Imininingwane Yemikhiqizo
I-HFC eps yakhiwe ngobuhlalu obuncane obumnyama be-polystyrene (EPS) equkethe i-ejenti ephephethayo, eyenza inwebeke.Ikhemikhali ethambile ikhiqiza le nto eyingqayizivele, ecutshungulwa abakhiqizi begwebu benze izinto ezivikelayo zezinhlelo eziningi ezahlukene.
I-HFC eps iyisithuthukisi esisha se-insulation classic eps futhi isivele ingumkhiqizo oqinile kusukela ngo-2012, enikeza zonke izinzuzo zeyokuqala:
Imingcele eyinhloko Phakathi kwe-graphite kanye nama-eps avamile avimbela umlilo
| Ukuqhathanisa | I-graphite yebanga (HFC) | I-white retardant (F) |
| Isilinganiso somlilo | B1 | B2 |
| Isicelo | I-Wall Insulation, Umsindo I-Insulation, i-Fireproof | I-Wall Insulation, Isiqandisi
Isitoreji |
| Ukuminyana (g/l) | 14-35 | 12-30 |
| I-coefficient of thermal conductivity w/(mk) | ≤0.032 | ≤0.041 |
| Amandla acindezelayo (mpa) | ≥0.10 | ≥0.06 |
| Ukumuncwa kwamanzi | ≤2% | ≤2% |
| I-Oxygen Index | ≥30 | ≥30 |
Ukusebenza okungcono kwe-HFC ku-thermal conductivity
Imiphumela yokuvikela ethuthuke kakhulu ingafinyelelwa nge-HFC, ikakhulukazi ngokuminyana kwenqwaba ephansi kakhulu. Umdwebo ubonisa ukuthi izinto ezivikelayo ze-HFC ezinenqwaba yokuminyana okungu-15 kg/m³ ngokwesibonelo zithola ukuhanjiswa kwe-thermal okungu-0.032 W/(m·K). Ku-EPS evamile enokuminyana kwenqwaba efanayo, ukuqhutshwa kwe-thermal kungu-0.037 W/(m·K).
Ishidi lokucaciswa komkhiqizo
| Ukucaciswa. | I-Diam. Ibanga (mm) | Izikhathi | Ukuminyana (g/L) | I-BlowingAgent (%) | Umswakama (%) | I-OxygenIndex. (%) |
| I-HFC-301 | 1.00-1.60 | 55-70 | 14-18 | 5.5-6.8 | ≤2% | ≥30 |
| I-HFC-302 | 0.85-1.25 | 50-60 | 16-20 | |||
| I-HFC-303 | 0.70-0.90 | 40-55 | 18-25 | |||
| I-HFC-401 | 0.50-0.80 | 35-45 | 22-30 | |||
| I-HFC-501 | 0.40-0.60 | 30-40 | 25-35 |
Izithombe zomkhiqizo
ISICELO
I-HFC eps inokubambezeleka kwelangabi okuhle kakhulu, ukucutshungulwa kalula ngaphandle kothuli futhi okungeyona ingozi esikhumbeni, ngaphandle kwalokho, ingaphinda ifinyelele umphumela ofanayo wokufaka ngebhodi eliwugqinsi kunama-eps ajwayelekile, yehlise izindleko kakhulu, ngaphezu kwalokho, inganweba isikhathi sokuphila isakhiwo.
