1. Ke matšoao afe a mantlha a tekheniki a hydroxypropyl methyl cellulose (HPMC)?
HPMC Hydroxypropyl content le viscosity, basebelisi ba bangata ba amehile ka matšoao ana a mabeli.Ho boloka metsi ho molemo ho batho ba nang le hydroxypropyl e ngata.Viscosity e phahameng, ho boloka metsi, e batlang e le (ho e-na le ho feletseng) e molemo, le viscosity e phahameng, e sebelisoang hamolemo seretseng sa samente.
2. Mosebetsi oa mantlha oa ts'ebeliso ea HPMC ho putty ea lebota ke ofe?
Ka leboteng putty , HPMC e na le mesebetsi e meraro: thickening, ho boloka metsi le ho haha.
Thickening: Cellulose e ka teteaneng ho emisa le ho boloka seaparo sa tharollo, le ho hanela ho theoha.Ho boloka metsi: etsa hore lebota la putty le ome butle, 'me u thuse k'halsiamo e bohlooho ho itšoara tlas'a ketso ea metsi.Kaho: Cellulose e na le phello ea lubricating, e ka etsang hore putty ea lerako e be le ts'ebetso e ntle ea ho sebetsa.
3. Na lerotholi la lebota la putty le amana le HPMC?
Ho theoha ha lebota la putty ho amana haholo le boleng ba molora oa calcium, empa eseng ho HPMC.Haeba khalsiamo ea molora oa calcium le karo-karolelano ea CaO le Ca(OH)2 ka har'a molora calcium e sa nepahala, e tla baka tahlehelo ea phofo.Haeba e na le ho hong ho amanang le HPMC, ho boloka metsi ho futsanehile ha HPMC le hona ho tla baka lerotholi la phofo.
4. Hydroxypropyl methyl cellulose (HPMC) e bokae leboteng la putty?
Palo ea HPMC e sebelisoang lits'ebetsong tsa 'nete e fapana ho latela boemo ba leholimo, mocheso, boleng ba molora oa lehae oa calcium, foromo ea lebota la putty, le "boleng bo hlokoang ke bareki".Ka kakaretso, pakeng tsa 4 kg le 5 kg.Ka mohlala: Beijing wall putty ke boholo ba 5 kg;Hangata Guizhou e na le lik'hilograma tse 5 lehlabula le 4.5 kg mariha;Yunnan e batla e le nyane, hangata ke 3 kg ho isa ho 4 kg joalo-joalo.
5. Viscosity e nepahetseng ea hydroxypropyl methyl cellulose (HPMC) ke efe?
wall putty ka kakaretso ke 100,000 , empa seretse se batla ho feta, 'me ho nka 150,000 ho sebetsa.Ho feta moo, karolo ea bohlokoa ka ho fetisisa ea HPMC ke ho boloka metsi, ho lateloa ke ho teteaneng.Ka putty ea lerako , hafeela ho boloka metsi ho le molemo, viscosity e tlaase (70-80,000), hape hoa khoneha, ha e le hantle, viscosity e phahame, 'me ho boloka metsi ho lekanyelitsoeng ho molemo.Ha viscosity e feta 100,000, viscosity ha e na phello ea ho boloka metsi.
6. Joang ho khetha hydroxypropyl methylcellulose (HPMC) e nepahetseng bakeng sa merero e fapaneng?
Tšebeliso ea lebota la putty : tlhokahalo e tlase, viscosity ke 100,000, e lekane, ntho ea bohlokoa ke ho boloka metsi a le betere.Kopo ea seretse: litlhoko tse phahameng, viscosity e phahameng, e molemo ho feta 150,000, tšebeliso ea sekhomaretsi: lihlahisoa tse qhibilihang ka potlako, viscosity e phahameng.
7. Tšebeliso ea HPMC leboteng putty , ke eng e etsang hore lebota la putty le hlahise li-bubble?
HPMC e bapala likarolo tse tharo leboteng putty : thickening, ho boloka metsi le kaho.Se ke oa kenya letsoho karabelong efe kapa efe.Mabaka a li-bubble:
(1) Ho kenngoa metsi a mangata haholo.
(2) Lera le ka tlaase ha le omelle, ’me lera le leng le hohloa holim’a lona, leo le lona ho leng bonolo ho phophoma.
