Astaamaha jireed iyo kiimikaad ee Fiber Alcohol Polyvinyl
Alaabooyinka taxanaha alkolada polyvinyl waa cadcad adag, muuqaalka flocculent, granular, budada saddex nooc; aan sun ahayn, ur lahayn, aan wasakhayn, waxaa lagu milmi karaa 80-90 ℃ biyo ah. Xalka aqueous wuxuu leeyahay adhesion wanaagsan iyo sifooyinka filimada; waxay u adkaysataa inta badan dareerayaasha organic sida saliidaha, saliidaha iyo hydrocarbons, iwm; waxay leedahay sifooyin kiimikaad sida esterification, etherification iyo acetalization of polyols silsilad dheer.

Fiber Alcohol Polyvinyl waa fir-fircooni sare, fiber modules oo ay soo saarto hannaan gaar ah oo loo isticmaalo alkolada polyvinyl sida walxo ceeriin ah. Waxay leedahay faa'iidooyinka xoogga sare, modules sare, elongation hooseeya, kala firidhsan wanaagsan, caabbinta acid iyo alkali, caabbinta abrasion, caabbinta UV iyo iska caabin daxalka. Waxa kale oo ay si fiican isugu darsataa sibidhka, sidaas darteed waxa loo isticmaali karaa noocyo kala duwan oo qalab xoojin ah. Hadda waxa si weyn loogu isticmaalaa biyo-xidheennada mashruuca ilaalinta biyaha, Korontada tamarta laga dhaliyo, qolalka dhulka hoostiisa ah, mashaariicda dekedaha, dhoobada shubka ah iyo goobo kale oo badan oo dhismo ah.

Polyvinyl Alcohol Fiber waxaa loogu talagalay modules sare, xoog sare, caabbinta alkali iyo aashitada, iyo caabbinta kulaylka. Sibidhka iyo walxaha kale ee polymer ayaa sidoo kale leh iswaafajin wanaagsan.

Macluumaadka shirkadda

Waxyaalaha ay shirkadu soo dejiso iyo wax-soo-saarka dhoofinta ugu badan waxaa ka mid ah

(1) Walxaha ceeriin organic : The alaabta ceeriin organic yihiin petrochemicals ka samaysan petroleum iyo gaaska dabiiciga ah, iyo warshadaha ee alaabta kiimikada organic kala duwan ayaa la soo saaray ama la jajabiyey by gaaska alaabta ceeriin ka dib gaasta dhuxusha iyo daamurka dhuxusha soo kabsaday by qallafsanaan qalalan.Our organic ceeriin Materials ka mid ah warshadaha ethylene, xeryahooda Ester, xeryahooda Ether.

(2) Dhexdhexaadiyaha : Dhexdhexaadiyeyaasha waa alaab-dhammeeyey, kuwaas oo ah alaabada dhexda u ah wax soo saarka alaabooyinka qaarkood, tusaale ahaan, si loo soo saaro badeecad, kaas oo laga soo saari karo dhexdhexaadiyeyaasha si loo badbaadiyo kharashka. Dhexdhexaadiyeyaasha ayaa laga heli karaa xeryahooda wareegga ah sida benzene, naphthalene, anthracene, iwm. Alaabooyinka waxaa ka mid ah dhexdhexaadiyeyaasha dawooyinka, dhexdhexaadiyeyaasha sunta cayayaanka iyo kuwa dhexdhexaadka ah.
