Cellulose etrars, mongamethyl cellulose (MC),hydroxyethyl cellulose (hec),hydroxypropyl methyl cellulose (hpmc), ndipoCarboxymethyl cellulose (cmc), amagwiritsidwa ntchito mokwanira monga matope matope chifukwa cha kuthekera kwawo kosintha, kusungidwa kwamadzi, komanso kutsatira. Izi ndizofunikira kwambiri kupanga mabongo apamwamba kwambiri, piya maphepo, ndi matope matope, chilichonse chomwe chimakwaniritsa zosiyanasiyana pomanga. Kuchuluka kwa cellulose ether komwe kumaphatikizidwa m'matope kumatengera momwe mungafunire komanso momwe amafunira.
Gome 1: cellulose ether ether m'matalemba osiyanasiyana
| Mtundu wa matope | Ntchito yoyamba | Cellulose ether | Zotsatira za cellulose ether |
| Matope a anti-crack | Imalepheretsa kusokonekera chifukwa cha shrinkage kapena kupsinjika | 0.2% - 0,5% mwa kulemera | Kumathandizanso kugwirira ntchito, kumawonjezera kusungidwa kwamadzi, komanso kumathandiza. Kuchepetsa kusokonekera pakuchiritsa. |
| Plaster matope | Ntchito zokutira kukhoma kapena denga | 0.3% - 0,8% mwa kulemera | Amasintha bwino ntchito, imathandizira kutsatira magawo a magawo, ndipo imawonjezera nthawi yotseguka. |
| Matonge matope | Ntchito kuyika njerwa kapena miyala | 0.1% - 0.3% ndi kulemera | Zimathandizira kugwirira ntchito, kumalepheretsa tsankho, ndikusintha. |
1.Matope a anti-crack:
Matope a anti-crack amapangidwa makamaka kuti achepetse mapangidwe omwe akuchirikiza ndi magawo owuma a matope. Ming'alu iyi imatha kuchitika chifukwa cha zinthu ngati shrinkage, kuwonjezeka kwa mafuta, kapena zipsinjo zakunja. Cellulose eder ndiofunika kuti alepheretse kusinthasintha kwa matonthozo ndi kusungidwa kwamadzi. Makina wamba a celluse omwe atsutsana ndi matope a matope pakati pa 0,2% mpaka 0,5% mwa kulemera.
Ntchito za cellulose ether mu matope oletsa:
Kusungidwa kwamadzi: Cellulose ether imathandizira kusunthira madzi osakaniza matope, omwe amachepetsa njira yochepetsera ndikuwonetsetsa pang'onopang'ono. Izi zimachepetsa mwayi wokhala ndi vuto chifukwa choyanika.
Kukhazikika Kugwira Ntchito: Kuwonjezera kwa ethel ethel ether kumasintha matope, kumapangitsa kuti ikhale yosavuta kugwiritsira ntchito ndikufalikira. Izi zimapangitsa kuti malo osungunuka.
Kukana kukana: Mwa kusintha zomwe zimapangitsa kuti matope azikhala ndi matope, cellulose etters eder imathandizira kuphatikizidwa kwanyumba, kuchepetsa kumene kumachitika ming'alu yolimba.
Mu ntchito iyi, gawo la Etherse silokhalokhalo komanso zojambula zokha, zimathandiza kukulitsa mkwiyo waukulu komanso nthawi yayitali ya matope.
2.Plaster matope:
Plaster matope amagwiritsidwa ntchito pophimba malo monga makhoma ndi madenga. Imapangidwa kuti ithe kumaliza bwino ndikupanga malo olimba kuti kukongoletsa kwina kapena kutetezedwa. Cellulose exered ophatikizidwa ndi maphepo a pulaili omwe ali ndi 0,3% mpaka 0.8% mwa kulemera, kutengera machitidwe omwe akufuna.
Ntchito za cellulose ether mu matope a neya:
Chosangalatsa: Matayala a Pilani amafunikira katundu wamphamvu wotsatsa kuti atsimikizire kuti akugwirizana moyenera kumodzi mwamphamvu, kaya ndi njerwa, konkriti, kapena gypsum. Cellulose ether imathandizira kukulitsa ubalewu.
KugwirisetsaKuwonjezera cellulose ether ether kumawonjezera pulasitiki ya matope, kupangitsa kuti ikhale yosavuta kuyika bwino. Zimathandizira kuti woyang'anira akhale bwino, ngakhale osachita khama.
Nthawi yotseguka: Nthawi yotseguka kapena nthawi yogwira ntchito ya pulasitiya imanena kuti matope atakhala okhwima bwanji atagwiritsidwa ntchito. Cellulose amathandizira kuwonjezera nthawi yotseguka, kulola nthawi yambiri kusinthitsa ndi kusalala zisanachitike.
Kusungidwa kwamadzi: Zofanana ndi matope opha matope, cellulose emal eyeliul amathandizira kusunga madzi osungira, omwe Edzi oyenera hydration wa binder, motero amalimbikitsa mapangidwe ake olimba.
Kwa matope a netar, cellulose eders ndiofunikira magwiridwe antchito ndi kumaliza. Amadziwonetsetsa matope omwe alibe otanganidwa nthawi yayitali, kuthandiza akuluakulu amagwiritsa ntchito bwino zinthuzo, ngakhale pamalo okulirapo.
3.Matonge matope:
Matope matonge amagwiritsidwa ntchito makamaka ngati njerwa, miyala, kapena miyala limodzi. Udindo wake ndi kupanga chokhacho cholimba, cholimba cholimba mtima kwambiri cha makoma ndi zina zomanga. Cellulose ether mu mandote matonge imakhala yotsika, kuyambira 0,1% mpaka 0.3% ndi kulemera kotere, monga chidwi chachikulu mu mphamvu ndi mphamvu yogwirizira kapena kusungidwa kwamadzi.
Ntchito za cellulose ether mu matope matope:
Kugwirisetsa: Ngakhale matongete matope adapangidwa kuti akhale olimba, amafunikanso kukhala othandiza mokwanira kuti athe kugwiritsa ntchito ntchito, makamaka poika njerwa kapena miyala. Cellulose eders zimapangitsa kuyenda kwa matope popanda kunyalanyaza mphamvu zake.
Kupewa kusankhana: M'mapulogalamu a Masoni, makamaka ndi tinthu tating'onoting'ono kapena tinthu tating'onoting'ono tosiyanasiyana, tsankho (kulekanitsa (kulekanitsa kwa tinthu tating'onoting'ono) zitha kukhala vuto. Cellulose amathandizanso kusakaniza yunifolomu, kuonetsetsa kuti mosasinthasintha.
Kulumikizana ndi Kutsatira: Kulumikizana mwamphamvu ndikofunikira kuti matongete agwire mayunitsi omangayi. Cellulose adyeretsani popereka zomatira zosafunikira popanda kufunikira kwa zinthu zamadzi kwambiri, zomwe zimatha kufooketsa kusakaniza.
Kukana kwa shrinkage: Ngakhale kuti kuchepera matope otsutsana ndi matope otsutsa, cellulose ether elvey amatengabe gawo pakuwongolera, makamaka pakuchiritsa, zomwe zingasokoneze mphamvu ndi kukhulupirika kwa mafupa am'mimba.
Pomwe zopezeka za cellulose mu mandote matonge ndi wotsika kuposa mativa ena, zomwe zimapangitsa kuti zithandizire matope ndi magwiridwe ake ndizofunikira. Imatsimikizira kuti matope amakhala osavuta kugwiritsa ntchito posungira makina ofunikira.
Cellulose earsNdizofunikira zowonjezera mu anti-stock, pulasitala, matope matope, ndikusewera maudindo ofunikira pakuwongolera kukonzanso, kusungidwa kwamadzi, kotsatira kukana. Zomwe zili mu cellulose ether ether zimasiyana kutengera mtundu wa matope ndi ntchito yake. Matope a anti-nthomba nthawi zambiri amakhala ndi kuchuluka kwa cellulose et (0.2% mpaka 0,5%) kuti apititse kusinthasintha ndikupewa ming'alu. Plaster matcher amafunika kugwirira ntchito mogwirizana ndi kutsatira, ndi ma cellulose elevar kuyambira 0,3% mpaka 0.8%. M'matope matope, zomwe zimapezeka zimachepetsa (0.1% mpaka 0.3%) koma zofunikanso kuti mugwiritse ntchito mogwirizana komanso kusasinthasintha.
Monga momwe miyezo yomangira imasinthira ndi kufunafuna zida zokhazikika, zolimbitsa thupi zolimbitsa thupi zimakula pomanga mafoni, kupereka njira zothandiza komanso zothandiza pa zovuta zomwe zimachitika.
