⑵ Ukugcinwa kwamanzi aphezulu, ukwandisa ixesha lokugcinwa kodaka, ukuphucula ukusebenza kakuhle, kunye nokuququzelela i-hydration kunye nokuqina kodaka ukuvelisa amandla aphezulu omatshini.
⑶ Lawula ukungaguquguquki kodaka ukwenza umgangatho ofanelekileyo wokugquma.
3. Udaka lweMasonry
⑴ Yandisa ukunamathela ngomphezulu we-masonry, phucula ugcino lwamanzi, kwaye uphucule ukomelela kodaka.
⑵ Ukuphucula i-lubricity kunye neplastiki, kunye nokuphucula ukwakhiwa;udaka oluphuculwe yi-cellulose ether kulula ukwakha, lugcina ixesha lokwakha kunye nokunciphisa iindleko zokwakha.
⑶ I-ether ye-cellulose egcina amanzi ephezulu kakhulu, ifanele izitena ezifunxa amanzi amaninzi.
4. Iphaneli yokugcwalisa ngokudibeneyo
⑴Ugcino lwamanzi olugqwesileyo, ukwandisa ixesha lokuvula kunye nokuphucula ukusebenza kakuhle.I-lubricant ephezulu, kulula ukuyixuba.⑵ Phucula ukuxhathisa ukushwabana kunye nokumelana nokuqhekeka, phucula umgangatho wokwambathisa.⑶ Phucula ukunamathela komphezulu wokudibanisa kwaye unikeze ukuthungwa okugudileyo kunye nokugudileyo.
5. I-Adhesive yeThayile ⑴Kulula ukomisa izithako zomxube, akukho maqhuma, ukwandisa isantya sosetyenziso, phucula ukusebenza kolwakhiwo, konga ixesha lokusebenza kunye nokunciphisa iindleko zokusebenza.⑵ Ngokwandisa ixesha lokuvula, ukusebenza kakuhle kwethayili kunokuphuculwa kwaye umphumo obalaseleyo wokubambelela unokunikezelwa.
6. Izixhobo zomgangatho ozimele ⑴ zibonelela nge-viscosity kwaye zingasetyenziswa njengezongezo ezichasene nentlenga.⑵Ukuphucula ukumpompa kwamanzi kunye nokuphucula ukusebenza kakuhle kokugalela umhlaba.⑶ Lawula ukugcinwa kwamanzi kunye nokushwabana, ukunciphisa iintanda kunye nokushwabana komhlaba.
7. Ipeyinti esekwe emanzini ⑴Thintela imvula eqinileyo kwaye wandise ubomi besikhongozeli semveliso.Uzinzo oluphezulu lwebhayoloji, ukuhambelana okugqwesileyo kunye namanye amacandelo.⑵ Phucula ulwelo olumanzi, bonelela ngokuchasa ukuchaphaza okuhle, ukuchasa ukuthoba kunye neempawu zomgangatho, kwaye uqinisekise ukugqitywa komphezulu okugqwesileyo.
8. Iphepha lodonga ⑴ Yinyibilike ngokukhawuleza ngaphandle kwamaqhuma, alungele ukuxuba.⑵ ukunika amandla ebhondi ephezulu.
9. Ibhodi yesamente eyongeziweyo (1) inokubambisana okuphezulu kunye ne-lubricity, kwaye iphucula ubuchule beemveliso ezikhutshiweyo.⑵ Phucula amandla aluhlaza, ukhuthaze amanzi kunye nesiphumo sokunyanga, kunye nokwandisa isivuno.
10. Iimveliso ze-HPMC ezinikezelwe kwimveliso yodaka esele ixutyiwe ye-HPMC ezinikele kwidaka esele ixutyiwe inokugcinwa kwamanzi ngcono kwidaka esele ixutyiwe kuneemveliso eziqhelekileyo, iqinisekisa ukugalelwa okwaneleyo kwezixhobo ze-cementitious ze-inorganic, ukuthintela ngokubonakalayo ukunciphisa amandla ebhondi okubangelwa ukomiswa ngokugqithisileyo. , kunye Nokuqhekeka okubangelwa kukomisa ukushwabana.HPMC kwakhona isiphumo umoya-entraining ethile.Imveliso ye-HPMC esetyenziselwa ngokukhethekileyo udaka oluxutywe olulungeleyo lunomlinganiselo ofanelekileyo we-air-entrained, iyunifomu kunye namaqamza amancinci omoya, anokuphucula amandla kunye nokugudiswa kodaka oluxutywe ngokufanelekileyo.Imveliso ye-HPMC esetyenziselwa ngokukhethekileyo udaka oluxutywe olulungeleyo lunempembelelo ethile yokunciphisa, enokwandisa ixesha lokuvula udaka oluxutywe ngokufanelekileyo kunye nokunciphisa ubunzima bokwakha.
