Hordhac

Diphenylmethane-4,4'-diisocyanate, sidoo kale loo yaqaan MDI. Waa iskudhis organic ah waana nooc ka mid ah xeryahooda benzodiisocyanate.

 

Tayada:

1. Muuqashada: MDI waa mid aan midab lahayn ama huruud khafiif ah.

2. Solubility: MDI waxa ay ku milmaysaa dareerayaasha organic sida chlorinated hydrocarbons iyo hydrocarbons caraf udgoon.

 

Isticmaal:

Waxaa loo isticmaalaa sida walxo ceeriin ah oo loogu talagalay xeryahooda polyurethane. Waxay la falcelin kartaa polyeter ama polyols polyurethane si ay u sameeyaan elastomer poliurethane ama polymers. Qalabkani wuxuu leeyahay codsiyo badan oo kala duwan oo ku saabsan dhismaha, baabuurta, alaabta guriga, iyo kabaha, iyo kuwo kale.

 

Habka:

Habka diphenylmethane-4,4'-diisocyanate inta badan waa in uu ka falceliyo aniline leh isocyanate si loo helo isocyanate ku salaysan aniline, ka dibna loo maro falcelinta diazotization iyo denitrification si loo helo badeecada la beegsanayo.

 

Macluumaadka Badbaadada:

1. Ka fogow taabashada: Ka fogow taabashada maqaarka oo toos ah oo lagu rakibo qalab ilaalin shaqsiyeed oo habboon sida galoofyada, muraayadaha iyo dharka ilaalinta.

2. Hawo-qaadis: Ilaali xaaladaha hawo-siineed ee wanaagsan inta lagu jiro hawlgalka.

3. Kaydinta: Marka la kaydinayo, waa in la xidhaa lagana fogeeyaa ilaha dabka, meelaha kulaylka iyo meelaha ay ka dhacaan ilaha dabka.

4. Qashinka daadinta: Qashinka waa in si fiican loo daaweeyaa oo la tuuraa, oo aan la daadin sida la doono.

Marka la maaraynayo walxaha kiimikaad, waa in loo maareeyaa si adag oo waafaqsan nidaamka hawlgalka shaybaadhka iyo hab-raaca badbaadada, iyo si waafaqsan shuruucda iyo xeerarka khuseeya.
