Basa reHFO Blowing Agents mukugadzirwa kweSpray Foam: Ongororo yekuenzanisa neHFC Blowing Agents

Furo respray rinoumbwa nezvinhu zvakasiyana-siyana, mukugadzirwa kwaro, chinhu chinoputira ndicho chimwe chezvinhu zvakakosha, chakakosha pakuumbwa kwechimiro chefuro, kufambiswa kwemafuta mumhepo uye kana chiri chigadzirwa chine hushamwari hwechisikigo zvakanyanya zvinoenderana nechinhu chinoputira. Kare, mahydrofluorocarbons (HFCS) agara achishandiswa sezvinhu zvinoputira nekuda kwekushanda kwawo kwakanyanya uye kushanduka-shanduka. Zvisinei, kunetseka nezvezvakatipoteredza kuri kukwezva pfungwa ku hydrofluoroolefins (H2O3).FOS), izvo zvinoonekwa senzira inochengetedza hupenyu.

HFCS ndeimwe yemakemikari akawanda eorganic anoumbwa nehydrogen, fluorine uye kabhoni. HFCS ikemikari inoshandiswa zvakasiyana-siyana inogona kushandiswa mukutonhodza nekufiriji, maaerosol propellants, uye kugadzira furo. Kunyangwe HFCS isingakuvadzi zvakananga munharaunda, inorongwa semagasi egreenhouse ane simba guru rekudziya kwepasi rose (GWP). Ane hupenyu hwemakore gumi nemashanu kusvika makumi maviri nemapfumbamwe mumhepo, panguva iyo anotora kupisa uye anobatsira zvakanyanya mukudziya kwepasi rose. HFCS ine simba rekubvisa ozone (ODP) re zero, iro rinobatsira pane zvinhu zvekare zvinoputika zvakaita se chlorofluorocarbons (CFCS). Zvisinei, achiri kure nekuchengetedza nharaunda, sezvo simba rawo pakuchinja kwemamiriro ekunze rinogona kusvika ka100 kupfuura carbon dioxide (CO₂).

Kuchinja kuenda kuHFOVamiririri Vanoridza

HFO chinhu chisina kuzara cheorganic chinoumbwa nehydrogen, fluorine nekabhoni, nepo HFC yakaguta. Hydrofluoroolefin (HFO) chinhu chitsva chinopfuta chakagadzirirwa kuderedza kushomeka kwezvakatipoteredza kunobatanidzwa neHFCS. Hfos dzine maatomu akafanana ehydrogen, fluorine, uye kabhoni seHFCS, asi chimiro chadzo chemakemikari chakasiyana zvakanyanya. Kusiyana neHFCS, Hfos dzine GWP yakaderera zvikuru uye ODP isina zero. Izvi zvinoreva kuti Hfos hadziparadze ozone layer uye hadzina simba rakawanda pakupisa kwenyika. Pamusoro pezvo, HFO ine hupenyu hupfupi mumhepo, izvo zvinoderedzawo kukanganisa kwayo zvakatipoteredza.

Kuenzanisa HFC neHFO Blowing Agents muSpray Foam

Panyaya yekushandiswa, basa rezvishandiso zvekuputira zveHFC neHFO mukugadzira furo rakafanana. Zvisinei, HFO ine zvakanakira zvakawanda zvinoita kuti ive sarudzo yekutanga:

Kukanganisa kwezvakatipoteredza: Kana pasina ODP uye GWP yakaderera, maHfos haana kukuvadza zvakanyanya nharaunda kupfuura HFCS.

Kuchengetedzeka: HFO haibati, haibati mhepo zvakanyanya, haina chepfu, uye haiburitse zvinhu zvinoputika zve organic (VOCs), zvichiwedzera kusimbisa hunhu hwemhepo.

Kushanda: HFO inochengetedza hunhu hwekudzivirira hunoenderana neHFC, ichiva nechokwadi chekuti furo rine hunhu hwakanaka hwekudzivirira hunopisa.

Kuedza kushandisa tekinoroji yeHFO-based spray foam ndiyo nzira yazvino yekubvisa makemikari anozivikanwa nekukuvadza ozone nemamiriro ekunze, uye kuchinja kune HFO blowing agents kunoratidza shanduko yakakura muindasitiri kuenda kune tsika dzinogara kwenguva refu. Sezvo kumanikidzwa kwemutemo kuri kuwedzera uye makambani achitsvaga mhinduro dzekuchengetedza nharaunda, HFO inogona kuve sarudzo yakajairika yekushandisa spray foam, ichivimbisa kudzivirira kunopisa kunoshanda uye kuderedza kukanganisa kwezvakatipoteredza.
