Udindo wa hydroxypyl methylcellulose (hpmc) mu gypsum puster ntchito

Chiyambi:

Gypsum Pulaster, zinthu zomanga zambiri zodziwika bwino zomwe zimadziwika bwino pakugwiritsa ntchito, zawona kupita patsogolo kwakukulu kwa zaka zaposachedwa ndikuphatikizidwa ndi zowonjezera monga hydroxygyulose (hpmc). HPMC, cellulose yochokera ku cellulose, imapereka zinthu zingapo zofunika zomwe zimathandizira kuchita ndi kugwira ntchito kwa gypsum puster. Nkhaniyi imakhudzanso gawo la HPMC mu gypsum puster, limapangitsa kuti mankhwala ake azikhala ndi mankhwala, mikhalidwe yogwira ntchito, komanso tanthauzo lenileni.

Mankhwala Opangidwa ndi Mankhwala a HPMC:

Hydroxypropyl ya methylcelulose imapangidwa kudzera mu mankhwala opatsirana mankhwala a cellulose, chifukwa chosungunulira madzi ndi polymer yosiyanasiyana. Kapangidwe kake kamakhala ndi ma celluurose ang'onoang'ono kumangiriza ndi methyl ndi hydroxypyl oyimira. Mulingo wa zolowetsa (DS) ya methyl ndi hydroxypyl amakhudza kwambiri katundu wa HPMC, kuphatikizapo mamasukidwe, madzi kususuka, komanso kuthekera kwa filimu. HPMC imawonetsa bwino kuchuluka kwa madzi, kupanga njira zokhazikika zomwe zimathandizira kuti zikhale zothandiza komanso zomatira mu gypsum pulasitiki yogwiritsa ntchito.

Ntchito za HPMC ku Gypsum Pulaster:

Kusunga kwamadzi: HPMC imagwira ngati polymer, ndikupanga filimu yoteteza kuzungulira gypsum, potero kupewa kutayika kwa madzi mwachangu panthawi yoyenera. Izi zimathandizira kugwiritsidwa ntchito kwa pulasitala, kulola kugwiritsa ntchito kosinthika ndikuchepetsa chiopsezo chosweka kapena shrinkage.

Kusintha kwa Rhelogy: kuphatikiza kwa HPMC kumathandizira kuti pakhale phokoso la gypsum, kupereka mawonekedwe a preeudoplastic kapena Sheeption. Izi zimapangitsa kuti pafalitsidwe bwino, kuchepa kusamba, komanso kuwonjezera thixotropic katundu, otsogolera kugwiritsidwa ntchito ndi kukwaniritsa ma yunifolomu kumaliza kumaliza.

Zotsatsa zotsatsa: hpmc imawonjezera cholumikizira cha pulasitala ya gypsum la pulasitala ya gypsum kupita ku pulasitala ya gypsum kupita ku piya magawo osiyanasiyana, kuphatikizapo zomangamanga, konkriti, komanso yopumira. Kupanga kwa mawonekedwe okhazikika pakati pa pulasitala ndi gawo lalikulu kumalimbikitsa kulimbikira ndikuchepetsa kuwonongeka kapena kuchepetsedwa, kuonetsetsa kukhazikika kwa nthawi yayitali komanso kukhazikika kwa umphumphu.

Kukhazikitsa Kulamulira: Mwa kukonza hydration kinetics ya gypsum, hpmc imathandizira kuwongolera nthawi ya makonzedwe a mapulogalamu a pulasitala. Izi zimapangitsa kuti pakhale zosintha zomwe zimagwiritsidwa ntchito pazofunikira pa pulogalamuyi, kuyambira nthawi yayitali kuti mupange ntchito zowoneka bwino nthawi yayitali kuti ikhale yodzikongoletsa kapena yokongoletsera.

Ubwino wa HPMC mu Gypsum Pulasiti:

Kuphatikizira kwa HPMC kumapereka zabwino zingapo kwa gypsum pusters

Kugwiritsa Ntchito Kugwira Ntchito: Kupititsa patsogolo madzi mosasunthika kumapangitsa kuti pulasitala yabwino kwambiri, yolimba kwambiri imasakaniza, yothandizira kugwiritsa ntchito ndikuchepetsa zinyalala.

Kulimbikitsidwa Kukhazikika: Kumatira Kwapamwamba Kwambiri ndi kukhazikitsa ulamuliro kumathandizira kukulitsa mphamvu yaubwenzi, kuchepetsedwa kusokonekera, komanso kukana kwa zinthu zachilengedwe monga chinyezi.

Mapulogalamu osintha: Mapepala osinthika a HPMC

Kulingalira ndi malangizo ogwiritsira ntchito:

Mukamapanga hpmc mu gypsum plaster ma proster, zinthu zingapo ziyenera kuganiziridwa kuti zitheke ndikuwonetsetsa kuti kuyesedwa:

Kusankha kwa HPMC Gawo: Kusankha kwa kalasi ya HPMC kuyenera kukhazikitsidwa pazofunikira zapadera, poganizira zinthu za akaunti monga mafayilo, kusungidwa kwamadzi, ndikukhazikitsa ulamuliro.

Kuyesa kwa Kugwirizana: Kuyesa kwa HPMC ndi zina zowonjezera kapena zotsatsira ndikofunikira kuti mupewe njira ndikuwonetsetsa kuti ntchito yopanga pulasitala.

Njira Zosakanikirana: Njira zosakanikirana zoyenera, kuphatikizapo kusakanikirana kosinthana kwa HPMC ndipo kumapangitsa kuwunika kwapadera, kuphatikizapo kuwunika kwa pulasitiki, ndikofunikira kuwunikirana ndi kutsatira miyezo yogwiritsira ntchito.

Hydroxypylpyl (hpmc) amasewera gawo lothandizirana ndi ntchito, kugwirira ntchito, ndi kulimba kwa gypsum plaster ma curter. Kudzera pamitundu yake yapadera yamadzi, kusinthasintha kwa Rheollogy, kupititsa patsogolo kuwongolera, hpmc kumathandizira pakusinthana kwa pulasitala ndi kudalirika kwa Plaster Pulati Yomanga. Mwa kumvetsetsa ntchito ndi mapindu a HPMC, akatswiri amatha kupeza mapulaneti kuti akwaniritse zofuna za ntchito zamakono ndikukwaniritsa miyezo yapamwamba komanso yogwiritsira ntchito.
