Kodi MHEC ndi chiyani? Udindo Wofunika Kwambiri mu Mafomula a Mortar ndi Utoto

Pamene makampani omanga ndi opaka utoto akupitilizabe kusintha, kufunikira kwa zowonjezera zapamwamba zomwe zimakweza ubwino wa malonda, kugwiritsa ntchito bwino, komanso kulimba kwakula kwambiri. Pakati pa zowonjezera izi,Methyl Hydroxyethyl Cellulose (MHEC)lakhala limodzi mwa ma ether ofunikira kwambiri a cellulose omwe amagwiritsidwa ntchito mu mortars osakaniza ndi madzi, zomatira za matailosi, putty wall, zinthu zopangidwa ndi gypsum, ndi utoto wochokera m'madzi.

MHEC imayamikiridwa chifukwa cha kusunga bwino madzi, kukhuthala, kukulitsa magwiridwe antchito, komanso kuwongolera rheology. Imathandiza opanga kupanga zipangizo zomangira ndi zokutira zomwe zimakwaniritsa miyezo yofunikira kwambiri yogwirira ntchito komanso kukonza mawonekedwe a ntchito kwa makontrakitala ndi ogwiritsa ntchito kumapeto.

Nkhaniyi ikufotokoza za MHEC, momwe imapangidwira, makhalidwe ake ofunikira, ndi chifukwa chake imagwira ntchito yofunika kwambiri pakupanga matope ndi utoto wamakono.

Kumvetsetsa MHEC

Kodi MHEC ndi chiyani?

Methyl Hydroxyethyl Cellulose (MHEC) ndi ether ya cellulose yosakhala ionic yochokera ku cellulose yachilengedwe, yomwe nthawi zambiri imapezeka kuchokera ku thonje loyengedwa bwino kapena zamkati zamatabwa.

Kudzera mu njira yolamulidwa ya etherification, cellulose imasinthidwa ndi mankhwala poyambitsa:

  • Magulu a Methyl
  • Magulu a Hydroxyethyl

Zosinthazi zimasintha cellulose yosasungunuka kukhala polima yosungunuka m'madzi yokhala ndi mphamvu zabwino kwambiri zokhuthala komanso zosungira madzi.

 

MHEC ndi ya banja lomwelo monga:

Pakati pa ma cellulose ethers awa, MHEC ndi yotchuka kwambiri pa ntchito zomanga chifukwa cha kusunga bwino madzi komanso kugwirizana bwino ndi simenti ndi makina a gypsum.

Kapangidwe ka Mankhwala a MHEC

Msana wa cellulose uli ndi mayunitsi obwerezabwereza a anhydroglucose.

Panthawi yopanga:

  • Magulu ena a hydroxyl amalowedwa m'malo ndi magulu a methyl.
  • Magulu ena a hydroxyl amalowedwa m'malo ndi magulu a hydroxyethyl.

Kusintha kumeneku kumapereka:

  • Kusungunuka bwino kwa madzi
  • Kukhazikika kwa kutentha
  • Kuchita bwino kwa makulidwe
  • Kugwira ntchito bwino kwambiri

Mlingo wa kusintha kwa chinthucho umadalira kwambiri momwe zinthuzo zimagwirira ntchito komanso momwe zimagwiritsidwira ntchito.

Njira Yopangira MHEC

Gawo 1: Kukonzekera kwa Cellulose

Maselo oyeretsedwa ochokera ku thonje kapena matabwa amasankhidwa ndikukonzedwa bwino.

Gawo 2: Kusakaniza kwa Alkalization

Cellulose imachiritsidwa ndi sodium hydroxide kuti iyambe kugwira ntchito.

Gawo 3: Kukonza Ether

Cellulose yogwiritsidwa ntchito imachitapo kanthu ndi:

  • Methyl chloride
  • Ethylene okusayidi

Izi zimayambitsa magulu a methyl ndi hydroxyethyl mu kapangidwe ka mamolekyu.

Gawo 4: Kusalowererapo

Alkali wochulukirapo amachotsedwa.

Gawo 5: Kutsuka ndi Kuyeretsa

Zodetsa ndi mankhwala otsala zimachotsedwa.

Gawo 6: Kuumitsa ndi Kupera

Chotsukidwacho chimaumitsidwa ndikuphwanyidwa kukhala ufa wabwino kwambiri woyenera kugwiritsidwa ntchito m'mafakitale.

Katundu Waukulu wa MHEC

Kusunga Madzi Kwabwino Kwambiri

Chimodzi mwa zinthu zofunika kwambiri za MHEC ndi kuthekera kwake kusunga madzi mkati mwa makina opangidwa ndi simenti.

Ubwino wake ndi monga:

  • Kusungunuka bwino kwa simenti
  • Kukula kwa mphamvu zowonjezeka
  • Kuchepa kwa ming'alu
  • Nthawi yotsegulira yayitali

Kukhuthala kwa Mphamvu

MHEC imawonjezera kukhuthala kwa minofu ndipo imapereka mphamvu zokhazikika za rheological.

Izi zimathandiza:

  • Pewani kusiyanitsa
  • Sinthani kusinthasintha
  • Sinthani makhalidwe a ntchito

Kukonza Kugwira Ntchito

MHEC imapanga mawonekedwe osalala komanso okoma a matope omwe ndi osavuta kugwiritsa ntchito.

Ubwino wake ndi monga:

  • Kuchepa kwa ntchito
  • Kuchita bwino kwa troweling
  • Kumaliza bwino kwa pamwamba

Kupanga Mafilimu

MHEC imathandizira kupanga mafilimu oteteza omwe amawongolera magwiridwe antchito a kupaka utoto.

Kukhazikika

Mayankho a MHEC amakhalabe okhazikika pansi pa kutentha kosiyanasiyana ndi pH.

Chifukwa Chake MHEC Ndi Yofunika Mu Mafomula a Mortar

Ma matope amakono osakanikirana ndi madzi amafunikira makhalidwe enieni a ntchito.

MHEC imathandiza kukwaniritsa zolinga izi.

MHEC mu Zomatira za Matailosi

Ma glue a matailosi ndi ena mwa magawo akuluakulu ogwiritsira ntchito MHEC.

Kusunga Madzi

MHEC imaletsa kutayika kwa madzi mwachangu m'njira ziwiri:

  • Konkire
  • Mabodi a simenti
  • Malo opangidwa ndi miyala

Izi zimatsimikizira kuti simenti imalowa bwino.

Kutsegulira Nthawi Yowonjezera

Okhazikitsa amapeza nthawi yochulukirapo yoyika matailosi.

Ubwino wake ndi monga:

  • Kukonza matailosi bwino
  • Kuchepetsa zinyalala
  • Ubwino wokhazikitsa bwino

Kukonza Kumatira

MHEC imalimbikitsa mgwirizano wamphamvu pakati pa:

  • Guluu wa matailosi
  • Malo oimika matailosi
  • Pansi pa nthaka

Kugwira Ntchito Kotsutsana ndi Kusakhazikika

Pakugwiritsa ntchito matailosi a pakhoma, MHEC imawongolera kukana kutsetsereka.

Matailosi amakhalabe pamalo abwino akayikidwa.

MHEC mu Wall Putty

Putty ya pakhoma imafuna kusalala bwino komanso kusinthasintha.

MHEC imapereka:

  • Kufalitsa kosavuta
  • Kusunga bwino madzi
  • Makhalidwe abwino odulira mchenga
  • Kukana ming'alu
  • Kulimbitsa kumamatira

Zotsatira zake, malo amakhala osalala komanso olimba.
