Self-leveling compounds (SLC) inokurumidza-kuomesa uye inochinja-chinja zvinhu zvepasi izvo zviri kuramba zvichizivikanwa nekuda kwekusimba kwazvo uye nzvimbo yakatsetseka.Iwo anoshandiswa zvakanyanya munzvimbo dzekugara uye dzekutengesa kuyera kongiri nzvimbo isati yaisa kapeti, vinyl, huni kana mataira pasi.Nekudaro, kuita kweSLCs kunogona kukanganiswa neakasiyana ezvakatipoteredza zvinhu senge tembiricha, humidity, uye substrate adhesion.Kuti uwedzere mashandiro emakomisheni ekuzvimiririra, vagadziri vatanga kuwedzera hydroxypropylmethylcellulose (HPMC) uye hydroxyethylmethylcellulose (HEMC) seyakakora.
HPMC i polymer inonyungudika mumvura inoumba gel yakagadzikana kana yakaparadzirwa mumvura.Iyo inowanzoshandiswa mukugadzira zvikumbiro nekuda kwekunaka kwayo kuchengetedza mvura uye inonamira zvivakwa.Kana yawedzerwa kune yega-leveling makomisheni, HPMC inovandudza kuyerera uye kushanda kwemusanganiswa.Iyo zvakare inoderedza huwandu hwemvura inodiwa kuti uwane iyo inodiwa kuenderana, kudzivirira shrinkage uye kuputika panguva yekurapa.Uye zvakare, HPMC inogona kuwedzera iyo yakabatana simba reSLC, nekudaro ichivandudza kupfeka kwayo kuramba.
HEMC imwe polymer inonyungudika nemvura inoshandiswa zvakanyanya muindasitiri yekuvaka seyakakora uye rheology control agent.Inogona kuvandudza kunamatira, kubatana uye kuenderana kwezvinhu zvekuvaka, zvichiita kuti ive yakakurumbira yekuwedzera muSLC.Kana yawedzerwa kuSLC, HEMC inowedzera viscosity yemusanganiswa, ichibvumira kupararira zvakanyanya uye kunamatira zviri nani kune substrate.Iyo zvakare inonatsiridza iyo yekuzvimisikidza zvimiro zvekomboni, ichidzikisa mukana wekukanganisa kwepamusoro senge pinholes uye mabhuru emhepo.Uye zvakare, HEMC inowedzera iyo yakazara mechanical simba reSLC, ichiita kuti ive yakasimba uye isingaite kukuvara.
Imwe yemabhenefiti makuru ekushandisa HPMC neHEMC mu-self-leveling makomisheni ndeyekuti ivo vanovandudza kushanda kwemusanganiswa.Izvi zvinoreva kuti makondirakiti anogona kudurura nekuparadzira SLC zviri nyore, kuderedza huwandu hwebasa rinodiwa pabasa.Zvakare, kuwedzera HPMC uye HEMC kuSLC kunobatsira kupfupisa nguva yekuomesa yemusanganiswa.Izvi zvinodaro nekuti zvinodzivirira mvura yemusanganiswa kubva mukubuda, zvichikonzera kuti pave nekuenzana uye kusingachinji nzira yekurapa.
Imwe bhenefiti yekushandisa HPMC neHEMC mu-self-leveling makomisheni ndeyekuti ivo vanovandudza huwandu hwese hwepasi rakapedzwa.Kana yawedzerwa kumusanganiswa, aya mapolymer anowedzera kunamatira kweSLC kune substrate, kuderedza mukana wekukundikana kwebhondi.Izvi zvinovimbisa kuti pasi rinogara kwenguva yakareba uye rinoramba rakasimba kunyangwe mumotokari inorema.Pamusoro pezvo, kushandiswa kweHPMC neHEMC kunogadzira nzvimbo yakatsetseka, yakadzikama inoita kuti zvive nyore kuisa zvimwe zvinhu zvepasi pamusoro.
Panyaya yemutengo, kuwedzera HPMC neHEMC kune ega-leveling makomisheni kune isingadhure.Aya mapolymers anowanikwa zviri nyore mumusika uye anogona kuiswa nyore muSLC masanganiswa panguva yekugadzira.Kazhinji, mashoma chete eHPMC neHEMC anodiwa kuti uwane kuenderana uye kuita kunodiwa kuSLC, iyo inobatsira kuchengetedza mutengo wekugadzira wakaderera.
Chekupedzisira asi chisiri chidiki, kushandiswa kweHPMC neHEMC mumakomisheni ega-leveling imhinduro ine hushamwari.Aya mapolymers anoodza uye haana chero zvinhu zvine njodzi, zvichireva kuti haana njodzi kuhutano hwevanhu kana nharaunda.Kushandiswa kwavo muSLC kunobatsira kusimudzira muindasitiri yekuvaka, chinhu chakakosha kufunga munyika yanhasi.
Kuwedzera HPMC neHEMC kumakomisheni ega-leveling kune akawanda mabhenefiti, zvichiita kuti ive mhinduro yakanaka kune makondirakiti nevagadziri.Aya mapolymers anovandudza mashandiro emusanganiswa, kuderedza nguva yekuomeswa, kuvandudza kunaka kwepasi rakapedzwa, chengetedza mutengo wekugadzira wakaderera uye kusimudzira kusimudzira.Sezvo indasitiri yekuvaka ichiramba ichitsvaga mhinduro nyowani dzekuvandudza kushanda, kunaka uye kusimba kwezvigadzirwa zvayo, isu tingangoona kushandiswa kwakakura kweHPMC neHEMC muSLC mune ramangwana.
