1. Chiyambi cha hydroxyethyl methylcellulose
Hydroxyethyl Methyl Cellulose (HEMC)ndi ether ya cellulose yosungunuka m'madzi yopanda ionic yomwe imapangidwa kudzera mu zochita za mankhwala monga alkaline ndi etherification ya cellulose yachilengedwe. Ili ndi kukhuthala kwabwino, kusunga madzi, kupanga filimu, mafuta ndi zomangira ndipo imagwiritsidwa ntchito kwambiri mu zipangizo zomangira, zokutira, mankhwala, chakudya ndi zina. M'munda womanga, makamaka mu mortar youma ndi putty powder, HEMC imagwira ntchito yofunika kwambiri.
2. Udindo wokonza njira zogwirira ntchito
Sinthani magwiridwe antchito omanga
Pakati pa zipangizo zomangira, HEMC ili ndi mphamvu zabwino kwambiri zokhuthala ndipo imatha kupititsa patsogolo kukana kwa thixotropy ndi kutsika kwa zinthu. Izi zimapangitsa kuti zomangamanga zikhale zosavuta. Makamaka mukamagwiritsa ntchito pamalo oyima, zinthuzo sizivuta kugwa, zomwe zimapangitsa kuti ogwiritsa ntchito apange chophimba chofanana komanso kukonza bwino ntchito yomanga.
Rial ikhoza kukhala yoyenera kwa nthawi yayitali itatha kupakidwa utoto kapena kusonkhezeredwa. Izi zimapatsa ogwira ntchito yomanga nthawi yochulukirapo yokonza ndi kukonza ndikukweza ubwino wa zomangamanga.
3. Udindo wowongolera magwiridwe antchito
Malo abwino kwambiri osungira madzi
Chimodzi mwa zinthu zodziwika bwino za HEMC ndi kusunga bwino madzi. Mu matope okhala ndi simenti kapena gypsum, HEMC imatha kuchepetsa kutaya madzi ndikuwonetsetsa kuti simenti kapena gypsum ili ndi chinyezi chokwanira panthawi ya hydration. Izi sizimangowonjezera mphamvu ndi mgwirizano wa zinthuzo, komanso zimachepetsa chiopsezo cha ming'alu ndi mabowo.
Limbikitsani kumatirira
Popeza HEMC ili ndi mphamvu zabwino zopangira filimu, imatha kupanga filimu yofanana pamalo omangira, motero imathandizira kumamatira pakati pa zinthuzo ndi pansi pake. Katunduyu ndi wofunikira kwambiri pakugwiritsa ntchito monga zomatira za matailosi ndi ma putty, komwe kumatha kusintha kwambiri kulimba ndi kukhazikika.
Sinthani kukana kuzizira ndi kusungunuka
M'malo ozizira kwambiri, kukana kuzizira ndi kusungunuka kwa zinthu ndikofunikira kwambiri. HEMC imawongolera kukana kwa zinthuzo nyengo mwa kukonza kufalikira kwa chinyezi mkati mwa zinthuzo ndikuchepetsa kusintha kwa kuchuluka komwe kumachitika chifukwa cha kuzizira ndi kusungunuka kwa madzi panthawi ya kuzizira ndi kusungunuka.
4. Zochitika zachizolowezi pakugwiritsa ntchito
matope ouma
Mu matope ouma, HEMC sikuti imangothandiza kusunga madzi ndi kugwira ntchito bwino kwa matopewo, komanso imawongolera kugwira ntchito bwino kwa zinthuzo, zomwe zimapangitsa kuti matopewo azifalikira mosavuta komanso kuoneka bwino panthawi yomanga.
Guluu wa matailosi
HEMC ikhoza kupititsa patsogolo mphamvu yolumikizirana ya colloid mu zomatira za matailosi a ceramic, kuonetsetsa kuti pali kulumikizana kolimba pakati pa matailosi a ceramic ndi substrates, ndikuchepetsa kutsetsereka kwa zinthu panthawi yomanga.
Ufa wa putty
Pakati pa ufa wa putty, HEMC imatha kukonza kusalala kwa pamwamba, kukonza kukana madzi ndi kukana ming'alu ya utoto, ndikupangitsa kuti wosanjikiza wa putty ugwire bwino ntchito yomanga pambuyo pake (monga utoto wa latex).
Hydroxyethyl methylcellulose yakhala chinthu chofunikira kwambiri komanso chofunikira kwambiri pa zipangizo zamakono zomangira chifukwa cha kukhuthala kwake, kusunga madzi, mafuta ndi zina. Sikuti imangowonjezera kuthekera kwa zinthu kukonzedwa, komanso imapangitsa kuti zinthu zomalizidwa zigwire bwino ntchito komanso kulimba, zomwe zimapangitsa kuti ogwira ntchito yomanga ndi ogwiritsa ntchito azikhala osavuta kugwiritsa ntchito komanso opindulitsa. Ndi kupita patsogolo kwa ukadaulo kosalekeza, minda yogwiritsira ntchito ndi zotsatira za HEMC zidzakulitsidwa, zomwe zipereka thandizo lochulukirapo pakukula kwa makampani omanga.
