Cov yam ntxwv thiab kev siv
401 yog ib qho tshuaj tsw qab imine-hom latent curing tus neeg sawv cev ua los ntawm cov tshuaj tsw qab diamines thiab ketone-aldehyde compounds. Nws yog cov kua viscosity tsawg nyob rau hauv chav tsev kub thiab muaj kev sib raug zoo nrog NCO-based polyurethane prepolymers. Thiab tuaj yeem txo qhov viscosity ntawm chav tsev kub kho polyurethane systems.
401 decomposes sai sai thaum raug ya raws, thiab cov amino pawg reactive heev generated sai sai react nrog cov isocyanate pawg kom solidify, tawm hauv cov dej noo tsis muaj sij hawm los teb rau cov pawg isocyanate. Qhov no tiv thaiv kev tsim ntawm qhov pores vim qhov loj ntawm cov pa roj carbon dioxide tsis muaj sijhawm los khiav hauv cov nplaum nplaum.
401 feem ntau yog pom zoo rau siv nyob rau hauv ib tug-tivthaiv ya raws-kho polyurethane txheej tshuab, uas yuav daws tau qhov teeb meem foaming ntawm polyurethane systems thaum lub sij hawm ya raws. Nws tuaj yeem siv tau rau hauv chav tsev kub lossis nruab nrab-kub hnyav hnyav-dawb ob lub ntsiab lus polyurethane thiab lwm yam khoom. Kev siv tseem ceeb muaj xws li: polyurethane waterproof coatings, anti-corrosion coatings, floor coatings, thiab solvent-free polyurethane adhesives.
401 latent curing agent khoom yog cov khoom lag luam zoo ib puag ncig. Nws tsis tsim cov ntxhiab tsw phem thaum tsim khoom thiab tsim kho, muaj VOC emissions tsawg, thiab muab cov khoom siv kho polyurethane zoo txhua yam khoom.
Nws raug nquahu kom ua qhov kev sim me me ua ntej txhawm rau txiav txim siab qhov tsim nyog npaum li cas thiab kev ruaj ntseg cia hauv ib qho khoom siv polyurethane.

25kg yas nruas lossis 200kg hlau nruas uas tsis tuaj yeem siv dua.
Txuag
Cov khoom no yog rhiab heev rau dej thiab yuav decompose sai heev thaum raug dej (dej). Nws yuav tsum tau muab cia rau hauv qhov chaw kaw, qhuav, zoo-ventilated, thiab qhov chaw tsaus.
Thov khaws cov khoom siv tsis siv rau hauv lub thawv ntim khoom ntim nrog nitrogen kom tsis txhob muaj cov khoom ntub.
Lub neej txee yog 6 lub hlis. Yog tias lub kaw lus kaw tau dhau lub txee lub neej raws li qhov xav tau, nws tseem tuaj yeem siv tau tom qab dhau qhov kev tshuaj xyuas ntawm cov ntawv thov tseem ceeb.
