Kugwiritsa Ntchito HPMC:
Adhesive matailosi
● Kusunga madzi bwino: Kutsegula kwa nthawi yaitali kumapangitsa kuti matayala azikhala bwino.
● Kumamatira bwino komanso kukana kutsetsereka: makamaka kwa matailosi olemera.
● Kugwira ntchito bwino: kutsekemera ndi pulasitiki wa pulasitala kumatsimikiziridwa, matope amatha kuikidwa mosavuta komanso mofulumira.
Simenti Plaster / Dry Mix matope
● Kusakaniza kosavuta kowuma chifukwa cha kusungunuka kwa madzi ozizira: mapangidwe a zotupa amatha kupewedwa, abwino kwa matailosi olemera.
● Kusungirako bwino kwa madzi: kupewa kutaya madzi kumagulu apansi, madzi oyenerera amasungidwa mosakaniza zomwe zimatsimikizira nthawi yaitali ya concreting.
● Kuchuluka kwa madzi: nthawi yotseguka yowonjezereka, malo otambasula a spry ndi kupanga ndalama zambiri.
● Kufalira kosavuta komanso kukhazikika kolimba chifukwa cha kusasinthika.
Wall putty
● Kusunga madzi: kuchulukitsa madzi mu slurry.
● Anti-sagging: pamene kufalitsa corrugation thicker malaya akhoza kupewedwa.
● Kuchuluka kwa zokolola zamatope: kutengera kulemera kwa kusakaniza kowuma ndi kapangidwe koyenera, HPMC ikhoza kuonjezera voliyumu yamatope.
Exterior Insulation and Finish System (EIFS)
●Kumamatira bwino.
● Kunyowetsa bwino kwa bolodi la EPS ndi gawo lapansi.
● Kuchepa kwa mpweya komanso kutuluka kwa madzi.
Kudzikweza
● Kutetezedwa ku madzi otuluka m'madzi ndi matope.
● Palibe zotsatira pa slurry fluidity ndi otsika mamasukidwe akayendedwe
HPMC, pomwe mawonekedwe ake osungira madzi amawongolera magwiridwe antchito pamtunda.
Crack Filler
● Kugwira ntchito bwino: makulidwe oyenera ndi pulasitiki.
● Kusunga madzi kumapangitsa kuti ntchito ikhale yaitali.
● Sag resistance: kupititsa patsogolo luso lomangirira matope.
