Fa'amaufa'ailoga e fa'atatau i se mea fa'amaufa'ailoga e fa'aleagaina i foliga o le fa'amaufa'ailoga, e le faigofie ona tafe, ma e iai se fa'apipi'i fa'apitoa.
O se mea faʻapipiʻi faʻaaogaina e faʻatumu ai avanoa mo le faʻamaufaʻailogaina. O loʻo i ai galuega o le anti-leakage, le susu, anti-vibration, leo faʻafefe ma le vevela. E masani lava, o mea faʻagogo faʻamago pe leai foi e pei o le asphalt, resini masani poʻo le resin synthetic, paʻu masani poʻo le paʻu synthetic e faʻaaogaina e fai ma mea faʻavae, ma faʻapipiʻi mea faʻapipiʻi e pei ole talc, omea, carbon black, titanium dioxide ma asbestos e faʻaopoopoina. Plasticizers, solvents, curing agents, accelerators, etc. E mafai ona vaevaeina i ni vaega se tolu: sealant elastic, gasket faʻamaufaʻailoga vai ma putty faʻamau. E faʻaaogaina lautele i le faʻamaufaʻailogaina o le fausiaina, felauaiga, mea faʻaeletoroni ma vaega.
E tele ituaiga o faʻamaufaʻailoga: Faʻamau faʻamaufaʻailoga silikoni, faʻamaufaʻailoga polyurethane, faʻamaufaʻailoga polysulfide, faʻamau faʻamaufaʻailoga, faʻamaufaʻailoga anaerobic, faʻamaufaʻailoga epoxy, faʻamaufaʻailoga butyl, faʻamaufaʻailoga neoprene, faʻamau PVC, ma faʻamau faʻamau.
O mea taua o sealant
(1) Faʻaaliga: O le faʻaalia o le faʻamaufaʻailoga e masani lava ona fuafuaina e ala i le faʻasalalauina o le faʻatumu i totonu o le faʻavae. O le fa'atumu o se pauta malo. A maeʻa ona faʻataʻapeʻapeina e se kulimi, se olo ma se masini paneta, e mafai ona faʻasalalau tutusa i totonu o le paʻu faavae e fai ai se paʻu lelei. O sina vaega itiiti o sala tupe po'o oneone e talia ma masani. Afai e le fa'asalalauina lelei le fa'atumu, o le a aliali mai le tele o mea'ai mata'utia. I le faʻaopoopoga i le faʻasalalauina o mea faʻatumu, o isi mea faʻapitoa o le a aʻafia ai foʻi foliga o le oloa, e pei o le faʻafefiloi o mea eleelea, crusting, ma isi.
(2) Malosi
(3) Malosi tensile
(4) Faaumiumi
(5) Tensile modulus ma le mafai ona suia
(6) Fa'apipi'i i le mea'ai
(7) Extrusion: O le faatinoga lea o le fausia o sealant O se mea e faʻaaogaina e faʻaalia ai le faigata o le faʻamaufaʻailoga pe a faʻaaogaina. O le kelu mafiafia tele o le a le mafai ona fa'auluina, ma o le a matua faigata lava ona fa'apipi'i pe a fa'aaogaina. Ae peitaʻi, afai o le kelu e fai manifinifi tele naʻo le mafaufau i le extrudability, o le a aʻafia ai le thixotropy o le faʻamau. O le extrudability e mafai ona fuaina i le metotia faʻamaonia i le tulaga faʻale-atunuu.
(8) Thixotropy: O le isi lea mea o le faʻatinoga o le fausiaina o le faʻamau. Thixotropy o le faʻafeagai o le suavai, o lona uiga e naʻo le faʻamaufaʻailoga e mafai ona suia lona foliga i lalo o se mamafa, ma mafai ona faatumauina lona foliga pe a leai se malosi mai fafo. foliga e aunoa ma le tafe. O le faʻamautuina o le sag faʻamaonia e le tulaga faʻale-malo o le faʻamasinoga o le thixotropy o le faʻamaufaʻailoga.
