Mumakore achangopfuura, kwave nemamiriro ekunze akanyanya uye akanyanya kutenderera pasirese, izvo zvakaedzawo indasitiri yedu yekusimbisa, kunyanya kumafekitori eChinese sesu anoendesa kunze kwenyika kunzvimbo dzese dzepasi.
Mumavhiki mashoma apfuura muChina, kunaya kwemvura kunoramba kuchinaya uye tembiricha yakanyanya hazvina kusiya nzvimbo yekuzorora. Saka sei kunyatso shandisa sealants munzvimbo yakakwirira yekupisa uye yakakwirira humidity nharaunda?
1 Kurongedza uye kuchengetedza zvisimbiso
Sezvo zvisimbiso zviri zvigadzirwa zvemakemikari, nzira yekurapa ndeyekuita uye kusimba kana wasangana nehunyoro. Kana yakanyoroveswa mumvura, iyo yekunze kurongedza kwezvisimbiso inogona chete kutamba yakaganhurirwa basa. Nokudaro, muzhizha, zvisimbiso zvinofanira kuchengetwa munzvimbo yakakwirira-yenhema, inofefetera uye inotonhorera kudzivirira zvisimbiso kuti zvirege kunyura mumvura kana kunyange kunyura mumvura inokonzerwa nemamiriro ekunze ekunze, izvo zvinokanganisa mararamiro echigadzirwa uye chikonzero. kurapa matambudziko mune chigadzirwa kurongedza.
Zvisimbiso zvakanyoroveswa mumvura zvinofanirwa kubviswa kubva munzvimbo yekunyorova nekukurumidza sezvinobvira uye kuendeswa kune yakaoma uye ine mhepo. Katoni yekurongedza yekunze inofanira kubviswa, iyo nzvimbo inofanira kupukuta yakaoma uye kuiswa mukati memba kuti ishandiswe nekukurumidza.
2 Yakarurama nzira yekushandisa sealant
Usati wanyorera, ndapota teerera kune zvinotevera:
Iyo ambient tembiricha inodiwa yeSiway brandsilicone sealantzvigadzirwa ndezve: 4℃～40℃, nzvimbo yakachena ine hunyoro hwe40%～80%.
Munzvimbo dzisiri dzepamusoro tembiricha uye humidity zvinodiwa, vashandisi havakurudzirwe kuisa sealant.
Muzhizha, tembiricha yekunze yakakwira, kunyanya kumadziro emaketeni ealuminium, uko kutonhora kwakanyanya. Kana iyo ambient tembiricha uye hunyoro zvisiri mukati meiyo yakakurudzirwa renji, zvinokurudzirwa kuita diki diki resealant application test panzvimbo, uye kuita peeling adhesion bvunzo kuratidza kuti adhesion yakanaka uye hapana chakashata chiitiko pamberi. kuishandisa panzvimbo yakakura.
Panguva yekushandisa, ndapota tevera matanho ari pasi apa:
Kuvaka kutevedzana kweiyo structural sealant (yakarongeka sealant yemadziro emaketeni, maviri-layer structural sealant yemakomba, nezvimwewo):
1) Chenesa substrate
Iyo tembiricha yakakwira muzhizha, uye iyo yekuchenesa solvent iri nyore kuvhuvhuta. Nyatsoteerera kukanganiswa kwemaitiro ekuchenesa.
2) Shandisa primer (kana zvichidikanwa)
Muzhizha, tembiricha uye hunyoro zvakakwirira, uye primer iri nyore kuita hydrolyze uye kurasikirwa nebasa rayo mumhepo. Ngwarira kujova glue nekukurumidza sezvinobvira mushure mekushandisa primer. Panguva imwecheteyo, zvinofanirwa kucherechedzwa kuti kana uchitora primer, nhamba yenguva uye nguva iyo primer inosangana nemhepo inofanira kuderedzwa zvakanyanya sezvinobvira. Zvakanakisa kushandisa bhodhoro diki rekuchinja pakurongedza.
3） Sealant jekiseni
Mushure mejekiseni reglue, chisimbiso chinodzivirira mamiriro ekunze hachigone kuiswa pakarepo kunze, kana zvisina kudaro, kukurumidza kuporesa kwechisimbiso chekugadzirisa kuchaderedzwa zvakanyanya.
4) Kucheka
Mushure mekunge jekiseni reglue rapera, kucheka kunofanira kuitwa nekukasira, izvo zvinoita kuti pave nekubatana pakati pechisimbiso nedivi reiyo interface.
5) Kurekodha uye kumaka
Mushure mekunge maitiro ari pamusoro apera, rekodha uye maka nenguva.
6） Maintenance
Iyo unit inofanirwa kuporeswa kwenguva yakakwana pasi pemamiriro ekusimudzira uye asina kusimbiswa kuti ave nechokwadi chekuti chisimbiso chechimiro chine kukwana kwakakwana.
Kuvaka kutevedzana kwemamiriro ekunze-resistant sealant uye gonhi uye hwindo sealant:
1) Sealant kugadzirira pamwe chete
Iyo foam tsvimbo inosangana nechisimbiso inofanira kuchengetedzwa. Iyo tembiricha yakakwira muzhizha, uye kana furo tsvimbo yakakuvadzwa, zviri nyore kukonzera blistering; panguva imwecheteyo, kutarisisa kunofanirwa kubhadharwa kune kuenderana kwe substrate uye chisimbiso.
2） Chenesa substrate
Gungano reglue rinofanira kucheneswa panzvimbo yekubvisa guruva, mafuta, nezvimwe.
3) Shandisa primer (kana zvichidikanwa)
Kutanga, iva nechokwadi chokuti pamusoro peglue joint substrate yakaoma zvachose. Muzhizha, tembiricha uye hunyoro zvakakwirira, uye primer iri nyore hydrolyzed mumhepo uye inorasikirwa nebasa rayo. Zvinofanira kucherechedzwa kuti glue inofanira kuiswa nokukurumidza sezvinobvira mushure mokunge primer yashandiswa. Panguva imwecheteyo, inofanira kuonekwa kuti pakutora primer, nhamba uye nguva yekubatana nemhepo inofanira kuderedzwa zvakanyanya sezvinobvira. Zvakanakisa kushandisa bhodhoro diki rekuchinja pakurongedza.
4） Sealant jekiseni
Kune mamwe mabhanan'ana muzhizha. Ziva kuti mushure mekunaya kwemvura, mubatanidzwa weglue unofanirwa kuoma zvachose usati wabaya glue.
5） Kupedza
Kupisa muzhizha kwakakwirira, uye nguva yekupedzisa ipfupi pane dzimwe nguva. Mushure mekunge jekiseni reglue rapera, kupedzisa kunofanira kuitwa pakarepo.
6） Maintenance
Muchikamu chekutanga chekugadzirisa, hapafanirwe kuve nekusimuka kukuru.
Matambudziko akajairika, Maitiro ekugadzirisa nawo:
1. Nguva pfupi yekuzorora yezvikamu zviviri zvemaitiro sealant
Kutonga: Nguva yekuzorora ipfupi pane yakaderera muganho wenguva yekuzorora inokurudzirwa nemugadziri.
Chikonzero: Kupisa kwepamusoro uye hunyoro muzhizha zvinopfupisa nguva yekuzorora.
Solution: Gadzirisa reshiyo yezvikamu A uye B mukati merudzi rwakakurudzirwa nemugadziri.
2. Kusashanda kwemaitiro sealant primer
Chikonzero: Kupisa kwakanyanya uye hunyoro muzhizha, kushandiswa zvisina kunaka kweprimer kunogona kurasikirwa nebasa rayo nyore. Kusashanda primer kunotungamira kune kusabatana kwakashata kweiyo structural sealant.
Solution: Zvakanakisisa kushandisa mabhodhoro maduku kune primer. Hazvikurudzirwe kushandisa primer isina kushandiswa mu sub-bhodhoro husiku. Panguva imwecheteyo, inofanira kuonekwa kuti pakutora primer, nhamba uye nguva yekubatana pakati pekutanga nemhepo inofanira kuderedzwa zvakanyanya sezvinobvira. Uye tarisa chimiro cheprimer mune sub-bhodhoro nenguva. Kana kutaridzika kwakashanduka nekuda kwenguva yakareba yekuchengetedza, iyo primer mu sub-bhodhoro haifanirwe kushandiswa.
3. Weathering sealant / gonhi uye hwindo sealant bubbling
Nzira yekutonga: Kune mabhururu emunharaunda pamusoro pesilicone sealant. Kana kachira kakaporeswa kakavhurwa, mukati mune mhango.
Chikonzero ①: Pamusoro petsvimbo yefuro inobaiwa panguva yekuzadza, uye mweya unoburitswa kubva mugomba mushure mekudzvanywa;
Mhinduro: Rutivi rwechimuti chefuro chasangana nechisimbiso chinoramba chakamira. Kana zvakaoma kuzadza, unogona kucheka chikamu cheshure chemuti wefuro.
Chikonzero ②: Mamwe ma substrates anoita nema sealants;
Solution: Teerera kuenderana kwemhando dzakasiyana dzezvisimbiso uye substrates, uye bvunzo dzekuenderana dzinodiwa.
Chikonzero ③: Kuputika kunokonzerwa nekuwedzera kwekupisa kwegasi mune yakavharwa glue joint;
Chikonzero chaicho chinogona kunge chiri chekuti mune yese yakavharwa glue joint, mhepo yakavharirwa mune glue joint mushure mejekiseni inowedzera muhuwandu kana tembiricha yakakwira (kazhinji pamusoro pe15 ° C), ichikonzera kubhuroka pamusoro pechisimbiso chisati chaitika. solidified.
Sarudzo: Dzivisa kuiswa chisimbiso zvakakwana sezvinobvira. Kana zvichidikanwa, siya chikamu chidiki chemaburi emhepo uye uzadze iwo mushure mekunge chisimbiso chasimba.
Chikonzero ④: Iyo interface kana yekuwedzera zvinhu zvakanyorova;
Mhinduro: Usavaka pamazuva ekunaya, mirira kusvikira mamiriro ekunze akachena uye glue raoma.
Chikonzero ⑤: Kuvaka pasi pekushisa kwakanyanya kunze;
Solution: Misa kuvaka pasi pekushisa kwepamusoro mamiriro kunze uye kumirira kusvikira tembiricha yadonha isati yavakwa.
4. Nguva pfupi yekugadzirisa yemamiriro ekunze-resistant sealant / gonhi uye hwindo sealant
Chikonzero: Kupisa uye hunyoro zvakakwirira muzhizha, uye nguva yekudhonza inopfupiswa.
Solution: Gadzirisa munguva mushure mejekiseni.
Ngwarira panguva yekuvaka uye tevera mirairo kuti uone kunaka.
Kupisa kwakanyanya uye kunaya kwakanyanya matambudziko makuru, uye kune matipi ekuvaka sealant.
Bata nezvinetso panguva yakakodzera kuti uve nechokwadi chekuchengetedzwa kweprojekti.
SIWAY inokuperekedza mukati mezhizha rinopisa uye inopa runako pamwechete!
