Farqiga u dhexeeyabudada cinjirka ee dib loo cusboonaysiin karoiyo polyetylen glycol waa budada RDPwaxay leedahay sifooyin filim samaynta waxayna noqon karaan kuwo aan biyuhu lahayn, halka alkolada polyvinyl aysan lahayn. Khamriga polyvinyl ma bedeli karaa rdp wax soo saarka putty?
Qaar ka mid ah macaamiisha soo saara putty waxay isticmaalaan budada polymer dib loo cusboonaysiin karo, halka kuwa kalena ay isticmaalaan polyetylen glycol. Miyay ka wanaagsan tahay in loo isticmaalo budada cinjirka ah ama budada polyetylen glycol wax soo saarka Hadda, waxaan soo bandhigi doonaa farqiga u dhexeeya labada, si qof kastaa si fudud u go'aamiyo waxa loo isticmaalo wax soo saarka putty!
Budada cinjirka ee dib loo cusboonaysiin karo ayaa lagu farsameeyaalotion EVA oo tayo sare lehiyo buufin qalabka qalajinta. Alaabtu waxay leedahay dambas hooseeya, caddaan sare, dareere wanaagsan, aan sun ahayn iyo dhadhan la'aan, waxayna leedahay adhesion aad u fiican, hantida filim-samaynta wanaagsan iyo dabacsanaanta sare.
Polyethylene glycol sidoo kale waa budo cad oo leh heer gaar ah oo ku dheggan marka lagu milmo biyaha. Asal ahaan aad ugama duwana budada polymer dib loo firdhiyo. Farqiga ugu weyn ee u dhexeeya budada caagga ah iyo khamriga polyvinyl waa taasbudada cinjirka ee dib loo cusboonaysiin karowaxay leedahay hanti gaar ah oo filim samaynaysa, iyo sifooyinka samaynta filimada ee budada caagga ah laguma beddeli karo polyetylen glycol.
Faa'iidada budada polymer-ka ee dib loo cusboonaysiin karo ayaa ah in lagu daro inta lagu jiro wax soo saarka putty, iyo putty la soo saaray waxay leedahay heer gaar ah oo biyo-celin ah, oo aan lagu beddeli karin alaabooyin kale.
