Opanga HPMC - zotsatira za HPMC pa zinthu za gypsum

dziwitsani

Zogulitsa za Gypsum zimagwiritsidwa ntchito kwambiri pantchito yomanga chifukwa chazomwe zimawotcha moto, zotsekemera zomveka komanso zotsekemera zotentha. Komabe, mankhwala a gypsum okha sangathe kukwaniritsa zofunikira zonse zamakono zamakono. Chifukwa chake, zosintha monga hydroxypropyl methylcellulose (HPMC) zimawonjezedwa kuzinthu za gypsum kuti ziwongolere magwiridwe antchito, mphamvu, kusunga madzi komanso kulimba. M'nkhaniyi, tikambirana zotsatira za HPMC pa zinthu za gypsum.

Limbikitsani ntchito

HPMC nthawi zambiri ntchito monga thickener kapena defoamer kusintha workability gypsum mankhwala. Kuphatikizika kwa HPMC kumatha kukonza makina azinthu za gypsum, kupititsa patsogolo magwiridwe antchito, motero kupeza ntchito yomanga bwino. Kuphatikiza apo, HPMC imatha kukulitsa kukana kwa zinthu za gypsum, kuwonetsetsa kuti zinthuzo sizidzawonongeka kapena kugwa panthawi yomanga.

Konzani kasungidwe ka madzi

Pamene zinthu za gypsum zimasakanizidwa ndi madzi, zimakhala zowuma mofulumira, zomwe zimakhudza njira yochiritsira komanso khalidwe lomaliza la mankhwala. Pofuna kukonza kusungirako madzi kwa zinthu za gypsum, HPMC imawonjezedwa ngati chomangira. HPMC imapanga filimu yopyapyala pamwamba pa gypsum, yomwe imatha kusunga chinyezi mu mankhwala, kulimbikitsa ndondomeko ya hydration, ndikuwonjezera mphamvu ya mankhwala omaliza.

onjezerani mphamvu

Kuwonjezera HPMC akhoza kwambiri kusintha mphamvu za gypsum mankhwala. HPMC imapanga filimu yopyapyala pamwamba pa gypsum particles, yomwe imatha kudzaza mipata pakati pa tinthu tating'onoting'ono ndi kulimbikitsa mapangidwe a mankhwala. Kanemayo amawonjezeranso mphamvu yolumikizirana pakati pa tinthu tating'ono ta gypsum, zomwe zimapangitsa kuti pakhale chinthu chokhala ndi mphamvu zopondereza, mphamvu zosinthika komanso kukana.

bwino durability

Kukhazikika kwa chinthu cha gypsum ndikofunikira kwambiri pakugwira ntchito kwake, makamaka m'malo okhala ndi chinyezi chambiri kapena kutengera madzi. Kugwiritsa ntchito HPMC kumatha kukulitsa kulimba kwa zinthu za gypsum popanga zosanjikiza zodzitchinjiriza pamwamba pa chinthucho, kuteteza kulowa kwa chinyezi ndikuwongolera kukana kwanyengo ndi ukalamba. HPMC amachepetsanso mwayi wosweka ndi kuchepetsa chiopsezo cha delamination.

kuchepetsa kuchepa

Zogulitsa za Gypsum zimakonda kuchepa panthawi yakuchiritsa, zomwe zingayambitse ming'alu ndi kuwonongeka kwa mankhwala. Powonjezera HPMC ku zinthu za gypsum, kuchepa kwa mankhwalawa kumatha kuchepetsedwa kwambiri, kupangitsa kuti chomalizacho chikhale chosavuta komanso chokhazikika. Kuphatikiza apo, imatha kuchepetsa kuchitika kwa zolakwika zamapangidwe.

Pomaliza

Mwachidule, kugwiritsa ntchito hydroxypropylmethylcellulose (HPMC) monga chosinthira muzinthu za gypsum kumatha kupititsa patsogolo magwiridwe antchito awo, mphamvu, kusunga madzi komanso kukhazikika. HPMC ndi chowonjezera kwambiri kuti sikuti kumangowonjezera katundu mawotchi gypsum mankhwala, komanso kumathandiza kutalikitsa moyo wawo utumiki ndi kuchepetsa chiopsezo warping kapena akulimbana. Choncho, ndi chinthu chofunika kwambiri pa ntchito yomanga ndipo ntchito yake ikuwonjezeka.
