Nhasi suma muchidimbu zvinhu zvemuviri zvepurasitiki

1. Kufema
Kupinda kwemhepo kunocherechedzwa nekugonesa kwemhepo uye kufema kwemhepo coefficient.Kupinda kwemhepo kunoreva vhoriyamu (cubic metres) yefirimu repurasitiki rehumwe ukobvu pasi pekumanikidzwa mutsauko we 0.1 MPa uye nzvimbo ye 1 square mita (pasi pemamiriro akajairwa) mukati maawa makumi maviri nemana..Permeability coefficient huwandu hwegasi rinopfuura nepakati pepurasitiki firimu pachikamu cheyuniti uye ukobvu hweyuniti panguva yeyuniti uye unit pressure musiyano (pasi pemamiriro akajairwa).
2. Unyoro permeability
Kunyorova kwemvura kunoratidzwa nehuwandu hwemaonero uye maonero coefficient.Kupinda kwemwando ndiko kunyanya kuwanda (g) kwemhute yemvura inopinzwa nefirimu remamita mativi mana mumaawa makumi maviri nemana pasi pemamiriro eimwe mhute yekumanikidza mutsauko kumativi ese efirimu uye imwe firimu ukobvu.Maonero akaenzana huwandu hwemhute yemvura inopfuura nepakati pechikamu uye ukobvu hwefirimu muchikamu chenguva pasi pemusiyano wekumanikidza kweyuniti.
3. Kupinda kwemvura
Chiyero chekupinda kwemvura ndechekuona zvakananga kupenya kwemvura kweyedzo sampuli pasi pekuita kweimwe dzvinyiriro yemvura kweimwe nguva yenguva.
4. Kunwa mvura
Kunyura kwemvura kunoreva huwandu hwemvura inobatwa mushure mekunge imwe saizi yemuenzaniso yanyudzwa mune imwe dimension yemvura yakasvibiswa mushure menguva yakati.
5. Relative density uye density
Pane imwe tembiricha, reshiyo yehuremu hwesample kusvika kuhuwandu hwehuwandu hwemvura humwechete hunodaidzwa kuti hukama hwehukama.Huremu hwechinhu pavhoriyamu yeyuniti pane tembiricha yakatarwa inova density, uye unit ikg/m³, g/m³ kana g/mL.
6. Refractive index
Chiedza chinopinda mumhete yechipiri kubva pachikamu chekutanga ndeche (kunze kwekuitika kwakatwasuka).Sine yechero kona yechiitiko uye sine yekona yerefraction inonzi refractive index.Iyo refractive indekisi yepakati kazhinji yakakura kupfuura imwe, uye imwe svikiro ine akasiyana refractive indexes echiedza chewavelengths akasiyana.
7. Light transmittance
Kujeka kwemapurasitiki kunogona kuratidzwa nemwenje transmittance kana haze.
Kufambiswa kwechiedza kunoreva chikamu cheiyo inopenya inoyerera ichipfuura nepachena kana semi-pachena muviri kune chiitiko chayo chinopenya flux.Iyo mwenje transmittance inoshandiswa kuratidza pachena kwechinhu.Chiyero chinoshandiswa chiyero chizere chekuyeresa mwenje, senge yemba yekubatanidza sphere A-4 photometer.
Haze (Haze) inoreva kutaridzika kwemakore uye kubvongodzwa kwemukati kana pamusoro pemapurasitiki akajeka kana anopenya anokonzerwa nekupararira kwechiedza, anotaridzwa sechikamu chekuyerera kwechiedza chakapararira kumari uye mwenje unofambiswa.

8. Kubwinya
Kupenya kunoreva kugona kwepamusoro pechinhu kuratidza chiedza, chinotaridzwa sechikamu (percent) (gloss) yehuwandu hwechiedza chinotaridzwa kubva panzvimbo yakajairwa mune yakajairika ratidziro gwara remuenzaniso.
9. Moldshrinkage
Molding shrinkage inoreva huwandu hwehukuru hwechigadzirwa hudiki pane saizi ye mold cavity mm/mm
