Kuvaka zvinhu giredhicellulose etherchinhu chakakosha chinoshanda chemakemikari chinowedzera, chinoshandiswa zvakanyanya mukuvaka zvinhu, senge simende, kongiri, dhaka rakaoma, nezvimwe.
1. Chimiro chemakemikari uye kupatsanurwa
Cellulose ether inhengo yepolymer inoumbwa nekugadziriswa kwemakemikari echisikigo cellulose. Chikamu chayo chikuru iboka rehydroxyl re cellulose rakagadziridzwa ne etherifying agent (yakadai sevinyl chloride, acetic acid, nezvimwewo). Zvinoenderana neakasiyana etherifying mapoka, inogona kupatsanurwa mumhando dzakasiyana dze cellulose ethers, kunyanya kusanganisira hydroxypropyl methylcellulose (HPMC), hydroxyethyl cellulose (HEC) uye methyl cellulose (MC).
2. Kuchengeta mvura
Zvishandiso zvekuvaka giredhi cellulose ether ine yakanakisa yekuchengetedza mvura zvivakwa, izvo zvinogona zvinobudirira kuvandudza simba rekuchengetedza mvura redhaka nekongiri. Izvi zvinowedzera kushanda kwezvinhu panguva yekuvaka uye zvinoderedza kutsemuka uye kurasikirwa kwesimba kunokonzerwa nekubuda kwemvura.
3. Kukora
Cellulose ether ine yakanaka thickening properties, iyo inogona kuvandudza fluidity uye viscosity yezvinhu zvekuvaka, zvichiita kuti zvive nyore kushanda panguva yekuvaka. Kukora kunobatsira kuvandudza kugadzikana kwezvinhu uye kudzivirira stratification uye sedimentation.
4. Kuderedza mvura
Kusvika kumwero wakati,cellulose ethersinogona kuderedza kuwanda kwemvura mukongiri kana dhaka, nekudaro ichivandudza simba uye kusimba kwezvinhu. Ichi chimiro chinoita kuti chive chakakosha mukushandiswa kwekongiri yepamusoro.
5. Kuita kwekuvaka
Zvivako zvekuvaka zvine cellulose ethers zvine kushanda kuri nani panguva yekuvaka, izvo zvinogona kuwedzera nguva yekuvaka uye kuderedza matambudziko ekuvaka anokonzerwa nekuomeswa. Uye zvakare, ivo vanogona zvakare kuvandudza kunamatira kwedhaka uye kuwedzera kunamatira kwezvinhu zvekupfeka.
6. Mutswe kuramba
Cellulose ethers inogona kuvandudza kutsemuka kwedhaka nekongiri uye kuderedza kutsemuka kunokonzerwa nekushanduka kwetembiricha kana kuomeswa kwemvura. Izvi zvakakosha pakugadzikana kwenguva refu uye aesthetics yezvivakwa.
7. Kugadzirisa uye kuenderana
Zvekuvaka giredhi cellulose ethers zvine kuenderana kwakanaka neakasiyana ezvivakwa zvekuvaka uye zvinogona kusanganiswa nesimende, gypsum, mapolima uye zvimwe zvinongedzo pasina kukanganisa kuita kwavo. Uku kuchinjika kunoita kuti cellulose ethers ishandiswe zvakanyanya muindasitiri yekuvaka.
8. Kuchengetedzwa kwezvakatipoteredza
Sezvo raw materials yecellulose ethersinotorwa kubva kumiti yemiti, ivo pachavo vane humwe hunhu hwekudzivirira kwezvakatipoteredza. Kuenzaniswa nemamwe mapolymer ekugadzira, cellulose ether inonyanya kuenderana nemamiriro ekunze mukushandiswa uye kuraswa kwemarara.
9. Minda yekushandisa
Kuvaka zvinhu giredhi cellulose ether inoshandiswa zvakanyanya mumhando dzakasiyana dzekuvaka, kusanganisira:
Dry mortar: senge bonding dhaka, plastering dhaka, nezvimwe.
Concrete: kunyanya kongiri yepamusoro.
Coating: inogona kushandiswa mukati uye kunze kwemadziro emadziro, latex pendi, nezvimwe.
Zvigadzirwa zveGypsum: senge gypsum board uye gypsum putty.
10. Kuchengetedza kwekushandisa
Paunenge uchishandisa zvekuvaka giredhi cellulose ether, unofanirwa kuterera kune anotevera mapoinzi:
Wedzera maererano nereshiyo yakakurudzirwa, kuwandisa kana kusakwana kuchakanganisa kuita kwekupedzisira.
Iva nechokwadi chekufanana panguva yekusanganiswa kudzivirira kusangana.
Paunenge uchichengeta, teerera kune hunyoro-uchapupu kudzivirira hunyoro uye agglomeration.
Kuvaka giredhi cellulose ether yave chinhu chinowedzera muindasitiri yezvivakwa zvekuvaka nekuda kwezvakasiyana zvivakwa uye kushanda kwakafara. Nekuenderera mberi kwekuvandudzwa kwezvinodiwa zveindasitiri yekuvaka zvekushanda kwezvinhu, tarisiro yekushandisa ye cellulose ether ichave yakakura.
