Incazelo Yomkhiqizo:

Kubasebenzisi abancane bemishini yeqhwa ethengiswayo namakhasimende angasebenzisa iqhwa ngezikhathi ezivamile emini, abadingi ukuletha uhlelo lwesiqandisi ekamelweni labo lokugcina iqhwa.

Egumbini elikhulu lokugcina iqhwa, amayunithi esiqandisi ayadingeka ukuze ahlale izinga lokushisa langaphakathi lisuswe ukuze iqhwa likwazi ukugcinwa ngaphakathi ngaphandle kokuncibilika isikhathi eside.

Amakamelo eqhwa asetshenziselwa ukulondolozwa kweqhwa leqhwa, i-block ice, amashubhu eqhwa afakwe esikhwameni nokunye.

Izici:

1. Ugqinsi lwebhodi lokugcina elibandayo lungaphezu kuka-10 cm

2. Igwebu le-polyurethane, i-insulation

3. impahla yangaphakathi ingakhetha insimbi engagqwali 304 noma galvanization

4. Ngaphandle kweyunithi yesiqandisi, iqhwa lingagcinwa ngaphakathi ngaphandle kokuncibilika izinsuku ezingu-1-3.

5. Ngeyunithi yesiqandisi, iqhwa lingagcinwa ngaphakathi isikhathi eside.
