Njengoko ubushushu buqhubeka bunyuka, umswakama emoyeni uyanda, nto leyo eya kuba nefuthe ekuqineni kweemveliso ze-silicone sealant. Ngenxa yokuba ukuqiniswa kwe-sealant kufuneka kuxhomekeke kumswakama osemoyeni, utshintsho lobushushu kunye nomswakama kwindawo esingqongileyo luya kuba nefuthe elikhulu ekusetyenzisweni kweemveliso ze-silicone sealant. Ngamanye amaxesha, kuya kubakho amaqamza amakhulu namancinci kwi-glue joint. Emva kokusika, ingaphakathi liba ngenanto. Amaqamza kwi-sealant aya kunciphisa i-viscosity yesakhiwo se-sealant kwaye anciphise kakhulu isiphumo sokutywina.
Ulandelelwano lolwakhiwo lwesitywini solwakhiwo (isitywini solwakhiwo lodonga lwekhethini, isitywini sesibini solwakhiwo sendawo engenanto, njl.njl.):
1. Ukucoca i-substrate
Ehlotyeni, ubushushu buphezulu kwaye isinyibilikisi sokucoca siyatshintshatshintsha, ngoko ke kufuneka kuqwalaselwe impembelelo kwisiphumo sokucoca.
2. Faka ulwelo lweprimer
Ehlotyeni, ubushushu kunye nokufuma kuphezulu, kwaye i-primer ilula ukuyinyibilikisa kwaye ilahlekelwe ngumsebenzi wayo emoyeni. Kufuneka kuqatshelwe ukufaka iglu ngokukhawuleza emva kokusebenzisa i-primer. Kwangaxeshanye, kufuneka kuqatshelwe ukuba xa uthatha i-primer, inani lamaxesha kunye nexesha i-primer evezwa ngalo emoyeni kufuneka lincitshiswe kangangoko, kwaye kungcono ukusebenzisa iibhotile ezincinci zokukhupha.
3. Inaliti
Emva kokuba iglu ifakiwe, isitywini esimelana nemozulu asinakusetyenziswa ngaphandle ngoko nangoko, kungenjalo isantya sokunyanga sesitywini solwakhiwo siya kuncipha kakhulu.
4. Ukucheba
Ukusika kufuneka kwenziwe kwangoko emva kokuba kugqityiwe ukufakwa kweglue. Ukusika kwenza kube lula ukudibana phakathi kwe-sealant kunye necala le-interface. 5. Iirekhodi kunye nokuchonga Emva kokuba iinkqubo ezingentla zigqityiwe, bhala phantsi kwaye ufake ilebhile ngexesha. 6. Ukugcinwa Into enye kufuneka icocwe ixesha elaneleyo phantsi kweemeko ezingashukumiyo nezingenaxinzelelo ukuqinisekisa ukuba i-structural sealant incamathela ngokwaneleyo.
