I-HydroxyPOpyl Methylcelcelcelose luhlobo lwe-unic se-ionic sether exutywe. Ngokungafaniyo ne-Ionic Methyl Carboxymethyl Setelose Telupe Ter, ayiphenduli ngeentsimbi ezinzima. Ngenxa yomyinge ohlukileyo we-APENSGSYL kwi-hydroxypropyl methyl sellyulose. Nangona kunjalo, kwiindidi nganye, nangona kuphela iQela elincinci le-hydroxypropy okanye inani elincinci le-APENCYL Gqatywayo, kukho umahluko omkhulu kwi-solity yezinyibilikisi ezihlangeneyo.
(1) Ipropathi yokuluka ye-hydroxypropyl methylcelcelceluplose
Isifo se-hydroxypropyl methylcelcelcelsulose emanzini e-Hydroxly Ge sethylcelied i-propylcelose i-propylcelose iguqulwe yi-propylcelies ye-propylcelose ineempawu ezifanayo zokuluka kwamanzi kunye ne-idolloulity eshushu. Nangona kunjalo, ngenxa yeqela eliguqulweyo ye-hydroxypropy, ubushushu bayo bokuhlutha kumanzi ashushu bungaphezulu kakhulu kune-methyl seluplose. Umzekelo, i-viscosity ye-hydroxypropyl methylcelcelcelse isisombululo esiyi-2% ye-DEATGY STINGY DS = 0.46 ngo-5 ° C, i-MPAFL ye-MPILLYPOse kwi-55 ° C. Ngokuphathelele ukubenzela amanzi, kuye kwaphuculwa kakhulu. Umzekelo, i-rover-idropypropyl methylcelcelgalose (i-Granular I-0.2 \ 0 ° C kunye ne-20% ye-ASCIOR TIDISIT ye-2% ye-ACTEARS inokuthengwa kwiqondo lobushushu begumbi, linyibilika ngokulula emanzini ngaphandle kokupholisa.
Ulwimi lwe-Hydroxypropyl Methylcelcelcelsulose kwi-Sporganisent kwi-SolubayPropyl Methylcelgalose kwi-Sols Shotsents ilunge ngakumbi kune-methylcelculose. Ukufumana iimveliso ezingasentla kwe-2.1, i-viscofisity ye-Hydroxypropyl Methylcelcelsulose equkethe i-hydroxlypropyl Nks = 0.2 ~ I-SEPSECY SOPRORY STOORS, NE-ETHANoL iphakathi kunye ne-thermoplastic kunye ne-thermoplastic. Ikwanyibilika kwi-hydrocarble ecekeceke njenge-methylene chloride kunye ne-chloroform, kunye nezinyibilikisi ze-organic ezinje nge-acetone, i-Iyopropanol yotywala. I-solity yayo kwizinyibilikisi ze-organic ilunge ngakumbi kunomoya wokungasebenzi kwamanzi.
. Uhlobo lwemveliso olufanayo luyanyuka ngokunyuka koxinzelelo. Ngeemveliso ezinamatye ahlukeneyo eemolekyuli kugxininiso olufanayo, imveliso enesisindo esikhulu semolekyuli inophawu oluphezulu. Ulwalamano lwayo ngamaqondo obushushu luyafana ne-methyl seluplose. Xa iqondo lobushushu liphuma, i-viscosity iqala ukuncipha, kodwa xa ifikelela kubushushu obuthile, i-viscosity inyuka ngequbuliso kwaye ukuhlelwa. Iqondo lokushisa le-gel lemveliso ye-viscofity ephezulu. iphakamile. Inqaku layo lejeli alihambelani kuphela kwi-ethertosity ye-ether, kodwa ikwanxulumene nokudityaniswa komyinge weqela le-Accovesxyl kunye neqela le-hydroxypropy kwi-ether kunye nesayizi yenqanaba elipheleleyo le-Ether. Kufuneka kuqatshelwe ukuba i-hydroxypropyl methylcelcelistic ikwanguPseudopristic, kwaye isisombululo sayo sizinzile kubushushu begumbi ngaphandle kokuthathwa kwe-vismmatity ngaphandle kokuba kunokwenzeka ukuba kubekho ukonakaliswa kwe-enzymatic.
. Iityiwa ngokubanzi ezinje nge-hloride, bromide, i-phosphate, i-nitrate, njl. Njl. Nangona kunjalo, ukongezwa kwetyuwa kunefuthe elithile kwiqondo lokushisa lesisombululo se-acera. Xa ukugxininiswa kwetyuwa kuyanda, iqondo lobushushu liyancipha. Xa uXeko seTyuwa kuPhepha inqaku leSoftwation, i-viscosity yesisombululo idla ngokunyuka. Ke ngoko, yongezwa inani elithile letyiwa. , kwisicelo, inokufezekisa ifuthe lokufundisa ngakumbi kwezoqoqosho. Ke ngoko, kwezinye iinkqubo, kungcono ukusebenzisa umxube we-selsulose ether kunye netyuwa kunesisombululo esiphezulu sokufezekisa isiphumo sokuqaqamba.
. Inokumelana nenani elithile lee-acids ezikhanyayo, ezinje nge-fortic acid, i-acetic acid, i-ficcric acid, i-acid ye-phoric acid inesiphumo sokunciphisa i-vickosity. I-Alkalis efana ne-caustic soda, i-caustic potash kunye namanzi e-lime ayinampembelelo kuyo, kodwa banokongeza nje ukubonwa kwesisombululo, emva koko bancipha.
. Ezi pollements ezidityanisiweyo zibandakanya i-Polythylene Glycol, Polyvinyl acetate, Polyvinyacone, Polymethylvinylviny I-gurity yemolekyuli yendalo efana ne-gum Arabic, i-bean gum gum, iKaraya Gum, njl njl. I-HydroxyPOpyl Methylcelcelgalose ikwanokudityaniswa ne-Mannitol Ester okanye i-Sortibil Ester ye-Steric Acid okanye i-Palric Acid, kwaye inokuthi isetyenziswe njenge-hydroxlyproplose ye-cutyulose.
. I-AldehyDes eyenza i-HydroxyPyl Methylcelcelgalose i-Infolneule, i-Glycinic Aldehyde, i-Goccinic Aldehyde, i-Goccinic kufuneka isetyenziswe njenge-arhente enqamlezileyo kwimveliso imveliso. Inani lolu hlobo lwe-arhente yokunxibelelanisa i-contrey kwisisombululo yi-0.2% ye-10% ye-Ether ye-ether, ngokukhethekileyo, umzekelo, umzekelo, i-6% ye-GlyOxal yeyona ifanelekileyo. Ngokubanzi, ubushushu bonyango luyi-0 ~ 30 ℃, kwaye ixesha ngu-1 ~ 120min. Ukunxibelelanisa ukuphendula okugqogqa kudinga ukwenziwa phantsi kweemeko ze-acidic. Ngokubanzi, isisombululo siqala ukongezwa nge-Inorgan-Acid okanye i-Alboxylic Acid yokutshintsha i-PH yesisombululo malunga ne-2 ~ 6, emva koko yongeza i-Aldesses ukuze iqhubeke nokuphendula ngokudibeneyo. I-acid esetyenzisiweyo ine-hydrochloric acid, i-phosfuric acid, phosphoric acid, i-aceccinic acid, i-succcinic acid icetyiswa, kwaye i-acic acid icetyiswa. I-acid kunye ne-Aldehyde nayo yongezwa kwangaxeshanye ukuvumela isisombululo ukuba sibambelele kwi-ross-cow-vest rees Le mpendulo idla ngokusetyenziswa kwinkqubo yokugqibela yonyango kwinkqubo yokulungiselela ye-seluplose. Emva kokuba i-ether iseti i-itar i-insolline, ilula ukuyisebenzisa
20 ~ 25 ℃ Amanzi ngokuhlamba nokuhlanjululwa. Xa imveliso isetyenziswayo, izinto ze-alkaline zinokongezwa kwisisombululo semveliso ukuze zilungelelanise i-PH yesisombululo ukuba i-alkaline, kwaye imveliso iya kunyibilika kwisisombululo ngokukhawuleza. Le ndlela ikwasebenza nonyango lwefilimu emva kokuba isisombululo se-selsulose sese senziwe kwifilimu yokwenza ifilimu engenanto.
. Iqela ngalinye kwi-chainse yeselselsese ayifani ngokwaneleyo, kwaye i-microorganisms inokukhupha kwiqela le-Anhhydroglucose. I-Sudares yenziwa kwaye ingene njengezondlo kwizilwanyana ezincinci. Ke ngoko, ukuba inqanaba lokufakelwa kwe-etherIsist ye-seluplose yonyuka, ukumelana nokukhukuliseka kwe-erzymatic i-ether eselokhethe iyakonyuka. Ngokweengxelo, phantsi kweemeko ezilawulwayo, iziphumo ze-hydrolysis, i-viscofis entsalela ye-Hydroxylcelsulose (DS = 1.6.9) yi-7.3%, i-methylcelcelculose (DSylcelcellulose (DSY = I-1.7%. Ingabonwa ukuba i-hydroxypropyl methylcelcelculose inamandla aqinileyo i-enzyme. Ke ngoko, i-enzyme egqwesileyo ye-hydroxypropyl methylceltulose, idityaniswa nepropathi yakhe elungileyo, equlatha ifilimu, isetyenziswa kwi-ortings e-emulsion, njl., Kwaye ngokubanzi akufuneki ukuba bongeze izilondolozi. Nangona kunjalo, ukugcinwa kwexesha elide kwesisombululo okanye ukungcoliseka okunokwenzeka ngaphandle, izinto ezigciniweyo zinokongezwa njengezilumkiso, kwaye ukhetho lungagqitywa ngokweemfuno zokugqibela zesisombululo. I-phenylmercuric ye-phenylmercuric acetate kunye ne-manganese flurosilicicial zizinto ezisebenzayo, kodwa zonke zinetyhefu, ingqalelo kufuneka ihlawulwe ekusebenzeni. Ngokubanzi, i-5 ~ 5mg ye-phenylmer ye-phenylmer inokutongezwa kwisisombululo kwilitha nganye yedosi.
. Isisombululo se-accous okanye isisombululo se-organic split sidityaniswe kwiplate yeglasi, kwaye sikhululekile emva komile. Umbala, obonakalayo kunye nefilimu enzima. Inokuthini ukunyangwa okuhle nokunganyangeki kubushushu obuphezulu. Ukuba kongezwa i-hygroscopic plashiptizer, i-elonghation yayo kunye nokuguquguquka kungaphuculwa. Ngokwendlela yokuphucula ukuguquguquka, iiplastiki ezifana ne-glyrin kunye ne-sorbil zilungele kakhulu. Ngokubanzi, ukugxininiswa kwesisombululo yi-2% ~ 3%, kunye nenani lesiqwengana liyi-10% ~ 20% ye-seluplose ether. Ukuba umxholo weplastiki uphezulu kakhulu, ukupheliswa kwehlelo ye-colloidal deves kuya kwenzeka kumswakama ophezulu. Amandla e-sunsed yefilimu eneplastiki eyongezwe inkulu kakhulu kunelo ngaphandle kweplastiki, kwaye iyakonyuka ngokunyuka kwenani elongeziweyo. Ngokuphathelele i-hygroscoficity yefilimu, isonyuka ngokunyuka kwexabiso leplastiki.
