Boemo ba glue ea kaho ke taba e khathatsang bareki.
1. Sehlopha sa sekhomaretsi sa kaho se lokela ho ela hloko lisebelisoa tse tala. Lebaka le ka sehloohong la ho thehoa ha lesela la tlamahano ke ho se lumellane pakeng tsa emulsion ea acrylic le hydroxypropyl methylcellulose (HPMC).
2. Ka lebaka la nako e sa lekaneng ea ho kopanya; sekhomaretsi sa kaho se boetse se na le bothata ba thepa e fokolang e teteaneng. Likhomaretsing tsa kaho, ho bohlokoa ho sebelisa kofi ea hang-hang hydroxypropyl methylcellulose (HPMC) hobane HPMC e qhalakane ka metsing mme ha e hlile ha e qhale. Kamora metsotso e ka bang 2, viscosity ea mokelikeli e eketseha butle, e hlahisa tharollo e hlakileng ea viscous colloidal. Lihlahisoa tse chesang tse chesang li ka hasana ka potlako metsing a belang 'me tsa nyamela metsing a belang ha li kopana le metsi a batang. Ha mocheso o theohela mocheso o itseng, ho fokotseha ha viscosity ho etsahala ho fihlela ho hlahisoa tharollo e hlakileng ea viscous colloidal. Ho khothaletsoa ka matla ho sebelisa 2-4 kg ea hydroxypropyl methylcellulose (HPMC) ho li-adhesives tsa kaho.
3. Lintho tsa 'mele tsa hydroxypropyl methylcellulose (HPMC) ho li-adhesives tsa kaho li tsitsitse, phello e khahlanong le hlobo e ntle haholo,' me e ke ke ea senngoa ke liphetoho tsa bohlokoa ba pH. Viscosity e ka sebelisoa pakeng tsa 100,000 s le 200,000 s, empa tlhahiso Ha ho etsoa tlhahiso, ho phahama ha viscosity, ho molemo. Viscosity e fapane ka tsela e fapaneng le matla a hatellang a sekhomaretsi. Ha viscosity e phahame, e fokotsa matla a khatello. Ka kakaretso, viscosity ke 100,000s.
Hona joale indastering ea mekhabiso, ts'ebeliso ea hydroxypropyl methylcellulose e thata haholo.

Hang-hang kopanya CMC le metsi ho etsa sekhomaretsi se kang sekhomaretsi 'me u behelle ka thōko. Ha u kenya pente ea CMC, sebelisa motsoako ho eketsa palo e itseng ea metsi a batang ho pitsa ea metsoako. Ha motsoako o qala, butle-butle u fafatse carboxymethylcellulose ka har'a tanka ea motsoako, 'me u tsoele pele ho susumetsa ho kopanya carboxymethylcellulose ka ho feletseng le metsi le ho qhala carboxymethylcellulose ka ho feletseng. Ha ho qhibiliha boto ea tube, hangata hoa hlokahala ho e hasanya ka mokhoa o ts'oanang le ho tsoela pele ho hlohlelletsa ho ntlafatsa "thibela ho thehoa le ho thehoa ha tubeboard ha e kopana le metsi, ho fokotsa bothata ba ho qhibiliha ha tubeboard" le ho ntlafatsa solubility ea tube board. . Sekhahla sa ho qhaloa ha komiti ea tsamaiso.
Nako ea ho kopanya e fapane le nako eo e e nkang hore CMC e qhalane ka ho feletseng. Tsena ke litlhaloso tse peli. Ka kakaretso, nako ea ho kopanya e khutšoanyane haholo ho feta nako ea ho felisoa ka ho feletseng ha CMC, ho itšetlehile ka boemo bo itseng. Nako ea ho kopanya e khethoa ho latela litekanyetso tsa data tse tsitsitseng. Ha CMC e hasane ka ho lekana ka metsing ntle le ho kopana ho totobetseng, ho kopanya ho felisoa ho lumella CMC le metsi ho phunyeletsana.
Ho na le mabaka a 'maloa a nako e hlokahalang ho qhala CMC ka botlalo:
(1) CMC le metsi li kopantsoe ka ho feletseng, 'me ha ho na thepa ea karohano ea metsi a tiileng pakeng tsa tsona;
(2) Motsoako o ts'oana ebile o boreleli, 'me bokaholimo bo boreleli ebile bo mongobo;
(3) Ka mor'a ho kopanya, pente ha e na mebala ebile e hlakile ka ho feletseng, 'me ha ho na likaroloana ho peista. Ho nka lihora tse 10 ho isa ho tse 20 ho tloha nakong eo CMC e kentsoeng ka har'a motsoako oa tanka ea metsoako le metsi ho fihlela e qhibiliha ka botlalo.
