Polyurethane hnav-resistant ntawv

Polyurethane hnav cov ntawv-resistant yog cov khoom siv dav hauv cov chaw muaj kev tiv thaiv, compression kuj zoo, elasticity, thiab corrosion tsis kam. Yog li, cov txheej txheem ntau lawm thiab qhov zoo ntawm cov khoom no?
Firstly, cia saib ntawm cov txheej txheem ntau lawm ntawm cov khoom siv no:
1. Cov khoom siv raw sib xyaw: sib xyaw cov ntaub ntawv nyoos xws li Polyether lossis Polyester ua ke ib qho ntawm ib qho.
2. Ntxiv cov neeg sawv cev: Ntxiv cov polyurethane ua cov neeg sawv cev thiab cov neeg sawv cev ntawm cov neeg sawv cev, thiab do tusyees.
3. Pwm npaj: Npaj cov pwm sib raug raws li qhov yuav tsum muaj thiab cov duab.
4. Sau cov pwm: ncuav cov khoom siv raw rau hauv cov npaj pwm thiab siv cov khoom siv tus kheej lub zog nthuav dav los sau tag nrho pwm.
5. Cov tshuaj tiv thaiv thiab kev kho mob: tshuaj tiv thaiv thiab kev kho tus kheej yog nqa tawm ntawm chav sov kom ua tiav hardness thiab lub zog ntawm cov khoom siv.
6. Trimming thiab txiav: Tshem tawm cov workpiece los ntawm pwm, ua cov txheej txheem kev ua tiav xws li kev txiav thiab kev txiav, thiab thaum kawg ua ntau yam duab ntawm Polyurethane Cov Ntawv.

Cia peb mus saib qhov zoo ntawm polyurethane hnav-resistant ntawv:

1. Cov khoom siv muaj zog heev: Vim nws cov khoom siv tshwj xeeb muaj pes tsawg leeg, cov ntaub ntawv no tuaj yeem tiv thaiv cov khoom hnyav thiab muaj kev sib tsoo siab hauv kev lag luam lag luam, ua rau nws muaj kev tiv thaiv zoo.

2. Lub zog compressive zoo: vim nws qhov chaw ntov siab siab thiab tawv, nws muaj lub zog ua kom muaj zog thiab muaj peev xwm tiv taus siab.

3. Cov ntaub ntawv me me: Cov khoom siv no tseem muaj qee qhov kev cuam tshuam, nws tseem tuaj yeem nqus tau qee lub luag haujlwm thaum ua kom muaj kev ntseeg siab Cov.

4. Muaj zog corrosion resistance: vim nws cov yam ntxwv ntawm cov kua qaub thiab alkali tsis kam, nws tuaj yeem ua kom zoo tsis txhob ua rau corroded los ntawm tshuaj lom neeg, ua rau nws muaj zoo corrosion corrosion.

Raws li polyurethane khoom tsim khoom lag luam nrog ze li ntawm 20 xyoo ntawm kev paub dhau los, peb tau txais txiaj ntsig zoo ntawm polyurethane hnav rau polyurethane cov ntaub ntawv thiab daws ntau yam ntawm lawv cov teeb meem.
