Ho khetha thickener e nepahetseng bakeng sa ho hlatsoa 'mele ke habohlokoa bakeng sa ho finyella botsitso le ts'ebetso e lakatsehang.Thiener ha e ntlafatse mokhoa oa ho hlatsoa 'mele feela empa e boetse e tlatsetsa botsitso le ts'ebetsong ea eona.Ka mefuta e fapaneng ea li-thickeners tse fumanehang, e 'ngoe le e' ngoe e na le thepa ea eona e ikhethang le melemo, ho khetha e ntle ka ho fetisisa e ka ba phephetso.
1. Kenyelletso ho li-Thickening Agents:
Li-thickening agents ke lintho tse kenyellelitsoeng ho metsoako ho eketsa viscosity kapa botenya.
Li ntlafatsa sebopeho, botsitso, le ts'ebetso e akaretsang ea lihlahisoa tsa ho hlatsoa 'mele.
Li-thickeners tse fapaneng li fana ka maemo a fapaneng a viscosity, sebopeho le litšobotsi tsa kutlo.
2.Common Thickening Agents bakeng sa ho Hlatsoa 'Mele:
Li-surfactants: Li-surfactants ke lisebelisoa tse ka sehloohong tsa ho hloekisa 'mele, empa li ka boela tsa kenya letsoho ho hlahisa viscosity.Leha ho le joalo, li ka 'na tsa se ke tsa fana ka thickening e lekaneng ka botsona.
Li-Derivatives tsa Cellulose: Li-derivatives tsa cellulose tse kang hydroxyethyl cellulose (HEC), hydroxypropyl methylcellulose (HPMC), le carboxymethyl cellulose (CMC) li sebelisoa haholo li-thickeners mefuteng ea ho hlatsoa 'mele.Li fana ka thepa e ntle ea ho tenya 'me li lumellana le mefuta e mengata ea libopeho
Acrylate Copolymers: Acrylate copolymers, ho akarelletsa le Carbomer le Acrylates/C10-30 Alkyl Acrylate Crosspolymer, ke li-polymers tsa maiketsetso tse tsejoang ka bokhoni ba tsona ba ho tiisa.Li fana ka sebopeho se boreleli, se mabothobotho ho lihlahisoa tsa ho hlatsoa 'mele.
Guar Gum: Guar gum ke ntho ea tlhaho e teteaneng e tsoang ho linaoa tsa guar.E fana ka thepa e ntle ea ho tiisa le ho tsitsisa 'me e loketse ho etsa lihlahisoa tsa tlhaho kapa tsa tlhaho tsa ho hlatsoa' mele.
Xanthan Gum: Xanthan gum ke motenya o mong oa tlhaho o hlahisoang ke ho belisoa ha tsoekere ka baktheria ea Xanthomonas campestris.E fana ka viscosity le botsitso ho lihlahisoa tsa ho hlatsoa 'mele' me e ka ntlafatsa ho emisoa ha likaroloana ka har'a sehlahisoa.
Clays: Matsopa a kang letsopa la kaolin kapa letsopa la bentonite le lona le ka sebelisoa e le lisebelisoa tse teteaneng mefuteng ea ho hlatsoa 'mele.Li fana ka melemo e meng e kang ho phunya hamonate le ho tlosa chefo.
Li-Silicone Thickeners: Li-thickeners tse thehiloeng ho silicone tse kang Dimethicone Copolyol le Dimethicone li sebelisoa ho ntlafatsa sebopeho le boreleli ba lihlahisoa tsa ho hlatsoa 'mele.Li fana ka maikutlo a silika 'me li ka ntlafatsa thepa ea boemo ba letlalo.
3. Lintlha Tseo U Lokelang ho li Nahana ha U Khetha Thickener:
Ho lumellana: Netefatsa hore motenya o lumellana le lisebelisoa tse ling ha ho etsoa ho thibela litšebelisano tse sa rateheng kapa litaba tsa botsitso.
Viscosity: Nahana ka viscosity e lakatsehang ea ho hlatsoa 'mele' me u khethe motenya o ka finyellang botsitso bo lakatsehang.
Litšobotsi tsa kutlo: Lekola likarolo tsa kutlo tse joalo ka sebopeho, maikutlo, le chebahalo eo motenya o e fang ho hlatsoa 'mele.
Ho tsitsa: Lekola bokhoni ba setenya sa ho boloka botsitso ha nako e ntse e feta, ho kenyeletsoa ho hanyetsa liphetoho tsa mocheso, ho fapana ha pH, le tšilafalo ea likokoana-hloko.
Litšenyehelo: Nahana ka katleho ea litšenyehelo tsa "thickener" mabapi le tekanyetso ea kakaretso ea tlhahiso.
Tumellano ea Taolo: Netefatsa hore setenya se khethiloeng se lumellana le litlhoko tse nepahetseng tsa taolo le litekanyetso tsa polokeho bakeng sa lihlahisoa tsa litlolo.
4. Mekhoa ea ho Sebelisa:
Mekhoa e nepahetseng ea ho hasana le ea hydration ke ea bohlokoa bakeng sa ho fihlela ts'ebetso e nepahetseng ea ho teteana.
Latela litataiso tse khothalelitsoeng le litaelo tse fanoeng ke moetsi oa motenya bakeng sa ho kenyeletsoa ka katleho sebopehong.
5. Lithuto tsa Case:
Fana ka mehlala ea metsoako ea ho hlatsoa 'mele ho sebelisa mefuta e sa tšoaneng ea li-thickeners, ho totobatsa litšobotsi tsa bona tse khethehileng le melemo.
Kenyelletsa maikutlo a bareki le litekolo tsa ts'ebetso ho bonts'a katleho ea motenya ka mong lits'ebetsong tsa lefats'e la nnete.
Totobatsa karolo ea li-ajenti tse teteaneng ho ntlafatsa sebopeho, botsitso le ts'ebetso ea sehlahisoa ka kakaretso.
Khothaletsa lipatlisiso tse eketsehileng le liteko ho fumana setenya se setle ka ho fetisisa bakeng sa litlhoko tse khethehileng tsa tlhahiso.
ho khetha motenya o motle ka ho fetisisa bakeng sa ho hlatsoa 'mele ho kenyelletsa ho hlahloba ka hloko lintlha tse fapaneng tse kang ho lumellana, viscosity, litšobotsi tsa kutlo, botsitso, litšenyehelo, le ho lumellana le taolo.Ka ho utloisisa thepa le melemo ea li-thickeners tse fapaneng, baetsi ba lihlahisoa ba ka etsa lihlahisoa tsa ho hlatsoa 'mele tse fanang ka sebopeho se nepahetseng, ts'ebetso le khotsofalo ea bareki.
