Yadda za a inganta constructability na cellulose a kan babban zafin jiki bango a lokacin rani

A halin yanzu, ana gab da shiga rani, kuma yanayin zafi ya yi yawa, musamman a yankin arewa.Yanayin zafi yana da girma kuma iska ta bushe.Yanayin zafin jiki na bango zai iya kaiwa 60 ° C.Saboda zafin jiki, cellulose sau da yawa yana da matsaloli kamar rashin aikin gina jiki da kuma cire foda yayin ginawa.Babban dalili shi ne saboda yanayin zafi da bangon ke da shi, ruwan da aka yi amfani da shi ba shi da kyau, don haka ruwan da ke cikin kayan da aka yi da shi yana da sauri ya sha ko ya kwashe ta bango, ta yadda ba za a iya yin amfani da su ba akai-akai.Barewa da bawon suna bayyana.Yadda za a inganta riƙewar ruwa na bangon bangon foda na waje yana da hanyoyi masu zuwa:

1. Ƙara yawan adadin ether cellulose

Cellulose ether yana da kyakkyawar riƙewar ruwa, amma aikin riƙewar ruwa ba ya karuwa bayan an ƙara wani adadin cellulose ether.A lokaci guda, karuwa a cikin cellulose yana ƙara danko na putty kuma ginin ba shi da santsi.Bugu da ƙari, farashin putty yana ƙaruwa.

2. Ƙara adadin lignocellulose

Lignocellulose yana da wani tasirin riƙe ruwa.Bugu da ƙari na fiber na itace yana inganta ƙarfin riƙewar ruwa na kayan aiki, yana sa tsarin kayan aiki ya zama daidai, kuma zai iya inganta aikin aiki a lokaci guda, amma ka'idar riƙewar ruwa na lignocellulose ya bambanta da na cellulose.Yana da halayyar shayar gashi.(Gudanar da ruwa), za a sami damshi tsakanin kowace fiber, kuma lokacin da danshin da ke kewaye da fiber ya canza kuma ya ragu, za a saki damshin da ke tsakanin fibers daidai gwargwado.Lokacin buɗewa, ba sauƙin fashe ba.Duk da haka, saboda kauri na putty akan bangon waje yana da bakin ciki sosai, kauri na kowane suturar gogewa shine kawai 0.5-1mm.Lokacin da yanayin saman saman Layer da zafin iska ya yi girma sosai, aikin riƙewar ruwa ba a bayyane yake ba, kuma aikin shafa mai maimaita shi ne matsakaici.

3. Ƙara yawan adadin polymer

A kan ganuwar tare da siriri mai laushi, iska mai bushewa da zafin jiki mai girma, ƙara yawan adadin polymer yana daya daga cikin mafi kyawun hanyoyin da za a sa putty ya sake maimaita kaddarorin, amma farashin redispersible latex foda yana da inganci, babban adadin zai karu sosai. kudin putty.Hakanan zai iya taka rawa mafi kyau ta hanyar ƙara ƙaramin ƙwayar polyvinyl barasa foda, amma danko na polyvinyl barasa foda yana da girma, wanda zai shafi aikin aiki, kuma kayan sanding na putty ba shi da kyau..

4. Ƙara man shafawa na polymer

Ta hanyar gwajin, an yi la'akari da cewa shine mafi kyawun zaɓi don ƙara ƙarar mai mai girma zuwa bangon bango na waje a cikin yanayin zafi mai zafi a lokacin rani.Mai mai nasa ne na fili na polymer, kuma man shafawa na rheological galibi yana nufin haɓaka aikin gini a cikin tsarin tushen ciminti.Bude lokaci da aiki mai tsayi.Yana ƙara ƙarfin aiki da juriya na turmi, filasta, ma'ana, filasta da adhesives kuma yana hana delamination na siminti mai sarrafa kansa.Dalilin riƙe ruwa shine cewa akwai adadi mai yawa na ƙungiyoyi masu aiki na hydrophilic akan sarkar kwayoyin halitta.A cikin hali na maimaita scraping da shafi, shi ba zai rasa ruwa, yana da fice ruwa rike yi, kuma yana da thickening da thixotropy a lokaci guda, yin ginin santsi da kuma iya partially maye gurbin cellulose, amma ta farashin ne kawai cellulose ether, kuma Matsakaicin sa shine 0.1-0.2%., abu ne mai mahimmanci mai tsada, idan aka yi amfani da shi tare da cellulose ether, lignocellulose, da redispersible latex foda, sakamakon zai zama mafi kyau.
