HEC ee rinjiga

Kariimka hydroxyetyl ​​(HEC) waa mid si aad ah loogu isticmaalo wax lagu daro warshadaha rinjiga, oo loo qiimeeyay guryahooda rinjiga, oo loo qiimeeyaa guryaheeda isku-darka ah ee gacan ka geysta sameynta, dalabka, iyo waxqabadka noocyada kala duwan ee rinjiga. Halkan waxaa ah dulmar guud oo ku saabsan codsiyada, howlaha, iyo tixgelinta HEC ee macnaha guud ee qaababka rinjiga:

1. Hordhac ku saabsan hydroxyetyl ​​cellulose (HEC) rinjiga

1.1 Qeexid iyo isha

Kariimka hydroxyetyl ​​ayaa ah polymer-ka-biyo-biyo-ku-mil-ka ah oo ka soo baxay celyulose iyada oo loo marayo falcelinta ethylenenene-ka oxide. Waxaa badanaa lagu dhajiyaa saxarka alwaaxa ama cudbiga waxaana loo shaqeeyaa si loo abuuro polymer leh polymer oo leh guryo kala duwan oo muuqaal ah iyo filim sameeya.

1.2 Doorka ee Qaadashada rinjiga

Qaadashada rinjiga, HEC waxay u adeegtaa ujeedooyin badan, oo ay ku jiraan dhumucda rinjiga, wanaajinta rinjiga, hagaajinta dareenkeeda, iyadoo la siinayo xasillooni, iyo kor u qaadida heerka guud iyo waxqabadka.

2. Hawlaha hydroxyetyly cellulose ee rinjiga

2.1 Moodiyeejiifier-ka-weyne iyo dhumuc weyn

HEC waxay u dhaqmeysaa sidii qaab-dhismeedka rheology iyo dhumuc weyn oo ku jira noocyada rinjiga. Waxay maamushaa viscosity of rinjiga, ka hortagga degitaanka midabka, iyo hubinta in rinjigu leeyahay joogteynta saxda ah ee codsiyada sahlan.

2.2 Fadhi

Sida xasillooni, HEC waxay gacan ka geysaneysaa joogteynta xasilloonida qaabeynta rinjiga, ka hortagga kala goynta wajiga iyo joogtaynta isku-dheellitirka inta lagu gudajiro kaydinta.

2.3 Biyo haynta biyaha

HEC waxay kor u qaadeysaa astaamaha haynta biyaha ee rinjiga, ka hortagga qallajinta si dhakhso leh. Tani waxay si gaar ah qiimo ugu leedahay rinjiga ku saleysan biyaha, taasoo u oggolaaneysa shaqo-la'aan ka fiican iyo yareynta arrimaha sida calaamadaha roller.

2.4 Guryaha abuurista filimka

HEC waxay gacan ka geysaneysaa sameynta filim joogto ah oo isku mid ah oo ku yaal dusha rinjiga. Filimkan wuxuu bixiyaa cimri dherer, kobcinta adhesion, wuxuuna wanaajiyaa muuqaalka guud ee dusha sare ee rinjiga.

3. Codsiyada rinjiga

3.1 Rinjiyeyaasha Latex

HEC waxaa badanaa loo isticmaalaa rinjiga cinjirka ama rinjiga biyaha ee ku saleysan si loo xakameeyo viscosity, hagaajinta xasilloonida rinjiga, iyo kor u qaadida waxqabadka guud ee muddada arjiga iyo qalajinta.

3.2 Rinjiga Emulsion

Marka lagu jiro rinjiga emulsion, oo ka kooban walxaha ku kala firidhsan walxaha ku kala firidhsan ee biyaha, HEC waxay u dhaqmayaan xasillooni iyo dhumuc, ka hortagga dejinta iyo bixinta joogtaynta la doonayo.

3.3 Xirmooyin qoraal ah

HEC waxaa loo adeegsadaa xaashiyaha qoraalka ah si loo wanaajiyo qaab dhismeedka iyo joogtaynta waxyaabaha dahabka ah. Waxay gacan ka geysaneysaa abuurista labis iyo dareen soo jiidasho leh dusha rinjiga.

3.4 Horumar iyo Xadhiga

Inpers-ka iyo kuwa Tarlas, HEC waxay gacan ka geysaneysaa xasilloonida sameynta, xakameynta sawirka, iyo guryaha qaab-dhismeedka filimka, hubinta diyaarinta substrate ee waxtarka leh.

4. Tixgalinta iyo taxadarka

4.1 Waafaqsanaanta

HEC waa inay la jaan qaadaan maaddooyinka kale ee rinjiga si looga fogaado arrimaha sida hoos u dhaca waxtarka, flosha, ama isbeddelada ku dhaca dareenka rinjiga.

4.2 U fiirsashada

U fiirsashada HEC ee qaababka rinjiga ayaa u baahan in si taxaddar leh loo xakameeyo si loo gaaro guryaha la soo diray ee la doonayo ee loo baahan yahay iyada oo aan si xun u saameynin dhinacyo kale oo rinjiga ah.

4.3 FARSAMADA FARSAMADA

In kasta oo HEC guud ahaan deggan tahay tirada ballaaran ee PH, waxaa muhiim ah in laga fiirsado PH-da abuurka rinjiga si loo hubiyo waxqabadka ugu habboon.

5. Gunaanad

Kariimka hydroxytyl waa wax lagu daro wax lagu daro warshadaha rinjiga, kuna tabaruca sameynta, xasilloonida, iyo adeegsiga noocyada kala duwan ee rinjiga. Hawlaha ay uruurinayso waxay ku habboon tahay rinjiga ku saleysan biyaha, rinjiga emulsion, iyo gogosha dharka lagu qoro, iyo kuwa kale. Qaab-dhismeedyadu waxay u baahan yihiin inay si taxaddar leh u tixgeliyaan is-waafajinta, feejignaanta, iyo ph si loo hubiyo in HEC ay u badato faa'iidooyinkeeda noocyada kala duwan ee rinjiga.
