Indlela yokusasaza i-hydroxythyl selluplose?

I-HydroxyEtheetheetheetheetheethy (Hec) i-polymer esetyenziswe ngokubanzi kumashishini ahlukeneyo ngenxa yepropathi yayo eyahlukileyo efana nokugcinwa, ukugcinwa kwamanzi, kunye nobuchule bokwenza ifilimu. Ukusasaza i-HEC ngokufanelekileyo kubalulekile ukuqinisekisa ukusetyenziswa kakuhle kwizicelo ezinjengeepeyinti, i-cosmetics, amayeza, kunye nezixhobo zokwakha.

I-1. Ukuqonda i-hydroxyyl seluplose (hec):
I-Hec yi-polymer engeyiyo i-ionic, i-poly-all-allmer ethathwe kwi-seluplose.
Yenza izisombululo ezicacileyo emanzini, ubonakalisa indlela yokuziphatha ye-pseudoplastic, intsingiselo yokufakwa kwayo kuncipha ngokukhula kwenqanaba le-Shear.

2. Ukukhetha isoyile:
Amanzi sesona seluth ixhaphakileyo esiqhelekileyo sokusasaza i-hec ngenxa yomoya wayo ophezulu.
Iqondo lobushushu kunye ne-PH ye-solvent inokuphembelela ukusasazeka kwe-hec. Ngokwesiqhelo, ukungathathi hlangothi ukuya kancinci i-alkaline PH kukhethwa.

3. Ukulungiselela ukusasazeka:
Sebenzisa amanzi e-deeerser okanye amanzi okunciphisa ukuncipha okunokuchaphazela ukusasazeka kwe-hec.
Gcina iqondo lobushushu elinqwenelekayo lenkqubo yokupheliswa, iqondo lobushushu kwigumbi lokuhlala amaqondo obushushu aphezulu (malunga ne-20 ukuya kwengama-20 ° C).

4. Iindlela zokusasazeka:
a. Ukudityaniswa kwesandla:
-Ilungele izicelo ezincinci.
-Ngcotha i-hec powder ukuya kwisinyibilikisi ngelixa ushukumisa ngokuqhubekayo ukuthintela ukuncama.
- Qinisekisa ukuba ukumanzi okufanelekileyo komgubo ngaphambi kokunyusa ubunzulu bobuxube.

b. Ukuvuselela oomatshini:
-Fumana i-stirren yomatshini exhotywe i-blade efanelekileyo okanye i-impleller.
-Uhlengahlengisa isantya esibonisa isantya sokufezekisa ukusasazeka okungafaniyo ngaphandle kokubangela igwebu eligqithisileyo okanye ingeniso yomoya.

c. Ukudibana okungaphezulu
-Shasha abaxube-sebenzisa i-shear ephezulu njengabaxumi baseHomogenizers okanye abasasazi abahamba ngesantya esiphezulu sokusasazeka ngokufanelekileyo.
- Lawula inqanaba leShear ukuthintela ukonakaliswa kweemolekyuli.

d. Ulawulo:
-Sebenzisa amandla e-ultrasonic ukwaphula i-Aggomeramest kunye nokuphucula ukusasazeka.
-Sebenzisa iiparamitha zokuzalwa (rhoqo, amandla, ixesha) ukunqanda ukugqithisa okanye ukonakala kwesisombululo.

5. Iingcebiso zokusasazwa ngempumelelo:
Qinisekisa ukuba i-hec powder yongezwa ngokuthe chu ukukhusela i-hump.
Kulumkele ukutshintsha ngesiquphe kwiqondo lobushushu okanye i-phle ngexesha lokusasazeka, njengoko kunokubachaphazela u-Hec Solubi.
Vumela ixesha elaneleyo lokungasebenzi kakuhle kunye nokusasazeka kwamasuntswana eeHec.
Ukubeka iliso kwi-viscofity ngexesha lokusasazeka ukufezekisa ukungqinelana okufunayo.
Sebenzisa izixhobo ezifanelekileyo kunye neendlela ngokwesikali kunye neemfuno zesicelo.

6. Ulawulo loMgangatho:
Yenza uhlolo olubonakalayo lwawo nawuphi na amasuntswana angahambiyo okanye ukwenziwa kwejeli nje.
Ukulinganisa i-viscofity usebenzisa i-vismemeter yokuqinisekisa ukungqinelana kunye nenkcazo oyifunayo.
Ukuqhutywa kweemvavanyo ze-Rheiological ukuvavanya indlela yokuziphatha yokuhamba kunye nokuzinza kwe-hec yokusasazeka.

I-7. Ukugcina nokusingatha:
Gcina isalathiso se-hec kwizikhongozeli ezicocekileyo, ezitywiniweyo zokutyunyuzwa ukhusela ungcoliseko kunye ne-inceress yokufuma.
Kulumkele ukuvezwa kwexesha elide kubushushu obukhulu okanye ukukhanya kwelanga ngqo, okusenokuwonakalisa i-polymer.
Iileyibheli izikhongozeli ngolwazi olufanelekileyo kubandakanya inombolo ye-batch, uxinzelelo kunye neemeko zokugcina.

8. Ukuqwalaselwa kukhuseleko:
Landela izikhokelo zokhuseleko xa uphatha umgubo kunye nezisombululo.
Sebenzisa izixhobo ezifanelekileyo zokhuselo (i-PPE) njengeigloves kunye ne-goggles yokhuseleko.
Kunqande ukuphefumla kwamasuntswana othuli ngokusebenza kwindawo enomoya okanye usebenzisa ukhuseleko lokuphefumla ukuba kukho imfuneko.
Ukusasaza i-hydroxyythl seluplose ifuna ukuthathelwa ingqalelo ngononophelo ngokukhethwa kwesolutho, iindlela zokusasazwa, amanyathelo olawulo lomgangatho, kunye namanyathelo okhuseleko. Ngokulandela ezi ziKhokelo, unokuqinisekisa ukusebenza kakuhle kunye nozinzo zosasazo lwe-hec kwizicelo ezahlukeneyo zemveliso.
