HEC bakeng sa liphahlo tse entsoeng ka metsi

tsebisa:

Lilemong tsa morao tjena, liphahlo tse thehiloeng metsing li tumme ka lebaka la botsoalle ba tsona ba tikoloho le litaba tse tlase tsa "volatile organic compound" (VOC). Motsoako o mong oa bohlokoa o bapalang karolo ea bohlokoa mekhoeng e sebetsang hantle ea ho roala ka metsing ke li-high-efficiency coalescent additives (HECs).

1. Utloisisa likhoele tse thehiloeng metsing:

A. Kakaretso ea ho koahela ka metsi

b. Melemo ea tikoloho ea liphahlo tse entsoeng ka metsi

C. Mathata a ho etsa liphahlo tse sebetsang hantle ka metsing

2. Kenyelletso ea li-additives tsa ho etsa lifilimi tse sebetsang hantle haholo (HEC):

A. Tlhaloso le litšobotsi tsa HEC

b. Tsoelo-pele ea histori le tsoelo-pele ea HEC

C. Bohlokoa ba ho kopana ha metsi a koahetsoeng ka metsi

3. Karolo ea HEC ts'ebetsong ea coalescence:

A. Coalescence le mekhoa ea ho theha lifilimi

b. Phello ea HEC holim'a coalescence ea likaroloana le botšepehi ba filimi

C. Ntlafatsa ho khomarela le ho tšoarella ka HEC

4. Lintlafatso tsa ts'ebetso ea HEC:

A. Ho thehoa ha filimi le nako ea ho omisa

b. Tšusumetso ho boemo le ponahalo

C. Phello ea ho thatafala le ho apara ho hanyetsa

5. Likarolo tsa ts'ebetso ea HEC ka liphahlo tse thehiloeng metsing:

A. Phokotso ea VOC le phello ea tikoloho

b. Tumellano ea taolo le maemo a lefats'e

C. Tlhahlobo ea potoloho ea bophelo ea liaparo tsa HEC tse thehiloeng metsing

6. Likopo tsa HEC liindastering tse fapaneng:

A. Mekhabiso ea Mehaho

b. Liaparo tsa likoloi

C. Liaparo tsa indasteri

d. Ho roala ka lehong

7. Mathata le tsoelopele ea nako e tlang:

A. Mathata a Hona Joale ho Tlhahiso ea HEC

b. Mekhoa e hlahang le mekhoa e mecha

C. Litebello tsa nako e tlang tsa HEC ka liphahlo tse entsoeng ka metsi

8. Lithuto le mehlala:

A. Tšebeliso e atlehileng ea HEC maemong a sebele

b. Tlhahlobo ea ho bapisa le li-additives tse ling tse etsang filimi

C. Lithuto Tse Ithutoang le Likhothaletso tsa Nts'etsopele

ha re phethela:

Ho akaretsa lintlha tsa bohlokoa tse tšohliloeng sehloohong sena, re totobatsa karolo ea bohlokoa ea HEC ho ntlafatsa ts'ebetso le ts'ebetso ea ho roala ha metsi. Monyetla oa ho tsoela pele ho etsa lipatlisiso le nts'etsopele sebakeng sena o totobalitsoe.
