Iyini i-viscosity efanele ye-hydroxypropyl methylcellulose (HPMC)?
I-putty powder ivamise ukuba ngu-100,000 yuan, futhi izidingo zodaka ziphezulu, futhi i-150,000 yuan iyadingeka ukuze isetshenziswe kalula. Ngaphezu kwalokho, umsebenzi obaluleke kakhulu we-HPMC ukugcinwa kwamanzi, okulandelwa ukujiya. Ku-putty powder, inqobo nje uma ukugcinwa kwamanzi kuhle futhi i-viscosity iphansi (70,000-80,000), kungenzeka futhi. Yiqiniso, ukuphakama kwe-viscosity, kungcono ukugcinwa kwamanzi okuhlobene. Lapho i-viscosity idlula i-100,000, i-viscosity izothinta ukugcinwa kwamanzi. Akusenani.
Yiziphi izindlela zokuchithwa kwe-hydroxypropyl methylcellulose (HPMC)?
(1) Ubumhlophe: Nakuba i-Baidu ingakwazi ukunquma ukuthi i-HPMC kulula yini ukuyisebenzisa, futhi uma ama-ejenti amhlophe engezwa phakathi nenqubo yokukhiqiza, ikhwalithi yayo izothinteka. Nokho, iningi lemikhiqizo emihle inobumhlophe obuhle.
(2) Ubuhle: Ubucwebe be-HPMC ngokuvamile buba ne-80 mesh kanye ne-100 mesh, kanye ne-120 mesh mincane. Iningi le-HPMC elikhiqizwe e-Hebei linezikhala ezingama-80. Ubuhle obuhle, uma sikhuluma nje, kuba ngcono.
(3) Ukudlulisa ukukhanya: faka i-hydroxypropyl methylcellulose (HPMC) emanzini ukuze wenze i-colloid ekhanyelayo, bese ubheka ukudlulisa ukukhanya kwayo. Ukudlulisa ukukhanya okukhulu, kungcono, okubonisa ukuthi kukhona okuncane okungancibiliki kuwo. . Ukufinyeleleka kwama-reactor aqondile ngokuvamile kuhle, futhi lokho kwama-reactor avundlile kubi kakhulu, kodwa akusho ukuthi ikhwalithi yama-reactor aqondile ingcono kunaleyo yama-reactor avundlile, futhi ikhwalithi yomkhiqizo inqunywa izici eziningi. (4) Amandla adonsela phansi athize: Uma umkhulu amandla adonsela phansi athile, uyasinda kakhulu. Ukucaciswa kukhulu, ngokuvamile ngenxa yokuthi okuqukethwe kweqembu le-hydroxypropyl kulo kuphezulu, futhi okuqukethwe kweqembu le-hydroxypropyl kuphezulu, ukugcinwa kwamanzi kungcono.
Imuphi umsebenzi oyinhloko wokusetshenziswa kwe-HPMC ku-putty powder, futhi ingabe kwenzeka ngamakhemikhali?
Ku-putty powder, i-HPMC idlala izindima ezintathu zokuqina, ukugcinwa kwamanzi kanye nokwakha.
Ukuqina: I-Cellulose ingajiywa ukuze imise futhi igcine umfaniswano wekhambi phezulu naphansi, futhi imelane nokuwohloka.
Ukugcinwa kwamanzi: yenza i-putty powder yome kancane, futhi usize i-calcium yomlotha ukuba isabele ngaphansi kwesenzo samanzi.
Ukwakhiwa: I-Cellulose inomphumela wokugcoba, ongenza i-putty powder ibe nokwakhiwa okuhle. I-HPMC ayibambi iqhaza kunoma yikuphi ukusabela kwamakhemikhali, kodwa idlala indima yokusiza kuphela. Ukwengeza amanzi ku-putty powder nokuyibeka odongeni ukusabela kwamakhemikhali, ngoba kwakhiwa izinto ezintsha. Uma ususa i-putty powder odongeni odongeni, uyigaye ibe yimpuphu, futhi uyisebenzise futhi, ngeke isebenze ngoba izinto ezintsha (i-calcium carbonate) zenziwe. ) futhi.
Izingxenye eziyinhloko zempushana ye-ash calcium yilezi: ingxube ye-Ca(OH)2, i-CaO nenani elincane le-CaCO3, i-CaO+H2O=Ca(OH)2 —Ca(OH)2+CO2=CaCO3↓+H2O ash calcium emanzini nasemoyeni Ngaphansi kwesenzo se-CO2, i-calcium carbonate ikhiqizwa, kuyilapho i-HPMC igcina amanzi kuphela, isiza ukusabela okungcono kwe-ash calcium, futhi ayihlanganyeli kunoma yikuphi ukusabela ngokwayo.
Ubudlelwano phakathi kwe-viscosity nezinga lokushisa le-HPMC, yini okufanele inakwe ekusebenzeni okusebenzayo?
I-viscosity ye-HPMC ihambisana ngokuphambene nezinga lokushisa, okungukuthi, i-viscosity iyanda njengoba izinga lokushisa liyancipha. I-viscosity yomkhiqizo esivame ukubhekisela kuwo ibhekisela kumphumela wokuhlolwa wesisombululo sawo samanzi esingu-2% ezingeni lokushisa elingu-20 degrees Celsius.
Ekusetshenzisweni okusebenzayo, kufanele kuqashelwe ukuthi ezindaweni ezinomehluko omkhulu wokushisa phakathi kwehlobo nobusika, kunconywa ukusebenzisa i-viscosity ephansi kakhulu ebusika, evumelana kakhulu nokwakhiwa. Uma kungenjalo, lapho izinga lokushisa liphansi, i-viscosity ye-cellulose izokhula, futhi ukuzwa kwesandla kuyoba nzima lapho kukhuhla.
I-viscosity ephakathi: 75000-100000 ikakhulukazi esetshenziselwa i-putty
Isizathu: ukugcinwa kahle kwamanzi
I-viscosity ephezulu: i-150000-200000 isetshenziselwa ikakhulukazi i-polystyrene particle insulation mortar rubber powder kanye ne-vitrified microbead insulation mortar.
Isizathu: i-viscosity ephezulu, udaka akulula ukuwa, ukugoqa, okuthuthukisa ukwakhiwa.
