YDN8080A Melamine-Formaldehyde Resin Stiffening Agent e Kentsoeng ka Metsi

Likarolo tsa Sehlahisoa

1. Ponahalo: Mokelikeli o hlakileng oa viscous;
2. Motsoako o sebetsang: 80.0 ± 0.2%;
3. pH: 8.0 - 10.0;
4. Viscosity (30 ° C): 800 - 1200cps;
5. Free formaldehyde (boima ba %): 0.4-0.6%;
6. Botsitso ba polokelo: E ka bolokoa likhoeli tse 3 sebakeng se phodileng le se nang le moea o pholileng, se ka hoamisoang;
7. Solubility: E ka qhibiliha ka metsing ka tekanyo leha e le efe, 'me e ka etsa li-colloid ka li-acid tse itseng;
8. Tšebelisano: E ka sebelisoa hammoho le lisebelisoa tse ngata tsa masela;
9. Bath botsitso: E tsitsitse lihora tse fetang 5 ka bateng.

Litšobotsi tsa Ts'ebetso

A) Masela a fiber a cellulose

Litšobotsi tse latelang li ka fumanoa ka ho sebelisa resin le YT hammoho ho sebetsana le lihlahisoa tse matla tsa cellulose:

1. Khanyetso e phahameng ea wrinkles le ho honyela, e tšoarella ebile e ka hlatsuoa;
2. Ts'ebetso e tšoarellang ea mochini ka mor'a ho hlatsoa;
3. Khatello e bakoang ke ho sebetsa ha resin e fokotsehile, 'me e na le khanyetso e ntle ea chlorine;
4. E eketsa lebelo la ho hlatsoa lidae tse ngata tse tobileng;
5. E matlafatsa ho hanyetsa hydrolysis e bakoang ke acid kapa ho lokolla lintho tsa acid;
6. Ha e fetole 'mala ka lebaka la phekolo ea mocheso;
7. Formaldehyde e tlase haholo e setseng holim'a lesela, e fokotsa haholo tloaelo ea sehlahisoa ho ba le monko oa formalin nakong ea polokelo ka mor'a ho sebetsa lesela;
8. Ha ho monko oa litlhapi.

B) Likhoele tsa maiketsetso

Resin e ka fana ka thepa e latelang bakeng sa NYLON, DACRON kapa likhoele tse ling tsa hydrophobic synthetic:

1. Boikutlo bo bonolo ba letsoho;
2. Boima bo loketseng le elasticity e phahameng;
3. E thibela metsi haholo ebile e thibela ho hloekisa;
4. Ha ho na ts'ebetso ea holim'a resin;
5. Ha ho monko nakong ea polokelo;
6. Ho fokotsa mathata a ho sebetsa ka mechine le tšilafalo.

Litaelo tsa ho Sebelisa

1. Maemo a masela: Lesela le tlameha ho hloeka 'me le se ke la ba le ntho leha e le efe e ka sitisang ho kenella ha resin, ts'ebetso e tloaelehileng le botsitso ba bateng, joalo ka asiti, alkali, letsoai kapa lintho tse ling.
2. Tokisetso ea ho hlapa: Ha ho na litemoso tse khethehileng kapa mekhoa ea ho lokisa bateng, kaha sehlahisoa sena se ka qhibiliha ka metsing ka tekanyo leha e le efe mocheso oa kamore.Khetho ea catalyst e itšetlehile ka thepa ea phekolo ea mocheso le mokhoa oa ho sebetsa;
3. Tšebelisano ea Catalyst: Li-Catalysts tse kang YT-01, YT-02, YT-03 li ka sebelisoa.
