Muri rusangi, ubushuhe bwo guhingura filime bw’ifu y’impuzu ishobora gusubira gukwiragira buri hejuru ya 0°C, mu gihe ibintu vya EVA bifise ubushuhe bwo guhingura filime buri hafi ya 0–5°C. Ku bushuhe buri hasi, uguhingura filime ntigushobora kubaho (canke uburyo bwa filime buraba bubi), ivyo bikaba bituma igiti c’ivu c’ipolymere kidashobora guhinduka no kwifatanya. Vyongeye, urugero rw’ugusenyuka kw’etere ya cellulose ruragabanuka iyo ubushuhe buri hasi, ivyo bikaba bigira ico bikoze ku kuntu iyo nkoko idashobora kwifatanya n’ivyo bikoresho be n’ukuntu ishobora gukora. Ku bw’ivyo, ubwubatsi bukwiye gukorwa hejuru ya 5°C uko bishoboka kwose kugira ngo umugambi ube mwiza.
Igikoresho co gukomeza imbere y’igihe ni ikivange gishobora gutuma ivu ry’ivu rikomeza mbere ataco rihinduye cane ku nkomezi zaryo z’inyuma. Dushingiye ku mibumbe yayo, igabanywamwo ubwoko bw’ibinyabuzima n’ibinyabuzima bitagira ubuzima: ibinyabuzima bitera inkomezi za mbere harimwo calcium formate, triétanolamine, triisopropanolamine, urea, n’ibindi; ivyo bitagira ubuzima birimwo amasulfate, ama kloride n’ibindi.

Ukeneye ikintu co kwongerako gishobora kwongereza ubushobozi bw’ibifungurwa NO kwihutisha ugushinga beton? Igikoresho cacu c’ubusuku bwinshi ca calcium formate kiratanga ivyo vyose – kanda hano kugira ngo ufungure inyishu zibereye inganda yawe.
