JINJI ® HPMC inoshandiswa muKuzvienzanisa
Kuzvimisa-leveling Misanganiswa yemakemikari inoshandiswa kutsvedzerera kongiri isina kuenzana kana pasi pemapuranga. Iwo anoumbwa nesamende, jecha, mafirita, uye akagadziridzwa nehuwandu hwekuwedzera senge cellulose ethers, plasticizers, defoamers, stabilizers, uye redispersible poda. Sechinhu chinoyerera, chinozvimisikidza uye chinozvinyevenutsa, makomisheni ekudzikamisa anogona kugadzira nzvimbo yakati sandara, yakatsetseka, uye yakaoma ine simba rekumanikidza.
Kuwedzerwa kweHPMC kunogona kusimudzira zvinotevera zvivakwa mu-self-leveling makomisheni maapplication:
Kuyerera
Sedhaka rekuzvimisa-leveling, fluidity ndechimwe chezviratidzo zvikuru zvekuongorora maitiro ekuzvimiririra. Pasi pemamiriro ekusimbisa mitemo yekuumbwa kwedhaka, iyo fluidity yedhaka inogona kugadziriswa nekushandura zviri mukati fiber HPMC. Nekudaro, zvakawandisa zvemukati zvinoderedza kuyerera kwedhaka, saka huwandu hweselulosi ether hunofanirwa kudzorwa mukati mehumwe hunoenderana.
Kuchengeta Mvura
Kuchengetedzwa kwemvura yedhaka chiratidzo chakakosha chekugadzikana kwezvikamu zvemukati zvesamende nyowani. Kuti uite kuti hydration reaction yeiyo gel zvinhu iitwe zvizere, huwandu hwakakodzera hweselulosi ether hunogona kuchengetedza mvura mudhaka kwenguva yakareba. Kazhinji, kuchengetwa kwemvura kweslurry kunowedzera nekuwedzera kwe cellulose ether content. Kuchengetwa kwemvura ye cellulose ether kunogona kudzivirira iyo substrate kuti isatore mvura yakawandisa nekukurumidza uye ichitadzisa kubuda kwemvura, nekudaro kuve nechokwadi chekuti slurry nharaunda inopa mvura yakakwana yesamende hydration. Mukuwedzera, iyo viscosity ye cellulose ether inewo chinhu chakakosha pakuchengetedza mvura kwedhaka. Iyo yakakwirira viscosity, zviri nani kuchengetedza mvura.
Kuisa nguva
HPMC ine inononoka kuseta mhedzisiro padhaka. Nekuwedzera kwe cellulose ether content, nguva yekugadzika yedhaka inowedzera. Kudzoreredza mhedzisiro ye cellulose ether pane simende slurry inonyanya kuenderana nehuwandu hwekutsiviwa kwealkyl group, iyo isinganyanyi kuenderana nehuremu hwayo hwemamorekuru. Iyo yakaderera dhigirii yealkyl inotsiva, iyo yakakwirira iyo hydroxyl zvirimo, zvakanyanya kuoneka kudzoreredza maitiro. Uye iyo yakakwirira yemukati ye cellulose ether, zvinonyanya kuoneka kudzoreredza kwemusanganiswa firimu pane yekutanga hydration ye simenti. Naizvozvo, iyo inonyanya kukosha iyo inononoka mhedzisiro.
Idhaka inozvimisa-yega inogona kuvimba nekuzviremera kuti igadzire hwaro hwakatsetseka, hwakatsetseka uye hwakasimba pane substrate yekuisa kana kubatanidza zvimwe zvinhu, uku ichibvumira kuvaka kwakanaka pamusoro penzvimbo yakakura.
