Ukusetshenziswa kwe-HPMC ku-Putty Powder

1. Yini i-viscosity efanele ye-HPMC?

- - Ngokuvamile, i-100,000 Yuan yanele i-putty powder. Izidingo zodaka ziphezulu, futhi i-150,000 Yuan iyadingeka ukusetshenziswa okulula. Ngaphezu kwalokho, umsebenzi obaluleke kakhulu we-HPMC ukugcinwa kwamanzi, kulandelwa ukuqina. Ku-putty powder, inqobo nje uma ukugcinwa kwamanzi kuhle futhi i-viscosity iphansi (70,000-80,000), kungenzeka futhi. Vele, ukukhuphuka okuphezulu, kungcono ukugcinwa kwamanzi okuhlobene. Lapho i-viscoty idlula i-100,000, i-viscosity izothinta ukugcinwa kwamanzi. Akusekho.

2. Yini izinkomba eziphambili zobuchwepheshe ze-HPMC?

- - Okuqukethwe kwe-Hydroxypropyl kanye nokubonakala, iningi labasebenzisi likhathazekile ngalezi zinkomba ezimbili. Labo abanokuqukethwe okuphezulu kwe-hydroxypropyl ngokuvamile banokugcinwa okungcono kwamanzi. Lowo onokuqonda okuphezulu unokugcinwa kwamanzi okungcono, ngokulinganayo (hhayi ngokuphelele), futhi lowo onamandla aphezulu asetshenziswa kangcono ngodaka kasimende.

3. Uyini umsebenzi oyinhloko wokusetshenziswa kwe-HPMC ku-Putty Powder, futhi kwenzeka ngamakhemikhali?

- - Ku-Putty Powder, i-HPMC idlala izindima ezintathu zokuqina, ukugcinwa kwamanzi nokwakha. Ukuqina Ukugcinwa kwamanzi: yenza i-putty powder eyomile kancane, futhi isize i-ash calcium ukuze usabele ngaphansi kwesenzo samanzi. Ukwakhiwa: I-Cellulose inomphumela wokuthambisa, okungenza i-Putty Powder ibe nokwakhiwa okuhle. I-HPMC ayihlanganyeli kunoma yikuphi ukusabela kwamakhemikhali, kepha idlala indima ebalulekile. Ukungeza amanzi ku-putty powder bese ukuwabeka odongeni ukusabela kwamakhemikhali, ngoba kwakhiwa izinto ezintsha. Uma ususa i-putty powder odongeni odongeni olusuka odongeni, ugaye lube yimpuphu, futhi uyisebenzise futhi, ngeke isebenze ngoba yenziwe izinto ezintsha (calcium carbonate). ) Futhi. Izici eziphambili ze-Ash Calcium Powder yilezi: Ingxube ye-CA (OH) 2, i-CAO + H2O / 2 + CO2 uqobo.

I-4. I-HPMC iyi-ether engeyona eye-cellulose, ngakho-ke yini okungeyona eye-ionic?

- - Kumagama we-layman, ama-non-ion ayizinto ezingeke ziveze emanzini. I-Ionization isho inqubo lapho i-electrolyte ihlukaniswe khona ngama-ion ashadiwe angahamba ngokukhululeka kwi-solvent ethile (njengamanzi, utshwala). Isibonelo, i-sodium chloride (i-NACL), usawoti esiwudlayo nsuku zonke, anciphise emanzini kanye nama-ionizes ukukhiqiza ngokukhululekile ama-sodium ion (NA +) akhokhiswa kahle nama-chloride ions (cl) akhokhiswa kabi. Lokho kusho ukuthi, lapho i-HPMC ibekwa emanzini, ngeke ihlukanise ama-ions amakhokho, kepha ikhona ngesimo sama-molecule.

5. Ngabe kukhona ubudlelwano phakathi kwethonsi le-putty powder ne-hpmc?

- - Ukulahleka kwempuphu ye-putty powder kuhlobene kakhulu nekhwalithi ye-Ash calcium, futhi kuncane ongakwenza nge-HPMC. Okuqukethwe okuphansi kwe-calcium ye-grey calcium kanye nesilinganiso esingafanele se-CAO ne-CA (oh) 2 in grey calcium izodala ukulahleka kwempuphu. Uma kunokuthile ongenziwa nge-HPMC, khona-ke ukugcinwa kwamanzi kwe-HPMC kumpofu, kuzodala nokulahleka kwempuphu

6. Ungayikhetha Kanjani i-HPMC efanelekile ngezinhloso ezihlukile?

- - Ukusetshenziswa kwe-Putty Powder: Izidingo ziphansi, futhi i-viscosity ingu-100,000, eyanele. Into ebalulekile ukugcina amanzi kahle. Ukusetshenziswa kodaka: izidingo eziphakeme, i-viscosity ephezulu, i-150,000 ingcono. Ukusetshenziswa kwe-glue: Imikhiqizo esheshayo enokubonakala okuphezulu iyadingeka.
