Muraayad wanaagsan waxay u baahan tahay isku mid ahaansho,ka gudbiiyo cadayn. TWaa muraayadda ugu badan maanta waa natiijada sanadaha sahaminta.
| Horumarinta qalabka lenska Inta badan muraayadaha ugu horreeya waxaa lagu sameeyay gacanta loogu talagalay agabyada dabiiciga ah sida rubuc iyo isku-darka. Kobcinta wax soo saarka muraayadda iyo teknolojiyadda warshadaha, agabyada dabiiciga ah waxaa si dhakhso leh loogu beddelay galaas indhaha ah oo bilaabay inay bixiyaan howlo badan. Laga soo bilaabo 1960-yadii ilaa 1980-meeyadii, qalabka resin, oo laga sameeyay batroolka, waxay ku beddeleen dhalo si ay u helaan guryo indhaha ah, howlo aamin ah iyo astaamo jilicsan oo jir ahaaneed, oo noqdaan maaddada ugu weyn ee muraayadaha indhaha illaa hadda. |
Maaddaama sheyga ugu caansan muraayadda ee suuqa, agabyada resin waxaa inta badan matalaya resin cr-39 oo ay soo saartay PPG, Mr Resin oo uu soo saaray Mitsui,iyoKR Resin oo ay soo saartay KoC, Korea, iwm.
Qalabka lenska ayaa go'aamiya tusaha kala-soocidda ee muraayadda. Tilmaanta Lens Fikradda ah waa caadada xawaaraha faafinta iftiinka ee vacuum si uu xawaare u yahay khafiifka ah ee sheyga lenska, isagoo ka tarjumaya awoodda habboon ee muraayadda iftiinka. Guud ahaan marka la hadlayo, inta sare ee tilmaanta dib-u-noolaashaha ee muraayadda, lenska khafiifka ah.
