Sezvo mitemo yepasi rose yezvakatipoteredza ichinyanya kusimba uye kuchengetedzeka kuri kudiwa, vagadziri vemafuro epolyurethane vari kushandisa nzira dzekurima uye dzinoshanda zviri nani. Mhando mbiri huru dzemafuro epolyurethane spray foam dziri kutonga indasitiri iyi parizvino:furo repurasitiki rinopfapfaidzwa nemvurauyemasisitimu ekufema ehydrofluoroolefin (HFO)Sisitimu yega yega ine zvinhu zvakasiyana, mabhenefiti, nematambudziko. Chinyorwa chino chichaongorora kusiyana kwadzo uye chicharatidza kukosha kwezvinhu zvinokonzeresa, zvakaita seMXC-70, izvo zvinogona kuvandudza mashandiro efuro, kunyanya mukushandiswa kwefuro rinopfurwa nemvura.
Kunzwisisa Masisitimu ePolyurethane Spray Foam Anopfurwa Nemvura
Masisitimu epurasitiki inopfapfaidzwa nemvura anoshandisa mvura sechinhu chinopfuta pamwe chete kugadzira kabhoni dhayiokisaidhi (CO₂) nekuita zvinopesana neisocyanates. CO₂ iyi inoshanda sechinhu chikuru chinopfuta, ichikudza chimiro chefuro.
Mabhenefiti eFuro reSpray Rinopfurwa Nemvura:
- Zvine Rubatsiro Kunharaunda:Sezvo mvura isingabatsire pakuderedza ozone layer kana kupisa kwepasi rose, hurongwa uhwu hunoonekwa senzira isingakuvadzi nharaunda.
- Inodhura Zvishoma:Mvura inowanikwa zvakanyanya uye yakachipa kana tichienzanisa nezvinhu zvinofefetera zvakagadzirwa.
- Kutevedzera Mutemo:Inozadzisa mitemo yezvakatipoteredza inorambidza kushandiswa kwezvinhu zvinopisa zvine simba guru reGWP (global warming potential).
- Kunamira Kwakawedzerwa:Maitiro acho anogadzira chisungo chakasimba pakati pema substrates, zvichiita kuti zvive zvakakodzera kushandiswa pakuvaka.
Matambudziko eFuro reSpray rinopfurwa nemvura:
- MaR-Values Akaderera:Mafuro anoputirwa nemvura anowanzova nekushanda kwakaderera kwekudzivirira kupisa (R-values) kupfuura mafuro ane HFO.
- Kuwedzera Kupenya:Furo rinogona kuomarara uye kupwanyika nekufamba kwenguva, zvichikanganisa kugara kwenguva refu.
- Kunzwa Kwemvura Yakawanda:Mashandiro anogona kuchinja kana hunyoro hwacho huchikwira, zvichireva kuti mvura yacho inogadzirwa zvakanaka uye inogadziriswa.
Kukwira kweHFO-Based Spray Foam Systems
Masisitimu epurasitiki anopfapfaidza eHFO anoshandisa hydrofluoroolefins (HFOs) semushonga wekupfuudza wechizvarwa chinotevera. Makemikoro aya anopa simba rekudzivirira kupisa uku achichengetedza nharaunda isina simba.
Mabhenefiti eHFO Spray Foam:
- MaR-Values Akakwirira:Kudzivirira kupisa kuri nani pa inch imwe neimwe yeukobvu, zvichiita kuti ive sarudzo yakanaka yekudzivirira kupisa kunochengetedza simba.
- Utsi Hunobuda Mumhepo Hwakaderera:HFOs dzine GWP yakaderera zvikuru (kazhinji isingasviki 1), zvichideredza zvakanyanya kukanganisa nharaunda.
-Hunhu Hwakanaka hweFoam:Mafuro anobva kuHFO anogadzira chimiro chemasero chakanyatsonaka uye chakafanana, izvo zvinovandudza hunhu hwemakanika uye kugara kwenguva refu.
-Kuderedzwa kweShrinkage:Maumbirwo emasero akavharwa emafuro eHFO anoderedza kuderera kwesimba, zvichiita kuti ashande kwenguva refu.
Matambudziko eHFO Spray Foams:
-Mutengo Wakakwira:Zvinhu zvisina kugadzirwa uye mafomura zvinowanzo kudhura kupfuura masisitimu anoputirwa nemvura.
-Kunzwisisa kweMagadzirirwo:Kusarudza nemazvo zvinhu zvinokonzeresa kucheneswa kwemasero nemasurfactants kunodiwa kuti pave nekusimbaradzwa uye kushanda zvakanaka kwemasero.
Kusarudzwa kweCatalyst: Basa reMXC-70muMasisitimu Anopfurwa Nemvura
Chimwe chezvinetso zvikuru zvema "polyurethane foam" anoputirwa nemvura ndechekuwanakupora kwakapfava uye kunamiraukuwo uchideredza hwema hwema hweamine husingadiwe. Apa ndipo panowanikwaMXC-70ine basa guru.
Sei Uchifanira Kusarudza MXC-70 Yemasystem Anoputika Nemvura?
-Fomura Yekunhuhwirira Kushoma:Kusiyana nezvinokonzeresa amine zvechinyakare, MXC-70 inoderedza kunhuhwirira zvakanyanya, zvichiita kuti ive yakakodzera kushandiswa mukati memuviri.
-Nhoroondo yeSmooth Rise:Inovimbisa kuti furo rinobuda zvakanaka uye kuti furo rinokwira zvakanaka, zvichidzivirira kudonha kwefuro uye zvikanganiso.
-Kurapa Kwakavandudzwa Pamusoro:Inovandudza maitiro ekugadzika, zvichiita kuti furo rive rakafanana uye rakasimba.
-Kunamira Kwakanaka:Inowedzera simba rekubatanidza furo ne substrate, izvo zvakakosha mukuvaka nekushandisa insulation.
-Kuenderana neMasisitimu Akavakirwa Pamvura:Yakagadzirirwa kushanda nemazvo nemafuro epolyurethane ane CO₂ blown.
Mhedziso
Masisitimu ese ari maviri epurasitiki inopfapfaidzwa nemvura uye HFO ane mabhenefiti akasiyana ekudzivirira kupisa uye zvinodiwa pakugadzira.Masisitimu eHFOchipokushanda zvakanaka kwekudzivirira kupisa, furo rinofuridzwa nemvurainoramba iri sarudzo isingadhuri uye isingakuvadzi nharaunda. Kusarudza chinhu chinobatsira pakugadzira furo kwakakosha kuti ugone kushandisa furo zvakanaka, uyeMXC-70isarudzo yakakura yemafomura anofuridzwa nemvuranekunhuhwirira kushoma, kupora kwakapfava, uye kunamira kwakasimba.
Kune vagadziri vari kutsvaga kuvandudza masisitimu avo epolyurethane foam, kusarudza catalyst chaiyo kunogona kuita mutsauko mukuru.Tibatei nhasi kuti muzive zvakawanda nezve MXC-70 uye kuti ingavandudza sei mafoam enyu e polyurethane spray.
