Cellulose ether ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito kwambiri popanga matope pomanga. Ndi mtundu wa zotumphukira za cellulose zomwe zimasinthidwa mwazinthu kudzera m'magulu a hydroxyl pama cellulose, kuphatikiza hydroxypropylmethylcellulose (HPMC), methylcellulose (MC), hydroxyethylcellulose (HEC), etc. Ma cellulose ethers awa ali ndi ntchito zosiyanasiyana komanso zinthu zabwino kwambiri, zomwe zimawapatsa mwayi wofunikira pakumanga matope.
(1) Kupititsa patsogolo ntchito yomanga
1. Kuwongolera magwiridwe antchito
Ma cellulose ethers amagwira ntchito ngati zokhuthala komanso zosunga madzi mumatope. Ikhoza kusintha mamasukidwe akayendedwe ndi thixotropy wa matope, kukhala kosavuta kufalitsa ndi yosalala, potero kuwongolera mayiko ndi dzuwa la zomangamanga. Kuphatikiza apo, ether ya cellulose imatha kuletsa matope kuti asapatuke panthawi yomanga, kuwonetsetsa kuti matopewo azikhala ofanana komanso kumamatira bwino kwa matope.
2. Sinthani kumamatira kwa matope
Ma cellulose ether amatha kusintha kwambiri kumamatira kwa matope ku gawo lapansi. Izi ndizofunikira kwambiri pamachitidwe monga kuyika matayala kapena pulasitala yomwe imafunikira mgwirizano wolimba ndi gawo lapansi. Ma cellulose ether amalola matope kuti azikhala ndi zomatira zabwino m'malo owuma kapena owuma, kupeŵa mavuto okhetsa ndi kusweka chifukwa cha kusamata kokwanira.
(2) Kupititsa patsogolo mphamvu ya matope
1. Konzani kasungidwe ka madzi
Kusungirako madzi ndi chimodzi mwazinthu zofunika kwambiri za cellulose ether, zomwe zimapangitsa kuti matope azikhala ndi chinyezi chokwanira asanaumitse. Khalidweli limatha kuletsa kutuluka msanga kwa madzi ndikuchepetsa kutayika kwa madzi mumtondo, potero kuwongolera kukwanira kwa simenti ya hydration ndikulimbikitsa kupititsa patsogolo mphamvu ndi kukhazikika kwa matope.
2. Konzani mphamvu ya matope
Kupyolera mu mphamvu yosungira madzi ya cellulose ether, simenti mumatope amatha kukhala ndi madzi okwanira kuti apange mankhwala amphamvu a hydration. Izi zimathandiza kupititsa patsogolo mphamvu ya compressive ndi flexural ya matope. Kuphatikiza apo, ether ya cellulose imathanso kuchepetsa ming'alu yomwe imayambitsidwa ndi kuchepa kwa matope panthawi yowumitsa ndikusunga mphamvu zonse ndi kukhazikika kwa matope.
3. Sinthani kukana kuzizira kwachisanu
Ma cellulose ethers amachulukitsa kuchulukana kwa matope, zomwe zimapangitsa kuti zisamve kuzizira. Kukana kuzizira kozizira kumeneku ndikofunikira makamaka kwa matope omwe amagwiritsidwa ntchito m'malo ozizira, omwe amatha kuwonjezera moyo wautumiki wa nyumbayo ndikuchepetsa ndalama zokonzera.
(3) Kupititsa patsogolo kusinthika kwa chilengedwe pomanga
1. Wonjezerani maola otsegulira
Ma cellulose ethers amatha kuwonjezera nthawi yotsegulira matope, ndiye kuti, nthawi yomwe matope amakhalabe ogwiritsidwa ntchito atayikidwa. Izi ndizopindulitsa makamaka pomanga kumalo otentha kwambiri kapena owuma, kuchepetsa vuto la kuuma msanga kwa matope komwe kumakhudza khalidwe la zomangamanga.
2. Sinthani kukana kwa sag
Pomanga pamalo oyima, matope amatha kutsetsereka kapena kugwa. Ma cellulose ether amawongolera magwiridwe antchito a matope a anti-sag kudzera mukukula, kuonetsetsa kuti matopewo amatha kumangika pamalo oyima ndikupewa kuwonongeka kwa zomangamanga.
(4) Phindu la chilengedwe ndi zachuma
1. Konzani kagwiritsidwe ntchito ka zinthu
Ma cellulose ether amatha kusintha kwambiri magwiridwe antchito ndi kapangidwe ka matope, ndikuchepetsa kuwonongeka kwa zinthu panthawi yomanga. Izi zili ndi phindu lalikulu pazachuma pa ntchito yomanga yaikulu, zomwe zingachepetse ndalama zakuthupi ndi kupititsa patsogolo phindu lachuma la zomangamanga.
2. Wokonda zachilengedwe
Ma cellulose ethers ndi zida zochokera ku bio ndipo sizikhudza kwambiri chilengedwe panthawi yopanga ndikugwiritsa ntchito. Kuonjezera apo, imatha kuchepetsa kuwonongeka kwachiwiri panthawi yomanga matope, monga fumbi ndi zinyalala, ndikukwaniritsa zofunikira za nyumba zamakono zobiriwira.
(5) Zitsanzo zenizeni za ntchito
1. Zomatira matailosi
Mu zomatira matailosi a ceramic, kuwonjezera kwa cellulose ether kumatha kupititsa patsogolo kugwirira ntchito, kusunga madzi ndi kulimba kwa zomatira, komanso kupititsa patsogolo kugwirizanitsa komanso kumanga bwino kwa matailosi a ceramic.
2. Pakhoma pulasitala matope
Ma cellulose ether mu pulasitala matope bwino operability ndi odana ndi sag ntchito ya matope, amaonetsetsa kusalala ndi pamwamba khalidwe la pulasitala wosanjikiza, ndi amachepetsa zomangamanga zolakwika ndi kukonza ntchito.
3. Mtondo wodziwikiratu
Ma cellulose ether mu matope odzipangira okha amathandiza kupititsa patsogolo madzi ndi kusunga madzi mumatope, kuwalola kuti azitha kusanja pansi ndikuwongolera kutsetsereka ndi kumanga bwino kwa nthaka.
Mwachidule, cellulose ether ili ndi ubwino waukulu pakugwiritsa ntchito ufa wamatope muzomangamanga. Izo osati bwino yomanga ntchito ndi thupi katundu matope, komanso bwino chilengedwe kusinthasintha ndi ubwino chuma zomangamanga. Kugwiritsidwa ntchito kwa cellulose ether kumapangitsa kuti matope omanga azikhala abwino komanso okhazikika komanso amalimbikitsa chitukuko chokhazikika cha ntchito zomanga. Ndi kupita patsogolo kosalekeza kwaukadaulo wa zomangamanga, cellulose ether idzakhala ndi mwayi wogwiritsa ntchito mumatope ndikukhala chinthu chofunikira komanso chofunikira pakupanga kwamakono.
