I-cellulose fiber ekwakhiweni

Iifiber zokwakha ezibalulekileyo zezi: i-cellulose ether, i-methyl cellulose (MC), i-hydroxypropyl methyl cellulose (HPMC), i-hydroxyethyl cellulose (HEC), i-carboxymethyl cellulose (CMC), i-lignin fiber, i-Cellulose fiber.

Ngenxa yeempawu zeselulosi ngokwayo, njenge-hydrophilicity yendalo, amandla okubamba agqwesileyo, indawo enkulu yefiber ekhethekileyo, kunye nokuqina okuphezulu kunye nokomelela, njl.njl., emva kokuba yongezwe kwikhonkrithi, phantsi kwesenzo sokumanzisa kwamanzi kunye namandla angaphandle, iyabumba. Inani elikhulu lemicu emihle esasazwa ngokulinganayo inokuthintela ngokufanelekileyo ukuvela kweentanda ezibangelwa yi-plastic shrinkage, i-shrinkage eyomileyo kunye nokutshintsha kobushushu bekhonkrithi, kwaye iphucule kakhulu iimpawu zemishini yekhonkrithi.

Iifiber zeCellulose zenza i-samente i-hydrate ngokupheleleyo, inciphisa kakhulu i-voids kwikhonkrithi, kwaye yenza i-concrete denser, ngaloo ndlela iphucula ukuxhathisa iqabaka, ukunyanzeliswa kwamanzi, kunye ne-chloride ion permeability yekhonkrithi, kwaye inika ikhonkrithi ngokuhlala okungcono.

(1) Impembelelo yokuchasana nokuqhekeka kwikhonkrithi

Imicu yeCellulose isasazwe macala amathathu kwikhonkrithi, enokunciphisa ngokufanelekileyo uxinzelelo loxinzelelo kwincam ye-micro-cracks, yenza buthathaka okanye isuse uxinzelelo olubangelwa kukuncipha kwekhonkrithi okanye udaka, kwaye ithintele ukwenzeka kunye nokwandiswa kwamaqhekeza amancinci.

(2) Ukuphucula ukungabonakali kwekhonkrithi

Ukuhanjiswa okufanayo kweefayili zeselulosi kwikhonkrithi kubumba inkqubo exhasayo, ethintela ukwahlukana kwamanzi angaphezulu kunye nokuhlaliswa kwee-aggregates, kunciphisa ukopha kwekhonkrithi, kunciphisa imijelo yokuphuma kwegazi yekhonkrithi, kwaye kunciphisa kakhulu i-porosity kwikhonkrithi, ngoko ke Ukunganyanzeki kwe-concrete. ikhonkrithi iphuculwe kakhulu.

(3) Ukuphucula ukunqanda ukunyibilika komkhenkce kwekhonkrithi

Ngenxa yobukho bemicu ye-cellulose kwikhonkrithi, inokunciphisa ngokufanelekileyo ukuxinana koxinzelelo lwe-tensile kwikhonkrithi ebangelwa yimijikelo emininzi yokunyibilikisa yomkhenkce, kwaye ithintele ukwandiswa ngakumbi kweentanda ezincinci.Ukongeza, ngenxa yokuphuculwa kokunganyanzeki kwekhonkrithi, kukwaluncedo ekuphuculeni ukumelana kwayo nokunyibilika komkhenkce.

(4) Ukuphucula ukuchasana kwempembelelo kunye nokuqina kwekhonkrithi

Imicu ye-cellulose inceda ukufunxa umsebenzi wamacandelo ekhonkrithi xa ichaphazeleka, kwaye ngenxa yempembelelo yokumelana nokuqhekeka kweentsinga, xa ikhonkrithi iphantsi kwemithwalo yempembelelo, imicu inokuthintela ukwanda ngokukhawuleza kweentanda zangaphakathi, ngoko inokuphucula ngokufanelekileyo. ukuchasana kwempembelelo yekhonkrithi kunye nokuqina.

(5) Ukuphuculwa kokuqina kwekhonkrithi

Ngenxa yefuthe elihle lokumelana nokuqhekeka kwe-cellulose fibers, ukwenzeka kunye nokuphuhliswa kweentanda kuncitshiswe kakhulu, kwaye ukunciphisa i-porosity yangaphakathi kunciphisa ukubola kunye nokungena komswakama kwimeko yangaphandle kunye nemidiya yekhemikhali, i-chloride salts, njl. ukuya kwinani elikhulu lokuqhekeka Ukunciphisa, ukubola kokuqiniswa kwesakhiwo kuyancipha, ukwenzela ukuba ukuqina kwekhonkrithi kuphuculwe kakhulu kwaye kuphuculwe.

(6) Ukuphuculwa kokumelana nokushisa okuphezulu kwekhonkrithi

Kwikhonkrithi, ngokukodwa kwikhonkrithi ephezulu, i-fiber ye-cellulose yongezwa, kuba iqulethe inani elikhulu le-fiber monofilaments esasazwa ngokufanayo, ebonisa ukusabalalisa okungahleliwe kwe-three-dimensional kwaye yenza i-network-dimensional network structure.Xa iqondo lobushushu langaphakathi lelungu lekhonkrithi elitshiswa lilangatye linyuka liye kutsho ku-165 Xa iqondo lobushushu lingaphezulu kwe-℃, iintsinga ziyanyibilika kwaye zenze imijelo edityaniswe yangaphakathi ukuze umphunga oqinileyo woxinzelelo oluphezulu ubaleke ngaphakathi kwekhonkrithi, ngoko unokuphepha ngokufanelekileyo ukugqabhuka. kwindawo yomlilo kunye nokuphucula kakhulu ukuqina kwekhonkrithi.

I-anti-seepage kunye ne-anti-crack fiber inokunyusa amandla kunye nokusebenza kwe-anti-seepage yekhonkrithi.Indibaniselwano yetekhnoloji yefiber kunye netekhnoloji yekhonkrithi inokuphuhlisa imicu yetsimbi kunye neentsinga zokwenziwa ezinokuphucula ukusebenza kwekhonkrithi kunye nokuphucula umgangatho wobunjineli boluntu.Eyangaphambili ifanelekile kumadama, izikhululo zeenqwelo-moya, i-High-speed Highway kunye nezinye iiprojekthi zinokudlala ukulwa nokuqhekeka, ukuchasana kwe-seepage, ukuxhathisa impembelelo kunye neempawu eziguquguqukayo, le yokugqibela inokuthintela ukuqhekeka kwangaphambili kwekhonkrithi, kwaye ikhusele umphezulu kwinqanaba lokuqala ukwenziwa kwezinto eziphathekayo.Ineempembelelo ezintle ekuthinteleni ukuqhekeka kwe-coating, ukuphucula ukugcinwa kwamanzi, ukuphucula ukuzinza kwemveliso kunye nokufaneleka kokwakhiwa, ukwandisa amandla, kunye nokuphucula ukunamathela kumphezulu.

Ithekhnoloji yeFiber isetyenziswa ngokubanzi kwiindlela ze-asphalt, ikhonkrithi, udaka, iimveliso zegypsum, isiponji somthi weplanga kunye namanye amasimi, iindawo zendlela kunye neendawo zokupaka kwiindawo ezishushu kunye nemvula;imiphezulu echasene nokutyibilika kweendlela zeenqwelo-moya, iindlela zedolophu, kunye neendlela ezihamba ngeendlela;indlela yabahambi ngebhulorho, ngakumbi ibhulorho yentsimbi yabahamba ngeenyawo;Imimandla yeAlpine, ukuthintela ukuqhekeka kweqondo lokushisa;Amacandelo endlela enzima yendlela, umthwalo onzima kunye namacandelo ezithuthi ezizele kakhulu;Ukudibana kweendlela zasezidolophini, izikhululo zebhasi, iiyadi zomthwalo, izikhululo zezibuko.
