Budada Polymer-ka dib loo cusboonaysiin karo oo tayadeedu sareyso oo loogu talagalay isku darka Hoobiye

Hordhaca alaabta
Budada Polymer-ka dib loo cusboonaysiin karo ayaa iska leh nooc ka mid ah Dhexdhexaadiyeyaasha Dahaarka ah.
Waqtigan xaadirka ah, budada Polymer Redispersible ee adduunka oo dhan loo isticmaalo waa: vinyl acetate iyo ethylene copolymerization budada (VAC / E), ethylene iyo vinyl chloride iyo vinyl laurate terpolymerization budada (E / VC / VL), iyo vinyl acetate iyo vinyl iyo vinyl ester ee budada dufanka sare leh / VVemerization. waxay ku badan yihiin suuqa oo dhan, gaar ahaan vinyl acetate iyo ethylene copolymerization budada VAC/E, taas oo ah wax soo saarka hormuudka ah ee berrinka caalamiga ah oo ka dhigan sifooyinka farsamada ee budada cinjirka ee la firdhiyo. Budada copolymerization VAC/E, VAC/E, waa hogaamiyaha caalamiga ah ee goobta waxayna ka dhigan tahay sifooyinka farsamada ee budada polymer-ka ee la firdhi karo. Marka la eego khibradda farsamada ee polymers-ka lagu dabaqay wax ka beddelka hoobiye, weli waa xalka farsamada ugu fiican:
1.Mid ka mid ah polymers-ka ugu isticmaalka badan adduunka;
2. In uu leeyahay khibradda ugu badan ee qaybta dhismaha;
3.Waxa uu buuxin karaa sifooyinka rheological ee loo baahan yahay ee hoobiye (ie, shaqada loo baahan yahay);
4.Iyo monomers kale oo ah resin polymerization oo leh xeryahooda dabiiciga ah ee hooseeya (VOC) iyo sifooyinka gaaska xanaaqa hooseeya;
5.Iyadoo iska caabin UV aad u fiican iyo caabbinta kulaylka wanaagsan iyo sifooyinka xasilloonida muddada dheer;
6. Iyada oo iska caabin sare u leh guryaha saponification;
7.With kala duwanaanta heerkulka kala guurka galaas ugu ballaaran (Tg);
8.Iyadoo isku-dhafka wanaagsan ee isku-xidhka, dabacsanaanta iyo sifooyinka farsamada;
9.Iyadoo ugu dheer sida loo soo saaro alaab tayo leh oo deggan khibrad wax soo saarka kiimikada iyo ilaalinta xasilloonida kaydinta;

10. Aad u fudud iyo waxqabadka kolloid-ka ilaaliya (alkolada polyvinyl) oo la isku daray.

Samaynta budada polimer dib loo cusboonaysiin karo
Budada Polymer-ka dib loo cusboonaysiin karo badanaa waa budo cad, laakiin qaar ayaa leh midabyo kale. Qaybaha ay ka kooban tahay waxaa ka mid ah:
Polymer resin: waxa uu ku yaalaa qaybta xudunta u ah qaybaha budada ah, waana qaybta ugu muhiimsan ee budada Polymer-ka dib loo cusboonaysiin karo si ay kaalin uga qaadato.
Waxyaalaha lagu daro (gudaha): la shaqee xabagta si aad wax uga bedesho.
Waxyaalaha lagu daro (dibadda): Si loo sii balaadhiyo waxqabadka budada Polymer Redispersible oo lagu daro walxo kale.
Kolloid difaac ah: lakabka walxaha hydrophilic ee ku duudduuban dusha sare ee walxaha budada ah ee dib loo cusboonaysiin karo , inta badan kolloidka budada polymer dib loo cusboonaysiin karo waa alkolada polyvinyl.
Wakiilka-caking-ka-hortagga: buuxinta macdanta khafiifka ah, badiyaa loo isticmaalo si looga hortago in budada ay dubto inta lagu jiro kaydinta iyo gaadiidka iyo sidoo kale si loo fududeeyo socodka budada.

Macluumaadka shirkadda

Waxyaalaha ay shirkadu soo dajiso ama dhoofiso waxa ka mid ah

(1) Walxaha Ceyriin ee Organic: Waxay leedahay adeegsiyo ballaaran oo kala duwan, kuwaas oo loo qaybin karo saddex dhinac: marka hore, waxaa loo isticmaalaa sida alaabta ceeriin ee wax soo saarka kiimikada polymer, ie, monomers ee falcelinta polymerisation; labaad, waxa loo isticmaalaa sida alaabta ceeriin ee warshadaha kale ee kiimikaad organic, oo ay ku jiraan alaabta kiimikada wanaagsan; iyo saddexaad, waxa loo isticmaalaa sida dareere, qaboojiye, ka-hortag, iyo adsorbent gaas. Warshadaha kiimikada dabiiciga ah ee aasaasiga ah ayaa saldhig u ah horumarinta wax soo saarka alaabada kiimikada ee kala duwan, waa qaybta ugu muhiimsan ee qaabka casriga ah ee warshadaha casriga ah.

(2) Dhexdhexaadiyaha ： Dhexdhexaadintu waa badeecooyin semi-dhammeeyay, kuwaas oo ah alaabada dhexe ee wax soo saarka alaabooyinka qaarkood, tusaale ahaan, si loo soo saaro badeecad, taas oo laga soo saari karo dhexdhexaadiyeyaasha si loo badbaadiyo kharashka. Dhexdhexaadiyeyaasha ayaa laga heli karaa xeryahooda wareegga ah sida benzene, naphthalene, anthracene, iwm.
