Hydroxypropypropinyl MethylcelllOlolose (HPMC), joalo ka komporo ea polymer ea metsi, e sebelisoa hohle ntlafatsong ea thepa e thehiloeng ho baenjha. E le molaoli oa bohlokoa, e ka ntlafatsa boleng ba lisebelisoa tsa bohlokoa, haholo-holo tsa lik'hemik'hale, haholo-holo mabapi le ts'ebetso, ho ferekana le ho hloka botsitso ha thepa ea ho tiisa.
1. Ntlafatsa phokotsi ea thepa ea setifikeiti
Paste ea samente e hloka ho theoha hantle ha ho ahoa e le hore e ka tšolleloa ka selity ka mokhoa o hlollang. Kamora ho kenyelletsa hydroxypropyL methylcellilose, paseka ea samente e ka boloka phofu e ntle ka lebaka la eona phello e ntle ea eona e monate. Nakong ea Ts'ebeliso, HPMC e ka ntlafatsa phokotsi ka ho fetola pono ea paseka, e le hore paste e se e le nako ea ho sebetsa, e loketseng basebetsi ba kaho ho sebelisa thepa eo.
2. Ntlafatsa ho khomarela thepa
Ho ba le moea oa lisebelisoa tsa samente ho bohlokoa ho ea tšoarellang le ntlafatso ea matla. HPMC ke komporo ea polymer ea metsi ka bongata sebopeho sa hydrophphilic ka sebopeho sa lisele tsa maiketsetso le lifofane tsa samente le lifofane tse ka hlahang marang-rang. Tšusumetso ena e ke ke ea ntlafatsa feela ts'ebetso ea bona ea ho ba teng pakeng tsa samente le substrate, empa e boetse e hanyetsa thepa ea ho sebeletsa le ho ntlafatsa ho tiea le ho ntlafatsa phepo ea tsona. Boithuto bo bontšitse lintho tse thehiloeng ho letlobo ka katleho ea HPMC li ka fokolisa ho tloha ka nepo, ho itšepisa le ho lelekisa bophelo ba litaba.
3. Ntlafatsa ho se phethahale ha lisebelisoa tse thehiloeng ho mangolo
Ho se phethahale ha lisebelisoa tsa mahaeng ke e 'ngoe ea lisosa tsa bohlokoa tse amang ho tšoarella ha bona. Kenyelletso ea HPMC e ka ntlafatsa thepa ea lisebelisoa tsa samente, ka ho etsa sebopeho sa marang-rang, ka ho etsa joalo a fokotsa mofoka oa samente. Phokotso ea tšesatso e ntlafatsa ho se phethahale ha thepa ea ho hlophisa hangata. Boithuto bo bontšitse hore ho kenyelletsa palo e loketseng ea HPMC e ka thibelang lisebelisoa tsa ho sebelisa metsi ka nako e telele, li fokotsa ho nepahala ha meaho.
4. Ho lieha ho etsa mokhoa o hlakileng oa samente
Mokhoa oa bohloeki oa samente ke ts'ebetso e rarahaneng ea lik'hemik'hale. Ho hlahisa le kaho ea thepa e thehiloeng ho thibela bakang bakang bakang ka baka. Ho eketsoa ha HPMC ho ka liehisa ts'ebetso ea Hydration ea Felishene ea samente ka ho fetola pono ea ho nka karolo ea samente. HPMC e ka fetisa nako ea ho sebetsa le ho thibela paseka ea samente ho tiisa kapele. This feature is particularly suitable for cement-based materials that require long-term operation, which can improve the flexibility of construction and the operability of materials.
5. Ho ntlafatsa khanyetso ea mahala ea lisebelisoa tsa sistimi
Libakeng tse batang, lisebelisoa tsa thibelo hangata li pepesetsoa ho bataletse ha li -ycles, tse ka lebisang ho matla a lisebelisoa le tšenyo ea mekha. Ho eketsoa ha HPMC ho tsamaisa thepa ea saense ho thusa ho ntlafatsa khanyetso ea bona ea mahala. Ka ho fokotsa boima ba thepa ea samente, HPMC e ka fokotsa khatello ea metsi ha e batanyetsa lisebelisoa tse sa lefelloeng tsa sammente. Boithuto bo bontšitse hore palo ea HPMC e kentsoeng e loketse, ho ingolisa ha thepa ea sampt e ntlafalitsoeng haholo, libakeng tse bataletseng.
6. Ntlafatsa mocheso o phahameng oa mocheso oa lisebelisoa tsa center
Ha lisebelisoa tse thehiloeng ho saense li sebelisoa libakeng tse phahameng tsa mocheso, hangata ba tobana le mathata a kang ho hlasimolla le ho ts'oaroa ha 'mele. Ho eketsoa ha HPMC ho ka ntlafatsa mocheso o phahameng oa mocheso o hanyetsanang le thepa ea samente. Kaha HPMC e na le botsitso bo botle ba boqhetsi, bo ka boloka thepa ea botumo, ka tsela e phahameng, ka ho etsa joalo e khothaletsa matla le ho se ntlafatsa maemong a mocheso a mangata libakeng tse phahameng.
7. Pheta tšebetso ea kaho
Ts'ebetso ea kaho ke e 'ngoe ea mekhoa ea bohlokoa bakeng sa ho lekanya boleng ba thepa ea saense. HPMC e ka ntlafatsa haholo ts'ebetso ea lisebelisoa tsa samente le ho thibela mathata a kang ho aha le ho qala ha metsi nakong ea kaho. Ha o etsa kopo, lisebelisoa tsa semolao kapa tse tšollang thepa e amanang le ea HPMC e etsa hore thepa e be le eona e be le tlhompho le nako e bakoang ke thepa nakong ea kaho nakong ea kaho.
E le lisebelisoa tsa bohlokoa tse kenyelelitsoeng bakeng sa lisebelisoa tsa bohlokoa tse sebelisang lisebelisoa, hydroxypropy ea methylcelulese e ka ntlafatsa haholo thepa e fapaneng ea lisebelisoa. HPMC e bonts'a ts'ebetso e ntle ea lisebelisoa tsa ho ntlafatsa, ho futhumala, ho lieha ho ntlafatsa ts'ebetso ea kaho le ho hloka botsitso. Ka hona, mererong ea kaho ea khale, tšebeliso ea hydroxypropyly methylceluse e pharalletseng ebile e bapala karolo e ntle ho ntlafatsa ts'ebetso e felletseng ea thepa ea moaho.
