Cov yam ntxwv thiab kev siv
E-90 yog ib qho viscosity aliphatic theem nrab diamine chain extender. Nws cov pab pawg reactive yog ib tug me ntsis tsis tshua muaj zog theem nrab amino pawg, uas ua rau cov saw extender muaj ib tug haum cov tshuaj tiv thaiv ceev thiab yooj yim dua rau kev khiav lag luam. Nws tuaj yeem siv ib leeg lossis sib xyaw nrog lwm cov amine / cawv saw txuas ntxiv los npaj cov tshuaj tsw qab / aliphatic polyurethane urea thiab polyurea khoom, xws li RIM polyurethane, cam khwb cia polyurethane elastomer, polyurethane sealing cov ntaub ntawv, coatings, adhesives, Spray polyurethane urea, thiab lwm yam. npaj raws li E-90 thiab aliphatic diisocyanate muaj huab cua zoo heev.

Pob
200kg galvanized nruas, lossis ntim tshwj xeeb raws li cov neeg siv khoom xav tau.
Txuag
Khaws ntim rau hauv qhov chaw txias, qhuav. Cov xim yuav tsaus dua yog tias khaws cia ntev dhau los lossis nyob rau hauv qhov chaw teeb pom kev zoo, uas feem ntau tsis cuam tshuam rau qhov reactivity.
Lub neej txee yog 2 xyoos. Yog tias qhov chaw khaws cia tshaj lub txee lub neej, nws tseem tuaj yeem siv tau tom qab dhau qhov kev tshuaj ntsuam xyuas ntawm cov ntawv thov tseem ceeb.
