Hydroxypropylmethylcellulose (HPMC) i polymer inoshanda zvakasiyana-siyana inoshandiswa zvakanyanya muindasitiri yekuvaka.Iyo isiri-chepfu, isinganhuhwi, pH-yakagadzika zvinhu zvakagadzirwa nekuunza hydroxypropyl uye methyl mapoka mune yakasikwa cellulose.HPMC inowanikwa mumhando dzakasiyana dzemagiredhi ane maviscosities akasiyana, particle saizi uye madhigirii ekutsiva.Ipolymer inonyungudika nemvura inogona kuumba gels pamatunhu akakwirira asi ine zvishoma kana kuti haina mhedzisiro paiyo rheology yemvura pakudzika kwakadzika.Ichi chinyorwa chinokurukura mashandisirwo eHPMC mune dzakasiyana siyana zvekuvaka.
Kushandiswa kweHPMC mukupurasita nekupa
Kuvakwa kwezvivakwa kunoda kuvandudzwa kwenzvimbo dzemadziro, pasi uye sirin'i.HPMC inowedzerwa kune gypsum uye plastering zvinhu kuti zviwedzere kushanda kwavo uye kunamatira.HPMC inovandudza kutsvedzerera uye kuenderana kwepurasita uye plastering zvinhu.Inowedzera simba rekuchengetedza mvura yezvisanganiswa, zvichiita kuti zvibatanidze zviri nani kumadziro kana pasi.HPMC inobatsirawo kudzivirira shrinkage uye kuputika panguva yekurapa uye kuomesa, kuwedzera kusimba kwejasi.
Kushandiswa kweHPMC mukunamatira mataira
Mataira anonamira chikamu chakakosha chezvirongwa zvekuvaka zvemazuva ano.HPMC inoshandiswa mumatairi anonamira kuvandudza kunamatira kwavo, kuchengetedza mvura uye kuita kwekuvaka.Kuwedzera HPMC kune inonamira dhizaini inowedzera zvakanyanya kuvhurika nguva yekunamatira, ichipa vanoisa nguva yakawanda yekuita zvigadziriso tisati taseta tile.HPMC inowedzerawo kuchinjika uye kusimba kweiyo bondline, kuderedza njodzi yeku delamination kana kutsemuka.
Kushandiswa kweHPMC mune yega-leveling makomisheni
Mishonga yekuzvimisa-leveling inoshandiswa kuyera pasi uye kugadzira yakatsetseka, yakaenzana nzvimbo yekuisa zvinhu zvepasi.HPMC inowedzerwa kune yega-leveling makomisheni kuti ivandudze kuyerera kwavo uye kuenzana zvivakwa.HPMC inoderedza iyo yekutanga viscosity yemusanganiswa, zvichiita kuti zvive nyore kuisa nekuvandudza kuenzana.HPMC inowedzerawo kuchengetwa kwemvura yemusanganiswa, kuve nechokwadi chesimba rebhondi pakati pezvinhu zvepasi uye substrate.
Kushandiswa kweHPMC mune caulk
Grout inoshandiswa kuzadza mapundu pakati pemataira, dombo rechisikigo kana zvimwe zvinhu zvepasi.HPMC inowedzerwa kune yakasanganiswa kombi kuti ivandudze kuita kwayo kuvaka uye kusimba.HPMC inowedzera viscosity yemusanganiswa, zvichiita kuti zvive nyore kuparadzira uye kuderedza shrinkage uye kuputika kwezvinhu zvekuzadza panguva yekurapa.HPMC zvakare inonatsiridza kunamatira kwekuzadza kune substrate, ichideredza mukana weamangwana mapundu uye makatsemuka.
HPMC mune gypsum-based zvigadzirwa
Zvigadzirwa zveGypsum, senge plasterboard, sirin'i mataira uye mabhodhi ekudzivirira, anoshandiswa zvakanyanya muindasitiri yekuvaka.HPMC inoshandiswa mune gypsum yakavakirwa zvigadzirwa kuvandudza kushanda kwavo, kuseta nguva uye simba.HPMC inoderedza kudiwa kwemvura yekugadzira, ichibvumira kune yakakwirira solids yemukati, iyo inowedzera simba uye kusimba kwechigadzirwa chakapedzwa.HPMC zvakare inovandudza kunamatira pakati peiyo gypsum particles uye substrate, kuve nechokwadi chisungo chakanaka.
mukupedzisa
Hydroxypropylmethylcellulose (HPMC) i polymer inoshanda zvakasiyana-siyana inoshandiswa mumhando dzakasiyana siyana dzekuvaka.HPMC inonatsiridza mashandiro egypsum uye plastering zvinhu, zvinonamira mataira, self-leveling compounds, grouts uye gypsum-based products.Kushandisa HPMC mune izvi zvinhu kunovandudza processability, adhesion, kuchengetedza mvura uye kusimba.Nekudaro, HPMC inobatsira kugadzira yakasimba, yakasimba, yakasimba, inogara kwenguva refu zvivakwa zvinosangana nezvinodiwa zvepamusoro zvezvivakwa zvemazuva ano.
