Yakakwira-viscosity polyanionic cellulose (PAC-HV) yakakosha polima inoshandiswa mune akasiyana maindasitiri maapplication.Ichi chinhu chinogoneka chine mashandisiro mune zvese kubva pakuchera oiri kusvika pakugadzira chikafu.
Polyanionic Cellulose (PAC-HV) Overview
1. Tsanangudzo uye chimiro:
Polyanionic cellulose is water-soluble cellulose derivative ine anionic functional groups.Yayo yakakwirira viscosity musiyano, PAC-HV, inoratidzirwa nepamusoro viscosity kana ichienzaniswa nemamwe marudzi ePAC.Iyo molecular chimiro chePAC-HV inotorwa kubva ku cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro.Kuiswa kweanionic mapoka kunowedzera kunyungudika kwayo mumvura.
2. Zvimiro zvePAC-HV:
Viscosity: Sezvinoratidzwa nezita racho, PAC-HV ine viscosity yakakwirira, ichiita kuti ive yakakodzera kune maapplication anoda kukobvu kana gelling.
Kunyungudika kweMvura: PAC-HV inonyanya kunyungudika mumvura, zvichiita kuti ibudirire mumhando dzakasiyana-siyana dzemvura.
Thermal Kugadzikana: Iyo polymer inoramba yakagadzikana pakupisa kwakanyanya, ichiwedzera kushanda kwayo mumaindasitiri maitiro.
Kushandiswa kwePAC-HV
1. Indasitiri yeOiri neGasi:
Drilling Fluids: PAC-HV inoshandiswa zvakanyanya sechinhu chakakosha mukuchera zvinwiwa kudzora viscosity, yakaturikwa yakaoma uye kuwedzera kugadzikana kwetsime.
Fracturing Fluids: Mu hydraulic fracturing, PAC-HV inobatsira mukudzora viscosity, kuve nechokwadi chekufambisa kwepropant uye kuyerera kwemvura.
2. Indasitiri yezvekudya:
Thickening Agent: PAC-HV inoshandiswa seyakakora muzvigadzirwa zvekudya senge sosi, madhirezi uye madhiri.
Stabilizer: Inowedzera kugadzikana kwe emulsions uye inodzivirira kupatsanurwa kwechikamu mune zvimwe zvekudya.
3. Zvinodhaka:
Kuendeswa Kwezvinodhaka: PAC-HV inoshandiswa sechibhainda uye disintegrant mukugadzirwa kwemishonga kufambisa kuburitswa kwezvinodhaka.
Suspensions: Kumisa kwavo zvivakwa kunoita kuti ive yakakosha mune yemvura mishonga yekugadzira mishonga.
4. Indasitiri yemachira:
Sizing agent: PAC-HV inoshandiswa kugadzira machira kuvandudza simba uye mhando yeshinda panguva yekuruka.
5. Indasitiri yemapepa:
Rubatsiro rwekuchengeta: Mukugadzira mapepa, PAC-HV inoshanda seyamuro yekuchengetedza, inovandudza kuchengetwa kwezvimedu zvakanaka uye mafiritsi.
kugadzira nzira
Kugadzirwa kwePAC-HV kunosanganisira kugadziridzwa kweselulosi kuburikidza nekuita kwemakemikari.
Matanho akajairika anosanganisira:
Alkalizing: Kurapa cellulose nealkali kumisa mapoka ehydroxyl.
Etherification: suma mapoka eanionic kuburikidza ne etherification kuvandudza kunyungudika kwemvura.
Kucheneswa: Chigadzirwa chinobuda chinocheneswa kubvisa tsvina.
kufunga nezvezvakatipoteredza
Nepo PAC-HV ichipa akasiyana mabhenefiti emaindasitiri, kufunga kwezvakatipoteredza kwakakoshawo.
Gadzirisa maitiro ekugadzira kuderedza kukanganisa kwezvakatipoteredza.
Ongorora dzimwe nzira dzine hushamwari kwezvakatipoteredza kana gadziridzo dzezvinobuda muselulosi.
Kurudzirai kudzokorodza uye maitiro ekurasa ane hunyanzvi.
High-viscosity polyanionic cellulose (PAC-HV) ipolymer yakakosha ine huwandu hwakawanda hwekushandisa.Hunhu hwayo hwakasiyana hunoita kuti ive yakakosha mumaindasitiri akadai seoiri uye gasi, chikafu nemishonga.Sezvo tekinoroji iri kuramba ichifambira mberi, kune kuwedzera kutarisisa kune yakagadzikana yekugadzira maitiro uye nharaunda kushandiswa kwePAC-HV mune akasiyana maapplication.
