Hydrophobic wax laga beddelay byroxylyl (HEC) waa nooc ka mid ah wax laga beddelay iyada oo la soo bandhigo kooxaha dareeraha ah (sida silsiladda alkroxytyl cellulose (HEC). Qoraalka noocan ahi wuxuu isku daraa guryaha hydophilic ee hydroxyetyl blulose oo leh astaamaha hydrophobic ee kooxaha hydrophobic oo si weyn loogu isticmaalo jaakadaha, saabuunta, xargaha waxyaabaha la isku qurxiyo iyo daroogada.
1. Habka isku-dhafka ah ee lagu beddelo hydrophobioxytytyl cellulose
Isku-darka isku-darka hydrophobioxyExytyl bylulose waxaa inta badan lagu sameeyaa hababka soo socda:
1.1 Falcelinta Eastriction
Qaabkan ayaa ah in laga falgalo byroxykyl cell-ka kiimikada ah ee kiimikada ah (sida acids froms froms acid, chlorides, iwm.) Si aad u soo bandhigto kooxo hydrophobic-ka ah unugyada unugyada unugyada. Fal-celinta Eastic-ka oo aan si muuqata u soo bandhigi karin kooxo hydrophobic ah, laakiin sidoo kale waafajisaa hawo-mareenka iyo saamaynta qarosiinta ee pomoomers. Xaaladaha falcelinta ee nidaamka isku-darka, sida heerkulka, waqtiga, dareeraha falcelinta iyo soosaarka, waxay saameyn ku yeelan doontaa waxqabadka wax soo saarka ugu dambeeya.
1.2 QIIMAYNTA
Qaabkan, kooxda hydroxyl waa kooxda hydroxytylylyl byluleyl waxaa lagu beddelaa koox hydrophobic ah (sida alkyl, phenyl, iwm.). Faa'iidada qaabkan ayaa ah in xaaladaha isku-darka ay yihiin kuwo dhexdhexaad ah, astaamaha qaabdhismeedka ee hydroxyyl cellulose si fiican ayaa loo ilaalin karaa, iyo sheyga wax laga beddelay ayaa sida caadiga ah leh xadhiga iyo saamaynta qarosiinta.
1.3 Falcelinta CopolumyMerization
AQOONSIGA AQOONSIGA GUUD (sida acrylic acid, acrylate, iwm.), Polymer cusub oo leh hydrophobicity waa la diyaarin karaa. Qaabkani wuxuu gaari karaa xakamayn sax ah oo ku saabsan waxqabadka qarosiinta ee unugyada iyadoo la hagaajinayo saamiga monomers kala duwan.
1.4 Falcelinta Xiriirinta
Xeryadaha hydrophobic waa kiimiko ku xiraya qaab dhismeedka hydroxyetyl bylulose si ay u sameeyaan baloogyo hydrophobic ama qaybo. Qaabkani wuxuu kor u qaadi karaa xasilloonida kuleylka iyo dhaqdhaqaaqa dusha sare ee hydrophobioxykykyl, oo ku habboon shuruudaha waxqabadka sare ee gaarka ah.
2. Habka qarosiinta ee hydrophobiotically wax laga beddelay hydroxytyl cellulose
Habka qarka u weyn ee lagu beddelo hydroxytylylureyl wuxuu inta badan ka kooban yahay dhinacyada soo socda:
2.1 Kordhinta is dhexgalka bulshada
Soo bandhigista kooxaha hydrophobic waxay kor u qaadaan is-dhexgalka ka dhexeeya molecules cholecules, gaar ahaan jawiga aqueous, halkaas oo ay isku daraan inay isku daraan isku darka weyn ee molitalar. Saamayntan isku-darka ah waxay horseedaa koror ku saabsan jawiga xalka, sidaas darteedna muujinaya hanti adag.
2.2 Is dhexgalka-Hydrophilic-Hydrophobic
Kooxaha hydroxytyl (sida hydroxyetyl) iyo kooxaha hydrophobic (sida alkyl, phenyl, iwm.) In ka mid ah hydrophobioxykylly waxay ka wada shaqeeyaan is-dhexgalka unugyada hydrophilic-fooddrophicic-ka Wejiga aqueous, qaybta biyaha kubadaha ayaa si adag ula falgalaya moleekuleyaasha biyaha, halka qaybta dareeraha ah ay midba midka kale ka soo jiidato saameynta hydrophobic, oo sii kordhaya cufnaanta qaab-dhismeedka ee u dhexeeya moleekules-ka sidaas darteedna kordhinta viscosity.
2.3 Dhisidda qaab dhismeedka shabakadda ee xalka
Dib-u-habeynta dareeraha ah ka dib, qaab dhismeedka silsiladda molikalar ayaa laga yaabaa inuu isbedelo, sameynta qaab dhismeedka shabakadda saddex-geesoodka ah. Qaab dhismeedkan ayaa si weyn u hagaajin kara Vacolasit-ka iyo awoodda qarosiinta ee xalka iyada oo loo marayo isku xirka jirka ee ka dhexeeya moleekules.
2.4 Way fududahay in la sameeyo qaab dhismeedka u eg ee gel-sida
Sababo la xiriira soo bandhigida kooxaha hydrophobic, hydrophobioxytytytyl bylulose waxay leedahay guryo wanaagsan oo lagu helo. Xaaladaha ku habboon, sida isbeddelada heerkulka, pH ama fiirsashada, kooxaha hydrophopbic wax laga beddelay waxay sababi karaan qaab dhismeedka geesoodka geedaha, kaas oo sidoo kale muujinta guryaha qaro weyn leh.
3. Codsashada hydrophobiobiolically wax laga beddelay hydroxytyl cell
Hydrophobic wax laga beddelay byroxykyl bylulose waxaa si weyn loogu isticmaalaa beerooyin badan oo warshadeed, gaar ahaan xaaladaha halka dhumucda, hagaajinta rheilogical iyo horumarka xasilloonida loo baahan yahay:
3.1 Xirmooyinka iyo rinjiga
Warshadaha jaakadaha, hydrophobioxyedyelyl byroxylyl ayaa hagaajin kara guryaha rdroxyl-ka, eryida iyo waxqabadka dhismaha ee daaha, inta ay soo hagaageyso iska caabbinta biyaha iyo iska caabbinta wasakhda ee daboolka.
3.2 Nadaafadda iyo saabuunta
Ku darista hydrophobioxytyl byroxykyl byroxykyl si ku-meel-biyoodka ayaa si wax ku ool ah u hagaajin kara qaboojinta saabuunta, taas oo ka dhigaysa mid deggan oo fududahay in la xakameeyo inta lagu jiro isticmaalka.
3.3 COSMETICS
In duurka la isku qurxiyo, hydrophobioxytytyl byroxyl byluxyl waxaa badanaa loo isticmaalaa sida dhumuc iyo wakiillo laga joojiyo.
3.4 Shirkadda daroogada
Sababo la xiriira dhumucdeeda iyo dadaawga wanagsan, biyo-mareenka sicir-bararka hydroxyetyl ayaa sidoo kale si ballaaran loogu bartay si loogu isticmaalo nidaamyada sii deynta maandooriyaha, oo si wax ku ool ah u xakameyn kara heerka siideynta daroogada.
Adigoo soo bandhigaya kooxaha hydrophobic-ka ah waxoogaa hydrophobic ah oo wax laga beddelay byroxykyl kaliya ma bixinayso kaliya hydroxykyl cell saameyn culus, laakiin sidoo kale waxay ka dhigeysaa inay muujiso waxqabadyo aad u wanaagsan codsiyada kala duwan. Qaabka qaro weyn ee uu inta badan ku xidhan yahay is-dhexgalka kooxaha hydrophobic iyo kooxaha biyo-baxa, isku-darka isku-darka molikalikada iyo isbeddelada qaab dhismeedka xalka. Iyadoo qoto dheer oo cilmi-baaris ah, habka isku-darka ah iyo maaddada arjiga iyo maaddada arjiga ee hydrophobioxytyl byluxyl cellulose ayaa si dheeraad ah loo ballaarin doonaa, iyadoo rajada suuqa ballaaran.
