HEC ya zokutira zotengera madzi

dziwitsani:

M'zaka zaposachedwa, zokutira zokhala ndi madzi zadziwika bwino chifukwa chokonda zachilengedwe komanso zinthu zotsika kwambiri za organic organic compound (VOC). Chinthu chimodzi chofunikira kwambiri chomwe chimagwira ntchito kwambiri pakupangira zokutira zokhala ndi madzi ndikugwiritsa ntchito kwambiri ma coalescent additives (HECs).

1. Kumvetsetsa zokutira zotengera madzi:

A. Chidule cha zokutira zotengera madzi

b. Zopindulitsa zachilengedwe za zokutira zokhala ndi madzi

C. Zovuta popanga zokutira zamadzi zogwira ntchito kwambiri

2. Chiyambi cha zowonjezera mafilimu opanga mafilimu (HEC):

A. Tanthauzo ndi makhalidwe a HEC

b. Kukula kwa mbiri yakale ndi kusintha kwa HEC

C. Kufunika kwa coalescence mu zokutira madzi

3. Udindo wa HEC mu ndondomeko ya coalescence:

A. Coalescence ndi njira zopangira mafilimu

b. Zotsatira za HEC pa particle coalescence ndi kukhulupirika kwa filimu

C. Kupititsa patsogolo kumamatira ndi kulimba ndi HEC

4. Zowonjezera magwiridwe antchito a HEC:

A. Kupanga mafilimu ndi nthawi yowumitsa

b. Zokhudza kusanja ndi mawonekedwe

C. Zotsatira pa kuuma ndi kukana kuvala

5. Kukhazikika kwa HEC mu zokutira zokhala ndi madzi:

A. Kuchepetsa VOC ndi kukhudza chilengedwe

b. Kutsata malamulo ndi miyezo yapadziko lonse lapansi

C. Kusanthula kwa moyo wa HEC zokutira madzi

6. Ntchito za HEC m'mafakitale osiyanasiyana:

A. Zopaka Zomangamanga

b. Zovala zamagalimoto

C. zokutira mafakitale

d. Zovala zamatabwa

7. Mavuto ndi zomwe zidzachitike m'tsogolo:

A. Zovuta Zomwe Zilipo Panopa Kupanga kwa HEC

b. Zomwe zikuchitika komanso zatsopano

C. Chiyembekezo chamtsogolo cha HEC mu zokutira zokhala ndi madzi

8. Nkhani ndi zitsanzo:

A. Kugwiritsa ntchito bwino kwa HEC muzochitika zenizeni

b. Kusanthula kofananiza ndi zina zowonjezera zopanga mafilimu

C. Maphunziro Omwe Aphunziridwa ndi Malangizo Achitukuko

Pomaliza:

Kuti tifotokoze mwachidule mfundo zazikuluzikulu zomwe takambirana m'nkhaniyi, tikuwonetsa ntchito yofunika kwambiri ya HEC pakuwongolera magwiridwe antchito ndi kukhazikika kwa zokutira zam'madzi. Kuthekera kwa kafukufuku wowonjezereka ndi chitukuko m'derali kumawonekera.
