Rinjiga, oo dhaqan ahaan loogu yeero rinjiga Shiinaha.Rinjiga waxa loogu yeero waxaa lagu dahaadhay dusha shayga si loo ilaaliyo ama loo qurxiyo, wuxuuna samayn karaa filim joogto ah oo si adag ugu xiran shayga la dahaadhay.
Waa maxay Hydroxyethyl Cellulose?
Hydroxyethyl cellulose (HEC), jaale cad ama iftiin ah, aan ur lahayn, fibros aan sun ahayn ama adag budo ah, oo lagu diyaariyey falcelinta etherification ee cellulose alkaline iyo ethylene oxide (ama chlorohydrin), waxaa iska leh ethers cellulose ee Nonionic milmaya.Maaddaama HEC ay leedahay sifooyin wanaagsan oo dhumucdiisuna waxay tahay, hakin, kala firdhiyo, emulsifying, bonding, film-samaynta, ilaalinta qoyaanka iyo bixinta kolloid ilaalinta, waxa si weyn loogu isticmaalay sahaminta saliidda, dahaarka, dhismaha, daawada, cuntada, dunta, waraaqaha iyo polymer polymerization. iyo goobo kale.
Maxaa dhacaya marka hydroxyethyl cellulose ay la kulmaan rinjiga biyaha ku salaysan?
Sida surfactant-ka aan-ionic ahayn, hydroxyethyl cellulose waxay leedahay sifooyinka soo socda marka lagu daro dhumuc, laalitaan, xidhidh, sabbayn, filim samaynta, kala firdhisan, haynta biyaha iyo bixinta kolloid ilaalin ah:
HEC waxay ku milmi kartaa biyo kulul ama biyo qabow, heerkul sare ama karkaraya iyada oo aan roob lahayn, si ay u leedahay noocyo kala duwan oo ah milanka iyo sifooyinka viscosity, iyo gelation non-thermal;
Awoodda haynta biyuhu waxay laban laab ka badan tahay tan methyl cellulose, waxayna leedahay nidaaminta qulqulka wanaagsan;
Marka la barbar dhigo methyl cellulose-ka la aqoonsan yahay iyo hydroxypropyl methyl cellulose, awoodda kala firdhisan ee HEC waa tan ugu xun, laakiin awoodda kolloid ilaalinta ayaa ah tan ugu xooggan.
Waa non-ionic oo waxay la noolaan kartaa tiro balaadhan oo ah polymers kale oo biyo-milmi kara, surfactants, iyo cusbo.Waa dhumuc weyn oo kolloidal ah oo loogu talagalay xalalka korantada ee xoogga leh;
Sida loo isticmaalo hydroxyethyl cellulose?Sidee loogu dari karaa?
Ku dar si toos ah inta lagu jiro wax soo saarka - habkani waa kan ugu fudud oo qaata wakhtiga ugu gaaban.
Ku dar biyo nadiif ah baaldi weyn oo ku qalabaysan qasiyaha xiirid sare.Bilow inaad si joogto ah u walaaq xawaare hoose oo si tartiib ah u kala miir hydroxyethyl cellulose si siman xalka.Sii wad walaaq ilaa dhammaan qaybaha ay qooyaan.Ka dibna ku dar maadada-ilaalinta iyo waxyaallaha kala duwan.Sida midabada, qalabka kala firdhisan, biyaha ammonia, iwm. Walaaq ilaa dhammaan cellulose hydroxyethyl ay si buuxda u milmaan (viskosity ee xalku si weyn ayuu u korayaa) ka hor intaadan ku darin qaybaha kale ee qaacidada falcelinta.
Ku qalabaysan khamriga hooyada
Waa in marka hore la diyaariyo khamriga hooyada oo leh feejignaan sare, ka dibna lagu daro alaabta.Faa'iidada habkani waa in uu leeyahay dabacsanaan weyn oo si toos ah loogu dari karo alaabta la dhammeeyey, laakiin waa in si habboon loo kaydiyaa.Tallaabooyinka habkani waxay la mid yihiin inta badan tillaabooyinka habka 1;Farqiga u dhexeeya ayaa ah in aysan jirin baahi loo qabo kicinta xiirid sare leh, oo kaliya qaar ka mid ah agitators oo leh awood ku filan si ay u ilaaliyaan cellulose hydroxyethyl si isku mid ah u kala firdhisanaanta xalka ayaa la sii wadi karaa iyada oo aan la joojin Walaaq ilaa si buuxda loo kala diro xal viscous ah.Si kastaba ha ahaatee, waa in la ogaadaa in fungicides waa in lagu daraa khamriga hooyada sida ugu dhakhsaha badan.
Maadaama dusha lagu daaweeyay hydroxyethyl cellulose ay tahay budo ama adag, Lihongde waxay ku xasuusinaysaa inaad fiiro gaar ah u yeelato qodobada soo socda markaad diyaarinayso khamriga hooyada hydroxyethyl cellulose:
(1) Kahor iyo ka dib marka lagu daro hydroxyethyl cellulose, waa in si joogto ah loo walaaqaa ilaa xalku si buuxda u hufan yahay oo cad yahay.
(2) Waa in si tartiib ah loogu miiraa taangiga isku-darka ah, oo ha saarin xaddi badan ama si toos ah ha u gelin hydroxyethyl cellulose haanta isku-darka ah.
(3) Heerkulka biyaha iyo qiimaha PH ee biyaha ayaa xiriir weyn la leh kala dirida cellulose hydroxyethyl, markaa waa in fiiro gaar ah la bixiyaa.
(4) Ha ku darin qaar ka mid ah walxaha alkaline isku dhafka ka hor inta aan budada hydroxyethyl cellulose lagu qooyay biyo.Kor u qaadista pH ka dib qoynta waxay caawisaa inay milmaan.
(5) Inta suurtogalka ah, horay ugu sii daa wakiilka antifungal
(6) Marka la isticmaalayo hydroxyethyl cellulose-viscosity-sare, fiirsashada khamriga hooyadu waa inuusan ka badnaan 2.5-3% (miisaan ahaan), haddii kale khamriga hooyadu way adkaan doontaa in la xakameeyo.
