M'zaka zaposachedwa, zokutira zamadzi zatchuka kwambiri chifukwa cha kutetezedwa kwawo kwa chilengedwe, zoopsa zochepa, komanso zomanga zovuta. Kuti mupititse patsogolo magwiridwe ake ndi mawonekedwe a zokutira izi, zowonjezera zosiyanasiyana zimagwiritsidwa ntchito, imodzi mwazowonjezera zowonjezera ndi hydroxypropyl no methycellulose (hpmc). Ether iyi ya Ether imagwira ntchito yofunika kwambiri posintha mafayilo, kukhazikika, zomatira ndi mawonekedwe onse ovala zamadzi
Phunzirani za HPMC
Hydroxypropylmethyllulose Kudzera mu kusintha kwamankhwala, cellulose imasinthidwa kukhala HPMC, ndikupanga mtengo wosungunulira madzi wokhala ndi mapulogalamu osiyanasiyana. HPMC imadziwika ndi kuphatikiza kwake kwapadera kwa hydrophobic methyl ndi hydrophilic hydroxypyl magulu, kulola kuti musinthe zolimbitsa thupi zam'madzi.
Magwiridwe antchito a HPMC pakubala kwa madzi
Kuwongolera Visccence:
HPMC imadziwika kwambiri chifukwa chokhoza kuwongolera mafayilo ophimbidwa madzi. Posintha kuchuluka kwa hpmc, opanga amatha kukwaniritsa makulidwe kapena kuwonda, chifukwa chogwiritsa ntchito bwino.
Kukhazikika ndi kukana kwa Aleg:
Kuphatikiza kwa HPMC kumathandizira kukhazikika kwa fomu yolumikizira madzi ndipo imalepheretsa kusaka kapena kukhetsa pakumanga. Izi ndizofunikira kwambiri pamiyendo yomwe imasungabe ngakhale yophimba kwambiri ndizovuta.
Sinthani Mode:
HPMC imathandizira kukulitsa zomatira ku mitundu yosiyanasiyana yakumaliza, yokhazikika. Izi ndizofunikira kwambiri kuti zojambula zakunja zomwe zimadziwika ndi nyengo yosiyanasiyana nyengo.
Kusunga kwamadzi:
HPMC imadziwika chifukwa chosunga madzi, zomwe zimakhala zopindulitsa popewa kuyanika kwa utoto pa ntchito. Izi zimatsimikizira kuti ngakhale kumalizako.
Thixotropy:
Chilengedwe cha hixotropic cha HPMC chimalola utoto kuti ugwiritsidwe ntchito mosavuta ndi kuyesetsa kochepa mukamakhalabe osasinthika mukakhala osayenda. Izi ndizofunikira kwambiri kuchepetsa zokolola panthawi yogwiritsa ntchito.
Kugwiritsa ntchito HPMC pakubala kwa madzi
Mkati ndi kunja:
HPMC imagwiritsidwa ntchito kwambiri mkati mwanyumba yopanda madzi ndikusintha magwiridwe awo onse. Zimathandiza kuti tipeze yosalala, ngakhale kumaliza kwinaku ndikumadzitchinjiriza ku zinthu zachilengedwe.
Utoto Wopanga:
Zovala Zojambula, zomwe nthawi zambiri zimagwiritsidwa ntchito pokongoletsa, kupindula ndi ulamuliro wa rheology zoperekedwa ndi HPMC. Zimathandizira kusunga mawonekedwe ndi mawonekedwe omwe akufuna.
Primer ndi Sealer:
Mu primers ndi zigawo za zigawo, pomwe zomatira ndi gawo lalikulu zikuchititsa kuti HPMC imathandizira kukonza zotsatsa komanso zomwe zimapangitsa kuti pakhale ntchito.
Masonry ndi Zovala za Stucco:
HPMC imatha kugwiritsidwa ntchito kwa omanga ndi zokutira, kupereka mawonekedwe ofunikira ndi mitundu ya sag-sag yofunikira ndi zokutira zapaderazi.
Zovala zamatabwa:
Zophatikiza zamadzi zimapindula ndi kuthekera kwa HPMC yopititsa patsogolo zomatira ndikupewa kusaka, ndikuwonetsetsa kuti mathala ndi mitengo.
Ubwino wogwiritsa ntchito HPMC pakubala kwa madzi
Zosangalatsa Zachilengedwe:
HPMC imachokera ku zinthu zokonzanso ndipo zimathandizira kuti chilengedwe cha chilengedwe chazovala zamadzi. Kusintha kwake kochulukirapo kumawonjezera kukhazikika kwa mafilimu.
Makina otukuka:
Kuwongolera kwa rheology komwe kumaperekedwa ndi HPMC kumapangitsa kuti zikhale zosavuta kuzigwiritsa ntchito, kaya ndi burashi, wodzigudubuza kapena kutsitsa, kulimbikitsa bwino ndi kugwiritsa ntchito bwino.
Kupititsa patsogolo Kukhazikika:
HPMC imasintha zomatira komanso kukhazikika, kuthandiza kukulitsa kulimba komanso kutayikira kwa utoto wamadzi kumatha, kuchepetsa kufunika kowunikira pafupipafupi.
Kusiyanitsa:
HPMC ndi zowonjezera zosiyanasiyana zomwe zingagwiritsidwe ntchito m'njira zosiyanasiyana zokutira zamadzi kuti zigwirizane ndi njira zingapo ndi njira zogwiritsira ntchito.
Ntchito yayikulu:
Kukula kwamphamvu kwa HPMC ndikukhazikika kumathandizira kuchepetsa kuchuluka kwa utoto ndi zowonjezera zina zokwera mtengo zofunika pakupanga mafinya, zomwe zimagwiritsidwa ntchito pazonse.
Pomaliza
Hydroxypropymethylcellulose (hpmc) ndiowonjezera owonjezera mumidzi. Zosiyanasiyana zake zapadera, kuphatikizapo kukhazikika kwa mafayilo, zokhazikika, zomatira bwino komanso zachilengedwe zachilengedwe, zimapangitsa kukhala chinthu chofunikira kwambiri pakupanga zokutira zapamwamba, zachilengedwe zachilengedwe. Monga momwe zimafunira zinthu zokhazikika komanso zothandizira kusuta zimapitilirabe ndi msika wophatikiza, hpmc zimatsalira pakupanga kwamadzi komwe kumakumana ndi miyezo yachilengedwe.
