BG-2680-80P

Umuti wo gukiza amazi-BG-2680-80P

Ibisobanuro bigufi:

BG-2680-80P ni amazi akwirakwiza alifatique polyisocyanate yo gukiza ishingiye kuri hexamethylene diisocyanate. Ifite ibiranga nk'urumuri rwinshi, ubwuzure bwiza, ubukana bwinshi, imiti irwanya imiti, byoroshye gukurura intoki, n'ubuzima bw'inkono ndende.

Ibisubizo

Kuvangwa na propylene glycol methyl ether acetate (PMA), ifatanije na polyurethane ishingiye ku mazi, polyacrylate, nibindi, bikoreshwa mumirima yo gutwika ibiti biva mu mazi hamwe n’inganda.

Ibisobanuro

Ibirimo bidahindagurika (%)	78 ~ 82
Viscosity (mPa • s / 25 ℃)	500 ~ 80
Ubuntu HDI monomer (%)	≤0.1
Ibirimo NCO (gutanga%)	15.0 ~ 16.0

Amabwiriza

Iyo ukoresheje BG-2680-80P, umusemburo nka propylene glycol methyl ether acetate (PMA) na diacetate ya propylene glycol (PGDA) urashobora kongerwamo imbaraga. Birasabwa gukoresha ammonia ester yo mu rwego rwo hejuru (ifite amazi ari munsi ya 0,05%) kugirango uyungurure, hamwe nibintu bikomeye bitari munsi ya 40%. Kora ubushakashatsi bwihariye mbere yo gukoresha no kwipimisha. Uruvange rwongewemo na BG-2600-100 rugomba gukoreshwa mugihe cyo gukora.

ububiko

Ibicuruzwa bigomba kubikwa mu kintu gifunze kugirango wirinde ubukonje n'ubushyuhe bwinshi. Birasabwa kugumisha gupakira neza mubushyuhe bwa 5-35 ℃. Ubuzima bwibicuruzwa nibicuruzwa ni amezi cumi n'abiri uhereye igihe byatangiriye. Nyuma yubuzima bwikirenga burenze, birasabwa gukora isuzuma ryimikorere mbere yo gukoreshwa.

Ibicuruzwa byumva cyane ubushuhe kandi bifata amazi kugirango bitange imyuka nka karuboni ya dioxyde na urea, bishobora gutera umuvuduko wa kontineri kuzamuka kandi bigatera akaga. Nyuma yo gufungura ibipaki, birasabwa kubikoresha vuba bishoboka.
