Looj xim
Hydroxyethyl cellulose(HEC) yog dej-soluble, tsis-ionic polymer muab tau los ntawm cellulose. Hauv cov xim tsev zoo, HEC pabcuam feem ntau yog ib qho xim uas tuab dua, txhim kho nws cov ntawv thov.LATEX xim yog xim pleev xim. Zoo ib yam li cov xim acrylic, nws yog tsim los ntawm acrylic resin.
Cov xim loojxas looj yooj yim dua los ua haujlwm nrog thiab Dries ntau dua, tab sis nws tsis yog li ruaj khov raws li cov xim roj. LasX yog qhov zoo rau cov duab tha xim dav dav xws li phab ntsa thiab nthab.
Cov xim tsev zoo yog tam sim no ua nrog dej soluble puag thiab yog ua rau vinyl thiab acrylics.
Raws li qhov tshwm sim, lawv ntxuav tau yooj yim nrog dej thiab xab npum me me. Cov xim tsev zoo yog qhov zoo tshaj rau cov haujlwm sab nrauv, txij li lawv muaj qhov ruaj khov.
Daim ntawv thov ntawm hydroxyethyl cellulose hauv looj cov xim tsev
Qhov sib ntxiv ntawm cov xim muaj yees feem ntau feeb nyob rau hauv ntau feeb, txawm li cas los xij, lawv ua kom tseem ceeb thiab hloov hloov rau kev ua haujlwm ntawm cov xim yas. Peb tuaj yeem txheeb xyuas qhov kev ua haujlwm zoo kawg nkaus ntawm HEC thiab nws qhov tseem ceeb hauv kev pleev xim. Hydroxyethyl cellulose (HEC) muaj qee lub hom phiaj hauv kev tsim cov xim zoo ntawm cov xim av zoo uas cais nws los ntawm lwm yam kev sib txawv.
Rau cov xim looj xim manufacturers, siv hydroxyethyl cellulose (HEC) ua kom tiav ntau lub hom phiaj rau lawv cov duab. Ib qho haujlwm loj ntawm HEC hauv looj cov xim tsev yog tias nws tso cai rau cov nyhuv tuab tuab. Nws tseem ntxiv rau cov xim ntawm cov xim pleev xim, hec cov khoom ntxiv muab cov xim sib txawv ntxiv rau cov xim looj tes thiab muab cov xim hloov kho raws li cov neeg thov.
Daim ntawv thov ntawm Hec nyob rau hauv kev tsim cov xim looj cov xim ntxiv kuj tseem boosts tus nqi pH los ntawm kev txhim kho cov yam ntxwv tsis yog-ionic ntawm cov xim. Qhov no tso cai rau kev tsim cov chaw ruaj khov thiab muaj zog sib txawv ntawm cov xim yas, uas muaj ntau hom qauv. Muab cov cuab yeej sai thiab ua tau zoo thiab ua tau zoo thiab muaj txiaj ntsig yog lwm txoj haujlwm ntawm cov cellOthethyl cellulose. Cov xim tsev zoo, nrog rau kev sib ntxiv ntawm hydroxyethyl cellulose (HEC), tuaj yeem yaj sai thiab qhov no pab ua kom nrawm nrawm ntawm kev pleev xim. High-scalability yog lwm yam haujlwm ntawm HEC.
Ntxheej cov cellulose ether cov khoom tuaj yeem txhim kho los ntawm cov khoom nram qab no hauv looj cov xim khov:
· Zoo heev kev ua haujlwm thiab txhim kho kev sib kis tau.
Dej zoo khaws cia, nkaum lub hwj chim thiab zaj duab xis tsim ntawm cov khoom siv txheej yog txhim kho.
Cov nyhuv zoo tuab tuab, muab cov txheej txheej ua kom zoo dua qub thiab txhim kho cov txhuam kom tiv thaiv cov txheej.
· Zoo sib xws heev nrog rau polymer emulsions, ntau yam ntxiv, pigments, thiab filers, thiab lwm yam.
· Zoo rheological cov khoom, kev faib tawm thiab solubility.
