Umatshini wokuvavanya ubulukhuni bokugoba kwesponji

Umatshini wokuvavanya ubulukhuni bokugoba i-sponge ukwabizwa ngokuba yi-sponge, umatshini wokuvavanya ubulukhuni bokugoba i-foam, i-tensile metallic kunye ne-non-metallic, izixhobo ze-polymer, ucinezelo, ukugoba, ukufumanisa ukudinwa komjikelo ophantsi kunye nezinye iiprojekthi zinokuhambelana neemfuno zemveliso yabathengi ngokwe-GB, ISO, ASTM, JIS, EN kunye neminye imigangatho yokulungiselela, ukuze ibethe ngokuzenzekelayo uvavanyo olukhulu, amandla okwaphuka, amandla okukhupha, amandla okudonsa, amandla okucindezela, amandla okuguquguquka, i-modulus ye-elastic, i-elongation, uxinzelelo oluqhubekayo lobude, i-elongation kunye nezinye iiparameter ezinikwe uxinzelelo.
