Sealant o se mea faʻamaufaʻailoga e faʻaleagaina i foliga o le faʻamaufaʻailoga, e le faigofie ona tafe, ma e iai se mea faʻapipiʻi. O se mea fa'apipi'i fa'aaoga e fa'atumu ai avanoa i le va o mea faitino e fai ai se vaega fa'amaufa'ailoga. O loʻo i ai galuega o le anti-leakage, le susu, anti-vibration, leo faʻafefe ma le vevela.
E masani lava ona faʻavae i luga o mea faʻagogo poʻo mea e le faʻamagoina e pei ole asphalt, resini faʻanatura poʻo resini gaosia, paʻu natura poʻo paʻu gaosia. E faia i mea faʻapipiʻi e pei o le talc, omea, carbon black, titanium dioxide ma asbestos, ona faʻaopoopoina lea o plasticizers, solvents, curing agents, accelerators, etc.
Fa'avasegaina o fa'amaufa'ailoga
E mafai ona vaevaeina sealant i sealant elastic, gasket sealant vai ma vaega e tolu o le putty faʻamau.
E tusa ai ma le fa'avasegaga o vaila'au:e mafai ona vaevaeina i ituaiga paʻu, resin ituaiga, suauu-faavae ituaiga ma sealant polymer natura. O lenei faʻavasegaga auala e mafai ona maua ai uiga o mea polymer, faʻaalia lo latou teteʻe o le vevela, faʻamaufaʻailogaina ma fetuutuunaʻi i faʻasalalauga eseese.
ituaiga pa'u:O lenei ituaiga faʻamaufaʻailoga e faʻavae i luga o le paʻu. Pa'u e masani ona fa'aaogaina o pa'u polysulfide, pa'u silikoni, pa'u polyurethane, pa'u neoprene ma pa'u butyl.
Ituaiga resini:O lenei ituaiga fa'amaufa'ailoga e fa'avae ile resini. O resini e masani ona faʻaaogaina o resini epoxy, resini polyester unsaturated, resini phenolic, resini polyacrylic, resini polyvinyl chloride, ma isi.
Fa'avae suau'u:O lenei ituaiga fa'amaufa'ailoga e fa'avae suau'u. O suau'u masani e fa'aaogaina o suau'u fuala'au eseese e pei ole suauu linseed, suauu castor ma le suauu tung, ma suauu manu e pei ole suauu i'a.
Fa'avasegaga e tusa ai ma le talosaga:e mafai ona vaevaeina i ituaiga vevela maualuga, ituaiga tetee malulu, ituaiga mamafa ma isi.
Fa'avasegaga e fa'atatau i mea e fai ata tifaga:E mafai ona vaevaeina i ituaiga adhesion mago, ituaiga peelable mago, ituaiga pipii e le mago ma semi-mamago ituaiga viscoelastic.
Fa'avasegaga ile fa'aoga:E mafai ona vaevaeina i le faʻamaufaʻailoga faufale, faʻamaufaʻailoga taʻavale, faʻamaufaʻailoga faʻapipiʻi, faʻamaufaʻailoga faʻapipiʻi, faʻamaufaʻailoga mining ma isi ituaiga.
E tusa ai ma le faatinoga ina ua uma ona fausia:e mafai ona vaevaeina i ni ituaiga se lua: fa'amalolo fa'amaufa'ailoga ma fa'amaufa'ailoga semi-curing. Faatasi ai ma i latou, e mafai ona vaevaeina le faʻamaufaʻailoga faʻamaʻi i le maʻaʻa ma fetuutuunai. O le faʻamaufaʻailoga malosi e faʻamautu pe a maeʻa le vulcanization poʻo le faʻamalosia, ma e seasea maua le elasticity, e le mafai ona punou, ma e masani lava e le mafai ona faʻafefe; fa'amaufa'ailoga fetu'utu'una'i e fa'amalulu ma vaivai pe a mae'a fa'ama'i. O le fa'amaufa'ailoga e le fa'amagoina o se fa'amaufa'ailoga malu malu o lo'o fa'atumauina pea se tackifier e le fa'amago pe a uma ona fau ma fa'aauau pea ona alu i luga o le tulaga.
