01.Hydroxyethyl cellulose
Senge isiri-ionic surfactant, hydroxyethyl cellulose haina chete mabasa ekumisa, kukora, kuparadzira, kuyerera, kusungirira, kugadzira firimu, kuchengetedza mvura uye kupa inodzivirira colloid, asiwo ine zvinotevera zvinhu:
1. HEC inonyungudika mumvura inopisa kana inotonhora, uye hairegi pakupisa kwepamusoro kana kuvira, kuitira kuti ive nemhando dzakasiyana-siyana dzekunyungudika uye viscosity maitiro, uye kwete-thermal gelation;
2. Kuenzaniswa neyakazivikanwa methyl cellulose uye hydroxypropyl methyl cellulose, kukwanisa kuparadzira kweHEC ndiyo yakaipisisa, asi iyo inodzivirira colloid ine simba rakasimba.
3. Kukwanisa kwekuchengetedza mvura kwakapetwa kaviri kune iyo yemethyl cellulose, uye ine zviri nani kuyerera kwemutemo.
Chengetedzo kana uchishandisa:
Sezvo iyo yepamusoro-yakagadziriswa hydroxyethyl cellulose ipfu kana cellulose yakasimba, zviri nyore kubata uye kunyungudika mumvura chero bedzi zvinhu zvinotevera zvichionekwa.
1. Pamberi uye mushure mekuwedzera hydroxyethyl cellulose, inofanira kuramba ichikurudzirwa kusvikira mhinduro yacho yakanyatsojeka uye yakajeka.
2. Inofanira kupepetwa muhari yekuvhenganisa zvishoma nezvishoma. Usawedzera zvakananga iyo hydroxyethyl cellulose iyo yakaumbwa kuita mapundu kana mabhora mugomba rekusanganisa muhuwandu hukuru kana zvakananga.
3. Kupisa kwemvura uye pH kukosha kwemvura kune hukama hunokosha nekuparara kwehydroxyethyl cellulose, saka kunyanya kunofanira kubhadharwa kwairi.
4. Usambofa wakaisa zvimwe alkaline zvinhu kumusanganiswa pamberihydroxyethyl cellulosehupfu hunodziirwa nemvura. Kusimudza kukosha kwePH mushure mekudziya kunobatsira pakuparara.
HEC kushandiswa:
1. Inowanzo shandiswa seyakakura mumiriri, inodzivirira, inonamira, stabilizer uye additive yekugadzira emulsion, gel, mafuta, lotion, maziso ekuchenesa, suppository uye piritsi, inoshandiswawo se hydrophilic gel, skeleton zvinhu, kugadzirira skeleton inosimudzira-kusunungurwa gadziriro, uye inogonawo kushandiswa sechikafu.
2. Inoshandiswa senge saizi agent muindasitiri yezvipfeko, bonding, thickening, emulsifying, stabilizing uye zvimwe zvinobatsira mumagetsi uye light industry sectors.
3. Inoshandiswa seyakakora uye sefiltrate inodzikisira yemvura-based drilling fluid uye kupera kwemvura, uye ine zvinooneka kukora mhedzisiro mumvura ine munyu yekuchera mvura. Inogona zvakare kushandiswa senge yemvura kurasikirwa inodzora mumiriri wemafuta tsime simende. Inogona kuchinjika-yakabatana ne polyvalent simbi ions kuita gels.
5. Ichi chigadzirwa chinoshandiswa se dispersant yemvura-based gel fracturing fluids, polystyrene uye polyvinyl chloride mukugadzirwa kwemafuta fracturing. Inogona zvakare kushandiswa se emulsion thickener muindasitiri yependi, humidity sensitive resistor muindasitiri yemagetsi, simende coagulation inhibitor uye mumiriri wekuchengetedza hunyoro muindasitiri yekuvaka. Glazing uye mazino anonamira eiyo ceramic indasitiri. Inoshandiswawo zvakanyanya mukudhinda nekudhaya, machira, kugadzira mapepa, mushonga, hutsanana, chikafu, fodya, mishonga yezvipembenene uye zvinodzima moto.
02.Hydroxypropyl Methyl Cellulose
1. Indasitiri yekuputira: Sezvinoita thickener, dispersant uye stabilizer muindasitiri yekuputira, ine kuenderana kwakanaka mumvura kana organic solvents. sechinobvisa pendi.
2. Ceramic kugadzira: yakashandiswa zvakanyanya sebhainda mukugadzira zvigadzirwa zveceramic.
3. Vamwe: Ichi chigadzirwa chinoshandiswa zvakanyanya muindasitiri yematehwe, mapepa ezvigadzirwa zvemapepa, kuchengetedza michero nemiriwo uye indasitiri yemachira, nezvimwe.
4. Ink kudhinda: semukobvu, dispersant uye stabilizer muindasitiri yeinki, ine kugarisana kwakanaka mumvura kana organic solvents.
5. Plastiki: inoshandiswa senge molding yekuburitsa agent, softener, lubricant, nezvimwe.
6. Polyvinyl chloride: Inoshandiswa seanoparadzira mukugadzirwa kwepolyvinyl chloride, uye ndiyo inonyanya kubatsira mumiriri wekugadzirira kwePVC nekumisa polymerization.
7. Indasitiri yekuvaka: Semugadziri wekuchengetedza mvura uye retarder yesamende dhaka, dhaka rine pumpability. Inoshandiswa sebhainda mukupurasita paste, gypsum, putty poda kana zvimwe zvekuvaka kuvandudza kupararira uye kurebesa nguva yekushanda. Inoshandiswa sepaste ye ceramic tile, marble, kushongedza kwepurasitiki, sekusimudzira paste, uye inogona zvakare kuderedza huwandu hwesimende. Kuchengetwa kwemvura kwehydroxypropyl methylcelluloseHPMCinogona kudzivirira slurry kubva pakutsemuka nekuda kwekuoma nekukurumidza mushure mekushandisa, uye kuwedzera simba mushure mekuoma.
8. Indasitiri yemishonga: kuvhara zvinhu; zvinhu zvemufirimu; chiyero-chinodzora polymer zvinhu zvekugadzirira-kuburitswa gadziriro; stabilizers; suspending agents; tablet binders; tackifiers.
Zvakasikwa:
1. Kuonekwa: chena kana kuti isina-white powder.
2. Hukuru hwechikamu; 100 mesh pass rate yakakura kudarika 98.5%; 80 mesh pass rate i100%. Iyo particle size yeyakakosha yakatarwa ndeye 40 ~ 60 mesh.
3. Carbonization tembiricha: 280-300 ℃
4. Density inooneka: 0.25-0.70g / cm (kazhinji inopoteredza 0.5g / cm), chaiyo giravhiti 1.26-1.31.

6. Kushungurudzika kwepamusoro: 2% mhinduro yemvura ndeye 42-56dyn / cm.
7. Solubility: inonyungudika mumvura uye zvimwe zvinonyungudutsa, zvakadai sechikamu chakakodzera che ethanol / mvura, propanol / mvura, nezvimwewo. Kujeka kwepamusoro uye kushanda kwakagadzikana. Madiro akasiyana ezvigadzirwa ane tembiricha dzakasiyana dzegel, uye solubility inoshanduka ne viscosity. Iyo yakaderera viscosity, iyo yakakura solubility. Madiro akasiyana eHPMC ane akasiyana zvivakwa. Kuparara kweHPMC mumvura hakukanganiswe nepH kukosha.
8. Nekuderera kwemethoxy group content, gel point inowedzera, kunyungudika kwemvura kunoderera, uye basa repamusoro reHPMC rinoderera.
9. HPMCzvakare ine hunhu hwekukora kugona, munyu kuramba, yakaderera ash poda, pH kugadzikana, kuchengetedza mvura, dimensional kugadzikana, yakanakisa firimu-kuumba zvivakwa, uye huwandu hwakawanda hwekupikisa enzyme, dispersibility uye kubatana.
