Kushandiswa kweHydroxyethyl Methyl Cellulose muSpray Mortar

Hydroxyethyl Methyl Cellulose (HEMC)i-cellulose ether isinganyunguduke mumvura ine hunyoro hwakanaka, inochengetedza mvura, inonyorova uye inoita mafirimu. Inoshandiswa zvakanyanya muzvinhu zvekuvaka, machira, makemikari ezuva nezuva nedzimwe nzvimbo. Mumakore achangopfuura, nekuvandudzwa kwemaindasitiri ekuvaka uye michina yekuvaka, spray mortar yakatsiva zvishoma nezvishoma kuvaka kwemaoko uye yakava nzira itsva yekuvaka inoshanda uye isingakuvadzi nharaunda. Kushandiswa kweHEMC mu spray mortar kwakavandudza zvakanyanya mashandiro ekuvaka uye mhando yechigadzirwa chemortar, uye ndeimwe yezvakakosha zvinowedzera mumunda uyu.

1. Pfupiso yeSpray Mortar

Dura rekupfapfaidza idura rakasanganiswa rakagadzirwa nemidziyo yekupfapfaidza, kusanganisira dura rekupurasita, dura rekuputira mafuta, dura rinozvienzanisa nedzimwe mhando. Kana tichienzanisa nekugadzirwa kwemaoko kwechinyakare, dura rekupfapfaidza rine zvakanakira zvekumhanya kwekuvaka nekukurumidza, simba shoma rekushanda, kunaka kwekuvaka kwakasimba, uye kwakakodzera kushanda munzvimbo huru. Zvisinei, nekuda kwekupfapfaidza nekukurumidza uye kuenderera mberi, zvinodiwa zvakanyanya zvinoiswa pakugona kushanda, kunamira uye kuchengetedza mvura kwedura.

2. Hunhu hwekushanda kweHEMC

Hydroxyethyl methylcellulose ine mapoka anoshanda ehydroxyethyl nemethoxy, izvo zvinoipa hunhu hwakanaka hunotevera:

Kunyungudika kwemvura kwakanaka uye kugadzikana: HEMC inonyungudika nekukurumidza mumvura inotonhora kuti igadzire mhinduro yakajeka kana inopenya, yakakodzera masisitimu akasiyana-siyana edhaka rakaoma.

Kuchengetedza mvura zvakanaka: Maumbirwo ayo emamorekuru anogona kuvharira hunyoro, kudzivirira hunyoro kuti husamhanye nekukurumidza, uye kuvandudza kunyorova nekunamatira kwedhaka panguva yekuvaka.

Wedzera kunamira uye kudzivirira kudonha: HEMC inopa simba rakakodzera rekubatanidza uye kusimba kwesimbi kudzivirira kudonha kwesimbi mushure mekupfapfaidza.

Kuvandudza mashandiro ekuvaka: Ita kuti dhaka rive rakapfava panguva yekupfapfaidza, kupomba uye kuenzana, uye kuvandudza mashandiro ekuvaka.

Yakagadzikana kusvika pakupisa, asidhi uye alkali: Yakakodzera mamiriro akasiyana ezvakatipoteredza kuti ive nechokwadi chekuti dhaka rinogara rakagadzikana.

3. Basa chairo reHEMC mupurasiti yekupfapfaidza

3.1. Kuvandudza hunhu hwekuvaka hwe rheological

Kushanda zvakanaka kwesimbi yekupfapfaidza kunoda kuti ive nekunyorova kwakanaka uye thixotropy yakagadzikana. HEMC inogona kugadzirisa kugadzikana kwesimbi yekupfapfaidza, zvichiita kuti zvive nyore kupomba nekupfapfaidza. Panguva imwe chete, inogona kukurumidza kukora mushure mekupfapfaidza pamadziro, kuvandudza mashandiro ekudzivirira kudzika, uye kuve nechokwadi chekuti simbi yekupfapfaidza yakafukidzwa zvakaenzana uye ukobvu hwekuvaka hwakaenzana.

3.2. Kuvandudza kuchengetwa kwemvura uye kuwedzera nguva yekuvhura

Munguva yekupfapfaidza, mvura inopfava nyore nyore, kunyanya kana paine tembiricha yakakwira kana mhepo inofefetera, izvo zvinogona kukonzera kuti dhaka ripwanyike kana kuti risabatanidzwe zvisina kunaka. Kushanda zvakanaka kweHEMC kuchengetedza mvura kunononoka kurasikirwa nemvura, kunoita kuti simende nezvimwe zvinhu zvinosimbisa simende zviwane mvura yakakwana, uye kunovandudza simba redhaka pakati pedhaka nehwaro. Panguva imwe chete, kuwedzera nguva yekuvhura kunobatsira pakuenzana kana kupedzisa, uye kunovandudza kuchinjika kwekuvaka.

3.3. Kuvandudza kudzivirira kudonha uye kubatana

Pakuvaka pamusoro pemadziro akamira kana pamadziro marefu, kana dhaka rakanyorova zvakanyanya, zviri nyore kudonha, zvichikanganisa chitarisiko nekudzora ukobvu. HEMC inowedzera viscosity uye kubatana kuti dhaka rive nethixotropy yakanaka, kureva kuti, rine kunyorova kwakanaka kana richimanikidzwa (kupomba kana kupfapfaidza), rinodzorera kugadzikana nekukurumidza kana risingamire, rinonamira zvakasimba pamadziro, uye rinodzivirira kudonha.

3.4. Kuvandudza kugadzikana kwesimbi

HEMC inogona kudzikamisa kupararira kwezvinhu zvinosimbisa simende uye zvinhu zvinosanganiswa mudura, kudzivirira kupatsanurwa uye kubuda kwemvura, kuve nechokwadi chekuti musanganiswa wedura wakafanana, uye kuvandudza kunaka kwekuvaka kwese.

4. Chipimo cheHEMC uye mashandisirwo azvo

Huwandu hunokurudzirwa hwekuwedzera muhari yekupfapfaidza hunowanzova 0.2% kusvika 0.6%, zvichienderana nefomura, chinangwa uye mashandiro anodiwa ehari. HEMC inowedzerwa muhari yakaoma muchimiro cheupfu hwakaoma, yakasanganiswa zvakaenzana nezvimwe zvinhu zvakabikwa, yobva yakurungwa nemvura kuti ishandiswe. Ine kunyungudika kwakanaka, iri nyore kupararira, haiburitse agglomeration, uye yakanakira kugadzirwa mumaindasitiri uye kushandiswa panzvimbo yacho.

5. Muenzaniso wemhedzisiro yekushandisa

Kushandiswa kweHEMC mupurasitiki yekupurasita pamadziro ekunze kunogona kuwedzera ukobvu hwemadziro uye kugona kwekuisa matope mupurasitiki, uye kuderedza kurasikirwa kwevhu rekuvaka. Mupurasitiki yekuputira, HEMC inovandudza simba rekubatanidza pakati pezvinhu nechigadziko, zvichiita kuti system yekuputira thermal ive yakasimba uye igare kwenguva refu. Mhinduro chaiyo yepurojekiti inoratidza kuti purasitiki yekupuruzira ine HEMC yakawedzerwa iri nyore kugadzira, mhedzisiro yacho inotsvedza uye inonyorova, uye mwero wekugadzirisa pakuvaka wakaderera.

Se cellulose ether ine mashandiro akanaka kwazvo,hydroxyethyl methylcellulose inoita basa guru mukuwedzera kukora uye kuchengetedza mvura, kugadzikana uye rubatsiro rwekuvaka mudhaka rekupfapfaidza, zvichivandudza zvakanyanya mashandiro ekupfapfaidza nekugadzirwa kwedhaka. Nekusimudzirwa kwekushandisa otomatiki mukuvaka uye kuvaka kwakasvibira, kushandiswa kweHEMC mumunda wedhaka rakasanganiswa kuchawedzera, zvichiva kukurudzira kukuru mukufambira mberi kwetekinoroji yezvinhu zvekuvaka.
