Chidule:Pepalali likuwunikira chikoka ndi lamulo la cellulose ether pazinthu zazikulu za zomatira matailosi kudzera pakuyesa kwa orthogonal.Mbali zazikulu za kukhathamiritsa kwake zili ndi tanthauzo lina lothandizira kusintha zina za zomatira za matailosi.
Masiku ano, kupanga, kukonza ndi kugwiritsira ntchito cellulose ether m'dziko langa ndizotsogola padziko lonse lapansi.Kupititsa patsogolo ndi kugwiritsiridwa ntchito kwa cellulose ether ndiye chinsinsi cha chitukuko cha zipangizo zatsopano zomangira m'dziko langa.Ndikukula kosalekeza kwa zomatira matailosi komanso kukhathamiritsa kosalekeza komanso kuwongolera magwiridwe antchito, kusankha kwamitundu yogwiritsira ntchito matope pamsika watsopano wa zida zomangira kwalemeretsedwa.Komabe, momwe mungapititsire kukhathamiritsa kwakukulu kwa zomatira matayala kwakhala chitukuko cha msika womatira matayala.njira yatsopano.

2. Njira yoyesera ndi kusanthula zotsatira
Njira yoyesera yamphamvu yamakongoletsedwe imatanthawuza muyezo wa JC/T547-2005.Kukula kwa chidutswa choyesera ndi 40mm x 40mm x 160mm.Mukatha kupanga, mulole kuyimirira 1d ndikuchotsa mawonekedwewo.Amachiritsidwa m'bokosi la chinyezi kwa masiku 27, amamanga mutu wojambula ndi chipika choyesera ndi epoxy resin, kenako ndikuchiyika mu bokosi la kutentha ndi chinyezi pa kutentha kwa (23±2) °C ndi chinyezi chachibale cha ( 50 ± 5).1d, Onani chitsanzo cha ming'alu musanayese.Ikani makinawo pamakina oyesera amagetsi apakompyuta kuti muwonetsetse kuti kulumikizana pakati pa makinawo ndi makina oyesera sikupindika, kokerani chithunzicho pa liwiro la (250 ± 50) N/s, ndikulemba zoyeserera.Kuchuluka kwa simenti yogwiritsidwa ntchito pamayesowa ndi 400g, kulemera kwazinthu zina ndi 600g, chiŵerengero cha madzi-binder chimakhazikitsidwa pa 0.42, ndipo mapangidwe a orthogonal (3 zinthu, misinkhu 3) amatengedwa, ndipo zomwe zili mkati. wa cellulose ether, zomwe zili mu ufa wa rabara ndi chiŵerengero cha simenti ndi mchenga, malinga ndi zomwe zinachitikira kafukufuku wam'mbuyo kuti mudziwe mlingo weniweni wa chinthu chilichonse.
2.1 Zotsatira za mayeso ndi kusanthula
Kawirikawiri, zomatira za matailosi zimataya mphamvu zomangira zomangira pambuyo pa kumizidwa m'madzi.
Kuchokera ku zotsatira zoyesa zomwe zimapezedwa ndi mayeso a orthogonal, zitha kupezeka kuti kuchulukitsa kuchuluka kwa cellulose ether ndi ufa wa mphira kumatha kupititsa patsogolo mphamvu ya zomatira zamatayilo pamlingo wina, ndikuchepetsa chiŵerengero cha matope ndi mchenga kungachepetse mphamvu zake. kulimba kwa mgwirizano, koma zotsatira zoyesa 2 zopezedwa ndi mayeso a orthogonal sizingawonetse bwino momwe zinthu zitatuzi zimakhudzira mphamvu ya chomangira cha matailosi a ceramic ataviika m'madzi ndi chomangira cholimba pambuyo pa mphindi 20 zakuuma.Choncho, kukambirana za mtengo wochepa wa kuchepa kwa mphamvu zomangira zomangira pambuyo pa kumizidwa m'madzi kungasonyeze bwino chikoka cha zinthu zitatu zomwe zilipo.Mtengo wocheperako wa kuchepa kwa mphamvu umatsimikiziridwa ndi mphamvu yapachiyambi yomangirira ndi mphamvu yokhazikika pambuyo pa kumizidwa m'madzi.Chiŵerengero cha kusiyana kwa mphamvu ya chomangira ku mphamvu yapachimake yokhazikika chinawerengedwa.
Kusanthula kwa deta yoyesera kumasonyeza kuti poonjezera zomwe zili mu cellulose ether ndi ufa wa rabara, mphamvu yomangirira yomangiriza pambuyo pa kumizidwa m'madzi imatha kusintha pang'ono.Mphamvu yolumikizana ndi 0.3% ndi 16.0% kuposa ya 0.1%, ndipo kuwongolera kumawonekera kwambiri pamene kuchuluka kwa ufa wa rabara ukuwonjezeka;Pamene ndalamazo ndi 3%, mphamvu yogwirizanitsa imawonjezeka ndi 46.5%;pochepetsa chiŵerengero cha matope ndi mchenga, mphamvu yomangira yomizidwa m'madzi imatha kuchepetsedwa kwambiri.Mphamvu ya bond idatsika ndi 61.2%.Zitha kuwonedwa mwachidziwitso kuchokera ku Chithunzi 1 kuti pamene kuchuluka kwa ufa wa rabara kumawonjezeka kuchokera ku 3% mpaka 5%, chiwerengero cha kuchepa kwa mphamvu ya mgwirizano chikuwonjezeka ndi 23.4%;kuchuluka kwa cellulose ether kumawonjezeka kuchokera ku 0,1% mpaka 0.3%, mtengo wachibale wa kuchepa kwamphamvu kwamphamvu ukuwonjezeka ndi 7.6%;pamene mtengo wachibale wa kutsika kwa mphamvu ya bondi unakula ndi 12.7% pamene chiŵerengero cha matope ndi mchenga chinali 1: 2 poyerekeza ndi 1: 1.Pambuyo poyerekezera ndi chiwerengerocho, zitha kupezeka mosavuta kuti pakati pa zinthu zitatuzi, kuchuluka kwa ufa wa rabara ndi chiŵerengero cha matope ndi mchenga zimakhala ndi chikoka chodziwikiratu pa mphamvu yomangika ya kumiza kwa madzi.
Malinga ndi JC/T 547-2005, nthawi yowuma ya zomatira matailosi ndi yayikulu kuposa kapena yofanana ndi 20 min.Kuchulukitsa zomwe zili mu cellulose ether zitha kupangitsa kuti mphamvu zamakokedwe ziwonjezeke pang'onopang'ono pambuyo powulutsa kwa mphindi 20, ndipo zomwe zili mu cellulose ether ndi 0,2%, 0,3%, poyerekeza ndi zomwe zili 0,1%.Mphamvu zogwirizanitsa zidawonjezeka ndi 48.1% ndi 59.6% motsatira;kuonjezera kuchuluka kwa ufa mphira kungapangitsenso kumakoka chomangira mphamvu pang'onopang'ono kuwonjezeka pambuyo airing kwa 20mvula, kuchuluka kwa mphira ufa ndi 4%, 5% % poyerekeza ndi 3%, mphamvu chomangira chinawonjezeka ndi 19.0% ndi 41.4% motero;kuchepetsa chiŵerengero cha matope ndi mchenga, mphamvu yamakokedwe yomangika pambuyo pa mphindi 20 zowulutsa zidachepa pang'onopang'ono, ndipo chiŵerengero cha matope ndi mchenga chinali 1: 2 Poyerekeza ndi chiŵerengero cha matope cha 1: 1, mphamvu yamakokedwe yachitsulo imachepetsedwa ndi 47.4% .Poganizira kufunika kwa kuchepa kwa mphamvu zake zomangira zimatha kuwonetsa momveka bwino mphamvu ya zinthu zosiyanasiyana, kudzera pazifukwa zitatuzi, zitha kudziwika momveka bwino kuti kuchuluka kwa kuchepa kwa mphamvu yamakongoletsedwe amphamvu pambuyo pa mphindi 20 zowumitsa, pambuyo pa 20. Mphindi za kuyanika, zotsatira za chiŵerengero cha matope pa mphamvu zamakokedwe zomangira sizilinso zazikulu monga kale, koma zotsatira za cellulose ether zili zoonekeratu panthawiyi.Ndi kuchuluka kwa zomwe zili mu cellulose ether, mphamvu yake yocheperako imachepa pang'onopang'ono ndipo pamapindikira amakhala ofatsa.Zitha kuwoneka kuti cellulose ether imakhala ndi zotsatira zabwino pakukweza mphamvu yomangirira ya zomatira matailosi pakatha mphindi 20 zowuma.
2.2 Kutsimikiza kwa fomula
Kupyolera muzoyesera pamwambapa, chidule cha zotsatira za mapangidwe oyesera a orthogonal anapezedwa.
Gulu la osakaniza A3 B1 C2 ndi ntchito kwambiri akhoza kusankhidwa kuchokera chidule cha zotsatira za kapangidwe ka kuyesera orthogonal, ndiko kuti, zili pa cellulose etha ndi mphira ufa ndi 0,3% ndi 3%, motero, ndi chiŵerengero cha matope. ku mchenga ndi 1:1.5.
3. Mapeto
(1) Kuchulukitsa kuchuluka kwa cellulose ether ndi ufa wa mphira kumatha kukulitsa mphamvu yomata ya zomatira pamatayala pamlingo wina, ndikuchepetsa chiŵerengero cha matope ndi mchenga, mphamvu yomangirira imachepa, ndipo chiŵerengero cha matope ndi mchenga zotsatira za kuchuluka kwa cellulose ether pa mphamvu yamakokedwe ya zomatira matailosi a ceramic pambuyo pa kumizidwa m'madzi ndizofunika kwambiri kuposa kuchuluka kwa cellulose ether pa izo;
(2) Kuchuluka kwa cellulose ether kumakhala ndi chikoka chachikulu pamphamvu yolumikizira matailosi pambuyo pa mphindi 20 zowuma, zomwe zikuwonetsa kuti posintha kuchuluka kwa cellulose ether, zomatira za matailosi zitha kuwongolera bwino pakatha mphindi 20 zowuma.Pambuyo pa kutha kwa mgwirizano;
(3) Pamene kuchuluka kwa ufa wa rabara ndi 3%, kuchuluka kwa cellulose ether ndi 0.3%, ndipo chiŵerengero cha matope ndi mchenga ndi 1: 1.5, ntchito yomatira matayala ndi yabwino, yomwe ili yabwino kwambiri pa mayesero awa. .Kuphatikiza kwabwino kwa msinkhu.
