Sidee loogu daraa Hydroxyethyl Cellulose Dahaarka?

Hydroxyethyl cellulose (HEC) waa dhumuc caadi ah iyo wax ka beddelka rheology kaas oo loo isticmaalo qaabab kala duwan oo daahan ah, oo ay ku jiraan rinji, dhejisyo, iyo daboolayaal.Markaad ku darto HEC dahaarka, waa muhiim inaad raacdo dhowr tillaabo oo muhiim ah si loo hubiyo in si sax ah loo firdhiyey oo fuuq baxay.Waa kuwan tillaabooyinka guud ee lagu daro HEC ee daaha:

1. Diyaari fidinta HEC HEC waxaa sida caadiga ah loo bixiyaa sida budo qalalan oo ay tahay in lagu firdhiyo biyaha ka hor inta aan lagu darin daboolka.Si aad u diyaariso kala firdhinta HEC, ku dar qiyaasta la rabo ee budada HEC biyaha adigoo si joogto ah u walaaqaya.Xoojinta lagu taliyey ee HEC ee kala firidhsan waxay ku xiran tahay codsiga gaarka ah iyo viscosity la doonayo ee daahan.
2. Isku qas kala firdhinta HEC ee dahaarka Marka fidinta HEC si buuxda u fuuqbaxdo iyo qaybaha HEC si buuxda ayaa loo kala firdhiyey, si tartiib ah ugu dar daahan adigoo si joogto ah u qasaya.Waa muhiim in si tartiib tartiib ah loogu daro kala firdhinta HEC si looga hortago isku-duubnaanta iyo in la hubiyo in si siman loo qaybiyo dhammaan dahaarka.Xawaaraha isku dhafka waa in lagu hayaa heer dhexdhexaad ah si looga hortago xad-dhaafka hawada.
3. Hagaajin pH ee daahan HEC waxay u nugul tahay pH waxayna si fiican ugu shaqeysaa qiyaasta pH ee 6-8.Sidaa darteed, waxaa muhiim ah in la hagaajiyo pH ee daahan ilaa xadkan ka hor inta aan lagu darin faafinta HEC.Tan waxaa lagu samayn karaa iyada oo lagu daro qadar yar oo ah wakiilka hagaajinta pH, sida ammonia ama sodium hydroxide, daahan iyadoo la kormeerayo pH-ga.
4. U oggolow dahaarka inuu nasto oo qaan gaaro Ka dib marka lagu daro kala firdhinta HEC ee daahan, waxaa lagu talinayaa in la oggolaado isku dar ah in ay nasato ugu yaraan 30 daqiiqo si loogu oggolaado HEC in ay si buuxda u fuuqbaxdo oo ay dhumucdo daboolka.Waa muhiim in la walaaqo isku dhafka xilliyadan inta lagu jiro waqtigan si looga hortago dejinta iyo in la hubiyo in HEC si siman loo qaybiyo.Dahaarka waa in sidoo kale loo oggolaadaa inuu qaan-gaaro ugu yaraan 24 saacadood ka hor inta aan la isticmaalin si loo hubiyo in HEC ay si buuxda u xoojisay daahan.

Guud ahaan, ku darista HEC ee dahaarka waxay ku lug leedahay diyaarinta kala firdhinta HEC, si tartiib ah ugu darista daahan iyadoo si joogto ah isku dhafan, hagaajinta pH ee daahan, iyo u oggolaanshaha isku dar ah inuu nasto oo qaan gaaro ka hor isticmaalka.Tallaabooyinkan soo socda waxay kaa caawin karaan inaad hubiso in HEC ay si buuxda u kala firdhisay oo fuuqbaxday, taasoo keentay dahaarka si fiican u dhumucdiisuna leh sifooyinka rheological ee la doonayo.
