Motsoako oa motsoako oa metsi: Seretse se kopantsoeng ke mofuta oa samente, motsoako o motle, motsoako le metsi, 'me ho ea ka thepa ea likarolo tse fapaneng, ka tekanyo e itseng, ka mor'a ho lekanya seteisheneng sa ho kopanya, se kopantsoeng, se isoa sebakeng se sebelisoang ke teraka, ka har'a setshelo sa polokelo se inehetseng, 'me se sebelisoa ka nako e boletsoeng motsoako o felileng oa metsi.

Hydroxypropyl methyl cellulose e sebelisoa e le ntho e bolokang metsi bakeng sa seretse sa samente, ho pompa seretse sa retarder.Ka gypsum e le binder ho ntlafatsa kopo le ho eketsa nako ea ts'ebetso, hydroxypropyl methylcellulose HPMC ho boloka metsi e le hore slurry ka mor'a ho omisa e se ke ea e-ba ka potlako le ho senya, ho thatafatsa ho ntlafatsa matla.Ho boloka metsi ke thepa ea bohlokoa ea hydroxypropyl methyl cellulose HPMC, hape ke taba e tšoenyang bahlahisi ba bangata ba seretse se metsi.Lintlha tse amang phello ea ho boloka metsi ea seretse se metsi li kenyelletsa palo ea HPMC e ekelitsoeng, viscosity ea HPMC, botle ba likaroloana le mocheso oa tikoloho e sebelisoang.
Hydroxypropyl methyl cellulose HPMC karolong e ka sehloohong ea seretse se metsi likarolong tse tharo, e 'ngoe ke bokhoni bo botle ba ho tšoara metsi, ea bobeli ke ho lumellana ha seretse se metsi le thixotropy ea tšusumetso, ea boraro ke ho sebelisana le samente.Ho boloka metsi a cellulose ether ho ipapisitse le sekhahla sa ho monya metsi ha setsi, sebopeho sa seretse sa seretse, botenya ba seretse, tlhokahalo ea metsi a seretse, nako ea ho beha.Ha ponaletso ea hydroxypropyl methyl cellulose e phahame, ho boloka metsi ho betere.
Lintlha tse amang ho boloka metsi a seretse se metsi li kenyelletsa viscosity ea cellulose ether, ho eketsa palo, boholo ba likaroloana le mocheso.Ha ho na le viscosity e kholo ea cellulose ether, ho boloka metsi ho betere.Viscosity ke parameter ea bohlokoa bakeng sa ts'ebetso ea HPMC.Bakeng sa sehlahisoa se tšoanang, ho sebelisa mekhoa e fapaneng ea ho lekanya viscosity ea liphetho ho fapana haholo, tse ling esita le ka ntlha ea tse peli.Ka hona, papiso ea viscosity e tlameha ho etsoa ka mokhoa o ts'oanang oa tlhahlobo, ho kenyelletsa mocheso, rotor, jj.

Ha re bua ka kakaretso, ha viscosity e phahame, ho boloka metsi ho molemo.Leha ho le joalo, ha viscosity e phahame, boima ba limolek'hule ba HPMC bo phahame, 'me e theola ho qhibiliha ha HPMC, e nang le tšusumetso e mpe ho matla le ts'ebetso ea kaho ea seretse.Ha li-viscosity li phahame, ho hlakile haholoanyane phello e teteaneng ea seretse, empa ha e amane ka ho toba.Ha viscosity e phahame, seretse se metsi se khomarela haholoanyane, ts'ebetso e ntle ea kaho, ts'ebetso ea viscous scraper le ho khomarela holimo ho substrate.Leha ho le joalo, ntlafatso ea matla a sebopeho sa seretse se metsi ka boeona ha ea ka ea thusa.Kaho ea bobeli, ts'ebetso ha e totobetse khahlanong le ts'ebetso e leketlileng.Ka lehlakoreng le leng, li-viscosity tse ling tse mahareng le tse tlase empa hydroxypropyl methylcellulose e fetotsoeng e na le ts'ebetso e ntle haholo ho ntlafatsa matla a sebopeho sa seretse se metsi.
Ha palo e kholo ea cellulose ether PMC e eketsoa ka seretse se metsi, ho boloka metsi ho molemo, ho ba le viscosity e phahameng, ho boloka metsi ho molemo.Fineness hape ke index ea bohlokoa ea ts'ebetso ea hydroxypropyl methyl cellulose.
Botle ba hydroxypropyl methyl cellulose le bona bo na le tšusumetso e itseng ho bolokoeng ha eona ha metsi.Tlas'a maemo a tloaelehileng, viscosity e ts'oanang le botle bo fapaneng ba hydroxypropyl methyl cellulose, tlas'a tekanyo e lekanang ea ho phaella, ho fokotseha ho fokolang ha phello ea ho boloka metsi ho molemo.
Ka seretse se metsi, ho eketsoa ha selulose ether HPMC e tlase haholo, empa e ka ntlafatsa haholo ts'ebetso ea kaho ea seretse se metsi, ke tlatsetso e kholo e amang haholo ts'ebetso ea seretse.Ts'ebetso ea seretse se metsi e susumetsoa haholo ke khetho e nepahetseng ea hydroxypropyl methyl cellulose.
