I-Vissesity ephansi i-HPMC: I-HPMC 400 isetshenziselwa ikakhulukazi udaka oluzenzakalelayo, kepha ngokuvamile angeniswa.
Isizathu: I-visacosity iphansi, yize ukugcinwa kwamanzi kumpofu, kepha izinga lokulinganisa lihle, futhi ubuningi bukadaka buphakeme.
I-Viscosity Ephakathi nephansi:hydroxypropyl methylcelluloseI-HPMC 20000-40000 isetshenziselwa ikakhulukazi ukuthambekela okunamathela, umenzeli we-caulking, udaka lokulwa nokuqhekeka kwesibopho sokufakelwa okushisayo, njll.
Isizathu: Ukusetshenziswa okuhle, ukwengeza kwamanzi okuncane, ukuhlanganiswa okuphezulu kodaka.
1. Iyini inhloso esemqoka ye-hydroxypropyllyllose methylcellulose (HPMC)?
--A: I-HPMC isetshenziswa kabanzi ezintweni zokwakha, izimbobo, ama-desin zokwenziwa, ubumba - ubumba, umuthi, ukudla, izimonyo, ugwayi kanye nezinye izimboni. I-HPMC ingahlukaniswa ibe: Ibanga lokwakha, ibanga lokudla kanye nebanga lezemithi ngokwenhloso. Njengamanje, iningi lemikhiqizo yasekhaya ibangeni lokwakha. Ebangeni lokwakha, inani le-putty powder likhulu kakhulu, cishe ama-90% asetshenziselwa i-putty powder, futhi konke kusetshenziselwa udaka ngosimende neglue.
2. Kunezinhlobo eziningana ze-hydroxypropyll methylcellulose (HPMC), futhi yini umehluko ekusebenziseni kwabo?
--Swer: I-HPMC ingahlukaniswa ngohlobo olusheshayo nohlobo olushisayo olushisayo. Imikhiqizo yohlobo olusheshayo isabalala ngokushesha emanzini abandayo futhi inyamalala emanzini. Ngalesi sikhathi, uketshezi alunakubonakala, ngoba i-HPMC ihlakazeka emanzini kuphela futhi ayinakuchithwa kwangempela. Ngemuva kwemizuzu emi-2, i-viscosity yoketshezi inyuke kancane kancane, yakha i-colloid esobala ye-viscous. Imikhiqizo yokuqeda ukushisa, lapho ihlangabezana namanzi abandayo, ingahlakazeka ngokushesha emanzini ashisayo, futhi inyamalale emanzini ashisayo. Lapho amazinga okushisa ehla emazingeni okushisa athile (umkhiqizo wenkampani yethu ngu-65 degrees Celsius), i-viscosity ebonakala kancane kancane kuze kube yilapho yakha i-colloid esobala ye-viscous. Uhlobo olushisayo olushisayo lungasetshenziswa kuphela ku-putty powder nodaka. Ku-glue uketshezi kanye nopende, kwenzeke into ethambile futhi ngeke isetshenziswe. Uhlobo olusheshayo lunebanga elibanzi lezicelo. Ingasetshenziswa ku-putty powder nodaka, kanye ne-glue key upende, ngaphandle kokuphikiswa.
3. Iziphi izindlela zokuchithwa kwe-hydroxypropyllyllose methylcellulose (HPMC)?
- - Indlela eshisayo yokuchithwa kwamanzi Izindlela ezimbili ezijwayelekile zichazwa ngale ndlela elandelayo:
1) Beka inani elidingekayo lamanzi ashisayo esitsheni bese usishisa cishe ku-70 ° C. I-hydroxypropyllylylyl yangezwa kancane kancane ngokuvusa kancane, ekuqaleni i-hpmc entantayo ebusweni bamanzi, bese kancane kancane yakha kancane kancane, eyayipholile ngokuvusa ama-slurry.
2), engeza u-1/3 noma 2/3 wenani elidingekayo lamanzi esitsheni, bese usishisa ku-70 ° C, ngokwendlela ye-1), esabalalisa i-HPMC, lungiselela i-slurry yamanzi eshisayo; Ngemuva kwalokho engeza inani elisele lamanzi abandayo emanzini ashisayo ku-slurry, ingxube yehlisiwe ngemuva kokuvusa.
Indlela yokuxuba ye-powder: hlanganisa i-hpmc powder ngenani elikhulu lezinye izinto eziyimpuphu, bese wengeza amanzi ukuze uncibilike, ngoba i-HPMC encane ingachithwa ndawonye, ngoba kukhona i-HPMC encane kuphela ekhoneni elincane elincane. I-powder izoncibilika ngokushesha ukuxhumana namanzi. - - Indlela yasetshenziswa yi-putty powder kanye nabakhiqizi bakwaDitara. [I-Hydroxypropyl Methylcellulose (HPMC) isetshenziswa njenge-reatriner kanye ne-ejenti yokugcina amanzi ku-putty powder udaka. [Zosokhu
4. Ungahlulela kanjani ikhwalithi ye-hydroxypropyllykylm methylcellulose (HPMC) kalula futhi ngokuqondile?
- Kodwa-ke, iningi lemikhiqizo emihle limhlophe. . Iningi le-HPMC elikhiqizwa eHebei lingu-80 mesh. Ubuciko obuhle, okungcono. . Lapho kuphakama okudlulayo, okungcono, okubonisa ukuthi kunezinto ezingaphansi kokungaphansi kwalokho kuyo. Ukugcwaliseka kwe-reactoror mpo ngokuvamile kulungile, futhi i-reactor evundlile imbi kakhulu, kepha ayinakushiwo ukuthi ikhwalithi ye-reactoror mpo ingcono kunaleyo yokuphendula okuvundlile, futhi kunezinto eziningi ezinquma ikhwalithi yomkhiqizo. (4) Ukudonsela phansi okuthile: Kukhudlwana amandla adonsela phansi athile, okusindayo kube ngcono. Ukudonsela phansi okuthile kukhulu, ngokuvamile ngoba okuqukethwe kwe-hydroxypropyl kuyo kuphezulu, okuqukethwe kwe-hydroxypropyl kuphezulu, ukugcinwa kwamanzi kungcono.
I-5. Inani le-hydroxypropylll methylcellulose (hpmc) ku-putty powder?
- Inani le-HPMC elisetshenziswa ezinhlelweni ezingokoqobo liyahlukahluka ngokuya ngesimo sezulu, izinga lokushisa, ikhwalithi yendawo ye-ash calcium, ifomula ye-putty powder kanye "nekhwalithi edingwa amakhasimende". Ngokuvamile, kuphakathi kuka-4 kg no-5 kg. Isibonelo, iningi le-putty powder eBeijing lingu-5 kg; Iningi le-putty powder eGuizhou lingu-5 kg ehlobo kanye ne-4,5 kg ebusika;
6. Yini i-viscosity efanele ye-hydroxypropyllyllose methylcellulose (HPMC)?
- - I-putty powder ngokuvamile i-yuan ayi-100,000, futhi udaka lufuna kakhulu, futhi kulula ukulisebenzisa ku-150,000 yuan. Ngaphezu kwalokho, iqhaza elibaluleke kakhulu le-HPMC ukugcina amanzi, kulandelwe ukuqina. Ku-putty powder, inqobo nje uma ukugcinwa kwamanzi kuhle futhi i-viscosity iphansi (70,000-80,000), kungenzeka futhi. Vele, i-viscosity iphakeme, futhi ukugcinwa kwamanzi okuhlobene kungcono. Lapho i-viscosity idlula i-100,000, umphumela wokuvulelwa kokugcinwa kwamanzi akuyona into eningi.
7. Yiziphi izinkomba eziphambili zobuchwepheshe ze-hydroxypropyllyllose methylcellulose (HPMC)?
- - Okuqukethwe kwe-Hydroxypropyl kanye ne-viscosity, iningi labasebenzisi linakekela ngalezi zinkomba ezimbili. Okuqukethwe okuphezulu kwe-hydroxypropyl, okungcono ukugcinwa kwamanzi. I-viscosity ephezulu, ukugcinwa kwamanzi, okuningana (kunokuba ngokuphelele) okungcono, nokubonakala okuphezulu, ukusetshenziswa okungcono ku-cunmer udaka.
8. Yiziphi izinto eziphambili ezingavuthiwe ze-hydroxypropyllyllose methylcellulose (HPMC)?
- A: Izinto zokusetshenziswa eziphambili ze-hydroxypropylllyllose methylcellulose (HPMC): I-methyl chloride, i-propylene oxide, ezinye izinto ezingavuthiwe zifaka i-flake alkali, i-acid, i-toluene, i-isopropanol, njll.
9. Yini indima eyinhloko ye-HPMC ekusetshenzisweni kwe-Putty Powder, futhi ingabe kukhona ikhemikhali?
--Sanswer: I-HPMC inemisebenzi emithathu yokuqina, ukugcinwa kwamanzi nokwakha ku-putty powder. Ukuqina Ukugcinwa kwamanzi: yenza i-putty powder eyomile kancane, futhi isize ukusabela kwe-ash calcium ngaphansi kwesenzo samanzi. Ukwakhiwa: I-Cellulose inomphumela wokuthambisa, okungenza i-putty powder ibe nokusebenza okuhle. I-HPMC ayihlanganyeli kunoma yikuphi ukusabela kwamakhemikhali futhi idlala indima ebalulekile. Ukungeza amanzi ku-putty powder bese ukulubeka odongeni ukusabela kwamakhemikhali. Ngenxa yokwakheka kwezinto ezintsha, thatha i-putty powder odongeni oluphuma odongeni, uligaye lube yimpuphu, futhi uyisebenzise futhi. Ngeke kusebenze, ngoba kusungulwe izinto ezintsha (calcium carbonate). ) phezulu. Izakhi eziphambili ze-Ash Calcium Powder yilezi: Ingxube ye-CA (OH) 2, i-CAO kanye nenani elincane le-CACO3, i-CAO + H2O = CA (OH) 2 + CO2 = CALCIum Ngamanzi nomoya ngaphansi kwesenzo se-CO2, kukhiqizwa i-calcium carbonate, kuyilapho i-HPMC igcina kuphela amanzi futhi isiza ukusabela okungcono kwe-Ash calcium, futhi ayihlanganyeli kunoma yikuphi ukusabela ngokwakho.
10. I-HPMC ayiyona eye-ether engekho, ngakho-ke yini okungeyona eye-ionic?
- Impendulo: Ngamagama we-Layman, ama-non-ion ayizinto ezingasho lutho emanzini. I-Ionization isho inqubo lapho i-electrolyte ihlukaniswe khona ngama-ion athutha ama-sols ahambisanayo nge-solvent ethile (njengamanzi, utshwala). Isibonelo, i-sodium chloride (i-NACL), usawoti odliwe nsuku zonke, anciphise emanzini kanye nama-ionizes ukukhiqiza ngokukhululekile ama-sodium ion (na +) akhokhiswa kahle nama-chloride ions (cl) akhokhiswa kabi. Okungukuthi, lapho i-HPMC ibekwa emanzini, ayihlukaniswa ngama-ions ama-ions, kepha ikhona ngendlela yama-molecule.
