Hydroxypropyl methylcellulose (HPMC) abu ne mai mahimmanci na polymer, wanda galibi ana amfani dashi a cikin yadudduka na saka a cikin filin gini. Zai iya inganta haɓaka aikin gini da ingancin putty. Ba zai iya inganta aikin ginawa kawai ba, amma kuma yana haɓaka mannewa, riƙewar ruwa da juriya, don haka ana girmama shi sosai a cikin ginin.
1. Basic halaye na HPMC
HPMC shine ether cellulose maras ionic, wanda aka gyara ta hanyar sinadarai daga cellulose na halitta. Maganin sa na ruwa mai ruwa yana da kyakkyawar riƙewar ruwa, kauri da mannewa, kuma ana iya daidaita shi da buƙatun aikace-aikacen daban-daban a cikin yanayin gini. Bayan an narkar da HPMC a cikin ruwa, zai iya samar da ingantaccen maganin colloidal na gaskiya, wanda ƙimar pH ba ta iya tasiri cikin sauƙi. Bugu da kari, shi ma yana da karfi juriya ga enzymatic hydrolysis, hadawan abu da iskar shaka juriya, haske juriya, acid juriya, alkali juriya da sauran halaye, wanda damar HPMC don kula da kyau yi a daban-daban gina muhallin.
2. The aiki ka'idar na HPMC a putty Layer
A cikin Layer putty, HPMC galibi yana taka rawa kamar haka:
Haɓaka riƙon ruwa: HPMC yana da ƙarfin riƙe ruwa mai ƙarfi, wanda zai iya hana ruwan da ke cikin Layer ɗin putty yadda ya kamata daga ƙafewa da sauri. A lokacin aikin gina jiki, farfajiyar za ta hanzarta bushewa saboda ƙawancen ruwa, amma kasancewar HPMC na iya kiyaye Layer na putty a babban abun ciki na danshi, ta haka zai kara lokacin budewa na putty, wanda zai dace da ma'aikatan ginin don gyarawa. da daidaitawa, sannan kuma yana taimaka wa putty don samun ƙarfi sosai da guje wa fashewar bushewa da sauri.
Inganta thickening: HPMC yana da wani thickening sakamako, wanda zai iya ba da putty slurry mafi danko, game da shi inganta ta aikace-aikace yi. Ƙaƙwalwar putty yana buƙatar wani danko don sauƙaƙe ginawa, yayin da tabbatar da cewa za a iya rarraba putty a ko'ina kuma a manne da bangon. Tasirin kauri na HPMC na iya taimakawa Layer putty don kula da daidaiton daidaituwa, yana sa aikin ya fi sauƙi kuma yana rage yanayin sagging da zamewa yayin gini.
Haɓaka juriya na tsaga: Matsalar gama gari a cikin tsarin bushewa na Layer putty shine ƙirƙirar ƙananan fasa, wanda ke shafar ingancin samfurin da aka gama. HPMC na iya hana tsagewa a cikin Layer na putty saboda yana iya samar da tsayayyen tsarin hanyar sadarwa na fiber bayan an warke putty, ta haka yana haɓaka taurin putty da rage tsagewar da ke haifar da bushewa da damuwa da zafin jiki.
Inganta aikin gini: HPMC na iya inganta santsin aikin gini, yana sa ya zama ƙasa da yuwuwar samun matsaloli kamar wutsiya da alamar wuƙa yayin aikin ginin. Maganin colloidal da HPMC ya kafa a cikin ruwa yana da tasiri mai kyau na lubricating, wanda zai iya sa kayan shafa ya fi sauƙi a lokacin da ake yin laushi da gogewa, don haka rage wahalar gini.
Haɓaka mannewa: HPMC na iya inganta mannewa tsakanin mannewa da bangon tushe, yana hana mannewa daga faɗuwa ko kumbura. Maganin colloidal da aka kafa ta HPMC a cikin putty za a iya haɗa shi tare da tushe na tushe don ƙara ƙarfin mannewa na putty. Wannan mannewa mai kyau na iya tabbatar da cewa Layer na putty ya kasance barga na dogon lokaci bayan an gina shi, inganta ƙarfin tasirin kayan ado na gaba ɗaya.
3. Fa'idodi da iyakokin aikace-aikacen HPMC
Fa'idodin HPMC a cikin aikace-aikacen yadudduka na putty galibi suna nunawa a cikin abubuwan da ke biyowa:
Haɓaka aikin sa kayan aiki: Tun da HPMC na iya tsawaita lokacin buɗe kayan sawa, ma'aikatan gini za su iya kammala aikin putty a cikin isasshen lokaci, rage lokacin da ake buƙata don maimaita aikace-aikacen, da kuma rage wahalar gini.
Ajiye kayan sawa: Tasirin kauri na HPMC na iya rage canjin ruwa, ta haka zai ƙara daidaiton putty, sa putty ya fi tattalin arziki, rage adadin kayan sakawa, da rage farashin gini.
Aiwatarwa zuwa bangon bango iri-iri: HPMC na iya daidaita da kyau ga subesrates kamar su kayan adon da kuma kayan aikin gini don nau'ikan kayan gini daban-daban.
Ƙarfin daidaitawa ga yanayi: Tun da HPMC yana da ƙarfin riƙewar ruwa da kwanciyar hankali, ko da an gina shi a cikin yanayi mai zafi ko ƙarancin zafi, zai iya hana saurin asarar ruwa a cikin Layer na putty kuma tabbatar da kyakkyawan sakamako na putty.
IV. Kariya don amfani da HPMC
A cikin ainihin aikace-aikacen, adadin da hanyar ƙara HPMC zai shafi aikin ƙarshe na putty. A ƙarƙashin yanayi na al'ada, adadin HPMC da aka ƙara yakamata ya zama matsakaici. Idan an ƙara da yawa, lokacin bushewa na Layer putty na iya tsawaita, yana shafar ci gaban ginin. Sabili da haka, lokacin amfani da shi, adadin ya kamata a sarrafa shi daidai gwargwadon halaye na samfurin putty da yanayin gini. Bugu da ƙari, HPMC ya kamata a adana shi a cikin yanayi mai laushi don hana shi daga ɗaukar danshi da haɓaka, wanda zai shafi tasirin amfani.
Aikace-aikacen HPMC a cikin Layer na sakawa yana inganta ingantaccen aiki, riƙewar ruwa da juriya na fashe, yana ba shi damar kula da kyakkyawan sakamako a ƙarƙashin yanayin gini daban-daban. Ta ƙara adadin da ya dace na HPMC, maginin zai iya sarrafa tsarin aikin sa cikin sauƙi, inganta shimfidar shimfidar wuri da ingancin samfurin da aka gama. Sabili da haka, aikace-aikacen HPMC a cikin Layer na putty ba zai iya inganta tasirin ginin ba kawai, amma kuma ya kara tsawon rayuwar sabis na kayan ado, yana ba da garanti mai karfi don bayyanar da ciki na ginin.
