1. Airíonna meicniúla: ard-neart, friotaíocht tuirse, cobhsaíocht tríthoiseach, agus creep beag (athrú beag faoi choinníollacha teocht ard); is earraí inchaite coitianta iad i gcultúr na gceall. Úsáidtear iad go príomha le haghaidh saothrú cealla mamaigh, cealla feithidí, cealla giosta, cealla fungacha agus cealla fionraí eile. Is amhábhar a úsáidtear go coitianta é polycarbonate (PC). Tá ábhar PC sách ard. Ina theannta sin, tá na tréithe seo a leanas ag an ábhar seo:
2. Friotaíocht aosaithe teasa: sroicheann an t-innéacs feabhsaithe teocht UL 120 ~ 140 ℃ (tá friotaíocht fadtéarmach aosaithe lasmuigh an-mhaith freisin);
3. Friotaíocht tuaslagóir: gan scoilteadh struis;
4. Cobhsaíocht uisce: tá sé éasca a dhianscaoileadh in uisce ag teocht ard (bí cúramach i dtimpeallacht ardteochta agus ard-taise);
5. Feidhmíocht inslithe: den scoth (is féidir leis feidhmíocht leictreach cobhsaí a choinneáil fiú faoi thaise agus teocht ard, is ábhar idéalach é chun páirteanna leictreonacha agus leictreacha a mhonarú);
6. Comhéifeacht tréleictreach: 3.0-3.2;
7. Friotaíocht stua: 120s;
8. Próiseasacht mhúnlú: múnlú insteallta gnáth-trealamh nó múnlú easbhrúite.
Is iad seo thuas tréithe ábhartha an
h
igh-éifeachtacht . Áirítear leis an teicneolaíocht próiseála is féidir a úsáid le haghaidh an t-ábhar seo múnlú insteallta, easbhrúite, múnlú, múnlú buille, srl. teocht. Cuirfidh sé faoi deara an táirge dath turbid bán, sreang airgid agus boilgeoga a tháirgeadh. Tá cumas dífhoirmithe ard leaisteach éigeantach ag PC ag teocht an tseomra.erlenmeyer fleascáin chroitherlenmeyer shake flasks. The processing technology that can be used for this material includes injection molding, extrusion, molding, blow molding, etc. It must be pre-dried before molding, the moisture content should be less than 0.02%, and the trace moisture is processed at high temperature. It will cause the product to produce white turbid color, silver wire and bubbles. PC has a considerable forced high elastic deformation ability at room temperature.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
