Iimortar ezizilinganisayo zixhomekeke kubunzima bazo ukuze zenze isiseko esithe tyaba, esigudileyo nesiqinileyo kwi-substrate, zivumela ezinye izinto ukuba zibekwe okanye zibotshelelwe, ngelixa zifikelela kwiindawo ezinkulu nezisebenzayo zokwakha. Ke ngoko, ukutyibilika okuphezulu luphawu olubaluleke kakhulu lwemortar ezilinganisayoyo. Kufuneka kwakhona ibe nomlinganiselo othile wokugcina amanzi kunye namandla okubopha, ingatyibiliki kwaye ihlukane, kwaye ibe nobushushu obuphantsi kwaye ingabi na-adiabatic.
Udaka oluzilinganiselayo ngokubanzi lufuna ukutyibilika okuhle, kodwa ukuhamba kodaka lwesamente ngokuqhelekileyo yi-10-12cm kuphela; i-cellulose ether yeyona nto iphambili exutyiweyo, nangona isixa esongeziweyo siphantsi kakhulu, sinokuphucula kakhulu ukusebenza kodaka, nto leyo enokuphucula ukuhambelana kodaka, ukusebenza kakuhle, ukusebenza kokubopha kunye nokusebenza kokugcina amanzi. Inendima ebaluleke kakhulu kwicandelo lodaka oluxutyiweyo.
1 Ukufuma
I-Cellulose ether inefuthe elikhulu ekugcinweni kwamanzi, ukuhambelana kunye nokusebenza kakuhle kwe-mortar. Ingakumbi njenge-mortar ezilinganisa ngokwazo, ukutyibilika yenye yezona zibonakaliso ziphambili zokuvavanya ukusebenza kwe-self-leveling. Ukutyibilika kwe-mortar kunokulungiswa ngokutshintsha ubungakanani be-cellulose ether phantsi kwesiseko sokuqinisekisa ukwakheka okuqhelekileyo kwe-mortar. Umxholo ophezulu kakhulu uya kunciphisa ukutyibilika kwe-mortar, ngoko ke, ubungakanani be-cellulose ether kufuneka bulawulwe ngaphakathi koluhlu olufanelekileyo.
2 Ukugcinwa kwamanzi
Udaka olugcina amanzi luphawu olubalulekileyo lokuzinza kwezinto zangaphakathi zodaka lwesamente. Ukuze izinto zejeli zisebenze ngokupheleleyo, inani elifanelekileyo le-cellulose ether lingasetyenziswa ixesha elide ukugcina amanzi kwidaka. Ngokubanzi, njengoko inani le-cellulose ether lisanda, ukugcinwa kwamanzi kwidaka nako kuyanda. Ukongeza, ukuqina kwe-cellulose ether kunefuthe elikhulu ekugcinweni kwamanzi kwidaka; okukhona i-viscosity iphezulu, kokukhona ukugcinwa kwamanzi kuyanda.
3 Ixesha lokuseta
I-Cellulose ether inefuthe lokuthintela i-mortar. Njengoko i-cellulose ether isanda, ixesha lokuseta i-mortar liya kwanda. Kwaye xa i-cellulose ether iphezulu, isiphumo sokuqala se-compound hydration hysteresis yesamente sibonakala ngakumbi.
4 Amandla okugobeka kunye namandla okucinezela
Ngokubanzi, amandla yenye yezona ndlela zibalulekileyo zokuvavanya umxube we-cementitious cementitious material. Amandla okuxinzelela kunye namandla okugoba kwe-mortar aya kuncipha xa umxholo we-cellulose ether usanda.
