Tšebeliso ea mantlha ea HPMC ke efe?
HPMC e ka aroloa ka: kereiti ea kaho, kereiti ea lijo le kereiti ea bongaka ka tšebeliso.
HPMC e sebelisoa haholo ka thepa ea moaho, likoahelo, li-resin tsa maiketsetso, lirafshoa, meriana, lijo, masela, temo, litlolo, koae le liindasteri tse ling.
Hona joale, boholo ba sehlopha sa kaho ea malapeng, sehlopheng sa kaho, tekanyo ea phofo ea putty e kholo, hoo e ka bang 90% e sebelisetsoa ho etsa phofo ea putty, e setseng e sebelisetsoa ho etsa seretse sa samente le sekhomaretsi.
Lisebelisoa tsa mantlha tsa HPMC ke life?
Lisebelisoa tsa mantlha tsa HPMC: k'hothone e hloekisitsoeng, chloromethane, propylene oxide. Lisebelisoa tse ling tse tala ke, letlapa la alkali, acid, toluene, isopropanol joalo-joalo.
- HPMC e arotsoe ka mefuta e mengata, phapang ea ts'ebeliso ke efe?
HPMC ka aroloa ka hang-hang le mocheso qhibilihang ka har'a mofuta.
Lihlahisoa tsa hang-hang, metsing a batang ka potlako li qhalakanngoa, li nyamela ka metsing, ka nako ena mokelikeli ha o na viscosity, hobane HPMC e qhalakantsoeng ka metsing, ha ho na ho qhibiliha ha sebele. Hoo e ka bang metsotso e 2, viscosity ea mokelikeli e ntse e eketseha butle-butle, e etsa "viscous colloid" e hlakileng. Ho ka sebelisoa mefuta e mengata ea li-putty powder le seretse, le sekhomaretsi sa metsi le pente, ha ho na taboo.
Lihlahisoa tse chesang tse qhibilihang, metsing a batang, li ka qhalakanngoa ka potlako metsing a chesang, li nyamela metsing a chesang, ha mocheso o theohela mocheso o itseng, butle-butle ho hlaha viscosity, ho fihlela ho thehoa ha colloid e hlakileng ea viscous. E ka sebelisoa feela ka phofo ea putty le seretse, ka sekhomaretsi sa metsi le pente, ho tla ba le ketsahalo ea sehlopha, e ke keng ea sebelisoa.
Litsupa tsa mantlha tsa tekheniki tsaHPMC?
Likahare tsa Hydroxypropyl le viscosity, basebelisi ba bangata ba amehile ka li-index tsena tse peli.
Likahare tsa Hydroxypropyl li phahame, ho boloka metsi ho molemo ka kakaretso.
Viscosity, ho boloka metsi, mong ka (empa eseng ka ho feletseng) e boetse e molemo, le viscosity, ka seretse sa samente molemo sebelisa ba bang.
Ke viscosity e kae e loketseng HPMC?
Karolo ea bohlokoa ka ho fetisisa ea HPMC ke ho boloka metsi, ho lateloa ke ho teteaneng.
Putty phofo ka kakaretso 100000 cps e ka ba. Hafeela ho boloka metsi ho le molemo, viscosity e tlaase (70,000-80000), hape hoa khoneha, ha e le hantle, viscosity e kholoanyane, ho boloka metsi a lekanyelitsoeng ho molemo, ha viscosity e feta 100,000, viscosity e na le phello e nyane ho boloka metsi.
Tlhokahalo ho MORTAR KE e telele ho feta, U BATLA KA KAKARETSO LINTHO TSE 150 hore u be molemo ho li sebelisa.
Kopo ea sekhomaretsi: hloka lihlahisoa tsa hang-hang, viscosity e phahameng.
