PC imhando yeinjiniya epurasitiki ine mashandiro akanaka mune ese maficha. Iyo ine mabhenefiti makuru mukupikisa kupikisa, kupisa kupisa, kuumba dimensional kugadzikana uye murazvo wemoto. Naizvozvo, inoshandiswa zvakanyanya mumidziyo yemagetsi, mota, midziyo yemitambo nemimwe minda. Zvisinei, PC molecular chains ine nhamba yakawanda yebenzene mhete, izvo zvinoita kuti zviome kuti maketani emaketani afambe, zvichiita kuti kunyunguduka kukuru kwePC. Munguva yekugadzirisa, iyo PC molecular cheni inotungamirwa. Mushure mekugadzirisa, mamwe emaketani emamorekuru asina kucheneswa zvachose muchigadzirwa anowanzo dzokera kumamiriro avo echisikigo, izvo zvinokonzeresa kuwanda kwekunetseka kwakasara muPC jekiseni rakaumbwa zvigadzirwa, zvichikonzera kutsemuka panguva yekushandisa chigadzirwa kana kuchengetedza; panguva imwecheteyo, PC ndeye notch-sensitive material. Izvi zvinokanganisa zvinoderedza kuwedzera kwekuwedzera kwePC applications.

Kuti uvandudze iyo notch senitivity uye kusagadzikana kupaza kwePC uye nekuvandudza mashandiro ayo ekugadzirisa, toughening agents anowanzo shandiswa kuomesera PC. Parizvino, izvo zvinowedzera zvinowanzo shandiswa paPC kuomesa gadziriso pamusika zvinosanganisira acrylate toughening agents (ACR), methyl methacrylate-butadiene-styrene toughening agents (MBS) uye toughening agents anoumbwa nemethyl methacrylate segoko uye acrylate uye silicone semusimboti. Aya anoomesa maajenti ane kuenderana kwakanaka nePC, saka iwo anoomesa maajenti anogona kuparadzirwa zvakaenzana muPC.

Iri bepa rakasarudza 5 mhando dzakasiyana dze toughening agents (M-722, M-732, M-577, MR-502 uye S2001), uye yakaongorora mhedzisiro yeanoomesa maajenti paPC thermal oxidation kuchembera zvivakwa, 70 ℃ mvura inofashaira zvivakwa, uye kupisa kwakanyorova (85 ℃/85%) kuchembera zvivakwa kuburikidza nekuchinja muPC melt kuyerera mwero, kupisa deformation tembiricha. uye mechanical properties.

Main equipments:

UP-6195: kunyorova kupisa kuchembera bvunzo (yakakwirira uye yakaderera tembiricha yakanyorovaheat test chamber);

UP-6196: yakakwirira tembiricha yekuchengetedza bvunzo (chaiyo ovheni);

UP-6118: tembiricha yekuvhunduka bvunzo (inotonhora uye inopisa kuvhundukatest chamber);

UP-6195F: TC yakakwira uye yakaderera tembiricha kutenderera (kukurumidza tembiricha shanduko yekuyedza kamuri);

UP-6195C: tembiricha uye humidity vibration bvunzo (matatu akakwana ebvunzo makamuri);

UP-6110: yakakwira yakakwirisa kushushikana bvunzo (yakanyanya kukurumidza kukurumidzakuchembera test chamber);

UP-6200: zvinhu UV kuchembera bvunzo (ultraviolet kuchembera bvunzo kamuri);

UP-6197: munyu wekupfapfaidza corrosion test (salt spray test room).

Performance test uye chimiro chechimiro:

● Edza kunyunguduka kwehuwandu hwekuyerera kwezvinhu zvinoenderana neISO 1133 standard, mamiriro ekuedzwa ndeye 300 ℃/1. 2 kg;

● Edza kusimba kwesimba uye kureba pakuputsika kwezvinhu zvinoenderana neISO 527-1 chiyero, chiyero chekuyedza 50 mm / min;

● Edza simba rekugadzirisa uye flexural modulus yezvinyorwa maererano ne ISO 178 standard, chiyero chekuedza ndeye 2 mm / min;

● Edzai kusimba kwesimba rezvinhu maererano ne ISO180 chiyero, shandisai notch yekugadzira muchina kugadzirira "V"-yakaita notch, kudzika kwenotch i2 mm, uye sampuli inochengetwa pa -30 ℃ kwe4 h pamberi. iyo yakaderera-tembiricha inokanganisa bvunzo;

● Edza kupisa kwekushisa kwekushisa kwezvinhu maererano ne ISO 75-1 chiyero, chiyero chekupisa chiri 120 ℃ / min;

●Yellowness index (IYI) bvunzo:jekiseni rekugadzira parutivi kureba kwakakura kupfuura 2 cm, ukobvu i2 mm Iyo skweya color plate inoiswa mukupisa okisijeni kuchembera bvunzo, uye ruvara rweplate yeruvara pamberi uye mushure mekuchembera inoedzwa ne spectrophotometer. Chimbo chinoda kucheneswa chisati chaongororwa. Imwe neimwe ndiro yemavara inoyerwa katatu uye iyo yero index yevaravara inorekodhwa;

●SEM ongororo:Iyo jekiseni yakaumbwa sample strip inochekwa, goridhe inopfapfaidzwa pamusoro payo, uye morphology yayo yepasi inocherechedzwa pasi peimwe voltage.
