tsebisa:
Li-cellulose ethers li sebelisoa haholo indastering ea kaho ka lebaka la ho boloka metsi a bona hantle, ho tiisa le ho kopanya thepa.Ba ntlafatsa phallo le ts'ebetso ea lisebelisoa tse thehiloeng ho samente le ho ntlafatsa thepa ea mochine ea sehlahisoa sa ho qetela.Li-putty li sebelisoa hangata indastering ea kaho ho tlatsa mapetsong, masoba le ho se phethahale ho hong maboteng le siling.Tšebeliso ea li-cellulose ethers ka li-putty powders li ka ntlafatsa ho sebetsa, ho beha nako le boleng ba kakaretso ba sehlahisoa.Sehlooho sena se tla tšohla phello ea li-viscosities tse fapaneng tsa cellulose ethers ho putty powder.
Mefuta ea li-cellulose ethers:
Ho na le mefuta e fapaneng ea li-cellulose ethers tse kenyeletsang methylcellulose (MC), hydroxypropylmethylcellulose (HPMC), ethylcellulose (EC) le carboxymethylcellulose (CMC).HPMC ke ether ea selulose e tsebahalang indastering ea kaho ka lebaka la ho boloka metsi hantle, ho tenya le thepa ea sekhomaretsi.HPMC e tla ka li-viscosity tse fapaneng, ho tloha tlase ho ea holimo.
Phello ea cellulose ether ho putty powder:
Putty phofo e sebelisetsoa ho tlatsa mapetsong, masoba le ho se phethahale ho hong ha marako le siling.Tšebeliso ea li-cellulose ethers ka li-putty powders li ka ntlafatsa ho sebetsa le ho beha nako ea sehlahisoa.Cellulose ether e ka boela ea ntlafatsa ho sebetsa le ho khomarela phofo ea putty.Se latelang ke phello ea li-viscosities tse fapaneng tsa cellulose ethers ho putty powder:
1. HPMC ea viscosity e tlase:
HPMC e tlaase ea viscosity e ka ntlafatsa metsi le ho sebetsa ha putty powder.E boetse e ntlafatsa nako ea ho beha sehlahisoa.Low-viscosity HPMC e na le mocheso o tlaase oa gelation, o ka thibelang phofo ea putty hore e se ke ea thatafala ka potlako.E ka boela ea ntlafatsa ho khomarela le ho kopana ha sehlahisoa.Low viscosity HPMC e loketse bakeng sa phofo ea putty e hlokang ho sebetsa hantle le ho boreleli.
2. Viscosity e mahareng HPMC:
Medium viscosity HPMC e ka ntlafatsa thepa ea thixotropic ea putty powder.E ka boela ea ntlafatsa ho boloka metsi le ts'ebetso ea tlamahano ea sehlahisoa.Medium-viscosity HPMC e ka ntlafatsa thepa ea mochini ea sehlahisoa, joalo ka matla le ho tšoarella.E loketse phofo ea putty e hlokang ho boloka metsi hantle le ho momahana.
3. High viscosity HPMC:
Viscosity e phahameng ea HPMC e ka ntlafatsa ts'ebetso e matla le e khahlanong le sag ea putty powder.E ka boela ea ntlafatsa ho boloka metsi le ts'ebetso ea tlamahano ea sehlahisoa.High viscosity HPMC e ka ntlafatsa thepa ea mochini ea sehlahisoa, joalo ka matla le ho tšoarella.E loketse phofo ea putty e hlokang ts'ebetso e matla le e khahlanong le sag.
ha re phethela:
Li-cellulose ethers li sebelisoa haholo indastering ea kaho ka lebaka la ho boloka metsi a bona hantle, ho tiisa le ho kopanya thepa.HPMC e fetohile ether ea cellulose e tsebahalang indastering ea kaho ka lebaka la thepa ea eona e ntle haholo.HPMC e tla ka li-viscosity tse fapaneng, ho tloha tlase ho ea holimo.Tšebeliso ea li-cellulose ethers tse nang le li-viscosities tse fapaneng li ka ntlafatsa ts'ebetso, ho beha nako, ts'ebetso ea thixotropic, ho boloka metsi, ts'ebetso ea bonding le thepa ea mechine ea putty powder.Tšebeliso ea li-cellulose ethers e ka ntlafatsa boleng le ts'ebetso ea li-putty powders, e leng se etsang hore li tšoanelehe bakeng sa likopo tse sa tšoaneng lefapheng la kaho.
