I-cellulose fiber ekwakhiweni

Imicu yokwakha ebalulekile yile: 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 yezici ze-cellulose ngokwayo, njenge-hydrophilicity yemvelo, amandla okubamba kahle kakhulu, indawo enkulu ye-fiber ethize, nokuqina okuphezulu namandla, njll., ngemva kokwengezwa kukhonkolo, ngaphansi kwesenzo sokucwiliswa kwamanzi namandla angaphandle, iyakha. Inombolo enkulu yezintambo ezinhle ezisatshalaliswa ngokulinganayo zingavimbela ngokuphumelelayo ukuvela kwemifantu ebangelwa ukuncipha kwepulasitiki, ukuncipha okomile kanye nokushintsha kwezinga lokushisa kukakhonkolo, futhi kuthuthukise kakhulu izakhiwo zemishini kakhonkolo.

Imicu ye-Cellulose yenza usimende ube manzi ngokuphelele, unciphise kakhulu i-voids kukhonkolo, futhi wenze ukhonkolo ube denser, ngaleyo ndlela uthuthukise ukumelana nesithwathwa, ukungena kwamanzi, kanye ne-chloride ion permeability kakhonkolo, futhi unika ukhonkolo ukuqina okungcono.

(1) Umphumela wokunqanda ukuqhekeka kukhonkolo

Imicu yeCellulose isatshalaliswa ngezinhlangothi ezintathu kukhonkolo, enganciphisa ngempumelelo ukugxiliswa kwengcindezi ekugcineni kwe-micro-cracks, yenza buthaka noma iqede ukucindezeleka okuqinile okubangelwa ukushwabana kukakhonkolo noma udaka, futhi kuvimbele ukwenzeka nokwandiswa kwemifantu emincane.

(2) Thuthukisa ukungagxili kukakhonkolo

Ukusatshalaliswa komfaniswano wemicu ye-cellulose kukhonkolo kwakha uhlelo olusekelayo, oluvimbela ukuhlukaniswa kwamanzi angaphezulu kanye nokuxazululwa kwama-aggregates, kunciphisa ukopha kukakhonkolo, kunciphisa imigudu yokuphuma kwegazi kakhonkolo, futhi kunciphisa kakhulu i-porosity kukhonkolo, ngakho-ke Ukungakwazi ukhonkolo uthuthukiswa kakhulu.

(3) Thuthukisa ukumelana nokuncibilika kokuqhwaza kukakhonkolo

Ngenxa yobukhona bemicu ye-cellulose kukhonkolo, inganciphisa ngempumelelo ukugxiliswa kwengcindezi eqinile kukhonkolo ebangelwa imijikelezo eminingi yokuqandisa, futhi ivimbele ukunwetshwa okwengeziwe kwemifantu emincane.Ngaphezu kwalokho, ngenxa yokuthuthukiswa kokungangenisi kukakhonkolo, kuyazuzisa futhi ukuthuthukisa ukumelana kwayo neqhwa.

(4) Thuthukisa ukumelana nomthelela kanye nokuqina kukakhonkolo

Izintambo ze-cellulose zisiza ukubamba umsebenzi wezingxenye zekhonkrithi lapho zithinteka, futhi ngenxa yomphumela wokumelana nokuqhekeka kwezintambo, lapho ukhonkolo ubhekene nemithwalo yomthelela, izintambo zingavimbela ukwanda okusheshayo kwemifantu yangaphakathi, ngakho-ke ingathuthukisa ngokuphumelelayo. ukumelana komthelela wokhonkolo nokuqina.

(5) Ukuthuthukiswa kokuqina kokhonkolo

Ngenxa yomphumela omuhle wokumelana nokuqhekeka kwezintambo ze-cellulose, ukuvela nokuthuthukiswa kwemifantu kuyancipha kakhulu, futhi ukunciphisa i-porosity yangaphakathi kunciphisa ukugqwala nokungena komswakama endaweni yangaphandle kanye nemidiya yamakhemikhali, usawoti we-chloride, njll. kwinani elikhulu lokuqhekeka Kuncishisiwe, ukubola kokuqiniswa okuyinhloko kwesakhiwo kuyancipha, ukuze ukuqina kokhonkolo kuthuthukiswe kakhulu futhi kuthuthukiswe.

(6) Ukuthuthukiswa kokumelana nokushisa okuphezulu kokhonkolo

Ngokhonkolo, ikakhulukazi ukhonkolo wamandla aphezulu, i-cellulose fiber yengezwa, ngoba iqukethe inani elikhulu le-fiber monofilaments esabalaliswe ngokufanayo, eveza ukusatshalaliswa okungahleliwe okungama-dimensional amathathu futhi yakha isakhiwo senethiwekhi esinezinhlangothi ezintathu.Lapho izinga lokushisa langaphakathi lelungu likakhonkolo elibhakwa ngamalangabi lenyuka laya ku-165 Lapho izinga lokushisa lingaphezu kuka-℃, imicu iyancibilika futhi yakhe iziteshi ezixhumene ngaphakathi ukuze isitimu esinamandla sokucindezela okukhulu siphume ngaphakathi kukakhonkolo, ukuze sikwazi ukugwema ukuqhuma. endaweni yomlilo futhi uthuthukise kakhulu ukuqina kokhonkolo.

I-anti-seepage kanye ne-anti-crack fiber ingathuthukisa amandla nokusebenza okunqanda ukubonwa kwekhonkrithi.Inhlanganisela yobuchwepheshe be-fiber kanye nobuchwepheshe obukhonkolo kungathuthukisa imicu yensimbi nemicu yokwenziwa engathuthukisa ukusebenza kukakhonkolo futhi ithuthukise ikhwalithi yobunjiniyela bomphakathi.Owokuqala ulungele amadamu, izikhumulo zezindiza, umgwaqo ohamba ngesivinini esiphezulu kanye namanye amaphrojekthi angadlala ukulwa nokuqhekeka, anti-seepage, ukumelana nomthelela kanye nezakhiwo eziguquguqukayo, lokhu kungavimbela ukuqhekeka kukakhonkolo kusenesikhathi, futhi kuvikele ingaphezulu ekuqaleni kwesigaba sokuqala. ukukhiqizwa kwezinto ezibonakalayo.Inemiphumela emihle ekuvimbeleni ukuqhekeka kwe-coating, ukuthuthukisa ukugcinwa kwamanzi, ukuthuthukisa ukuzinza kokukhiqiza nokufaneleka kokwakhiwa, ukwandisa amandla, nokuthuthukisa ukunamathela phezulu.

Ubuchwepheshe be-fiber busetshenziswa kabanzi emigwaqweni ye-asphalt, ukhonkolo, udaka, imikhiqizo ye-gypsum, isiponji se-wood pulp nezinye izinkambu, izindawo zomgwaqo kanye nezindawo zokupaka ezindaweni ezishisa kakhulu nezinemvula;izindawo ezimelene nokushibilika kwemigwaqo, imigwaqo yasemadolobheni kanye nemigwaqo emikhulu;indawo egandaywayo yedekhi yebhuloho, ikakhulukazi indawo egandayiwe yebhuloho lensimbi;Izifunda ze-Alpine, ukuvimbela ukuqhekeka kokushisa;Izingxenye zethrafikhi ezisindayo zomgwaqo, imithwalo esindayo kanye nezingxenye zezimoto ezigcwele ngokweqile;Izimpambano zemigwaqo yasemadolobheni, iziteshi zamabhasi, amayadi wezimpahla, amatheminali.
