Kusungirako madzi: HPMC imawonjezera kusungidwa kwa madzi kwa osakaniza, kulola kuti zinthuzo zikhalebe zogwiritsidwa ntchito kwa nthawi yayitali. Izi ndizothandiza makamaka pantchito zomanga pomwe nthawi yayitali yogwirira ntchito ikufunika.

Kugwira ntchito: HPMC imathandizira kugwira ntchito kwa kusakaniza, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito ndikufalikira mozungulira. Zimathandizira kukwaniritsa zosalala komanso zomaliza.

Kumamatira: HPMC imathandizira kumamatira kwa khoma la putty, stucco kapena zokutira pamwamba pa gawo lapansi, kuonetsetsa kuti pali mgwirizano wabwinoko komanso kuchepetsa mwayi wosweka kapena kusenda.

Kukaniza kwa Sag: HPMC imathandizira kuchepetsa kugwa kapena kugwa kwazinthu pazoyima kapena zapamwamba. Amapereka katundu wa thixotropic, kulola kuti chisakanizocho chigwire mawonekedwe ake ndikukhalapo.

Kukaniza kwa Crack: Powonjezera HPMC, zokutira komaliza zikuwonetsa kulimba kwa ming'alu chifukwa cha kusinthasintha kwake. Izi zimathandiza kupewa ming'alu yomwe imayamba chifukwa cha kuchepa kwa gawo lapansi kapena kuyenda.

Kupanga Mafilimu: HPMC imapanga filimu ikauma, yomwe imathandizira kukhazikika komanso kukana kwamadzi kwa khoma la putty, stucco kapena zokutira pamwamba. Imateteza pamwamba pa nthaka kuti isalowemo chinyezi ndikutalikitsa moyo wake.

Ndikofunikira kudziwa kuti kuchuluka kwenikweni kwa HPMC ndi zosakaniza zina zomwe zimapangidwira zimatha kusiyanasiyana malinga ndi zomwe mukufuna, njira yogwiritsira ntchito komanso momwe chilengedwe chimakhalira. Opanga ma putty pakhoma, pulasitala ndi zinthu zokutira zokutira nthawi zambiri amapereka chitsogozo pakugwiritsa ntchito moyenera HPMC muzolemba zawo zaukadaulo kapena mafotokozedwe azinthu.
