Dab tsi yog cov yam ntxwv ntawm cam khwb cia polyurethane elastomers?
1. Cov yam ntxwv muaj ntau yam adjustable.
Ntau qhov ntsuas lub cev thiab cov cuab yeej cuab yeej cuab tam tuaj yeem hloov pauv hauv cov cheeb tsam sib xws raws li kev xaiv cov khoom siv raw thiab kev hloov kho ntawm cov qauv, yog li ua tau raws li cov neeg siv khoom sib txawv ntawm cov khoom siv. Piv txwv li, hardness feem ntau yog qhov ntsuas tseem ceeb rau cov neeg siv los xav txog cov khoom. Polyurethane elastomers tuaj yeem ua rau cov tshuab luam ntawv muag muag nrog Shore A hardness txog li 20, los yog tawv steel dov rollers nrog Shore D hardness ntau dua 70., uas nyuaj rau kev ua tiav nrog cov khoom siv elastomer zoo tib yam. Polyurethane elastomer yog cov khoom siv polar polymer uas muaj ntau qhov hloov tau yooj yim thiab ntu ntu. Raws li qhov kev faib ua feem ntawm ntu ntu nce thiab qhov ceev ntawm pawg polar nce, qhov qub zog thiab hardness ntawm elastomer yuav nce raws li.
2. Kev hnav zoo heev
Tshwj xeeb tshaj yog nyob rau hauv kev ua hauj lwm tej yam kev mob nyob rau hauv lub xub ntiag ntawm dej, roj thiab lwm yam humid media, nws hnav tsis kam yog feem ntau ob peb mus rau kaum ob lub sij hawm ntawm cov khoom siv roj hmab zoo tib yam. Txawm hais tias cov khoom siv hlau xws li steel yog qhov nyuaj heev, lawv tsis tas yuav hnav-tiv taus. Piv txwv li, nyob rau hauv cov twj tso kua dej loj hauv cheeb tsam Yellow River irrigation, cov hlau orifice rings thiab tiv thaiv rings ntawm cov ntws-dav qhov chaw tau raug ntxuav tawm los ntawm ib tug loj npaum li cas ntawm sediment, thiab lawv yuav ua hnyav hnyav thiab leaky nyob rau hauv ob peb. puas teev. , thiab lub nplhaib lub qhov ncauj thiab lub nplhaib tiv thaiv (cyclone) npog nrog polyurethane elastomer tau txuas ntxiv ua haujlwm rau 1800 teev yam tsis hnav. Lwm yam muaj xws li roj hmab rollers rau mov hullers, vibrating npo daim hlau rau cov ntxhia ua, khiav thiab teb lem rau kev ua si teb, dynamic roj sealing rings rau cranes thiab forklifts, elevator log thiab skate log, polyurethane khoom log tsheb, luam ntawv thiab silk Screen printing squeegees kuj siv rau polyurethane elastomers. Ib yam uas yuav tsum tau hais txog ntawm no yog txhawm rau ua kom muaj kev sib txhuam coefficient ntawm nruab nrab thiab qis hardness polyurethane elastomer qhov chaw thiab txhim kho qhov hnav tsis kam nyob rau hauv kev thauj khoom, ib qho me me ntawm aluminium disulfide, graphite lossis silicone roj tuaj yeem ntxiv rau hom polyurethane. elastomer. Lubricant.
3. Ntau yam kev tsim khoom thiab kev ua haujlwm, kev siv dav dav
Castable polyurethane elastomer tuaj yeem ua pwm siv tib yam mastication, sib tov, thiab vulcanization txheej txheem raws li feem ntau siv roj hmab (hu ua MPU); nws tseem tuaj yeem ua rau cov roj hmab ua kua, cam khwb cia thiab molded lossis txau, potted, thiab centrifugally molded (hu ua CPU); los yog nws tuaj yeem ua kua roj hmab. Nws tuaj yeem ua rau pellets thiab molded los ntawm kev txhaj tshuaj, extrusion, calendering, tshuab moulding thiab lwm yam txheej txheem xws li cov yas yas (hu ua TPU). Moulded lossis txhaj tshuaj molded qhov chaw kuj tseem tuaj yeem ua tiav los ntawm kev txiav, sib tsoo, drilling thiab lwm yam kev ua haujlwm hauv thaj chaw hardness. Kev sib txawv ntawm kev tsim khoom thiab kev ua haujlwm ua rau polyurethane elastomers muaj ntau yam thiab nws daim ntawv thov teb txuas ntxiv nthuav dav.4. Roj tsis kam, ozone kuj, kev laus tsis kam, hluav taws xob tsis kam, tsis kub tsis kam, zoo suab kis tau tus mob, muaj zog adhesion, biocompatibility zoo heev thiab ntshav compatibility yog cov yam ntxwv ntawm polyurethane elastomers hauv kev lag luam tub rog, aerospace, acoustics, thiab lwm yam. Yog vim li cas nws tau dav siv nyob rau hauv cov teb xws li biology.
