Cellulose fiber mukuvaka

Akakosha ekuvaka fibers ndeaya: cellulose ether, methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC), hydroxyethyl cellulose (HEC), carboxymethyl cellulose (CMC), lignin fiber, Cellulose fiber.

Nekuda kwehunhu hwe cellulose pachayo, senge yakasikwa hydrophilicity, yakanakisa kubata simba, hombe faibha yakananga nzvimbo, uye kusimba kwakanyanya uye simba, nezvimwe, mushure mekuwedzera kune kongiri, pasi pekuita kwekunyura kwemvura uye simba rekunze, inoumba. Huwandu hukuru hwemafibhi akaenzana akagovaniswa zvakanaka hunogona kudzivirira zvinobudirira kuitika kwekutsemuka kunokonzerwa nepurasitiki shrinkage, yakaoma shrinkage uye tembiricha shanduko yekongiri, uye zvakanyanya kunatsiridza michina yekongiri.

Cellulose faibha dzinoita kuti simende ive hydrate zvakanyanya, inoderedza zvakanyanya mavhodhi mukongiri, uye inogadzira kongiri denser, nekudaro inovandudza kudzivirira kwechando, kupindira kwemvura, uye chloride ion permeability yekongiri, uye kupa kongiri nekusimba kuri nani.

(1) Anti-kutsemuka mhedzisiro pakongiri

Cellulose fibers akagoverwa matatu-dimensionally mukongiri, iyo inogona kunyatso kudzikisa kushushikana kwekusungirirwa pamucheto we micro-cracks, kushaya simba kana kubvisa kushushikana kunokonzerwa nekuderera kwekongiri kana dhaka, uye kudzivirira kuitika uye kuwedzera kwe micro-cracks.

(2) Kuvandudza kusamira kwekongiri

Iyo yunifomu yekugovera cellulose fiber mukongiri inoumba sisitimu inotsigira, iyo inotadzisa kupatsanurwa kwemvura pamusoro uye kugadzika kweaggregates, inoderedza kubuda kwekongiri, inoderedza kubuda kweropa kwekongiri, uye inoderedza zvakanyanya porosity mukongiri, saka Kusapinda kwekongiri. kongiri inovandudzwa zvakanyanya.

(3) Kuvandudza kutonhora-kunyunguduka kwekongiri

Nekuda kwekuvapo kweselulosi fiber mukongiri, inogona kunyatso kudzikisa kusungirirwa kwekushushikana kwekongiri kunokonzerwa neakawanda kutonhora-kunyungudika kutenderera, uye kudzivirira kuwedzera kuwedzera kwema micro-cracks.Mukuwedzera, nekuda kwekuvandudzwa kwekongiri impermeability, zvinobatsirawo kuvandudza yayo yechando-thaw kuramba.

(4) Kuvandudza maitiro ekupikisa uye kuoma kwekongiri

Cellulose fibers inobatsira kubata basa rekongiri zvikamu pazvinenge zvakanganiswa, uye nekuda kweiyo crack resistance effect yefibers, kana kongiri yaiswa pamitoro inorema, mafibhi anogona kudzivirira kukurumidza kuwedzera kwemukati mekuputika, saka inogona kunyatso kusimudzira. kukanganisa kupikisa kwekrete uye kuoma.

(5) Kuvandudzwa kwekongiri yakasimba

Nekuda kweiyo yakanaka crack resistance effect ye cellulose fibers, kuitika uye kukura kwekutsemuka kunodzikiswa zvakanyanya, uye kuderedzwa kwemukati porosity kunonotsa kukora uye kupinda kwemwando munzvimbo yekunze uye makemikari media, chloride munyu, nezvimwewo, nekuda. kune nhamba yakawanda yekuputika Yakaderedzwa, kuparara kwekusimbiswa kukuru kwechimiro kunoderedzwa, kuitira kuti kusimba kwekrete kunovandudzwa zvikuru uye kunowedzera.

(6) Kuvandudzwa kwekupisa kwekushisa kwekongiri

Mukongiri, kunyanya mukongiri yakasimba-yakasimba, cellulose fiber inowedzerwa, nekuti ine nhamba huru yeinofanana yakagovaniswa fiber monofilaments, iyo inopa hutatu-dimensional isingaverengeki kugovera uye inoumba matatu-dimensional network chimiro.Kana tembiricha yemukati yemurazvo-yakabikwa kongiri nhengo inokwira kusvika 165 Kana tembiricha iri pamusoro pe ℃, mafibhi anonyunguduka uye anoumba nzira dzakabatana nemukati kuti yakasimba-yakanyanya-kudzvanywa mhepo kutiza kubva mukati mekongiri, saka inogona kunyatso kudzivirira kuputika. munzvimbo yemoto uye inovandudza zvakanyanya kusimba kwekongiri.

Iyo anti-seepage uye anti-crack fiber inogona kuwedzera simba uye anti-seepage kuita kwekongiri.Iko kusanganiswa kwefiber tekinoroji uye kongiri tekinoroji inogona kugadzira simbi fiber uye synthetic fibers inogona kuvandudza mashandiro ekongiri uye kugadzirisa mhando yeinjiniya.Iyo yekutanga inokodzera madhamu, nhandare dzendege, High-speed Highway uye mamwe mapurojekiti anogona kutamba anti-cracking, anti-seepage, kukanganisa kupikisa uye flexural properties, iyo yekupedzisira inogona kudzivirira kutanga kuputika kwekongiri, uye kudzivirira pamusoro pekutanga. kugadzira zvinhu zvekongiri.Iine migumisiro yakanaka pakudzivirira kuvhara kwekuvhara, kuvandudza kuchengetedza kwemvura, kunatsiridza kugadzikana kwekugadzirwa uye kukodzera kwekuvaka, kuwedzera simba, nekusimudzira kunamatira kumusoro.

Fiber tekinoroji inoshandiswa zvakanyanya mumigwagwa yeasphalt, kongiri, dhaka, gypsum zvigadzirwa, huni pulp sponge nemimwe minda, nzvimbo dzemigwagwa uye nzvimbo dzekupaka munzvimbo dzinopisa uye dzinonaya mvura;anti-skid nzvimbo dzeexpressways, nzira dzemudhorobha, uye migwagwa inotenderera;bhiriji dhizaini pavement, kunyanya Steel bridge deck pavement;Alpine matunhu, kudzivirira tembiricha shrinkage makatsemuka;Mugwagwa unorema zvikamu zvemotokari, mutoro unorema uye zvikamu zvemotokari zvakawandisa;Mharadzano dzemigwagwa yemudhorobha, zviteshi zvemabhazi, mayadhi ekutakura zvinhu, zviteshi zvechiteshi.
