Kusarudzwa kwechipiri sealant kune insulating girazi

Girazi rinochengetedza simba rezvivakwa zvakaita sedzimba, iro rine yakanakisa kupisa kwekupisa uye kuita kwemazwi ekudzivirira, uye yakanaka uye inoshanda. Sealant yegirazi yekuisa insulating haiverengere chikamu chepamusoro chemutengo wegirazi inodzivirira, asi yakakosha pakugara uye yakachengeteka kushandiswa kwegirazi inodzivirira, saka ungasarudza sei?

Nezve insulating girazi

Insulating girazi inogadzirwa nezvidimbu zviviri (kana kupfuura) zvegirazi uye spacers zvakabatanidzwa pamwechete. Mhando yekuisa chisimbiso inonyanya kutora nzira yeglue strip uye nzira yekubatanidza glue. Parizvino, chisimbiso chechipiri mune glue joint sealing structure inonyanya kushandiswa. Chimiro chakaratidzwa mumufananidzo: zvidimbu zviviri zvegirazi zvakaparadzaniswa nespacers, spacer uye girazi zvakanamwa nebutyl glue kumberi, uye mukati me spacer izere ne molecular sieve, uye girazi mupendero uye kunze kwe spacer inoumbwa. Iyo gap yakavharwa nechisimbiso chechipiri.

Mhando dzechipiri sealants ye insulating girazi

Kune marudzi matatu makuru ekudzivirira girazi rechipiri sealants: silicone, polyurethane uye polysulfide. Nekudaro, nekuda kwepolysulfide, polyurethane adhesive ine kushomeka kweUV kuchembera, uye kana iyo yekubatanidza negirazi yakavhenekerwa nechiedza chezuva kwenguva yakareba, degumming ichaitika. Kana chiitiko chacho chikaitika, pepa rekunze regirazi rinodzivirira regirazi rakavanzika rejira rejira rinodonha kana kuiswa chisimbiso kwegirazi rinodzivirira regirazi rinotsigira girazi remadziro kuchakundikana. Iyo molecular chimiro chesilicone sealant inoita kuti silicone sealant ive neyakanakira yakakwira uye yakaderera tembiricha kuramba, kusamira kwemamiriro ekunze uye ultraviolet kuchembera kuramba, uye panguva imwe chete, mwero wekunyudzwa kwemvura wakadzikira, saka silicone inonyanya kushandiswa pamusika. .

Njodzi dzeKutadza Kushandisa

Matambudziko anokonzerwa nekusarudzwa kusina kukodzera kwechipiri chisimbiso chinogona kugoverwa muzvikamu zviviri zvinotevera: imwe ndiyo kurasikirwa kwekushandiswa kwebasa regirazi rekudzivirira, kureva kuti, basa rekutanga regirazi rekudzivirira rakarasika; imwe yacho inobatana nekuchengetedzwa kwekushandiswa kwegirazi rekudzivirira- - Ndiko kuti, njodzi yekuchengeteka inokonzerwa nekudonha kwegirazi rekunze girazi.

Zvikonzero zvekutadza kwekuvhara magirazi zvisimbiso zvinowanzo:

Mukucherechedzwa kwenjodzi dzepamadziro emadziro, zvinowanikwa kuburikidza nekuongorora kuti pane zvikonzero zvitatu zvikuru zvekudonha kwegirazi rekunze:

1.Kuenderana kwegirazi rekudzivirira girazi rechipiri sealant;

2.Kuitira kuchengetedza mari, mapato akakodzera anoteedzera mitengo yakaderera, uye yechipiri chisimbiso chekudzivirira girazi chinoshandisa zvisiri-silicone structural sealants senge polysulfide uye silicone kuvaka sealants;

3.Vamwe vashandi vekuvaka havana hunyanzvi uye havana kuomarara, zvichikonzera dambudziko rehupamhi hwejekiseni regirazi rekudzivirira girazi yechipiri sealant.

Kuchengetedza kwekusarudzwa kwechipiri sealant

Iyo yechipiri sealant ye insulating girazi ine pesvedzero huru pamhando uye sevhisi yehupenyu hwe insulating girazi. Iyo structural sealant ye insulating girazi inotoenderana zvakananga nekuchengetedzwa kwemadziro eketeni. Nokudaro, hatifaniri kungosarudza chigadzirwa chakanaka, asiwo sarudza chigadzirwa chakanaka.

Kutanga, inoenderana-yepamusoro uye pane-inoda. Chechipiri, usashandise zvisimbiso zvakazadzwa nemafuta. Pakupedzisira, sarudza mhando ine mukurumbira yakaita sejunbond
