ʻO Styrene-butadiene (SB) latex kahi ʻano maʻamau o ka polymer emulsion i hoʻohana ʻia i nā ʻano hana ʻoihana a me nā ʻoihana.No ka mea, ua haku ʻia ʻelua ʻano monomer, styrene a me butadiene, ua helu ʻia ka SB latex ma ke ʻano he copolymer.Loaʻa ʻia ka Styrene mai ka hana ʻana i ka benzene a me ka ethylene, a ʻo ka butadiene kahi hua o ka ethylene.
He ʻokoʻa ka latex Styrene-butadiene mai kāna mau monomer ʻelua a me ka latex maoli, i hana ʻia mai ke kohu o nā lāʻau Hevea brasiliensis.He ʻokoʻa hoʻi ia mai kahi pūhui hana ʻē aʻe, ʻo ka styrene-butadiene rubber (SBR), ka mea i kaʻana like i ka inoa akā hāʻawi i kahi pūʻulu o nā waiwai.
Ka Hana ʻana o Styrene-Butadiene Latex
Hana ʻia ka latex Styrene-butadiene ma o ke kaʻina hana emulsion polymer.Hoʻopili kēia i ka hoʻohui ʻana i nā monomers i ka wai me nā surfactants, initiators, carboxylic acids a me nā monomers kūikawā.Hoʻomaka ka poʻe hoʻomaka i ka polymerization chain-rection e hoʻohui i ka monomer styrene i ka monomer butadiene.ʻO Butadiene ponoʻī ka hui ʻana o nā hui vinyl ʻelua, no laila hiki iā ia ke hana me nā ʻāpana monomer ʻehā.ʻO ka hopena, hiki iā ia ke hoʻolōʻihi i ka ulu ʻana o ke kaulahao polymer akā hiki ke hoʻopili i kekahi kaulahao polymer i kekahi.Kapa ʻia kēia ʻo crosslinking, a he mea nui ia i ke kemika styrene-butadiene.ʻAʻole e hoʻoheheʻe ʻia ka ʻāpana crosslinked o ka polymer i loko o nā mea hoʻoheheʻe kūpono akā ua pehu a hana i kahi matrix like-gel.ʻO ka hapa nui o nā polymers styrene-butadiene pāʻoihana e hoʻopili nui ʻia, no laila, loaʻa iā lākou kahi ʻano gel kiʻekiʻe, kahi waiwai koʻikoʻi i mana ikaika i ka hana o ka latex, e ʻae ai i ka paʻakikī, ka ikaika, a me ka elasticity ma mua o nā mea ʻē aʻe.Ma luna aʻe, e ʻimi mākou pehea e hoʻohana maikaʻi ʻia ai kēia mau waiwai ma waena o nā ʻoihana a me nā noi.
Hoohana Kalepa
Hāʻawi ʻo Styrene-butadiene latex i nā pono he nui, me ka ʻae ʻana o ka filler a me ke koena tensile/elongation.ʻO ka maʻalahi o kēia copolymer e hiki ai i kahi helu kokoke ʻole o ka hui ʻana e hopena i ke kūpaʻa wai kiʻekiʻe a me ka hoʻopili ʻana i nā substrates paʻakikī.ʻO kēia mau hiʻohiʻona o ka SB latex e hoʻolilo i kēia synthetic i mea nui i kahi pūʻulu o nā mākeke.Hoʻohana mau ʻia nā SB latex formulations e like me ka uhi ʻana i nā huahana pepa, e like me nā makasina, nā lele a me nā catalogs, e loaʻa ai ka nani kiʻekiʻe, ka paʻi maikaʻi, a me ke kūʻē ʻana i ka aila a me ka wai.Hoʻonui ka SB latex i ka mana hoʻopaʻa o ka puaʻa a, ʻo ia hoʻi, e hoʻomaʻamaʻa i ka pepa, ʻoi aku ka paʻakikī, ʻoi aku ka mālamalama a me ka pale wai.Ma ke ʻano he bonus i hoʻohui ʻia, ʻoi aku ka liʻiliʻi o ka SB latex ma mua o nā uhi ʻokoʻa.He koho kaulana ʻo SB latex no nā mea hoʻopili i kekahi mau ʻoihana e like me ka papahele.No ka laʻana, ʻike ʻia ka polymer ma ke ʻano he uhi hope o nā textiles e like me nā kāpeti i hoʻopaʻa ʻia.Hāʻawi ka uhi hope i ka pale wai a hoʻopaʻa i nā ʻōpala i kahi, kahi e hoʻomaikaʻi ai i ke kūpaʻa a hoʻemi i ka haki ʻana ma ka lihi.ʻO kēia kekahi mau mea hoʻohana o ka styrene-butadiene latex.ʻO ka ʻoiaʻiʻo, hāʻawi ia i nā mea hiki ʻole, e like me ka mea i hōʻike ʻia e kona pono no nā ala holo, nā uhi lole lole, nā mea hoʻopili paʻakikī, a me nā lole i ulana ʻole ʻia.ʻO Styrene butadiene polymer emulsions kekahi mea koʻikoʻi i loko o nā membrane i hoʻohana ʻia i ka wai, a me nā pale pale MVTR haʻahaʻa no ka ʻeke ʻai.
