mea paakiki
ʻano kemika
ʻO ka mea paʻakikī e pili ana i kahi mea hiki ke hoʻonui i ka maʻalahi o ke kiʻi paʻa.Kekahi thermosetting resin adhesives, e like me ka epoxy resin, phenolic resin a me unsaturated polyester resin adhesives ma hope o ka ho'ōla, haʻahaʻa elongation, nui fragility, i ka wa o ka paʻa kahua ma lalo o waho ikaika mea maʻalahi e māwae, a me ka hoonui wikiwiki, i ka hopena i ka nahae, luhi kū'ē, hiki. ʻaʻole hoʻohana ʻia e like me ka hoʻopaʻa ʻana.No laila, pono e hōʻemi i ka brittleness, hoʻonui i ka paʻakikī a hoʻomaikaʻi i ka ikaika o ka halihali.ʻO ka mea hiki ke hōʻemi i ka brittleness a hoʻonui i ka paʻakikī me ka ʻole o ka hoʻopili ʻana i nā waiwai nui ʻē aʻe o ka adhesive ʻo ia ka mea paʻakikī.Hiki ke hoʻokaʻawale ʻia i loko o ka lāʻau lapaʻau toughening a me ka thermoplastic elastomer toughening agent
Hoʻopuka huahana a me nā hiʻohiʻona
(1) ʻO kēia ʻano o nā ʻano ʻano mea hoʻopaʻa paʻakikī, ʻo ia ka nui o ka wai polysulfide rubber, ka wai acrylic wai, ka wai polybutadiene rubber, ka nitrile rubber, ka ethylene propylene rubber a me ka styrene butadiene rubber, etc.
(2) thermoplastic elastomer ʻO Thermoplastic elastomer kahi ʻano mea synthetic e hōʻike ana i ka elasticity rubber ma ka lumi wela a hiki ke palaki ʻia i ka wela kiʻekiʻe.No laila, loaʻa i kēia ʻano polymer nā hiʻohiʻona o ka lāʻau a me ka thermoplastic, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoikaika paʻakikī o nā mea hoʻohuihui, a hiki ke hoʻohana ʻia e like me ka matrix material of composite material.ʻO kēia ʻano mea nui ka polyurethane, styrene, polyolefin, polyester, interregular 1, 2-polybutadiene a me nā polyamides a me nā huahana ʻē aʻe, i kēia manawa ma ke ʻano he mea paʻakikī o nā mea hoʻohui i hoʻohana hou aku i ka styrene a me ka polyolefin.
(3) ʻO nā mea hoʻopaʻapaʻa ʻē aʻe ʻO nā mea hana paʻakikī ʻē aʻe i kūpono no nā composites he polyamides haʻahaʻa haʻahaʻa haʻahaʻa a me nā mea hoʻoikaika paʻakikī haʻahaʻa haʻahaʻa, e like me nā esters phthalate.Hiki ke kapa ʻia kahi mea hoʻoikaika ikaika ʻole he plasticizer, ʻaʻole i komo i ka hoʻōla ʻana o ka resin.
hoʻohana
ʻO ka mea hoʻopaʻa paʻakikī he kūpono ia no nā adhesives, rubber, coatings a me nā huahana ʻē aʻe.He ʻano mea kōkua kōkua ia e hiki ke hōʻemi i ka brittleness o nā mea composite a hoʻomaikaʻi i ka hopena o ka hopena o nā mea hoʻohui.Hiki ke hoʻokaʻawale ʻia i ka mea hoʻoikaika ikaika a me ka mea hoʻoikaika ikaika ʻole.ʻO ka mea hoʻoikaika ikaika e pili ana i kāna kaulahao molekala i loaʻa nā pūʻulu ikaika e hiki ke hana me ka resin matrix, hiki ke hana i kahi hoʻolālā pūnaewele, hoʻohui i kahi ʻāpana o ke kaulahao maʻalahi, a pēlā e hoʻomaikaʻi ai i ka hopena o ka mea hoʻohui.ʻO ka mea hoʻoikaika ikaika ʻole he ʻano mea hoʻoikaika paʻakikī i hiki ke hoʻoheheʻe ʻia me ka resin matrix akā ʻaʻole komo i ka hopena kemika.
pūʻolo a me ka lawe ʻana
B. Hiki ke hoʻohana ʻia kēia huahana, 25KG, BAERRLS.
C. E kūʻai i sila ma kahi anuanu, maloʻo a me ka makani ma loko.Pono e hoʻopaʻa paʻa ʻia nā pahu ma hope o kēlā me kēia hoʻohana ma mua o ka hoʻohana ʻana.
D. Pono e hoʻopaʻa maikaʻi ʻia kēia huahana i ka wā o ka lawe ʻana e pale aku i ka makū, ka alkali ikaika a me ka waikawa, ka ua a me nā mea haumia ʻē aʻe mai ka hui ʻana.
