Yintoni i-hydroxypropyl methyl seluplose hpmc?

I-HydroxyPOpyl Methyl Selelose HPMC yi-Ionic se-ionic selsulose i-ether exutywe kwi-ethe tenboxymymethmethyl setherbase ityhefu ye-ether ixutywe. I-rabical enye yeoksijini ngenxa ye-hydroxypropyl methyl yesiqulatho kunye nenxalenye eyahlukileyo ye-HydroxyPropy ye-HydroxlyPropy kunye nomxholo ophezulu we-vingsyl kunye nomxholo ophantsi we-thyxyl kunye nomxholo ophezulu we-hydroxypropy Iintlobo, kwaye intsebenzo isondele kwi-hydroxlypropyl methyl selliese. Kodwa kwiintlobo ngeentlobo
 
1, I-HYDROXPOPLL methyl seluplose Solity
I-HydroxyPOpyl Methyl Selelity ye-Soliday ye-Hydroxyl I-Methyl Sellyl seide (i-methyl oxyl selsulose ye-propuloplose) i-methyl i-metsulose inyibilikisi kunye neempawu ezishushu zamanzi. Nangona kunjalo, amaqondo obushushu okuhlaselwa kwe-propyl ye-hydroxy ye-hydroxy iphakame kakhulu kunaleyo ye-methyl iselse emanzini ashushu. Umzekelo, i-viscosity ye-hydroxypropyl methylcelcelgalose yesisombululo esine-2% ye-DEADSXY DS = 0.73 kunye ne-HydroxyPropy I-MS = 0.46 yi-500 MPA kwi-20 pa. Iqondo lokushisa le-gene le-SID lisondele kwi-100 ℃, ngelixa le nto yaseMethyl Seley yeqondo lobushushu limalunga ne-55 ℃. Ngokuphathelele ukubizwa kwayo emanzini, kuphuculwe kakhulu, umzekelo, emva kokutyhoboza i-hydroxypropyl methylcelculose
 
. I-DS = 0.2 ~ 1.0, i-viscofisity ephezulu ye-Hydroxypropyl Methyl Godetion Appelol School kunye neZisombululo ze-Ethanol, kwaye inee-thermoplastic kunye ne-thermoplastic kunye nezomeleza. Ikwanyibilika kwii-hydrocarble ezihlanjelweyo ezinjengeDichloromethane kunye neTrichloromethane, kunye nezinyibilikisi ze-organic ezinjenge-acetone, i-isopropyl utywala. I-solity yayo kwizinyibilikisi ze-organic iphezulu kunomoya wokuluka kwamanzi.
 
I-2, i-hydroxypropyl methyl seluplose villasity yezinto eziphathwayo
I-HYDROXYPPOPLL Methylcelcelcelsulose Izinto zeHydroxylpropyl MethylcelcelceLimose Special Piscomes Uhlobo lwemveliso efanayo, ngokunyuka koxinzelelo kunye nokunyusa, ukugxininiswa okufanayo kweemveliso ezahlukeneyo zeemolekyuli, ubunzima bemoyam yemveliso ingu-viscofity ephezulu. Ulwalamano lwayo ngamaqondo obushushu luyafana ne-methyl seluplose. Xa iqondo lobushushu liyanyuka, i-viscosity iqala ukwala, kodwa xa ifikelela kubushushu obuthile, i-viscosity inyuka ngequbuliso kwaye ukuhlelwa. Iqondo lokushisa lemveliso eline-viscofity eliphantsi liphezulu kunezo zemveliso ezinophawu oluphezulu. Inqanaba lendawo yayo yejeli, ukongeza kwi-viscofity ephezulu kwaye ephantsi ye-ether, kodwa ne-Ether ye-Ethersy kunye ne-Eyerchypropy yeQela eliPhezulu kunye nenqanaba lokufakelwa. Kufuneka kuqatshelwe ukuba i-hydroxypropyl methylcelcelcelose ikwanguPsedoplastic; Isisombululo sayo sizinzile xa sigcinwe kubushushu begumbi kwaye ayibonisi nakuphi na ukonakaliswa kwe-viscosity ngaphandle kokuba kungenxa yokupheliswa kwengqondo.
 
3, I-HydroxyPOpyl Methyl Sellulose Acid kunye neAlkaline Ukuchasana
Hydroxypropyl methylcelcelsele acid ifddroxylypropyl methylcelse acid, i-bitcric acid, i-phocccinic acid, i-phoric acid, njl. Kodwa I-acid ye-acid ye-oction inesiphumo sokunciphisa i-viscofity. I-Alkali efana ne-caustic soda, i-caustic potassium kunye namanzi e-lime ayinampembelelo kuyo, kodwa ifuthe lokukhulisa kancinane kwixesha elizayo.
 
4, i-hydroxypropyl methyl seluplose inokuxutywa
I-Hydroxypropyl methyl isisombululo seselutise sinokudityaniswa kunye ne-polymer ye-polymer ye-willmer, kwaye iba sisisombululo esibonakalayo esibonakalayo nge-viscofity ephezulu. Ezi zinto ziphambili zemolekyuli yi-Plythylene Glycol, Polyvinyl Acetate, Polysilikicone, i-Polymethyl viny ye-Gum Arabic, njl. Njl. I-HydroxyPOpyl Methyl Selelose inokuxutywa kunye ne-Stearic Acid okanye i-Palmic Acid Ester Henceol okanye i-Sorbiol kunye ne-Glycerol, ezi ndawo zinokusetyenziswa njenge-hydroxl yestyl ye-hydyelose ye-hetyl metyl ye-hydyl ye-hydyl ye-hydyelose yeplastiki.
 
I-5, i-hydroxypropyl methyl selliase yamanzi anyibilika
I-HydroxyPOpyl Methyl Sele-Infol-Infor-Infor-Fol-Mersulose I-Ersulose I-Ersulose I-Ether, inokubangela ukunxibelelanisa i-aldehydes, kwaye yenza ukuba i-Ether-artited i-esterited i-odolo, yangaphantsi emanzini. Kwaye wenze i-hydroxypropyl methylcelcellulose istahlose, i-foraldehyde, glyculoldehyde, i-filclehyde isetyenziswe ngokukodwa kwi-Glysoxal njengearhente ye-vlnoxal njengearhente ye-iarment ye-vyoxal njengearhente ye-golyoxal njengearhente yokunxibelelanisa i-gllyoxal njengearhente yokunxibelelanisa i-glynoxal njengearhente yokunxibelelanisa i-glynoxal njengearhente yokunxibelelanisa i-glly-fictorment njenge-iarment-yerimenti yokudibanisa. Umthamo wolu hlobo lwe-arhente enqamlezileyo kwisisombululo kwi-0.2% i-10% ye-Ether Mass, eyona ilungileyo yi-GlyOxal nge-3.3% ye-6% yeyona ifanelekileyo. Iqondo lobushushu ngokubanzi lingu-0 ~ 30 ℃, ixesha yi-1 ~ 120min. Ukunxibelelanisa ukuphendula okugqogqa kudinga ukwenziwa phantsi kweemeko ze-acidic. Ngokubanzi, i-Inorganic eyomeleleyo ye-acid okanye i-orboxyylic acid yongezwa kwisisombululo sokulungelelanisa i-PH yesisombululo malunga ne-2 ~ 6, emva koko i-AldehyDes yongezwa ukuze iphendule. I-Acids isetyenziselwa i-hydrochloric acid, i-phosfuric acid, i-phosphoric acid, i-acetic acid, phakathi kwe-acetic acid okanye i-cuccric acid, ngelixa i-acid acid yeyona ilungileyo. I-Acids kunye ne-Aldehydes zinokongezwa ngaxeshanye ukuvumela isisombululo ukuba sinxibelelane noluhlu lwe-hle. Le mpendulo ihlala isetyenziswa kwinkqubo yokugqibela yenkqubo yokulungiselela i-Selersese I-Eler Sether, ke loo nto i-Selese i-Ether ayizicingeli, kulula ukuyisebenzisa i-20 ~ 25 ~ 25 ~ Xa imveliso isetyenziswa, izinto ze-alkaline zinokongezwa kwisisombululo semveliso ukuze zilungelelanise i-PH yesisombululo ukuba i-alkaline, kwaye imveliso ichithwe ngokukhawuleza kwisisombululo. Le ndlela inokusetyenziswa xa isisombululo se-Itelulose isetyenziselwa ukwenza ifilimu kwaye emva koko ifilimu inyangwa ukuba yenze ifilimu engenanto.
 
6, hydroxypropyl methyl seluplose anti-enzyme
I-Hydroxypropyl Methyl Sellulose Ukunganyangeki kwe-Selelose kwithiyori, kodwa yi-erosion ye-microorgaissussussus, kodwa yintsingiselo ye-enzyme, le yinkcazo yeqela ngalinye kwi-selsulose Isidanga sokufaka endaweni ye-chain ayifani, i-microorganisms inokukhuphela kufutshane namaqela anehlelo ye-glucose ekhutshiweyo ukuba enze iswekile, enokuthandwa ziintsholongwane njengokutya. Ke ngoko, ukuba isidanga sokufakelwa kwe-Elessist seSelulose yonyuka, ukuxhathisa kwe-Teluplose Ether kwi-Erosion ye-Erosion kuya kuphuculwa. Kuxelwe ukuba phantsi kweemeko ezilawulwayo, i-viscofity yentsalela ye-hydroxyl metyl seluplose (DS = 1.9%), i-MTYL ye-ITyyl Selelose (i-MTYL I-TOLINOse (DSYL). I-HydroxyPOpyl Methyl Selelose inamandla amakhulume. Yiyo loo nto i-Hydroxypropyl Methylcelceluplose Menyme Godleme, edityaniswe nokusasazeka kwayo kakuhle, ukwenziwa kwefilimu, isetyenziswa kwi-moulsion coatings, njl., Ngokubanzi akufuneki ukuba bongeze izilondolozi. Nangona kunjalo, ukwenzela ukuthintela ukugcinwa kwexesha elide kwesisombululo okanye ukungcoliseka okunokwenzeka ukusuka kwihlabathi langaphandle, izinto ezigciniweyo zinokongezwa, onyulo lwabo lunokumiselwa ngokweemfuno zokugqibela zesisombululo. I-phenylmercuric acetate kunye ne-manganese fluoilicicial zizinto ezisebenzayo, kodwa zinetyhefu kwaye kufuneka zisebenze ngononophelo. Ngokubanzi, i-5 ~ 5mg phenylmercuric i-acetate ingongezwa kwilitha nganye yesisombululo.
 
7, i-hydroxypropyl methyl seluplose yokusebenza
I-HydroxyPOpyl Methyl Selsulose Ukusebenza kwefilimu ye-hydroxyl melsulose enefilimu egqwesileyo, isisombululo se-actses okanye isisombululo se-orvant, emva komomo, sinefilimu. Inokuthini ukunyangwa okuhle nokunganyangeki kubushushu obuphezulu. Njengathi ukongezwa kweplasitiki ye-hygroscopic, inokuphucula ukuguquguquka kwayo kunye nokuguquguquka, ukuphucula ukutshintsha, i-glycerol kunye ne-sorbil kunye nomnye ofanelekileyo ofanelekileyo. I-windows yesisombululo sesisombululo yi-2% ~ 3%, i-dosage yeplastiki yi-10% ~ yeepesenti ezingama-20% ye-seluplose. Ukuba umxholo weplastiki uphantsi, i-shrinkad panomen ye-colloid yokuphelelwa ngumzimba inokwenzeka kumswakama ophezulu. Amandla e-sunsen yefilimu yongezwe iplastiki inkulu kakhulu kunokuba akongezi, kwaye enyuka ngokunyuka kwesixa semali eyongeziweyo, ngenxa yefilimu yefilimu ikwanda ngokunyuka kweplastiki.
