Methyl Hydroxyethyl Cellulose (MHEC)imhando ye nonionic cellulose ether inoshandiswa zvakanyanya mumakemikari ekuvaka. Inoratidza kunaka kwekukora, kuchengetedza mvura, kugadzira mafirimu, kubatana, uye kuparadzira, zvichiita kuti ive chinhu chakakosha mumortars dzakasanganiswa nedry-mix, tile adhesives, putty powders, gypsum-based materials, uye coating systems.
1. Kudzora Kukora uye Kudzora Kukora kweMaronda
Muzvinhu zvakagadzirwa nesimende negypsum, MHEC inokora nekugadzira hydrogen bonds nemamorekuru emvura, zvichiwedzera viscosity yemushonga. Hunhu uhwu hunovandudza kuyerera uye kushanda kwetsvina, zvichidzivirira kupatsanurwa kana kubuda ropa panguva yekusanganisa nekushandisa. Muma tile adhesives neputty powders, kuwedzerwa kweMHEC kunoita kuti zvinhu zvive nyore kuisa, kunogadzira nzvimbo yakafanana, uye kunovandudza kushanda zvakanaka kwekuvaka.
2. Kuchengetwa kwemvura uye Kunonoka Kuoma
Chimwe chezvinhu zvinonyanya kuzivikanwa neMHEC ndechekuchengetedza kwayo mvura zvakanaka. Panguva yekuvaka simende nezvigadzirwa zvegypsum, kupwanyika kwemvura nekukurumidza kunogona kukonzera kusasimba kwakakwana, kutsemuka, kana kudzikira kwekunamatira. MHEC inoumba firimu remamorekuru rakafanana mukati mehurongwa, ichideredza kupwanyika kwemvura uye ichivimbisa kunyoroveswa kwemvura yakakwana uye kuomarara kwegypsum, nokudaro ichisimudzira simba rekupedzisira uye kugara kwenguva refu kwechinhu chacho. Hunhu uhwu hunonyanya kukosha munzvimbo dzinopisa, dzakaoma dzekuvaka.
3. Kushanda Kwakanaka
MHEC inovandudza zvakanyanya kushanda kwemakemikari ekuvaka. Inowedzera kunyorova kwedhaka, zvichiita kuti rive rakapfava panguva yekukwesha nekukwesha, inoderedza kuramba kwekuvaka uye simba rekushanda. Uyezve, nekuda kwehunhu hwayo hwethixotropic, MHEC inochengetedza kunyorova kwakanyanya kana isingachinji panguva yekuvaka, ichidzivirira kudonha kana kudonha. Kana ikaiswa pasi pesimba rekunze, kunyorova kwayo kunoderera, zvichiita kuti kushandiswa uye kupararira kuve nyore. Kugadziriswa uku kwerheological kunowedzera zvakanyanya ruzivo rwekuvaka.
4. Kusimba Kwakavandudzwa kweBond
Muzvinamatiro zvemataira, masisitimu ekudzivirira madziro ekunze, uye zvinamatiro zvinozvienzanisa, MHEC inovandudza kuchengetedza mvura uye kugona kunyorova kwechinhu ichi, ichisimbisa kunamira kwacho pahwaro nezvinhu zviri pamberi. Kuwedzera MHEC kune chinonamatiro chemataira kunoita kuti mataira agare kwenguva yakakwana panguva yekuisa, zvichidzivirira kuvharika kana kudonha nekuda kwekurasikirwa nemvura nekukurumidza. Uyezve, kunyorova kwakafanana mukati mechinhu ichi kunowedzera simba rekubatana, zvichiita kuti chivakwa chive chakasimba uye chakachengeteka.
5. Kuvandudza Kukwanisa Kuchinja Kwemamiriro Ekunze uye Hunhu Hwepamusoro
MHEC inobatsira kugadzira chimiro chakafanana uye chakasimba pamusoro pevhu mumasisitimu edhaka nependi, zvichideredza mukana wekutsemuka. Mumapudhi eputty uye machira ekunze emadziro, MHEC inowedzera hunhu hwekugadzira firimu uye kutsetseka, zvichikonzera kuti madziro ave akatsetseka uye akanaka uye ichipa hwaro hwakanaka hwemachira anotevera. Uyezve, inovandudza kuramba kwechando-kunyunguduka uye kuramba kwemamiriro ekunze kwehurongwa, ichivimbisa kushanda kwakasimba mumamiriro ekunze akasiyana-siyana.
6. Mienzaniso yeKushandisa
Zvinonamira Mataira neGrouts: MHEC inoita kuti zvinonamira mataira zvirambe zvichichengetwa nemvura uye zvishande zvakanaka, zvichiita kuti zvirambe zvichishanda kwenguva refu uye zvichivandudza simba rezvisungo.
Upfu hwePutty nezvinhu zvinoenzanisa madziro: MHEC inowedzera kutsetseka uye kuchengetedza mvura panguva yekukwesha, kudzivirira kutsemuka nekupwanyika. Zvigadzirwa zvakagadzirwa neGypsum: Zvakadai seplaster inoenzanisa gypsum uye gypsum putty: MHEC inovandudza kushanda nesimba, ichidzivirira kurasikirwa nemvura nekukurumidza.
Dura rekudzivirira madziro ekunze: Rinovandudza kushanda kwedura, kuchengetedza mvura, uye kuramba kudonha, zvichiita kuti sisitimu irambe yakasimba.
Dhaka rakasanganiswa nemvura: Rinoshandiswa zvakanyanya mudhaka rekugadzira masonry, dhaka replaster, uye kugadzirisa dhaka, zvichiita kuti dhaka rishande zvakanaka.
Kupenda kwekuvaka: MHEC inokora, inoparadzira, uye inosimbisa kupendesa kwakavakirwa mumvura senge pendi yelatex, zvichivandudza kushanda kwayo uye kunaka kwefirimu.
7. Kuenzanisa nedzimwe Cellulose Ethers
Mukushandiswa kwemakemikari ekuvaka, MHEC inowanzo enzaniswa neHPMC (hydroxypropyl methylcellulose). Kunyange zvazvo zviviri izvi zvine hunhu hwakafanana, MHEC inopa kunyungudika kuri nani uye kushanda zvakanaka kwemari, zvichiita kuti ive yakakodzera kushandiswa kunonyanya kudhura. HPMC, kune rumwe rutivi, inoratidza kuramba kwakanyanya kupisa uye kugara kwenguva refu. Saka, mumafomu chaiwo, MHEC kana HPMC, kana musanganiswa wezvose zviri zviviri, inowanzo sarudzwa zvichibva pane zvinodiwa pakuvaka uye kufunga nezvehupfumi kuti iwane mhedzisiro yakanaka.
Sechinhu chakakosha chekuwedzera makemikari pakuvaka,MHEC, ine hunhu hwayo hwakakwana hwekukora, kuchengetedza mvura, kushanda zviri nani, kunamira kwakawedzerwa, uye kuramba kuripo kwemamiriro ekunze kwakawedzerwa, yave ichishandiswa zvakanyanya mumhando dzakasiyana-siyana dzekushandiswa, kusanganisira matiles anonamira, putty powders, gypsum products, insulation mortars, uye coatings. Haingogadzirise hunhu hwezvinhu zvekuvaka chete asiwo inowedzera kushanda zvakanaka kwekuvaka uye mhando yeprojekiti yekupedzisira. Sezvo zvinhu zvekuvaka zvichiramba zvichichinja kuita zvinhu zvakasvibira, zvine hushamwari kune nharaunda, uye zvinoshanda zvakanyanya, mikana yeMHEC yekushandisa ichawedzera, uye chinzvimbo chayo chakakosha muindasitiri yemakemikari ekuvaka icharamba ichisimbiswa.
