Maanta, waxaan kaala hadli doonaa isticmaalka caadiga ah ee hydroxyethyl cellulose ee rinjiga iyo dahaarka.Rinjiga, oo dhaqan ahaan loogu yeero dahaarka Shiinaha.Dahaarka loogu yeero waxaa lagu daboolaa dusha sare ee shayga si loo ilaaliyo ama loo qurxiyo, wuxuuna samayn karaa filim joogto ah oo si adag ugu xiran shayga la daboolay.
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 etherification of cellulose alkaline iyo ethylene oxide (ama chlorohydrin), oo ka tirsan cirridka Nonionic ethers cellulose soluble.Sababtoo ah HEC waxay 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 iyo cuntada, dunta, waraaqaha iyo polymers.Polymerization iyo qaybaha kale.
Maxaa dhacaya marka hydroxyethyl cellulose la kulmo biyo ku salaysanrinji?
Sida surfactant-aan-ionic ah, hydroxyethyl cellulose waxay leedahay sifooyinka soo socda marka lagu daro dhumuc, laalitaan, xidhidh, sabbaynaya, filim samaynta, kala firdhinta, haynta biyaha iyo bixinta kolloid ilaalinta:
HEC waxay ku milmi kartaa biyo kulul ama qabow, oo kuma soo da'in heerkulka sare ama karkarinta, taasoo ka dhigaysa inay leedahay noocyo kala duwan oo ah milanka iyo sifooyinka viscosity, iyo sidoo kale gelling aan kulaylka ahayn;
Awoodda xajinta biyaha waa laba jeer ka 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 wakhtiga wax soo saarka - habkani waa kan ugu fudud oo qaata waqti yar.
Ku dar biyo nadiif ah makiinada lagu rakibay blender xiirid sare leh.Ku billow inaad si joogto ah u walaaqdo xawaare hooseeya oo si tartiib ah u shaandhee hydroxyethyl cellulose si siman xalka.Sii wad walaaq ilaa dhammaan qaybaha la qooyay.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 kordhiyaa) ka hor inta aan lagu darin qaybaha kale ee caanaha si loo fuliyo falcelinta.
Ku qalabaysan khamriga hooyada.
Waa in marka hore la diyaariyo khamriga hooyada oo leh feejignaan sare, ka dibna ku dar 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 ayaa ah in aysan jirin baahi loo qabo kicinta xiirid sare, oo kaliya qaar ka mid ah agitators oo leh awood ku filan si ay u ilaaliyaan cellulose hydroxyethyl si isku mid ah u kala firirsan xalka ayaa loo isticmaali karaa, oo sii wad walaaq ilaa si buuxda u milmo xal viscous ah.Si kastaba ha ahaatee, waa in la ogaadaa in wakiilka antifungal waa in lagu daro khamriga hooyada sida ugu dhakhsaha badan.
Maadaama dusha sare ee hydroxyethyl cellulose lagu daaweeyay ay tahay budo ama adag, Shandong Heda waxay ku xasuusineysaa inaad fiiro gaar ah u yeelato qodobada soo socda markaad diyaarineyso khamriga hooyada hydroxyethyl cellulose:
(1) Kahor iyo ka dib marka lagu daro hydroxyethyl cellulose, waa in lagu hayaa walaaq ilaa inta xalku si buuxda u hufan yahay oo cad yahay.
(2) Waa in si tartiib ah loogu miiraa foostada isku dhafka ah, oo aan si toos ah ugu xidhin hydroxyethyl cellulose iyo hydroxyethyl cellulose gudaha foostada isku dhafka ah oo tiro badan ama qaab buro iyo kubbado ah.
(3) Heerkulka biyaha iyo qiimaha pH ee biyuhu waxay leeyihiin xidhiidh cad oo la xidhiidha milanka hydroxyethyl cellulose, markaa waa in fiiro gaar ah la siiyaa.
(4) Waligaa walxo alkaline ah ha ku darin isku darka ka hor inta aan budada hydroxyethyl cellulose lagu qooyay biyo.Kor u qaadista pH kaliya ka dib qoynta waxay kaa caawin doontaa in la milmo.
(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 adag tahay in la xakameeyo.
