Yintoni i-viscosity ye-cellulose ether?

I-Viscosity yipropathi ebalulekileyo ekuqondeni ukuziphatha kolwelo, kubandakanywa ne-cellulose ethers.I-cellulose ethers liqela lee-organic compounds eziphuma kwi-cellulose, i-polymer eyenzeka ngokwemvelo efumaneka kwizityalo.Ezi ether zisetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yeempawu zabo ezizodwa, kubandakanywa nokuguqulwa kwe-viscosity.

1. Intshayelelo yeCellulose Ethers:

I-cellulose ethers ziphuma kwi-cellulose efunyenwe ngokuguqulwa kweekhemikhali.Imizekelo eqhelekileyo ibandakanya i-methylcellulose, i-ethylcellulose, i-hydroxypropylcellulose, kunye ne-hydroxyethylcellulose.Ezi khompawundi zibonakaliswa ubunzima bazo obuphezulu bemolekyuli kunye nobukho bamaqela e-hydroxyl, ezenza ukuba zinyibilike emanzini kunye ne-organic solvents ukuya kumaqondo ahlukeneyo.

2. Ukubaluleka kweViscosity:

I-Viscosity ngumlinganiselo wokuxhathisa kolwelo ukuhamba.Kwimeko ye-cellulose ethers, i-viscosity idlala indima ebalulekileyo ekuqinisekiseni ukufaneleka kwazo kwizicelo ezahlukeneyo.Ngokomzekelo, kwishishini lokutya, i-viscosity ichaphazela ukuthungwa kunye nomlomo weemveliso ezifana neesosi kunye nokunxiba.Kwimichiza, ichaphazela ukuhambelana kunye nokusabalalisa kwamafutha kunye nama-creams.Ke, ukuqonda kunye nokulawula i-viscosity kubalulekile ekuphuculeni ukusebenza kwemveliso.

3. Izinto ezichaphazela iViscosity:

Izinto ezininzi zinefuthe kwi-viscosity ye-cellulose ethers:

Ubunzima beMolekyuli: Ubunzima obuphezulu bemolekyuli bukhokelela kwi-viscosity ephezulu ngenxa yokwanda kwekhonkco.

Inqanaba lokutshintsha: Iqondo lokutshintshwa kwamaqela e-ether kwi-backbone ye-cellulose ichaphazela ukunyibilika kwaye, ngenxa yoko, i-viscosity.

Ubushushu: I-Viscosity iyancipha ngokunyuka kwamaqondo obushushu ngenxa yokuncipha kwentsebenziswano yeemolekyuli.

Ugxininiso: Uxinzelelo oluphezulu lwe-cellulose ethers kaninzi lukhokelela kwi-viscosity ephezulu, kulandela ubudlelwane obungeyo-linear.

4. Iindlela zoMlinganiso:

I-viscosity inokulinganiswa kusetyenziswa iindlela ezahlukeneyo:

I-Viscometry ejikelezayo: Ngokuqhelekileyo isetyenziselwa izisombululo kunye nokumiswa, le ndlela ibandakanya ukulinganisa i-torque efunekayo ukujikeleza i-spindle kulwelo.

I-Capillary Viscometry: Obu buchule bulinganisa ixesha elithathwayo ukuze ulwelo luhambe ityhubhu ye-capillary phantsi koxinzelelo oluchaziweyo.

I-Rheology: Imilinganiselo ye-Rheological inika ingqiqo malunga nendlela into eguquka ngayo phantsi koxinzelelo, kuquka ukucheba kunye ne-viscosity emide.

5. Ukusetyenziswa kweCellulose Ethers:

I-Cellulose ethers ifumana usetyenziso kuwo wonke amashishini awohlukeneyo:

Ukutya: Kusetyenziswa njengezinto ezityebileyo, izizinzi, kunye nezithambiso kwiimveliso ezifana ne-ayisikrimu, iyogathi, kunye nezinxibo zesaladi.

Amachiza: Baqeshwe njengabadibanisi, abaqhankqalazi, kunye nabaqulunqi beefilimu kwiifom zepilisi, i-ointments, kunye nokumiswa.

Ulwakhiwo: Ukongezwa kwisamente kunye nodaka ukuphucula ukusebenza, ukugcinwa kwamanzi, kunye nokunamathela.

Ukhathalelo lobuqu: Ibandakanywe kwizinto zokuthambisa, iishampu, kunye nezinto zokuthambisa ngenxa yokujiya kunye neempawu zegelling.

6. Iindlela zexesha elizayo kunye nemingeni:

Imfuno ye-cellulose ethers kulindeleke ukuba ikhule, iqhutywa kukwanda kwezicelo kwikhemistri eluhlaza, i-biomedicine, kunye nezixhobo eziphambili.Nangona kunjalo, imiceli mngeni efana nokukhuphisana kweendleko, iinkxalabo zolawulo, kunye nesidingo sokufumana iindlela ezizinzileyo kunye neendlela zemveliso zihleli.

7. Isiphelo:

i-viscosity ye-cellulose ethers yiparameter ebalulekileyo echaphazela ukusebenza kwabo kwizicelo ezahlukeneyo.Ukuqonda izinto ezichaphazela i-viscosity kunye nokusetyenziswa kobuchule obufanelekileyo bokulinganisa kubalulekile ekuphuculeni ukwakhiwa kwemveliso kunye neenkqubo.Njengoko imizi-mveliso iqhubeka nokwenza izinto ezintsha, ii-ether ze-cellulose zinokudlala indima ebaluleke kakhulu ekubumbeni ikamva lemathiriyeli yesayensi kunye netekhnoloji.

i-viscosity ye-cellulose ethers ngumba onzima kodwa oyimfuneko ochaphazela ukusebenza kwazo kumashishini awohlukeneyo.Ngokuqonda ukubaluleka kwayo, izinto eziyiphembelelayo, ubuchule bokulinganisa, kunye nokusetyenziswa, abaphandi kunye neengcali banokusebenzisa ngokukuko ii-ether ze-cellulose kwiinkalo ezahlukeneyo, igalelo kwinkqubela phambili kwisayensi kunye netekhnoloji yemathiriyeli.
