Nzira Yekuongorora Hunhu hwePolymer Powder Inopararirazve

Kuongororwa kwemhando yepamusoro kweupfu hwepolymer hunonyungudika (RDP) kwakakosha kuti uve nechokwadi chekuti hunosangana nezvinodiwa uye zvinodiwa pakushandiswa kwakasiyana-siyana, zvakaita sezvinhu zvekuvaka zvakaita sematiles, mamortar, uye mamembrane ekudzivirira mvura. Heano mamwe maitiro ekuongorora mhando yeupfu hwepolymer hunonyungudika zvakare:

1.Kuongororwa kweSaizi yeZvidimbu: Kugoverwa kwehukuru hwezvikamu kunokanganisa zvakananga mashandiro eRDP maererano nekupararira, kugadzirwa kwefirimu, uye hunhu hwemakanika. Matekiniki eLaser diffraction, sedimentation, kana microscopy anogona kushandiswa kuyera kugoverwa kwehukuru hwezvikamu zveRDP.

2.Kuwanda kwehuwandu: Kuwanda kwehuwandu hwezvinhu (bulk density) chinhu chakakosha chinokanganisa mashandiro, kutakurwa, uye kusanganiswa kweRDP. Kazhinji inoyerwa nekuzadza huwandu hunozivikanwa hweRDP mumudziyo uye kuyera huremu hwayo. Kuwanda kwehuwandu hwezvinhu (bulk density) kunozoverengerwa nekukamura huremu nehukuru.

3.Zviri Mukati Zvakasimba: Hunhu hwakasimba hweRDP hunoreva huwandu hwezvinhu zvakasimba zvepolymer muupfu. Hunowanzoonekwa nekuomesa huremu hunozivikanwa hweRDP patembiricha yakatarwa wobva wayera huremu hwasara. Hunhu hwakasimba hunoverengerwa zvichibva pakurasikirwa nehuremu panguva yekuomesa.

4.Kupisa Kwekuchinja kweGirazi (Tg): Tg yeRDP chiratidzo chekugadzikana kwayo mukupisa uye inokanganisa mamiriro ayo ekuchengetedza uye ekugadzirisa. Differential scanning calorimetry (DSC) kana dynamic mechanical analysis (DMA) zvinogona kushandiswa kuona Tg yeRDP.

5.Kupenya kweKupararira kweRDP: Kusimba kweRDP dispersion kwakakosha pakushandisa kwayo, zvakaita sekushanda zvakanaka, nguva yekuvhura, uye kuramba kudonha. Inogona kuyerwa uchishandisa viscometer kana rheometer pasi pemamiriro ekuchekwa kwesimbi akadzorwa.

6.Kuumbwa Kwemafirimu uye Kunamatira: Kugona kugadzira firimu uye simba rekunamatira reRDP zvakakosha pakushanda kwayo muzvinhu zvekuvaka. Nzira dzakadai sekuyedza kugadzira firimu, kuyedza kunamatira, uye kuyedza kusimba zvinogona kushandiswa kuongorora hunhu uhwu.

7.Kuongorora Kuumbwa Kwemakemikari: Matekiniki akadai seFourier-transform infrared spectroscopy (FTIR) kana nuclear magnetic resonance (NMR) spectroscopy anogona kushandiswa kuongorora makemikari eRDP uye kuona kuti inowirirana uye yakachena.

8.Kuedzwa kweKudzivirira Mvura: RDP inowanzo shandiswa mukushandiswa uko kudzivirira mvura kwakakosha, senge kudzivirira mvura. Kudzivirira mvura kunogona kuongororwa nekuita bvunzo dzakadai sekuongororwa kwekunyudzwa mumvura kana bvunzo dzekutapurirana kwemvura pazvinhu zvine RDP.

Idzi ndidzo dzimwe dzenzira dzinoshandiswa pakuongorora hunhu hwemhando yepamusoro pakugadzira upfu hwepolymer hunonyungudika zvakare. Zvichienderana nezvinodiwa pakushandiswa uye zviyero/mirau iripo, bvunzo dzekuwedzera dzinogona kudiwa kuti zvive nechokwadi chekuti zvigadzirwa zveRDP zvine hunhu uye mashandiro azvo.
