Teko ea boleng ba li-polymer powders tse qhaqhoang hape (RDPs) e kenyelletsa mekhoa e mengata ea ho netefatsa ts'ebetso ea bona le ho latela maemo a indasteri. Mona ke mekhoa e meng e tloaelehileng ea tlhahlobo ea boleng bakeng sa li-RDP:

1. Tlhahlobo ea Boholo ba Karolo:

• Phapang ea Laser: E lekanya kabo ea boholo ba likaroloana tsa li-RDP ho sebelisa mekhoa ea laser diffraction. Mokhoa ona o fana ka tlhahisoleseling mabapi le boholo ba likaroloana, kabo ea boholo ba likaroloana, le morphology ea likaroloana ka kakaretso.
• Sieve Analysis: E hlahisa likaroloana tsa RDP ka letoto la boholo ba marang-rang ho fumana hore na boholo ba karolo e ajoa joang. Mokhoa ona o na le thuso bakeng sa likaroloana tse mahoashe empa e ka 'na ea se ke ea tšoanela likaroloana tse ntle.

2. Kelo ea Boima ba Bongata:

• E etsa qeto ea bongata ba li-RDPs, e leng boima ba phofo ka tekanyo ea yuniti. Boima ba bongata bo ka ama thepa ea phallo, ho ts'oaroa le litšoaneleho tsa polokelo ea phofo.

3. Tlhahlobo ea Mongobo:

• Mokhoa oa Gravimetric: E lekanya boleng ba mongobo oa li-RDP ka ho omisa sampole le ho lekanya tahlehelo ka boima. Mokhoa ona o fana ka tlhahisoleseding mabapi le mongobo, o amang botsitso le ho boloka phofo.
• Karl Fischer Titration: E lekanya boleng ba mongobo ho li-RDP ka ho sebelisa reagent ea Karl Fischer, e sebetsanang le metsi ka ho khetheha. Mokhoa ona o fana ka ho nepahala ho phahameng le ho nepahala bakeng sa boikemisetso ba mongobo.

4. Tlhahlobo ea Khalase ea Phetoho ea Mocheso (Tg):

• E etsa qeto ea mocheso oa phetoho ea khalase ea li-RDP ka ho sebelisa differential scanning calorimetry (DSC). Tg e bonts'a phetoho ho tloha boemong ba khalase ho ea ho boemo ba rabara mme e susumetsa ts'ebetso ea li-RDP lits'ebetsong tse fapaneng.

5. Tlhahlobo ea Sebopeho sa Lik'hemik'hale:

• FTIR Spectroscopy: E sekaseka sebopeho sa lik'hemik'hale tsa RDPs ka ho lekanya ho monya ha mahlaseli a infrared. Mokhoa ona o khetholla lihlopha tse sebetsang le litlamo tsa lik'hemik'hale tse teng polymer.
• Elemental Analysis: E fumana sebopeho sa mantlha sa li-RDP ho sebelisoa mekhoa e kang X-ray fluorescence (XRF) kapa atomic absorption spectroscopy (AAS). Mokhoa ona o lekanya bongata ba likarolo tse teng ka phofo.

6. Teko ea Thepa ea Mechini:

• Teko ea Teko: E lekanya matla a tsitsitseng, bolelele nakong ea khefu, le modulus ea lifilimi tsa RDP kapa lijalo. Mokhoa ona o lekola thepa ea mochini ea li-RDP, tse bohlokoa bakeng sa ts'ebetso ea tsona lits'ebetsong tsa sekhomaretsi le tsa kaho.

7. Teko ea Rheological:

• Viscosity Measurement: E lekanyetsa viscosity ea li-dispersions tsa RDP ka ho sebelisa li-viscometer kapa li-rheometers. Mokhoa ona o lekola boitšoaro ba phallo le litšoaneleho tsa ho sebetsana le liphatlalatso tsa RDP ka metsing kapa ka lihlapolli tsa tlhaho.

8. Teko ea ho khomarela:

• Teko ea Matla a Peel: E lekanya matla a ho khomarela a li-adhesives tse thehiloeng ho RDP ka ho sebelisa matla a perpendicular ho substrate interface. Mokhoa ona o lekola tšebetso ea tlamo ea li-RDP ho li-substrates tse fapaneng.

9. Tlhahlobo ea Thermal Stability:

• Thermogravimetric Analysis (TGA): E khetholla botsitso ba mocheso oa li-RDP ka ho lekanya tahlehelo ea boima ba 'mele e le mosebetsi oa mocheso. Mokhoa ona o lekola mocheso oa ho bola le boitšoaro ba ho senyeha ha mocheso oa li-RDP.

10. Tlhahlobo ea Microscopic:

• Scanning Electron Microscopy (SEM): E hlahloba morphology le sebopeho sa bokaholimo ba likaroloana tsa RDP ka kholo e phahameng. Mokhoa ona o fana ka leseli le felletseng mabapi le sebopeho sa likaroloana, kabo ea boholo, le sebopeho sa bokaholimo.

Mekhoa ena ea tlhahlobo ea boleng e thusa ho netefatsa ho ts'epahala, ho ts'epahala le ts'ebetso ea li-polymer powders (RDPs) tse qhalakantsoeng hape lits'ebetsong tse fapaneng, ho kenyeletsoa likhomaretsi, liphahlo, lisebelisoa tsa kaho le litlolo tsa meriana. Baetsi ba sebelisa motsoako oa mekhoa ena ho lekola boleng ba 'mele, lik'hemik'hale, mochini le mocheso oa li-RDP le ho netefatsa hore li lumellana le litekanyetso le litlhaloso tsa indasteri.
