ʻO ka Sealant e pili ana i kahi mea hoʻopaʻa i hoʻoheheʻe ʻia me ke ʻano o ka ili hoʻopaʻa, ʻaʻole maʻalahi ke kahe ʻana, a loaʻa kahi adhesiveness.
He mea hoʻopili ia i hoʻohana ʻia e hoʻopiha i nā āpau hoʻonohonoho no ka sila. Loaʻa iā ia nā hana o ka anti-leakage, waterproof, anti-vibration, insulation sound and heat insulation. ʻO ka maʻamau, hoʻohana ʻia nā mea viscous maloʻo a maloʻo ʻole e like me ka asphalt, ka resin maoli a i ʻole ka resin synthetic, ka ʻōpala maoli a i ʻole ka synthetic rubber e hoʻohana ʻia ma ke ʻano he kumu kumu, a hoʻohui ʻia nā mea hoʻopihapiha inert e like me talc, pālolo, kalapona ʻeleʻele, titanium dioxide a me asbestos. Plasticizers, solvents, curing agents, accelerators, etc. Hiki ke māhele ʻia i ʻekolu mau ʻano: elastic sealant, liquid sealing gasket a sealing putty. Hoʻohana nui ʻia ia i ka sila ʻana o ke kūkulu ʻana, ka lawe ʻana, nā mea uila a me nā ʻāpana.
Nui nā ʻano mea hoʻopaʻa: Silicone sealants, polyurethane sealants, polysulfide sealants, sealants acrylic, sealants anaerobic, sealants epoxy, butyl sealants, neoprene sealants, PVC sealants, a me asphalt sealants.
ʻO nā mea nui o ka sealant
(1) Nānā: Hoʻoholo nui ʻia ke ʻano o ka sealant e ka hoʻopuehu ʻana o ka mea hoʻopiha i ke kumu. ʻO ka mea hoʻopihapiha he pauda paʻa. Ma hope o ka hoʻopuehu ʻia ʻana e ka mea kneader, ka mea wili a me ka mīkini planetary, hiki ke hoʻopuehu ʻia i loko o ka pahu kumu e hana ai i kahi paʻi maikaʻi. ʻO kahi liʻiliʻi o nā uku liʻiliʻi a i ʻole ke one ʻae ʻia a maʻamau. Inā ʻaʻole i hoʻopuehu maikaʻi ʻia ka mea hoʻopihapiha, e ʻike ʻia nā ʻāpana koʻikoʻi he nui. Ma waho aʻe o ka hoʻopuehu ʻana o nā mea hoʻopihapiha, e hoʻopili pū kekahi mau mea ʻē aʻe i ke ʻano o ka huahana, e like me ka hui ʻana o nā mea ʻalaʻala, crusting, a me nā mea ʻē aʻe.
(2) Oolea
(3) Ka ikaika tensile
(4) Elongation
(5) Tensile modulus a me ka hiki ke hoʻoneʻe
(6) Hoʻopili i ka substrate
(7) Extrusion: ʻO kēia ka hana o ka hana sealant He mea i hoʻohana ʻia e hōʻike i ka paʻakikī o ka sealant ke hoʻohana ʻia. ʻOi aku ka mānoanoa o ke kāpili e loaʻa i ka extrudability maikaʻi ʻole, a he mea paʻakikī loa ke kāpili ʻana ke hoʻohana ʻia. Eia nō naʻe, inā ʻoi aku ka lahilahi o ke kāpili me ka noʻonoʻo ʻana i ka extrudability, e hoʻopilikia ia i ka thixotropy o ka sealant. Hiki ke ana ʻia ka extrudability e ke ʻano i hōʻike ʻia ma ka standard national.
(8) Thixotropy: ʻO kēia kahi mea ʻē aʻe o ka hana hana o ka sealant. ʻO Thixotropy ka mea kū'ē i ka fluidity,ʻo ia hoʻi, hiki i ka sealant ke hoʻololi wale i konaʻano ma lalo o kekahi kaomi, a hiki ke mālama i konaʻano keʻole ka ikaika o waho. kino kahe ole. ʻO ka hoʻoholo ʻana o ka sag i ʻōlelo ʻia e ka pae aupuni ʻo ia ka hoʻoholo o ka thixotropy o ka sealant.
