HPMC, wanda cikakken sunansa shine Hydroxypropyl Methylcellulose, ƙari ne na sinadarai masu aiki da yawa da aka saba amfani da shi wajen kayan gini. A cikin shimfidar fale-falen yumbu, HPMC tana taka muhimmiyar rawa kuma ana amfani da ita musamman a cikin tile adhesives, powders, da sauran turmi na gini don haɓaka aikin kayan aiki da sauƙin gini.
1.Basic Properties na HPMC
HPMC shine ether cellulose wanda aka yi daga cellulose na halitta da aka gyara ta hanyar sinadarai. Yana da kaddarorin masu zuwa:
Kauri: HPMC yana da ikon ƙara girman dankon ruwa ko kayan pasty, wanda ke da mahimmanci ga mannen tayal da turmi. Abu mai kauri yana da mafi kyawun mannewa kuma yana iya hana fale-falen fale-falen yadda ya kamata su zamewa yayin kwanciya.
Riƙewar Ruwa: HPMC yana riƙe da ruwa yadda yakamata a cikin kayan tushen siminti, yana ƙara buɗe lokacin turmi ko mannen tayal. Wannan yana nufin ma'aikata suna da ƙarin lokaci don daidaitawa lokacin shimfiɗa tayal, kuma yana taimakawa ciminti don cika ruwa sosai, haɓaka ƙarfin haɗin gwiwa na ƙarshe.
Lubricity: HPMC yana sa turmi ya zama ruwa kuma mai aiki, yana rage juzu'i yayin gini da barin ma'aikata su shimfiɗa tayal cikin sauƙi.
Adhesion: HPMC yana ba da kyawawan kaddarorin mannewa, yana sa haɗin gwiwa tsakanin fale-falen fale-falen ya fi ƙarfi da rage haɗarin fale-falen fale-falen.
2.Application a cikin yumbu tile kwanciya
A cikin shimfidar tayal yumbu, ana amfani da HPMC galibi azaman mai gyara ga mannen tayal da turmi. Musamman, HPMC ya taka rawa mai kyau a shimfidar yumbura a cikin abubuwan da ke biyowa:
Inganta aikin ginin: HPMC yana ƙara riƙe ruwa da aiki na manne tayal, yana bawa ma'aikata damar samun tsayin lokacin daidaitawa yayin shimfiɗa fale-falen ba tare da damuwa game da bushewar manne da sauri ba. Wannan yana rage yiwuwar sake yin aiki kuma yana inganta aikin gine-gine.
Ingantacciyar ingancin kwanciya: Ta hanyar haɓaka ƙarfin haɗin gwiwa na mannen tayal, HPMC yana taimakawa hana ingantattun matsalolin kamar faɗuwar fale-falen buraka yayin aikin bushewa. Har ila yau, kayan da ke daɗa kauri yana sa mannen tayal ɗin ƙasa da yuwuwar gudana yayin kwanciya a kan facade ko rufi, yana tabbatar da tsabta da ingancin ginin.
Mai daidaitawa da mahalli daban-daban na gine-gine: Kyakkyawan riƙewar ruwa ta HPMC yana ba da damar mannen tayal don kula da aikin ginin gini a yanayin zafi mai zafi ko bushewa, kuma ba zai haifar da ƙarancin mannewa ba saboda saurin ƙafewar ruwa.
3. Hattara yayin gini
Lokacin amfani da tile adhesive ko turmi dauke da HPMC, ma'aikata su kula da wadannan maki:
Dole ne madaidaicin ya zama daidai: adadin HPMC kai tsaye yana shafar aikin mannen tayal. Da yawa ko kaɗan zai haifar da rashin sakamako na ginin. Don haka, rabon ya zama daidai gwargwadon umarnin samfur.
Gaxa da kyau: Lokacin da ake yin tile ko turmi, HPMC yana buƙatar a haɗa shi sosai da sauran kayan don tabbatar da cewa ana iya amfani da kaddarorinsa daidai gwargwado. Haɗin da bai dace ba na iya haifar da rashin isassun mannewa na gida ko bushewa mara daidaituwa.
Tsaftace: Yayin aiwatar da shimfidar fale-falen yumbu, kayan aikin gini da muhalli yakamata a kiyaye su da tsafta don gujewa gurɓata abubuwan da ke haɗawa da kuma shafar tasirin haɗin gwiwa.
A matsayin ingantaccen ƙari na gini, HPMC tana taka rawar da ba za a iya maye gurbinsa ba a shimfidar tayal yumbu. Ba wai kawai yana haɓaka aikin mannen tayal da turmi ba, har ma yana inganta ingantaccen gini da ingancin ƙarshe. Don haka, HPMC abu ne mai mahimmanci kuma abu ne da ake amfani da shi sosai wajen ginin gine-gine na zamani.
