Sidee loo kala soocaa muraayadda muraayadda iyo lenska resin?

1. Qalab cayriin oo kala duwan
Qalabka ugu muhiimsan ee muraayadda muraayadda waa muraayadda indhaha; Lens resin waa walxo dabiici ah oo leh qaab-dhismeedka silsiladda polymer-ka, kaas oo ku xidhan si uu u sameeyo qaab-dhismeedka shabakad saddex-cabbir ah. Qaab dhismeedka intermolecular waa mid dabacsan, waxaana jira meel bannaan oo u dhaxaysa silsiladaha molecular oo soo saari kara barokac qaraabo ah.

2. Adag oo kala duwan
Muraayadaha muraayadda, oo leh caabbinta xoqan oo ka badan qalabka kale, ma fududa in la xoqo; Qalafsanaanta dusha sare ee lenska resin ayaa ka hooseeya kan galaaska, waana sahlan tahay in lagu xoqo walxaha adag, sidaas darteed waxay u baahan tahay in la adkeeyo. Qalabka adagi waa silicon dioxide, laakiin adkaanta marnaba ma gaari karto adkaanta muraayadda, sidaas darteed qofka xiran waa inuu fiiro gaar ah u leeyahay ilaalinta muraayadda;

3. Tilmaanta refractive kala duwan
Tusmada dib-u-celinta ee muraayadaha muraayadda ayaa ka sarreeya muraayadda resinka, markaa isla darajada, muraayadda muraayadda ayaa ka khafiifsan muraayadda resinka. Muraayada muraayaddu waxay leedahay gudbin wanaagsan iyo sifooyin makaanochemical, index refractive joogto ah iyo sifooyin jidheed iyo kiimiko oo deggan.
Tusmada dib-u-celinta ee lenska resin waa dhexdhexaad. CR-39 propylene glycol carbonate ee caadiga ah waxay leedahay index refractive of 1.497-1.504. Waqtigan xaadirka ah, muraayadda resin-ka ee lagu iibiyo suuqa muraayadaha ayaa leh index ugu sarreeya, kaas oo gaari kara 1.67. Hadda, waxa jira lenses resin oo leh index refractive 1.74.

4. Kuwo kale
Waxyaabaha ugu muhiimsan ee muraayadda muraayadda ceeriin waa muraayadda indhaha. Tilmaanteeda dib-u-soo-celinta way ka sarraysaa muraayadda resin-ka, markaa muraayadda muraayadda ayaa ka khafiifsan muraayadda resin-ka oo isku mid ah. Muraayada muraayaddu waxay leedahay gudbin wanaagsan iyo sifooyin makaanochemical, index refractive joogto ah iyo sifooyin jidheed iyo kiimiko oo deggan. Muraayada aan midabka lahayn waxaa loo yaqaannaa cad cad (cad), lenska casaanka ah ee muraayadda midabka lehna waxaa lagu magacaabaa lens Croxel (cas). Lenses Croxel waxay nuugi karaan fallaadhaha ultraviolet waxayna nuugi karaan iftiin xoog leh.

Resin waa nooc ka mid ah karbokarbon (hydrocarbon) ee ka soo baxa dhirta kala duwan, gaar ahaan kuwa loo yaqaan conifers. Sababtoo ah qaab dhismeedka kiimikada gaarka ah oo loo isticmaali karo sida rinjiga cinjirka iyo koollada, waa la qiimeeyaa. Waa isku dhafka xeryahooda polymer-ka ee kala duwan, sidaas darteed waxay leedahay dhibco dhalaalid oo kala duwan. Xabagta waxa loo qaybin karaa xabagta dabiiciga ah iyo resin synthetic. Waxa jira noocyo badan oo resins ah, kuwaas oo si weyn loogu isticmaalo warshadaha fudud ee dadka iyo warshadaha culus. Waxa kale oo lagu arki karaa nolol maalmeedka, sida balaastigga, muraayadaha resinka, rinjiga, iwm
