A lokacin da ake hadawa da kuma aikin gina foda, tasirin lubrication na HPMC yana sa ya zama mai sauƙi don motsa ƙwayar sa a ko'ina kuma a shafa shi a bango. Wannan ba kawai ya sa ginin ya fi dacewa ba, amma har ma yana rage lalacewa da tsagewar kayan aikin gini.
5. Kwanciyar hankali
HPMC na iya inganta ingantaccen kwanciyar hankali na putty foda. Yana iya hana putty foda daga daidaitawa, agglomerating da sauran matsalolin yayin ajiya kuma tabbatar da kwanciyar hankali na samfurin. Wannan sakamako mai ƙarfafawa na HPMC yana hana ƙwayar putty daga motsawa akai-akai kafin amfani da kuma kula da ingancin iri.
6. Inganta aikin anti-slip
Lokacin gina ganuwar a tsaye, idan foda mai ɗorewa ba shi da kyawawan kaddarorin anti-slip, yana da saurin sagging da sagging. Adhesion da thickening effects na HPMC muhimmanci inganta anti-zamewa yi na putty foda, tabbatar da cewa kayan za a iya da tabbaci a haɗe bango don samar da lebur, m surface.
7. Haɓaka haɓakawa
Kasancewar HPMC yana sa foda mai sauƙi don ginawa, yana rage manne kayan aiki, kuma yana inganta ingantaccen gini. Zai iya sa foda mai ɗorewa ba zai iya yin amfani da kayan aiki a lokacin aikin ginin ba, rage juriya a lokacin aikace-aikacen, da kuma inganta jin dadi da tasiri na ginin.
8. Daidaita lokutan budewa
HPMC na iya daidaita lokacin buɗewar foda. Lokacin buɗewa yana nufin lokacin da za'a iya gyara foda na putty da gyara bayan ginawa. Ta hanyar sarrafa adadin HPMC da aka ƙara, lokacin buɗewa na putty foda za a iya tsawaita shi daidai ko rage don daidaitawa da bukatun gine-gine daban-daban.
9. Inganta juriya
Saboda kauri da kaddarorin riƙe ruwa na HPMC, zai iya hana ƙwayar putty yadda ya kamata daga raguwa da fashe saboda asarar ruwa mai yawa yayin aikin bushewa. Zai iya samar da elasticity mai dacewa, yana barin busassun busassun putty don tsayayya da damuwa na waje da kuma rage abin da ya faru na fashe.
10. Inganta juriyar yanayi
HPMC na iya haɓaka juriya na yanayi na putty foda da hana tsufa da tabarbarewar Layer na putty a cikin yanayi mara kyau. Saboda abubuwan samar da fina-finai da kwanciyar hankali na HPMC, yana iya tsayayya da yashwar ultraviolet da sauye-sauyen zafi yadda ya kamata, yana haɓaka rayuwar sabis na foda.
HPMC tana taka rawa da yawa a cikin foda. Daga riƙewar ruwa, thickening, da kuma samar da fina-finai don haɓaka aikin gine-gine da inganta juriya na tsagewa, yana taka muhimmiyar rawa a cikin aikin aiki da aikin gina jiki na putty foda. Aikace-aikacen sa yana sa foda mai sanyawa ya sami kyakkyawan aikin gini, kwanciyar hankali da karko, yana ba da garanti mai mahimmanci don ginin bango. A takaice, HPMC wani abu ne mai mahimmanci kuma mai mahimmanci na putty foda kuma yana taka rawar da ba za a iya maye gurbinsa ba don inganta aikin gaba ɗaya na putty foda.
