Sezvo polyurethane rigid foam (PU rigid foam) ine hunhu hwehuremu huremu, yakanaka yekupisa yekumisa mhedzisiro, kuvaka kuri nyore, nezvimwewo, uye zvakare ine hunhu hwakanakisa senge kuvharwa kweruzha, kuvhunduka kwekutya, kuvharisa kwemagetsi, kupikisa kupisa, kutonhora, kunyungudutsa. kuramba, nezvimwewo, yakashandiswa zvakanyanya kumba nekune dzimwe nyika.Mumuchadenga, kuvaka ngarava, peturu, midziyo yemagetsi, mota, chikafu uye mamwe maindasitiri.
Iko kushandiswa kukuru kwePU rigid foam ndeaya anotevera:
1. Midziyo yefiriji yemidziyo yemumba uye maindasitiri ezvekudya
Mafirijiuye mafiriza anoshandisa PU rigid foam sezvo iyo insulation layer ine yakatetepa insulation layer.Pasi pezviyero zvakafanana zvekunze, vhoriyamu inoshanda yakakura zvakanyanya kupfuura kana zvimwe zvishandiswa zvinoshandiswa seyadzisiro yekudzivirira, uye huremu hwemudziyo hunoderedzwa zvakare.
Maheater emvura emudzimba emagetsi, solar water heaters, uye doro keg interlayers zvinowanzo shandisa rigid polyurethane foam insulation materials.PU rigid foam inoshandiswawo mukugadzira inotakurika incubators yekutakura zvipenyu zvigadzirwa, mishonga uye chikafu chinoda kupisa kwekupisa uye kuchengetedza.
2.Industrial midziyo uyepipelineinsulation
Matangi ekuchengetedza uyemapaipimidziyo inowanzoshandiswa mukugadzirwa kwemaindasitiri, uye inoshandiswa zvakanyanya mupetroleum, gasi rechisikigo, kunatsa mafuta, indasitiri yemakemikari, indasitiri yemwenje uye mamwe maindasitiri.Chimiro chetangi rekuchengetedza chakatenderera kana cylindrical, uye iyo PU yakaoma furo inogona kugadzirwa nekupfapfaidza, kudurura nekunamira furo rakagadzirwa.Sezvo apipelinethermal insulation material, inoshandiswa zvakanyanya pakupisa kwemafuta epombi mukutakura mafuta asina kuchenamapaipiuye petrochemical industries, uye yakabudirira kutsiva zvinhu nekunyura kwemvura yakakwira senge perlite.
3. Zvinhu zvekuvaka
Kuvaka dzimba ndeimwe yeakanyanya kukosha maficha ekushandisa ePU rigid foam.MuChina, furo rakaomarara rave richizivikanwa nekuda kwekupisa kwemafuta uye kudzivirira mvura kwematenga edzimba uye ehofisi zvivakwa,kuvaka Insulation zvinhu, uye thermal insulation materials forimba inotonhora, zviyo zvezviyo, nezvimwewo. Iyo yakapfapfaidzwa yakaoma furo inoshandiswa padenga, uye denga rekudzivirira rinowedzerwa, iro rine maitiro maviri ekudzivirira kupisa uye kudzivirira mvura.
Yakasimba polyurethanesandwich panelsanoshandiswa zvakanyanya muzvirimwa zvemaindasitiri, matura, nhandare, dzimba dzekugara, mavillas, prefab dzimba uye zvakasanganiswa.imba inotonhora, semapuranga edenga uye madziro emadziro.Nekuda kwehuremu hwayo huremu, kupisa kwekudzivirira, kusapinda kwemvura, kushongedzwa uye humwe hunhu, uye kufambisa kuri nyore (kuiswa), kufambira mberi kwekuvaka nekukurumidza, inofarirwa kwazvo pakati pevagadziri, kuvaka uye vanogadzira.
High-density (density 300 ~ 700kg/m3) PU rigid furo kana girazi faibha yakasimbiswa rigid furo ipurasitiki yefuro, inozivikanwawo se.polywood.Inogona kutsiva huni seakasiyana epamusoro-giredhi profiles, mabhodhi, zvinhu zvemitambo, zvekushongedza zvinhu,kumbafenicha,magirazi mafuremu,trowel,headboard yemubhedha ,prosthesis,upholstery,zvishongedzo zvemwenje, uyekutevedzera matanda ekuveza mhizha, nezvimwewo, uye chitarisiko uye ruvara rwezvigadzirwa zvinogona kugadziriswa maererano nezvinodiwa, izvo zvine tarisiro yemusika wakafara.Iyo yakaomeswa foam yakagadzirwa nekuwedzera murazvo wemoto une yakanyanya kukwirisa murazvo kupfuura huni.
Kuumba koronauye mitsara yepurasita ese ari maviri emukati ekushongedza mitsara, asi zvigadzirwa zvekugadzira uye kuvaka zvakasiyana.Mitsetse yePU inogadzirwa nePU synthetic raw materials.Iyo inogadzirwa ne-high-pressure foam yepolymer foam, uye inogadzirwa neyakaomarara pu foam.Iri rigid pu foam inosanganiswa nezvikamu zviviri pakumhanya kwakanyanya mumushini wekuperfusion, yobva yapinda muforoma kuumba nekuumba.Epidermis yakaoma.Isiri-chepfu uye isingakuvadzi, ine hushamwari hwakatipoteredza.
Crown moldingshaana kuremara, akatsemuka, kana kuora;corrosion resistance, asidhi uye alkali kuramba, uye inogona kuchengetedza kugadzikana kwezvinhu gore rose.Hakuna zvipfukuto, kana mujuru;hapana kunyura kwemvura, hapana seepage, inogona kugezwa zvakananga.High thermal insulation, chinhu chakanakisa chekupisa chinopisa chigadzirwa, hachiburitse kutonhora uye kupisa mabhiriji.
Zvipfekomannequinsinzvimbo itsva yekushandisa muindasitiri yepolyurethane.Modelsndechimwe chezvinhu zvakakosha muchitoro chembatya.Vanogona kupfekedza chitoro uye kuratidza zvakanakisa zvembatya.Mhando dzembatya dziripo pamusika dzakagadzirwa nefiberglass fiber, mapurasitiki nezvimwe zvinhu.Fiberglass faibha haina kusakara kupfeka, haina brittle, uye haina elasticity.Plastics ane hurema hwakadai sesimba risina simba uye hupenyu hupfupi.Iyo polyurethane hembe modhi ine zvakanakira kupfeka kwakanaka kuramba, simba rakanaka, elasticity, yakanaka cushioning kuita, uye yakakwirira dhigirii yekufananidza.
7.Zvimwe zvakajairika application
Pamusoro pezvishandiso zviri pamusoro, polyurethane rigid foam inogona zvakare kushandiswa kuzadza gonhi uye kugadzirwa kwehove dzinoyangarara mabhora, nezvimwe.
Polyurethane foam yakazadzwa gonhi rinotaridzika zvakafanana nechero rimwe gonhi, zvisinei, chimiro chemukati chakasiyana zvachose.Kazhinji gonhi risina pendi rine buri mukati, kana kuzadzwa nebepa reuchi, nepo polyurethane rigid furo-izere gonhi harina chete rakasvibirira uye rinoenderana nemamiriro ekunze, asiwo rinosimbisa kusimba kwegonhi remusuwo, zvichiita kuti gonhi rive rakasimba uye rakasimba. , ingave inorema chinhu kudzvanywa, mabubble emvura, Kunyangwe yakapiswa mumoto, inogona kuve nechokwadi kuti haizomboremara.Iyi tekinoroji inobvisa magonhi akaumbwa, Magonhi emapuranga anowanzo kunetsa senge deformation uye unyoro.
