Hydroxethyl cellulosese (Hec) ke moemeli ea fapaneng le o sebelisoang haholo o mongata oa pente le makhapetla. E phetha mesebetsi e mengata, e ntlafatsa ts'ebetso, botsitso le thepa ea lingoliloeng. Ka tlase ke tataiso e felletseng ea kamoo u ka sebelisang melemo ea bona ka bolokolohi ba lipere, e akaretsang melemo ea eona, e akaretsang.
Melemo ea Hydroyethyl cellulosese in Paints le Coatis
Metsoako ea Rheology: hec e fana ka phaello e lakatsehang le e lekang ho penta le bosholu, ba ba thusa ho jala le ho fokotsa ho ja.
Ntlafatso ea botsitso: E tiisa emulusion le ho thibela karohano ea karolo ea kholo, e netefatsa phetiso ea litakatso tsa mebala le lifilimi.
Lits'ebetso tse ntlafalitsoeng tsa kopo: Ka ho fetola pono, Hec e etsa hore ho be bonolo ho li sebelisa, ebang ke brashe, rollera, rollera kapa fafatsa.
Ho Boloka Metsi: Hec e na le thepa e ntle ea metsi a phomolo, e leng bohlokoa bakeng sa ho boloka ts'ebetso ea lintho tse bolotsana le likokoana-hloko maemong a omileng.
Ho lumellana: Hec e lumellana le mefuta e mengata ea li-solvelt, li-blomictive le li-blomitives tse ling, li etsa hore e be e loketseng liforomo tse fapaneng.
Mekhoa ea Kopo
1. Ho kopanya ho kopanya
Mokhoa o le mong o tloaelehileng ho kenyelletsa hec e ka tatellano ea pente e ka ho kopanya e omeletseng:
Mohato oa 1: Lekanya palo e hlokahalang ea phofo ea Hec.
Mohato oa Bobeli: Butle-butle eketsa phofo ea hec ho likarolo tse ling tse omelletseng tsa sebopeho.
Mohato oa 3: Ho netefatsa ho kopanya ka botlalo ho qoba ho choacing.
Mohato oa 4: Butle-butle eketsa metsi kapa ea sotlehileng ha a ntse a kopanya khafetsa ho fihlela hec e ntse e imetsoe ka botlalo le motsoako o mongobo o fihletsoe.
Ho kopanya ho omella ho loketse hore na lingaka li loketse moo ho laoloang lintho pele ho feta neng ho bolela hore lintho li hlokahala ho tloha qalong.
2. Litokisetso tsa Tharollo
Ho Lokisetsa tharollo ea setoko sa Hec pele ho eona ho kenyelletsa sebopeho sa pente ke mokhoa o mong o sebetsang:
Mohato oa 1: Qoba phofo ea Hec
Mohato oa Bobeli: Lumella nako e lekaneng ea hore Hec e kenelle ka botlalo ebile e qhibiliha, hangata lihora tse ngata kapa bosiu bo le bong.
Mohato oa 3: Kenya Tharollo ena ea setoko ho tsoa foromo ea pente ha u ntse u hlohlelletsa ho fihlela thepa e batlang le thepa eo e e fihletseng.
Mokhoa ona o lumella ho sebetsa le ho kenyelletsa hec, haholo-holo tlhahiso e kholo.
Sebopeho sa sebopeho sa sebopeho
1. Control
Khatello ea Hec e hlokoang ka foromo ea pente e fapana ho latela pono e lakatsehang le mokhoa oa kopo:
Likopo tse tlase: Bakeng sa brashi kapa suller kopo, khatello e tlase ea hec (0.2-1.0% ka boima) e ka lekana ho fihlela pono e hlokahalang.
Likopo tse phahameng: Bakeng sa lits'ebetso tse phahameng, tse phahameng haholo (1.0-2.0% ka boima) ho ka hlokahala hore a thibeloe.
2. Phetoho ea PH
PH ea foromo ea pente e ka ama qubu ea tuubility le ts'ebetso ea hec:
PH e nepahetseng: Hec e sebetsa hantle haholo ho se sa nke lehlakore ho feta Alkaline PH RO RAL (PH 7-9).
Phetoho: Haeba foromo ea ho theha acidic kapa alkaline haholo, lokisa pH u sebelisa litlatsetso tse loketseng joalo ka ammonia kapa arcic acits ho ntlafatsa ts'ebetso ea hec.
3. Mocheso
Mocheso o bapala karolo ea bohlokoa ho hydration le ho felisoa ha Hec:
Ho qhoma metsi a batang: Lihlahisoa tse ling tsa Hec li etselitsoe ho qhibiliha ka metsing a batang, a ka nolofatsa tšebetso e batang.
Ho potlakisa metsi a futhumetseng: Maemong a mang, u sebelisa metsi a futhumetseng a ka qojoa ts'ebetsong ea Helistera, empa mocheso o kaholimo ho 60 ° C o lokela ho qojoa ho thibela ho nyonyeha ha polymar.
4. Ho tsamaisana le lisebelisoa tse ling
Hec e hloka ho lumellana le lisebelisoa tse ling ho foromo ho qoba mathata joalo ka karohano ea gel kapa karohano ea pel.
Loelsts: hec e lumellana le lits'ebetso tse thehiloeng metsing tse thehiloeng metsing, empa tlhokomelo e lokela ho nkuoa ho netefatsa ho felisoa ka ho felletseng.
Likolobe le lifilimi: Hec e thusa ho tsitsisa malinyane le lipampiri, li bolela kabo ea sethoto le ho thibela ho lula.
Likhalase tse ling: Boteng ba ho senyeha, ho nyahama le litlatsetso tse ling li ka ama sebopeho le botsitso ba sebopeho sa hec se thebang.
Malebela a Sebetsang Bakeng sa Ts'ebeliso e Ntle
Khetho ea pele: Hec e nyahamisang pele u e kenyelletsa thetsong ea pente e ka thusa ho etsa hore ho ka tsamaisoa ka ho tsamaisoa le ho thibela ho khomarela.
Tlhahiso-leseling: Ha u eketsa hec ho theiloe, etsa hanyane ka hanyane le ho fella ka ho tsoela pele ho qoba likhopo.
Ho kopanya phahameng: Sebelisa bangoli ba phahameng ka bophara haeba ho khonahala, kaha ba ka thusa ho fihlela motsoako o motle le ho feta taolo.
TLHOKOMELISO E FEELANG: Fetola boemo ba Hec
Litaba tse tloaelehileng le ho rarolla mathata
Ho khopisa: Haeba hec e eketsoa kapele kapa ntle le ho kopanya, e ka theha likhomo. Ho thibela sena, ho lahla hec ka metsing butle-butle ha o ntse o hlohlelletsa ka matla.
Lilello tse sa lumellaneng: Ho fapana ka mocheso, PH, le ho kopanya lebelo ho ka baka pono e sa lumellaneng le bona. Kamehla hlokomela le ho lokisa lipalo tsena ho boloka lintho tse sa tsoatsoako.
Foaming: Hec a khona ho tsebisa moea ka sebopeho, o lebisang ho fofa. Sebelisa li-defoamer kapa li-agents tsa anti-bofokoli ho fokotsa taba ena.
Hydroxethyl Cebulosese ke karolo ea bohlokoa ka ho penta le e koahelang ka lebaka la bokhoni ba eona ba ho ntlafatsa liketsahalo, botsitso le thepa ea kopo. Ka ho utloisisa mekhoa e tsoetseng pele ea ho kenyelletsa HC, ho fana ka maemo a ho fetola litlhasi le ho rarolla mathata a tloaelehileng, le lihlahisoa tse nang le mekhoa e metle. Ebang ka ho kopanya e omisang kapa tharollo, thuto ea boithatelo e amanang le ho kopanya, PH le taolo ea mocheso le taolo ea mocheso ho phatlalatsa melemo ea bona ka botlalo.
