采用小麦淀粉进行精制，三聚磷酯钠进行磷酸酯化生产无碳复写纸 CB 涂料淀粉间隔基。试验结果表明：当氢氧化钙用量在0．3－0．4％时，蛋白质含量达到0．3％以下；当上层淀粉取样在70－80％时，粒径在15－25μm 范围的达65％左右，大于40μm 粒径小于1％，；当三聚磷酸钠的加入量为4％，尿素2％时其留着率可达0．8％以上。
採用小麥澱粉進行精製，三聚燐酯鈉進行燐痠酯化生產無碳複寫紙 CB 塗料澱粉間隔基。試驗結果錶明：噹氫氧化鈣用量在0．3－0．4％時，蛋白質含量達到0．3％以下；噹上層澱粉取樣在70－80％時，粒徑在15－25μm 範圍的達65％左右，大于40μm 粒徑小于1％，；噹三聚燐痠鈉的加入量為4％，尿素2％時其留著率可達0．8％以上。

The starch spacer in CB coating of NCR paper was made from refining wheat starch and phosphorylating sodium tripoly phosphate ester.Experiment shows that the protein content is below 0.3 % when the amount of calcium hydroxide is between 0.3% to 0.4 %;the content is about 65% for particles whose sizes are ranging from 15μm to 25μm,and less than 1% for those bigger than 40μm when the upper starch is sampled by 70 80 %;and the retention can be up to 0.8% when adding 4% sodium tripoly phosphate ester and 2% urea.
