Rinjiga cinjirka ah (sidoo kale loo yaqaan rinjiga biyaha ku salaysan) waa nooc ka mid ah rinjiga leh biyaha sida dareeraha, kaas oo inta badan loo isticmaalo qurxinta iyo ilaalinta derbiyada, saqafka iyo meelaha kale. Habka rinjiga cinjirka waxaa badanaa ka kooban emulsion polymer, pigment, buuxinta, wax lagu daro iyo walxo kale. Waxaa ka mid ah.Hydroxyethyl cellulose (HEC)waa dhumuc muhiim ah waxaana si weyn loogu isticmaalaa rinjiga cinjirka. HEC kaliya ma hagaajin karto viscosity iyo rheology ee rinjiga, laakiin sidoo kale waxay hagaajin kartaa waxqabadka filimka rinjiga.
1. Tilmaamaha aasaasiga ah ee HEC
HEC waa iskudhis biyo-milmi leh oo laga beddelay cellulose leh dhumuc wanaagsan, ganaax iyo sifooyin samaynta filim. Silsiladdeeda molecular waxa ay ka kooban tahay kooxaha hydroxyethyl, kuwaas oo awood u siinaya in ay ku milmaan biyaha oo ay sameeyaan xal viscosity sare leh. HEC waxay leedahay hydrophilicity xooggan, taas oo u sahlaysa inay door ka qaadato xasilinta joojinta, hagaajinta rheology iyo hagaajinta waxqabadka filimka ee rinjiga cinjirka ah.
2. Isdhexgalka ka dhexeeya HEC iyo emulsion polymer
Qaybta xudunta u ah rinjiga cinjirka ah waa emulsion polymer (sida acrylic acid ama ethylene-vinyl acetate copolymer emulsion), kaas oo sameeya qalfoofka ugu weyn ee filimka rinjiga. Is dhexgalka ka dhexeeya AnxinCel®HEC iyo polymer emulsion ayaa inta badan lagu muujiyaa dhinacyada soo socda:
Degenaansho la wanaajiyey: HEC, dhumuc ahaan ahaan, waxay kordhin kartaa viscosity ee rinjiga cinjirka waxayna gacan ka geysan kartaa xasilinta qaybaha emulsion-ka. Gaar ahaan emulsion-ka polymer-ka-hooseeya, ku-darka HEC wuxuu yarayn karaa qulqulka qaybaha emulsion iyo hagaajinta xasilloonida kaydinta rinjiga.
Xeerarka Rheological: HEC waxay hagaajin kartaa sifooyinka rheological ee rinjiga cinjirka ah, si ay u yeelato waxqabadka dahaarka ee wanaagsan inta lagu jiro dhismaha. Tusaale ahaan, inta lagu guda jiro habka rinjiyeynta, HEC waxay hagaajin kartaa hantida silbashada ee rinjiga oo ka fogaato daadinta ama hoos u dhigida daaha. Intaa waxaa dheer, HEC waxay sidoo kale xakameyn kartaa soo kabashada rinjiga waxayna kor u qaadi kartaa isku-duubnaanta filimka rinjiga.
Hagaajinta waxqabadka daahan: Ku-darka HEC wuxuu hagaajin karaa dabacsanaan, dhalaalid iyo caabbinta xoqidda. Qaab dhismeedka molecular ee HEC wuxuu la falgali karaa emulsion polymer si kor loogu qaado qaab dhismeedka guud ee filimka rinjiga, taas oo ka dhigaysa cufan oo sidaas awgeed hagaajinaysa cimrigiisa.
3. Isdhexgalka ka dhexeeya HEC iyo pigments
Midabka rinjiyada cinjirka ah sida caadiga ah waxaa ka mid ah midabada aan organic ahayn (sida titanium dioxide, budada mica, iwm.) iyo midabada organic. Is dhexgalka ka dhexeeya HEC iyo pigments ayaa inta badan ka muuqda dhinacyada soo socda:
Kala firdhisanaanta midabka: Saamaynta dhumucda ee HEC waxay kordhisaa viscosity ee rinjiga cinjirka, kaas oo si fiican u kala firdhi kara qaybaha midabka kana fogaanaya isku-darka midabka ama roobka. Gaar ahaan qaar ka mid ah qaybaha midabka midabka leh, qaab dhismeedka polymer ee HEC wuxuu ku duubi karaa dusha sare ee midabka si looga hortago qallafsanaanta qaybaha midabka, taas oo hagaajinaysa kala firdhisanaanta midabka iyo isku-duubnaanta rinjiga.
Xoogga isku dhafka ah ee u dhexeeya midabka midabka iyo filimka daahan:HECmolecules waxay soo saari karaan xayeysiis jireed ama ficil kiimiko ah oo leh dusha sare ee midabka, waxay xoojiyaan xoogga isku-xidhka ee u dhexeeya midabka iyo filimka daahan, oo ka fogaadaan ifafaale ee daadinta midabka ama luminta dusha sare ee filimka daahan. Gaar ahaan rinjiga cinjirka ah ee waxqabadka sare leh, HEC waxay si wax ku ool ah u wanaajin kartaa iska caabbinta cimilada iyo iska caabbinta UV ee midabka iyo kordhinta nolosha adeegga daahan.
4. Isdhexgalka HEC iyo buuxinayaasha
Qaar ka mid ah buuxinta (sida calcium carbonate, budada talcum, macdanta silicate, iwm.) ayaa badanaa lagu daraa rinjiga cinjirka si loo hagaajiyo rheology ee rinjiga, hagaajinta awoodda qarinta ee filimka daahan iyo kordhinta waxtarka qiimaha rinjiga. Is dhexgalka ka dhexeeya HEC iyo buuxinayaasha ayaa ka muuqda dhinacyada soo socda:
Joojinta buuxinta: HEC waxay ku hayn kartaa buuxintii lagu daray rinjiga cinjirka si isku mid ah u kala firdhiso iyada oo loo marayo saamaynteeda dhumucdeeda, iyada oo ka ilaalinaysa buuxinta inay degto. Buuxiyeyaasha leh cabbirrada walxaha waaweyn, saameynta dhumucda ee HEC ayaa si gaar ah muhiim u ah, taas oo si wax ku ool ah u ilaalin karta xasilloonida rinjiga.
Dhallaanka iyo taabashada dahaarka: Ku-darka buuxinta waxay inta badan saamaysaa dhalaalka iyo taabashada dahaarka. AnxinCel®HEC waxay wanaajin kartaa waxqabadka muuqaalka dahaarka iyadoo hagaajinaysa qaybinta iyo habaynta buuxinyaasha. Tusaale ahaan, kala firdhinta lebiska ee walxaha wax-buuxiyaha ah waxay kaa caawineysaa in la yareeyo qallafsanaanta dusha dahaarka iyo hagaajinta fidsanaanta iyo dhalaalka filimka rinjiga.
5. Isdhexgalka ka dhexeeya HEC iyo waxyaabaha kale ee lagu daro
Nafaqada rinjiga cinjirka waxa kale oo ka mid ah waxyaabo kale oo lagu daro, sida kuwa defoamerayaasha, waxyaalaha ilaaliya, walxaha qoynta, iwm
Is dhexgalka u dhexeeya defoamers iyo HEC: Shaqada defoamers waa in la yareeyo xumbo ama xumbo rinjiga, iyo sifooyinka sare ee viscosity ee HEC waxay saameyn kartaa saamaynta defoamers. HEC-da xad-dhaafka ah ayaa laga yaabaa inay ku adkeyso in foamer-ku uu si buuxda u saaro xumbo, sidaas darteed saameynaya tayada dusha sare ee rinjiga. Sidaa darteed, qaddarka HEC ee lagu daray waxay u baahan tahay in la isku duwo qadarka foamer-ka si loo gaaro saameynta ugu fiican.
Isdhexgalka ka dhexeeya walxaha ilaaliya iyo HEC: Doorka ilaalinta waa in laga hortago koritaanka noolaha ee rinjiga iyo kordhinta wakhtiga kaydinta rinjiga. Sida polymer-ka dabiiciga ah, qaab-dhismeedka molecular ee HEC ayaa laga yaabaa inay la falgalaan waxyaabaha ilaaliya qaarkood, oo saameeya saameynteeda ka-hortagga daxalka. Sidaa darteed, waxaa muhiim ah in la doorto qalab ilaalin ah oo ku habboon HEC.
DoorkaHECRinjiga cinjirka ma aha oo kaliya dhumuc, laakiin is dhexgalka uu la leeyahay emulsions polymer, pigments, buuxinta iyo waxyaabo kale ayaa si wadajir ah u go'aamiya waxqabadka rinjiga cinjirka. AnxinCel®HEC waxay wanaajin kartaa sifooyinka rheological ee rinjiga cinjirka ah, waxay wanaajisaa kala firdhisanaanta midabada iyo buuxinayaasha, waxayna wanaajisaa sifooyinka farsamada iyo adkeysiga dahaarka. Intaa waxaa dheer, saameynta isku-dhafka ah ee HEC iyo waxyaabaha kale ee lagu daro waxay sidoo kale saameyn muhiim ah ku leeyihiin xasilloonida kaydinta, waxqabadka dhismaha iyo muuqaalka daboolka ee rinjiga cinjirka. Sidaa darteed, naqshadeynta caanaha rinjiga cinjirka, xulashada macquulka ah ee nooca HEC iyo qadarka dheeriga ah iyo dheelitirka isdhexgalka maaddooyinka kale ayaa fure u ah hagaajinta waxqabadka guud ee rinjiga cinjirka.
