I-hydroxypropyl ye-hydroxlyl

I-hydroxypropyl ye-hydroplopyl ethathiweyo (L-HPC) kukukhupha i-sellyulose, i-polymer yendalo ifunyenwe kwiindonga zeseli zezityalo. I-L-HPC iguqulwe ukomeleza ukugcwaliswa kwayo kunye nezinye iipropathi, zenza ukuba kube yinto eguquguqukayo kwizicelo ezininzi kwizicelo zamayeza, ukutya kunye nemizi-mveliso yeCosmetic.

I-hydroxypropylceluplopylcelose (L-HPC) i-selsuncial ephantsi esungulwa ehletyiweyo ekuphuculwe ngokuyintloko ukuze iphucule ukugcwala kwayo emanzini nasezinyeni. I-seluplose ngumgca we-polysacchaaccharide eqokelelwe kwiiyunithi zeGlucose ezininzi kwindalo kwaye yinxalenye yesakhiwo seendonga zeseli zezityalo. I-L-HPC idityaniswe ngokutshintsha imichiza, ukwazisa amaqela e-hydroxypropy yokuphucula ukuzola kwayo ngelixa ugcina ezinye zeempawu ezinqwenelekayo zeSelelose.

Ubume bemichiza ye-hydroxlyproplopl ye-hydroplopy

Isakhiwo sekhemikhali se-L-HPC siquka i-sellose ye-sellese kunye neqela le-hydroxypropy eqhotyoshelwe kwi-Hydroxyl (Oh) iqela leyunithi ye-glucose. Inqanaba lokufakwa endaweni (DS) libhekisa kwinani eliphakathi lamaqela e-hydroxypropy kwiyunithi ye-glucose nganye kwikhonkco leselselose. Kwi-L-HPC, i-DS igcinwe iphantsi ukuze ilungelelaniswe ukuba isebenze ukwenzela amandla okugcina iipropathi ze-sellulose.

I-Synthesis ye-hydroxyproplopy ye-hydroplopy

I-synthesis ye-L-HPC ibandakanya impendulo yesellulose nge-propylene oxide phambi kobuso be-alkaline. Le ndlela yokuphendula iphumela ekuqaliseni kwamaqela e-hydroxypropy kwimixokelelwane yeselselose. Ukulawulwa ngononophelo kweemeko zokuphendula, kubandakanya ubushushu, ixesha lokuphendula, kunye nokugxininisa kakhulu, kubalulekile ukufezekisa inqanaba lokufakwa endaweni.

Izinto ezichaphazela isomba

1. Inqanaba lokufakwa endaweni (DS):

Ukunyibilika kwe-L-HPC kuchaphazeleka yi-DS yayo. Njengoko i-DS inyuke, i-hydrophility yeqela le-hydroxypropy iba libhengezwe ngaphezulu, ngaloo ndlela iphucule ukungcungcutheka emanzini nasePolar.

2. Ubunzima bemolekyuli:

Ubunzima bemolekyuli ye-L-HPC yenye into ebalulekileyo. Ubunzima obuphezulu bemolekyuli i-M-hpc inokuboniswa ukunciphisa ukuncipha ngenxa yokunyuka kwamandla amaqhosha kunye ne-chanceslements.

3. Ubushushu:

Ukunyibilisela ngokubanzi kubushushu kuba ubushushu obuphezulu bubonelela ngamandla angaphezulu ukuze baphumle amandla amathamsane kwaye bakhuthaze ukunxibelelana kwe-polymer.

4. Ixabiso lesisombululo:

I-PH yesisombululo ichaphazela i-ions yeqela le-hydroxypropy. Ngamanye amaxesha, ukuhlengahlengisa i-pH kunokunyusa i-slobing ye-L-HPC.

5. Uhlobo lwesinyithi:

I-L-HPC ibonakalisa ukubenzela amandla emanzini kunye neendlela ezahlukeneyo ze-porles. Ukhetho lwe-solven luxhomekeke kwisicelo esithile kunye neepropathi eziyinqwenelekayo zemveliso yokugqibela.

Ukusetyenziswa kwe-hydroxypropyl ye-hydroxyl

1. Iziyobisi:

I-L-HPC isetyenziswe ngokubanzi kumzi-mveliso wamayeza njenge-binder, i-Intericrant nelawulwa iarhente yokukhutshwa kwethayile. I-solity yayo kwi-Gastrointentinal ulwelo lwenza ilungele ukusetyenziswa kwezicelo zokuhambisa iziyobisi.

2. Ishishini lokutya:

Kumzi-mveliso wokutya, i-L-HPC isetyenziswa njenge-thi checkener kunye nokuzinza kwiimveliso ezahlukeneyo. Ukwazi kwayo ukwenza i-gene ecacileyo ngaphandle kokuchaphazela incasa okanye umbala weemveliso zokutya kwenza ukuba kube yinkqubo yokutya.

I-3. I-cosmetics:

I-L-HPC isetyenziswa kwiziko le-cosmetic lokwenza iifilimu zefilimu kunye neepropathi ezinkulu. Kuyanceda ukuphucula uzinzo kunye nokuhlengahlengiswa kwezinto ezifana neekhrim, i-lotions kunye ne-gels.

4. Isicelo sokukhetha:

I-L-HPC inokusetyenziswa njengempahla yokugcina ifilimu kumashishini okhuselo kunye nokutya ukubonelela nge-themoctive yetafile okanye iimveliso ze-confectionery.

I-hydroxypropy ye-hydroprespy ye-hydroplopy ye-seluplose i-polymer ye-polymer kunye ne-solbubing ephuculweyo ifunyenwe kwi-selsulose yendalo efumaneka kwizityalo. Ipropathi yayo eyahlukileyo yenza ukuba ixabiseke kumashishini ahlukeneyo kubandakanya amayeza, ukutya kunye ne-cosmetics. Ukuqonda izinto eziphembelela ukunyibilikisa kwalo kubalulekile ukwenza ukusetyenziswa kwayo kwizicelo ezahlukeneyo. Njengoko uphando lweSayensi yePolymer kunye noPhuculo luyaqhubeka, i-L-HPC kunye nezakhiwo ezifanayo zeSeletulose zinokufumana izicelo ezitsha nezinobuchule kuluhlu lwamacandelo.
