Uburyo Bwipimisha Bwiza bwa Re-Dispersible Polymer Powder

Uburyo Bwipimisha Bwiza bwa Re-Dispersible Polymer Powder

Igeragezwa ryiza rya pompe ya polymer (RDPs) ikubiyemo uburyo bwinshi bwo gukora neza no kubahiriza amahame yinganda. Hano hari uburyo busanzwe bwo gupima ubuziranenge bwa RDPs:

1. Ingano yubunini bwisesengura:

  • Gutandukanya Laser: Gupima ingano yubunini bwa RDPs ukoresheje tekinoroji yo gutandukanya laser. Ubu buryo butanga amakuru ajyanye nubunini bugereranije, ingano yikwirakwizwa, hamwe na morphologie muri rusange.
  • Isesengura rya Sieve: Yerekana ibice bya RDP binyuze murukurikirane rwubunini bwa mesh kugirango umenye ingano yikwirakwizwa. Ubu buryo ni ingirakamaro kubice bito ariko ntibishobora kuba byiza kubice byiza.

2. Igipimo kinini cy'ubucucike:

  • Kugena ubwinshi bwubwinshi bwa RDPs, nubunini bwa poro kumubumbe umwe. Ubwinshi bwinshi bushobora guhindura ibintu bitemba, gukora, hamwe nububiko bwa poro.

3. Isesengura ry'ibirungo:

  • Uburyo bwa Gravimetric: Gupima ubuhehere bwa RDPs ukama icyitegererezo no gupima igihombo mubwinshi. Ubu buryo butanga amakuru ajyanye nubushuhe, bugira ingaruka kumutekano no kubika ifu.
  • Karl Fischer Titration: Kugabanya ibirimo ubuhehere muri RDPs ukoresheje reagent ya Karl Fischer, ikora cyane cyane namazi. Ubu buryo butanga ibisobanuro nyabyo kandi byuzuye kugirango hamenyekane ubushuhe.

4. Isesengura ry'Ibirahure Ubushyuhe (Tg) Isesengura:

  • Kugena ubushyuhe bwikirahure bwa RDPs ukoresheje calorimetrie itandukanye (DSC). Tg yerekana inzibacyuho kuva mubirahuri ikajya kuri rubberi kandi ikagira ingaruka kumikorere ya RDPs mubikorwa bitandukanye.

5. Isesengura ryibigize imiti:

  • FTIR Spectroscopy: Isesengura imiterere yimiti ya RDPs mugupima kwinjiza imirasire yimirasire. Ubu buryo bugaragaza amatsinda akora hamwe nububiko bwimiti bugaragara muri polymer.
  • Isesengura ryibanze: Kugena ibice byibanze bya RDPs ukoresheje tekinike nka X-ray fluorescence (XRF) cyangwa atomic absorption spectroscopy (AAS). Ubu buryo bugereranya ubunini bwibintu biboneka muri poro.

6. Kugerageza Umutungo wa mashini:

  • Kwipimisha Tensile: Gupima imbaraga zingana, kurambura kuruhuka, hamwe na modulus ya firime ya RDP cyangwa ibifuniko. Ubu buryo busuzuma imiterere yubukorikori bwa RDPs, nibyingenzi mubikorwa byabo mubikorwa bifata kandi byubaka.

7. Ikizamini cya Rheologiya:

  • Igipimo cya Viscosity: Kugena ubwiza bwikwirakwizwa rya RDP ukoresheje viscometer cyangwa rotometero. Ubu buryo busuzuma imyitwarire yimikorere nuburyo bukemura ibiranga RDP ikwirakwizwa mumazi cyangwa ibishishwa kama.

8. Ikizamini cya Adhesion:

  • Ikizamini cya Peel Strength: Gupima imbaraga zifatika zifatika zishingiye kuri RDP ukoresheje imbaraga perpendicular kumurongo wa substrate. Ubu buryo busuzuma imikorere ya RDPs kuri substrate zitandukanye.

9. Isesengura rihamye ryubushyuhe:

  • Isesengura rya Thermogravimetric (TGA): Kugena ituze ryumuriro wa RDPs mugupima ibiro nkibikorwa byubushyuhe. Ubu buryo busuzuma ubushyuhe bwangirika hamwe nimyitwarire yo gutakaza ubushyuhe bwa RDPs.

10. Isesengura rya Microscopique:

  • Gusikana Electron Microscopy (SEM): Isuzuma morphologie nuburyo bwubuso bwibice bya RDP mugihe kinini. Ubu buryo butanga amakuru arambuye kubyerekeye imiterere y'ibice, gukwirakwiza ingano, hamwe na morfologiya yo hejuru.

Ubu buryo bwo gupima ubuziranenge bufasha kwemeza guhuza, kwizerwa, no gukora byongeye gutatanya ifu ya polymer (RDPs) mubikorwa bitandukanye, harimo ibifatika, ibifuniko, ibikoresho byubwubatsi, hamwe nubuvuzi bwa farumasi. Abahinguzi bakoresha uburyo bwubuhanga kugirango basuzume imiterere yumubiri, imiti, ubukanishi, nubushyuhe bwa RDPs no kugenzura niba byubahiriza ibipimo nganda nibisobanuro.
