Hydroxypropyl methylcellulose (HPMC) ƙari ne mai amfani da yawa a cikin masana'antar gini, musamman a cikin ƙirar filasta.Gypsum plaster, wanda kuma aka sani da filastar na Paris, sanannen kayan gini ne da ake amfani da shi don yafa bango da silin.HPMC tana taka muhimmiyar rawa wajen haɓaka aiki da aikin filastar gypsum.
HPMC shine ether cellulose maras ionic wanda aka samo daga cellulose polymer na halitta ta hanyar jerin gyare-gyaren sinadarai.Ana samar da ita ta hanyar maganin cellulose tare da propylene oxide da methyl chloride.Samfurin da aka samu shine farin foda wanda ke narkewa a cikin ruwa kuma yana samar da bayani mai haske.
Ga wasu mahimman abubuwan HPMC don filasta:
1. Riƙe ruwa:
Ɗaya daga cikin manyan ayyuka na HPMC a cikin gypsum shine ƙarfin riƙe ruwa.Yana taimakawa hana saurin asarar danshi yayin aikin bushewa, yana ba da damar ƙarin sarrafawa har ma da saitin filasta.Wannan yana da mahimmanci don cimma ƙarfin da ake buƙata da daidaito na filastar.
2. Inganta iya aiki:
HPMC yana haɓaka aikin filastar gypsum ta hanyar samar da mafi kyawun lokacin buɗewa da haɓaka juriya.Wannan ya sa ya fi sauƙi a yi amfani da shi da kuma yada stucco a kan saman, yana haifar da sauƙi, har ma da ƙarewa.
3. Adhesion da haɗin kai:
HPMC yana taimakawa a manne da filastar gypsum zuwa sassa daban-daban.Yana inganta mannewa tsakanin stucco da saman da ke ƙasa, yana tabbatar da ƙarewa mai dorewa kuma mai dorewa.Bugu da ƙari, HPMC yana haɓaka haɗin kai da filastar kanta, don haka ƙara ƙarfi da rage raguwa.
4. Tasiri mai kauri:
A cikin tsarin gypsum, HPMC yana aiki azaman mai kauri, yana shafar danko na cakuda gypsum.Wannan sakamako mai kauri yana da mahimmanci don cimma daidaito da rubutu da ake so yayin aikace-aikacen.Hakanan yana taimakawa hana stucco yin faɗuwa ko faɗuwa akan filaye a tsaye.
5. Saita sarrafa lokaci:
Sarrafa lokacin saita filastar gypsum yana da mahimmanci a aikace-aikacen gine-gine.HPMC na iya daidaita lokacin saiti don samar da sassauci don saduwa da takamaiman buƙatun aikin.Wannan yana da mahimmanci musamman ga manyan ayyuka waɗanda zasu buƙaci lokutan saiti daban-daban.
6. Tasiri akan porosity:
Kasancewar HPMC yana shafar porosity na gypsum.Ƙirƙirar filastar da aka tsara da kyau tare da HPMC na iya ƙara juriya ga shigar ruwa da rage porosity, don haka ƙara ƙarfin hali da juriya ga abubuwan muhalli.
7. Daidaituwa da sauran additives:
HPMC ya dace da wasu nau'ikan abubuwan da aka saba amfani da su a cikin ƙirar gypsum.Wannan juzu'i yana ba da damar haɗaɗɗun filasta don a keɓance su don saduwa da ƙayyadaddun ƙa'idodin aiki da buƙatun aikace-aikace.
8. La'akari da muhalli:
Ana ɗaukar HPMC gabaɗaya amintacce kuma yana da alaƙa da muhalli.Ba mai guba ba ne kuma baya sakin abubuwa masu cutarwa a lokacin ko bayan plastering.Wannan ya yi dai-dai da haɓakar ƙarfafawa akan ayyukan gine-gine masu ɗorewa kuma masu dacewa da muhalli.
Hydroxypropyl methylcellulose (HPMC) yana taka muhimmiyar rawa wajen inganta aikin gypsum a aikace-aikacen gini.Riƙewar ruwan sa, haɓaka aikin aiki, mannewa, sakamako mai kauri, saita sarrafa lokaci, tasiri akan porosity, dacewa tare da sauran abubuwan ƙari da la'akari da muhalli ya sa ya zama ƙari mai mahimmanci a cikin ƙirar gypsum mai inganci.Yayin da ayyukan gine-gine ke ci gaba da haɓakawa, HPMC ya kasance babban mahimmin sinadari don inganta inganci da dorewa na filastar gypsum a cikin ayyukan gine-gine da gine-gine iri-iri.
