1. Umgubo welatex ophinda uhlakazwe
Lo mbandela wokunkcenkceshela umlomo yipolymer ekhethekileyo ephezulu yemolekyuli, eyenziwa ibe ngumgubo emva kokutshiza kokumisa.Emva kokunxibelelana namanzi, le powder ingaba yi-emulsion kwakhona, kwaye ineempawu ezifanayo njenge-emulsion.Emva kokuba amanzi aphuke, angenza ifilimu.Ifilimu inokuguquguquka okuphezulu, ukumelana nemozulu ephezulu, kwaye ibonisa ukunamathela okuphezulu kwii-substrates ezahlukeneyo.
Ke ngoko, yinto eyimfuneko ekrwada kudaka oluxutyiweyo, olunokuphucula ukusebenza, ukwandisa amandla, ukuphucula udaka lodaka olomileyo kwii-substrates ezahlukeneyo, ukuphucula ukuguquguquka, amandla oxinzelelo, kunye nokumelana nodaka lodaka olomileyo.Ukongeza, ukuba ixutywe kunye ne-hydrophobic latex powder, inokwenza udaka olomileyo lungabi namanzi.
2. Iselulosi
I-Cellulose ene-viscosities eyahlukeneyo ineendlela ezahlukeneyo zokusetyenziswa.I-Cellulose ingasetyenziselwa kwi-low-grade putty powder kwiindonga zangaphakathi, ezinokutyebisa ukugcinwa kwamanzi kunye nokunyusa umgangatho.Izinzile ngokwekhemikhali, inokuthintela ukubola, inesiphumo esihle sokugcina amanzi, kwaye ayichatshazelwa lutshintsho kwixabiso le-pH.Ingasetyenziswa ukusuka kwi-50,000 ukuya kwi-200,000 viscosities.Amandla ebhondi ahambelana ngokungafaniyo, i-viscosity iphezulu, kodwa amandla amancinci, ngokubanzi phakathi kwe-50,000 kunye ne-100,000.Ikakhulu kukunyusa umgangatho kunye nokwakhiwa kodaka lomgubo olomileyo, kunye nokunciphisa ngokufanelekileyo umthamo wesamente.
Ukongeza, udaka lwesamente lunexesha lokuqina.Ngexesha lokuqiniswa, ukugcinwa kwezandla kuyafuneka ukuze kugcinwe kumanzi.Ngenxa yokugcinwa kwamanzi kwi-cellulose, umswakama ofunekayo ekuqinisweni komdaka unokufumaneka ekugcinweni kwamanzi kwi-cellulose, ngoko unokuqina ngaphandle kokugcinwa okukhethekileyo.
3. Lignin
Indima ye-lignin kwi-powder mortar eyomileyo kukumelana nokuqhekeka.Xa i-lignin ihlakazwa emanzini, ikhona ngendlela yeefiber ezimfutshane.Ngokomzekelo, xa ukwakhiwa kweendonga ngomhlaba kwiindawo zasekhaya, iindiza zengqolowa kunye ne-rice straw zongezwa ukukhusela ukuqhekeka.Xa usebenzisa i-lignin, kungcono ukhethe izinto ezicocekileyo ngaphandle kokungcola.Xa uchonga i-lignin, unokujika i-lignin ukuze ubone ukuba kukho uthuli olusele.Ubuninzi be powder, bubi kakhulu umgangatho.Okanye ubeke i-lignin encinci emanzini kwaye ukhangele, ngcono ukusabalalisa, bhetele umgangatho, oku kuthetha ukuba ukuba yongezwa kwi-powder mortar, kulula ukusabalalisa kwaye ayiyi kwenza ibhola.
4. Inorganic bonding imathiriyeli
I-Ash calcium powder yi-calcium hydroxide, into eqhelekileyo esetyenziswa kwi-inorganic bonding.Ikakhulu idlala indima edibeneyo kwi-putty powder ukufezekisa imiphumo yokungangeni kwamanzi kunye nokumelana namanzi.Kukho iindawo ezininzi ezivelisa i-limestone e-China, ngoko ke ukuveliswa kwe-lime calcium powder kuqhelekileyo.Nangona kunjalo, kwezinye iindawo, i-putty mortar eyenziwe nge-lime calcium powder eveliswayo inokutshisa ulusu lwezandla ngexesha lokwakhiwa.Ukusabela kwe-exothermic, ngoko idrafti ye-ash calcium powder ine-alkaline kakhulu.Idrafti enkulu, ingazinzi ngakumbi, kwaye kulula ukuyiqhekeza xa ikrwela eludongeni.Sifuna izinto eziphathekayo ezinothuli oluzinzile lwe-calcium ash powder, ene-drafti encinci, ubumhlophe obuhle, kwaye ayiguquli izandla.
