ʻO ka Silicone sealant a i ʻole adhesive kahi huahana ikaika a hiki ke hoʻohana ʻia i nā noi like ʻole. ʻOiai ʻaʻole ikaika ka silikoni sealant e like me kekahi mau sealants a i ʻole adhesives, hiki ke maʻalahi loa ka sealant silicone, ʻoiai ua maloʻo loa a i ʻole.hoolaia. Hiki i ka silikoni sealant ke kū i nā wela kiʻekiʻe loa, e kūpono ana ia no nā noi e loaʻa ana i ka wela kiʻekiʻe, e like me nā gaskets engine.
Hōʻike ka silikoni sealant i hoʻōla maikaʻi ʻia i ka wā, ka pale ʻana i ka wā kahiko, ka pale ʻana o UV, ke kūpaʻa ozone, ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, ke kū ʻana o ka vibration, ka pale ʻana i ka wai, a me nā waiwai wai; no laila, nui loa kona mau hoohana. I nā makahiki 1990, hoʻohana mau ʻia no ka hoʻopaʻa ʻana a me ka sila ʻana i ka ʻoihana aniani, no laila ua kapa ʻia ʻo ia ʻo "glass adhesive."
ʻO ke kiʻi kiʻekiʻe: Hoʻōla silicone sealant
Kiʻi hema: Hoʻopili pahu pahu o ke sila silikoni
Hoʻokumu pinepine ʻia ka silicone sealant ma 107(hydroxy-terminated polydimethylsiloxane), a ua haku ʻia me nā mea e like me nā polymers high-molecular-weight, plasticizers, fillers, cross-linking agents, coupling agents, catalysts, etc. silica fumed, a me nā mea ʻē aʻe.
Hele mai nā mea hoʻopaʻa Silicone i nā ʻano like ʻole.
Wahi a ke ʻano o ka mālama ʻana, ua māhele ʻia i: ʻelua (multi) ʻāpana a me hoʻokahi ʻāpana.
ʻElua (nui) ʻāpana ʻo ia hoʻi, ua māhele ʻia ka silikoni sealant i ʻelua pūʻulu (a ʻoi aku paha ʻelua) ʻāpana A a me B, ʻaʻole hiki i kēlā me kēia ʻāpana ke hana i ka curing, akā ma hope o ka hui ʻana o nā ʻāpana ʻelua (a ʻoi aku paha ʻelua), e hoʻohua mai lākou i ka hoʻōla ʻana i ka cross-linking reaction e hana i nā elastomers.
Pono e hana koke ʻia ka hui ʻana ma mua o ka hoʻohana ʻana, ʻo ia ka mea e paʻakikī ai ka hoʻohana ʻana i kēia ʻano sealant silicone.
Hiki ke hele mai ʻo Silicone sealant ma ke ʻano he huahana hoʻokahi, me ka pono ʻole o ka hui ʻana. Ua kapa ʻia kekahi ʻano o ka silikon sealant huahana hoʻokahiVulcanizing wela o ka lumi(RTV). Hoʻomaka kēia ʻano o ka sealant e hoʻōla i ka wā e ʻike ʻia ai i ka lewa - a i ʻole, ʻoi aku ka pololei, ka makū i ka lewa. No laila, pono ʻoe e hana wikiwiki i ka hoʻohana ʻana i ka RTV silicone sealant.
Hiki ke hoʻokaʻawale ʻia ka sealant silicone ʻāpana hoʻokahi i: ʻano deacidification, ʻano dealcoholization, ʻano deketoxime, ʻano deacetone, ʻano deamidation, ʻano dehydroxylamine, a me nā mea ʻē aʻe e like me nā ʻano crosslinking ʻokoʻa (a i ʻole nā molekole liʻiliʻi i hana ʻia i ka wā hoʻōla) i hoʻohana ʻia. I waena o lākou, ʻano deacidification, ʻano dealcoholization a me ke ʻano deketoxime i hoʻohana nui ʻia i ka mākeke.
ʻO ke ʻano deacidification ʻo ka methyl triacetoxysilane (a i ʻole ethyl triacetoxysilane, propyl triacetoxysilane, a me nā mea ʻē aʻe) ma ke ʻano he crosslinking agent, kahi e hoʻopuka ai i ka acetic acid i ka wā o ka hoʻōla ʻana, i kapa ʻia ʻo "acid glue". ʻO kāna mau mea maikaʻi: ka ikaika maikaʻi a me ke aniani, ka wikiwiki hoʻōla wikiwiki. ʻO nā mea pōʻino: hoʻonāukiuki acetic acid honi, ʻino o nā metala.
ʻO ke ʻano dealcoholization i ka methyl trimethoxysilane (a i ʻole vinyl trimethoxysilane, a me nā mea ʻē aʻe) ma ke ʻano he crosslinking agent, ʻo kāna kaʻina hoʻōla e hoʻopuka i ka methanol, i ʻike mau ʻia ʻo "ʻano glue ʻano waiʻona". ʻO kāna mau mea maikaʻi: ka palekana o ke kaiapuni, non-corrosive. Nā pōʻino: lohi ka mālama ʻana, ʻilihune iki ke ola o ka mālama ʻana.
ʻO ka Deketo oxime ʻano he methyl tributyl ketone oxime silane (a i ʻole vinyl tributyl ketone oxime silane, a me nā mea ʻē aʻe) ma ke ʻano he mea hoʻohui crosslinking, kahi e hana ai i ka butanone oxime i ka wā o ka hoʻōla ʻana, i kapa ʻia ʻo "oxime type glue". ʻO kāna mau mea maikaʻi: ʻaʻohe ʻala nui, pili maikaʻi i nā mea like ʻole. Nā pōʻino: corrosion o ke keleawe.
Wahi a ka hoʻohana ʻana i nā huahana i māhele ʻia i: structural sealant, weather resistant sealant, door and window sealant, sealant joint, fire-proof sealant, anti-mildew sealant, high temperature sealant.
E like me ka waihoʻoluʻu o ka huahana i nā kikoʻī: ʻeleʻele kala maʻamau, keʻokeʻo porcelain, aniani, kala hina 4 ʻano, nā kala ʻē aʻe hiki iā mākou ke hana e like me nā koi o ka mea kūʻai aku toning.
Aia kekahi ʻano o nā ʻano ʻano ʻenehana ʻoi aʻe o ka silicone sealant. Hoʻokahi ʻano, kapa ʻiapili puʻesilicone sealant, loaʻa ka paʻa paʻa a pili pū me ka manaʻo paʻa - ʻo ia hoʻi, ʻoiai ʻo ia ka "pili," ʻaʻole ia e pili inā palaki a hoʻomaha paha kekahi mea iā ia. Ua kapa ʻia kekahi ʻanoUV or hoʻōla ʻia ka radiationsilicone sealant, a hoʻohana i ke kukui ultraviolet e hoʻōla i ka sealant. ʻO ka hope,thermosetʻO ka mea hoʻopaʻa silicone e pono ai ka ʻike i ka wela i mea e ola ai.
Hiki ke hoʻohana ʻia ka silicone sealant i nā ʻano hana like ʻole. Hoʻohana pinepine ʻia kēia ʻano sealant i nā kaʻa a me nā noi pili, e like me ke kōkua no ka hoʻopaʻa ʻana i kahi mīkini, me ka ʻole a i ʻole nā gaskets. Ma muli o kona maʻalahi, he koho maikaʻi ka sealant no nā leʻaleʻa a i ʻole nā mea hana.
