HPMC mu Construction

Hydroxypropyl methyl cellulose HPMC ndi cellulose yachilengedwe ya polima ngati zopangira, kudzera mumndandanda wamankhwala opangidwa ndi osakhala ionic cellulose ether. Ndiwopanda fungo, wosakoma, wopanda poizoni wa ufa woyera womwe umatuluka mumtsuko wowoneka bwino kapena wamtambo pang'ono m'madzi ozizira. Ndi thickening, adhesion, kubalalitsidwa, emulsification, filimu mapangidwe, kuyimitsidwa, adsorption, gel osakaniza, pamwamba ntchito, posungira chinyezi ndi colloidal chitetezo, etc. Hydroxypropyl methyl cellulose HPMC, methyl cellulose MC angagwiritsidwe ntchito pomanga zipangizo, ❖ kuyanika makampani, kupanga utomoni, mafakitale a ceramic, mankhwala, chakudya, nsalu, ulimi, mankhwala a tsiku ndi tsiku ndi mafakitale ena.

Chemical equation:
[C6H7O2(OH) 3-MN (OCH3) M (OCH2CH(OH)CH3) N] X

Makhalidwe a HPMC omwe amagwiritsidwa ntchito pomanga
1. Kusunga madzi
Hydroxypropyl methyl cellulose HPMC yomanga imalepheretsa kuyamwa kwamadzi kwambiri ndi gawo lapansi, ndipo madzi amayenera kusungidwa mu pulasitala momwe angathere pomaliza kulimba kwa gypsum. Katunduyu amadziwika kuti kusungirako madzi, ndipo amafanana ndi kukhuthala kwa nyumba yeniyeni ya hydroxypropyl methyl cellulose HPMC mu stucco, kukwezera kukhuthala kwa yankho, kumapangitsa kuti madzi asungidwe.
Madziwo akangochulukirachulukira, mphamvu yosungira madzi imachepa, chifukwa madzi ochulukirapo adachepetsa kupanga njira ya hydroxypropyl methyl cellulose HPMC, zomwe zimapangitsa kuchepa kwa mamasukidwe akayendedwe.
2. Sag resistance
Chipilala chomwe chimalimbana ndi kutuluka ndi kupachikidwa chimalola womangayo kugwiritsa ntchito zokutira wandiweyani popanda kusuntha, zomwe zikutanthauza kuti stucco yokha ndi thixotropic, mwinamwake imatsika pansi pomanga.
3. Chepetsani kukhuthala, kumanga kosavuta
Powonjezerapo mitundu ingapo yomanga yapadera ya hydroxypropyl methyl cellulose HPMC mankhwala, kukhuthala otsika komanso kumangidwe kosavuta kungapezeke kuchokera ku pulasitala ya gypsum, pogwiritsa ntchito nyumba yocheperako yodzipereka ya hydroxypropyl methyl cellulose HPMC, kukhuthala pang'ono komanso zomangamanga zosavuta, komabe, nyumba yocheperako hydroxypropyl methyl cellulose HPMC yosungira madzi ndi yofooka, imayenera kukweza kuchuluka kwake.
4. Mphamvu ya kukula kwa stuko
Pamtengo wokhazikika wa matope owuma, zimakhala zotsika mtengo kupanga voliyumu yonyowa yamatope, yomwe imatha kutheka powonjezera madzi ndi thovu. Koma madzi ochuluka ndi thovu amatha kuwononga mphamvu.

Kugwiritsa ntchito kwa HPMC muzomangamanga:
1. Ceramic matailosi zomatira
(1) Ndikosavuta kuumitsa zosakaniza zosakaniza, sizingapange zopanga, kuwongolera liwiro la ntchito, kukonza ntchito yomanga, kupulumutsa nthawi yogwira ntchito, kuchepetsa mtengo wantchito.
(2) Potalikitsa nthawi yotsegulira, sinthani magwiridwe antchito a matailosi, ndikupereka zomatira zabwino kwambiri.

2. pulasitala yopangidwa ndi simenti
(1) Kupititsa patsogolo kufanana, kupanga matope kukhala osavuta kupaka utoto, nthawi yomweyo kusintha anti-kupachikidwa, kuwonjezera madzimadzi ndi kupopera, kupititsa patsogolo ntchito.
(2) Kusungidwa kwamadzi kwakukulu, kutalikitsa nthawi yoyika matope, kuwongolera magwiridwe antchito, kumathandizira kuti ma hydration ndi kulimba kwamatope apange mphamvu zamakina apamwamba.
(3) Kuwongolera kuyambitsa mpweya, kuti athetse ming'alu pamwamba pa zokutira, kupanga malo abwino osalala.

3. Gypsum base pulasitala ndi gypsum amapereka mankhwala
(1) Kupititsa patsogolo kufanana, kupanga matope kukhala osavuta kupaka utoto, nthawi yomweyo kusintha anti-kupachikidwa, kuwonjezera madzimadzi ndi kupopera, kupititsa patsogolo ntchito.
(2) Kusungidwa kwamadzi kwakukulu, kutalikitsa nthawi yoyika matope, kuwongolera magwiridwe antchito, kumathandizira kuti ma hydration ndi kulimba kwamatope apange mphamvu zamakina apamwamba.
(3) Kuwongolera kusasinthika kwa dothi lofanana, kupanga zokutira koyenera pamwamba.

4. Dongo la zomangamanga
(1) Limbikitsani mamasukidwe amiyala pamwamba, onjezerani kusunga madzi, onjezerani mphamvu ya matope.
(2) Kupititsa patsogolo lubricity ndi pulasitiki, kukonza zomangamanga; Mtondo wopangidwa ndi cellulose ether ndi wosavuta kupanga, umapulumutsa nthawi yomanga ndikuchepetsa mtengo womanga.
(3) cellulose ether, makamaka kusungirako madzi ochuluka, ndi koyenera ku njerwa zoyamwa madzi.

5. Plate joint filler
(1) Kusunga madzi kwabwino, kukulitsa nthawi yotsegulira, kukonza bwino ntchito. Mafuta okwera kwambiri, osavuta kusakaniza.
(2) Anti-shrinkage ndi anti-scracking properties zinakonzedwa bwino ndipo khalidwe lapamwamba la zokutira linasinthidwa.
(3) Sinthani kumamatira kwa malo omangika, kupereka mawonekedwe osalala, osalala.

6.Self kusanja pansi zipangizo
(1) kupereka mamasukidwe akayendedwe, angagwiritsidwe ntchito ngati odana ndi kuthetsa AIDS.
(2) Limbikitsani kupopa kwa madzi, konzani bwino pakukonza pansi.
(3) Kuwongolera kusungidwa kwa madzi ndi kuchepa, kuchepetsa kusweka ndi kutsika kwa nthaka.

7.Kupaka utoto wamadzi ndi zokutira
(1) Pewani mvula yolimba, onjezerani nthawi ya chidebe cha chinthucho.
(2) Kukhazikika kwachilengedwe kwachilengedwe komanso kuyanjana kwakukulu ndi zigawo zina.
(3) Sinthani madzimadzi, perekani anti-splash, anti-drop and flow resistance, onetsetsani kutha kwapamwamba kwambiri.

8.Wallpaper ufa
(1)kusungunuka mwachangu popanda zotupa, zomwe ndi zabwino kusakaniza.
(2) imapereka mphamvu yolumikizana kwambiri.

9.Extrusion akamaumba mbale simenti
(1) ali ndi cohesiveness mkulu ndi lubricity, kumapangitsanso processing ntchito extrusion mankhwala.
(2) Kupititsa patsogolo mphamvu zobiriwira, kulimbikitsa machiritso a hydration, onjezani zokolola zamafuta omalizidwa.

10.matope osakaniza
mu premixed matope posungira madzi ndi bwino kuposa mankhwala wamba, kuonetsetsa hydration zonse organic cementitious zipangizo, kwambiri kupewa kuyanika mofulumira kwambiri chifukwa cha kuchepa mphamvu chomangira, ndi kuyanika shrinkage chifukwa chosweka. HPMC ilinso ndi ena mpweya entraining tingati, premixed matope mankhwala apadera HPMC, mpweya entraining mlingo woyenera, yunifolomu ndi thovu yaing'ono, akhoza kusintha mphamvu ndi gloss wa premixed matope. Premixed matope mankhwala apadera a HPMC ali ndi pang'onopang'ono, amatha kutalikitsa nthawi yotsegulira matope osakanikirana, kuchepetsa zovuta zomanga.
