Basa re cellulose ether mudura

Cellulose etherkuchengetwa kwemvura

Kuchengetwa kwemvura kwedhaka kunoreva kugona kwedhaka kubata nekukiya mvura. Kana dhaka re cellulose ether rakawanda, kuchengetedza mvura kuri nani. Nekuti chimiro che cellulose chine hydroxyl ne ether bond, hydroxyl ne ether bond boka remaatomu eokisijeni nemamorekuru emvura kugadzira hydrogen bond, kuitira kuti mvura ipinde mumvura inosunga, ichitenderedza mvura, kuitira kuti iite basa rekuchengetedza mvura.

Kunyungudika kwe cellulose ether

1. Ether ine cellulose yakawanda iri nyore kupararira mumvura isina kuungana, asi mwero wekunyungudika kwayo unononoka zvikuru. Ether ine cellulose iri pasi pemamesh makumi matanhatu inonyungudika mumvura kwemaminitsi angangoita makumi matanhatu.

2. Zvidimbu zvitete zve cellulose ether mumvura zviri nyore kuparadzira uye hazviunganidzike, uye mwero wekunyungudika uri pakati nepakati. Cellulose ether inodarika 80 mesh inonyungudutswa mumvura kwemaminitsi angangoita matatu.

3. Ultrafine cellulose ether inopararira nekukurumidza mumvura, inonyunguduka nekukurumidza uye inoita viscosity inokurumidza. Cellulose ether iri pamusoro pe120 mesh inonyunguduka mumvura kwemasekondi angangoita 10-30.

Kana zvikamu zve ether zve cellulose zvakapfava, zvinoita kuti mvura irambe ichichengetwa zvakanaka, zvikamu zve cellulose ether uye pamusoro pemvura zvinonyungudika pakarepo zvoita gel phenomenon. Guruu rinoputira zvinhu izvi kudzivirira mamorekuru emvura kuti asarambe achipinda. Dzimwe nguva, kunyangwe ikakurungwa kwenguva yakareba, mhinduro yacho haigone kupararira zvakaenzana uye kunyungudika, zvichiita dhaka rakaita flocculent solution kana agglomerate. Zvikamu zvitete zvinopararira uye zvinonyungudika pakarepo kana zvasangana nemvura kuti zvigadzire viscosity yakafanana.

PH kukosha kwe cellulose ether (kunonoka kuonda kana simba rekutanga)

Kukosha kwePH kwevagadziri ve cellulose ether kumba nekune dzimwe nyika kunodzorwa zvakanyanya pa7, iyo ine acidic. Nekuti kuchine akawanda magadzirirwo e glucose ring yakaora mumvura muchimiro che molecular ye cellulose ether, glucometer yakaora mvura ndiyo boka guru rinokonzera kunonoka kwesimende. Mhete yeglucose yakaora mvura inogona kugadzira calcium ions mu solution ye hydration yesimende kubva mu calcium molecular compounds, kuderedza huwandu hwe calcium ion mu cement hydration nguva ye induction, kudzivirira kuumbwa uye kunaya kwe calcium hydroxide uye calcium salt crystals, nokudaro zvichinonotsa maitiro e hydration yesimende. Kana PH ikava alkaline state, mortar ichaonekwa pakutanga kwesimba. Iye zvino mafekitori mazhinji ekugadzirisa PH value achishandisa sodium carbonate, sodium carbonate imhando yekukurumidzira, sodium carbonate inogona kuvandudza mashandiro esimende particle surface, zvichiita kuti kubatana pakati pezvikamu kuwedzere, kuwedzera kuvandudza viscosity ye slurry, mortar uye sodium carbonate uye calcium ion compound nekukurumidza, zvakakonzera kuumbwa kwe ettringite, simende condensation nekukurumidza. Naizvozvo, kukosha kwePH kunofanirwa kugadziriswa zvichienderana nevatengi vakasiyana mukugadzirwa chaiko.

Cellulose ether gasi induction

Mhepo inopinza cellulose ether inokonzerwa nekuti cellulose ether inongovawo surfactant, basa rekubatanidza cellulose ether rinonyanya kuitika mu gas-liquid-solid interface, yekutanga ndiyo kuiswa kwemabubbles, ichiteverwa nekupararira uye kunyorovesa. Cellulose ether ine alkyl group, inoderedza zvakanyanya kushushikana kwemvura uye simba remvura, mhinduro yemvura panguva yekumutswa iri nyore kugadzira mabubbles madiki akawanda akavharwa.

Kuunganidzwa kwe ether ye cellulose

Cellulose ether inonyungudutswa mumortar nekuda kwecheni yayo yemamorekuru yeboka remethoxy nehydroxypropyl muslurry ine calcium ions uye aruminiyamu ions mukugadzirwa kwegel ine viscous uye yakazadzwa nemota yesimbi isina simende, inovandudza huwandu hwemortar, inoita basa rekuzadza nekusimbisa. Zvisinei, kana matrix yecomposite ikadzvanywa, polymer haigone kutamba rutsigiro rwakasimba, saka simba nekumanikidzwa kwemortar kunoderera.

Kuumbwa kwemafirimuether ye cellulose

Firimu rakatetepa relatex rinoumbwa pakati pe cellulose ether ne simende mushure mekunyoroveswa. Firimu iri rine simba rekuvharisa uye rinovandudza kuoma kwesimbi pamusoro pesimbi. Nekuti cellulose ether ine mvura yakanaka, chengetedza mamorekuru emvura akakwana mukati mesimbi, nokudaro zvichiita kuti simende irambe yakasimba uye ichioma uye ikure zvakakwana, wedzera simba rekubatanidza simende, panguva imwe chete wedzera kunamira kwesimbi ye simende, simende ine plasticity yakanaka uye kusimba, kuderedza kusimba kwesimbi.
