Doorashada dhumucda saxda ah ee hydroxyethyl cellulose (HEC) ee rinjiga cinjirka ah waxay ku lug leedahay tixgelinta arrimo kala duwan, oo ay ku jiraan sifooyinka rheological ee la rabo, waafaqsanaanta qaybaha kale ee rinjiga, iyo shuruudaha gaarka ah ee codsiga. Hagahan dhammaystiran waxa uu dabooli doonaa dhinacyada muhiimka ah si uu kaaga caawiyo in aad go'aan xog ogaalnimo leh ka gaadho doorashada dhumucda HEC ee ugu habboon samaynta rinjiga cinjirka.
1. Horudhaca Rinjiga Dhumucda Latex:
1.1 Shuruudaha Rheological:
Rinjiga cinjirka wuxuu u baahan yahay rheology wax ka beddelka si loo gaaro joogteynta la rabo, xasilloonida, iyo sifooyinka codsiga. HEC waa doorasho caadi ah oo ay ugu wacan tahay waxtarkeeda ee dhumucda hababka biyaha ku salaysan.
1.2 Muhiimadda Dhumucda:
Waxyaalaha dhumucdiisuna waxay kor u qaadaan viscosity rinjiga, ka hortagga hoos u dhaca, hagaajinta daboolka buraashka, iyo siinta hakin wanaagsan ee midabada iyo buuxinta.
2. Fahamka Hydroxyethyl Cellulose (HEC):
2.1 Qaab dhismeedka Kiimikada iyo Guryaha:
HEC waa polymer biyo-milmi leh oo ka yimid cellulose. Qaab dhismeedkeeda gaarka ah waxa ay siisa dhumucyada guryaha iyo xasiloonida rinjiga cinjirka.
2.2 Fasalada HEC:
Heerarka HEC ee kala duwan ayaa jira, kuwaas oo ku kala duwan miisaanka molecular iyo heerarka beddelka. Miisaanka unugyadu sareeyo iyo beddelaadku waxa ay keeni karaan korodhka waxtarka dhumucda.
3. Arrimaha Saamayn ku leh Xulashada HEC:
3.1 Samaynta Rinjiga Latex:
Tixgeli qaabka guud, oo ay ku jiraan nooca cinjirka, midabada, buuxinta, iyo waxyaabaha lagu daro, si loo hubiyo in waafaqsanaanta HEC ee la doortay.
3.2 Profile Rheological ee La Rabo:
Qeex shuruudaha rheological ee gaarka ah ee rinjigaaga cinjirka ah, sida khafiifinta xiirta, simida, iyo iska caabbinta biyaha.
4. Tixgelinta muhiimka ah ee xulashada HEC:
4.1 Viscosity:
Dooro darajada HEC oo bixisa viscosity-ka la rabo qaabka rinjiga ugu dambeeya. Samee cabirrada viscosity ee xaaladaha ku habboon codsiga.
4.2 Xidid khafiif ah noqodhibaato:
Qiimee habdhaqanka xiirid-xiirid, kaas oo saameeya fududaynta codsiga, simida, iyo dhismaha filimka.
5. Waafaqid iyo Degenaansho:
5.1 Waafaqsanaanta Latex:
Hubi in HEC ay la jaan qaadayso polymer-ka cinjirka ah si looga fogaado arrimaha sida kala goynta wajiga ama luminta xasiloonida.
5.2 pH dareenka:
Tixgeli dareenka pH ee HEC iyo saamaynta ay ku leedahay xasilloonida. Dooro darajo ku habboon qiyaasta pH ee rinjiga cinjirkaaga.
6. Farsamooyinka Codsiga:
6.1 Codsiga burushka iyo rullalusha:
Haddii buraashka iyo rullalulatu ay caadi yihiin, dooro darajada HEC oo bixisa buraash/jiidid wanaagsan oo iska caabin ah.
6.2 Codsiga buufin:
Codsiyada buufinta, dooro heerka HEC ee ilaalinaya xasilloonida inta lagu jiro atomization oo hubisa xitaa dahaarka.
7. Tijaabada iyo Xakamaynta Tayada:
7.1 Qiimaynta Shaybaadhka:
Samee tijaabooyin shaybaar oo dhamaystiran si aad u qiimayso waxqabadka darajooyinka HEC ee kala duwan marka loo eego shuruudaha u ekaysiinaya codsiga aduunka dhabta ah.
7.2 Tijaabooyinka Goobta:
Samee tijaabooyin gudaha ah si aad u ansixiso natiijooyinka shaybaarka oo aad ilaaliso waxqabadka HEC ee la doortay ee xaaladaha codsiga rinjiga dhabta ah.
8. Tixgelinta Nidaaminta iyo Deegaanka:
8.1 U Hogaansanaanta Nidaaminta:
Hubi in HEC-da la xushay ay u hoggaansanto shuruudaha sharciyeynta ee rinjiyeynta, iyadoo la tixgelinayo waxyaabaha ay ka midka yihiin VOC (ka kooban xeryahooda organic kacsan).
8.2 Saamaynta Deegaanka:
Qiimee saamaynta deegaanka ee HEC oo dooro darajooyin leh cawaaqibka deegaanka ee ugu yar.
9. Tixgelinta Ganacsiga:
9.1 Qiimaha:
Qiimee waxtarka-wax-ku-oolnimada ee darajooyinka HEC ee kala duwan, iyadoo la tixgelinayo waxqabadkooda iyo saameynta guud ee samaynta rinjiga.
9.2 Silsiladda Alaabta iyo Helitaanka:
Tixgeli helitaanka iyo isku halaynta silsiladda sahayda ee HEC ee la doortay, hubinta tayada joogtada ah.
10. Gabagabo:
Doorashada dhumucda saxda ah ee HEC ee rinjiga cinjirka waxay ku lug leedahay qiimeyn dhamaystiran oo shuruudaha rheological, waafaqid, farsamooyinka codsiga, iyo tixgalinta sharciyeynta. Markaad tixgaliso arrimahan, waxaad dooran kartaa darajada HEC oo si wanagsan u buuxinaysa baahiyaha samaynta rinjiga cinjirka, hubinta waxqabadka joogtada ah iyo tayada xaaladaha kala duwan ee codsiga.
