He aha nā ʻano fiber i hoʻohana maʻamau ʻia i ka mortar polymer?

ʻO ka hoʻohui ʻana i nā fiber i ka mortar polymer e hoʻomaikaʻi i ka hana piha o ka mortar ua lilo i ala maʻamau a hiki ke hana.ʻO nā fiber i hoʻohana mau ʻia e like me kēia

Alkali-kūpaʻa fiberglass?

Hana ʻia ka fiber aniani ma ka hoʻoheheʻe ʻana i ka silicon dioxide, nā oxides i loaʻa i ka aluminika, calcium, boron a me nā mea ʻē aʻe, a me kahi mea liʻiliʻi o nā mea hana e like me ka sodium oxide a me ka potassium oxide i loko o nā pōpō aniani, a laila hoʻoheheʻe a huki i nā pōpō aniani i loko o kahi kīʻaha.Ua kapa ʻia kēlā me kēia milo i unuhi ʻia mai loko mai o ke kīʻaha he monofilament, a ʻo nā monofilament a pau i unuhi ʻia mai loko mai o ke kīʻaha ua hui ʻia i loko o kahi wili maka (tow) ma hope o ka hele ʻana i loko o ka pahu wai.Ma hope o ka ʻoki ʻia ʻana o ke kaʻa, hiki ke hoʻohana ʻia i ka mortar polymer.

ʻO nā hiʻohiʻona hana o ka fiber aniani he ikaika kiʻekiʻe, modulus haʻahaʻa, elongation kiʻekiʻe, coefficient hoʻonui laina haʻahaʻa, a me ka conductivity thermal haʻahaʻa.ʻOi aku ka ikaika o ke aniani aniani ma mua o ka ikaika o nā mea kila like ʻole (1010-1815 MPa).

Velen fiber?

ʻO ka mea nui o ka vinylon he polyvinyl alcohol, akā ʻaʻole paʻa ka waiʻona vinyl.ʻO ka mea maʻamau, hoʻohana ʻia ka vinyl alcohol acetate (vinyl acetate) me ka hana paʻa ma ke ʻano he monomer e polymerize, a laila hoʻokaʻawale ʻia ka polyvinyl acetate e loaʻa ai ka waiʻona polyvinyl.Ma hope o ka mālama ʻia ʻana o ka siliki me ka formaldehyde, hiki ke loaʻa ka vinylon pale wai wela.ʻOi aku ka kiʻekiʻe o ka wela hoʻoheheʻe ʻana (225-230C) o ka waiʻona polyvinyl ma mua o ka wela decomposition (200-220C), no laila ua wili ʻia e ka wili ʻana.

He hygroscopicity ikaika ka Vinylon a ʻo ia ka ʻano hygroscopic ʻoi loa ma waena o nā fiber synthetic, kahi kokoke i ka pulupulu (8%).ʻOi aku ka ikaika o Vinylon ma mua o ka pulupulu a ʻoi aku ka ikaika ma mua o ka hulu hipa.ʻO ke kūpaʻa ʻino a me ke kūpaʻa māmā: ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o nā ʻakika organik maʻamau, nā ʻawaʻawa, nā esters a me nā mea hoʻoheheʻe kukui ʻaila, ʻaʻole maʻalahi e hoʻoheheʻe ʻia, a ʻaʻole nui ka nalowale o ka ikaika ke ʻike ʻia i ka lā.ʻO ka hemahema, ʻaʻole maikaʻi ke kūpaʻa wai wela a ʻilihune ka elasticity.

puluniu acrylic?

E pili ana ia i ka fiber synthetic i hana ʻia e ka wili pulu a i ʻole ka wili maloʻo me ka ʻoi aku ma mua o 85% o ka copolymer o acrylonitrile a me ka lua a me ke kolu o nā monomers.

ʻO ka fiber Acrylic ka maikaʻi o ka pale māmā a me ka pale ʻana i ka wā, ʻo ia ka mea maikaʻi loa ma waena o nā fiber textile maʻamau.Ke hōʻike ʻia ka fiber acrylic i ka lā no hoʻokahi makahiki, e emi wale ana kona ikaika ma 20%.ʻO ka fiber Acrylic ka paʻa kemika maikaʻi, ka pale ʻana i ka waika, ke kūpaʻa alkali nāwaliwali, ke kūpaʻa oxidation a me ke kūpaʻa ʻana o ka solvent.Eia nō naʻe, e melemele nā ​​lau acrylic i ka lye, a e haki nā macromolecules.ʻO ka hana quasi-crystalline o ka fiber acrylic e hana i ka fiber thermoelastic.Eia kekahi, he maikaʻi ke kūpaʻa wela, ʻaʻohe maʻi, a ʻaʻole makaʻu i nā insects, akā, ʻaʻohe maikaʻi o ka ʻaʻahu a me ke kūpaʻa ʻole.

Nā pulupulu polipropylene?

He fiber polyolefin i hana ʻia mai ka stereoregular isotactic polypropylene polymer ma ka hehee ʻana.ʻO ka liʻiliʻi loa ka liʻiliʻi ma waena o nā fiber synthetic, ua like ka ikaika maloʻo a me ka pulu, a ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion.Akā ʻilihune ka lā ʻelemakule.Ke hoʻokomo ʻia ka fiber polypropylene mesh i loko o ka mortar, i ka wā o ka hui ʻana o ka mortar, ua hoʻopau ʻia ka pilina transverse ma waena o nā monofilaments fiber e ka ʻōpala a me ka friction o ka mortar ponoʻī, a ua wehe piha ʻia ka fiber monofilament a i ʻole ka ʻōnaehana pūnaewele, no laila. e ʻike i ka nui ʻO ka hopena o nā fibers polypropylene he nui i hui pū ʻia i loko o ke kaʻa.

ʻO ka fiber Aramid?

ʻO ke kaulahao nui o ka macromolecule polymer i haku ʻia me nā apo ʻala a me nā mea paʻa amide, a ma ka liʻiliʻi o 85% o nā hui amide i hoʻopaʻa pololei ʻia i nā apo ʻala;ua hoʻopaʻa pololei ʻia nā ʻātoma nitrogen a me nā pūʻulu kalapona i loko o nā hui amide o kēlā me kēia ʻāpana hana hou i nā apo ʻala ʻO ka polymer kahi i hoʻopili ʻia ai nā ʻātoma kalapona a pani i kekahi o nā ʻātoma hydrogen i kapa ʻia ʻo aramid resin, a ua kapa ʻia nā fibers i wili ʻia mai ia mea. nā lāʻau aramid.

Loaʻa i ka fiber Aramid nā waiwai mechanical a me ka ikaika e like me ka ikaika tensile kiʻekiʻe, ka modulus tensile kiʻekiʻe, ka haʻahaʻa haʻahaʻa, ka maikaʻi o ka ikehu absorption a me ka haʻalulu haʻalulu, ka pale ʻana, ka hopena hopena, ka luhi luhi, a me ke kūpaʻa dimensional.ʻO kaʻinoʻino kemika, ke kūpaʻa wela kiʻekiʻe, ka hoʻonui haʻahaʻa, ka haʻahaʻa haʻahaʻa haʻahaʻa, non-combustible, hoʻoheheʻe ʻole a me nā mea wela ʻē aʻe a me nā waiwai dielectric maikaʻi loa.

pulu laau?

ʻO ka pulupulu lāʻau e pili ana i ka ʻiʻo mechanical i haku ʻia me ka lignified thickened cell wall a me ka fiber cell me nā lua māwae maikaʻi, a ʻo ia kekahi o nā mea nui o ka xylem.

ʻO ka pulupulu lāʻau he fiber maoli ia e hoʻoheheʻe i ka wai a hiki ʻole ke hoʻoheheʻe ʻia i ka wai.Loaʻa iā ia ka maʻalahi a me ka dispersibility.
