Dry-mix dhaka zvigadzirwa zveindasitiri yekuvaka zvakafambira mberi zvakanyanya mumakore.Izvi zvigadzirwa zvave zvakakurumbira nekuda kwekureruka kwazvo, kuita zvakasiyana-siyana, uye nyore kushandisa.Kufambira mberi kwakakosha mune yakaoma-musanganiswa zvigadzirwa zvedhaka kushandiswa kwehydroxypropylmethylcellulose (HPMC) uye methylhydroxyethylcellulose (MHEC).Aya cellulose ethers anoshandiswa zvakanyanya mukugadzira dhaka dzakaoma-musanganiswa uye inopa vashandisi zvakawanda zvakanaka.Muchikamu chino, tinokurukura zvakanakira HPMC uye MHEC mune yakaoma-musanganiswa dhaka zvigadzirwa.
1. Kuchengeta mvura
Imwe yeakanakisa mabhenefiti eHPMC neMHEC mune yakaoma-yakasanganiswa dhaka zvigadzirwa kuchengetedza mvura.Aya cellulose ether anogona kubata mvura yakawanda uye kudzivirira kuti irege kubuda nekukasira.Izvi zvakakosha kune yakaoma-musanganiswa dhaka, izvo zvinoda kugara hydration kuitira kushanda kwakanyanya.HPMC neMHEC vanoshanda nekugadzira firimu rakatetepa rakatenderedza zvimedu zvedhaka, izvo zvinononotsa kubuda kwemvura.Somugumisiro, dhaka rinoramba richishandiswa kwenguva yakareba, rinoderedza mukana wekuputika uye rinowedzera chisungo.
2. Kuvandudza kunamatira
Zvigadzirwa zvedhaka zvakaomeswa zvinoshandisa HPMC neMHEC zvine kunamatira kuri nani pane zvigadzirwa zvedhaka zvakaomeswa zvisina cellulose ether.HPMC neMHEC vane yakanakisa adhesive zvivakwa, kuve nechokwadi chekuti dhaka rinonamatira kune substrate uye rinogara munzvimbo.Ivo zvakare vane epurasitiki-yakaita seyanamira mameseji ayo anokora dhaka uye anoita kuti zvive nyore kuisa.Izvi zvivakwa zvinoita kuti HPMC neMHEC ive yakanaka kune yakatwasuka maapplication uko giravhiti rinokwevera dhaka rakananga kumadziro.
3. Kuwedzera kusimba
HPMC neMHEC mune dzakaoma-musanganiswa wedhaka zvigadzirwa zvinowedzerawo kusimba kwechigadzirwa chekupedzisira.Cellulose ethers inodyidzana nesamende uye zvimwe zvinongedzo kugadzira zvimiro zvakatsiga uye zvakasimba.Iyo dhaka inogadzirwa hainyanyi kutsemuka, shrinkage uye mamwe maitiro ekuora.Uye zvakare, HPMC neMHEC vanoita kuti dhaka rirambe richidzivirira kumvura uye zvimwe zvinhu, kuve nechokwadi chehupenyu hwayo hwesevhisi.
4. Kuvandudza kushanda
Zvigadzirwa zvedhaka zvakaomeswa zvine HPMC neMHEC zvine hunyanzvi hwekushanda uye kuchinjika.Kushanda kwakanaka kweiyi cellulose ethers zvinoreva kuti madhaka ari nyore kusanganisa, kuisa uye kutsetseka.Ivo zvakare vanopa yakanakisa kuchinjika, ichibvumira iyo dhaka kuti iwedzere uye chibvumirano pasina kutsemuka kana kurasikirwa nehunhu hwayo.Uku kuchinjika kunonyanya kubatsira munzvimbo umo zvivakwa zvekuvaka zvinoratidzwa nekushanduka kwekushisa kana mamwe maitiro ekushushikana.
5. Enhanced Textures
Kana yawedzerwa kune yakaoma-musanganiswa madhaka, HPMC uye MHEC inopa akasiyana manyorerwo maitiro.Cellulose ethers inogadzira chimiro chakatsetseka, chine cream chinosimudzira kunaka kwedhaka.Kugadzirwa uku kunoitawo kuti dhaka rive nyore kushanda naro nekuti harizoregi kana kuputika.Saka kuti kutaridzika kweyakapedzwa yakaoma-yakasanganiswa dhaka chigadzirwa yunifomu uye yakanaka.
6. Zviri nyore kushandisa
Imwe mukana weHPMC uye MHEC mune yakaoma-yakavhenganiswa zvigadzirwa zvedhaka zviri nyore kushandisa.Aya cellulose ether ari nyore kusanganisa nekuisa uye haadi ruzivo rwenyanzvi kushandisa.Makondirakiti anogona kuzora dhaka vachishandisa nzira dzechinyakare dzakaita semabhurasho, ma roller, trowels kana pfuti dzekupfapfaidza.Izvi zvinoita kuti yakaoma-musanganiswa madhaka ane HPMC uye MHEC sarudzo yakanaka kune nyanzvi dzekuvaka uye DIYers zvakafanana.
7. Mutengo-kubudirira
Dry-mix mortar zvigadzirwa zvine HPMC uye MHEC zvakare inodhura-inoshanda.Aya ma cellulose ethers anotengeka uye anongoda mari shoma kuti awane mhedzisiro yaunoda.Pamusoro pezvo, HPMC neMHEC inobvumira marara mashoma, sezvo dhaka rinogara riine hydrate kwenguva refu.Nekuda kweizvozvo, pane kushomeka kwekugadzirisa kana kugadzirisa, kuderedza mutengo wezvinhu zvese.
Iko kushandiswa kweHPMC neMHEC mune yakaoma-musanganiswa zvigadzirwa zvedhaka inopa akawanda mabhenefiti kuindasitiri yekuvaka.Aya cellulose ethers anowedzera kuchengetwa kwemvura, kunamatira, kusimba, kugadzirisa, kuumbwa uye nyore kushandisa.Uyezve, ivo vane mari-inoshanda, vachivaita sarudzo inoyevedza yevaki nevaridzi vedzimba.Nekudaro, kutorwa kweiyi cellulose ethers muakaoma-musanganiswa dhaka kugadzirwa kungangoramba kuchikura mumakore anouya sezvo vavaki vachitsvaga kugadzira akasimba uye akavimbika zvivakwa.
