Marara eKatsi eMontmorillonite ePremium Akasimba, Anonyudzwa Nekukurumidza, Guruva Rishoma, Rinogara Nenguva Refu, Kubvisa Madoro, Kubvisa Madoro Zviri Nyore, Zvakachengeteka Kumakati Ese

1. Zvicherwa zvechisikigo, zvicherwa zvechisikigo zvisina chepfu uye zvisina chepfu, kusashanda zvakanaka mumuviri, kusatsamwisa, kusasara, uye kusanyudzwa nemuviri, zvinogona kushandiswa nezvipfuyo, vacheche, nevana vadiki.

2. Simba rakasimba kwazvo rekunyudza hwema, chimiro chechikamu chekutanga chekunyudza hwema chinounza nzvimbo yakakura kwazvo, iyo inogona kunyudza hwema, hunyoro, mabhakitiriya, uye zvinhu zvinodhaka, uye inovhara hwema nekukurumidza painobatwa.

3. Inoungana nekukurumidza kana yasangana nemvura, hazvisi nyore kuiparadzira. Mushure mekunwa mvura, inokurumidza kukura uye kuoma, uye agglomerate yacho inenge yakamanikana uye hainamati pasi. Zviri nyore kuchenesa uye haishandisike zvakanyanya.

4. Guruva shoma, harinyanyi kushungurudza mhino nekufema, rine magadzirirwo akanaka, harina guruva, harina guruva, rinobatsira vanhu vane tsiye nyoro.

5. Kugadzikana kwakasimba, hakukurumidzi kuora, hakukurumidzi kunaya, hakukurumidzi kupisa, hakukurumidzi kuumbwa, kunochengetwa kwenguva yakareba, kushanda kwakasimba.

1, Nzvimbo yekutsinhana kweCation

Kuchinjana kweCation chimwe chezvinhu zvakakosha zvemontmorillonite. Macations ari pakati pe montmorillonite layers ane mukana wekuchinjana, uye huwandu hwese hwemacations aya hunonzi cation exchange capacity (CEC). Mumvura, mamwe macations anochinjana uye mamorekuru emvura anogona kupinda mu interlayer, uye maitiro aya anogona kudzoserwa. Nekushandisa maitiro ekuchinjana kwecation emontmorillonite, zvigadzirwa zvakasiyana-siyana zvakaita se sodium based bentonite, lithium based montmorillonite, activated clay, pillared montmorillonite, uye organic montmorillonite zvinogona kugadzirwa.

2. Hunhu hwekunwa mvura uye kuzvimba

Montmorillonite ine huwandu hwakawanda hwema hydroxyl groups muchimiro chayo, ine hydrophilicity yakasimba uye hunhu hwakakosha hwekunwa mvura uye kuzvimba. Kuwedzera kunonyanya kuenderana nekunyoroveswa kwe interlayer cations, iyo inonyudza mamorekuru emvura kuti igadzire hydration film, ichiwedzera nzvimbo ye interlayer uye ichikonzera kuwedzera. Mushure mekunyudza mvura, huwandu hunogona kuwedzera kakawanda kusvika kakawanda kuti hugadzire zvinhu zvakaita segel. Kuwedzera kwe hydration kwe montmorillonite kunosanganisira matanho matatu:

① Mvura pamusoro

② Kunyoroveswa kwemvura muIonic

③ Kunyoroveswa kwemvura mumuviri

3, Kumiswa kwakapararira

Mumvura ine simba, nekuda kwesimba risingashande re montmorillonite particles, dzinodzingana uye zvinonetsa kugadzira ma particle aggregates makuru pahuwandu hwakaderera. Nokudaro, dzine hunhu hwakanaka hwekumisikidza uye dzinogona kushandiswa se suspension agents. Kazhinji, hunhu hwekumisikidza hunowedzera ne pH value, uye huri nani mumamiriro e alkaline pane mumamiriro e neutral uye acidic.

4, pfuma inokora

Kana ikasanganiswa nemvura, montmorillonite inonyorovesa uye inokura, zvichiita kuti pave nechimiro chikuru che network chine mativi matatu. Mamorekuru emvura nezvidimbu zve lotion zvinoputirwa uye zvinoparadzaniswa kuti zviwedzere kuramba kufamba kwazvo, kuitira kuti zviwane simba rekukora. Nekufamba kwenguva, chimiro ichi che colloidal chinowanzo gadzikana.

5. Thixotropy

Panguva yekukurunga, chimiro checolloidal chinokanganiswa, viscosity yesystem inoderera, uye inova sol; Kana yakamira, chimiro checolloidal chinodzoka, uye viscosity yesystem inowedzera muchimiro chegel. Maitiro ekudzoreredza chimiro checolloidal anodzoreka uye anozivikanwa sethixotropy yemontmorillonite.

6, Kugadzikana

Montmorillonite imineral yechisikigo isina organic ine kugadzikana kwakanaka uye inodzivirira mamiriro ekunze.

① Kugadzikana kwakanaka kwemakemikari

Montmorillonite hainyungudike mumvura uye mune zvakasiyana-siyana zvinonyungudutsa, uye haideredzwe kana kuoxidized patembiricha yemumba. Ine pH resistance yakakura uye chimiro chayo hachikanganisike nyore nemaacid, mabhesi, munyu, nezvimwewo. Inoenderana zvakanaka neorganic anions, alcohol solvents, nezvimwewo.

② Kugadzikana kwakanaka kwekupisa

Tembiricha ye dehydroxylation chikero chekuongorora kuramba kupisa kwe montmorillonite, zvichiratidza kugadzikana kwayo pakupisa. Tembiricha ye dehydroxylation ye montmorillonite inowanzova 550 ℃ -750 ℃, apo mapoka e structural hydroxyl anobviswa asi chimiro che layer hachiparadzwe, zvichiratidza kugadzikana kwakanaka pakupisa.

③ Kugadzikana kwakanaka kwezvemuviri

Montmorillonite haikanganisike nemabhakitiriya, tupukanana, nezvimwewo. Kunyungudika kwayo hakukurumidzi kuumbwa kana kuora kana kunyorova kana kuchipisa, kunyanya munzvimbo dzine hunyoro kana tembiricha yepamusoro ye30-40 ℃ muzhizha. Haipindi mu enzyme hydrolysis, kunhuwa, kana kuderedza viscosity se organic thickeners dzakadai se cellulose ne xanthan gum, uye ine hunhu hwakanaka hwekudzivirira ngura uye kudzivirira kuora.

Kuchengetedzeka kwemushonga: Semushonga wekudzivirira manyoka usingatengeswi nechiremba, hauwanzotorwa nemuviri wemunhu uye hauna njodzi. Zvisinei, zvinofanira kucherechedzwa kuti:

① Inofanira kutorwa kwemaawa 1-2 zvakasiyana nemimwe mishonga kuti isakanganise kupinza kwayo.

② Kunwa mushonga wakawandisa kunogona kukonzera kuvimbiwa.

③ Pakurapa manyoka akanyanya, zvakakosha kutarisisa kutsiva mvura inobuda mumuviri kudzivirira kupera mvura mumuviri.

Musiyano uripo pakati pemhando yeindasitiri neyemishonga: Montmorillonite ine mashandisirwo akasiyana ine mwero wekuchena nekusachena kwakasiyana, uye haigone kusanganiswa. Semuenzaniso, bentonite yeindasitiri haifanirwe kudyiwa mukati.
