Peb txhua tus paub tias qhov zoo ntawm cov khoom yog feem ntau txiav txim siab los ntawm cov khoom uas nws yog ua los ntawm, raws li yog lub synchronous siv.
Qhia cov yam ntxwv ntawm synchronous siv raw khoom - polyurethane:
1. Kev hnav tsis zoo: Cov hnav tsis kam ntawm polyurethane elastomer yog sib npaug, li ntawm 3 mus rau 5 npaug ntawm cov roj hmab ntuj, thiab muaj lub koob npe nrov ntawm "cov roj hmab tiv thaiv";
2. Qhov ntau ntawm hardness yog dav: qhov hardness ntau ntawm polyurethane elastomers tuaj yeem zoo ib yam li ntug dej A10, thiab qhov siab hardness tuaj yeem ncav cuag ntug dej D85. Nws txuas los ntawm hardness ntawm roj hmab mus rau hardness ntawm plastics. Dab tsi yog qhov tseem ceeb tshaj yog qhov siab hardness ntawm polyurethane elastomers. , muaj roj hmab elasticity zoo heev thiab elongation;
3. Lub zog siab: Nyob rau hauv lub hardness ntawm cov roj hmab, lub tensile thiab tearing lub zog ntawm polyurethane elastomer yog loj npaum li cas ntawm cov roj hmab feem ntau siv; nyob rau hauv lub hardness ntawm yas, nws lub zog cuam tshuam thiab khoov tuag yog siab dua cov yas. Lub ntim kuj loj dua;
4. Roj kuj: Cov roj kuj ntawm polyester polyurethane elastomer tsis tsawg tshaj li cov roj hmab nitrile, zoo ib yam li cov roj hmab polysulfide;
5. Lub peev xwm loj: Vim tias cov polyurethane elastomer tuaj yeem ua kom lub zog ntawm lub hauv paus ntawm kev tuav lub elasticity ntawm cov roj hmab, thiab yog li tau txais lub peev xwm loj;
Qhov no yog incomparable rau ib co lwm yam roj hmab
6. Kev ua tau zoo ntawm kev co zoo heev: Kev ua haujlwm ntawm polyurethane elastomer ntawm kev hloov chaw pw hav zoov qhia tau hais tias pom tseeb hysteresis xeev. Thaum lub sij hawm tus txheej txheem no, ib feem ntawm lub zog cuam tshuam los ntawm sab nraud quab yuam yog noj nyob rau hauv lub puab ib feem ntawm polyurethane elastomer thiab hloov mus rau hauv lub tshav kub zog. Yog li ntawd, polyurethane elastomers muaj qhov pom tseeb kev vibration absorption thiab tuaj yeem hu ua damping zog tib lub sijhawm.
7. Tsis tshua muaj kub tsis kam: Polyurethane elastomers muaj qhov kub zoo heev, qhov kub thiab txias yog feem ntau qis, thiab catalytic kub ntawm qee hom yog tsawg dua -70 degree, yog li cov khoom siv polyurethane elastomer tshwj xeeb tshaj yog tsim rau siv hauv qhov chaw txias;
8. Kev tiv thaiv hluav taws xob thiab tiv thaiv ozone: Ntawm cov ntaub ntawv polymer, polyurethane ntawm lub sijhawm siv tau zoo heev los tiv thaiv hluav taws xob thiab tiv thaiv ozone;
9. Anti-pwm kev ua tau zoo: Kev tiv thaiv pwm kev ua haujlwm ntawm polyether polyurethane yog qhov zoo, thiab qib yog 0-1, uas feem ntau tsis tuaj pwm;
10. Biomedical zog: Polyurethane cov ntaub ntawv muaj biocompatibility zoo heev. Kev kuaj mob toxicological mob thiab mob ntev thiab kuaj tsiaj tau ua pov thawj tias cov khoom siv kho mob polyurethane tsis muaj tshuaj lom, tsis muaj kev cuam tshuam, thiab tsis muaj kev phiv xws li kev tsis haum tshuaj.
Vim yog qhov zoo ntawm cov khoom saum toj no, cov ntaub ntawv polyurethane yog qhov zoo heev hauv kev lag luam cov hlua, uas tau txhim kho qee qhov kev ua tau zoo ntawm cov tshuab xa mus rau tag nrho, ua rau muaj txiaj ntsig zoo rau kev txhim kho kev lag luam.
