Waa maxay nooca filimka kulul ee koollada leh ee leh xoogga isku xidhka ee ugu xooggan?
Xabagta dhalaalaysa ee kulul waxaa loo aqoonsan yahay inay yihiin xabag deegaan ahaan u wanaagsan. Dabcan, alaabta filimka dhalaalaysa ee kulul ee laga sameeyay xabagta dhalaalaysa ee kulul ayaa sidoo kale deegaan ahaan u fiican. Tani waa sababta filimaanta kulul ee dhalaalka kulul ay u helayaan dareen badan maanta.

Filimka dhalaalka kulul ee kulul ayaa loo qaybin karaa noocyo badan iyadoo loo eegayo walxaha alaabta ceeriin. Kuwa ugu caansan waa filimka koollada kulul ee EVA, filimka koollada kulul ee TPU, filimka koollada kulul ee PA, filimka koollada kulul ee PES, iyo filimka koollada kulul ee PO. Noocyada, magacyada kiimikada u dhigma waa ethylene-vinyl acetate polymer, polyurethane thermoplastic, polyamide, polyester, polyolefin. Noocyada noocaan ah ee polymer-ka molecular waxay leeyihiin sifooyin u gaar ah, sidaas darteed waxqabadka alaabta filimka dhalaalaysa ee kulul ee la sameeyay ayaa sidoo kale ka duwan, laakiin sida badeecada dhejiska, tusaha waxqabadka ugu muhiimsan wuxuu noqon karaa xoogga isku-xidhka. Noocee ka mid ah alaabta filimka dhalaalaysa ee kulul ayaa leh xoogga ugu fiican?

Dhab ahaantii, ma jirto hab lagu bixiyo jawaab sax ah su'aasha ah xoojinta curaarta ayaa ugu fiican. Sababtoo ah noocyada kala duwan ee xabagta waxay leeyihiin sifooyin isku xirnaan oo kala duwan oo loogu talagalay qalabyo kala duwan, awoodaha isku xirnaanta ee ka muuqda sidoo kale way kala duwan yihiin. Tusaale ahaan, saamaynta isku-xidhka ee filimka koollada kulul ee PES ee birta guud ahaan wuu ka fiican yahay kan TPU filimka koollada kuleylka leh, laakiin nooc ka mid ah filimka koollada kulul ee TPU ayaa laga yaabaa inuu aad uga fiican yahay PES caagadaha. Sidaa darteed, su'aasha ah maaddada ugu fiican ee xoogga dhejiska ah maaha mid gaar ah oo adag in laga jawaabo. Guud ahaan, nooc gaar ah ayaa la bixin karaa ka hor inta aan la go'aamin iyada oo ku saleysan khibrad.

Dabcan, inta badan way adagtahay in si sax ah loo xukumo nooca filimka kulul ee kululeeyaha ah ee ugu fiican ee lagu xiro ka dib marka nooc gaar ah la bixiyo. Waxaan kaliya xukumi karnaa natiijada guud iyadoo lagu salaynayo xaalada ugu badan iyo waayo aragnimada. Xaqiijinta kama dambaysta ah waxay weli u baahan tahay tijaabooyin tijaabo ah si loo caddeeyo inay tahay tan ugu saxsan. Sababtoo ah xitaa haddii maaddadu ay isku mid tahay, farqiga u dhexeeya qallafsanaanta dusha sare, xiisadda dusha sare iyo arrimo kale ayaa ugu dambeyntii saameyn doona isku-xidhka walxaha sababtoo ah farqiga u dhexeeya habka.
