Munzvimbo yekuvaka, yakaoma-inosanganisa motars ichitamba basa rekutyaira mukuona kusimba uye kutendeseka kwezvivakwa. Aya madota, anoumbwa nemhirizhonga yesimu, jecha, uye akasiyana siyana anowedzera, ipa zvizhinji zvakanaka pamusoro peiyo moter mauto. Imwe yakadaro yakadaro inokosha yekuwedzera ndeye hydroxypropyl methylcellose (HPMC). HPMC, inozivikanwa nekuwedzera kwakawanda uye kushanda kwayo, inosimbisa zvakanyanya kuita uye kushanda kwemauto akaoma-musanganiswa. Chinyorwa ichi chinotarisira kuyerera muzvikamu zveHPMC, kuongorora zvivakwa zvaro, zvinoshandiswa, uye zvinobatsira muindasitiri yekuvaka.
Kunzwisisa HpMC
HydroxyPropyl methylcellose (HPMC) ndeyako yekirasi ye cellulose ana vana, inotorwa kubva kune yakasikwa cellulose. Kuburikidza nenhevedzano yemakemikari yekugadziridzwa, cellulose inoisa kuwedzerwa kuburitsa HPMC. Iyo yakakosha idzo yeHPMC inoita chimwe chinhu chakakosha muzvikamu zvakaoma-monganda zvinosanganisira:
Kuchengeta kwemvura: HPMC ine simba rakanakisa kudzokorora kwemvura, ichigonesa kuti ichengetedze mvura mukati meiyo dhiriji. Hunhu uhwu hunoparadzanisa nekushanda kwenguva refu uye kudzivirira kusati kwatanga kuoma, kufambisa zvakanyanyisa kuderedza uye hydration ye simenti zvidimbu.
Kukakavara: HPMC inoita seyekuita mumiririri akaomesesa-musanganiswa monganda, kuvandudza mavhesi emusanganiswa. Iyi AIDS yeAIDS mukudzivirira kusarudzika kwesangano uye nekuvandudza kuwirirana kwemutumbi, nekudaro kufambisa nyore nyore kushandisa uye kuderedza marara.
ADHesion: HPMC inobatsira kuvandudza kuderedza pakati penzvimbo ine musoro uye substrate. Iyo inoumba firimu rakatetepa pane hydration, ichikurudzira kusungwa zviri nani uye kuderedza njodzi yekushongedza kana kudedera kwevhudzi.
Sag Kudzvinyirira: Kuwedzera kweHPMC kunopa SAG kupokana kune yakaoma-kusanganisa motsi, kunyanya vertical inonyorera sekurima kana kugadzirwa kwetile. Iyi imba inovimbisa kuti dhiza rinochengeta chimiro chayo uye haitsvaki kana deform panguva yekushandisa, zvichikonzera yunifomu uye anonakidza anofadza.
Zvikumbiro zveHPMC mune yakaoma-musanganiswa motsa
HPMC inowana yakashanda yakapararira pane dzakasiyana siyana mhando dzemhando dzakaoma-dzinosanganisa motsa, kusanganisira:
Tile Aomair: Mune Tile ADHESIVE FORFULATIONS, HPMC inoshanda seyakawandisa inowedzera kuti uvandudze kugona, kudzokorora kwemvura, uye kudedera zvivakwa. Iyo inovimbisa kunyorova kwakakodzera kweTile senSimber uye inosimudzira chisungo simba pakati pemataiti uye iyo substrate.
Plasingering motsi: HPMC inobatsira kukudziridza kwevhu rakakwira-mhando marara nekupa simba rakanakisa, Sag kuramba, uye kuderedza. Inogonesa kunyatsoshandiswa uye yunifomu yekushandisa yejasi remahara, zvichikonzera kusimbiswa kwekupedzesera uye kusimba.
Kuzvimiririra makomendi: HPMC inobatsira mune yekuumbwa kwezviyero zvekuzvimiririra zvinoshandiswa pasi pekuratidzira. Inobatsira kudzora iyo inoyerera zvivakwa zvemusanganiswa, ichiratidza kupatsanurana nyore uye nekukasira pamusoro pezvisikwa zvisina kuenzana zvichiramba zvichidzivirira kusarongeka uye kuderera.
Merarry Mortars: Mumauto masonry motsi, HPMC AIDS mukuvandudza kuchengetedzwa kwemvura, kushanda, uye kusungwa kwesimba. Iyo inosimudzira kubatana kweiyo moter musanganiswa, uchibvumira kubata zviri nani kubata uye kushandisa panguva yekubiridzira kana blockwork.
Zvakanakira Kushandisa HpMC mumotokari yakaoma-musanganiswa
Iko kubatanidzwa kweHPMC kunopa zvinokonzerwa zvakawanda kuomesa-musanganiswa mongwe mafomu ekugadzira:
Kuvandudzwa Kurovedzera: HPMC inoregedza yakavandudzwa zvivakwa zvevanyori kune moterr musanganiswa, zvichikonzera kusimudzira kugona uye kusununguka kwekushandisa. Makondirakiti anobatsirwa nekudzikiswa kuedza panguva yekusanganisa, kuendesa, uye kuisa mongwe, nekudaro nekuwedzera kubereka.
Kuvandudzwa Bond Simba: Kuvapo kweHPMC kunosimudzira zviri nani kushamwaridzana pakati pevhu uye substrate nzvimbo, zvichitungamira kuwedzera bond simba uye kuderedza njodzi yekukanganisa bond. Izvi zvinovimbisa kutendeka kwenguva refu kwekuvimbika uye kuita kwekuvakwa kwakapedzwa.
Kuenderana kwekuita: HPMC inoratidza zvinoenderana nekuita kwekuita huwandu hwemamiriro ekunze emamiriro ekunze, kusanganisira tembiricha uye humidity misiyano. Uku kuvimbika kunozivisa zvabuda zvinofungidzirwa maererano nemaumbirwo wekuenderana, kurongedza nguva, uye michina yezvimiro.
Yakaderedzwa Shrinkage Kurovera: Nekudzora kwemvura kubuda kwemvura uye nekuvandudza hydration ye simenti zvikamu, HPMC inobatsira kudzikisira shtery kupaza mumotokari yakaoma-musanganiswa. Izvi zvinoguma zvakaderedzwa zviitiko zvemusoro zvinokatyamadza uye zvinovandudza huwandu hwekukwirisa kwekukwirira kwechimiro chakapera.
HydroxyPropyl methylcellose (HPMC) inomiririra nedambudziko rakakosha mukuumbwa kwemauto akaoma, kupa zviuru zvezvakanaka zvekushanda uye kushamwaridzana nekuvandudza kusimba uye kupenga kuramba. Zvivakwa zvayo zvinoitika zvinoita kuti zvisakwanise kuyambuka mafambiro akasiyana siyana ekuvaka, kusanganisira tiles inonamira, inopararira motsi, yekuzvimiririra mauto, uye motoni masonry. Sezvo indasitiri yekuvaka ichiramba ichishanduka, HPMC inoramba iri chinhu chakakosha mukuzadzisa zvakakwirira-kuita uye kuchengetedza zvekuvaka mhinduro.
