Mushure mekupera kwePatent, makambani eJapan akatangawo kutsvaga nekuvandudza nekugadzira. Mabhizimusi eJapan anowanzoitika estarm yeJapan, kugadzirwa kweJapan kwave kuwanda kupfuura United States panguva ino yekugadzira. Vamwe vanogadzira vanogadzirawo zvakanyanya kuiswa muUnited States neJapan, nyika dzekumadokero dzeEurope dzisati dzaunza pps. 2000, kugadzirwa kwePPS kunogona kusvika makumi mashanu ezviuru / a. PPS inoda yeJapan yakarondedzerwa ne39% yeiyo hombe, North America yakaverengerwa 32% yeWestern Europe accounted ye19% yeAsia accounted ye 16%.
Kutanga, zvinhu zvenyaya
1, kuisimbisa kwemagetsi (kunyanya kukwira-frequency-frequency insultation) kwakanaka, kuchena, kuwira pasi kune simbi chete kune prexiglass, kupokana kwemvura, kudzikisira kwemvura, kudzikisira kwemakunhu, kwakanaka kwemakemikari. Murazvo wakanaka kwazvo unodzora, zvisiri-zvinowoneka mapurasitiki.
2, Simba rakawanda, kuomarara kwakanaka kwazvo, asi brittle, nyore kuburitsa kushushikana, kusashivirira. Peturu uye imwe organic sols. Kushandiswa kwenguva refu kwekushisa kusvika kune makumi maviri nemashanu madhigirii, mumadhigiri mazana mana emhepo kana nitrogen kuti arambe akasimba. Kupfuura nekuwedzera kwema fiber kana kumwe kusimbisa zvinhu zvakagadziridzwa, simba rekukanganisa rinogona kuve rakavandudzwa, densitiki dzakawedzera kusvika. kugadzira kupisa-kupesana zvikamu. Insulation zvikamu nezviridzwa zvemakemikari. Zviridzwa zvemoyo uye zvimwe zvikamu.
Chechipiri, kuumbwa kuita
1. Amorphous zvinyorwa, kunyorova kwekunyorova zvidiki, asi zvinofanirwa kuomeswa mushure mekuumbwa.
2, kufamba pakati peBAB uye PC, kukurumidza kusimbisa, kudhakwa kweshoma, nyore kuora, sarudza yakakwirira jekiseni yekumanikidza uye kuremerwa. Mold tembiricha ye 100-150 madhigirii. Mainini taper anofanirwa kunge akakura, mumhanyi anofanira kunge akapfupika. Scope of application kazhinji inogona kuiswa kune iyo gadzira yePP PPE, PPS pepa uye zvimwe zvinhu, kazhinji zvinoshandiswa mukuvaka, imba.
Pps hunhu uye zvikumbiro
I. Maitiro
. Murazvo wakanaka unodzoreredza, its jekisi jekisi inosvika 44% kana kupfuura; Kuenzaniswa nemamwe mapurasitiki, iyo yakakwira nzvimbo yekudzoreredza muPurasitiki (yakachena PVC lexygen Index ye77%), psf ndeye 30%, PPP ndeyemoto yakakwira inodzora zvinhu mumapurasitiki. , Psf ndeye 30%, pa66 ndeye 29%, MPPO is 28%, PC ndeye 25%).
. Kugirazi fiber yakasimbiswa inosimbiswa ichavandudza simba rekukanganisa, kubva muna 27j / m kusvika 76j / m, kuwedzera kwe3 times; Insil Simba kubva 6mpa kusvika ku137mpa, kuwedzera kwe1 times. Iyo yakaomarara yePPS yakakwira kwazvo, zvisingawanzo muinjiniya mapurasitiki. Yakachena PPs inokotama modhilus kusvika ku3,8gpa, inorganic filthifel yekugadziridzwa inogona kusvika 12,6gpa, kuwedzera kwe5 times zvimwe. Uye kuomarara kweiyo yakakurumbira ppo ingori 2,55gpa, PC ndeye chete 2.1gpa. PPs pasi pekutakura kupokana, kuomesa kwakanyanya; Pfekai kupfeka kurwisa, huwandu hwehukuru hwechisimba chayo chiuru RPM chete PPS zvakare ine imwe nhanho yekuzvinyudza pachako. Mechancal Properties yePPS Tembiricha yekunzwa inogona kuve diki.
. Kupesana kwayo kwekupisa kwakafanana nePI, yechipiri chete kuF4 epurasitiki, iyo isingawanzo muTramosting plastiki.
. PPS arc kuramba kwakanaka, kwakafanana neTermoset plastics. pps inowanzo shandiswa mumagetsi ekushandisa kwemagetsi, dosi rayo rinogona kuverengerwa kweanosvika makumi matatu muzana.
. Pps yakagadzikana kune yakawanda acids, esters, Kotoni, ealdeshing hydrocarbons, etchatizing hydrocarbons, etichiziziziz Sodium hypochlorite, etc. pps yakanaka yekupaza radiation kuramba.
Chechipiri, chiyero chekushandisa
(1) Indasitiri yemotokari: Senge pane imwe yesimbi kugadzirwa kweiyo nzira yekudzora cylinder inotenderera mavharuvhu uye pmump impllers, pneumatic chiratidzo chiratidzo.
(2. Izvo zvakakodzera kuti zvinhu zvepamusoro zvemagetsi zvemagetsi zvine ambient tembiricha kupfuura 200 ℃; Inogona kushandiswa kugadzira jenarators uye mainjini neSubhu-Shindu, Magetsi Sharu Bubhu Brackets, Coils Coils, Scolding uye Blades, Etc.; Inogona kushandiswa pfuma yezviuru zvepamusoro nezvigadziko, zvimisikidzwa zvevateresi uye mapuranga anotyisa paterevhizheni; Izvo zvinoshandiswawo muindasitiri yemagetsi yekugadzirwa kwevatange, choke macoils uye kunotamba vatakuri vematunhu uye housera. uye magezi, akabatanidzwa vatakuri vematunhu; Iko kushandiswa kwekutanga-frequency performance, iyo yekugadzira yeH-kirasi yekuvhuvhuta chimiro uye trimmer capacitors.
. Rongedza PPS kugadzirisa nzira
I. Kugadzirisa maitiro
Resin Vagadziri vanopa PPS yeiyo yakaderera mhando (4000 ~ 5000), yakakwira crystallinity (75%) yeiyo chena poda, iyi pps yakanatswa yakananga, inogona kushandiswa chete pakupfira. Inoshandiswa kuumbwa kwekuumbwa kwePPs, inofanira kunge ichipfuura nekuchinjika kurapwa, kuitira kuti visikoka yeyamels ichisimuka. General Crosslinking mushure mekunyungudika index ye 10 ~ 20 yakakodzera; Girazi fiber yakasimbiswa pps melt index inogona kuve yakakura, asi isiri yakakura kupfuura 200.
PPs Cross-Lining Nzira ine iyo Thermal Cross-inobatanidza uye yemakemikari kuunganidzwa kwemhando mbiri, iyo iripo inopisa yekubatanidza-inobatanidza-batanidza-batanidza. Thermal Cross-Kubatanidza Kubatanidza Tembiricha ye150 ~ Comical Crosslinking inoda kuwedzera kurudziro yemuchinjiko, marudzi chaiwo, etert oxide ,,,,. Pps kunyangwe kuyambuka, asi kuyerera kwekuderera hakuna zvakawanda; Naizvozvo, dongo rinogona kushandiswazve katatu; PPS pachayo ine kusunungurwa kweMold, haigone kubatana neyakagadzirwa kuburitswa mumiririri; PPS mushure mekurapa kwekupisa kunogona kuvandudza iyo degree rekristunity uye kupisa kupisa tembiricha, kutumira-kurapwa mamiriro ezvinhu: Tembiricha 204 ℃, nguva 30min.
