Focus on Cellulose ethers

Ordinary mukati memadziro putty paste

1. Mhando uye kusarudzwa kwezvinhu zvakasvibirira zveyakajairwa putty paste

(1) Heavy calcium carbonate

(2) Hydroxypropyl Methyl Cellulose Ether (HPMC)

HPMC ine high viscosity (20,000-200,000), mvura yakanaka solubility, hapana tsvina, uye nani kugadzikana kupfuura sodium carboxymethylcellulose (CMC). Nekuda kwezvinhu zvakaita sekudzikiswa kwemutengo wezvinhu zvakakwira kumusoro, kuwanda, uye kwakawedzera kukwikwidza kwemusika, mutengo wemusika weHPMC Sezvo uchiwedzerwa muhuwandu hushoma uye mutengo hauna kunyanya kusiyana neiyo yeCMC, HPMC inogona kushandiswa pachinzvimbo cheCMC. kuvandudza kunaka uye kugadzikana kweakajairika putty.

(3) Chirimwa-mhando inorasika polymer hupfu

dispersible polymer poda imhando yepamusoro yechirimwa-based dispersible polymer powder, ine hunhu hwekuchengetedza kwezvakatipoteredza uye hutano, kugadzikana kwakanaka, kusachembera, uye yakakwirira yekubatana simba. Iyo yakayerwa yekubatanidza simba reiyo aqueous mhinduro ndeye 1.1Mpa pakusangana kwe10%. .

Kugadzikana kweRDP kwakanaka. Muedzo une aqueous solution uye yakavharwa bvunzo yekuchengetera yeaqueous solution inoratidza kuti mhinduro yayo ine aqueous inogona kuchengetedza kugadzikana kwekutanga kwemazuva 180 kusvika kumazuva 360, uye hupfu hunogona kuchengetedza kugadzikana kwekutanga kwemakore 1-3. Naizvozvo, RDP -2 Hunhu uye kugadzikana ndizvo zvakanakisa pakati peazvino polymer hupfu. Iyo yakachena colloid, 100% inonyungudika mumvura, uye isina tsvina. Inogona kushandiswa seyepamusoro-mhando mbishi zvinhu zveyakajairwa putty poda.

(4) Madhaka ekutanga diatom

Gomo rekuzvarwa diatom dope rinogona kushandiswa kugadzira dzvuku dzvuku, mwenje yero, chena, kana yakareruka girinhi zeolite poda yepakutanga diatom dhaka pachayo, uye inogona kugadzirwa inoyevedza ine mavara-inonatsa putty paste.

(5) Fungicide

2. Kugadzira formula yeyakajairwa yemhando yepamusoro yemukati madziro putty paste

Raw material zita Reference dosage (kg)

Normal tembiricha mvura yakachena 280-310

RDP 7

Hydroxypropyl methylcellulose (HPMC, 100000S) 3.5

Heavy calcium powder (200-300 mesh) 420-620

Primary diatom dhaka 100-300

Mvura-based fungicide 1.5-2

Cherechedza: Zvichienderana nebasa uye kukosha kwechigadzirwa, wedzera huwandu hwakakodzera hwevhu, shell powder, zeolite powder, tourmaline powder, barite powder, nezvimwewo.

3. Zvigadzirwa zvekugadzira uye teknolojia

(1) Kutanga kusanganisa RDP, HPMC, heavy calcium powder, primary diatom mud, etc. nemusanganisi wakaoma wehupfu uye uise parutivi.

(2) Panguva yekugadzirwa kwakarongeka, tanga wawedzera mvura kumusanganisi, wobva wawedzera mvura-based fungicide, batidza musanganisi wakasarudzika weputty paste, zvishoma nezvishoma isa poda yakasanganiswa mumusanganisi, uye kurunga uchiwedzera kusvika hupfu hwese hwapararira. kuita yunifomu paste state.

4. Zvido zvehunyanzvi uye tekinoroji yekuvaka

(1) Grassroots zvinodiwa

Isati yavakwa, chigadziko chepasi chinofanirwa kunyatsogadziriswa kubvisa madota anoyangarara, mavara emafuta, kusununguka, kuputika, kuputika, uye kuputika, uye kuzadza nekugadzirisa mhango uye makatsemuka.

Kana kupfava kwemadziro kwakashata, yakakosha anti-crack mortar yemadziro emukati inogona kushandiswa kuyera madziro.

(2) Tekinoroji yekuvaka

Manual plastering: chero base base layer iri madziro esimende akanyatsoti sandarara, asina hupfu, mavara emafuta, uye guruva rinoyangarara, anogona kukweshwa kana kutsikwa.

Ukobvu hwekupurasita: Hukobvu hwepurasita yega yega hunosvika 1mm, iyo inofanirwa kuve yakatetepa kwete kukora.

Kana jasi rekutanga raoma kusvika risina kunamira, wozoisa rechipiri. Kazhinji, jasi rechipiri rinopona.

5. Nyaya dzinoda kutarisirwa

(1) Izvo zvinorambidzwa zvachose kuisa putty isingapinde mumvura kune yakajairwa putty mushure mekukwesha kana kupukuta yakajairika putty.

(2) Mushure mekunge iyo yakajairwa putty yakaoma zvachose, iyo latex pendi inogona kupendwa.

(3) Ordinary putty poda haigone kushandiswa munzvimbo dzinowanzo rima uye dzine hunyoro senge zvimbuzi, dzimba dzepasi, dzimba dzekugezera, kugeza mota, madziva ekutuhwina, uye makicheni.
