Mokhoa oa ho etsa tharollo ea hec?

Hec (hydroxeeyl cemlolose

1. Boitokisetso
Pele u qala ho lokisa tharollo ea hec, etsa bonnete ba hore u lokiselitse lisebelisoa le lisebelisoa tse latelang:
Hec Powder (Litlhaloso tsa Mahala tse fumanehang haholo li na le limaraka tse fapaneng tsa Viscos, 'me sehlahisoa se loketseng se lokela ho khethoa ho latela kopo e khethehileng)
Solvent (hangata metsi a hloekileng a hloekileng, metsi a nang le metsi kapa li-solvent tse ling tse loketseng li sebelisoa)
Sesebelisoa se hlohlelletsa (khoereniki ea magnetic kapa mohloekisi)
Sesebelisoa sa moea sa mocheso (joalo ka ho hlapa ha metsi)
Setshelo (khalase kapa polasetiki e tsitsitseng e nang le molumo o lekaneng)
Tekanyo ea elektroniki

2. Mehato ea mantlha ea boitokisetso ba tharollo
2.1 Kgetha Solvent
Hec o na le sello hantle ka metsing, empa e le hore a ka thibela karohano kapa ho seha ho sa feleng nakong ea khefulo, taelo ea tlotla le ho hlomamile le taelo e lokela ho laoloa ka hloko. Metsi a imetsoeng hangata a sebelisoa e le ea solvent. Haeba ho hlokahala hore u lokise tharollo ea li-solvention system, u hloka ho khetha sistimi e loketseng ea solvent (joalo ka tsamaiso e tlisoang e kopantsoeng ea ethanol le metsi).

2.2 Ho futhumatsa metsi
Sekhahla sa disfototion sa hec se amana le mocheso oa metsi. Bakeng sa ho potlakisa ho felisoa ha Hec, metsi a futhumetseng (a ka bang 50 c) hangata a sebelisoa, empa eseng a phahame haholo ho qoba ho ama ts'ebetso ea hec. Sebelisa metsi a utloisoang ka sejaneng, qala ho futhumatsa, 'me u fetole mocheso o loketseng (40-50 ° C).

2.3 e hlohlelletsang ka mokhoa o tsitsitseng
Ha metsi a ntse a futhumatsa, qala ho hlohlelletsa. Sesebelisoa se susumetsang se ka ba sethala sa makenete kapa sebui sa mochini. Lebelo le itekanetseng le itekanetseng le lokela ho bolokoa ho qoba metsi a mangata ha u ntse u etsa hore u kopane le seaparo.

2.4 butle butle eketsa a hec phofo
Ha metsi a futhumatsoa ho 40-50 ° C, qala butle ho eketsa phofo ea hec. Ho qoba ho abelana ha phofo, e tlameha ho fafatsoa butle butle ha e ntse e hlohlelletsa. Mekhoa e latelang e ka sebelisoa ho ntlafatsa phetoho ea ho se hloekise:

Eketsa limeche: Se ke oa tšela kaofela ka nako e le 'ngoe, u ka eketsa liphefu tse ngata,' me u eme ho fihlela keketseho e tlang pele u eketsa nako e tlang pele u eketsa nako e tlang pele u eketsa nako e tlang pele.
Sive: Fafatsa phofo ea hec ka ho sheba ka metsing ho thusa ho fokotsa moferefere oa phofo.
Fetola lebelo la ho hlasimolla: Ha u foka phofo e matla, e kenang katolosong le ho hasanya limoleketso tsa limolek'hule tsa cellulose.

2.5 Tsoela pele ho hlohlona ho fihlela li qhibiliha ka botlalo
Khetho ea Hec ke ts'ebetso ea butle butle. Ha phofo e hasana ebile e felisitsoe, tharollo e tla hlaka butle-butle. Ho etsa bonnete ba hore hec e felisoa ka botlalo, lula u hlohlelletsa lihora tse ka bang 1-2, 'me nako e ikhethang e latela pono ea tharollo le palo ea Hec. Haeba likhopo li hlaha ka tharollo kapa tharollo ha e qhibiliha, nako ea ho susumetsoa e ka eketsoa hanyane kapa mocheso oa metsi o ka eketsoa hanyane ho feta 50 ° C.

2.6 Ho futhumatsa
Ha hec e felisoa ka botlalo, khaotsa ho futhumatsa le ho tsoela pele e hlohlelletsa, 'me tharollo e ile ea phonyoha mocheso ea kamore. Nakong ea bophelo bo pholileng, pono ea tharollo e ka tsoela pele ho eketseha ho fihlela e fihla boemong bo tsitsitseng.

3. Fetola khatello ea tharollo
Khatello ea tharollo ea Hec hangata e fetoloa ho latela sesebelisoa se itseng. Khetho e tloaelehileng ea hec e ratoang ke 0.5% ~ 5%, 'me boleng bo ikhethileng bo ikemiselitse ho latela phello e hlokahalang. Tse latelang ke mokhoa oa ho bala palo e hlokahalang ea

Hec:

Palo ea hec (g) = boholo ba tharollo (ml) × e hlokahalang (%)

Mohlala, haeba u hloka ho pheha 1000 tharollo ea 4% hec, o hloka 10g ea Hec Powder.

Haeba pono ea tharollo e phahame haholo kapa e tlase haholo ka mor'a ho itokisa, o ka e fetola ka mekhoa e latelang:

Thickening: Haeba pono e sa lekana, eketsa palo e nyane ea hec phofo. Ela hloko ho e eketsa ka libetsa tsa ho qoba ho belaela.

Bolo: Haeba pono ea tharollo e phahame haholo, eketsa metsi a sithabetsang ho le qoela ka nepo.

4. Phetoho ea tharollo
Ho netefatsa tharollo le bohloeki ba tharollo ea ho qetela, e ka ts'oaroa ka ho sitiha kapa pampiri ea filter. Fratranda e ka tlosa likaroloana tse sa sebetseng kapa lipelaelo, haholo-holo ho lits'ebetso tsa tlhophiso kapa litlolo).

5. Pholoso le polokelo
Tharollo ea hec e lokiselitsoeng e lokela ho tiisoa ho thibela ho qhekella le ho silafatsa. Ho khothalletsoa ho e boloka sebakeng se pholileng le se ommeng hole le khanya ea letsatsi. Haeba tharollo e bolokiloe nako e telele, tlhaselo ea likokoana-hloko e ka etsahala. Ho khothalletsoa ho eketsa batho ba bolokiloeng (joalo ka Phenoxetanol, Methylinoone, ETC.) Ha ho hlokahala.

6. Litemoso
Qoba Phatlalatso: Hec Powder Ho bonolo haholo ho fetoha ka metsing, haholo ha ho eketsa kapele kapa ho hlohlelletsa ha ho na thuso. Ho khothalletsoa ho sebelisa mokhoa oa ho kenyelletsa litle ka ho eketsa ka likepe le ho fetola lebelo le tsitsitseng ka nepo ho netefatsa hore phofo e qhalakakane.
Tekanyo ea Liphohelo: Haeba ho hlokahala, pono ea tharollo e ka lekanngoa ka ho sebelisa thepa joalo ka lifoto tse potolohileng ho etsa bonnete ba hore e etsa litlhoko tsa kopo.
Pholoso: Haeba tharollo ea hec e bolokiloe nako e telele, ho tlaloa ha peo e bolokiloeng ho qoba kholo ea likokoana-hloko ka tharollo le ho etsa tharollo ea ho senyeha.

Senotlolo sa ho etsa tharollo ea hec ke ho laola lebelo la mocheso, le matlafatsang le mokhoa o eketsehileng oa phofo ea Hec ho netefatsa hore likufu li ka qhibiliha. Agglometion e lokela ho thibeloa nakong ea ho felisoa ha pherekano, 'me boleng ba tharollo bo ka ntlafatsoa ka ho sefa ha ho hlokahala. Kamora ho ithuta mekhoa ena, o ka lokisa tharollo ea mafura a khotsofatsang litlhoko tsa hau mme o li sebelisetsa lihlahisoa tse fapaneng tsa indasteri le tsa letsatsi le letsatsi.
