I-Hydroxypropyl methylcellulose - Isixazululo

Ibanga le-Industrial Grade Hydroxypropyllylyl methylsylyl metrulose ngodaka ukuhlukanisa i-viscosity, okuvame ukusetshenziswa yinaba amabanga ambalwa alandelayo (iyunithi i-viscosity)

1. I-Viscosity ephansi: I-400 isetshenziselwa ikakhulukazi udaka oluzenzakalelayo, kepha ngokuvamile angeniswa.

Isizathu: Ukubonakaliswa okuphansi, yize ukugcinwa kwamanzi okumpofu, kepha ukugqama okuhle, ukuhlanganiswa okuphezulu kodaka.

2. I-VIVCOSIty ephakathi nephansi

Isizathu: Ukwakhiwa okuhle, amanzi amancane, ubuningi obuphezulu bodaka.

1, yini ukusetshenziswa okuyinhloko kwe-hydroxypropyllylylylylylylylylylyll methyl cellulose (HPMC)?

I-HPMC isetshenziswa kabanzi ezintweni zokwakha, izimbobo, ama-desin zokwenziwa, ubumba - ubumba, umuthi, ukudla, izimbotshana, ugwayi kanye nezinye izimboni. I-HPMC ingahlukaniswa ihlukaniswe: Ibanga lokwakha, ibanga lokudla kanye nebanga lezokwelashwa ngokusetshenziswa. Njengamanje, iningi lebanga lokwakhiwa kwasekhaya, ebangeni lokwakha, umthamo we-putty powder mkhulu, cishe ama-90% asetshenziselwa ukwenza i-putty powder, okusetshenziselwa ukwenza usimende nosimende.

2, i-hydroxypropyl methyl cellulose (HPMC) ihlukaniswe yaba ziningi, yini umehluko ekusetshenzisweni kwawo?

I-HPMC ingahlukaniswa ngohlobo lwesixazululo esisheshayo nesishisayo, imikhiqizo esheshayo, emanzi abandayo ihlakazeke ngokushesha, ingabe idlalwa emanzini, ngoba i-HPMC ingenakubonakala nje emanzini, akukho ukuhlukaniswa kwangempela. Cishe imizuzu emi-2, i-viscosity yoketshezi inyuka kancane, yakha i-colloid esobala ye-volcous. Imikhiqizo eshisayo eshisayo, emanzini abandayo, ingahlakazeka ngokushesha emanzini ashisayo, inyamalale emanzini ashisayo, lapho amazinga okushisa ehla emazingeni okushisa athile, ukubonakala kancane kancane, kuze kusungulwe i-colloid esobala ye-volcous. Isixazululo esishisayo singasetshenziswa kuphela ku-putty powder kanye nodaka, ku-glue key uketshezi, kuzoba ne-phenomenon yeqembu, ngeke isetshenziswe. Imodeli yesixazululo esisheshayo, uhla lwesicelo lubanzi olubanzi, lube nesithukuthezi nge-powder yengane nodaka, bese ku-glue ketshezi, konke kungasebenzisa, ngaphandle kwalokho okuphambene.

3, Hydroxypropylylylyl methyl cellulose (HPMC) Izindlela ze-solubity zinazo lezo?

- A: Indlela eshisayo yokuchithwa kwamanzi

1) Beka inani elidingekayo lamanzi ashisayo esitsheni bese usishisa cishe ku-70 ℃. Kancane kancane engeza i-hydroxypropyll methylcellulose ngaphansi kokuvuselelwa kancane, i-HPMC yaqala ukuntanta ebusweni bamanzi, bese kancane kancane yakha kancane kancane, ngaphansi komoya okuvuthayo kupholisa ama-slurry.

2), engeza inani elidingekayo lamanzi ayi-1/3 noma ama-2/3 esitsheni, bese ushisa ku-70 ℃, ngokusho kwendlela 1), ukuhlakazwa kwe-HPMC, ukulungiswa kwamanzi ashisayo athambile; Ngemuva kwalokho engeza inani elisele lamanzi abandayo kwi-slurry elishisayo, uvuse futhi upholise ingxube.

Indlela yokuxuba ye-powder: I-HPMC Powder kanye nenani elikhulu lezithako zezinto eziphithizelayo, ezixutshwe kahle ne-blender, ngemuva kokungezelwa amanzi, ngoba i-HPMC ngayinye, ngoba i-HPMC kuphela, i-HPMC kuphela, i-HPMC kuphela eshibilika ngokushesha. - Amabhizinisi okukhiqiza ama-Puterty namabhizinisi okukhiqiza ngodaka asebenzisa le ndlela. I-Hydroxypropylylylylylylyllls (HPMC) isetshenziswa njengomenzeli wokuqina kanye ne-ejenti yokugcina amanzi ePutty Powder Dater.

4, kulula futhi kunembile ukuthola ikhwalithi ye-hydroxypropyllylylylylylylylylylylylylylyl methyl cellulose (HPMC)?

- Impendulo: (1) IMhlophe: Yize ubumsulwa bungakwazi ukuthola ukuthi i-HPMC ilungele ukuyisebenzisa, futhi uma ingezwe kwinqubo yokukhiqiza ye-ejenti yamhlophe, izothinta ikhwalithi yayo. Kodwa-ke, imikhiqizo emihle imhlophe kakhulu.

.

. Ukugcwaliseka kwe-vertical reactor ngokuvamile kulungile, i-arlontal reactor imbi kakhulu, kepha ayikwazi ukukhombisa ukuthi ikhwalithi yokukhiqizwa okuqondile mpo ingcono kunalokho okukhiqizwayo kwe-reactor, ikhwalithi yomkhiqizo kunqunywa ngezinto eziningi.

. Kunokubaluleka, ngokujwayelekile ngoba okuqukethwe kwe-hydroxypropyl kuphezulu, okuqukethwe kwe-hydroxypropyl kuphezulu, khona-ke ukugcinwa kwamanzi kungcono.

I-5, i-hydroxypropyl methyl cellulose (HPMC) ngenani le-putty powder?

- Impendulo: I-HPMC ekusetshenzisweni kwangempela komthamo, ngesimo sezulu, izinga lokushisa, ikhwalithi ye-calcium ash yasendaweni, ifomula ye-putty powder kanye "nezidingo zamakhasimende zekhwalithi", futhi zihlukile. Ngokuvamile, phakathi kwamakhilogremu amane nanhlanu. Isibonelo: I-Beijing putty powder, ikakhulukazi faka ama-5 kg; EGuizhou, iningi lazo lingama-5 kg ​​ehlobo no-4,5 kg ebusika. Inani likaYunnan lincane, ngokuvamile ama-3 kg -4 kg nokunye.

I-6, i-hydroxypropyl methyl cellulose (HPMPC) ingakanani ukuhlakanipha okufanelekile?

- Impendulo: Yiba nesithukuthezi nge-general kampompi geker 100 Kulungile, imfuneko ku-motar is mude, funa amakhono ayizinkulungwane eziyi-150 okuwusebenzisa. Ngaphezu kwalokho, iqhaza elibaluleke kakhulu le-HPMC ukugcinwa kwamanzi, kulandelwa ukuqina. Ku-putty powder, inqobo nje uma ukugcinwa kwamanzi kulungile, i-viscosity iphansi (7-80,000), kungenzeka futhi, ukugcinwa kwamanzi kungcono, lapho i-viscosity ingaphezulu kwezinkulungwane eziyikhulu, lapho i-viscosity ingaba nomthelela omncane ekugcinweni kwamanzi.

7, I-Hydroxypropyl Methyl Cellulose (HPMC) Yiziphi izinkomba zobuchwepheshe eziphambili?

A: Okuqukethwe kwe-HYDROXYPROPYL kanye ne-viscosity, okuyilokho abaningi abakhathalelayo. Okuqukethwe kwe-Hydroxypropp kuphakeme, ukugcinwa kwamanzi ngokuvamile kungcono. I-Viscosity, Ukugcinwa kwamanzi, isihlobo (kodwa hhayi ngokuphelele) kungcono futhi, futhi i-viscosity, ku-cunmerman udaka kangcono.

I-8, i-hydroxypropyll methyl cellulose (HPMPC) izinto zokusetshenziswa eziphambili ezilukhuni yilokho?

- Impendulo: I-Hydroxypropyl Methyl Cellulose (HPMC) yezinto zokwenziwa eziphambili eziwukusebenzisana: Chloromethane, i-propylene oxide, ezinye izinto ezivuthiwe, i-a-acid, i-toluene, i-acid, i-toluene, i-isopropyl, njll.

9, HPMC ekusetshenzisweni kwe-Putty Powder, yini indima enkulu, noma i-chemistry?

I-HPMC ku-Putty Powder, ukuqina, ukugcinwa kwamanzi nokwakhiwa kwezindima ezintathu. Ukuqina Ukugcinwa kwamanzi: yenza i-putty powder eyomile kancane kancane, auxiliary ash calcium ukusabela ngaphansi kwesenzo samanzi. Ukwakhiwa: I-Cellulose inomphumela wokuthambisa, ingenza i-putty powder inokwakhiwa okuhle. I-HPMC ayihlanganyeli kunoma yikuphi ukusabela kwamakhemikhali, idlala indima ebalulekile kuphela. I-putty powder eyengeze amanzi, odongeni, ukusabela kwamakhemikhali, ngoba kukhona isizukulwane sezinto ezintsha, i-putty powder odongeni phansi odongeni, bese isetshenziswa, akusekho, ngoba yakha izinto ezintsha (i-calcium carbonate). Izingxenye eziphambili zeGrey Calcium Powder yilezi: CA (OH) 2, Cao kanye nenani elincane le-Capium Carbonate, i-CO2 REACH RECETION, eyakhe kuphela ukusabela kwamanzi, okwangempela akuzange kubambe iqhaza kunoma yikuphi ukusabela.

I-10, HPMC i-non-ionic cellulose ether, khona-ke yini okungeyona eye-ionic?

A: Ngokuvamile ukukhuluma, i-nonionic yinto emanzini angabi. I-Ionization yinqubo lapho i-electrolyte ihlukaniswe khona ngokuhamba ngama-ion athunyelwa ngokukhululekile kwi-solvent ethile, njengamanzi noma utshwala. Isibonelo, i-sodium chloride (i-NACL), usawoti esiwudlayo nsuku zonke, anciphise emanzini kanye nama-ionizes ukukhiqiza ama-sodium ions ashukumisayo ashukumisayo (NA +) akhokhiswa kahle nama-chloride ions (cl) akhokhiswa kabi. Ngamanye amagama, i-HPMC emanzini ayihlukaniswa ngama-ions amakhokho, kepha ikhona njengama-molecule.
