Ukutolikwa kwe-Hydroxypropy I-Methylcelcelcelse HPMC Iingxaki

1. Zininzi iintlobo ze-hydroxypropyl methylcelceluplose hpmc, kwaye yintoni umahluko phakathi kokusetyenziswa kwabo?

Impendulo: I-HydroxyPOpyl Methylcelceltulose HPMC inokwahlulwa kuba luhlobo lwangoko kunye nohlobo olushushu. Iimveliso zemodi zethutyana zisasaza ngokukhawuleza emanzini abandayo kwaye zinyamalala emanzini. Ngeli xesha, ulwelo alunanto yokufakwa, kuba i-HPMC ichithwa njengamanzi, akukho ntlawulo yokwenene. Emva kwemizuzu emi-2, i-viscosity ye-ulwelo ngokuthe ngcembe yanda, yakha i-viscous ebonakalayo. Iimveliso ezishushu ezishushu, xa zidibene namanzi abandayo, zinokusasaza ngokukhawuleza emanzini ashushu kwaye zinyamalala emanzini ashushu. Xa iqondo lobushushu liye kwehla kubushushu obuthile, i-vickosity ivela kancinci de i-vicous engabonakaliyo yenziwa. Uhlobo olushushu olushushu lunokusetyenziswa kuphela kwi-podty powder nodaka. Kwiglue yeglue kunye nepeyinti, ukubethwa kuka-Likedon kuya kwenzeka kwaye akunakusetyenziswa. Uhlobo lwethutyana lunoluhlu olubanzi lwezicelo. Ingasetyenziswa kwi-poceble yomgubo kunye nodaka, kunye neglu yolwelo kunye nepeyinti, ngaphandle kokuphikisana.

2. Yeyiphi eyona njongo ye-hydroxypropyl methylcelcelcelsulose (HPMC)?

I-A: i-HPMC isetyenziswa ngokubanzi kwizinto zokwakha, iingubo, i-resings, i-ceramic, i-ceramic, i-ceramic, i-lests, i-cosmetics, amashishini kunye namanye amashishini. I-HPMC inokwahlulwa ibe: Ibanga lokwakha, iBanga lokutya kunye namayeza ngokwenjongo. Okwangoku, uninzi lweemveliso zasekhaya libakala lokwakha. Kwinqanaba lokwakha, isixa se-potty powder sikhulu kakhulu, malunga ne-90% isetyenziselwa umgubo ongezantsi, kwaye okuseleyo kusetyenziselwa ukuqina kwesamente kunye neglu.

3. Zithini iindlela zokuchithwa kwe-hydroxypropyl methylcelcelcelgalose hpmc?

Impendulo: Indlela yokuchithwa kwamanzi ashushu: Oko i-HPMC ayichithwanga emanzini ashushu, i-HPMC inokuba isasazeke ngendlela efanayo kumanzi ashushu kwindawo yokuqala, emva koko inyibilikiswe ngokukhawuleza. Iindlela ezimbini eziqhelekileyo zichazwe ngolu hlobo lulandelayo:

1), Yongeza i-1/3 okanye i-2/3 yexabiso elifunekayo lamanzi kwisikhongozelo, kwaye usitshise ukuya kwi-70 ° C, ngokwe-HPMC, lungisa amanzi ashushu. Emva koko yongeza inani elisele lamanzi abandayo ukuya kwamanzi ashushu kwi-slirry, umxube wapholwa emva kokuvuselela.

Indlela yokuxuba i-powder Umgubo uya kunyibilikisa ngoko nangoko kunxibelelana namanzi. Indlela ye--tis isetyenziswa yi-putty powder kunye nabavelisi bodaka. [HYDROXYPOPLL methylcelceltulose (i-HPMC) isetyenziswa njenge-tickener kunye nearhente yokugcina amanzi kumda we-podty powder.

2), faka inani elifunekayo lamanzi ashushu kwisitya, kwaye uyitshise malunga nama-70 ℃. I-hydroxypropyl methylcelcelsulose yongezwa ngokuthe ngcembe, ekuqaleni i-HPMC ifakwe kumphezulu wamanzi, emva koko yazenzela ngokuthe ngcembe isilayidi.

4. Ungawugweba njani umgangatho we-hydroxypropyl methylcelculose (i-HPMC) ngokulula nangokuthathelayo?

Impendulo: (1) Ubuninzi obuthile: Kuyinto enkulu umxhuzulane okuthile, ubunzima obunzima. bukhulu, ngokufuthi kuba

. Nangona kunjalo, uninzi lweemveliso ezilungileyo lube mhlophe mhlophe.

. Uninzi lwe-HPMC eveliswe eHebei yi-80 mesh. Ukulungisa ubuhle, kungcono ngokubanzi.

. Ukuphakama okuphezulu, ngcono, kubonisa ukuba kukho izinto ezingafunekiyo ngaphakathi. Ukukhohlisa kweesandi ezithe nkqo zihlala zilungile, kwaye ukuba iisandla ezivuthayo zibi, kodwa akunakuthethwa ukuba umgangatho wokuphendula ngokuthe nkqo ungcono, kwaye zininzi izinto ezimisela umgangatho weemveliso. Umxholo we-hydroxypropy ukuphakama, kwaye umxholo we-hydropypy up, ukugcinwa kwamanzi kungcono.

5. Zeziphi izikhombisi eziphambili ze-hydropypropyl methylcelculose (i-HPMC)?

Impendulo: I-HYDROXDYPOPYL Umxholo kunye ne-viscofity, uninzi lwabasebenzisi abakhathalelayo ezi zikhombisi zimbini. Ngaphezulu komxholo we-hydroxypropy, kungcono ukugcinwa kwamanzi. I-Vicous, ukubamba amanzi, ngokulinganayo (endaweni ye

6. Luthini uVekyusis ofanelekileyo we-hydroxypropyl methylcelcellulose (HPMC)?

Impendulo: I-Putty Powder ikakhulu yi-100,000 yuan, kwaye udaka ifuna ngakumbi, kwaye kulula ukuyisebenzisa kwi-150,000 yuan. Ngaphezu koko, eyona ndima ibaluleke kakhulu ye-HPMC kukugcina amanzi, kulandelwe ngokulandelelana. E-Putty Powder, logama nje ukugcinwa kwamanzi kulungile kwaye i-viscosity iphantsi (70,000-80,000), kunokwenzeka. Ewe kunjalo, ukuba i-vickosity iphezulu, ukugcinwa kwamanzi okuhlala kungcono. Xa i-viscosity idlula i-100,000, isiphumo sokujonga ukugcinwa kwamanzi akuninzi. Ngokuqinisekileyo) nangcono, kwaye i-vickosity iphezulu, kwaye kungcono ukuyisebenzisa esimemeni.

7. Zeziphi izixhobo eziphambili ze-hydroxypropyl methylcelcelgalose (HPMC)?

Impendulo: Ezona zinto ziphambili ze-HydroxyPOpyl MethylcelcelUlose (HPMC): I-HPMC ecocekileyo, i-methyl oxide, i-propylene oxide, i-propylene iquka i-Alkali, i-Acid, i-toonene, i-Iyopropanol, njl.
