Rubber Butyl Brominated (BIIR)

ʻO ka wehewehe pōkole:

ʻO ka brominated butyl rubber (BIIR) he isobutylene isoprene copolymer elastomer i loaʻa ka bromine ikaika.No ka mea he kaulahao nui ka brominated butyl rubber i hoʻopiha piha ʻia me ka butyl rubber, loaʻa iā ia nā ʻano hana like ʻole o ka butyl polymer, e like me ka ikaika kino kiʻekiʻe, ka hana haʻalulu haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa, kūʻokoʻa kūʻokoʻa a me ke kū ʻana o ka wā kahiko.ʻO ka mea i hana ʻia a me ka hoʻohana ʻana i ka halogenated butyl rubber inner liner ua loaʻa i nā ʻāpana radial hou i nā ʻano he nui.ʻO ka hoʻohana ʻana i ia mau polymers i loko o ka huila i loko o ka huila hiki ke hoʻomaikaʻi i ka hana paʻa paʻa, hoʻomaikaʻi i ka hoʻopili ʻana ma waena o ka liner i loko a me ke kupapaʻu a hoʻomaikaʻi i ka lōʻihi o ka paʻa.

ʻO Butyl rubber kahi polymer linear me ka isobutylene ma ke kino nui a me kahi liʻiliʻi o ka isoprene.Ma ke kaulahao nui o ka butyl rubber mole, kēlā me kēia hui methylene ʻē aʻe, aia ʻelua mau pūʻulu methyl i hoʻonohonoho ʻia i loko o ke ʻano spiral a puni ke kaulahao nui, e hana ana i kahi keakea steric nui, e hana ana i ka molecular structure o butyl rubber compact a me ke kaulahao molecular flexible. .Eia nō naʻe, hana maikaʻi ʻo ia i ka butyl rubber i ka paʻa ʻana o ka ea, ke kūlana mua ma waena o nā rubbers āpau.

Ma waho aʻe o ka paʻa o ka ea maikaʻi loa, ʻoi aku ka maikaʻi o nā vulcanizates butyl rubber.Hiki ke hoʻohana ʻia ka sulfur vulcanized butyl rubber i ka lewa no ka manawa lōʻihi ma 100 ℃ a i ʻole ka haʻahaʻa haʻahaʻa haʻahaʻa.ʻO ka mahana lawelawe o ka butyl rubber vulcanized me ka resin hiki ke hiki i 150-200 ℃.ʻO ka ʻelemakule oxygen wela o ka butyl rubber no ke ʻano degradation, a ʻo ka ʻelemakule e palupalu.Ma muli o ka haʻahaʻa haʻahaʻa o ke kaulahao mole o ka butyl rubber a me ka hopena kemika inert, ʻo ka butyl rubber ka wela maikaʻi a me ka pale ʻana o ka oxygen.

ʻO ke ʻano kālepa: brominated butyl rubber kā mākou huahana mea kūʻai.ʻO ka palena liʻiliʻi he 20 tons.

1. No ka hoʻohana ʻana i ka huila kaʻa a me ke kaʻa kaʻa mana:
ʻOi aku ka maikaʻi o ka pale ʻana i ka wela a me ka waimaka.Hiki i nā paipu i loko (me nā kaʻa kaʻa a me nā kaʻa) i hana ʻia me ka butyl rubber hiki ke hoʻomau i ka ikaika tensile maikaʻi a me ka waimaka ma hope o ka loaʻa ʻana o ka manawa lōʻihi i ke kaiapuni wela, kahi e hōʻemi ai i ka pōʻino i ka wā e hoʻohana ai.Hiki i ka butyl rubber inner tube ke hōʻoia i ka nui o ke ola a me ka palekana ma lalo o nā kūlana wela a i ʻole ma lalo o nā kūlana inflated.Hiki i ka waimaka liʻiliʻi ke hōʻemi i ka nui o ka lua a e maʻalahi a maʻalahi ka hoʻoponopono ʻana i ka pahu butyl rubber i loko.ʻO ke kūpaʻa ʻana o ka oxidation maikaʻi loa a me ka pale ʻana o ka ozone o ka butyl rubber e hana i ka butyl rubber inner tube i ke kūʻē degradation maikaʻi loa, a ʻoi aku ka maikaʻi o kona lōʻihi a me ke ola lawelawe ma mua o ka ʻōpala i loko.ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa loa o ka butyl rubber e hiki ai ke mālama ʻia ka paipu i loko o ia mea i ke kaomi inflation kūpono no ka manawa lōʻihi.ʻO kēia hana kūʻokoʻa e hiki ai i ka paipa waho ke komo like a hōʻoia i ke ola lei aliʻi maikaʻi loa.E hoʻolōʻihi i ke ola lawelawe o ke kaʻa waho, e hoʻonui i ka paʻa a me ka palekana o ka hoʻokele, e hoʻemi i ke kūpaʻa o ka ʻōwili ʻana, a laila e hoʻemi i ka hoʻohana ʻana i ka wahie e hoʻokō ai i ke kumu o ka mālama ʻana i ka ikehu.

2. No ka hoʻohana ʻana i ka pahu pahu lāʻau lapaʻau:
ʻO ka pahu pahu lāʻau lapaʻau kahi huahana lāʻau lapaʻau kūikawā no ka hoʻopaʻa ʻana a me ka hoʻopili ʻana i pili pono me nā lāʻau lapaʻau.ʻO kāna hana a me ka maikaʻi e pili pono i ka pono, palekana, kūpaʻa maikaʻi a me ka maʻalahi o nā lāʻau lapaʻau.Hoʻomaʻamaʻa pinepine ʻia nā corks lapaʻau ma lalo o ke kiʻekiʻe o ke kiʻekiʻe a me nā kūlana kiʻekiʻe a i ʻole i nā disinfectants like ʻole, a i kekahi manawa pono lākou e mālama no ka manawa lōʻihi ma lalo o nā kūlana haʻahaʻa haʻahaʻa.No laila, aia nā koi koʻikoʻi e pili ana i nā waiwai kemika, nā waiwai mechanical physical a me nā waiwai biological o ka lāʻau.Ma muli o ka pili pono ʻana o ka ʻōmole me ka lāʻau lapaʻau, hiki ke hoʻohaumia i ka lāʻau ma muli o ka hoʻopuehu ʻana o ka mea hiki ke unuhi ʻia i loko o ka pahu pahu i loko o ka lāʻau lapaʻau, a i ʻole e hōʻemi i ka hana o ka lāʻau ma muli o ke komo ʻana o kekahi mau mea i loko o ka lāʻau. e ka mea pani omole.ʻAʻole wale ka haʻahaʻa haʻahaʻa haʻahaʻa o ka butyl rubber, akā loaʻa nō hoʻi ke kūpaʻa oxidation maikaʻi loa, ka waika a me ke kūpaʻa alkali, ka pale wela a me ka pale ʻana i ka pōʻino kemika.Ma hope o ka hoʻohana ʻia ʻana o ka pahu pahu butyl rubber, hiki i ka hale hana lāʻau lapaʻau ke hoʻomaʻamaʻa i ke kaʻina hana subpacking, hoʻohana i ka pāpale alumini open, hoʻopau i ka wax sealing a hōʻemi i ke kumukūʻai, a hiki ke hoʻomaʻamaʻa i ka hoʻohana ʻana i ka injection.

3. Nā polokalamu ʻē aʻe:
Ma waho aʻe o nā mea i hoʻohana ʻia ma luna, ua loaʻa i ka butyl rubber nā mea hoʻohana penei: (1) ka uhi ʻana o nā mea hana kemika.Ma muli o kona kūpaʻa ʻino kemika maikaʻi loa, ua lilo ka butyl rubber i mea makemake no ka pale ʻana i ka corrosion o nā mea hana kemika.He haʻahaʻa loa ka pehu ʻana o ka pahu butyl i nā mea hoʻoheheʻe like ʻole, ʻo ia kekahi o nā kumu nui e hoʻohana ʻia ai ka butyl rubber ma kēia kahua.(2) Nā lole pale a me nā mea pale.ʻOiai ʻo ka nui o nā mea plastik i hoʻokaʻawale maikaʻi ʻia a me ka hana pale ʻana, hiki i nā mea elastic wale nō ke hāʻawi i ka noʻonoʻo i ka maʻalahi e pono ai no ka haʻahaʻa haʻahaʻa a me nā lole ʻoluʻolu.Ma muli o kona haʻahaʻa haʻahaʻa i nā wai a me nā kinoea, hoʻohana nui ʻia ka butyl rubber i nā lole pale, nā ponchos, nā uhi pale, nā masks gas, nā mīkina lima, nā kāmaʻa a me nā kāmaʻa.
