Uzo Nlele Ogo nke ntụ ntụ polymer na-agbasa ọzọ

Nnwale dị mma nke polymer powders (RDPs) na-agbasasị na-agụnye ọtụtụ ụzọ iji hụ na arụmọrụ ha na nrube isi n'ụkpụrụ ụlọ ọrụ. Nke a bụ ụfọdụ ụzọ nnwale mma maka RDPs:

1. Nyocha nha urughuru:

  • Diffraction Laser: Na-atụ nkesa nha nha nke RDP site na iji usoro diffraction laser. Usoro a na-enye ozi gbasara nha urughuru nha, nkesa nha nha, yana n'ozuzu morphology urughuru.
  • Nyocha Sieve: Na-enyocha ụmụ irighiri ihe RDP site na usoro nha nha iji chọpụta oke nkesa. Usoro a bara uru maka ụmụ irighiri ihe mana ọ nwere ike ọ gaghị adabara ụmụ irighiri ihe dị mma.

2. Ntụpọ njupụta:

  • Na-ekpebi oke njupụta nke RDPs, nke bụ oke ntụ ntụ kwa otu olu. Nnukwu njupụta nwere ike imetụta ihe na-asọpụta, njikwa, na njirimara nchekwa nke ntụ ntụ.

3. Nyocha ọdịnaya mmiri mmiri:

  • Usoro gravimetric: A na-atụ ihe dị n'ime mmiri nke RDPs site na ihicha ihe nlele na tụọ mfu na oke. Usoro a na-enye ozi gbasara ọdịnaya mmiri, nke na-emetụta nkwụsi ike na nchekwa nke ntụ ntụ.
  • Karl Fischer Titration: Na-akọwapụta ọdịnaya mmiri dị na RDP site na iji Karl Fischer reagent, nke na-eji mmiri eme ihe kpọmkwem. Usoro a na-enye oke ziri ezi na nkenke maka mkpebi mmiri.

4. Ntụle okpomọkụ Transition (Tg):

  • Na-ekpebi ogo mgbanwe enyo nke RDP site na iji calorimetry nyocha dị iche (DSC). Tg na-egosipụta mgbanwe site na iko iko gaa na steeti rubbery ma na-emetụta arụmọrụ nke RDP na ngwa dị iche iche.

5. Nyocha ihe mejupụtara kemịkalụ:

  • FTIR Spectroscopy: Na-enyocha ihe mejupụtara kemịkalụ nke RDP site na ịlele nnabata nke radieshon infrared. Usoro a na-achọpụta otu ọrụ yana njikọ kemịkalụ dị na polymer.
  • Nyocha Elemental: Na-ekpebi ihe mejupụtara RDP site na iji usoro dị ka X-ray fluorescence (XRF) ma ọ bụ spectroscopy absorption spectroscopy (AAS). Usoro a na-akọwapụta mkpokọta ihe dị na ntụ ntụ.

6. Nnwale akụrụngwa nke igwe:

  • Nnwale tensile: Na-atụ ike ike, elongation na ezumike, yana modul nke ihe nkiri RDP ma ọ bụ mkpuchi. Usoro a na-enyocha ihe eji arụ ọrụ nke RDPs, nke dị mkpa maka ịrụ ọrụ ha na ngwa nrapado na ihe owuwu.

7. Nnwale gbasara ọmụmụ:

  • Ntụle viscosity: Na-ekpebi viscosity nke mgbasa RDP site na iji viscometers rotational ma ọ bụ rheometers. Usoro a na-enyocha omume eruba na njikwa njikwa nke mgbasa RDP na mmiri ma ọ bụ ihe mgbaze organic.

8. Nnwale adhesion:

  • Nnwale ike peel: Na-atụ ike nrapado nke nrapado dabere na RDP site n'itinye ike n'akụkụ ihe ntanetị mkpụrụ. Usoro a na-enyocha arụmọrụ njikọ nke RDP na mkpụrụ dị iche iche.

9. Nyocha nkwụsi ike nke thermal:

  • Thermogravimetric Analysis (TGA): Na-ekpebi nkwụsi ike nke okpomọkụ nke RDP site n'ịtụta ọnwụ dị arọ dị ka ọrụ nke okpomọkụ. Usoro a na-enyocha ọnọdụ okpomọkụ nke ire ere na omume mmebi okpomọkụ nke RDPs.

10. Nyocha ihe omimi:

  • Nyochaa Electron Microscope (SEM): Na-enyocha morphology na nhazi elu nke ụmụ irighiri ihe RDP na mmụba dị elu. Usoro a na-enye ozi zuru oke gbasara ọdịdị urughuru, oke nkesa, na ọdịdị elu.

Ụzọ nnwale ndị a dị mma na-enyere aka hụ na nkwekọ, ntụkwasị obi, na ịrụ ọrụ nke polymer powders (RDPs) na-emegharị na ngwa dị iche iche, gụnyere adhesives, mkpuchi, ihe owuwu, na usoro ọgwụ. Ndị na-emepụta ihe na-eji ngwakọta nke usoro ndị a iji chọpụta ihe anụ ahụ, kemịkalụ, igwe na ọkụ ọkụ nke RDPs wee chọpụta nrube isi na ụkpụrụ ụlọ ọrụ na nkọwapụta.
