Cellulose yekuvaka ndeyekuwedzera inonyanya kushandiswa mukugadzira kuvaka. Cellulose yekuvaka inonyanya kushandiswa muvhu rakaoma dhaka. Kuwedzerwa kwe cellulose ether kwakaderera zvikuru, asi kunogona kuvandudza zvakanyanya kushanda kwevhu rakanyorova uye kukanganisa kuvakwa kwedhaka. Kuita kunofanirwa kutariswa pakushandiswa. Saka ndezvipi zvemuviri zve cellulose zvekuvaka, uye ndeipi nzira yekuvaka ye cellulose yekuvaka? Kana iwe usingazive zvakawanda nezve zvivakwa uye maitiro ekuvaka e cellulose yekuvaka, ngatitarisei pamwe chete.
Ndezvipi zvinhu zvemuviri zve cellulose zvekuvaka:
1. Kuonekwa: chena kana kuti isina-white powder.
2. Hukuru hwechikamu; chiyero chekupasa kwe100 mesh yakakura kupfuura 98.5%; chiyero chekupasa che80 mesh yakakura kupfuura 100%.
3. Carbonization tembiricha: 280-300°C
4. Inooneka density: 0.25-0.70 / cm3 (kazhinji inopoteredza 0.5g / cm3), chaiyo giravhiti 1.26-1.31.
5. Discoloration tembiricha: 190-200°C
6. Kushungurudzika kwepamusoro: 2% mhinduro yemvura ndeye 42-56dyn / cm.
7. Inonyungudika mumvura uye zvimwe zvinonyungudutsa, zvakadai sechikamu chakakodzera che ethanol / mvura, propanol / mvura, trichloroethane, nezvimwewo. Kujeka kwepamusoro, kuita kwakagadzikana, zvakasiyana-siyana zvezvigadzirwa zvine tembiricha yegel dzakasiyana, solubility shanduko ine viscosity, iyo yakadzikira viscosity, iyo yakanyanya kunyungudika, zvakasiyana-siyana zveHPMC zvine mimwe misiyano mukuita, uye kunyungudika kweHPMC mumvura hakukanganiswe. ne pH kukosha.
8. Nekuderedzwa kwemethoxyl content, gel point inowedzera, mvura yakanyunguduka yeHPMC inoderera, uye basa repamusoro rinodererawo.
9. HPMC inewo maitiro ekukora simba, munyu kuramba, yakaderera ash poda, PH kugadzikana, kuchengetwa kwemvura, dimensional kugadzikana, yakanakisa firimu-kuumba pfuma, uye yakawanda enzyme kuramba, dispersibility uye cohesiveness.
Ndeipi nzira yekuvaka ye cellulose yekuvaka:
1. Base-level zvinodiwa: Kana kusungirirwa kwechigadziko-level madziro hakugone kuzadzisa zvinodiwa, iyo yekunze yekumusoro-yepamusoro madziro inofanira kunyatsocheneswa, uye iyo interface agent inofanirwa kushandiswa kuwedzera simba rekuchengetedza mvura madziro uye nokudaro kuwedzera kusimba kwekubatana pakati pemadziro uye polystyrene board.
2. Tamba mutsara wekutonga: pop up yakatwasuka uye yakatwasuka mitsara yekudzora yemagonhi ekunze nemahwindo, majoini ekuwedzera, majoini ekushongedza, nezvimwe pamadziro.
3. Turika tambo yereferensi: Turika vertical referensi waya dzesimbi pamakona mahombe (makona ekunze, makona emukati) ekunze kwechivako madziro uye dzimwe nzvimbo dzinodiwa, uye anorembera mitsetse yakachinjika panzvimbo dzakakodzera pauriri hwega hwega kudzora kuchinjika nekudzika kwechivako. iyo polystyrene board.
4. Kugadzirira kwepolymer adhesive mortar: Nyaya iyi yakagadzirwa nepolymer adhesive mortar, iyo inofanira kushandiswa maererano nezvinodiwa zvechigadzirwa ichi, pasina kuwedzera chero zvimwe zvinhu, zvakadai semende, jecha uye mamwe mapolymers.
5. Namatira jira regidhi rakapidiguka: Nzvimbo dzese dzakavhurika padivi repasted polystyrene board (senge majoini ekuwedzera, majoini ekugadzirisa chivako, majoini etembiricha uye mamwe sutures pamativi ese, magonhi nemahwindo) anofanira kurapwa nejira regridhi. .
6. Adhesive polystyrene board: Cherechedza kuti kuchekwa kwacho kune perpendicular kune bhodhi pamusoro. Kutsauka kwehukuru kunofanira kusangana nezvinodiwa nemirairo, uye majoini ebhodhi re polystyrene haafaniri kusara pamakona mana emukova nehwindo.
7. Kugadziriswa kwezvitsigiro: nhamba yezvitsigiro inopfuura 2 pamamita emamita (yakawedzera kusvika kune 4 kune zvivako zvepamusoro).
8. Gadzirira dhaka rekupurasita: Gadzirira dhaka rekupurasita zvinoenderana nereshiyo yakapihwa nemugadziri, kuitira kuti uwane kuyerwa kwakaringana, mechanical yechipiri inomutsa, uye kunyange kusanganisa.
Pakati pemhando dze cellulose inoshandiswa pakuvaka, iyo cellulose ether inoshandiswa nehydroxypropyl methylcellulose mune yakaoma poda mortar inonyanya hydroxypropyl methylcellulose ether. Hydroxypropyl methylcellulose inonyanya kuita basa rekuchengetedza mvura, kukora uye kuvandudza mashandiro ekuvaka mune yakaoma poda dhaka.
