Ni ubuhe bwoko bwa fibre ikoreshwa muri polymer mortar?

Ongeraho fibre kuri polymer mortar kugirango utezimbere imikorere yuzuye ya minisiteri yabaye uburyo busanzwe kandi bushoboka. Fibre ikoreshwa cyane niyi ikurikira

Alkali irwanya fiberglass?

Fibre y'ibirahuri ikorwa no gushonga dioxyde ya silicon, oxyde irimo aluminium, calcium, boron nibindi bintu, hamwe nibikoresho bike byo gutunganya nka sodium oxyde na potasiyumu oxyde mumipira yikirahure, hanyuma gushonga no gushushanya imipira yikirahure mubikomeye. Buri rudodo rwakuwe mubikomeye rwitwa monofilament, kandi monofilaments zose zakuwe mubikomeye ziteranirizwa mumudodo mbisi (gukurura) nyuma yo kunyura mumatanki. Nyuma yo gukwega, irashobora gukoreshwa muri polymer mortar.

Imikorere iranga fibre yibirahure nimbaraga nyinshi, modulus nkeya, kuramba cyane, coefficente yo kwaguka kumurongo muto, hamwe nubushyuhe buke bwumuriro. Imbaraga zingana za fibre fibre irenze kure imbaraga zibyuma bitandukanye (1010-1815 MPa).

Fibre fibre?

Ikintu nyamukuru kigizwe na vinylon ni inzoga za polyvinyl, ariko inzoga ya vinyl ntabwo ihagaze. Mubisanzwe, vinyl alcool acetate (vinyl acetate) ifite imikorere ihamye ikoreshwa nka monomer kugirango polymerize, hanyuma acetate ya polyvinyl ivamo iranywa inzoga kugirango ibone inzoga za polyvinyl. Iyo silike imaze kuvurwa na formaldehyde, vinylon irwanya amazi ashyushye irashobora kuboneka. Ubushyuhe bwo gushonga (225-230C) ya alcool ya polyvinyl iruta ubushyuhe bwangirika (200-220C), bityo ikazunguruka no kuzunguruka.

Vinylon ifite hygroscopique ikomeye kandi ni ubwoko bwa hygroscopique butandukanye muri fibre synthique, yegereye ipamba (8%). Vinylon irakomeye gato kurenza ipamba kandi ikomeye cyane kuruta ubwoya. Kurwanya ruswa no kurwanya urumuri: kudashonga muri acide kama rusange, alcool, esters hamwe nigitereko cyamatara ya peteroli, ntabwo byoroshye kubumba, kandi gutakaza imbaraga ntabwo ari binini iyo uhuye nizuba. Ikibi ni uko kurwanya amazi ashyushye atari byiza bihagije kandi elastique ni mibi.

Fibre Acrylic?

Yerekeza kuri fibre synthique yakozwe no kuzunguruka cyangwa kuzunguruka byumye hamwe na hejuru ya 85% ya copolymer ya acrylonitrile na monomers ya kabiri na gatatu.

Fibre ya Acrylic ifite urumuri rwiza cyane rwo guhangana nikirere, nicyo cyiza mumyenda isanzwe. Iyo fibre acrylic ihuye nizuba kumwaka umwe, imbaraga zayo zizagabanukaho 20% gusa. Fibre ya Acrylic ifite imiti ihamye, irwanya aside, irwanya alkali irwanya imbaraga, irwanya okiside hamwe nudukoko twangiza. Nyamara, fibre ya acrylic izahinduka umuhondo muri lye, na macromolecules izacika. Imiterere ya kwasi-kristalline ya fibre acrylic ituma fibre thermoelastic. Byongeye kandi, fibre acrylic ifite ubushyuhe bwiza, nta ndwara, kandi ntatinya udukoko, ariko ifite imyambarire idahwitse kandi idahwitse.

Polypropilene fibre?

Fibre polyolefin ikozwe muri stereoregular isotactic polypropylene polymer mukuzunguruka. Ubucucike bugereranije ni buto muri fibre synthique, imbaraga zumye kandi zitose zirangana, kandi imiti irwanya ruswa ni nziza. Ariko izuba risaza rirakennye. Iyo polypropilene mesh fibre ishyizwe muri minisiteri, mugihe cyo kuvanga minisiteri, ihuriro ryambukiranya hagati ya fibre monofilaments isenywa no guswera no guterana kwa minisiteri ubwayo, hanyuma fibre monofilament cyangwa imiterere y'urusobe irakingurwa rwose, bityo nkukumenya ingano Ingaruka za fibre nyinshi ya polypropilene ivanze neza na beto.

Nylon fibre?

Polyamide, izwi cyane nka nylon, ni ijambo rusange ryimyanda ya termoplastique irimo amide amide yagiye asubiramo - [NHCO] - kumurongo nyamukuru wa molekile.

Nylon ifite imbaraga za mashini nyinshi, koroshya cyane, kurwanya ubushyuhe, coefficient de fraisse nkeya, kwihanganira kwambara, kwikuramo amavuta, kwishongora no kugabanya urusaku, kurwanya amavuta, kurwanya aside irike, kurwanya alkali hamwe n’umuti rusange, kwifata neza kwamashanyarazi, bifite Self- kuzimya, kutagira uburozi, impumuro nziza, kurwanya ikirere cyiza, gusiga irangi nabi. Ikibi ni uko ifite amazi menshi, bigira ingaruka kumiterere no mumashanyarazi. Gukomeza fibre birashobora kugabanya kwinjiza amazi ya resin, kugirango ikore munsi yubushyuhe bwinshi nubushuhe bwinshi. Nylon ifitanye isano cyane na fibre yibirahure.

Polyethylene fibre?

Fibre ya polyolefin yazungurutse kumurongo wa polyethylene (polyethylene yuzuye cyane) mukuzunguruka. Ibiranga ibikoresho ni:

(1) Imbaraga za fibre no kuramba byegereye ibya polypropilene;

(2) Ubushobozi bwo kwinjiza amazi busa nubwa polypropilene, kandi igipimo cyo kugarura ubuhehere ni zeru mubihe bisanzwe byikirere;

(3) Ifite imiterere ihamye yimiti, irwanya imiti myiza kandi irwanya ruswa;

.

(5) Ifite amashanyarazi meza. Kurwanya urumuri ni bibi, kandi biroroshye gusaza munsi yumucyo wumucyo.

Aramide fibre?

Urunigi nyamukuru rwa polymer macromolecule rugizwe nimpeta zimpumuro nziza hamwe na amide, kandi byibuze 85% byamatsinda ya amide ahujwe nimpeta ya aromatic; atome ya azote hamwe nitsinda rya karubone mumatsinda ya amide ya buri gice gisubiramo bihujwe neza nimpeta ya aromatic Polymer ihuza atome ya karubone igasimbuza imwe muri atome ya hydrogène yitwa aramid resin, kandi fibre zayivuyemo zitwa hamwe. aramid fibre.

Fibre ya Aramide ifite imiterere myiza yubukanishi ningufu nkimbaraga zingana cyane, modulus ndende cyane, ubucucike buke, kwinjiza imbaraga no kwinjiza ihungabana, kwambara nabi, kurwanya ingaruka, kurwanya umunaniro, no guhagarara neza. Kwangirika kwimiti, kurwanya ubushyuhe bwinshi, kwaguka kwinshi, ubushyuhe buke bwumuriro, kudashya, kudashonga nibindi bintu byiza byumuriro nibintu byiza bya dielectric.

fibre?

Fibre yimbaho ​​bivuga urugingo rukora rugizwe nurukuta rwimyanya ngari hamwe na selile fibre hamwe nibyobo byiza bisa, kandi nikimwe mubice byingenzi bigize xylem.

Fibre yimbaho ​​ni fibre isanzwe ikurura amazi kandi ntishobora gushonga mumazi. Ifite imiterere ihindagurika kandi itandukanye.
