Isidingo sokwengeza i-cellulose ku-mortar kanye nemikhiqizo esekelwe ku-gypsum

Imikhiqizo eyenziwe ngodaka ne-gypsum iyisici esibalulekile embonini yezokwakha, esebenza njengama-ejenti abophayo ezinto zokwakha ezihlukahlukene. Le mikhiqizo iba nokuqanjwa kabusha okuqhubekayo kanye nokuthuthukiswa ukuze kuhlangatshezwane nezidingo ezihlala zivela zokwakhiwa kwesimanje. Isengezo esisodwa esibalulekile kulezi zinto i-cellulose, edlala indima ebalulekile ekuthuthukiseni ukusebenza kwazo kanye nezakhiwo.

Ukuqonda Cellulose:

I-Cellulose iyi-polysaccharide eyenzeka ngokwemvelo etholakala ezindongeni zamaseli ezitshalo. Iyipolymer ephilayo egcwele kakhulu eMhlabeni futhi isebenza njengesakhi esiyisisekelo ezicutshini zezitshalo. Ngokwekhemikhali, ama-molecule e-cellulose ahlanganisa amaketanga aqondile amayunithi e-glucose axhunywe ndawonye ngamabhondi e-β(1→4) e-glycosidic. Lesi sakhiwo samangqamuzana esiyingqayizivele sinikeza amandla angavamile, ukuzinza, nokuqina ku-cellulose.

Embonini yezokwakha, i-cellulose ithola ukusetshenziswa okubanzi njengesengezo ezintweni zokwakha ezihlukahlukene, kuhlanganise nodaka kanye nemikhiqizo esekelwe ku-gypsum. Ukufakwa kwayo kufeza izinhloso eziningi, ukubhekana nezinselelo ezimbalwa okuhlangatshezwane nazo ngesikhathi sokukhiqiza, ukusetshenziswa, kanye nezigaba zokusebenza zalezi zinto.

Imisebenzi yeCellulose ku-Mortar kanye ne-Gypsum-based Products:

Ukugcinwa kwamanzi:
Omunye wemisebenzi eyinhloko ye-cellulose odakeni kanye nemikhiqizo esekelwe ku-gypsum yikhono layo lokugcina amanzi. Imicu ye-cellulose inamandla amakhulu okumunca nokubamba amanzi ngaphakathi kwesakhiwo sawo. Uma ingezwe kulezi zinto, i-cellulose isebenza njenge-ejenti yokugcina amanzi, iqinisekisa ukugeleza okwanele kwezingxenye ze-cementitious noma ze-gypsum. Le nqubo ende ye-hydration ithuthukisa ukusebenza kwengxube, ivumela ukusetshenziswa okungcono nokunamathela okuthuthukisiwe kuma-substrates.

Ukusebenza Okuthuthukisiwe Nokubumbana:
Ukuba khona kwemicu ye-cellulose ku-mortar kanye nemikhiqizo esekelwe ku-gypsum kuthuthukisa ukusebenza nokubumbana kwazo. Izintambo ze-cellulose zisebenza njenge-ejenti yokuqinisa, zihlakaza ngokuphumelelayo kuyo yonke ingxube futhi zenze inethiwekhi ye-three-dimensional. Le nethiwekhi iqinisa i-matrix, ivimbela ukuhlukaniswa futhi ithuthukise ukuhambisana okuphelele nokufana kwezinto. Ngenxa yalokho, ingxube iba lula ukuphatha, ukusabalala, kanye nokuma, okuholela ekusebenzeni okuthuthukisiwe phakathi nemisebenzi yokwakha.

Ukuvimbela I-Crack kanye Nokulawula Ukuncipha:
Enye indima ebalulekile ye-cellulose kulezi zinsiza ukufaka isandla ekuvimbeleni ukuqhekeka nokulawula ukushwabana. Phakathi nezigaba zokomisa nokuphulukisa, imikhiqizo eyenziwe ngodaka kanye ne-gypsum isengozini yokuncipha nokuqhekeka ngenxa yokulahlekelwa umswakama kanye nokucindezeleka kwangaphakathi. Amafayili e-cellulose asiza ukunciphisa lezi zinkinga ngokunikeza ukuqiniswa kwangaphakathi nokunciphisa ukwakheka kwama-micro-crack. Ngokuthuthukisa amandla okuqina kanye ne-ductility yezinto, i-cellulose ithuthukisa ukumelana kwayo nokuqhekeka okubangelwa ukuncipha, ngaleyo ndlela kukhuthaze ukuqina kwesikhathi eside kanye nobuqotho besakhiwo.

Izakhiwo Zemishini Ethuthukisiwe:
Ukuqiniswa kwe-cellulose kunikeza izakhiwo ezithuthukisiwe zemishini kudaka kanye nemikhiqizo eyenziwe nge-gypsum. Ukwengezwa kwamafayibha e-cellulose kukhulisa amandla ezinto eziguquguqukayo neziqinile, ukumelana nomthelela, nokuqina. Lokhu kuthuthukiswa ekusebenzeni komshini kunenzuzo ikakhulukazi ezinhlelweni zokusebenza lapho okokusebenza kungaphansi kwemithwalo yesakhiwo, amandla angaphandle, noma izici zemvelo. Ngokuqinisa i-matrix nokunciphisa ingozi yokwehluleka, i-cellulose ithuthukisa ukusebenza okuphelele nokuphila isikhathi eside kwesakhiwo esiphelile.

Ukuhambisana Nezinqubo Eziqhubekayo:
I-Cellulose itholakala emithonjeni evuselelekayo efana ne-wood pulp, ukotini, noma iphepha eligaywe kabusha, okulenza lizinze ngokwemvelo futhi livumelane nemvelo. Ukusetshenziswa kwayo emikhiqizweni yodaka kanye ne-gypsum kuhambisana nokugcizelela okukhulayo kwemboni ezinkambisweni zokwakha ezisimeme kanye nezinhlelo zokwakha eziluhlaza. Ngokuhlanganisa izithasiselo ze-cellulose, abakhiqizi banganciphisa ukuthembela kwabo ezinsizeni ezingavuseleleki futhi banciphise umthelela wemvelo wemikhiqizo yabo. Lokhu kuhambisana nezinqubo ezizinzile kugcizelela futhi isidingo se-cellulose ezintweni zokwakha zesimanje.

Ukwengezwa kwe-cellulose odakeni kanye nemikhiqizo esekelwe ku-gypsum akuyona nje indaba yokuzikhethela kodwa isidingo esiqhutshwa isidingo sokusebenza okuthuthukisiwe, ukuqina, nokusimama. I-Cellulose inikeza inqwaba yemisebenzi, okuhlanganisa ukugcinwa kwamanzi, ukusebenza okuthuthukisiwe, ukuvimbela ukuqhekeka, nokuqinisa imishini. Izakhiwo zayo eziyingqayizivele nokuhambisana nezinqubo ezizinzile ziyenza ibe isithasiselo esibalulekile ezintweni zokwakha zesimanje. Njengoba imboni yezokwakha iqhubeka nokuthuthuka, ukubaluleka kwe-cellulose ku-mortar kanye nemikhiqizo esekelwe ku-gypsum kuzokhula kuphela, kubumba ikusasa lezinqubo zokwakha ezizinzile neziqinile.
