Iyoindasitiri yefuro repfapfaidzoyave ichichinja zvakanyanya zvichienderana nemitemo mitsva yakanangana nekuderedza kukanganisa kwemakemikari emaindasitiri. Chinangwa chikuru chemitemo iyi kubvisa mahydrofluorocarbons (HFCs) ane njodzi panzvimbo pekushandisa dzimwe nzira dzisingakuvadzi nharaunda dzakadai sehydrofluoroolefin (HFO) blowing agents. Kana uri muindasitiri yespray foam, zvakakosha kuve nechokwadi chekuti mishonga yako yefuro inotevedzera mitemo iyi kudzivirira kurangwa uye kubatsira mune ramangwana rakasimba.
Kunzwisisa Kuchinja kubva kuHFC kuenda kuHFOs
Muna 2021, United States yakaisa mitemo yakaoma yekubvisa maHFC, makemikari anoumbwa nemaatomu efluorine nehydrogen. MaHFC ave achishandiswa zvakanyanya muzvinhu zvinoputira zvinonamira padenga remafuro uye zvinhu zvinodzivirira kupisa nekuda kwekudzivirira kupisa kwakanyanya (R-value). Zvisinei, kugona kwavo kupisa kwepasi rose (GWP) uye simba ravo rekubvisa ozone zvakakonzera kunetseka kwezvakatipoteredza.
MaHFC anowanikwawo muma air conditioner uye mafiriji, zvichibatsira zvikuru mukuburitswa kwemagasi egreenhouse. Sechikamu chekuedza kukuru kuderedza shanduko yemamiriro ekunze, maindasitiri ikozvino anofanirwa kuchinjira kune ma HFO blowing agents. Ma HFO, kana kuti hydrofluoroolefins, chizvarwa chitsva chema blowing agents anopa mabhenefiti akati wandei ezvakatipoteredza:
1. Hazvibatike: MaHFO haabatike, zvichiita kuti pave nekuchengetedzeka panguva yekuisa nekuchengetedza.
2. Kusava Nekuora KweOzone (ODP): Kusiyana nemaHFC, maHFO haaderedzi ozone layer, zvichiita kuti ive sarudzo inogara kwenguva refu.
3. Kudzikira Kwepasi Pose (GWP): MaHFO ane GWP yakaderera zvikuru kana tichienzanisa nemaHFC, zvichideredza kukanganisa kwezvakatipoteredza.
Mabhenefiti eHFO Blowing Agents muFuro repfapfaidzo
Zvinhu zvinoputira HFO imhando yechinhu chinoputira chinobvisa kupisa mumuviri, zvinoreva kuti chinotora kupisa panguva yekuputira furo. Izvi zvinoita kuti furo rive diki, zvichiwedzera chitarisiko uye hunhu hwemuviri hwefuro. Hunhu uhwu hunoita kuti HFO dzinyanye kukodzera kushandiswa kunoda kushanda zvakanaka kwekudzivirira kupisa.
Pamusoro pekubatsira kwazvinoita zvakatipoteredza, zvinhu zvinofefetera zveHFO zvinobatsira mukudzivirira kupisa (R-value), zvichibatsira zvivakwa kuchengetedza simba rakawanda. Sezvo indasitiri yekuvaka ichinyanya kukoshesa kugara kwenguva refu, kushandiswa kwetekinoroji yeHFO-based blowing agents kunomiririra danho rakakosha mukuderedza kukanganisa kwayo kupisa kwenyika.
Kuve nechokwadi chekutevedzera Mitemo
Kuti utevedzere mitemo yazvino, zvakakosha kuongorora zvinhu zvinoputira zvinoshandiswa muzvigadzirwa zvako zvespray foam. Kuchinja kuita zvinhu zvinoputira HFO hakungobatsiri chete kuti usvike pazvinodiwa nemitemo asiwo kunoisa bhizinesi rako padanho rekutungamira mukuita zvinhu zvinogara kwenguva refu.
Heano mamwe matanho ekuona kuti zvinotevedzwa:
- Gara Uchiziva: Ramba uchiziva nezvemitemo iripo uye mitemo yeindasitiri ine chekuita nemidziyo inoburitsa zvinhu.
- Ongorora Zvigadzirwa Zvako: Ita ongororo yakakwana yezvigadzirwa zvako zviripo kuti uone chero zvinoshandisa maHFC.
- Chinja kuenda kuHFOs: Chinja zvishoma nezvishoma kuenda kuHFO blowing agents, uchishandisa zvakanakira zvakatipoteredza uye mashandiro azvo.
- Dzidzisai Chikwata Chenyu: Dzidzisai vashandi venyu nezvemabhenefiti uye nzira dzekushandisa mishonga yeHFO blowing kuti muve nechokwadi chekuti shanduko yacho inofambira mberi zvakanaka.
Nekushandisa mishonga inofefetera yeHFO, unogona kuva nechokwadi chekuti zvigadzirwa zvako zvespray foam zvinotevedzera mitemo uku uchibatsira pakuchengetedza hutano hwakanaka. Maitiro aya ekugadzirisa haangoderedzi njodzi dzemutemo chete asiwo anobatanidza bhizinesi rako nekuwedzera kuri kuda kwemhinduro dzekuvaka dzinogara kwenguva refu.
