Polymeization in diluents (such hexane) is the ealiest industialization and the most poductive method so fa.(2) liquid phe noumenon method. Polymeization in liquid popylene unde the condition of 70 C and 3MPa.(3) g phe method. Polymeization of popylene unde the condition of geous state. The latte two methods do not use diluent, the pocess is shot, and the enegy consumption is low. Liquid ontology method h shown the advantages of catch up fom behind.Molding chaacteist(1) physical poties: PP is a non-toxic, tteless and highly cystalline white polyme. It is one of the lightest vaieties of all plt, and is paticulaly stable fo wate. The wate absoption of 14h in wate is only 0.01%. The molecula weight is about 8~15 million, and its fomability is good. Howeve, because of the lage shinkage, the oiginal wall poducts ae ey to sag, the gloss of the poduct suface is good, and it is ey to colo.(2) mechanical poties: PP h high cystallinity and stuctue, so it h excellent mechanical poties, and its stength, hadness and elticity ae highe than that of high density PE (HDPE). The outstanding featue is ding fatigue esistance (7 * 10^7), opening and closing, ding and ding without damage tace, dy fiction coefficient is simila to nylon, but it is not good nylon when oil is lubicated.(3) themal fomance: PP h good heat esistance, the melting point is at 164~170 C, and the poduct can be steilized at the tematue above 100 degees C. Unde the action of extenal foce, it is not defomed at 150. The embittlement is -35 C, and the bittleness will occu at lowe than -35 C, and the heat esistance is not good PE.EMA In ecent yeas, the household electical appliance industy in China h developed apidly, with many vaieties and lage output. In 2003, thee wee 18 million 500 thousand efigeatos in ou county, 42 million ai conditiones, 17 million whing machines and 35 million micowave ovens. Accoding to the eseach consultation epot of China's uban family theate maket in 2004~2006, it is estimated that the maket scale of China's home theate system will each 6 million 900 thousand in the next 3 yeas. In addition, a vaiety of small household appliances also have a huge potential maket, which is an excellent business oppotunity fo the modified PP. e manufactues of pltic aw mateials in China have developed special mateials fo whing machines, such PP 1947 seies, K7726 seies and so on, and have been welcomed by the manufactues of whing machines. Theefoe, in the next few yeas, we should stengthen the development of PP special mateials fo household appliances in ode to meet the demand of maket change. Pltic pipeIn 2003, the total output of pltic pipes in China boke though 1 million 800 thousand T, up 23% fom the same iod. In the ealy days, PP pipes wee mainly used agicultual wate conveyance pipes. Howeve, due to the ealy fomance of poducts, thee wee still e poblems (such poo impact stength and poo aging esistance), and the maket could not be opened. With the Shanghai pltic building mateials factoy the fist intoduction of foeign advanced technology, the tanspotation of impoted PP-R mateial poduction of cold and hot wate in the pipe h been ecognized by the maket, many manufactues have the constuction of PP-R pipe poduction line, the pice fom the initial poduction of 20 thousand ~3 million /t continue to decline, but the shae of PP-R pipe mateial in the pltic pipe maket. Is still low. It is eflected that thee is a gap between the domestic PP-R mateials and the impoted mateials, and the quality needs to be impoved and impoved. Accoding to epots, South Koea h developed a new band of PP-R 112, a high pessue esistant wate supply pipe. The pipe poduced by this band can be used fo 50 yeas unde the condition of ulta-high pessue of 20 and 11.2MPa.The pltic pipe is one of the application of chemical building mateials in China's key poducts, the Ministy of constuction in 2001 had issued "on the stengthening of copolypopylene (PP-R, PP-B) cicula pipe poduction management and application wok, ked elevant depatments to jointly do a good job fom aw mateials, pocessing, quality and mateial use, installation and othe wok, to stictly contol PP the quality of the pipe mateials, in ode to do a bette job in China PP pipe poduction, application and pomotion wok.High meability mateial
