1. Chiyambi cha hydroxyethyl methylcellulose
Hydroxyethyl Methyl Cellulose (HEMC)ndi non-ayoni m'madzi sungunuka mapadi etere opangidwa kudzera zochita za mankhwala monga alkalinization ndi etherification wa cellulose zachilengedwe. Ili ndi kukhuthala bwino kwambiri, kusungirako madzi, kupanga mafilimu, kudzoza ndi kulumikiza katundu ndipo imagwiritsidwa ntchito kwambiri pomanga, zokutira, mankhwala, chakudya ndi zina. M'munda womanga, makamaka mumatope owuma ndi putty powder, HEMC imagwira ntchito yofunika kwambiri.
2. Udindo wokonza processability
Limbikitsani ntchito yomanga
Pakati pa zomangira, HEMC ali kwambiri thickening katundu ndi bwino kusintha thixotropy ndi sag kukana zipangizo. Izi zimapangitsa kuti zomangamanga zikhale zosavuta. Makamaka mukamagwiritsa ntchito pamalo oyima, zinthuzo sizosavuta kugwa, zomwe zimapangitsa kuti ogwira ntchito azitha kupanga zokutira zofananira ndikuwongolera ntchito yomanga.
rial ikhoza kukhala yoyenera kwa nthawi yayitali itakutidwa kapena kugwedezeka. Izi zimagulira ogwira ntchito yomanga nthawi yochulukirapo kuti asinthe ndi kukonza komanso kupititsa patsogolo luso la zomangamanga.
3. Ntchito yopititsa patsogolo ntchito
Zabwino posungira madzi katundu
Chimodzi mwazinthu zodziwika bwino za HEMC ndikusunga bwino madzi. M'matope opangidwa ndi simenti kapena gypsum, HEMC ikhoza kuchepetsa kutayika kwa madzi ndikuonetsetsa kuti simenti kapena gypsum ili ndi chinyezi chokwanira panthawi ya hydration reaction. Izi sizimangowonjezera mphamvu ndi kugwirizana kwa zinthuzo, komanso zimachepetsa chiopsezo cha ming'alu ndi kuphulika.
Wonjezerani kumamatira
Popeza HEMC ili ndi zinthu zabwino zopanga mafilimu, imatha kupanga filimu yofananira pamalo omanga, potero imathandizira kumamatira pakati pa zinthu ndi gawo lapansi. Katunduyu ndi wofunikira kwambiri pakugwiritsa ntchito monga zomatira matailosi ndi ma putty, pomwe zimatha kupititsa patsogolo kukhazikika komanso kukhazikika.
Limbikitsani kukana kuzizira
M'madera ozizira kwambiri, kukana kwa kuzizira kwazinthu ndizofunikira kwambiri. HEMC imathandizira kukana kwanyengo kwa zinthuzo pokwaniritsa kugawa chinyezi mkati mwazinthu ndikuchepetsa kusintha kwa voliyumu komwe kumachitika chifukwa cha kuzizira ndi kusungunuka kwa madzi panthawi yachisanu.
4. Zochitika zofananira m'machitidwe ogwiritsira ntchito
dothi louma
Mumatope owuma, HEMC sikuti imangowonjezera kusungirako madzi ndi kugwiritsira ntchito matope, komanso imapangitsa kuti zinthuzo zitheke, zomwe zimapangitsa kuti matope azikhala osavuta kufalikira komanso mawonekedwe panthawi yomanga.
Guluu wa matailosi
HEMC ikhoza kupititsa patsogolo mphamvu yomangira ya colloid mu zomatira matailosi a ceramic, kuonetsetsa kulumikizana kolimba pakati pa matailosi a ceramic ndi magawo, ndikuchepetsa kutsetsereka kwa zinthu pakumanga.
Putty ufa
Pakati pa ma putty powders, HEMC imatha kuwongolera kusalala kwa pamwamba, kumapangitsa kuti madzi asasunthike komanso kutsekeka kwa zokutira, ndikupanga wosanjikiza wa putty kuchita bwino pakumanga kotsatira (monga utoto wa latex).
Hydroxyethyl methylcellulose yakhala chowonjezera chofunikira komanso chofunikira pazomangira zamakono chifukwa chakukhuthala kwake, kusunga madzi, kuthira mafuta ndi zina. Sikuti zimangopangitsa kuti zinthu zitheke, komanso zimathandizira magwiridwe antchito komanso kulimba kwa zinthu zomalizidwa, kubweretsa kumasuka komanso phindu lalikulu kwa ogwira ntchito yomanga ndi ogwiritsa ntchito. Ndi kupita patsogolo kosalekeza kwaukadaulo, magawo ogwiritsira ntchito ndi zotsatira za HEMC zidzakulitsidwanso, ndikupereka chithandizo chochulukirapo pakukula kwa ntchito yomanga.
