1. Iimpawu ezahlukeneyo
I-Hydroxypropyl methylcellulose: i-fibrous emhlophe okanye emhlophe okanye i-granular powder, ephuma kwiindidi ze-cellulose ezixutywe nge-ethers ezingezo-ionic.Yi-semi-synthetic, engasebenzi, i-viscoelastic polymer.
I-Hydroxyethyl cellulose: (HEC) yi-cellulose emhlophe okanye ekhanyayo, engenavumba, i-non-toxic fibrous okanye i-powdered solid, elungiswe yi-etherification ye-alkaline cellulose kunye ne-ethylene oxide (okanye i-chloroethanol).yeye-non-ionic soluble cellulose ethers.
2. Ukusetyenziswa okwahlukeneyo
I-Hydroxypropyl methylcellulose: Isetyenziswe njenge-thickener, dispersant kunye ne-stabilizer kwi-industry ye-coating, kwaye inokuhambelana kakuhle emanzini okanye kwi-solvents eziphilayo.Njengesixhobo sokususa ipeyinti;njenge-dispersant kwimveliso ye-polyvinyl chloride, iyona arhente yokuncedisa ekulungiseleleni i-PVC ngokumiswa kwe-polymerization;ikwasetyenziswa kakhulu kwisikhumba, iimveliso zephepha, ukugcinwa kweziqhamo nemifuno kunye nemizi-mveliso yelaphu.
I-Hydroxyethyl cellulose: isetyenziswe njenge-adhesive, i-surfactant, i-agent ekhuselayo ye-colloidal, i-dispersant, i-emulsifier kunye ne-dispersion stabilizer, njl. Inoluhlu olubanzi lwezicelo kwiingubo, ii-inki, iifayili, ukudaya, ukwenza iphepha, izimonyo, i-pesticides, i-mineral processing, i-oil extraction. kunye namayeza.
3. Ukunyibilika okwahlukileyo
I-Hydroxypropyl methylcellulose: Iphantse ingabikho kwi-ethanol epheleleyo, i-ether, kunye ne-acetone;iyadumba ibe yicolloidal ecacileyo okanye encinci ye-turbid kumanzi abandayo.
I-Hydroxyethyl cellulose: ineempawu zokujiya, ukuxhoma, ukubopha, ukumilisela, ukusasaza, kunye nokugcina ukufuma.Izisombululo ezinoluhlu oluhlukeneyo lwe-viscosity zinokulungiswa.Inonyibiliko oluhle kakhulu lwetyuwa kwi-electrolytes.
IHydroxypropyl methylcellulose (HPMC) Iimpawu zomzimba nezekhemikhali:
1. Ukubonakala: I-MC imhlophe okanye iphantse imhlophe i-fibrous okanye i-granular powder, ayinavumba.
2. Iipropati: I-MC iphantse inganyibiliki kwi-ethanol epheleleyo, i-ether kunye ne-acetone.Isasaza kwaye idumba ngokukhawuleza emanzini ashushu kwi-80 ~ 90 ℃, kwaye inyibilika ngokukhawuleza emva kokupholisa.Isisombululo se-aqueous sizinzile kwiqondo lokushisa lokushisa kwaye siyakwazi i-gel kwiqondo lokushisa eliphezulu, kwaye i-gel inokutshintsha kunye nesisombululo kunye nobushushu.Inobumanzi obugqwesileyo, i-dispersibility, i-adhesion, i-thickening, i-emulsification, ukugcinwa kwamanzi kunye neempawu zokwenza ifilimu, kunye nokungangeni kwigrisi.Ifilimu eyenziweyo inokuqina okubalaseleyo, ukuguquguquka kunye nokungafihli.Ngenxa yokuba i-non-ionic, inokuhambelana nezinye i-emulsifiers, kodwa kulula ukuyikhupha ityuwa kwaye isisombululo sizinzile kuluhlu lwe-PH2-12.
3. Ubuninzi obubonakalayo: 0.30-0.70g / cm3, ubuninzi malunga ne-1.3g / cm3.
2. Indlela yokuphelisa:
Imveliso ye-MC yongezwa ngokuthe ngqo emanzini, iya kuxutywa kwaye emva koko inyibilike, kodwa oku kuchithwa kucotha kakhulu kwaye kunzima.Kucetyiswa ukuba kusetyenziswe iindlela ezintathu zokuchitha, kwaye umsebenzisi unokukhetha eyona ndlela ifanelekileyo ngokwemeko yokusetyenziswa:
1. Indlela yamanzi ashushu: Ekubeni i-MC inganyibiliki emanzini ashushu, i-MC inokusasazwa ngokulinganayo emanzini atshisayo kwinqanaba lokuqala.Xa sele ipholile, iindlela ezimbini eziqhelekileyo zichazwa ngolu hlobo lulandelayo:
1).Beka umlinganiselo ofunekayo wamanzi ashushu kwisikhongozeli kwaye ufudumale ukuya kuma-70°C.Yongeza kancinci kancinci i-MC phantsi kokuphazamiseka kancinci, qalisa ukudada phezu kwamanzi, kwaye ngokuthe ngcembe wenze i-slurry, kwaye upholise uludaka phantsi kokuphazamiseka.
2).Yongeza i-1/3 okanye i-2/3 yomthamo ofunekayo wamanzi kwisikhongozeli kwaye uyifudumeze ukuya kuma-70℃.Landela indlela ye-1) ukusabalalisa i-MC ukulungiselela udaka lwamanzi ashushu;uze ungeze inani eliseleyo lamanzi abandayo okanye amanzi e-ice Kwi-slurry yamanzi ashushu, pholisa umxube emva kokuvuselela.
2. Indlela yokuxuba umgubo: Hlanganisa i-MC powder particles kunye nenani elilinganayo okanye elikhulu lezinye izithako ze-powdery ukuze uzisasaze ngokupheleleyo ngokuxuba okomileyo, uze udibanise amanzi ukuze uchithe, ngoko i-MC inokuchithwa ngaphandle kwe-agglomerating.
3. Indlela yokumanzisa i-solvent ye-Organic: i-pre-disperse okanye i-moisten MC kunye ne-solvent ye-organic, njenge-ethanol, i-ethylene glycol okanye i-oyile, uze udibanise amanzi ukuze udibanise, ngoko i-MC ingachithwa kakuhle ngeli xesha.
3. Injongo:
Le mveliso isetyenziswa ngokubanzi kulwakhiwo lwezakhiwo, izinto zokwakha, iingubo zokwaleka, iipasta zephepha lodonga, izongezo zepolymerization, izisusi zepeyinti, isikhumba, i-inki, iphepha, njl.nj Umzekelo, isetyenziswa njenge-binder, i-thickener kunye ne-arhente yokugcina amanzi kwizinto zokwakha, njenge-agent-forming agent kunye ne-thickener kushishino lokugquma, kwaye isetyenziswa ngokubanzi kwimimandla efana ne-petroleum drilling kunye neshishini lemihla ngemihla lemichiza. .
Iimpawu zomzimba kunye neekhemikhali ze-methyl cellulose (MC):
3. Ukubonakala: I-MC imhlophe okanye iphantse imhlophe i-fibrous okanye i-granular powder, ayinavumba.
Iipropati: I-MC iphantse yanganyibiliki kwi-ethanol epheleleyo, i-ether kunye ne-acetone.Isasaza kwaye idumba ngokukhawuleza emanzini ashushu angama-80 ~ 90> ℃, kwaye inyibilika ngokukhawuleza emva kokupholisa.Isisombululo se-aqueous sizinzile kwiqondo lokushisa eliqhelekileyo kwaye siyakwazi i-gel kwiqondo lokushisa eliphezulu, kwaye i-gel inokutshintsha kunye nesisombululo kunye nobushushu.Inobumanzi obugqwesileyo, i-dispersibility, i-adhesion, i-thickening, i-emulsification, ukugcinwa kwamanzi kunye neempawu zokwenza ifilimu, kunye nokungangeni kwigrisi.Ifilimu eyenziweyo inokuqina okubalaseleyo, ukuguquguquka kunye nokungafihli.Ngenxa yokuba i-non-ionic, inokuhambelana nezinye i-emulsifiers, kodwa kulula ukuyikhupha ityuwa kwaye isisombululo sizinzile kuluhlu lwe-PH2-12.
1.Ubuninzi obubonakalayo: 0.30-0.70g / cm3, ubuninzi malunga ne-1.3g / cm3.
Okokuqala.Indlela yokuphelisa:
