Isiteshi sokudonsa amanzi esinama-Grates Ensimbi Engagqwali
Incazelo Yomkhiqizo I-Drainage edge Polymer Concrete: Ilula, Iqinile futhi Ayizweli.Amayunithi esiteshi akhiwe ngokhonkolo we-polymer.I-polyester resin, esetshenziswa njenge-ejenti ebophayo, kanye nenhlanganisela yamaminerali yenza ukhonkolo we-polyester ube yimpahla yokwakha engacindezeli ngokwedlulele;hhayi kuphela ekwazi ukumelana nemithwalo esindayo, kodwa futhi isikhathi eside ngokwedlulele futhi ihlala isikhathi eside.Ukhonkolo we-polymer awushi, ufaka isithwathwa futhi uyamelana nesimo sezulu kanye nama-asidi ahlanjululwe kanye nama-alkali.I-stainless s...
