Hydroxyethyl Methyl Cellulose (HEMC)

Hydroxyethyl methyl cellulose (HEMC) ndi polima yosungunuka m'madzi yochokera ku cellulose.Ndiwopanda ionic, wopanda poizoni, komanso wosayaka moto womwe umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana komanso ogula.HEMC imayamikiridwa chifukwa cha kuthekera kwake kochita zinthu ngati thickener, binder, ndi rheology modifier muzinthu zambiri.

HEMC imapangidwa ndi kusintha kwachilengedwe ulusi wa cellulose.Pochita izi, ulusi wa cellulose umathandizidwa ndi sodium hydroxide kupanga alkali cellulose.Ethylene oxide ndiye amawonjezeredwa kusakaniza, komwe kumagwirizana ndi cellulose kupanga hydroxyethyl cellulose.Pomaliza, methyl chloride imawonjezedwa kusakaniza kuti ipange HEMC.

HEMC imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo zomangamanga, chakudya, chisamaliro chaumwini, ndi mankhwala.Chimodzi mwazofunikira za HEMC ndikumanga, komwe chimagwiritsidwa ntchito pazinthu zosiyanasiyana monga matope osakaniza owuma, ma putty, zomatira matailosi, ndi zinthu za gypsum.

M'matope osakaniza owuma, HEMC imagwiritsidwa ntchito ngati thickener, binder, ndi kusunga madzi.Imathandiza kupititsa patsogolo ntchito ya matope ndikupangitsa kuti madzi azikhala bwino.Izi ndizofunikira chifukwa madzi omwe ali mumatope amakhudza kusasinthasintha kwake, nthawi yake, ndi mphamvu yomaliza.

Mu putties, HEMC imagwiritsidwa ntchito ngati thickener ndi binder.Kuphatikizika kwa HEMC kusakaniza kumathandiza kupititsa patsogolo ntchito ya putty ndikulola kulamulira bwino kwa madzi.HEMC imathandizanso kupewa kupatukana kwa zigawo zosiyanasiyana mu mapangidwe a putty, ndipo imathandizira kumamatira kwa putty ku magawo.

Mu zomatira matailosi, HEMC imagwiritsidwa ntchito makamaka ngati chosungira madzi.Kuphatikizika kwa HEMC kusakaniza kumathandizira kupititsa patsogolo ntchito zomatira komanso kulola kuwongolera bwino kwa madzi.HEMC imathandizanso kupewa kupatukana kwa zigawo zosiyanasiyana pakupanga zomatira, ndipo imapangitsa kuti zomatira zikhale bwino pamagawo.

M'zinthu za gypsum, HEMC imagwiritsidwa ntchito ngati thickener, binder, ndi wothandizira madzi.Zimathandizira kukonza magwiridwe antchito amtundu wa gypsum ndikuwongolera bwino zomwe zili m'madzi.Izi ndizofunikira chifukwa madzi amtundu wa gypsum amakhudza nthawi yake yokhazikika komanso mphamvu yomaliza.

Muzakudya, HEMC imagwiritsidwa ntchito ngati thickener, stabilizer, and emulsifier.Amagwiritsidwa ntchito mumitundu yosiyanasiyana yazakudya, kuphatikiza sosi, mavalidwe, ndi mkaka.HEMC imayamikiridwa chifukwa cha kuthekera kwake kukonza mawonekedwe ndi kukhazikika kwa zinthuzi.

M'zinthu zothandizira anthu, HEMC imagwiritsidwa ntchito ngati thickener, stabilizer, ndi emulsifier.Amagwiritsidwa ntchito pazinthu zosiyanasiyana zosamalira anthu, kuphatikiza ma shampoos, zowongolera, ndi zodzola.HEMC imayamikiridwa chifukwa cha kuthekera kwake kukonza mawonekedwe ndi kukhazikika kwa zinthuzi.

Pazamankhwala, HEMC imagwiritsidwa ntchito ngati chomangira komanso chosokoneza.Amagwiritsidwa ntchito popanga mapiritsi kuti apititse patsogolo mphamvu zamakina a piritsi komanso kuti azitha kuwonongeka komanso kusungunuka kwa piritsi m'thupi.
