Ɗaya daga cikin abubuwan da ake amfani da su a cikin bushe-mix turmi shine hydroxyethyl cellulose (HEC). HEC shine ether cellulose maras ionic tare da kauri, riƙe ruwa, daidaitawa, da kaddarorin dakatarwa. An yi amfani da shi sosai a cikin kayan gini, musamman a cikin bushe-mix turmi.
1. Matsayin HEC a cikin bushe-mix turmi
A cikin busassun turmi, HEC galibi yana taka rawa na riƙe ruwa, kauri da haɓaka aikin gini:
Riƙewar ruwa: HEC yana da kyakkyawar riƙewar ruwa kuma yana iya rage asarar ruwa. Wannan yana da mahimmanci musamman ga bushe-bushe turmi domin yana tsawaita lokacin buɗe turmi, yana bawa ma'aikata damar daidaita turmi na tsawon lokaci da haɓaka aikin ginin. Bugu da ƙari, riƙewar ruwa zai iya rage haɗarin fashewa da kuma tabbatar da cewa tsarin taurin turmi ya fi daidai kuma yana da kwanciyar hankali.
Thickening: Sakamakon thickening na HEC yana ba da turmi mai kyau danko, ƙyale turmi ya fi dacewa da yanayin da ake yi a lokacin ginawa, ba sauƙin zamewa ba, kuma yana inganta daidaituwa na aikace-aikacen. Wannan sifa tana da mahimmanci musamman a ginin a tsaye kuma yana iya haɓaka ingancin ginin turmi sosai.
Inganta aikin gine-gine: HEC na iya yin busassun turmi mai gauraya da sauƙi da sauƙin amfani, don haka rage wahalar aiki. Yana sa turmi ya sami kyakkyawan shimfidawa da mannewa a kan ma'auni, yana sa gini ya zama mafi ceton aiki da inganta ingantaccen aiki. Bugu da ƙari, yana iya ƙara ƙarfin hana sagging, musamman a cikin ginin Layer mai kauri.
2. Ma'aunin zaɓi na HEC
Lokacin zabar HEC, ya kamata a yi la'akari da dalilai kamar nauyin kwayoyin sa, digiri na maye da solubility, wanda zai shafi aikin turmi kai tsaye:
Nauyin kwayoyin halitta: Girman nauyin kwayoyin halitta yana rinjayar ikon yin kauri da tasirin ruwa na HEC. Gabaɗaya magana, HEC tare da nauyin ƙwayar ƙwayar ƙwayar cuta mafi girma yana da mafi kyawun sakamako mai kauri, amma ƙarancin narkewa; HEC tare da ƙaramin nauyin kwayoyin halitta yana da saurin rushewa da ɗan ƙaramin sakamako mai kauri. Sabili da haka, wajibi ne don zaɓar nauyin kwayoyin da ya dace bisa ga bukatun gini.
Digiri na maye gurbin: Matsayin maye gurbin HEC yana ƙayyade solubility da kwanciyar hankali. Matsayi mafi girma na maye gurbin, mafi kyawun solubility na HEC, amma danko zai ragu; lokacin da matakin maye gurbin ya yi ƙasa, danko ya fi girma, amma solubility na iya zama matalauta. Gabaɗaya, HEC tare da matsakaicin matsayi na canji ya fi dacewa don amfani da busassun busassun turmi.
Solubility: Yawan rushewar HEC yana rinjayar lokacin shirye-shiryen ginin. Don busassun busassun turmi, ya fi dacewa don zaɓar HEC mai sauƙi don tarwatsawa da narke da sauri don inganta sassaucin ginin.
3. Kariya lokacin amfani da HEC
Lokacin amfani da HEC, kuna buƙatar kula da ƙarin adadin sa da yanayin amfani don tabbatar da mafi kyawun sakamako:
Ƙarfafa adadin adadin: Ƙarin adadin HEC yawanci ana sarrafawa tsakanin 0.1% -0.5% na jimlar nauyin turmi. Ƙarfafawa mai yawa zai sa turmi ya yi kauri da yawa kuma ya shafi aikin ginin; rashin isasshen ƙari zai rage tasirin riƙe ruwa. Don haka, yakamata a gudanar da gwajin bisa ga ainihin buƙatun don tantance mafi kyawun adadin kari.
Dace da sauran additives: A cikin bushe-mixed turmi, HEC sau da yawa ana amfani da a hade tare da sauran Additives kamar redispersible latex foda, cellulose ether, da dai sauransu Kula da dacewa da HEC da sauran sinadaran don tabbatar da cewa babu wani rikici da kuma tasiri. tasirin.
Yanayin ajiya: HEC yana da hygroscopic, ana bada shawara don adana shi a cikin wuri mai bushe kuma kauce wa hasken rana kai tsaye. Ya kamata a yi amfani da shi da wuri-wuri bayan buɗewa don hana lalacewar aiki.
4. Sakamakon aikace-aikacen HEC
A cikin aikace-aikacen aikace-aikacen, HEC na iya haɓaka aikin ginin busassun busassun turmi da haɓaka ingancin turmi gabaɗaya. Sakamakon kauri da kuma riƙe ruwa na HEC yana sa turmi mai bushe-bushe yana da kyau adhesion da kwanciyar hankali, wanda ba kawai inganta ingancin ginin ba, amma kuma yana tsawaita lokacin bude turmi, yana bawa ma'aikata damar yin aiki cikin kwanciyar hankali. Bugu da ƙari, HEC na iya rage abin da ya faru na fashewa a saman turmi, yana sa turmi mai taurin ya fi tsayi da kyau.
5. Kare muhalli da tattalin arzikin HEC
HEC wani nau'in cellulose ne wanda ke da alaƙa da muhalli wanda ba zai iya lalata ba kuma yana da alaƙa da muhalli. Bugu da kari, HEC yana da ɗan matsakaicin farashi kuma yana da tsada, yana mai da shi dacewa don haɓaka haɓakawa da aikace-aikace a cikin nau'ikan ayyukan gini daban-daban. Yin amfani da HEC na iya rage rabon ruwa da siminti na turmi, ta yadda za a rage yawan ruwa, wanda kuma ya yi daidai da yanayin kare muhalli na kore a cikin masana'antar gine-gine.
Aiwatar da HEC a cikin busassun turmi mai gauraya na iya inganta aikin turmi sosai kuma ƙari ne da ba makawa a cikin gini. Kyakkyawan riƙewar ruwa, kauri da daidaitawar ginin yana haɓaka haɓaka aikin gini kuma yana sa inganci ya fi kwanciyar hankali. Zaba
HEC daidai da yin amfani da shi yadda ya kamata ba zai iya inganta ingancin ginin kawai ba, har ma ya dace da kariyar muhalli da bukatun tattalin arziki.
