Cellulose ethers, senge methyl cellulose (MC) uye hydroxypropyl methyl cellulose (HPMC), anoshandiswa zvakanyanya muzvigadzirwa-samende nekuda kwekunaka kwekuchengetedza mvura, kushanda, uye kunamatira zvivakwa. Nekudaro, kuita kweselulosi ether muzvigadzirwa zvesimende kunogona kukanganiswa nezvinhu zvakasiyana, zvinosanganisira mhando uye dosi ye cellulose ether, mhando uye dosi resimende, mamiriro ekurapa, uye mamiriro ekunze. Naizvozvo, zvakakosha kunyatso kudzora mashandiro e cellulose ethers muzvigadzirwa zvesimende kuti ive nechokwadi chekuenderana uye kuita.

1. Kusarudzwa kweCellulose Ether Type uye Dosage

Kusarudzwa kwemhando ye cellulose ether uye dosage yakakosha mukudzora kushanda kwe cellulose ether muzvigadzirwa zvesimende. Yakasiyana cellulose ethers ine zvinhu zvakasiyana, uye sarudzo yemhando yakakodzera ye cellulose ether inoenderana neiyo chaiyo yekushandisa uye kuita zvinodiwa. Semuyenzaniso, HPMC inowanzo shandiswa mumataira anonamira nekuda kwekuchengetedza kwayo mvura zvakanaka uye kunamatira zvivakwa, nepo MC ichiwanzo shandiswa mushanduro nemadhaka nekuda kwekushanda kwayo kwakanaka uye kuchengetedza mvura.

Iyo dosage ye cellulose ether inoitawo basa rakakosha mukudzora kushanda kwayo muzvigadzirwa zvesimende. Kuyerwa kwakakodzera kweselulosi ether kunoenderana nezvinhu zvakasiyana, kusanganisira rudzi uye chiyero chesimende, kushanda kunodiwa uye kuchengetedza mvura, uye mamiriro ekunze. Kazhinji, kuyerwa kwe cellulose ether kunotangira pa 0.1% kusvika 2% nehuremu hwesimende, zvichienderana nekushandiswa chaiko uye zvinodiwa pakuita.

2. Kuenderana neSimenti

Kuenderana kwe cellulose ether ne simenti kwakakosha mukudzora kushanda kwayo muzvigadzirwa zvesimende. Kuwedzerwa kwe cellulose ether kune simenti kunogona kukanganisa nguva yekuisa, simba, uye kushanda kwesementi, zvichienderana nerudzi uye chiyero che cellulose ether uye rudzi rwesimende. Naizvozvo, zvakakosha kuve nechokwadi chekuenderana kwe cellulose ether ne simenti kuti ive nechokwadi chekuenderana uye kuita.

Iko kuenderana kwe cellulose ether ne simenti kunogona kuongororwa nekuita bvunzo dzekuenderana, senge Vicat bvunzo, yekutanga uye yekupedzisira yekumisikidza nguva bvunzo, uye yekumanikidza simba bvunzo. Migumisiro yezviedzo izvi inogona kupa ruzivo rwakakosha pamusoro pekushanda kwe cellulose ether muzvigadzirwa zvesimende uye inogona kushandiswa kugadzirisa rudzi uye chiyero che cellulose ether.

3. Curing Conditions

Mamiriro ekurapa ezvigadzirwa zvesimende anogona kukanganisa zvakanyanya kushanda kwe cellulose ethers. Mamiriro ekurapa, anosanganisira tembiricha, mwando, uye nguva yekurapa, anogona kukanganisa hydration ye simende uye kushanda kwe cellulose ethers. Mamiriro akakwana ekurapa anotsamira pane chaiyo application uye kuita zvinodiwa.

Semuyenzaniso, mumataira anonamira, iwo akanyanya kurapa mamiriro anowanzo ari mukamuri tembiricha ine mwero hunyoro uye nguva yekurapa yemaawa makumi maviri nemana kusvika makumi mana nemasere. Mumareferensi nemadhaka, iwo akanyanya kurapa mamiriro anogona kusiyana zvichienderana neiyo chaiyo mashandisirwo, asi kazhinji anosanganisira yakanyanya tembiricha uye nguva refu yekurapa.

4. Environmental Conditions

Mamiriro ezvakatipoteredza, senge tembiricha, hunyoro, uye kuratidzwa kumakemikari kana zvinosvibisa, zvinogonawo kukanganisa kushanda kweselulosi ether muzvigadzirwa zvesimende. Semuenzaniso, kuratidzwa kune tembiricha yakakwira kana hunyoro hushoma hunogona kukanganisa kuchengetedza kwemvura kweselulosi ethers, zvichikonzera kuderedzwa kwekushanda uye kunamatira. Kuratidzwa kumakemikari kana zvinosvibisa zvinogonawo kukanganisa kushanda kwe cellulose ethers, zvichiita kuti kuderedzwa kwesimba kana kusimba.

Naizvozvo, zvakakosha kuti titarise mamiriro ezvakatipoteredza panguva yekushandiswa uye kushandiswa kweselulosi ether muzvigadzirwa zvesimende. Kuchengetedza kwakakodzera uye kubata kwe cellulose ethers kunogonawo kubatsira kuchengetedza kuita kwavo uye kuve nechokwadi kuenderana kwemhando.

Mukupedzisa, kutonga kunoshanda kwekuita kweselulosi ether muzvigadzirwa zvesimende kunoda kunyatsotariswa kwezvinhu zvakasiyana-siyana, kusanganisira mhando uye dosi ye cellulose ether, kuenderana nesamende, mamiriro ekurapa, uye mamiriro ekunze. Nekugadzirisa zvinhu izvi, zvinokwanisika kuwana hutano hwakafanana uye kushanda kwe cellulose ethers muzvigadzirwa zvesimende, zvichiita kuti kuve nekugadzirisa kushanda, kuchengetedza mvura, uye kunamatira zvinhu.
