Ukuthetha nge-hydroxypropyl methyl seluplose (hpmc)

1. Yintoni i-alias ye-hydroxypropyl methylcelcelceluplose?

-I-SHDHERPYL I-MTHYL I-ItyUlose, English: Hydroxypropyl Methyl Ityheli: I-HPMC Alias: Hyplellose; I-seluplose hydroxyropyl methyl thother; I-Hypromellose, Selelise, 2 - Xhosa-Hydroxypropythyl Selerse. Seluplose hydroxypropyl methyl herrolose hyprolose.

2. Sisiphi esona sicelo siphambili se-hydroxypropyl methylcelcelculose (i-HPMC)?

-I-Answer: I-HPMC isetyenziswa ngokubanzi kwizixhobo zokwakha, iingubo, i-reatsins, i-ceramic, i-ceramics, ukutya, i-cosmetics, icuba kunye namanye amashishini. I-HPMC inokwahlulwa ibe yeyaba kwinqanaba lokwakha, inqanaba lokutya kunye namayeza ngokwenjongo. Okwangoku, uninzi lweemveliso zasekhaya libakala lokwakha. Kwibanga lokwakha, i-popy powder isetyenziswa kwisixa esikhulu, malunga ne-90% isetyenziselwa umgubo ongezantsi, kwaye okuseleyo kusetyenziselwa ukuqina kwesamente kunye neglue.

3. Kukho iintlobo ezininzi ze-hydroxypropyl methylcelculose (i-HPMC), kwaye yintoni umahluko ekusebenziseni kwabo?

I--Answer: I-HPMC inokwahlulwa ibe luhlobo lwethutyana kunye nodidi olushushu. I-Chwetheza iimveliso zethutyana zisasaza ngokukhawuleza emanzini abandayo kwaye inyamalale emanzini. Ngeli xesha, ulwelo alunanto yokuba i-HPMC ichithwa njengamanzi ngaphandle kokupheliswa kokwenene. Malunga nemizuzu emi-2, i-viscosity ye-ulwelo ngokuthe ngcembe inyuka, yenza i-collous ebonakalayo colous collous. Iimveliso ezishushu-zinyibilikisa, xa zidibene namanzi abandayo, zinokusasaza ngokukhawuleza emanzini ashushu kwaye zinyamalala emanzini ashushu. Xa iqondo lobushushu liyelela kubushushu obuthile, i-viscofity iya kuvela kancinci ide ibe yi-collous engabonakaliyo. Uhlobo olushushu olushushu lunokusetyenziswa kuphela kwi-podty powder nodaka. Kwiglue yeglue kunye nepeyinti, kuya kubakho i-phenomenong yeqela kwaye ayinakusetyenziswa. Uhlobo lwethutyana lunoluhlu olubanzi lwezicelo. Ingasetyenziselwa umgubo we-potty kunye nodaka, kunye neglue engamanzi kunye nepeyinti, ngaphandle kokuphikisana.

4. Ungayikhetha njani i-Hydropyl ye-hythylcelculose (i-HPMC) yeenjongo ezahlukeneyo?

-Anzi-jensi: Into ebalulekileyo kukugcina amanzi kakuhle. Ukusetyenziswa kodaka: Iimfuno eziphezulu, i-viscofity ephezulu, i-150,000 ingcono. Ukusetyenziswa kweGlue: Iimveliso ezikhawulezileyo ezinokufunwa kwi-viscofity ephezulu.

5. Yintoni ekufuneka ithathelwe ingqalelo kwisicelo sobudlelwane phakathi kwe-viscofity kunye neqondo lobushushu le-HPMC?

-I -ansity: I-viscosity ye-HPMC ihambelana ngokulinganayo kubushushu, oko kukuthi, i-viscosity inyuka njengoko ubushushu bunciphisa. UVenkile weMveliso Sihlala sibhekisa kwi-2% ye-ACDEACOOR YENKCAZO YAMA-20 degrees Celsius.

Kwizicelo ezisebenzayo, kufuneka kuqatshelwe ukuba kwiindawo ezinomahluko omkhulu phakathi kwehlobo nasebusika, kucetyiswa ukuba basebenzise i-viscofity ephantsi ebusika, okukhululekileyo ekwakheni. Ngaphandle koko, xa iqondo lobushushu liphantsi, i-viscosity yesellulose iya kunyuka, kwaye isandla siziva sinzima xa sikhupha.

I-vickosity ephakathi: 75000-100000 isetyenziselwa i-putty

Isizathu: Ukugcinwa kwamanzi kakuhle

I-viscofity ephezulu: i-150000-200000 isetyenziselwa i-Polystrene ye-Polystyrene i-thermal iposti yerabha kunye ne-vitbed i-vitbed i-thermal incuter.

Isizathu: UVICWASITY uphezulu, udaka akukho lula ukuwa, i-SAG, nolwakhiwo luphuculwe.

I-6. I-HPMC yi-unic se-i-ionsulose ether, ke yintoni ingento ingento?

-I-Answern: Kwimigaqo ye-DALMENT, i-ions zizinto ezingasebenziyo emanzini. I-ioris ibhekisa kwinkqubo apho i-electrolyte ihluthwe kwii-Ions ezinokuhamba ngokukhululekileyo kwi-Solvent ekhethekileyo (njengamanzi, utywala). Umzekelo, i-sodium chloride (i-NACL), ityuwa esiyitya yonke imihla, inyibilikiswe emanzini kwaye i-Ionid ukuvelisa i-Ions ye-sodium esuswe ngokukhululekileyo kunye ne-chloride i-ions (CLI) ezihlawuliswa kakubi. Oko kukuthi, xa i-HPMC ifakwe emanzini, ayiyi kukhokelela kwi-Ions, kodwa ikho ngohlobo lweeMolekyuli.
