Inkonzo yasemva kwentengiso: Siza kulandela iziphumo zovavanyo zabathengi, kwaye ukuba kukho ingxaki, siza kuyikhangela kwindawo leyo.
Uvavanyo lwempahla eluhlaza
Ukuqinisekisa umgangatho weemveliso, senza uhlolo olungqongqo kwizinto zokwenza izinto, ngokwemigangatho yelizwe lase China.
Ukufumanisa i-resin ye-PVB powder
| iprojekthi | eguqukayo | viscosity osity 20 ℃ 10% / S） | Ubuninzi bokupakisha (g / ㎝3） | Isalathiso sokunyibilika elt 120 ℃ 21.6kg g / 10min) | Isidanga senkungu （%） | Ukuhambisa ukukhanya （%） | Ixabiso le-asidi （mgKOH / g) | Umxholo hydroxyl t Wt%） | Umxholo weqela leButyl t Wt%） | elubala |
Isampulu: emva kwayo yonke into eluhlaza ifike kumzi-mveliso, malunga neesampulu ze-5kg ziya kuthathwa kwilitha nganye.
Uvavanyo lwe-2.Appearance: mhlophe, intle kwaye ayikhululekanga nakuphi na ukungcola, umgubo ohamba ngokukhululekileyo okanye isuntswana.
3.Ukukhanya: thatha i-2kg yesampulu, yongeza i-1kg yeplastizerizer, xuba kakuhle, ukhuphe kwaye ubumbe inwebu, thelekisa umbala
4.Ukunyanzeleka: Nika ubunzima isampuli nge-analytical balance uze uyibeke kwibhotile enobunzima. Gcina ibhotile ehovini iiyure ezi-3, kunye nobushushu obungama-60 ℃ （± 1 ℃）. Emva kokuyikhupha, yibeke kwindawo eyomileyo imizuzu engama-20 ukuya kwengama-30 emva koko uyilinganise.
5.Viscosity: Yongeza i-resin powder kwi-funnel yamaphepha, faka ityhubhu yokugcoba kwi-65 bath yokuhlambela amanzi nge-1h, kwaye xa ikhutshwe kwaye ipholile kubushushu obungama-20 ℃ ± 1, galela isampuli kwikomityi yesikali , kwaye urekhode ixesha elahlileyo kwisisombululo ukufikelela kwi-50ml, eyi-viscosity yesampulu
Isalathiso se-Melt: Linganisa i-powder kunye ne-plasticizer (1: 3), ukongeza i-plasticizer kuqala kunye ne-powder kamva. Emva kokudibanisa kwisilinganiselo sokunyibilika kwesantya sokuhamba kwemitha, preheat imizuzu emi-4, yongeza ubunzima be-21.6g kwaye uqalise ukukhupha. Emva kwemizuzu emi-3, sika icandelo lokuqala, ulinde imizuzu emi-5 ngaphambi kokusika icandelo lesibini. Ubunzima obupheleleyo bamacandelo amabini buya kuba lixabiso lesalathiso sokunyibilika.
