Bydroxyetylyll (HEC)Waa unug-biyo-biyo-miyir-biyood-biyoodka, oo si weyn loogu isticmaalo jaakadaha, qalabka dhismaha, dawada, kiimikooyinka maalinlaha ah iyo meelaha kale. Si kastaba ha noqotee, HEC waxay leedahay culeys biyo sare iyo biyo-daran oo daciif ah, oo u horseedi karta xadidaadaha waxqabadka ee xaaladaha codsiyada qaarkood. Sidaa darteed, hydrophopoxytylyluxyl byroxylyl (HMHEC) wuxuu galay inuu hagaajiyo guryaha rheolologiology, awoodda qaro weyn, xasilloonida emulsition iyo iska caabbinta biyaha.
1. Muhiimadda Hydrophobic wax ka badalida hydroxytyl cell
Hagaajinta guryaha qarogalinta iyo guryaha rheolologiolojiyada
Wax ka badalida hydrophobic si weyn ayey u hagaajin kartaa awoodda qarosiinta ee HEC, gaar ahaan heerarka xiida yar. Waxay muujineysaa muuqaal sare, kaas oo ka caawiya hagaajinta Thidotropy iyo Pseudoplasticlatity nidaamka. Hantidan ayaa si gaar ah muhiim ugu ah dhinacyada jaakadaha, cabitaannada saliida ee saliida, alaabada daryeelka shakhsi ahaaneed, iwm.
Hagaajinta xasilloonida emulsion
Maaddaama HEC-da wax la beddelay ay wax ka beddeli karto qaab is-afgaran oo ku jira xalka aqueous, waxay si weyn u wanaajisaa xasilloonida emulsion, waxay yareyn kartaa kala goynta biyaha-saliida, iyo hagaajinta saameynta emulsition. Sidaa darteed, waxay leedahay qiime codsi weyn oo ku saabsan qaybaha jaakadaha emulsion, alaabada daryeelka maqaarka iyo cunnada emulsifiers.
Kor u qaadista iska caabinta biyaha iyo astaamaha sameynta filimka
HEC dhaqameedku waa mid si heer sare ah oo si fudud loogu milmiyaa bey'adda sare ee huurka ama biyaha, taas oo saameeya caabbinta biyaha ee maaddada. Iyada oo loo marayo wax ka badalida hydrophopobic, codsigiisa ku jira jaakadaha, caqabadaha, is-beddelka iyo meelaha kale ee la xoojin karo, iyo astaamaha biyuhu u caabbinta biyuhu waa la hagaajin karaa.
Hagaajinta guryaha khafiifka ah ee galka
Hydrophobic-wax laga beddelay ayaa yareyn kara viscosity Shuruudaha xiirashada sare, iyadoo la ilaalinayo si joogto ah sicirka xijaabka yar, taasoo ka wanaajisa waxqabadka dhismaha iyo yareynta tamarta. Waxay leedahay qiimo muhiim ah ee warshadaha sida macdanta saliida ee saliida iyo jajabka qaab dhismeedka.
2. Wax ka badalida hydrophobic ee hydroxyetyl cellulose
Wax ka badalida HEC-da ee HEC Hydrophobic waxaa badanaa lagu gaaraa iyadoo la soo bandhigo kooxaha dareeraha ah si loo habeeyo xalideeda iyo qarogashadiisa sifooyinkiisa iyada oo loo marayo girting kiimikada ama wax ka badalida jirka. Qaababka wax ka beddelka ee caadiga ah ee wax ka beddelka ayaa ah sida soo socota:
Gradddrophobic Grafting
Soo bandhigida alkyl (sida hexadyyl), arxanyl (sida phenyl), sida phenyl), sidoon ah), Sidoon (Sidoon), sidoon ama kooxo lagu dhajiyay oo ku yaal molilaule-ka HEC ee loo maro fal-celinta kiimikada si loo wanaajiyo hawo-qaadashada kiimikada. Tusaale ahaan:
U adeegsiga ehelka ama falcelinta la soo saaray ee silsiladda muddada dheer-alkyl ee muddada dheer, sida hexadecyl ama octy, si loo sameeyo qaab-dhismeedka la-hawlgalayaasha hydrophobic.
Soo bandhigida kooxaha silicone iyada oo loo marayo wax ka badalida Silicone ah si loo hagaajiyo caabbigooda biyuhu iyo saliidu.
Isticmaalidda wax ka badalista falcelinta si loo wanaajiyo caabbinta cimilada iyo hydrophobicity, taasoo ka dhigeysa mid ku habboon jaakadaha dhamaadka sare ama codsiyada gaarka ah ee deegaanka.
Dib-u-habeynta ama wax ka beddelidda isku-darka
Adigoo soo bandhigaya midnimada (sida acricates) ama wakiilo iskuxiran oo iskuxiran (sida dhajinta ephoxy) si loo sameeyo shabakad iskuxiran oo iskutallaabta ah, iska caabbinta biyaha iyo awooda qarosiinta ee HEC ayaa la hagaajiyay. Tusaale ahaan, adoo adeegsanaya hydrophobiobiobiobiobiobiobiolically wax laga beddelay emulsions-ka polymer wuxuu kor u qaadi karaa xasilloonida iyo saamaynta qarosiinta ee emulsion.
Wax ka badalida jirka
Adigoo isticmaalaya xaynta xayeysiiska dusha ama tikniyoolajiyadda dusha sare, moloclobic-ka hydrophobic waxaa lagu daboolaa dusha sare ee HEC si loo sameeyo biyo-qabadyo gaar ah. Qaabkani waa mid dhexdhexaad ah oo ku habboon codsiyada shuruudaha sare ee xasilloonida kiimikada, sida cuntada iyo dawada.
Dib-u-habeynta Ururka Hydrophobic
Adoo soo bandhigaya qadar yar oo ah kooxo hydrophobic ah molecule-ka HEC moolka HEC, waxay ku sameysaa isku darka wadajirka ah ee xalka aqueous, taasna waxay ku fiicnaataa awoodda qaro weyn. Qaabkan ayaa si weyn loogu isticmaalaa horumarka dhumucda waxqabadka sare wuxuuna ku habboon yahay jaakadaha, kiimikooyinka saliida iyo meelaha kale.
Wax ka badalida hydrophobic eehydroxyetylyl cellWaa hab muhiim ah oo lagu horumarinayo waxqabadka arjigiisa, kaas oo kor u qaadi kara awooda qarosiinta, xasilloonida emulsition, xasilloonida biyaha, iska caabbinta biyaha iyo guryaha rhealologiyada. Hababka wax ka badalida ee caadiga ah waxaa ka mid ah girting Graddrophobic Gradting, compolumymization ama wax ka beddelidda isku-darka, wax ka badalida jirka iyo wax ka badalida ururka hydrophobic. Xulashada macquulka ah ee hababka wax-ka-beddelka ah ayaa kobcin kara waxqabadka HEC iyadoo loo eegayo shuruudaha codsiyada kaladuwan, si ay u ciyaaraan door weyn oo ah qaybo badan sida jaakadaha qaab dhismeedka, kiimikooyinka saliida, daryeelka shakhsi ahaaneed, iyo dawada.
