Ngokuvamile, izinga lokushisa lokwenza ifilimu lempuphu ye-latex ephinde ihlakazeke lingaphezu kuka-0°C, kuyilapho imikhiqizo ye-EVA ivame ukuba nezinga lokushisa lokwenza ifilimu eliseduze kuka-0–5°C. Emazingeni okushisa aphansi, ukwakheka kwefilimu akunakwenzeka (noma ikhwalithi yefilimu ayinhle), okuphazamisa ukuguquguquka nokunamathela kwe-polymer mortar. Ngaphezu kwalokho, izinga lokuncibilika kwe-cellulose ether liyehla emazingeni okushisa aphansi, okuthinta ukunamathela kwe-mortar nokusebenza kwayo. Ngakho-ke, ukwakhiwa kufanele kwenziwe ngaphezu kuka-5°C ngangokunokwenzeka ukuqinisekisa ikhwalithi yephrojekthi.
I-ejenti yamandla okuqala iyinhlanganisela engathuthukisa amandla okuqala e-mortar ngaphandle kokuthinta kakhulu amandla ayo asekupheleni. Ngokusho kokwakheka kwayo kwamakhemikhali, ihlukaniswe ngezinhlobo zezinto eziphilayo nezingaphili: izinto eziphilayo zamandla okuqala zifaka i-calcium formate, i-triethanolamine, i-triisopropanolamine, i-urea, njll.; ezingaphili zifaka ama-sulfate, ama-chloride, njll.

Udinga isithasiselo esiguquguqukayo esithuthukisa ukusebenza kahle kokuphakelwa FUTHI sisheshise ukubekwa kwekhonkrithi? I-calcium formate yethu ehlanzekile kakhulu iletha kokubili - chofoza lapha ukuze uvule izixazululo ezenzelwe wena embonini yakho.
