Ko Structural Adhesives Inodzivirira Mvura? Nhungamiro Yakakwana uye Inoshanda
Iko kusapinda kwemvura kuita kwezvimiro zvinonamira zvinoenderana nemhando chaiyo uye mamiriro ekushandisa; kusarudzwa kwakanangwa kunodiwa kuti ibudirire kuvharika chisimbiso.
Basa guru rezvinonamira zvemuumbirwo rakakwira-kusimba kwekubatana, ukuwo kuita kwawo kusapinda mvura kuchisiyana zvichienderana nemagadzirirwo. Silicone structural adhesives (yakadai semhando 995) ndiyo yekutanga kusarudzwa kwekunze kwekudzivirira mvura, kupa zuva uye kupikisa kwechando, zvakakodzera padenga uye kunze kwemadziro emadziro; polyurethane structural adhesives (yakadai seE60HP) yakanyatsogadzirirwa nzvimbo dzine hunyoro, inopa elasticity uye mildew resistance, yakakodzera dzimba dzekugezera nekicheni; maindasitiri-magiredhi ekunamidzira (akadai seLoctite AA 352) anogona kubata midziyo yepasi pemvura, asi inoda kusanganiswa kwakasimba. Ziva kuti zvinonamirwa zvakajairika zvinongopa dziviriro yenguva pfupi-yekupfapfaidza uye inotadza kukundikana mushure mekunyudzwa kwenguva refu mumvura.
Mamiriro ezvinhu-kusarudzwa kwakavakirwa kunofanirwa kutevedzera misimboti mitatu: Zvinonamira zveSilicone zvinofarirwa kune nharaunda dzekunze, zvinoramba zvakatsiga patembiricha kubva -40 madhigirii kusvika 150 madhigirii; polyurethane adhesives inokurudzirwa kunzvimbo dzine hunyoro, sezvavanowedzera uye vanobvumirana nematairi; zvigadzirwa zvemaindasitiri zvinofanirwa kushandiswa munzvimbo dzakakosha (senge mota nematangi emvura). Mienzaniso yepasi rose inoratidza kuti mushandisi akashandisa Qiandinghe 9900 mhando silicone sealant kwemakore matatu pasina chero mvura inoyerera, asi substrate yakakuvadzwa panguva yekubviswa nekuda kwekunyanya kunamatira.
Mafungiro matatu akajairika aripo pakuvaka: Kutanga, haasi ese anonamira emuumbirwo asingapindi mvura; semuenzaniso, mhando 998 inoda kushandiswa kwechisimbiso.
Chechipiri, kucheneswa kusina kukwana kwe substrate (yakadai semafuta akasara) kunogona kutungamirira kune chisungo chenhema, zvichiita kuti purojekiti idonhe uye inoda rework mushure memwedzi mitatu. Chechitatu, zvidimbu zvekunamira zvakanyanyisa zvinogara zvichitsemuka; imwe imba yekugezera yaida gadziriso yakakwana yekudzivirira mvura mushure memwedzi mitanhatu nekuda kwekunyanya kukora kwenamira.
Chigadziro chepamusoro ndechekushandisa kusanganiswa kwekudzivirira mvura: mushure mekuzadza majoini neadhesive yemaitiro, shandisa polyurethane coating, kana kutanga isa butyl tepi uye wozoisa iyo inonamira, uchigadzira kaviri kudzivirira. Mhando yemhinduro iyi inowanikwa munzvimbo dzepamusoro-zvinodikanwa sedzimba dzepasi nemadziva ekutuhwina.
Structural adhesive waterproofing inofanira kutevedza-nhanho nhatu dze"kusarudza, kuvaka, nekusanganisa." Kufananidza kushanda kwechigadzirwa nemamiriro ezvinhu, kunyatsotevedzera maitiro ekushanda, uye kuwedzera nezvimwe zvinhu zvinodzivirira mvura zvakakosha kuti uwane chisimbiso chinogara-chinogara uye kudzivirira kuwedzera kwakanyanya kwemari yekugadzirisa gare gare.
