Methyl Hydroxyethyl Cellulose (MHEC), chinhu chinowanzo shandiswa mu cellulose ether muzvinhu zvekuvaka, chinoshandiswa zvakanyanya mumamortars akasanganiswa ne dry-mix, tile adhesives, putty powders, uye thermal insulation mortars nekuda kwekukora kwayo, kuchengetedza mvura, uye kugona kushanda. Mainjiniya mazhinji ane hanya nemubvunzo unokosha pakushandisa MHEC: Ndeipi dosi inokurudzirwa yeMHEC mumortar yesimende?
1. Chiyero Chinokurudzirwa cheMHEC muCement Mortar
Kazhinji, mwero wekuwedzera MHEC kumota yesimbi wakaderera, asi unogona kuvandudza mashandiro emota zvakanyanya. Zvichienderana neruzivo rweindasitiri uye data rehunyanzvi, chiyero chinokurudzirwa chinowanzo kuve:
Dura resimende rakajairika: rinenge 0.2‰–0.6‰ (kureva, magiramu 200–600 patani yeupfu hwakaoma).
Kupurasita dhaka nedhaka rekugadzira: kazhinji zviri pakati pe0.3‰–0.5‰.
Zvigadziko zvesimbi zvinodzivirira kupisa kana zvigadziko zvesimbi: zvingadiwa kuti pave nechiyero chakakwira zvishoma, chingangoita 0.4‰–0.7‰. Chinonamira mataira kana zvigadziko zvine simba guru: Chiyero chinogona kuwedzerwa kusvika pa0.6‰–1.0‰ kana zvichidikanwa, asi hazviwanzopfuura 1%.
Zvinofanira kucherechedzwa kuti chiyero cheMHEC chinokurudzirwa hachisi chinhu chakagadzika uye chinokanganiswa nezvinhu zvakaita sekugadzirwa kwemota, rudzi rwesimende, kupfava kwefiller, tembiricha yemhepo uye hunyoro. Saka, mukugadzirwa chaiko, chiyero chakakodzera chinowanzo tsanangurwa kuburikidza nemiedzo yekuedza.
2. Zvinhu Zvinokanganisa Chipimo Chinokurudzirwa
2.1. Rudzi rwesimende uye Chiyero
Kushanda uye kupfava kwesimende, pamwe chete nehuwandu hwezvinhu zvakasanganiswa (zvakaita seash inobhururuka neupfu hwemineral), zvese zvinokanganisa chiyero chakakodzera cheMHEC. Mamortar ane basa rakawanda uye anoshandisa mvura yakawanda anowanzoda cellulose ether yakawanda kuti achengetedze mvura.
2.2. Hunhu hwejecha nekuzadza
Kupararira kwehukuru hwejecha uye kupfava kwaro zvinokanganisa zvakanyanya kudiwa kwemvura. Jecha rakapfava kana kuti madhaka ane zvinozadza zvakareruka zvinowanzoda kuwedzerwa kweMHEC kuti zvirambe zvakagadzikana uye zvichishanda zvakanaka.
2.3. Nzvimbo yekuvaka
Munzvimbo dzine tembiricha yakakwira, hunyoro hushoma, kana mhepo ine simba, hunyoro hwemumarara hunokurumidza kupera, zvichiita kuti pave neMHEC yakawanda kuti mvura irambe ichichengetwa uye kuti nguva yekuvhura iwedzere.
2.4. Kushanda Kwakanangwa
Kana kuchengetwa kwemvura uye kuramba kudonha kwemvura kuri kwakakosha, chiyero chinogona kuwedzerwa zvine mwero.
Kana kushanda zvakanaka kuri iko kunonyanya kukosha, donhwe shoma rinokwana.
Pakushandisa zvinhu zvakatetepa (sezvinonamira mataira), kuwedzera MHEC zvakakodzera kwakakosha zvikuru.
3. Mhedzisiro yeMHEC muMortar
Kuwedzera MHEC zvine musoro kunogona kuvandudza zvakanyanya hunhu hwemortar, kusanganisira:
3.1. Kuchengetedzwa Kwemvura Kwakavandudzwa
Cellulose ether inoumba mhinduro yakafanana, ine simba mumota, ichinyatsovhara hunyoro uye ichidzivirira mvura isina kukwana yesimende, nokudaro ichiwedzera simba.
3.2. Kushanda Kwakavandudzwa uye Kushanda Kwakanaka
Dhaka rinova rakatsetseka uye rakanaka, zvichiita kuti zvive nyore kupararira, kuisa, uye kuomesesa panguva yekuvaka, zvichideredza kubuda ropa uye kupatsanurwa.
3.3. Kunamira Kwakawedzerwa uye Kuramba Kudonha
Pakuvaka kwakamira, dhaka harinyanyi kudonha uye rinoumba hukama hwakanaka nepamusoro pe substrate, masonry, kana insulation board.
3.4. Nguva Yakarebeswa Yekuvhura
MHEC inononotsa mwero wekubuda kwemvura mumota, zvichipa vashandi vekuvaka nguva yakawanda yekugadzirisa nekuvandudza mashandiro ekuvaka.
3.5. Kubudirira Kwakavandudzwa Kwese Kwese Kwekuumba Mari
Izvi zvinosanganisira kuramba kutsemuka, kugara kwenguva refu, uye kunaka kwenzvimbo yacho, zvichiita kuti dhaka rive rakasimba uye rakagadzikana mushure mekuoma.
4. Mazano Ekushandisa
Ongorora Usati Wawedzera Kuyera: Nekuda kwemhando dzakasiyana dzemishonga, zvinokurudzirwa kuita bvunzo dzemurabhoritari kuti uone mwero wakakodzera.
Dzivisa Kushandisa Zvakanyanya: Kuwedzera MHEC zvakanyanya kunogona kukonzera kuti dhaka rive rakanyanya kusimba, zvichiita kuti zviome kuisa uye zvichitokanganisa simba.
Iva nechokwadi chekuti mvura yapararira zvakaenzana: Panguva yekusanganisa yakaoma, iva nechokwadi chekuti MHEC yakasanganiswa zvakanaka nejecha nesimende kudzivirira kuungana kwevhu.
Chipimo chinokurudzirwa cheMHECMudhaka resimende rinowanzova pakati pe0.2‰ ne0.6‰, nedhaka remhando yepamusoro rinobvumira kuwedzera kwakakodzera kusvika pa0.7‰ kusvika pa1.0‰. Chiyero chaicho chinofanira kugadziriswa zvichienderana nerudzi rwedhaka, hunhu hwezvinhu zvakagadziriswa, uye nzvimbo yekuvaka. Kushandiswa kwakakodzera kweMHEC hakungogadzirisi chete kuchengetedza mvura yedhaka, kushanda zvakanaka, uye mashandiro ekuvaka, asiwo kunowedzera simba rekubatana uye kugara kwenguva refu. Ichi chinhu chakakosha mukugadzirwa kwemadhaka ekuvaka emazuva ano.
