Haeba silicone sealant e na le mathata a boleng, e tla lebisa ho lutla ha metsi, ho lutla ha moea le mathata a mang, a tla ama ka ho teba ho tiea ha moea le ho thibela metsi a mamati le lifensetere.
Mapetso le ho lutla ha metsi ho bakoang ke ho hloleha ha lemati le lifensetere sealant
Joale re khetha sealant se nepahetseng joang bakeng sa mamati le lifensetere?
1. Khetha ka nepo lihlahisoa tse lumellanang le maemo
Nakong ea khetho ea sealant, tlhokomelo ha ea lokela ho lefshoa eseng feela ho maemo ao e kopanang le 'ona, empa hape le boemo ba eona ba ho falla.Bokhoni ba ho falla ke index ea bohlokoa ka ho fetisisa ea ho lekanya elasticity ea sealant.Ha matla a ho falla a phahame, a ntlafatsa boleng ba silicone sealant.Ts'ebetso le ho kenya mamati le lifensetere li lokela ho khetha lihlahisoa tse nang le matla a ho falla a seng ka tlase ho 12.5 ho netefatsa ho tiea ha moea ka nako e telele le ho tiea ha metsi mamati le lifensetere.
Nakong ea ho kenya le ho sebelisa mamati le lifensetere, phello ea ho kopanya pakeng tsa sealant e tloaelehileng le konkreite ea samente hangata e mpe ho feta e nang le litlaleho tsa aluminium kapa likhalase tsa mamati le lifensetere.Ka hona, ho loketse haholo ho khetha lihlahisoa tse lumellanang le JC/T 881 e le tiiso ea ho kenya mamati le lifensetere.
Lihlahisoa tse nang le boemo bo phahameng ba ho falla li na le matla a matla a ho mamella liphetoho tsa ho falla ha manonyeletso.Ho kgothaletswa ho khetha lihlahisoa tse nang le boemo bo phahameng ba ho falla ka hohle kamoo ho ka khonehang.
2. Khethasiliconelihlahisoa tsa sealant ka nepo ho ea ka morero
Lifensetere tse patiloeng tsa foreimi le lifensetere tse patiloeng tse bulang li hloka sealant ea sebopeho ho bapala karolo ea maqhama a sebopeho.Silicone structural sealant e tlameha ho sebelisoa, 'me bophara ba eona ba tlamahano le botenya bo lokela ho finyella litlhoko tsa moralo.
Nakong ea ho kenngoa ha mamati le lifensetere, sekontiri bakeng sa manonyeletso a majoe kapa manonyeletso a nang le majoe ka lehlakoreng le leng e tla ba sekontiri se khethehileng sa majoe se finyellang maemo a GB/T 23261.
Sekontiri se thibelang mollo se loketse haholoanyane mamati le lifensetere tse sa cheng kapa mamati a ka ntle le lifensetere tsa meaho tse hlokang botšepehi ba mollo.
Libakeng tsa kopo tse nang le litlhoko tse khethehileng tsa thibelo ea hlobo, joalo ka kichineng, libate tsa bohloeki le likarolo tse lefifi le tse metsi, ho koaloa ha mamati le lifensetere ho lokela ho sebelisa sealant ea bopaki ba hlobo.
3. U se ke ua khetha silicone sealant e tletseng oli!
Hona joale, 'maraka o tletse palo e kholo ea oli e tletseng mamati le li-sealants tsa lifensetere, tse tletseng oli e ngata ea liminerale 'me li na le bothata bo bobe ba botsofali, bo tla lebisa mathateng a mangata a boleng.
Silicone sealant e kopantsoeng le oli ea liminerale e bitsoa "oli e tletseng silicone sealant" indastering.Oli ea liminerale ke ea saturated alkane petroleum distillation.Hobane sebopeho sa eona sa limolek'hule se fapane haholo le sa silicone, ho lumellana ha eona le silicone sealant system ha se hantle, 'me e tla falla ebe e kenella ka ntle ho silicone sealant ka mor'a nako.Ka hona, "sealant e tletseng oli" e na le elasticity e ntle qalong, empa ka mor'a ho sebelisoa ka nako e itseng, oli e tletseng liminerale e falla 'me e phunyeletse ho tloha ho sealant,' me sealant se tla honyela, se thatafale, se phunye, se be se be le bothata ba e seng tlamahano.
Boholo ba li-silicone sealant tse theko e tlase 'marakeng li tletse oli ea liminerale,' me litaba tsa silicone polymer ea mantlha li tlase haholo ho 50%, 'me tse ling li ka tlase ho 20%.
Haeba tiiso ea fensetere e tlatsang khase e kopana le khalase e sireletsang, oli e tlatsitsoeng ea liminerale e tla falla ebe e kenella ka har'a khalase e sireletsang, e leng se tla fella ka ho qhibiliha ha rabara ea butyl e tiisang ea khalase e sireletsang le phallo ea oli.
Khetha lihlahisoa tsa boleng bo holimo tsa sealant.Le hoja theko ea sealant e rekiloeng sethaleng sa pele e phahame hanyenyane, ts'ebetso ea eona e ka bolokoa nako e telele ntle le mathata a boleng.Khetha "sealant e tletseng oli e theko e tlaase", le hoja theko e le theko e tlaase, litšenyehelo tsa pele tsa lichelete li fokotsehile hanyenyane;Leha ho le joalo, ka mor'a hore mathata a hlahe, litšenyehelo tsa tlhokomelo ea morao-rao, litšenyehelo tsa sehlahisoa, litšenyehelo tsa basebetsi, tahlehelo ea brand, joalo-joalo nakong ea ho tsosolosa e ka 'na ea e-ba makhetlo a' maloa kapa esita le makhetlo a mangata theko ea sealant ka boeona;E ne e sa boloke chelete feela, empa e ekelitse mathata a mangata ho basebelisi.
