1. Iyini inhloso esemqoka ye-HPMC?
Lo mkhiqizo usetshenziswa njengesikhulu, i-distrantint, i-binder, i-excipient, ukumelana namafutha, ukugcoba okuvimbela uwoyela, i-filler, emulsifier kanye ne-stabilizer embonini yezindwangu. Iphinde isetshenziswe kabanzi ku-sonthetic resin, i-petrochemical, ceramic, iphepha, isikhumba, umuthi, izimboni zezimonyo.
2. Iyini indima ye-HPMC engxenyeni yangaphakathi yodonga lwe-putty powder?
I-HPMC inemisebenzi emithathu: i-putty powder yodonga lwangaphakathi, ukuqina, ukukhiya amanzi nokwakha. Ukuhlushwa: I-methyl celtule Ukukhiya Amanzi: I-Interior Wall Pofter Yomisa kancane, futhi i-lime calcium eyengeziwe ikhonjiswa ekusebenziseni amanzi. Ukwakha ubunjiniyela I-HPMC ayibambi iqhaza ekushintsheni kwawo wonke amakhemikhali, kepha abamba iqhaza kuphela ekubuyiselweni kabusha. Udonga lwangaphakathi lwe-Putty powder, odongeni, luwushintsho lwamakhemikhali, ngoba kunokuguqulwa okusha kwamakhemikhali, i-wanga elingaphakathi le-putty powder lisuswa odongeni, likhule, futhi lasetshenziswa, ngoba likhiqizwe kabusha, ngoba likhiqizwe kabusha, ngoba likhiqizwe kabusha, ngoba likhiqizwe kabusha, ngoba likhiqizwe kabusha, ngoba i-calcium bicarbonate) ikhiqizwa. Izakhi eziphambili ze-Grey Calcium Powder yilezi: Ingxube ye-CA (OH) 2, i-CAO + H2O = 2 uqobo.
3. Ungahlulela kanjani ikhwalithi ye-HPMC kalula futhi ngokuqondile?
. Kodwa-ke, imikhiqizo emihle inombala omuhle. . Ubuciko obuhle, okungcono ngokujwayelekile. (3) Ukudluliselwa: Beka i-Hydroxypropylll methylcellulose (HPMC) emanzini ukwakha i-colloid esobala, bese ubheka ukudluliselwa kwalo. Lapho kudlula khona okudlulayo, okungcono, okubonisa ukuthi kukhona okungabonakali okuncane ngaphakathi. . Ukugcwaliseka kwe-reactor mpo ngokuvamile kulungile, futhi i-reactor evundlile imbi kakhulu, kepha akusho ukuthi ikhwalithi ye-reactoror mpo ingcono kunaleyo yokuphendula okuvundlile. Ikhwalithi yomkhiqizo isanqunywa yizinto eziningi. (4) Ingxenye: Kukhudlwana ingxenye enkulu, okusindayo kube ngcono. Ukucaciswa okuphezulu kuvame ngenxa yokuqukethwe okuphezulu kwe-hydroxypropyl kuyo, kanye nokuqukethwe okuphezulu kwe-hydroxypropyl, okungcono ukugcinwa kwamanzi.
4. Yini okufanele inakeke lapho usebenzisa i-viscosity kanye nokushisa kwe-HPMC?
I-viscosity ye-HPMC ilingana kakhulu namazinga okushisa, okungukuthi, i-viscosity inyuka njengoba izinga lokushisa lincipha. Imvamisa sithi ukubonwa komkhiqizo kubhekisele umphumela wokuhlola isisombululo sayo esingamanzi esingu-2% emazingeni okushisa angama-20 degrees Celsius. Kuzinhlelo zokusebenza ezisebenzayo, ezindaweni ezinomehluko omkhulu wokushisa phakathi kwehlobo nobusika, kufanele kuqashelwe ukuthi kunconywa ukuthi kusetshenziswe ubusika obuphansi ebusika, okulungele ukwakhiwa. Ngaphandle kwalokho, lapho izinga lokushisa liphansi, ukubonakala kwe-cellulose kuzokwanda, futhi isandla sizozizwa sinzima lapho sikhanyisa.
5. Iziphi izindlela zokuchithwa kwe-HPMC?
Indlela eshisayo yokuchithwa kwamanzi Izindlela ezimbili ezijwayelekile zichazwa njengokulandelayo: 1). Inani lamanzi ashisayo futhi lifuthelwe cishe ngo-70 ° C. Kancane kancane engeza i-hydroxypropyll methylcellulose ngokuvuselelwa kancane, qala i-HPMC entanta ebusweni bamanzi, bese kancane kancane bakha i-slurry, bese bephola kancane kancane ngokuvusa. 2). Faka u-1/3 noma 2/3 wenani elidingekayo lamanzi esitsheni bese usishisa ku-70 ° C. Ngokwendlela ye-1), isabalalisa i-HPMC ukulungiselela ama-slurry amanzi ashisayo; Ngemuva kwalokho engeza inani elisele lamanzi abandayo emanzini ashisayo ku-slurry, upholile ingxube ngemuva kokuvusa. Indlela yokuxuba ye-powder: hlanganisa i-hpmc powder enesamba esikhulu sezinye izinto ze-powdery, hlanganisa kahle nge-blender, bese ufaka amanzi ukuze uncibilike, khona-ke i-hpmc ngayinye i-HPMC kuphela i-HPMC kuphela i-powder. Abakhiqizi be-powder nabakwaModu basebenzisa le ndlela. [I-Hydroxypropylm Methyl Cellulose (HPMC) isetshenziswa njenge-gentmener kanye ne-ejenti yokugcina amanzi ePutty Powder woduta. [Zosokhu
6. Yiniisilinganiso somuthiye-HPMC ingezwe ku-putty powder?
Inani le-HPMC elisetshenziswe kuzinhlelo zokusebenza zangempela liyahlukahluka ngokuya ngesimo sezulu, izinga lokushisa, ikhwalithi yendawo ye-Ash calcium, nefomula ye-putty powder, ne- "Ikhwalithi edingwa amakhasimende". Ngokuvamile, kuphakathi kuka-4 kg no-5 kg. Isibonelo, i-putty powder emhlobisweni '> i-Beijing iningi lawo lingu-5 kg; I-Putty Powder eGuizhou iningi lama-kg ehlobo no-4,5 kg ebusika; Inani elingezansi likaYunnan lincane, ngokuvamile ama-3 kg-4 kg nokunye.
