ZONKE IZIKHATHI ZOMKHIQIZO

Izinyathelo zokuqapha ama-silicone sealants.

Ama-Silicone sealants avame ukusetshenziswa ekuthuthukisweni kwekhaya ahlukaniswe abe izinhlobo ezimbili ngokuya ngezakhiwo zawo: ama-silicone sealants angathathi hlangothi nama-acid silicone sealants. Ngenxa yokuthi abantu abaningi abakuqondi ukusebenza kwama-silicone sealant, kulula ukusebenzisa ama-silicone sealant angathathi hlangothi nama-acidiic silicone sealants ngokuhlehla.
    
    Ama-silicone sealant angathathi hlangothi anokuqina okuqinile, futhi ngokuvamile asetshenziswa ngemuva kwezibuko zasendlini yokugezela lapho kungadingeki khona ukunamathela okuqinile. I-acid silicone sealant ngokuvamile isetshenziswa emlonyeni oyisimungulu ngemuva komugqa wokhuni, futhi amandla okunamathela anamandla kakhulu.

1. Inkinga evame kakhulu ye-silicone sealant imnyama kanye nesikhutha. Ngisho nokusetshenziswa kwe-silicone sealant engenamanzi kanye ne-anti-mold silicone sealant ayikwazi ukugwema ngokuphelele ukuvela kwezinkinga ezinjalo. Ngakho-ke, akufanelekile ukwakhiwa ezindaweni lapho kunamanzi noma izikhukhula isikhathi eside.

2. Labo abazi okuthile nge-silicone sealant kufanele bazi ukuthi i-silicone sealant iyinto ephilayo, encibilika kalula ezintweni ze-organic solvent ezifana namafutha, i-xylene, i-acetone, njll. Ngakho-ke, i-silicone sealant ayikwazi ukusetshenziswa nezinto ezinjalo. ukwakhiwa ku-substrate.

3. Ama-silicone sealants ajwayelekile kufanele elashwe ngokubamba iqhaza komswakama emoyeni, ngaphandle kweglue yenjongo ekhethekile nekhethekile (njengama-anaerobic adhesives), ngakho-ke uma indawo ofuna ukuyakha iyindawo evalekile futhi yome ngokwedlulele, khona-ke i-silicone evamile. i-sealant ngeke ikwazi ukwenza umsebenzi.

4. Ubuso be-silicone sealant okufanele buhlanganiswe ne-substrate kumele buhlanzeke, futhi akufanele kube khona okunye okunamathiselwe (njengothuli, njll.), ngaphandle kwalokho i-silicone sealant ngeke iboshwe ngokuqinile noma iwe ngemva kokuphulukiswa.

5. I-acid silicone sealant izokhipha igesi ecasulayo phakathi nenqubo yokwelapha, enomthelela wokucasula amehlo kanye nomgudu wokuphefumula. Ngakho-ke, kuyadingeka ukuvula iminyango namafasitela ngemva kokwakhiwa, ulinde kuze kube yilapho usuphuluke ngokuphelele, futhi ulinde ukuthi igesi lihlakaze ngaphambi kokungena.
