Hydroxypropyl methylcelculose (hpmc)Ngaba i-polymer esetyenziswe ngokubanzi kwimizi-mveliso eyahlukeneyo, kubandakanya amayeza, ukutya, ukwakhiwa kunye ne-cosmetics. Uhlobo lwayo ludlala indima ebalulekileyo kwizicelo zayo. Ukuqonda izinto ezichaphazela ukuveliswa kwe-HPMC Viscofity Viscosity ibalulekile ekuqhubeni intsebenzo yayo kwiimeko ezahlukeneyo. Ngokuhlalutya ngokuqonda ezi zinto, abathathi-nxaxheba banokusebenzisa ngcono iipropathi ze-HPMC zokufezekisa iimfuno ezithile zesicelo.

Intshayelelo:
I-HydroxyPOpyl Methylcelcelsele (i-HPMC) yi-Polymer ye-Pelymer enezicelo ezixhaphakileyo ezilawula iipropathi zayo ezizodwa, kubandakanya nokuzola kwamanzi, ubuchule bokwenza ifilimu, kunye ne-filimus-filimu, kunye ne-filimuc yokwakha ifilimu, kunye ne-filimuc yokwakha ifilimu, kunye ne-filit-nefilimuc yokwakha ifilimu, kunye ne-filit-nefilimuc yokwakha ifilimu, kunye ne-filit-nefil-nefil-nefil-nefil-yefilimu, kunye ne-filit-nefilimung yefilimu, kunye nefilimu. Omnye weparameter ebalulekileyo echaphazela intsebenzo yayo ngulonwabo. UVenkile weZilungitho ze-HPMC ufumana indlela yokuziphatha kwayo kwizicelo ezahlukeneyo, njengokuthamba, ukugcwala, ukukhululeka kwefilimu, kunye nokukhululwa okuzinzileyo kwimigaqo yamayeza. Ukuqonda izinto ezilawula ukuveliswa kwemveliso ye-HPMC ye-HPMC ye-HPMC yeyona nto iphambili ekusebenzeni kwayo kumashishini ahlukeneyo.

Izinto ezichaphazela imveliso ye-HPMC ye-HPMC:

Ubunzima bemolekyuli:
Ubunzima bemoyaI-HPMCichaphazela kakhulu impembelelo yothando lwayo. I-polymers ephezulu yemolekyuli ibonakalisa i-viscofity ephezulu ngenxa yokunyuka kwe-chain. Nangona kunjalo, ubunzima obukhulu kakhulu bemolekyuli bunokukhokelela kwimiceli mngeni kwizisombululo kunye nokulungiswa. Ke ngoko, ukukhetha uluhlu lwe-molecular ofanelekileyo kubalulekile ekulileni kweemfuno zokubonisa.

Inqanaba lokufakwa endaweni (DS):
Inqanaba lokufaka endaweni lubhekisa kwinani le-hydroxypropy ye-hydropyl kunye ne-AFGISSS ePhezulu kwiYunithi ye-Anhhydroglucose kwi-selsulose chain. Amaxabiso aphezulu e-ds akhokelela kwi-viscofity ephezulu ngenxa yokwanda kwe-hydrophicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicity kunye nonxibelelwano. Nangona kunjalo, ukwabana ngokugqithisileyo kunokukhokelela ekunciphiseni ukulingana kunye notyekelo lwe-gesing. Ke ngoko, ukulungiselela i-DS kubalulekile ekufezekiseni i-vickosity efunekayo ngelixa ugcina uzombise kunye nokuziqhelanisa.

Uxinzelelo:
I-HPMC Viscosity ihambelana ngokuthe ngqo kwixinzelelo lwayo kwisisombululo. Njengoko i-polymere yoxiniso lonyuka, inani lamakhonkco ePolymere nganye kwiCandelo lokuQeqeshwa kwakhona, ekhokelela ekuphuculeni i-chancelity eqinisekisiweyo kunye nokuvalelwa okuphezulu. Nangona kunjalo, kwiindlela eziphezulu kakhulu, uVekyusity unokuphelisa okanye ukwehla ngenxa yokuhlangana kwePolymer-Polymer kunye nokwakhiwa kwejeli. Ke ngoko, ukwenza uxinzelelo kubalulekile ekufezekiseni i-viscofity enqwenelekayo ngaphandle kokuzinza kwesisombululo.

Iqondo lokushisa:
Iqondo lokushisa linempembelelo ebonakalayo kuhlobo lwe-HPMC. Ngokubanzi, i-viscosity inciphisa ubushushu obukhulayo ngenxa yokuncitshiswa kwendlela yePolymer-Polymer Polymer kunye nokuphuculwa kokuhamba kwemolekyuli. Nangona kunjalo, esi siphumo sinokwahluka ngokuxhomekeka kwizinto ezinje nge-polymer gxini, ubunzima bemolekyuli, kunye nonxibelelwano oluthile kunye nezixhobo. Imvakalelo yobushushu kufuneka ithathelwe ingqalelo xa ilungiselela iimveliso ezisekwe i-HPMC ukuqinisekisa ukusebenza okungaguqukiyo kwiimeko ezahlukeneyo zobushushu.

Ph:
I-PH yesisombululo ichaphazela i-hpmc viscosity ngokwenziwayo kwi-Polymer Solubaility kunye neNgcaciso. I-HPMC inyibilikisa kakhulu kwaye ibonise i-vidity ephezulu kakhulu kwi-acidic kancinci kwi-acidic ye-pron engathathi hlangothi. Ukuphambuka kolu luhlu lwe-PH kunokukhokelela ekunciphiseni ukuncipha kunye nokugcinwa kwe-viscofity ngenxa yotshintsho kwi-polymer conformation kunye nokudibana kweemolekyuli zeSolvent. Ke ngoko, ukugcina iimeko ezifanelekileyo kubalulekile ukuze kwandiswe i-hpmc viscosity kwisisombululo.

Izongezo:
Iikomishini ezahlukeneyo, ezinjengeetyus, i-surfcantints, kunye nezicombulo ze-HE, zinokuchaphazela i-HPMC Viscofity ngokusebenzisa iipropathi zesisombululo kunye nokusebenzisana kwe-polymer. Umzekelo, iityuwa zinokuphembelela ukuphucula i-viscofity ngokusebenzisa isiphumo sokutsalwa kwetyala, ngelixa i-tionspicals inokuba nefuthe kuxinzelelo lomphezulu kunye nokubenzela i-polymer. Izicombululi zinokuguqula i-polvent poilsecy kunye nokomeleza ukuzala kwePolymer kunye noVeksity. Nangona kunjalo, ukuhambelana nokunxibelelana phakathi kwe-HPMC kunye nezongezo kufuneka kuhlolwe ngononophelo ukuthintela iziphumo ezingafunekiyo kwi-viscofity kunye nokusebenza kwemveliso.

Ngaba i-polymer eguquguqukayo isetyenziswe ngokubanzi kwindawo yamayeza, ukutya, ukwakhiwa, kunye nemizi mveliso yenkcitho. Uhlobo lwezisombululo ze-HPMC udlala indima ebalulekileyo ekumiseleni ukusebenza kwayo kwizicelo ezahlukeneyo. Ukuqonda izinto ezichaphazela ukuveliswa kwe-HPMC Viscosity, kubandakanya ubunzima bemolekyuli, isidanga sokufakwa, uxinzelelo, ubushushu, i-PH, kwaye ibalulekile ekusebenzeni kwayo kunye nokusebenza kwayo. Ngokuguqula ngononophelo ezi zinto, abathathi-nxaxheba banokulinganisa iipropathi ze-HPMC zokufezekisa iimfuno ezithile zesicelo ngokukuko. Uphando oluthe kratya phakathi kwezi zinto luya kuqhubeka nokuqhubela phambili ukuqonda kwethu kunye nokusetyenziswa kwe-HPMC kumacandelo ahlukeneyo ezikomishini.
