HPMC muWet Mortars
JINJI® Hydroxypropyl Methyl Cellulose (HPMC) isiri-ionic cellulose ether polymer yakavakirwa pa cellulose, yakasikwa polima inotorwa kubva kunatsa donje linter.
HPMC inogona kuvandudza kubatana uye kuchengetwa kwemvura yemusanganiswa weSpray mortar.
Mwero wekuchengetedza mvura indekisi yakakosha yekuita yeSpray Mortar. Nepo zvimwe zvikamu zvedhaka nekongiri zvakafanana, zvinoshanda zvakasiyana. Kazhinji, kongiri inodururwa mukongiri uye huni fomu basa rinochengeta yakawanda yemvura. Iyo dhaka inowanzoshandiswa pamvura inobata mvura, uye hunyoro huri mudhaka hunorasika nyore nyore kana kuti huputike mumhepo, saka kuchengetwa kwemvura kwedhaka kunova kwakakosha kudarika kwekrete.
Chikonzero nei HPMC ichiwedzera kuwirirana kwedhaka rekupfapfaidza kuchengetedza mvura, inogona kuvandudza kubatana kwedhaka, kuderedza kubuda kweropa kwedhaka kusvika kumwero wakati, asi kunatsiridza kuyerera kwedhaka rekupfapfaidza mukati meyero yakatarwa; Nekudaro, iyo yakakwira yeHydroxpropyl Methyl Cellulose inoita kuti iyo yakanyorova-musanganiswa dhaka inyanyobatana, iyo inoderedza kuyerera kwedhaka uye inoita kuti dhaka rinyanye kunetsa kuvaka.
HPMC inogona kuwedzera simba rekubatanidza remvura-yakasanganiswa dhaka.
Pakupurasita dhaka, kusimba kwechisungo chiratidzo chakakosha. Kazhinji kutaura, kupurasita dhaka kunoda kushanda zvakanaka. Kuti uite yunifomu yedhaka dhaka panzvimbo yekuvaka. Kusimba kwakasimba kwekubatana kwedhaka kunogona kuita kuti dhaka uye chigadziko chigadzikane zvakasimba, uye kushandiswa kwenguva refu hakuzokonzeri kuputika uye kudonha.
Iyo cellulose ether uye iyo hydration particles inoumba yakatetepa yepolymer firimu ine chisimbiso mhedzisiro uye kudzivirira kurasikirwa kwemvura, nekuchengetedza mvura zvakanaka, kuitira kuti ive nehunyoro hwakakwana kuti ive nechokwadi chekuyerera uye kusimba kwesimba resimende uye kugadzirisa simba rekubatanidza. zvepaste. Kune rimwe divi, Hydroxpropyl Methyl Cellulose inosimudzira kubatana kwedhaka rekupfapfaidza kuti ive nechokwadi chepurasitiki yayo yakanaka uye kuchinjika, inoderedza kutsvedza pakati pedhaka rekupfapfaidza uye substrate specimen interface, uye zvakare inovandudza iyo interface yekubatanidza kugona kwedhaka.
Zvinokurudzirwa kuti panguva yekugadzirira, HPMC inosanganiswa mumushonga wekupfapfaidza muchimiro chekugadzirisa pane kunyatsobatanidzwa nemhando yehupfu.
Iyo yekutanga ine mhedzisiro irinani pakuvandudza kuchengetwa kwemvura, kubatana, uye michina zvimiro zvespray mortar. Kana iyo yakashandurwa yemukati yeHydroxpropyl Methyl Cellulose iri muhuwandu hwe 0.01% ~ 0.04%, mwero wekuchengetedza mvura weHPMC mune mhinduro ndeye 1.4% ~ 3.0% yakakwirira kupfuura yehupfu hweHPMC mudhaka rekupfapfaidza. Naizvozvo, HPMC yakavhenganiswa muchimiro chemhinduro ine mhedzisiro iri nani pakuvandudza kuchengetwa kwemvura kwepfapfaidzo dhaka.
