Donfoam 822PIR HCFC-141B base musanganiswa polyols inoenderera PIR block furo
NHUNGAMIDZO
DonFoam 822/PIR imhando yekusanganisa polyols ine hcfc-141b inopupuma furo, ine polyol seyakanyanya mbishi, yakasanganiswa neyakakosha yekubatsira mumiriri, yakakodzera kuvharwa kwekuvaka, kutakurwa, goko uye zvimwe zvigadzirwa .Ichi chinyorwa chakagadzirwa zvakanyanya for continuous line .Chigadzirwa che polyurethane chakagadzirirwa nekuchigadzirisa ne isocyanate chine zvinotevera zvakanakira:
1. Foam ine simba rakafanana uye kugadzikana kwedimensional kumativi ose
2. Zvigadzirwa zvefuro zvinogona kutemwa mumhando dzakasiyana maererano nezvinodiwa zvechigadzirwa
3. Yakanakisa thermal insulation performance
