Cellulose ether ndiyo inonyanya kuwedzera yejasi rakanamwa gypsum, iro rinoita basa rakakosha muchiedza chakapuramwa gypsum. Kurudyi hakune hanya nekupurasita iyo yekutanga cellulose ether HPMC zvigadzirwa, inogona kukurumidza kupinda mukati memarudzi ese ezvigadzirwa zvegypsum uye haiburitse masumbu, porosity yekupurasita gypsum mushure mekurapa pasina kukanganisa, kuitira kuti ive nechokwadi chekufema kwekuita gypsum. , kunonoka kuita asi kwete kune pesvedzero pamakristasi egypsum akakura, aine simba rakanyorova reviscous kuti ive nechokwadi chekubatanidza zvinhu, pahwaro hwepamusoro Kuvandudza mashandiro ekuvaka kwezvigadzirwa zvegypsum, zvichiita kuti zvive nyore kupararira pasina kunamatira kune zvishandiso.
Sezvamunoziva mose, mumakore achangopfuura, nekuvandudzwa kwenyika uye kugadzirisa mitemo, kuvandudzwa kwezvakasvibirira zvekuchengetedza zvivakwa zvekuvaka zvave nzvimbo inopisa, sezvo indoor plastering zvinhu zvitsva, kuputira gypsum kuri kuwedzera kusimbiswa, kuisa gypsum iri kuwedzera. kutsiva simende dhaka rezvinhu zvitsva zvekuchengetedza simba, kuchengetedza kwezvakatipoteredza, hupfumi, zvese simba resimende, uye zvichienzaniswa nesamende ine hutano kuchengetedzwa kwezvakatipoteredza, yakasimba, Simba rekunamatira rakakura, hazvisi nyore kuita upfu, kwete kutsemuka, kwete chinhu. dhiramu, kwete kudonhedza hupfu uye zvimwe zvakanakira, nyore kushandisa, mari yekuchengetedza, chiedza plaster gypsum inonyanya kukavakirwa pakuvaka plaster upfu sechinhu chikuru, kuvhenekesa perlite kana girazi mabheji sekubatanidzwa, kuwedzera zvakasiyana-siyana zvepurasita zvinhu.
Cellulose ether Ine zvinotevera zvakanakira:
Chekutanga, gadzirisa humidity yemhepo, kana hunyoro hwekunze huchikwira kupfuura hunyoro hunoenderana neplaster plaster, nekuti iyo yekunze mhute yekumanikidza yakakwira kupfuura iyo yakazara mhute pressure, inosimudzira kushanda kwemukati kwekushambadza kwemvura, kuitira kuti kunonoke kusimuka kwemvura. humidity; Kana hunyoro hwekunze hwadzikira pane hunyoro hunowirirana hwegypsum yakapuramwa, mhute yekunze inodzikira pane yakazara mhute pressure, zvichiita kuti mamorekuru emvura abude mukati. Naizvozvo, inogona kuita basa rekugadzirisa uye kudzora humidity.
Chechipiri, inobudirira murazvo retadancy. Iyo molecular huremu hwe dihydrous gypsum ndeye 172, uye molecular huremu hwemvura ndeye 18. Kana imba ye 100m2 inosangana nemoto, kana tembiricha yasvika 110 ℃ kana pamusoro, dihydrous gypsum inokurumidza kuburitsa mvura yekristaro kuita semihydrous gypsum uyezvezve shanduko. mune anhydrous gypsum, iyo inogona kuburitsa 560kg yemvura. Mvura inogona kutora kupisa kwakawanda mukubuda kwemhepo. Inogona kudzivirira zvinobudirira kukurumidza kukwira kwekamuri tembiricha uye kuvandudza mikana yekupukunyuka.
Chechitatu, kuchengetedzwa kwezvakatipoteredza kwakasvibirira. Gypsum mushure mekurapwa kusingakuvadzi, haina zvinosvibisa zvinonyungudika, kushandiswa kweiyo inorganic gel zvinhu, zvinowedzera zvigadzirwa zvekuchengetedza zvakatipoteredza, yakagadzirwa nemwenje plaster gypsum haiburitse formaldehyde nezvimwe zvinhu zvinokuvadza, girinhi kuchengetedzwa kwezvakatipoteredza, chengetedzo uye zorora.
Chechina, kudzivirira kupisa, kuchengetedza simba, kupfekwa kwenzwi, kupikisa simba. Thermal conductivity yekupurasita plaster ndeye 0.17W / (MK), saka iyo yekupisa yekuputira plaster ndeye 20% yechinyakare simende plastering dhaka, iyo ine imwe yekupisa yekudzivirira uye inogona kuderedza kushandiswa kwesimba kwezvivakwa. Plastering gesso iri mu condense process, iyo yemukati inoburitsa diki gap, nekuti izvi zvinogona kudzikisira kumanikidza kwekurira, zvinogona kudzivirira simba remutsindo kuti riite zvakare, rinogona kushandura simba rekurira kuita simba rekupisa, kuve neruzha rwakanaka rwekudzivirira kuita. Nekuda kweiyo porous chimiro mushure me condensation, inogona kunyatso tora simba rekuita, saka haizotsemuka nekudonha kana ichinge yabatwa.
Kunamira gypsum ne cellulose ether kunonyanya kuve neanotevera maitiro:
1, chivakwa chakanakisa: kukwenya nyore, kutsetseka, kunogona kuumba, nepurasitiki.
2, kunatsiridza plaster mortar coating rate: ichienzaniswa neyakafanana cellulose ether, coating rate yakawedzera zvakanyanya.
3, yakanakisa anti-droop performance: gobvu layer scraping single building haiyerere yakarembera, kanopfuura kaviri (kupfuura 3cm) kukwenya hakudonhe, yakanakisa plastiki.
4, yakanakisa yekuchengeta mvura mwero: kurebesa nguva yekushanda kwegypsum base, kuvandudza mamiriro ekunze egypsum base, kuwedzera kusimba kwechisungo chegypsum base uye chigadziko, yakanakisa kunyorova kwekubatanidza kuita, kuderedza pasi madota.
5, kuwirirana kwakasimba: kwakakodzera kumarudzi ose egypsum base, kuderedza nguva yekukwegura kwegypsum, kuderedza kuomeswa kwe shrinkage rate, rusvingo haisi nyore kubvisa chigubhu, kuputika.
6, munda wekushandisa uye huwandu: yakareruka pasi plaster gypsum, inokurudzirwa dosage 0.18% - 0.25%.
Plastering gypsum ne cellulose ether inogadzirwa nemhando yepamusoro yakanatswa donje ne etherification reaction, isiri-ionic cellulose ether, yakagadzikana yemuviri zvivakwa, haizobudise kemikari inopindirana nezvimwe zvinhu mbishi uye kugadzira zvimwe zvinokuvadza, zvakatipoteredza, hazvina kukanganisa hutano hwevanhu, mukupura gypsum imhando yegirinhi simba rekuchengetedza ekuwedzera, KIMA yagara iri pfungwa yegirinhi kuchengetedza kwezvakatipoteredza uye kuchengetedza simba muzvigadzirwa zvekambani uye manejimendi, isu tinokurudzira budiriro inoenderera, mukupindura kudana kwenyika, makomo akasvibira igoridhe nesirivha. makomo, KIMA ichashandisa zviri nani cellulose ether zvigadzirwa kubatsira nyika kugadzira yakasvibira kuchengetedza kwezvakatipoteredza mukati memadziro epurasita zvinhu.
