HPMC (hydroxypropyl methylcellulose) ke tlatsetso ea bohlokoa e atisang ho sebelisoa linthong tsa mohaho tse kang putty powder, li-coatings, li-adhesives, joalo-joalo E na le mesebetsi e mengata e kang ho teteaneng, ho boloka metsi, le ts'ebetso e ntlafetseng ea kaho. Ha ho etsoa phofo ea putty, ho eketsoa ha HPMC ho ke ke ha ntlafatsa feela ho boloka metsi a sehlahisoa, empa hape ka katleho ho atolosa nako ea eona ea kaho, ho thibela putty hore e se ke ea omella ka potlako nakong ea kaho, 'me e ama phello ea kaho.
1. Khetha mofuta o nepahetseng oa HPMC
Ts'ebetso ea HPMC e amana haufi-ufi le boima ba eona ba molek'hule, hydroxypropyl substitution, methyl substitution le lintlha tse ling. E le ho ntlafatsa ho boloka metsi a putty powder, khetha pele mohlala o loketseng oa HPMC.
High viscosity HPMC: HPMC e nang le boima bo phahameng ba limolek'hule e ka etsa mohaho o matla oa marang-rang, o thusang ho ntlafatsa ho boloka metsi a putty powder le ho thibela ho fetoha ha metsi pele ho nako. Ka kakaretso, HPMC e nang le viscosity e phahameng e tla ba le phello e ntle ho matla a ho boloka metsi.
Tekanyo e nepahetseng ea ho nka sebaka: Phatlalatso ea hydroxypropyl le methyl substitution ea HPMC e ama matla a eona a ho qhibiliha le ho boloka metsi. Tekanyo e phahameng ea hydroxypropyl substitution e thusa ho ntlafatsa hydrophilicity ea HPMC, ka hona e ntlafatsa ts'ebetso ea eona ea ho boloka metsi.
Ho ea ka litlhoko tsa phofo ea putty, ho khetha mohlala o nepahetseng oa HPMC ho ka ntlafatsa haholo tekanyo ea ho boloka metsi ea sehlahisoa.
2. Eketsa palo ea HPMC e ekelitsoeng
E le ho ntlafatsa ho boloka metsi a putty powder, palo ea HPMC e ekelitsoeng e ka eketsoa ka mokhoa o nepahetseng. Ka ho eketsa karolo ea HPMC, kabo ea eona ka putty e ka ntlafatsoa ka nepo mme matla a eona a ho boloka metsi a ka ntlafatsoa.
Ho eketseha ha palo ea ho eketsoa ho tla boela ho lebise ho eketseha ha viscosity ea putty powder. Ka hona, hoa hlokahala ho etsa bonnete ba ho boloka metsi hantle ha o ntse o qoba viscosity e feteletseng ho ama ts'ebetso ea kaho.
3. Moralo oa foromo o utloahalang
Moralo oa foromo ea putty powder e ama ka kotloloho ho boloka metsi a eona. Ho phaella ho HPMC, khetho ea likarolo tse ling ka foromo (e kang li-fillers, li-adhesives, joalo-joalo) e tla boela e ama ho boloka metsi a putty powder.
Bokhabane le sebaka se itseng sa bokaholimo: Boholo ba phatsa le sebaka se itseng sa bokaholimo ba.filler in putty powder e tla ama ho ata ha metsi. Li-powders tse ntle le li-filler tse nang le sebaka se phahameng se ikhethileng li ka monya metsi hantle le ho fokotsa tahlehelo ea metsi. Ka hona, khetho e nepahetseng ea boholo ba karolo ea filler ke ntlha ea bohlokoa ho ntlafatseng ho boloka metsi.
Khetho ea metsoako ea samente: Haeba phofo ea putty e na le samente le lisebelisoa tse ling, karabelo ea hydration ea samente e ka ja metsi a mang. Ka hona, hoa hlokahala ho ntlafatsa ho boloka metsi a putty ka ho fetola karo-karolelano ea samente ho tlatsa.
4. Laola mokhoa oa ho kopanya
Mokhoa oa ho kopanya o boetse o na le phello e itseng ho boloka metsi a putty powder. Ho kopanya ho utloahalang ho ka thusa HPMC ho hasana ka botlalo le ho kopanya ka ho lekana le metsoako e meng ho qoba phapang ea ho boloka metsi e bakoang ke ho tsoakana ho sa tšoaneng.
Nako e loketseng ea ho kopanya le lebelo: Haeba nako ea ho kopanya e le khutšoanyane haholo, HPMC e ka 'na ea se ke ea qhibiliha ka ho feletseng, e leng se tla ama ts'ebetso ea eona ea ho boloka metsi. Haeba lebelo la ho kopanya le phahame haholo, moea o mongata o ka hlahisoa, o ama boleng ba putty powder. Ka hona, taolo e utloahalang ea mokhoa oa ho kopanya e tla thusa ho ntlafatsa ho boloka metsi ka kakaretso ea putty powder.
5. Laola mongobo oa tikoloho le mocheso
Ho boloka metsi a putty powder ha ho amane feela le lisebelisoa tse tala le foromo, empa hape ho amana haufi-ufi le mongobo le mocheso oa tikoloho ea kaho. Sebakeng se nang le mocheso o phahameng le mongobo o tlaase, mongobo oa putty powder o bonolo ho fetoha mouoane, o etsa hore o ome ka potlako le ho ama phello ea kaho.
Nakong ea ts'ebetso ea kaho, maemo a loketseng a mocheso le mongobo a lokela ho bolokoa ka hohle kamoo ho ka khonehang ho thibela phofo ea putty ho lahleheloa ke metsi ka potlako. Taolo e nepahetseng ea mocheso le mongobo le eona e ka ntlafatsa ka tsela e sa tobang ho boloka metsi a putty powder.
6. Eketsa moemeli oa ho boloka metsi
Ho phaella ho HPMC, mahlahana a mang a ho boloka metsi a ka boela a nkoa a eketsoa ho putty powder, joalo ka li-polymers tse itseng, joala ba polyvinyl, joalo-joalo Mahlahana ana a ho boloka metsi a ka ntlafatsa ho boloka metsi a putty, a eketsa nako ea kaho, 'me a thibela putty hore e se ke ea omella le ho phunyeha ka potlako haholo.
Leha ho le joalo, ha u eketsa lisebelisoa tse bolokang metsi, hoa hlokahala ho ela hloko ho lumellana ha bona le HPMC ho netefatsa hore ha ho na karabelo e mpe e hlahang kapa e amang ts'ebetso ea kaho ea putty.
7. Sebelisa theknoloji ea ho laola mongobo
Liketsahalong tse ling tse khethehileng, theknoloji ea ho laola mongobo e ka sebelisoa ho ntlafatsa ho boloka metsi a putty powder. Mohlala, ts'ebeliso ea li-membrane tsa ho tiisa tse thehiloeng metsing kapa lisebelisoa tsa humidification li ka fokotsa ka nepo tahlehelo ea metsi ea putty nakong ea kaho, ho boloka metsi a putty layer, ka hona ho lelefatsa nako ea eona ea kaho le ho ntlafatsa ho boloka metsi.
Ho boloka metsi a putty powder ho ka ntlafatsoa ka katleho ka ho khetha mofuta o nepahetseng oaHPMC, ho eketsa palo ea ho eketsa, ho ntlafatsa moralo, ho ntlafatsa mokhoa oa ho kopanya, ho laola mongobo le mocheso oa tikoloho ea kaho, le mehato e meng. E le karolo ea bohlokoa ea phofo ea putty, ntlafatso ea ho boloka metsi a HPMC e ke ke ea ntlafatsa feela ts'ebetso ea kaho, empa hape e ntlafatsa boleng ba ho qetela ba kaho le ho fokotsa mefokolo le mathata mohahong. Ka hona, ho utloisisa le ho tseba mekhoa ena ho ntlafatsa sekhahla sa ho boloka metsi ho bohlokoa haholo bakeng sa likhoebo tse hlahisang le ho sebelisa putty powder.
