HEMC kwa Putty
HEMC, kapena hydroxyethyl methyl cellulose, ndiye chinthu chofunikira kwambiri pakupanga ma putty. Ndi polima yosungunuka m'madzi yomwe imagwiritsidwa ntchito ngati chowonjezera, chomangira, komanso chosinthira rheology. HEMC imachokera ku cellulose ndipo ndi yopanda ionic, yopanda poizoni, komanso yosayaka.
Mu mapangidwe a putty, HEMC imagwiritsidwa ntchito ngati thickener ndi binder. Kuphatikizika kwa HEMC kusakaniza kumathandiza kupititsa patsogolo ntchito ya putty ndikulola kulamulira bwino kwa madzi. Izi ndizofunikira chifukwa madzi omwe ali mu putty amakhudza kusasinthika kwake, nthawi yake, ndi mphamvu yomaliza.
Chimodzi mwamaubwino ofunikira a HEMC pamapangidwe a putty ndikutha kwake kupititsa patsogolo kumamatira kwa putty kumagawo. HEMC imagwira ntchito ngati chomangira, ndikupanga mgwirizano wamphamvu pakati pa putty ndi pamwamba pake. Izi ndizofunikira makamaka pamagwiritsidwe ntchito pomwe putty idzavutitsidwa kwambiri, monga kudzaza mipata ndi ming'alu ya makoma.
HEMC imathandizanso kupewa kupatukana kwa zigawo zosiyanasiyana mu kapangidwe ka putty. Izi ndizofunikira chifukwa putty yosakanikirana bwino imatsimikizira kuti idzakhala ndi katundu wokhazikika ndipo idzatha kuchita momwe ikufunira.
Phindu lina la HEMC pamapangidwe a putty ndikutha kwake kuwongolera kukana kwa kuzizira kwa putty. Madzi akaundana, amakula, zomwe zingayambitse kuwonongeka kwa putty. HEMC imathandiza kupewa izi powonjezera kusungunuka kwa putty ndi kuchepetsa kuchuluka kwa madzi omwe amapezeka kuti asungunuke.
HEMC imagwiranso ntchito mu rheology of putty formulations. Rheology ndi kuphunzira kuyenda ndi kusinthika kwa zinthu. Mwa kusintha kuchuluka kwa HEMC mu kusakaniza, n'zotheka kulamulira rheological katundu wa putty. Izi angagwiritsidwe ntchito kulenga putties ndi makhalidwe enieni, monga mkulu mamasukidwe akayendedwe kapena thixotropy.
Kuphatikiza pa ntchito yake pakupanga ma putty, HEMC imagwiritsidwanso ntchito pazinthu zina zosiyanasiyana. Nthawi zambiri amagwiritsidwa ntchito ngati chowonjezera komanso chokhazikika muzakudya, komanso pazinthu zosamalira anthu monga ma shampoos ndi mafuta odzola. HEMC imagwiritsidwanso ntchito ngati thickener ndi binder popanga utoto wa latex.
Ponseponse, HEMC ndi gawo lofunikira pamapangidwe a putty. Kuthekera kwake kupititsa patsogolo magwiridwe antchito, kumamatira, kukana kuzizira, komanso mawonekedwe a rheological a putties kumapangitsa kuti ikhale gawo lofunikira pamapulogalamu ambiri omanga.
