He huahana ikaika a maʻalahi hoʻi ka silicone sealant a i ʻole ka mea hoʻopili i hiki ke hoʻohana ʻia i nā ʻano hana like ʻole. ʻOiai ʻaʻole ikaika ka silicone sealant e like me kekahi mau sealant a i ʻole nā mea hoʻopili, noho maʻalahi loa ka silicone sealant, ʻoiai ua maloʻo loa a i ʻoleua ho'ōla ʻiaHiki i ka sila silicone ke kū i nā mahana kiʻekiʻe loa, e kūpono ia no nā noi e ʻeha nei i ka wela nui, e like me nā gaskets mīkini.
Hōʻike ka sealant silicone i hoʻōla ʻia i ke kūpaʻa maikaʻi loa i ka wā, ke kūpaʻa ʻana i ka ʻelemakule, ke kūpaʻa UV, ke kūpaʻa ozone, ke kūpaʻa wela kiʻekiʻe a me ka haʻahaʻa, ke kūpaʻa haʻalulu, ke kūpaʻa makū, a me nā waiwai pale wai; no laila, ua ākea loa kāna mau noi. I nā makahiki 1990, ua hoʻohana pinepine ʻia no ka hoʻopaʻa ʻana a me ka sila ʻana i ka ʻoihana aniani, no laila ua ʻike nui ʻia ʻo ia ʻo "glass adhesive."
Kiʻi luna: Hoʻopaʻa silicone i hoʻōla ʻia
Kiʻi hema: Hoʻopili pahu o ka sila silicone
ʻO ka mea hoʻopaʻa silicone ka mea maʻamau i hoʻokumu ʻia ma luna o 107 (hydroxy-terminated polydimethylsiloxane), a ua haku ʻia me nā mea e like me nā polymers kaumaha-molecular kiʻekiʻe, nā plasticizers, nā mea hoʻopihapiha, nā mea hoʻopili cross-linking, nā mea hoʻopili, nā mea hoʻouluulu, a me nā mea ʻē aʻe. ʻO nā plasticizers i hoʻohana pinepine ʻia e komo pū me ka ʻaila silicone, ka ʻaila keʻokeʻo, a me nā mea ʻē aʻe. ʻO nā mea hoʻopihapiha i hoʻohana pinepine ʻia e komo pū me ka calcium carbonate nano-activated, calcium carbonate kaumaha, calcium carbonate ultrafine, silica fumed, a me nā mea ʻē aʻe.
Loaʻa nā silicone sealant 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 (multi) ʻāpana ʻo ia hoʻi ka māhele ʻana o ka silicone sealant i ʻelua mau pūʻulu (a ʻoi aku paha ma mua o ʻelua) ʻāpana A a me B, ʻaʻole hiki i kekahi ʻāpana hoʻokahi ke hana i ka hoʻōla ʻana, akā ma hope o ka hui ʻana o nā ʻāpana ʻelua (a ʻoi aku paha ma mua o ʻelua), e hana lākou i ka hopena hoʻōla cross-linking e hana i nā elastomers.
Pono e hana koke ʻia ka hui ʻana ma mua o ka hoʻohana ʻana, kahi e paʻakikī ai ka hoʻohana ʻana i kēia ʻano silicone sealant.
Hiki ke hele mai ka silicone sealant ma ke ʻano he huahana hoʻokahi, me ka ʻole o ke kāwili ʻana. ʻO kekahi ʻano o ka silicone sealant huahana hoʻokahi i kapa ʻia ʻo iaKa Vulcanizing Mahana o ka Lumi(RTV). Hoʻomaka kēia ʻano sila e hoʻōla koke i ka wā e hōʻike ʻia ai i ka lewa - a i ʻole, ʻoi aku ka pololei, ka makū i ka lewa. No laila, he mea pono e hana wikiwiki ʻoe i ka wā e hoʻohana ai i ka sila silicone RTV.
Hiki ke hoʻokaʻawale ʻia ka sealant silicone hoʻokahi ʻāpana i: ke ʻano deacidification, ke ʻano dealcoholization, ke ʻano deketoxime, ke ʻano deacetone, ke ʻano deamidation, ke ʻano dehydroxylamine, a pēlā aku e like me nā mea hoʻohui like ʻole (a i ʻole nā mole liʻiliʻi i hana ʻia i ka wā o ka hoʻōla ʻana) i hoʻohana ʻia. I waena o lākou, ʻo ke ʻano deacidification, ke ʻano dealcoholization a me ke ʻano deketoxime ka mea i hoʻohana nui ʻia ma ka mākeke.
ʻO ke ʻano deacidification he methyl triacetoxysilane (a i ʻole ethyl triacetoxysilane, propyl triacetoxysilane, a pēlā aku) ma ke ʻano he mea hoʻopili, e hana ana i ka waikawa acetic i ka wā e hoʻōla ai, i ʻike nui ʻia ʻo "acid glue". ʻO kona mau pono: ikaika maikaʻi a me ka moakāka, wikiwiki ka hoʻōla ʻana. ʻO nā hemahema: hoʻonāukiuki i ka ʻala waikawa acetic, ka pala o nā metala.
ʻO ke ʻano o ka Dealcoholization he methyl trimethoxysilane (a i ʻole vinyl trimethoxysilane, a pēlā aku) ma ke ʻano he mea hoʻopili, ʻo kāna hana hoʻōla e hana i ka methanol, i ʻike nui ʻia ʻo "alcohol-type glue". ʻO kona mau pono: palekana i ke kaiapuni, ʻaʻole corrosive. Nā hemahema: lohi ka wikiwiki o ka hoʻōla ʻana, ʻilihune iki ka ola mālama.
ʻO ke ʻano o Deketo oxime he methyl tributyl ketone oxime silane (a i ʻole vinyl tributyl ketone oxime silane, a pēlā aku) ma ke ʻano he mea hoʻopili, e hana ana i ka butanone oxime i ka wā e hoʻōla ana, i ʻike nui ʻia ʻo "oxime type glue". ʻO kona mau pono: ʻaʻohe ʻala nui, hoʻopili maikaʻi i nā mea like ʻole. Nā hemahema: ka pala o ke keleawe.
Wahi a ka hoʻohana ʻana, ua māhele ʻia nā huahana i: sealant kūkulu, sealant kūpaʻa i ke aniau, sealant puka a me ka puka makani, sealant hui, sealant pale ahi, sealant anti-mildew, sealant wela kiʻekiʻe.
Wahi a ke kala o ka huahana i nā kiko: ʻeleʻele maʻamau, keʻokeʻo porcelain, moakaka, hina kālā 4 ʻano, hiki iā mākou ke hoʻokō i nā kala ʻē aʻe e like me nā koi o ka mea kūʻai aku.
Aia kekahi mau ʻano ʻē aʻe o ka silicone sealant i ʻoi aku ka ʻenehana. Hoʻokahi ʻano, i kapa ʻiaʻike i ke kaomiʻO ka sila silicone, he ʻano pipili mau loa a pili pono me ke kaomi i manaʻo ʻia - ʻo ia hoʻi, ʻoiai e "pipili mau ana," ʻaʻole ia e pipili inā palaki wale kekahi mea a kau paha i luna. ʻO kekahi ʻano ʻē aʻe i kapa ʻiaUV or ho'ōla ʻia ka radiationsealant silicone, a hoʻohana i ka mālamalama ultraviolet e hoʻōla i ka sealant. ʻO ka hope loa,hoʻonohonoho welaPono ka silicone sealant i ka wela i mea e ho'ōla ai.
Hiki ke hoʻohana ʻia ka sila silicone i nā ʻano hana like ʻole. Hoʻohana pinepine ʻia kēia ʻano sila i nā kaʻa a me nā hana pili, e like me ke kōkua no ke sila ʻana i kahi ʻenekini, me a me ka ʻole o nā gaskets. Ma muli o kona ʻoi aku ka maʻalahi, he koho maikaʻi nō hoʻi ka sila no nā hana leʻaleʻa a i ʻole nā hana lima.
