Ngaba uyayazi ukusebenza kwe-hydroxypropyl methylcelgulose?

I-HydroxyPOpyl Methylcelcelcelose luhlobo lwe-unic se-ionic sether exutywe. Ngokungafaniyo ne-Ionic Methyl Carboxymethyl Setelose Telupe Ter, ayiphenduli ngeentsimbi ezinzima. Ngenxa yomyinge ohlukeneyo we-APENGSYL kufutshane ne-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

① Sobubing ye-Hydroxypropyl Methylcelcelcelse in Ane hydroxlypropyl Methylcelcelcel 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-roversid hydropyl methylcelcelgalose (i-Granular I-0.2 ~ 0.5mm nge-20% ye-ASCity ye-AGCIT SOTE

② Ukucekisa i-Shydroxypropyl Methylcelcelgalose i-Sorpopy i-Soling ye-Shoubing ye-Hydroxypropyl Methylceluplose kwi-mithylcelsulose. I-methylcelsulose kufuneka isebenze ngayo inqanaba le-2.1 Ezi mveliso zingasentla, kodwa zinee-hydroxypropyl NS = 0.2 ~ I-Thermos-pristity kunye nokuhluma kwamanzi. 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.

. Ilinganiswa nge-20 ° C ene-2% ye-2% ye-acteous njengomgangatho. Uhlobo lwemveliso olufanayo luyanda ngokunyusa uxinzelelo. 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 ukuhla, 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. Kuya kufuneka kuqatshelwe ukuba i-hydroxypropyl methylcelcelistic ikwangu-pseudopticy, kwaye isisombululo sayo sizinzile kubushushu begumbi ngaphandle kokuthathwa kwe-viszmatic.

. 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, isixa esithile setyuwa yongezwa, kwisicelo, inokufezekisa ifuthe lokufundisa ngakumbi kwezoqoqosho. Ke ngoko, kwezinye iinkqubo, kungcono ukusebenzisa umxube we-selsulose ether kunye netyuwa kunesisombululo esiphezulu sokufezekisa isiphumo sokuqaqamba.

. Inokumelana nesixa esithile se-acid ukukhanya, njenge-forcid acid, i-ciccric acid, i-phosccinic acid, i-acid ye-phoric acid inesiphumo sokunciphisa i-viscofity. 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-polyethylene glycol, polyvingl acetate, polysililicone, polymethylviny,, i-pulymethylvingl siloxane, kunye ne-methyl seluplose. 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. Umthamo wolu hlobo lwe-arhente yokudibanisa isisombululo 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. Ukuphendula okuphezulu kufuneka kwenziwe phantsi kweemeko ze-acidic. Ngokubanzi, i-PH yesisombululo ihlengahlengiswa malunga ne-2 ~ 6 ngokongeza i-Inorgan-Acid okanye i-Alboxylic Acid isisisombululo kwisisombululo, ngokukhethekileyo phakathi kwe-4 ~ 6, kwaye emva koko i-Aldelweni yongezwa ukuze isebenze. I-ACID esetyenzisiweyo ine-hydrochloric acid, i-phosfuric acid, i-phosphoric acid, i-acetic acid, i-succinic acid okanye i-ciccinic acid icetyiswa, kwaye i-acid ye-fickic icetyiswayo, 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 i-seluplose i-insulle, 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.

. Ukufakwa kweqela ngalinye kwi-Cleulose Chain ayifani ngokwaneleyo, kwaye i-microorganisms inokukhupha kwiqela le-anhydroglucose e-Anhydroglucose ukwenza iswekile, njengezondlo kwi-microorganism. 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 zenziwe, i-viscofity ye-Hydroxypropyl Methylcelsulose (DS = 1.66) yi-7.8%, kunye ne-hydroxyythl seluplose yi-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 selvent sidityaniswe kwipleyiti yeglasi, kwaye iba ngumbala kwaye ibonakala emva komile. 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.
