Hydroxypropyl Methylcellulose (HPMC) ndi chowonjezera chomwe chimagwiritsidwa ntchito kwambiri pantchito yomanga. Ndi ether yopanda ionic, yosungunuka m'madzi ya cellulose ether yomwe imachokera ku cellulose yachilengedwe. HPMC ndi polima yosunthika kwambiri yomwe imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza zida zomangira. M'nkhaniyi, tikambirana za kugwiritsa ntchito HPMC muzomangamanga.

1. Mitondo ndi Plasters

HPMC amagwiritsidwa ntchito ngati thickener, binder, ndi madzi-kusunga wothandizila mu matope ndi pulasitala. Imawongolera kugwira ntchito, kumamatira, komanso kulimba kwa matope kapena pulasitala. HPMC imachepetsanso chiwopsezo chosweka ndikuwongolera mphamvu yamakomedwe amatope kapena pulasitala. Kugwiritsa ntchito HPMC mumatope ndi mapulasitala kumachepetsanso kuchuluka kwa madzi ofunikira, zomwe zingayambitse nthawi yowuma mofulumira komanso kuchepetsa kuchepa.

2. Zomatira za matailosi

Zomatira za matailosi zimagwiritsidwa ntchito kulumikiza matailosi kumadera osiyanasiyana. HPMC imagwiritsidwa ntchito ngati chowonjezera komanso chosungira madzi muzomatira matailosi. Imawongolera magwiridwe antchito komanso nthawi yotseguka ya zomatira, zomwe zimapangitsa kuti matailosi asinthe asanayambe kuyika zomatira. HPMC imathandizanso kumamatira kwa zomatira ku gawo lapansi ndi matailosi, zomwe zimachepetsa chiopsezo cha kutsekeka kwa matailosi.

3. Zodziyimira pawokha

Mankhwala odzipangira okha amagwiritsidwa ntchito kuti asagwirizane ndi malo otsetsereka. HPMC amagwiritsidwa ntchito ngati thickener ndi madzi-kusunga wothandizila pa kudziletsa leveling mankhwala. Imawongolera kutuluka ndi kuwongolera katundu wa pawiri, zomwe zimalola kuti zifalikire mofanana ndikupanga malo osalala. HPMC imachepetsanso chiwopsezo cha kusweka mwa kuwongolera mphamvu yamakomedwe a pawiri.

4. Exterior Insulation and Finishing Systems (EIFS)

EIFS ndi mtundu wamakina otsekera kunja omwe amagwiritsidwa ntchito poteteza komanso kuteteza nyengo ku nyumba. HPMC imagwiritsidwa ntchito ngati chowonjezera komanso chosungira madzi mu EIFS. Imawongolera magwiridwe antchito a EIFS, omwe amalola kuti igwiritsidwe ntchito bwino komanso molingana. HPMC imapangitsanso kumamatira kwa EIFS ku gawo lapansi, zomwe zimachepetsa chiopsezo chachitetezo.

5. Kumasulira kozikidwa pa simenti

Kumasulira kwa simenti kumagwiritsidwa ntchito kuti apereke mapeto okongoletsera kumakoma ndi malo ena. HPMC imagwiritsidwa ntchito ngati chowonjezera komanso chosungira madzi pomasulira zotengera simenti. Imawongolera magwiridwe antchito a kumasulira, zomwe zimapangitsa kuti zigwiritsidwe ntchito bwino komanso molingana. HPMC imapangitsanso kumamatira kwa kuperekedwa kwa gawo lapansi, zomwe zimachepetsa chiopsezo chachitetezo.

6. Zopangidwa ndi Gypsum

Zopangira zopangidwa ndi gypsum, monga zophatikizika ndi pulasitala, zimagwiritsidwa ntchito kuti zitheke bwino komanso zopanda msoko pamakoma ndi kudenga. HPMC imagwiritsidwa ntchito ngati chowonjezera komanso chosungira madzi muzinthu zopangidwa ndi gypsum. Zimapangitsa kuti ntchitoyo ikhale yogwira ntchito, yomwe imalola kuti igwiritsidwe ntchito bwino komanso mofanana. HPMC imathandizanso kumamatira kwa chinthucho ku gawo lapansi, zomwe zimachepetsa chiopsezo chachitetezo.

7. Zomatira za simenti

Zomatira zokhala ndi simenti zimagwiritsidwa ntchito kulumikiza zinthu zosiyanasiyana, monga matailosi, kugawo. HPMC imagwiritsidwa ntchito ngati chowonjezera komanso chosungira madzi muzomatira za simenti. Imawongolera kugwira ntchito kwa zomatira, zomwe zimapangitsa kuti zigwiritsidwe ntchito bwino komanso molingana. HPMC imathandizanso kumamatira kwa zomatira ku gawo lapansi ndi zinthu zomwe zimamangirizidwa, zomwe zimachepetsa chiopsezo chachitetezo.

8. Zopaka

Zovala, monga utoto ndi zosindikizira, zimagwiritsidwa ntchito kuteteza ndi kukongoletsa malo osiyanasiyana. HPMC amagwiritsidwa ntchito ngati thickener ndi madzi posungira wothandizila zokutira. Imawongolera magwiridwe antchito ndi kumamatira kwa zokutira, zomwe zimalola kuti zigwiritsidwe ntchito bwino komanso molingana. HPMC imapangitsanso kukhazikika kwa zokutira pochepetsa kuyamwa kwamadzi ndikuwongolera kukana kwanyengo ndi ma abrasion.
