Hordhac

Glutaraldehyde, oo sidoo kale loo yaqaan valerdehyde. Kuwa soo socdaa waa horudhac ku saabsan sifooyinka, isticmaalka, hababka diyaarinta iyo macluumaadka badbaadada glutaraldehyde:

 

Tayada:

Glutaraldehyde waa dareere aan midab lahayn oo leh ur daran. Waxay la falgashaa hawo iyo iftiin waana isbedel. Glutaraldehyde wax yar bay ku milmi kartaa biyaha laakiin waxay ku milmaysaa inta badan dareerayaasha dabiiciga ah.

 

Isticmaal:

Glutaraldehyde waxay leedahay adeegsiyaal kala duwan. Waxa loo isticmaali karaa sidii dhexdhexaad kiimikaad ah ee warshadaha si loo soo saaro kiimikooyin kala duwan. Tusaale ahaan, waxaa loo isticmaali karaa isku-darka sunta cayayaanka, dhadhanka, xakamaynta koritaanka dhirta, iwm.

 

Habka:

Glutaraldehyde waxaa lagu heli karaa oksaydheynta acid-catalyzed ee pentose ama xylose. Habka diyaarinta gaarka ah waxaa ka mid ah falcelinta pentose ama xylose leh asiidh, iyo helitaanka alaabada glutaraldehyde ka dib oksaydhka, yaraynta iyo daaweynta fuuqbaxa.

 

Macluumaadka Badbaadada:

Glutaraldehyde waa kiimiko cuncun leh waana in laga fogaadaa taabashada tooska ah ee maqaarka iyo indhaha. Markaad la tacaalayso glutaraldehyde, galoofyada ilaalinta iyo muraayadaha indhaha waa in la xidhaa si loo hubiyo hawo wanaagsan. Waa in laga fogaadaa dabka iyo ilaha kulaylka, maadaama glutaraldehyde ay kacsan tahay oo ay jirto khatar gubasho. Inta lagu jiro isticmaalka iyo kaydinta, waa in la raaco hababka hawlgalka ee badbaadada si loo xaqiijiyo badbaadada loogana hortago shilalka.
