Khoom piav qhia

NDI polyurethane elastomer yog ib hom polyurethane (PU), rigidity, symmetry, thiab tsis tu ncua ntawm NDI yog siab dua lwm cov isocyanates, xws li MDI, TDI, IPDI. Li no, nws muaj peev xwm radically txhim kho theem sib cais degree ntawm mos thiab tawv polyurethane ntu, yog li muab NDI polyurethane zoo heev physicochemical zog.

Cov khoom ntawm NDI yog qhov zoo tshaj plaws kev co conroll, tsis kam, abradable sealing cov khoom uas muaj qhov zoo ntawm kev puas siab puas ntsws tsis kam, siab kub tsis kam, siab zog, roj resistant corrosion, me me sab hauv tshav kub, zoo dynamic khoom thiab zoo heev resilience.

NDI polyurethane elastomer tuaj yeem siv rau hauv ib puag ncig tshwj xeeb uas cov roj hmab ib txwm siv lossis polyurethane zoo tib yam tsis tuaj yeem ua tau raws li qhov xav tau lossis ua rau muaj kev puas tsuaj ntxov.

NDI (naphthalene diisocyanate) yog ib yam tshiab ntawm polyurethane raw khoom nrog siab reactivity thiab zoo heev tshav kub tsis kam.Polyurethane ua los ntawm NDI muaj zoo heev zog, hardness thiab hnav tsis kam, thiab yog haum rau ua high-zoo polyurethane khoom, xws li engineering yas thiab tshwj xeeb elastomers.Txawm li cas los xij, NDI kuj muaj qee qhov tsis zoo hauv kev tsim khoom thiab siv cov txheej txheem, xws li cov nqi ntau lawm thiab yooj yim crystallization.

Kev ua tau zoo sib txawv: Polyurethane ua los ntawm NDI muaj lub zog zoo heev, hardness thiab hnav tsis kam, thiab yog tsim rau kev ua haujlwm siab polyurethane cov khoom, xws li engineering plastics thiab tshwj xeeb elastomers.Piv nrog TDI thiab MDI, polyurethane ua los ntawm NDI muaj kev kub siab dua thiab zoo dua dimension stability.

Polycaprolactone yog ib chav kawm tshwj xeeb ntawm kev ua haujlwm siab ntawm polyester polyols.Los ntawm cov qauv tshuaj ntawm qhov pom, polycaprolactone polyols yog hexane glycol adipate.Cov txheej txheem uas polycaprolactone polyols yog tsim los piv rau cov qauv glycol adipate txiav txim siab lawv lub cev muaj zog.Polycaprolactone polyols yog tsim los ntawm lub nplhaib qhib ntawm lub nplhaib heterocyclic (caprolactone monomer) los ntawm glycol pib.Qhov ntawm cov tshuaj tiv thaiv no ua rau muaj qhov tsis tshua muaj polydispersity (qis molecular hnyav faib).Qhov tsis muaj qhov hnyav molecular hnyav pom hauv cov qauv polyester polyols ua rau qis dua. viscosities pom nyob rau hauv polycaprolactone polyols.Tsis tas li ntawd, qhov tsis muaj qhov tsis muaj qhov hnyav molecular tus Tsov tus tw ua rau muaj kev ua tau zoo qis thiab kub siab. Tsis tas li ntawd, polycaprolactone polyols nthuav tawm txhim kho hydrolytic stability piv rau tus qauv glycol adipates vim lawv tau ua nyob rau hauv me me thiab tsis muaj acid catalysis.

BQ4650 yog siv rau Polycaprolactone thiab NDI system Polyurethane Elastomer.

BQ4650 suav nrog A thiab B Cheebtsam.A tivthaiv yog tus neeg sawv cev kho; B tivthaiv yog Polycaprolactone thiab NDI pre-polymer.

yam ntxwv:

Mechanical excellence: Siab tensile lub zog thiab tsim kua muag kuj, tsis tshua muaj compression teeb thiab puas poob.

Dynamic excellence: Tsawg zog poob thiab kub build-up, siab rebound resilience.

Unique microcellular qauv: Sib txuas cov ntim siab compressibility nrog tsawg transverse expansion.

Thaum tshav kub kub-resistant: Kev ua haujlwm tsis tu ncua mus txog 80 degree, rau lub sijhawm luv txog li 120 degree.

Media-resistant: Zoo tiv thaiv UV hluav taws xob, ozone, roj, thiab roj.

Cia

Khaws rau hauv qhov chaw txias thiab qhuav thiab siv kom sai li sai tau tom qab qhib;

Nws yuav tsum tau muab ntim nrog nitrogen yog tias nws tsis tuaj yeem siv ib zaug;

Thawj lub sij hawm cia yog rau lub hlis.
