Yini i-viscosity efanele ye-hydroxypropyllm methylcellulose (HPMC)?
I-PuTTY SUCK imvamisa i-yuan eyi-100,000, futhi izidingo zodaka ziphezulu, kanti ezingama-150,000 yuan ziyadingeka ukuze zisetshenziswe kalula. 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.
Iziphi izindlela zokuchithwa kwe-hydroxypropylllylyllose (HPMC)?
. ( Kodwa-ke, iningi lemikhiqizo emihle limhlophe.
(2) Ubuchwepheshe: Ubumsulwa be-HPMC ngokuvamile bunama-80 mesh kanye ne-100 mesh, kanti ama-mesh ayi-120 awaphansi. Iningi le-HPMC elikhiqizwa eHebei liyi-80 mesh. Ubuciko obuhle, obukhuluma ngokuvamile, obungcono.
. Lapho kudlula khona ukudluliselwa kokukhanya, okungcono, okubonisa ukuthi kunezihlakala ezingaphansi kuyo. . Imvume yokuphendula okuqondile ngokuvamile ilungile, futhi lokho kuphendula okuvundlile kubi kakhulu, kepha akusho ukuthi ikhwalithi yokuphendula mpo ingcono kunaleyo yokuphendula okuvundlile, kanye nekhwalithi yomkhiqizo kunqunywa ngezinto eziningi. (4) Ukudonsela phansi okuthile: Kukhudlwana amandla adonsela phansi athile, okusindayo kube ngcono. Ukucaciswa kukhulu, ngokuvamile ngoba okuqukethwe kweHydroxypropyl Group kuyo kuphezulu, futhi okuqukethwe kweHydroxypropyl Group kuphezulu, ukugcinwa kwamanzi kungcono.
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.
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, isiza ukusabela okungcono kwe-Ash calcium, futhi akubandakanyi noma yikuphi ukusabela.
Ubudlelwano phakathi kokubonakala nokushisa kwe-HPMC, yini okufanele inake kuhlelo lokusebenza olusebenzayo?
I-viscosity ye-HPMC ilingana kakhulu namazinga okushisa, okungukuthi, i-viscosity inyuka njengoba izinga lokushisa lincipha. I-viscosity yomkhiqizo esivame ukubhekisa kuye ukuthi kubhekiswa kumphumela wokuhlolwa kwesisombululo sayo esingamanzi esingu-2% ekushiseni kwama-degree angama-20.
Kuzinhlelo zokusebenza ezisebenzayo, kufanele kuqashelwe ukuthi ezindaweni ezinemibono emikhulu yokushisa phakathi kwehlobo nobusika, kunconywa ukusebenzisa i-viscotive ephansi ebusika, evumelana kakhulu nokwakha. Ngaphandle kwalokho, lapho izinga lokushisa liphansi, ukubonakala kwe-cellulose kuzokwanda, futhi isandla sizizwa siba nzima lapho sikhahlela.
I-Viscosity Ephakathi: 75000-100000 ikakhulukazi isetshenziselwa ukubeka ama-putty
Isizathu: Ukugcinwa kwamanzi okuhle
I-Viscosity ephezulu: 150000-200000 isetshenziselwa ikakhulukazi i-polystyrerere incration inxangavishini yokufakwa kodubule kwerabha kanye nodumo oluvikelekile lwe-vitrify microbead.
Isizathu: Ukuvuleka okuphezulu, udaka akulula ukuwa, ukugcwala, okuthuthukisa ukwakhiwa.
