Sebopeho sa Monyako le Window Sealant

E le karolo ea bohlokoa ea thepa ea ho tiisa kaho, ts'ebetso ea mamati le lifensetere e ama ka kotloloho ho se kenelle ha moea, ho thibela metsi le ho tšoarella ha mamati le lifensetere. Moralo oa mahlale le o utloahalang o netefatsa hore sealant e na le ho khomarela hantle, elasticity, le ho hanyetsa boemo ba leholimo, ho fihlela litlhoko tsa libaka tse fapaneng.

 

Likarolo tsa mantlha tsa li-sealant tsa mamati le lifensetere li kenyelletsa se tlamella, li-filler, li-plasticizers, li-agent le li-additives. Setlamo, e leng karolo ea mantlha ea sealant, hangata se sebelisa li-polymers tse kang silicone, polyurethane, kapa acrylates, 'me se lekanyetsa litšobotsi tsa mantlha tsa sealant. Li-binders tsa silicone li fana ka khanyetso e ntle ea mocheso o phahameng le o tlase le ho hanyetsa boemo ba leholimo, ho etsa hore li tšoanelehe bakeng sa maemo a feteletseng. Li-binders tsa polyurethane li fana ka sekhomaretsi se matla le elasticity, se etsa hore li tšoanelehe bakeng sa ho tiisa ka matla. Li-binders tsa Acrylate li omella kapele 'me li loketse ho koala lemati le fensetere ka hare.

Li-fillers, tse kang calcium carbonate, carbon black, kapa silica, li sebelisoa ho ntlafatsa thepa ea 'mele ea sealant, ho matlafatsa ho thatafala, ho hanyetsa abrasion, le ho hanyetsa ho fokotseha. Li-plasticizers (tse kang phthalates) li ntlafatsa ho tenyetseha ha sealant, ho se thibela ho peperana ha mocheso o fetoha. Lisebelisoa tsa ho folisa li khothalletsa ho kopana-ho hokahana ha li-sealant, ho li fetola ho tloha ho seela ho ea boemong bo tiileng. Mekhoa e tloaelehileng ea ho phekola e kenyelletsa ho folisa mongobo (mohlala, li-silicone sealants) le ho phekola ka lik'hemik'hale (mohlala, li-polyurethane sealants).

Ho feta moo, li-additives tse kang li-antioxidants, li-absorber tsa UV, le li-thixotropic li ka ntlafatsa ho hanyetsa botsofali le ho sebetsa ha sealant. Mahlahana a Thixotropic a thibela sealant hore e se ke ea sebetsa ha e sebelisoa libakeng tse otlolohileng, ho etsa bonnete ba hore ho tlatsoa junifomo.

Ka kakaretso, ho hlophisoa ha li-sealants tsa menyako le lifensetere ho hloka hore ho nahanoe ka botlalo mofuta oa thepa ea motheo, karo-karolelano ea li-filler, le khetho ea tlatsetso ho netefatsa ho khomarela, elasticity, le ho tšoarella, ho matlafatsa katleho ea ho tiisa le bophelo ba tšebeletso ea mamati le lifensetere.
