Cellulose ether imhando yepolymer zvinhu zvinogadzirwa nekemikari inogadzirisa serurosi chaiyo. Inoshandiswa zvakanyanya mukuvaka, mishonga, chikafu, machira, kutarisirwa kwevanhu uye mamwe minda. Iyo yakakosha molecular chimiro che cellulose ether inopa iyo yakawanda yakasarudzika zvivakwa uye saka ine mabhenefiti ari pachena uye mabhenefiti mumaindasitiri akawanda.
1. Kukora uye rheology kudzora
Chimwe chezvinhu zvinonyanya kukosha zve cellulose ethers kugona kwavo kukora. Mushure mekunyungudutswa mumvura, cellulose ether inogona kugadzira yunifomu colloidal mhinduro uye zvinobudirira kuwedzera viscosity yehurongwa. Izvi zvinoibvumira kuita basa rekugadzirisa fluidity uye kuvandudza kushanda kwezvinhu zvekuvaka (sedhaka, dhaka) uye machira. Nekugadzirisa kuyerwa uye rudzi rwe cellulose ether, akasiyana rheological properties anogona kuwanikwa kuti asangane nezvinodiwa zvakasiyana-siyana zvekushandisa. Semuenzaniso, mumatope ekuvaka, cellulose ethers inogona kudzivirira zvinhu kubva pakuparadzanisa panguva yekusanganiswa, kuve nechokwadi chekufanana kwezvinhu panguva yekuvaka uye kudzivisa kuputika kana kudonha.
2. Kuchengeta mvura
Imwe mukana wakakosha we cellulose ethers pakushandiswa kwavo kwakapararira mukuvaka kugona kwavo kwekuchengetedza mvura. Inogona kuvhara hunyoro mumisanganiswa yehupfu yakaoma senge simende uye gypsum, nekudaro ichinonotsa kubuda kwemvura muzvinhu. Kune simenti-based mortars uye gypsum-based materials, kuchengetwa kwemvura kwe cellulose ethers kunobatsira kuvandudza kushanda kwe hydration reaction, kuve nechokwadi chokuti zvinhu zvakapora zvakakwana uye zvakaomeswa, nokudaro zvichivandudza simba uye kusimba kwechivako. Panguva imwecheteyo, mukupisa kwepamusoro kana nzvimbo dzakaoma, kushandiswa kwemvura ye cellulose ether kunonyanya kukosha kudzivirira kuparara kwehutano hwekuvaka nekuda kwekurasikirwa kwemvura.
3. Mafirimu akanaka ekugadzira zvinhu
Cellulose ethers ine yakanakisa firimu-inogadzira zvimiro uye inoshandiswa zvakanyanya mukupfekwa uye zvinonamira. Inogona kuumba yunifomu uye dense firimu pamusoro pekuvhara pamusoro, iyo isina mvura, guruva uye anti-oxidation, ichiwedzera kutsetseka uye kusimba kwejasi. Mumachira ekuvaka, cellulose ethers inogona kuvandudza kunamatira uye kupfeka kuramba kwejasi uye kuwedzera hupenyu hwayo hwesevhisi. Mukuwedzera, iyo firimu-inogadzira zvinhu zve cellulose ethers yakakoshawo mukugadzirira kwemishonga, iyo inogona kubatsira zvinodhaka kuumba mabhaisikopo emufirimu kudzora kuburitswa kwezvinodhaka uye kuvandudza kugadzikana kwezvinodhaka.
4. Kupikisa kugadzirisa uye kumiswa
Mune zvigadziriso zvemvura zvakadai semajasi uye emulsions, cellulose ether inogona kushandiswa seyakagadzikana inobudirira kudzivirira kugadzirisa kwezvimedu zvakasimba. Inovandudza kugadzikana kwechigadzirwa uye kushandiswa nekuwedzera viscosity yezvinwiwa uye kuchengetedza yunifomu kugoverwa kwezvimedu zvakasimba. Semuenzaniso, mumapendi emvura, cellulose ethers inogona kudzivirira zvakanyanya kunaya kwemavara kana mafirita, chengetedza yunifomu yepende uye kuvandudza kutsetseka kwekuvaka.
5. Kuvandudza kusimba kwekubatana
Muminda yekuvaka uye yekunamatira, kushandiswa kwe cellulose ethers kunogona kunyatso kuvandudza kusimba kwekubatana kwezvinhu, kunyanya mumapolymer-modified mortars. Basa rayo sechinhu chakakora uye chekuchengetedza mvura chinogona kusimbisa hukama pakati pedhaka uye nheyo yezvinhu. Iko kunamatira kwedhaka kunoderedza kutsemuka uye shrinkage matambudziko edhaka. Cellulose ethers inogonawo kunyatsogadzirisa nguva yekuvhura yekunamatira, kuve nechokwadi chekuti nguva yakakwana yekugadzirisa uye kucheka panguva yekuvaka.
6. Kuvandudza kushanda kwekuvaka
Cellulose ethers zvakare inovandudza zvakanyanya zvivako zvekuvaka zvakasiyana-siyana zvekuvaka, kunyanya mumatope esimende uye gypsum-based materials. Rheology yaro inovandudza zvakanyanya kusunda, kutsvedza uye nyore kushanda panguva yekuvaka. Vashandi vekuvaka vanogona kushandisa zvinhu zviri nyore uye kuderedza kunamatira kwemidziyo uye kutambisa zvinhu. Kushandiswa kwe cellulose ether kunovandudzawo maitiro e-anti-sag ezvinyorwa, kuve nechokwadi kuti pasi mushure mekuvakwa kwakanyatsonaka uye kwakanaka.
7. Kudzivirira kwekushisa kwepamusoro uye kugadzikana kwemakemikari
Cellulose ether ine kugadzikana kwakanaka kwekushisa uye kusagadzikana kwemakemikari, iyo inobvumira kuchengetedza maitiro ayo emuviri nemakemikari pasi pemamiriro akasiyana-siyana. Cellulose ethers inogona kunyatso ramba kuderedzwa mukupisa kwakanyanya, acid-base kana oxidizing nharaunda, kuve nechokwadi chekugara kwavo uye kuvimbika mukuvaka, indasitiri yemakemikari, mishonga uye mamwe minda. Hunhu uhu hunoitawo kuti cellulose ethers ishandiswe zvakanyanya mumashandisirwo anoda kusimba kwakanyanya sekuchera oiri uye kuvaka kudzivirira mvura.
8. Biocompatible uye isina chepfu
Cellulose ethers makomisheni anobva kucellulose yechisikigo uye anoshandiswa zvakanyanya mumaindasitiri ezvemishonga uye ezvechikafu nekuda kwekunaka kwavo kuenderana uye kusiri kwehupfu. Sezvishandiso zvemishonga, cellulose ethers inogona kugadzirisa kuburitswa kwezvinodhaka uye kunatsiridza kugadzikana kwezvinodhaka. Iwo anogona zvakare kushandiswa seanokora, stabilizers, uye gelling agents mukugadzira chikafu kuti ive nechokwadi chekunaka uye kugadzikana kwechigadzirwa.
9. Kuchengetedzwa kwezvakatipoteredza uye kuberekazve
Cellulose ethers inotorwa kubva kune yakasikwa cellulose, inova sosi inogona kudzokororwa, uye maitiro ayo ekugadzira uye mashandisiro anoenderana nenharaunda. Izvi zvinoita kuti ive sarudzo yakanaka kutsiva mamwe echinyakare ekugadzira makemikari, kunyanya nhasi nekukura kuri kudiwa kwezvinhu zvinogara uye zvine hushamwari. Kushandiswa kwe cellulose ethers kunoenderana nekusimudzira maitiro ekuchengetedzwa kwezvakatipoteredza uye green chemistry.
10. Yakasiyana-siyana yekushandisa
Izvo zvakasiyana-siyana zve cellulose ethers zvakakonzera kuwanda kwekushandiswa mumaindasitiri akawanda. Semuenzaniso, muindasitiri yekuvaka, inoshandiswa muakaoma-musanganiswa dhaka, ceramic tile adhesives, kunze kwemadziro emadziro masisitimu, nezvimwewo; muindasitiri yemishonga, cellulose ether inowanzoshandiswa inodzorwa inoburitsa mumiririri uye inonamira; muindasitiri yezvekudya, iyo Inoshandiswa seyakakora, stabilizer uye gelling agent. Mukuwedzera, cellulose ethers inoitawo basa rakakosha mumigodhi yemunda wemafuta, zvizoro uye zvigadzirwa zvemakemikari zvemazuva ese.
Cellulose ether chinhu chakasiyana-siyana chepolymer chine zvakawanda zvakanaka sekukora, kuchengetedza mvura, kugadzira firimu, kudzikamisa, uye kunamira kwakawedzera. Kushandiswa kwaro mukuvaka, mishonga, chikafu uye mamwe minda haisi kungovandudza mashandiro echigadzirwa uye mhando, asiwo inosangana nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba. Nekufambira mberi kwetekinoroji uye nekuwedzera kwendima dzekushandisa, cellulose ethers ichaita basa rinowedzera kukosha mune ramangwana.
