Iimveliso Iinkcukacha
I-HFC eps iqulunqwe ngamaso amancinci amnyama e-polystyrene (EPS) equlethe i-ejenti yokuvuthela, eyenza ukuba i-expandable.Ikhemikhali enqabileyo ivelisa le nto ikhethekileyo, ecutshungulwa ngabavelisi be-foam kwizinto zokugquma ukwenzela uluhlu olubanzi lwezicelo ezahlukeneyo.
I-HFC eps luphuculo oluyilayo lwe-eps yakudala yokugquma kwaye sele iluphawu olomeleleyo ukusukela ngo-2012, ibonelela ngazo zonke izibonelelo zoqobo:
Iiparamitha eziphambili Phakathi kwegraphite kunye ne-eps eqhelekileyo yokubuyisela umlilo
| Ukuthelekisa | Ibakala legraphite (HFC) | Isithinteli somlilo esimhlophe (F) |
| Ukukala komlilo | B1 | B2 |
| Isicelo | Ukufakwa eludongeni, isandi I-Insulation, i-Fireproof | I-Insulation eludongeni, ifriji
Ugcino |
| Ubuninzi (g/l) | 14-35 | 12-30 |
| I-Coefficient of thermal ukuqhuba w/(mk) | ≤0.032 | ≤0.041 |
| Amandla acinezelayo (mpa) | ≥0.10 | ≥0.06 |
| Ukufunxwa kwamanzi | ≤2% | ≤2% |
| Isalathiso seoksijini | ≥30 | ≥30 |
Ukusebenza okungcono kwe-HFC kwi-thermal conductivity
Iziphumo zokugquma eziphuculwe kakhulu zinokufikelelwa nge-HFC, ngakumbi ngoxinaniso lwesambuku esisezantsi kakhulu.Umzobo ubonisa ukuba imathiriyeli yokugquma i-HFC enoxinano lwe-bulk ye-15 kg/m³ umzekelo ifikelela kwi-thermal conductivity ye-0.032 W/(m·K).Kwi-EPS eqhelekileyo ene-bulk density efanayo, i-thermal conductivity yi-0.037 W/(m·K).

ISICELO
I-HFC eps inokudityaniswa kwedangatye okugqwesileyo, ukusetyenzwa ngokulula ngaphandle kothuli kwaye akukho bungozi eluswini, ngaphandle koko, inokuphinda iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde ibe nebhodi engqindilili kunebhodi etyebileyo kunee-eps eziqhelekileyo, inciphisa iindleko kakhulu, ngaphezu koko, inokwandisa ixesha lokuphila isakhiwo.
