Hydroxypropylmethylcellulose (HPMC) inotorwa selulosi inoshandiswa zvakanyanya sebhainda uye mukobvu munzvimbo dzakasiyana siyana dzinosanganisira kuvaka, mishonga uye chikafu.HPMC imvura inonyungudika polymer iyo inogona kupa mabhenefiti makuru seanonamira muindasitiri yematairi.Muchikamu chino, tinokurukura basa rehydroxypropylmethylcellulose (HPMC) mumatairi anonamira.
introduce
Mataira anonamira zvinhu zvepolymer-based zvinoshandiswa kubatanidza mataira kune akasiyana substrates senge simende dhaka, kongiri, plasterboard uye mamwe mapeji.Mataira anonamira anogona kukamurwa kuita organic adhesives uye inorganic adhesives.Organic tile adhesives anowanzo akavakirwa pane ekugadzira mapolymers akadai epoxy, vinyl kana acrylic, nepo inorganic adhesives akavakirwa simende kana mineral zvinhu.
HPMC inoshandiswa zvakanyanya sekuwedzera mune organic tile zvinonamira nekuda kwezvakasiyana zvimiro zvakaita sekuchengetedza mvura, thickener, uye rheological properties.Izvi zvimiro zvakakosha kuve nechokwadi chekuti mataira anonamira akanyatso kusanganiswa, anosimudzira kushanda zvakanaka uye kuderedza nguva yekuomesa.HPMC inobatsirawo kuwedzera kusimba kweiyo tile yekunamatira, ichiita kuti igare yakasimba.
kuchengetedza mvura
Kuchengeta mvura chinhu chakakosha kuita kuti mataira anonamira asaoma nekukasira.HPMC chinhu chakanakisisa chekuchengetedza mvura, chinogona kuchengetedza kusvika ku80% yehuremu hwayo mumvura.Ichi chivakwa chinovimbisa kuti chinonamira chinoramba chichishandiswa kwenguva yakareba, ichipa iyo tile inogadzirisa nguva yakawanda yekuisa tile, kunyangwe zuva rese.Pamusoro pezvo, HPMC inosimudzira maitiro ekurapa, kuve nechokwadi chisungo chakasimba nekuvandudza kusimba.
thickener
Iyo viscosity yekunamatira mataira yakanangana nehupamhi hwemusanganiswa, inokanganisa kusununguka kwekushandisa uye kusimba kwechisungo.HPMC ndeye yakanyatso shanda thickener iyo inokwanisa kuwana yakakwira viscosities kunyangwe pakadzika kudzika.Nekudaro, vanogadzira mataira anonamira vanogona kushandisa HPMC kugadzira mataira anonamira ane kuenderana kwakakodzera chero chakananga chikumbiro chinodiwa.
Rheological properties
Iyo rheological properties yeHPMC inogona kuvandudza kushanda kwematairi anonamira.Viscosity inoshanduka nechiyero chekushandiswa kweshear stress, chivakwa chinozivikanwa sekuveura kutetepa.Shear kuonda kunonatsiridza kuyerera kweadhesive tile, zvichiita kuti zvive nyore kupararira pamusoro pemadziro uye pasi pasina kushanda nesimba.Pamusoro pezvo, HPMC inopa kunyange kugovera kwemusanganiswa, kudzivirira kudhumhana uye kusaenzana application.
Kuvandudza chisungo simba
Kuitwa kwematairi ekunamatira kunoenderana zvakanyanya nekusimba kwechisungo: iyo yekunamatira inofanira kunge yakasimba zvakakwana kuti ichengetedze tile yakanyatso kusungirirwa kumusoro uye kumira kushushikana kunogona kuita kuti tile iparare kana kushanduka.HPMC inobatsira kune ichi chivakwa nekusimudzira kunaka kwekunamatira uye nekuvandudza kunamatira kwayo.HPMC resins inogadzira yakakwirira-inoshanda mataira anonamira ane akakwira mazinga esimba rebhondi uye kuwedzera kusimba.Iko kushandiswa kweHPMC kunobatsira kudzivirira grout kana tile kutsemuka uye inochengeta tile yakasimba kwenguva yakareba yapera kutarisa.
mukupedzisa
Mukupedzisa, HPMC inosimudzira organic mataira anonamira nekupa akawanda mabhenefiti, anosanganisira kuchengetedza mvura, kukora, rheological zvivakwa uye yakagadziridzwa chisungo simba.Kugona kweHPMC kuvandudza kushanda, kuderedza kuomeswa nguva uye kudzivirira kuputika kwetairi kwakaita kuti ive chikamu chakakosha cheindasitiri yematairi.Kushandiswa kweHPMC mukugadzira mataira anonamira kunogona kuvandudza mhando yechigadzirwa uku ichipa yakasimba, yakasimba bonding mhinduro dzinoshanda sezvadzinofadza.Ese mabhenefiti aya anoratidza kuti HPMC imutambo-inoshandura polima mumusika uri kukura wematairi anonamira.
