Ama-cellulose ashers, asI-methyl cellulose (MC),I-Hydroxyyethyl cellulose (HEC),I-Hydroxypropyl methyl cellulose (HPMC), futhiI-Carboxymethyl Cellulose (CMC), kusetshenziswa kabanzi njengezengezo ekwakhekeni kodaka ngenxa yekhono labo elihlukile lokwenza ngcono ukusebenziseka, ukugcinwa kwamanzi, nokunamathela. Lezi zakhiwo zibalulekile ekukhiqizeni kodaka olusezingeni eliphakeme lokulwa nokulwa, kanye nodaka lwe-plaster, kanye nodaka lwama-masonry, ngakunye okusebenzela izinhloso ezahlukahlukene ekwakhiweni. Inani le-cellulose ether elifakwe ku-motar kuncike ekusebenzeni okufunayo kanye necala elithile lokusebenzisa.
Ithebula 1: okuqukethwe kwe-cellulose ether ku-donsa ehlukahlukene
| Uhlobo lodaka | Umsebenzi oyinhloko | Okuqukethwe kwe-cellulose ether | Umphumela we-cellulose ether |
| Udaka lokulwa ne-anti-crack | Kuvimbela ukuqhekeka ngenxa ye-shrinkage noma ingcindezi | 0.2% - 0.5% ngesisindo | Ithuthukisa umsebenzi, inyusa ukugcinwa kwamanzi, futhi ithuthukise ukunamathela. Kunciphisa ukuqhekeka ngesikhathi sokuphulukisa. |
| Udaka ngodaka | Isetshenziselwa izindonga noma ophahleni | I-0.3% - 0.8% ngesisindo | Kuthuthukisa ukusebenziseka kalula kwesicelo, kuthuthukisa ukunamathela ku-substrates, futhi kwandise isikhathi esivulekile. |
| Udaka kaMasonry | Isetshenziselwe ukubeka izitini noma amatshe | 0.1% - 0.3% ngesisindo | Ithuthukisa ukusebenzela, kuvimbela ukwahlukaniswa, futhi kuthuthukise ukubopha izibopho. |
1.Udaka lokulwa ne-anti-crack:
Udaka lokulwa nokulwa nodonga luhlelwe ngokukhethekile ukunciphisa ukwakheka kwemifantu ngesikhathi sokuphulukisa nokukhula ngezigaba zodaka. Le mifantu ingavela ngenxa yezinto ezinjenge-shrinkage, ukwanda okushisayo, noma izingcindezi zangaphandle. I-Cellulose Afers ibalulekile ekuvimbeleni izindaba ezinjalo ngokwandisa ukuguquguquka kodaka nokugcinwa kwamanzi. Okuqukethwe okujwayelekile kwe-cellulose ether yama-anti-crack udaka kusuka phakathi kuka-0.2% kuya ku-0.5% ngesisindo.
Imisebenzi ye-cellulose ether ku-anti-crack usimende:
Ukugcinwa kwamanzi: I-cellulose ether isiza ekugcinweni kwamanzi ku-dutar mix, ebambezela inqubo yokuhwamuka futhi iqinisekise izinga elihamba kancane nelilawulwa. Lokhu kunciphisa amathuba okuqhekeka komhlaba ngenxa yokomiswa okusheshayo.
Ukusebenza okwenziwe ngcono: Ukungezwa kwe-cellulose ether kuthuthukisa ukuvumelana kodaka, okwenza kube lula ukusebenzisa futhi kwasabalale. Lokhu kuphumela ekuqedeni okubushelelezi komhlaba.
Ukumelana: Ngokushintsha izakhiwo zesimbozo sodaka, izithambiso ze-cellulose zinikela ngokuxubana okuthe xaxa, kunciphisa ukwenzeka kokuqhekeka kwe-shrinkage ngesikhathi sesigaba esinzima.
Kulolu hlelo lokusebenza, iqhaza le-Cellulose ETHER alisebenzi kuphela kodwa futhi liyahlukahluka, lisiza ukuthuthukisa ukuqina okuphelele nokuphila isikhathi eside kodaka.
2.Udaka ngodaka:
Udaka ngodaka ngokuyinhloko usetshenziselwa ukumboza izindawo ezifana nezindonga nophahla. Yenzelwe ukunikeza ukuqeda okubushelelezi futhi kwakha indawo eqinile yokuhlobisa noma ukuvikelwa. I-Cellulose Afers ivame ukufakwa odongeni ngodaka ngamanani asuka ku-0.3% kuya ku-0.8% ngesisindo, ngokuya ngezimpawu zohlelo lokusebenza olufunayo.
Imisebenzi ye-cellulose ether e-Plaster Data:
Ukunamathela: Udaka ngodaka ludinga izakhiwo eziqinile zokunamathela ukuze uqinisekise ukuthi ziboshelwa kahle engxenyeni engaphansi, noma ngabe izitini, ukhonkolo, noma i-gypsum. I-cellulose ether isiza ukuthuthukisa lokhu kuhlanganisa.
Ukusebenza: Ukungeza i-cellulose ether kukhulisa i-plastiki kadaka, okwenza kube lula ukusebenzisa kahle. Kuyasiza abadlali bathola inhlawulo, ngisho nangaphezulu ngaphandle komzamo obalulekile.
Isikhathi esivulekile: Isikhathi esivulekile noma isikhathi sokusebenza sodaka ngodaka sibhekisele isikhathi eside ukuthi udaka luhlala isikhathi eside lapho selusetshenzisiwe. I-Cellulose Tathers isiza ukwandisa isikhathi esivulekile, ivumela isikhathi esithe xaxa sokushintsha nokubusheleleka ebusweni ngaphambi kokuba lukhuni.
Ukugcinwa kwamanzi: Kuyafana nohlobo lokulwa nohlobo lwe-anti-crack, i-cellulose ether iyasiza ekugcinweni kwamanzi, okusiza ekucebweni kwe-hydration efanelekile ye-binder, ngaleyo ndlela kukhuthaze ukwakheka kwendawo eqinile, eqinile.
Ngodaka ngodaka, izithambiso ze-cellulose zibaluleke kakhulu ekusebenzeni nasekuqedeni ikhwalithi. Baqinisekisa ukuthi udaka luhlala lusebenza esikhathini eseluliwe, ukusiza ababukeli basebenzise impahla ephumelelayo, ngisho nasezindaweni ezinkulu.
3.Udaka kaMasonry:
I-Masonry Mortar isetshenziswa ikakhulukazi izitini ezibophayo, amatshe, noma amabhlokhi ndawonye. Indima yayo ukudala isibopho esiqinile, esihlala isikhathi eside esiqinisekisa ubuqotho bezinhlekelele zodonga nezinye izinto zobumbano. Okuqukethwe kwe-cellulose ether ku-masonry udaka ngokujwayelekile, kusuka ku-0,1% kuya ku-0,3% ngesisindo, njengoba ukukhathazeka okuyisisekelo kulezi zinto kungamandla nokugcinwa kwamanzi esikhundleni sokusebenza noma ukugcinwa kwamanzi.
Imisebenzi ye-cellulose ether e-Masonry ngosimende:
Ukusebenza: Ngenkathi uMasonry Datar yakhelwe ukuba uqine, kufanele futhi asebenze ngokwanele ukuqinisekisa ukusetshenziswa kwesicelo, ikakhulukazi lapho ubeka izitini noma amatshe. AbakwaCellulose Abapholile bathuthukisa ukuhamba kodaka ngaphandle kokuyekethisa amandla alo.
Ukuvimbela Ukuhlukaniswa: Kuhlelo lokusebenza lwe-masonry, ikakhulukazi ngezinhlanganisela zama-coarse noma osayizi bezinhlayiyana ezinkulu, ukuhlukaniswa (ukuhlukaniswa kwezinhlayiya ezinhle kusuka ku-coarser) kungaba yinkinga. I-Cellulose Tashers isiza ukugcina umfaniswano wokuxuba, uqinisekise ikhwalithi nokusebenza okungaguquki.
Ukubopha kanye nokunamathela: Ukubopha okuqinile kubalulekile ku-masonry wombuzane ukubamba amayunithi ama-maronry ndawonye. I-Cellulose Tathers isiza ekuhlinzekeni ukukhanyisa okudingekayo ngaphandle kwesidingo sokuqukethwe kwamanzi ngokweqile, okungakwenza buthaka ukuxubana.
Ukumelana neShrinkage: Noma kubaluleke kakhulu ku-masonry ngodaka kunokwakheka kokulwa, i-cellulose ether isadlala indima ekulandiseni i-shrinkage, ikakhulukazi ngesikhathi sokuphulukisa, esingabeka phansi amandla nobuqotho bamalunga we-masonry.
Ngenkathi okuqukethwe kwe-cellulose ether ku-masonry ngodaka kuphansi kunakwamanye ama-donsa, ithonya laso ekusebenzikeni kukadaka nasekusebenzeni kusebalulekile. Kuqinisekisa ukuthi udaka luhlala lulula ukusebenzisana ngenkathi lugcina izakhiwo ezidingekayo zemishini zokubopha izibopho.
I-Cellulose AfersZiyizengezo ezibalulekile ku-anti-crack, udaka, kanye nodaka lwama-masonry, edlala izindima ezibalulekile ekwenzeni ngcono ukusebenza, ukugcinwa kwamanzi, ukunqwabelanisa, kanye nokumelana nokuqhekeka. Okuqukethwe okuthile kwe-cellulose etr kuyahlukahluka ngokuya ngohlobo lodaka nohlobo lwayo oluhlosiwe. Ukulwa nodaka ngokujwayelekile kuqukethe ukugxila okuphezulu kwe-cellulose kanye ne-0.2% kuya ku-0.5%) ukuthuthukisa ukuguquguquka nokuvimbela imifantu. Udaka ngodaka ludinga ukulinganisela kokusebenza kanye nokunamathelisa, nge-cellulose ether okuqukethwe ngokujwayelekile kusuka ku-0.3% kuya ku-0.8%. Ku-Masonry Masonrars, okuqukethwe kuvame ukwehla (0,1% kuya ku-0.3%) kepha kunzima ukusebenziseka nokuvumelana okufanayo.
Njengoba amazinga wokwakha avela futhi afunela imali ehlala isikhathi eside, ukusebenza kahle kokusebenza okuphezulu, indima ye-cellulose tifers ekwakhiweni kodaka izoqhubeka ukwandisa, inikeze izixazululo ezisebenza kahle nezizinzile zezinselelo ezijwayelekile ezibhekene nalo mkhakha.
