Horumarinta Dhumucda Rheological

Horumarinta dhumucyada rheological waxay ahayd taariikh muhiim ah taariikhda sayniska agabka iyo injineernimada. Dhumucyada Rheological waa maaddooyin kordhin kara viscosity iyo/ama xakamaynta sifooyinka socodka dareeraha, ganaaxyada, iyo emulsions.

Dhumucdii ugu horeysay ee rheological waxaa la helay si lama filaan ah qarnigii 19-aad, markii biyo iyo bur la isku daray ayaa loo daayay in ay istaagaan muddo, taas oo keentay in la helo dhumuc weyn, oo u eg jel. Isku dhafkan ayaa markii dambe la ogaaday inuu yahay hakin fudud oo ah qayb ka mid ah burka biyaha, kuwaas oo loo isticmaali karo dhumucyada codsiyada kala duwan.

Horraantii qarnigii 20aad, agabyo kale ayaa la ogaaday inay leeyihiin sifooyin dhumuc leh, sida istaarijka, cirridka, iyo dhoobada. Agabkaan waxa loo isticmaalay sidii dhumucyada rheological ee codsiyada kala duwan, laga bilaabo cuntada iyo waxyaalaha la isku qurxiyo ilaa rinji iyo dareerayaasha qodista.

Si kastaba ha ahaatee, dhumucyadan dabiiciga ah waxay lahaayeen xaddidaadyo, sida waxqabadka isbeddelka, dareenka xaaladaha habaynta, iyo wasakhowga microbiological ee suurtagalka ah. Tani waxay keentay horumarinta dhumucyada rheological synthetic, sida ethers cellulose, polymers acrylic, iyo polyurethane.

Ethers Cellulose, sida sodium carboxymethyl cellulose (CMC), methyl cellulose (MC), iyo hydroxypropyl cellulose (HPC), ayaa noqday mid ka mid ah dhumucyada rheological ugu isticmaalka badan ee codsiyada kala duwan, ay sabab u tahay sifooyinka gaarka ah, sida milanka biyaha. xasilloonida pH, dareenka xoogga ionic, iyo kartida samaynta filimada.

Horumarinta dhumucda rheological synthetic ayaa awood u leh samaynta alaabooyinka leh waxqabad joogto ah, hagaajinta xasilloonida, iyo shaqeynta la xoojiyay. Baahida sii kordheysa ee agabka waxqabadka sare leh, horumarinta dhumucyada rheological ee cusub ayaa la filayaa inay sii socoto, taasoo ay horseedayso horumarka laga gaaray sayniska, kimisteriga, iyo injineernimada.
