Amazi yo Kuvura Amazi-BG-2655-100 Ishusho Yerekanwe
  • Umuti wo gukiza amazi-BG-2655-100

BG-2655-100

Umuti wo gukiza amazi-BG-2655-100

Ibisobanuro bigufi:

BG-2655-100 ni imiti ikwirakwiza amazi ya isocyanate ikiza ishingiye kuri hexamethylene diisocyanate ， ikoreshwa ifatanije na polyurethane yo mu mazi, polyacrylate, hamwe na hydrolysis nziza kandi irwanya ubushyuhe.

Amazi yateguwe ashingiye kubice bibiri bigize ibice bifite ibiranga urumuri rwinshi, ubwuzure bwinshi, ubukana bwinshi, kurwanya umuhondo mwiza, hamwe no kurwanya imiti myiza.

Amabwiriza

Iyo BG-2655-100 itatanye, ububobere bwayo buziyongera. Iyo ivanze na hydrophilique polyol ikwirakwizwa, irashobora kuvangwa n'amazi hakiri kare cyangwa umubare muto wa solvent urashobora kongerwamo kugirango igabanye kwiyongera kwijimye, nka propylene glycol methyl ether acetate (PMA), diacetate ya propylene glycol (PGDA), kandi nayo birasabwa gukoresha polyurethane yo mu rwego rwo hejuru (ibirimo amazi <0,05%) kugirango bigabanuke, hamwe nibintu bikomeye bitari munsi ya 40%. Kora ubushakashatsi bwihariye nibizamini bihamye mbere yo gukoresha. Niba imvange nyuma yo kongeramo BG-2655-100, igomba gukoreshwa imbereubuzima bw'inkono.

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.
