Hydroxypropypropypropinyl methylcelll. Mesebetsi ea eona ea mafilitsi e ntlafatsa likarolo tsohle tsa mekhoa e metle, ho thusa ho ntlafatsa ts'ebetso, ho boloka metsing le ts'ebetso ea ka kakaretso.
Seipo sa kaho sa kaho se ntse se batla tharollo ea metso e mecha ea ho ntlafatsa ts'ebetso le ho tšoarella ha thepa ea moaho. Har'a litlatsetso tse fapaneng tse sebelisoang ka har'a liforomo tsa lik'hemik'hale, Hydroxypropypropy MethylceLulo HPMC ke sesebelisoa sa cellulose se nang le thepa e ikhethang se ka amang meralo ea meralo le ho ntlafatsa mesebetsi e akaretsang ea kaho. Morero oa sengoliloeng sena ke ho hlahloba karolo le melemo ea HPM ea hodheshene ea HPM, ho kopanya sebopeho sa lik'hemik'hale, ho fana ka indastering ea kaho.
1. Lihlahisoa tsa lik'hemik'hale le thepa ea hpmc:
Hydroxypropypropypropinyl methylcelll E kenya letsoho ka ho phekoloa ke Cleulose le Methyl Cloride, e hlahisang motsoako o mong le methyl o hokahane le lihlopha tsa morao-rao tsa celd. Tekanyo ea sebaka (DS) ea hydropypropyl le lihlopha tsa methyl li khetha thepa ea HPMC, e kenyeletsang pono, sello sa motlakase.
HPMC e na le qubu e ntle ea metsi mme e etsa tharollo e pepeaneng le e hlahlojoang ha e hasoa ka metsing. Leha ho le joalo, liliba tsa eona li ipapisitse le mocheso, ka mocheso o phahameng o ratang ho felisoa. Thepa ena e etsa hore HPMC e loketse ho sebelisoa ka tatellano ea lik'heming tsa kaho moo lits'ebetso tse sebelisang metsi li atileng teng. Ntle le moo, HPMC e kenya boitšoaro ba PESUDlorts khafetsa ho fihlela tharollo, moelelo oo li o fokotsa le ho ntlafatsa ts'ebetso ea litlhare tse khomarelang.
2. Mechanism ea ketso ea ceramic ea Ceramic Tile:
Ka litlhahiso tsa likhoka tse khomaretsoeng, HPMC e sebetsa mesebetsi e fapaneng ka lebaka la sebopeho sa 'mele sa' mele se ikhethang le thepa. E 'ngoe ea mesebetsi ea eona e ka sehloohong ke ho sebetsa joaloka thickener, ho ntlafatsa tšebelisano le matla ha ad'ege. Ka ho eketsa litšoantšo, HPMC e thusa ho thibela seretse se khokhothetsoeng ho tloha ho sgengs kapa ho oela, ho netefatsa selikalikoe se pakeng tsa nile le tlatsetso.
HPMC e boetse e sebetsa joalo ka metsi a bolokang metsi, a lumella khathatso ea ho boloka li-mongole tse lekaneng nakong ea ho folisa. Thepa ena e bohlokoa ho netefatsa hydura e nepahetseng ea thepa e sa lekanyetsoang, e khothalletsang litlamo tse matla le ho fokotsa kotsi ea mapetso a shrinkage. Ho feta moo, bokhoni ba ho tšoara metsi ba HPMC bo thusa ho eketsa nako e bulehileng, ho lumella nako e lekaneng ea ho beha lithaba le ho hlophisoa pele ho imeloa.
HPMC e theha filimi e feto-fetohang le e thata ha o omisa, ka ho etsa joalo o ntlafatse thepa ea bona ea ho khomarela. Filimi e sebetsa e le ho khomarela pakeng tsa mochini o khabisang, lithaelese le substrate. Ho ba teng ha hpmc ho ntlafatsa matla a ka kakaretso le ho qoba ho kenya lithaelese, ho fokotsa menyetla ea ho hlakisoa kapa ho lieha ha nako.
3. Tšoereng tse ling tsa kaho ea kaho:
Ntle le lidolara tsa Tile, HPMC e sebelisoa haholo ho bapaloa ka mefuta e fapaneng ea kaho ea kaho ea lik'hemik'hale, ho kenyelletsa le litlolo, lijalo le ho thula. Mabaka a eona a tlhaho a e etsa a ekelletsa ho ntlafatsa ts'ebetso le ho tšoarella ha lisebelisoa tsena. Ka lefu, hpmc e sebetsa e le mosebeletsi oa Rheology, ho laola boitšoaro bo phallang le ho tsitsa tsa motsoako. Sena se tiisa kopo e ts'oanang le ho ntlafatsoa ho ntlafatsoe, ho tsamaisana le ho fokotsa litšila tsa lintho tse bonahalang.
HPMC e thusa ho ntlafatsa sebopeho sa ho iphahanya le setlamo le lipeo, ho lumella lefatše le boreleli. Bokhoni ba eona ba metsi bo thibela motsoako ka ho omella pele ho nako, bo khothalletsa ho thefula ka hohle le ho fokotsa ho se phethahale ka boka-lekaneng joalo ka mapetso kapa mapetso. Ntle le moo, HPMC e ntlafatsa hodhesion le ho khomarela lijalo le ho fanoa, li-grouts, li fella ka matla, li qeta haholo.
Ts'ebeliso ea HPMC ka li-amminami tsa kaho ea kaho li tsamaisana le lipakane tsa kaho tsa indasteri tsa kaho. Ka ho ntlafatsa ts'ebetso le ts'ebeliso ea lisebelisoa tsa ho fokotsa thepa, HPMC e kenya letsoho molemong oa lisebelisoa tsa matla le phokotso ea litšila. Ho feta moo, karolo ea eona ea ho ntlafatsa botebo ba thepa ea moaho e thusa ho phela ka lebaka la moaho, ka ho etsa joalo o fokotsa tlhoko ea litokiso kapa phetisetso ea khafetsa.
Hydroxypropypropinyl MethylceLulose (HPMC) e bapala karolo ea bohlokoa ho liprofikelong tsa sejoale-joale, ho fana ka melemo e fapaneng e thusang ho ntlafatsa ts'ebetso, ho ba le bokhoni le ho tšoarella. Sebopeho sa eona sa lik'hemik'hale se ikhethang sa lik'hemik'hale li thusa ho sebetsa joaloka thipa, metsi a bolokang agenner le adhesions li-ramona tse khokhothelang. Ntle le moo, HPMC e ntlafatsa thepa ea Rheoological ea ho kopana ha li-coupen tsa kaho ho nolofalletsa kopo le ho netefatsa hore sehlahisoa se felileng.
Tšebeliso ea HPMC ea HPMC ka har'a indastering ea kaho e totobatsa bohlokoa ba eona joaloka e 'ngoe ea lintho tse mpe e ntlafatsang boleng le ho tsitsisa thepa ea moaho. Joalokaha mekhoa ea kaho e ntse e tsoela pele ho fetola, tlhokahalo ea tharollo e meholo ea ho ntlafatsa ts'ebetso le kholo ea bongaka. Ka ho fokotsa bokhoni ba HPMC, indasteri ea molao e ka bonahala e tsoeloa ke ts'ebetso ea lintho tse bonahalang mme e kenya letsoho ntoeng ea tikoloho e tsitsitseng le e tsitsitseng.
