Silicone aniani resin a me ke kiʻekiʻe wela ke kūpaʻa silicone mika adhesive.
Ke kūkulu nei ʻo Huo Changshun lāua ʻo Chen Rufeng mai Chenguang Chemical Research Institute, Ministry of Chemical Industry, etc.I ka hopena o 1970s, cts-103 silicone resin, i ʻike nui ʻia ʻo "silicone glass resin", ua hoʻomohala maikaʻi ʻia e ka hydropolycondensation o ka methyltriethoxysilane i mua o ka catalyst acid.Ua hoʻohana ʻia ka resin i ka mālama ʻana i ka pepa kiʻekiʻe, ka pale uhi ʻana i ka ʻili metala, a me ka hoʻopaʻa ʻana i ka pepa mica a i ʻole ka pauka mika i ka wā mua.I ka makahiki 1980, ua hoʻohana ʻo Sanhua, Xue Zhiqing a me Li Yansheng, nā mea hana resin ma Shanghai, i ka resin hoʻololi cation paʻa e like me ka catalyst acid no ka manawa pōkole.Ua hoʻohui ʻia nā resins silikoni māmā a ʻaʻahu o sar-1 a me sar-2 ma ka hoʻohui ʻana i kahi liʻiliʻi o dimethyldiethoxysilane i loko o ka monomethyltriethoxysilane nui.ʻAʻohe koena inorganic acid i loko o ka resin, no laila paʻa loa ka hana mālama ʻana o ka huahana, ʻaʻohe ʻike cementation i hoʻokahi makahiki ma hope.Ma muli o ka hoʻokomo ʻana i kahi mea liʻiliʻi o nā lako maka difunctional, paʻakikī nā huahana sar-2, waena a palupalu, me kahi ākea ākea o nā noi.Hiki ke hoʻohana nui ʻia i ke aniani, ka plastik, ka metala a me nā mea ʻē aʻe, ʻoi aku ka maikaʻi no ka pale ʻana i nā plastic transparent e like me polycarbonate, polystyrene a me PVC, a no ka uhi ʻana i ka moisture-proof a me ka insulation o nā mea uila, e hoʻokumu koke i ka nui- hana unahi.
Mai 1980 a i 1982, Qi hongqiu, Li Yan a me Cui Zuoming mai Chenguang Chemical Research Institute, a mai 1981 a 1983, Xu Zhihong a me Xue Zhiqing mai Shanghai resin hale hana i hoʻohana i ka methyltrichlorosilane ma ke ʻano he kumu kumu nui e hoʻomākaukau ai i ka silicone kiʻekiʻe wela kū i ka mica adhesive.ʻO nā māka huahana ʻo mr-30 a me sar-8.Ma waho aʻe o ke kūpaʻa wela kiʻekiʻe, ka insulation uila, moisture-proof, water-proof a me nā waiwai ʻē aʻe o nā huahana organosilicon maʻamau, loaʻa i nā huahana nā waiwai adhesion kiʻekiʻe a me nā mea pale ahi.Hoʻohana nui ʻia ia no ka hana ʻana i ka pauda kiʻekiʻe o ka pauka kapuaʻi makuahine papa, ʻeleʻele paipu insulation, kiʻekiʻe wela kū'ē i ka pauda kapuaʻi makuahine papa no ke kākoʻo, mika papa no ka huli ʻana i loko o ka mīkini kuʻihao uila, etc. Hiki ke hoʻohui ʻia nā puaʻa wela wela. e like me ka uahi ʻole a me ka anti-corrosion coatings, a hiki ke hoʻohana ʻia e like me incombustible molding composite a i ʻole ceramic molding resin i haku ʻia me ke aniani fiber composite laminate a me ka silica.He waiwai nui ʻo Kina i nā kumuwaiwai mica pauda, hiki ke hoʻomohala ʻia i ke ʻano o nā huahana mica board insulating kiʻekiʻe.
He loea ʻo Jiangxi Huahao i ka hana ʻana i ka dimethyldiethoxysilane
Hoʻohana ʻo Sar-8 a me sar-9 o ka hale hana resin o Shanghai i kā lākou ala ponoʻī: hydrolyze a me alcoholysis organosilicon monomers a me ka concentrate a me ka polycondensate i ka manawa like.Ua hoʻokomo ʻia ʻo Sar-8 a me sar-9 i ka hana ʻana i ka makahiki 1983, a ua hōʻea ka huahana i kahi kokoke i hoʻokahi kaukani tona.ʻO ka methyltrichlorosilane ka waiwai nui o ka huahana, no laila inā i hana ʻia ka mr-30 a i ʻole sar-8 a i ʻole sar-9, hiki ke hoʻomaikaʻi maikaʻi ʻia ka waiwai hoʻohana o ka methyltrichlorosilane.
Organosilicon molding plastics
I ka makahiki 1960, ua makemake koke ka ʻoihana mokulele o Kina i kahi ʻano ʻano palaki silicone mold arc i hiki ke kū i ka ikaika o kēia manawa a me ka uila kiʻekiʻe no ka hana ʻana i nā hoʻololi micro.Ua hoʻomohala maikaʻi ʻo Beijing Research Institute o ka ʻoihana kemika i ka resin silicone i hoʻoheheʻe ʻia mai ka methyltrichlorosilane a hana ʻia i loko o ka palaka palaka me ka asbestos filler, ka mea i hoʻoponopono i ka pono wikiwiki o ka ʻoihana mokulele.Ua hoʻoili ʻia nā mea i ka hale hana resin Shanghai no ka hana ʻana.Eia nō naʻe, pono nā mea hoʻohana i kēia ʻano mea, no laila pono lākou e noi i ke kōkua mai Chenguang Chemical Research Institute, i neʻe i ka moku ʻo Sichuan.I mea e hoʻokō ai i nā pono koʻikoʻi o nā mea hoʻohana, Wu Shengquan et al.Ua hoʻohana ka Institute i ka hydrolysis condensation ala mai ka methyltriethoxysilane i mea hoʻomaka e hoʻomākaukau i ka resin silicone no ka hoʻoheheʻe ʻana i nā plastics me ka hana ʻoluʻolu, i mea e hoʻoponopono ai i nā pono koʻikoʻi o nā mea hoʻohana.
Mea hoʻopaʻa resin silicone
I ka hopena o nā makahiki 1960, me ka hoʻomohala ʻana o ka ʻoihana uila o Kina, pono ia e hoʻohana i nā mea hoʻopaʻa silikoni me ka insulation uila maikaʻi loa, ke kūpaʻa wela kiʻekiʻe, ka moisture-proof a me ka hoʻopau ʻole ʻana e hoʻopili i nā diodes mana nui a liʻiliʻi, triodes, resistors, capacitors, nā kaapuni hoʻohui a me nā mea uila ʻē aʻe.Ma Kina, Zhang Xinghua, he Jigang, et al.No ka Institute of chemistry o ka Chinese Academy of Sciences, a me Zhang Jikai, Li Yansheng, et al.ʻO ka hale hana resin o Shanghai i hana mua i ka hoʻomohala ʻana i ia mau resins.Ua hoʻomohala lākou i nā ʻano huahana like ʻole e hoʻopiha i ka ʻāpana kūloko.
ʻO ka uhi ʻana i hoʻololi ʻia ka resin silicone
ʻO ka silicone maʻamau ka hapa nui o polymethylsiloxane a me polyphenylsiloxane.ʻOi aku ka maikaʻi o ka hoʻohālikelike o ka resin silicone i loaʻa ka phenyl a me ka resin organic ma mua o ka resin methyl silicone.Hiki ke hoʻomaikaʻi ʻia ke kūpaʻa wela a me ka pale wai o nā uhi ākea ma ka hoʻokomo ʻana i ka phenyl silicone i loko o lākou.I ka ʻoihana uhi, hiki ke hoʻomākaukau ʻia ka siloxane kiʻekiʻe i loko o ka uhi ʻana ma o ka hui ʻana a i ʻole copolymerization o ka phenyl i loko o ka resin silicone.I ka hoʻomaka ʻana o nā makahiki 1960, ua hoʻomohala maikaʻi ka hale hana pena ʻo Tianjin a me ka hale hana resin Shanghai i ka uhi ʻana o ka resin synthetic i hoʻololi ʻia.Ua hoʻomohala ʻia nā ʻano waiwai maikaʻi, e like me ka silicone epoxy resin i hoʻololi ʻia me ke kūpaʻa wela maikaʻi a me ka pili.
