1. Yiziphi izindinganiso zokuminyana kanye ne-ILD/IFD (ukuqina), futhi umehluko phakathi kwazo uyini?
Ukuminyana (ngokuvamile 40-80 kg/m3 noma 2.5-5 PCF) kunquma ukuqina nokumelana nokwehla; uma ukuminyana kuphezulu, impilo yesevisi iba yinde. I-ILD/IFD (Indentation Load Deflection) inquma umuzwa wokuthamba noma wokuqina futhi iyindaba ehlukile ekuminyaneni, ngakho i-foam yokuminyana okuphezulu ingaba nokuthamba.
2. Ingabe izokwehla ngokushesha? Ingabe iwumsebenzi omsulwa noma inwetshiwe ngezinto zokugcwalisa? Iyini impilo yesevisi?
I-memory foam eshibhile enezinto zokugcwalisa ezengeziwe iyashintsha unomphela phakathi kwezinyanga eziyisithupha kuya konyaka, kuyilapho i-polyurethane emsulwa esezingeni eliphezulu ingahlala iminyaka eyi-7-10 noma ngisho nangaphezulu. Izinga lokubuyisela emuva lika-95-98% noma ngaphezulu ngemuva kokupakishwa nokuthuthwa ngamarola iyindlela evamile yokwamukela.
3. Ukusabalalisa ukushisa kunjani? Ingabe izwa ishisa futhi icindezelile?
Ubuthakathaka obukhulu be-memory foam evamile isakhiwo sayo esivalekile, esivame ukubamba ukushisa.
