Bayhydur XP2547 Lwm Txoj Kev HDI HEEV

Cov cim bayhydur 2547 yog hydrohatic aliphatic polyisocyanate raws li Hexamethylene Diisocyanate (HDI).

Nws yog qhov haum uas yog ib qho nyuaj rau cov dej pheebsuab ob lub tsho sib ntxiv, cov tsho tshaj sab saum toj, cov khoom sib dhos thiab ua ib qho ntxiv los txhim kho cov cuab yeej profile.

Cov cuab yeej khoom ntiag tug ntawm txoj kev ntsuas ntsuas

Hazen xim tus nqi: tsawg dua los yog sib npaug rau 150

Viscosity ntawm 23 degree570 - 730 mpa ∙ s

NCO NTSIAB LUS: 22 - 23%

Monomeric HDI: <0.5%

Solubility / thannability

Cov khoom lag luam feem ntau tau tshaj tawm nrog cov kuab tshuaj muaj cov organic xws li esters lossis kev ua kom zoo. Txawm li cas los xij, solubility thiab sib xyaw yuav tsum tau kuaj nyob rau hauv txhua kis. Hais txog cov tshuaj tiv thaiv ntawm cov kuab tshuaj (cosvent) ntawm lub emulsibility ntawm polyisocyanate, thov saib cov ntaub ntawv hauv seem "cov khoom / cov ntawv thov". Tsuas yog siv cov tshuaj-pu yuav tsum tau siv (< 0.05% water).

Vim tias nws hydrophilic tus cwj pwm, bayhydur 2547 tuaj yeem yooj yim tawg hauv theem aqueous. Nws yog siv feem ntau ua tus neeg sawv cev hla rau cov ntug dej polyol Binders (Bayhydol®). Qhov kev tawm tsam ntawm cov khoom hauv dej yog cuam tshuam los ntawm cov tshuaj pleev cov orgolic. Kev siv ntawm hydrophilic cosvents xws li butyl acetate, xyooj, tab sis n-methyl lug ua si Ntawm qhov tod tes, kev siv ntawm, piv txwv li, methhothenge ethylkastate glycole glycolic acid diester mixtures ua rau kev sib cais zoo.

BAYHYDUR 2547 kuj tseem tuaj yeem muab ntxiv rau cov pah-dawb tawg los txhim kho lawv cov cuab yeej profiles.

Raws li nrog cov khoom lag luam, siv Bayhydur 2547 hauv daim ntawv thov yuav tsum raug kuaj (suav nrog tab sis tsis txwv los ntawm tus neeg siv los txiav txim siab
