HPMC ndi HEMC muzomangamanga

HPMC (Hydroxypropyl Methyl Cellulose) ndi HEMC (Hydroxy Ethyl Methyl Cellulose) ndi ma cellulose ether omwe amagwiritsidwa ntchito kwambiri pomanga zinthu chifukwa cha zinthu zawo zapadera.Ndi ma polima osungunuka m'madzi opangidwa kuchokera ku cellulose, polima wachilengedwe wopezeka m'makoma a cellulose.HPMC ndi HEMC amagwiritsidwa ntchito ngati zowonjezera pazomangamanga zosiyanasiyana kuti apititse patsogolo katundu wawo ndikuwongolera magwiridwe antchito.

Zotsatirazi ndi zina za HPMC ndi HEMC pazomangamanga:

Zomatira za matailosi: HPMC ndi HEMC nthawi zambiri zimawonjezeredwa ku zomatira za matailosi kuti ziwongolere magwiridwe antchito komanso mphamvu zomangira.Ma polima awa amakhala ngati zokhuthala, kupereka nthawi yotseguka bwino (utali womatira umakhalabe wogwiritsidwa ntchito) komanso kuchepetsa kugwa kwa matailosi.Zimapangitsanso zomatira kumamatira ku magawo osiyanasiyana.

Mitondo Ya Cementitious: HPMC ndi HEMC amagwiritsidwa ntchito mumatope a simenti monga pulasitala, pulasitala ndi makina omaliza otsekera kunja (EIFS).Ma polima awa amathandizira kuti matope azitha kugwira ntchito, kupangitsa kuti ikhale yosavuta kufalikira ndikuyika.Zimapangitsanso mgwirizano, kuchepetsa kuyamwa kwa madzi komanso kumamatira matope kumagulu osiyanasiyana.

Zopangidwa ndi Gypsum: HPMC ndi HEMC zimagwiritsidwa ntchito popanga gypsum monga gypsum plasters, joint compounds and self-leveling underlayings.Amakhala ngati othandizira kusunga madzi, kuwongolera magwiridwe antchito ndikutalikitsa nthawi yoyika zinthu.Ma polima awa amathandiziranso kukana kwa ming'alu, kuchepetsa kuchepa komanso kumamatira.

Ma Compounds Odziyimira pawokha: HPMC ndi HEMC amawonjezedwa kuzinthu zodzipangira okha kuti apititse patsogolo kuyenda ndi kusanja katundu.Ma polima awa amathandizira kuchepetsa kukhuthala, kuwongolera mayamwidwe amadzi ndikupereka kutha kwapamwamba.Zimathandizanso kumamatira kwapawiri ku gawo lapansi.

Grouting: HPMC ndi HEMC zitha kugwiritsidwa ntchito popangira malo olumikizira matailosi ndi zomangamanga.Amakhala ngati ma rheology modifiers, kuwongolera kuyenda komanso kugwira ntchito kwa ma grouts.Ma polima amenewa amachepetsanso kulowa kwa madzi, kumapangitsa kuti azimatira komanso kumapangitsa kuti zisawonongeke.

Ponseponse, HPMC ndi HEMC zimagwiritsidwa ntchito kwambiri pazomangamanga chifukwa cha kuthekera kwawo kupititsa patsogolo kusinthika, kumamatira, kusunga madzi, komanso magwiridwe antchito onse azinthu.Amalimbikitsa njira zomangira zabwinoko popititsa patsogolo kulimba ndi mtundu wazinthu zosiyanasiyana zomanga.
