Zvigadzirwa zvezvinyorwa, zvakadai sekongiri, dhaka, uye zvimwe zvekuvhara, zvinoshandiswa zvakanyanya muzvivakwa zvazvino. Cellulose etana (akadai seHydroxyPropyl methylcellose (HPMC), HPMC) Kuti uwane izvi zvakanakisa zvivakwa, zvakakosha kuti tinyadzise uye tidzorere kuita kwemheremaloose ana vana.
1. Zvekutanga zvivakwa uye zvinoshanda zve cellulose ana
Cellulose etana inzvimbo yemakemikari eremals of echisikopo cellulose, umo iyo hydroxyl boka rakatsiviwa neboka reEther kuburikidza nekuita kwekuchinja. Mhando dzakasiyana dze cellulose anaiters dzinogona kuve dzakarongedzwa zvichienderana nerudzi uye nhamba yetsiva, uye imwe neimwe mhando ine chikamu chakasiyana muzvigadzirwa zve coment.
Viscosity of cellulose ana maneja:
Iyo viscosity ye cellulose ana ana vana zvakananga inokanganisa rheology uye kugadzikana kweiyo cement paste. Yakakwira-viscosity Cellulose Cellulose Cellulose Consulose Kuchengeta kwemvura uye kusanganisa simba reante, asi inogona kuderedza fluidity yayo. Low-viscosity cellulose ana ana ana ivhu kubatsira kuvandudza kuwedzerwa uye kunhuwa.
Degree rekutsiva
Dhigirii rekutsiva uye kutsiviwa kweiyo cellulose ana ana ana solubility uye iyo viscosity yemhinduro. Dhigirii repamusoro rekutsiva uye yakakwira molar kutsiviwa kazhinji kunogona kuvandudza kuchengetwa kwemvura uye kugadzikana kwemaserulose.
Solubility of cellulose ana maneja:
Iyo yekunyoroveswa kwemvura uye solubility ye cellulose etana inoshandisa iyo kusagadzikana kweiyo coment paste. Cellulose ana ana vana neakanaka solubility inogona kuumba yunifomu yekugadzirisa nekukurumidza, nekudaro ichisimbisa kufanana uye kugadzikana kweiyo paste.
2. Sarudza yakakodzera cellulose ana ana
Mamiriro ekunze akasiyana ekushandisa ane akasiyana mashandiro emabasa ekuita cellulose ana vana. Kusarudza iyo chaiyo mhando uye kutaurwa kwemheremalose ether kunogona kugadzirisa zvakanyanya kuita kwezvinhu zvigadzirwa zve coment:
Binders:
Mukushandisa senge tile anomisheni uye plaster mauto, yakakwirira-viscosity celloulose cell
Zvinhu-Kuchengeta Mvura:
Mukuzvimirira mauto uye simende-yakavakirwa tile inonamira, cell inomesa ana yevana yekuchengetwa kwemvura yakakwirira (senge hemc) inodiwa. Kuchengetwa kwemvura yakakwira kunobatsira kudzivirira kurasikirwa kwemvura nguva dzose, nekudaro kunoziva kukwana kwehydation yekuita uye kwenguva refu yekushandisa.
Kusimbisa Zvinhu:
Cellulose etana inoshandiswa kusimudzira simba rezvishandiso zvigadzirwa zvinoda kuve nekupararira kwakanaka uye zvine mwero kusimudzira kufanana uye kusimba kwematrix.
3. Ongorora nzira yekuwedzera
Kudzora nzira yekuwedzera ye cellulose ether in coment zvigadzirwa zvakakosha kuti uwedzere kushanda kwayo. Izvi zvinotevera zviyero zvinowanzoitika nzira dzekubhadhara:
Maitiro Ekutanga:
Sanganisa cellulose ether nedzimwe yakaoma poda zvinhu zvisati zvaitika. Iyi nzira inogona kudzivirira kuumbwa kweiyo Agglomeration ye cellulose ether mushure mekubata nemvura, nokudaro anovimbisa yunifomu yaro mune slurry.
Inonyorodha nzira yekubatanidza:
Wedzera cellulose ether to coment slurry zvishoma nezvishoma. Iyi nzira yakakodzera mamiriro ezvinhu apo cellulose ether ichipinda nekukurumidza uye inobatsira kuumba kugadzikana kumiswa.
Yakakurirwa yekuwedzera nzira:
Mukuita kwekutanga kugadzirira slumry slurry, kuwedzera cellulose ether mune zvikamu zvinogona kuve nechokwadi chekuparadzira yunifomu yose yekugadzirira uye kuderedza kuunganidzwa.
4. Dzora zvinhu zvekunze
Zvinhu zvekunze zvakadai sekupisa, ph kukosha, uye mwero wekukurudzira ane maitiro akakosha mukuita kwemheremalose ether.
Tembiricha Control:
Iyo solubility uye viscosity ye cellulose ether inoterera zvakanyanya kupisa. Tembiricha yepamusoro inobatsira cellulose ether kuti inyungunuke nekukurumidza, asi inogona zvakare kukonzera iyo visikopa yemhinduro yekuderera. Tembiricha inofanirwa kuchinjirwa zvinoenderana neyakajeka mashandiro ekunyorera kuti uve nechokwadi chekushandiswa kwakakwana uye kuita.
Kugadziriswa pP Kudzora iyo PH Kukosha mukati meiyo yakaringana mhando inogona kusimbisa mashandiro emheremalose ether.
Kukurudzira kuraira: Iyo mwero wekukurudzira anokanganisa mhedzisiro yekupararira kwemherekukwereta ether mumasimendi paste. Yakanyanya kukwira mwero mwero inogona kutungamira kumhepo yekutsanangurwa uye kusunganidzwa kwemherekuru ether, nepo mwero mwero mwero unobatsira kugovera uye kunyungudika cellulose ether.
5. Kuongororwa kesi uye mazano anoshanda
Kuburikidza neyechokwadi kesi kuongorora, tinogona kuenderera nekunyatsonzwisisa chikumbiro uye kurongeka kwehurongwa hwe cellulose ether mune dzakasiyana siment zvigadzirwa:
Yakakwirira-perinoita Tile inonamatira: Kana kambani ichigadzira yakakwirira-perinoita tile inonamatira, yakawanikwa kuchengetwa kwemvura kwechigadzirwa chepakutanga kwaive kusakwana, zvichikonzera kuderera kwekushamwaridzana mushure mekuvaka mushure mekuvaka. Nekusunura yakakwira-mvura-yekuchengetedza hemc uye kugadzirisa iyo yekuwedzera mari uye yekuwedzera nzira (uchishandisa nzira yekutanga), kuchengetwa kwemvura uye kusanganisa kwesimba rezveshuwa zvakabudirira.
Kuzvimiririra pasi pezvinhu: Iyo yekuzvimiririra pasi pezvinhu zvinoshandiswa mune imwe chirongwa yaive neyakaomeswa kumeso uye kushamwaridzana kwepamhepo mushure mekuvakwa. Nekusarudza yakaderera-viscosity HPMC uye optimizing iyo mwero wekukurudzira uye tembiricha kudzora, iyo fluidity uye kuita kwekuvaka kweiyo yakashata inovandudzwa, kugadzira pasi rekupedzisira pasi.
Kudzora kuita kweCellulose ether muzvinyorwa zvigadzirwa ndiyo kiyi yekuvandudza maitiro ekunyatsoita uye maitiro ekuvaka. Nekusarudza rudzi rwerudyi rwe cellulose ether, optimizing nzira yekuwedzera, uye kudzora zvekunakidzwa kwekuwedzera, izvo zvakakosha zvivakwa zveSement, kuderedza, uye fludiity inogona kuvandudzwa zvakanyanya. Mune zvinoshanda zvinoshanda, zvinodikanwa kuti uenderere mberi nekugadzirisa kushandiswa kwemheremelle ether zvichienderana nezvinodiwa chaizvo uye zviitiko zvekushandisa kuti uwane zvakanakisa mibairo.
