Chii Chinoshandiswa nePolyurethane Foam Sealant?
Chisimbiso chefuro chePolyurethanechinhu chinoshandiswa zvakasiyana-siyana mumabasa akasiyana-siyana, kunyanya mukuvaka nekuvandudza dzimba. Heano mamwe mashandisirwo akajairika:
Kudzivirira:Inopa kudzivirira kupisa kwakanaka, ichibatsira kuderedza mari yemagetsi nekudzivirira kurasikirwa kana kuwedzera kwekupisa muzvivako.
Kuvhara Mhepo:Furo iri rinokura kana richishandiswa, richizadza mipata nemakomba akakomberedza mahwindo, magonhi, nemamwe maburi, izvo zvinobatsira kudzivirira mhepo inodonha uye kuvandudza hunhu hwemhepo mumba.
Kudzivirira ruzha:Inogona kubatsira kuderedza kutapurirana kweruzha pakati pemakamuri kana kubva kunze, zvichiita kuti ishande mukudzivirira ruzha.
Chidziviriro chehunyoro:Furo repolyurethane rinogona kushanda sechidziviriro kubva kuhunyoro, richibatsira kudzivirira kupinda kwemvura uye kukuvara kunogona kuitika nekuda kwefungus nefungus.
Rutsigiro rweMaumbirwo:Mune zvimwe zviitiko,Chisimbiso chePU Foaminogona kupa rutsigiro rwekuwedzera rwechivakwa, kunyanya munzvimbo dzinodiwa zvinhu zvakareruka.
Kuzadza Maburi Nemitswe:Inoshanda pakuzadza nzvimbo dzakakura uye dzisina chinhu mumadziro, pasi, uye padenga, pamwe chete nepanopinda mapaipi emvura nemagetsi.
Kukwira uye Kunamatira:Inogona kushandiswa kuchengetedza zvinhu panzvimbo, zvakaita semafuremu emahwindo, mafuremu emasuo, nezvimwe zvinhu.
Kudzora Zvipembenene:Nekuvhara nzvimbo dzekupinda, zvinogona kubatsira kudzivirira zvipembenene kuti zvisapinde muchivako.
Chii Chisinganamatire Foam yePu?
Chivharo chePolyurethane (PU) chinozivikanwa nekunamira kwacho kwakasimba, asi kune zvimwe zvinhu nenzvimbo zvachisinganamati zvakanaka kana kuti zvingasanamati zvachose. Heano mimwe mienzaniso yakajairika:
Polyethylene nePolypropylene:Mapurasitiki aya ane simba shoma pamusoro, zvichiita kuti zviomere kuti furo rePU ribatane zvinobudirira.
Teflon (PTFE):Chinhu ichi chisinganamatire chakagadzirirwa kubvisa zvinonamira, kusanganisira furo rePU.
Silikoni:Kunyange zvazvo furo rePU richigona kunamira pane dzimwe nzvimbo dzesilicone, kazhinji haribatani zvakanaka ne silicone sealants dzakacheneswa.
Nzvimbo dzine mafuta kana mafuta:Chero chinhu chakasvibiswa nemafuta, mafuta, kana wakisi chinogona kudzivirira kunamira zvakanaka.
Zvimwe Zvekuputira:Mamwe mapendi, mavarnish, kana ma sealant zvinogona kugadzira chipingamupinyi chisingakwanise kunamira pa PU furo zvinobudirira.
Nzvimbo Dzakatsetseka, Dzisina Maburi:Nzvimbo dzakapfava zvikuru, dzakadai segirazi kana simbi dzakaposhwa, dzinogona kusakwanisa kubata furo zvakakwana.
Nzvimbo Dzakanyorova Kana Dzakanyorova:Furo rePU rinoda nzvimbo yakaoma kuti rinyatsonamira; kuriisa panzvimbo dzakanyorova kunogona kukonzera kusabatana zvakanaka.
Kushandiswa kwePU Foam
1. Zvakanakisa pakuisa mapaneru ekudzivirira kupisa uye nzvimbo dzisina chinhu panguva yekuisa glue.
2. Inokurudzirwa kuti zvinhu zvekuvaka zvemhando yehuni zvinamatire kongiri, simbi nezvimwewo.
3. Mapurogiramu aida kuwedzera zvishoma.
4. Kuisa uye kuparadzanisa mafuremu emahwindo nemasuo.
Zvinhu zvirimo
Imhando imwe chete, isingadhuri uye inoshanda zvakanaka nePolyurethane foam. Yakaiswa musoro wepurasitiki weadapter wekushandisa nepfuti yefoam kana uswa. Furo racho rinokura uye rinopora nekuda kwehunyoro mumhepo. Rinoshandiswa pakuvaka zvakasiyana-siyana. Rakanaka kwazvo pakuzadza nekuvhara nekushandisa simba rakanaka rekuisa, kupisa kwakanyanya uye kudzikamisa inzwi. Rinodzivirira nharaunda sezvo risina CFC.

Ndeupi Musiyano Uripo Pakati pePu Sealant neSilicone Sealant?
Musiyano uripo pakati pe polyurethane (PU) sealant ne silicone sealant wakakosha, sezvo mhando yega yega ine hunhu hwayo hwakasiyana uye mashandisirwo akakodzera. Heano misiyano mikuru:
1. Maitiro Ekugadzira uye Kurapa:
Chisimbiso chePU: Yakagadzirwa nepolyurethane, inoporesa kuburikidza nemakemikari ane hunyoro mumhepo. Inowanzo wedzera kana ikashandiswa, ichizadza mipata zvinobudirira.
Silicone Sealant: Yakagadzirwa nemasilicone polymers, inoporesa kuburikidza nemaitiro anonzi "neutral curaring," ayo asingade hunyoro. Inoramba ichichinjika mushure mekupora.
2. Kunamira:
PU Sealant: Kazhinji ine kunamatira kwakanaka kune zvakasiyana-siyana zve substrates, kusanganisira huni, simbi, nekongiri. Inogona kubatana zvakanaka nenzvimbo dzine maburi uye dzisina maburi.
Silicone Sealant: Inonamatira zvakanaka panzvimbo dzakawanda, asi kunamira kwayo kunogona kusashanda zvakanaka pane zvimwe zvinhu zvakaita sepurasitiki kana nzvimbo dzine mafuta.
3. Kuchinjika uye Kufamba:
Chisimbiso chePU: Inopa kuchinjika kwakanaka asi inogona kusapfava kupfuura silicone. Yakakodzera kushandiswa apo kufamba kunotarisirwa asi kungasakwanise kubata kufamba kwakanyanya pamwe nesilicone.
Silicone Sealant: Inochinjika zvakanyanya uye inogona kugamuchira kufamba kwakakosha pasina kutsemuka kana kurasikirwa nekunamatira, zvichiita kuti ive yakakodzera majoini anokura uye anokotama.
4. Kugara kwenguva refu uye Kuramba kweMamiriro ekunze:
PU Sealant: Kazhinji haipindi chiedza cheUV uye mamiriro ekunze, asi inogona kuora nekufamba kwenguva kana ikaiswa pachiedza chezuva chakananga isina chinodzivirira.
Silicone Sealant: Inodzivirira UV zvakanyanya uye haipindi mvura inonaya, zvichiita kuti ikwanise kushandiswa panze. Haikurumidzi kuora kana yasviba neUV.
5. Kuramba Kupisa:
PU Sealant: Inogona kutsungirira tembiricha dzakasiyana-siyana asi inogona kusashanda zvakanaka kana kuchipisa zvakanyanya kana tichienzanisa nesilicone.
Silicone Sealant: Kazhinji ine kutsungirira kwakakura kwekushisa, zvichiita kuti ive yakakodzera kushandiswa pakupisa kwakanyanya.
6. Mashandisirwo:
PU Sealant: Inoshandiswa zvakanyanya pakuvaka, kuputira, uye kuvhara mipata iri pamadziro, padenga, uye kumativi emahwindo nemasuo.
Silicone Sealant: Inoshandiswa zvikuru mudzimba dzekugezera, makicheni, nedzimwe nzvimbo uko kudzivirira mvura kwakakosha, sekuvharira masinki, matabhu, uye mashawa.
7. Kugona kupendwa:
PU Sealant: Inogona kupendwa pamusoro payo kana yangoiswa, zvichiita kuti ive yakakodzera kushandiswa uko runako rwakakosha.
Silicone Sealant: Kazhinji haipendike, sezvo pendi isinganamati zvakanaka panzvimbo dzesilicone.
