lub zog siab thiab hnav tsis kam ntawm polyurethane elastomers yog tsim rau kev tsim cov pwm pwm, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas yuav tsum tau muaj qee qhov kev hloov pauv thiab tawv.
lub cev muaj zog
Lub 60A Polyether TDI prepolymer muaj lub cev zoo heev thiab cov yam ntxwv ua haujlwm
1. Zoo fluidity: Cov Cheebtsam A thiab B muaj cov viscosities nruab nrab (400 mPa·s thiab 800 mPa·s, ntsig txog) ntawm 50 degree, ua rau lawv yooj yim tuav thaum sib tov thiab pouring, nrog fluidity zoo thiab haum rau sau complex pwm.
