Is féidir le Píopa HDPE Feabhas a chur ar an sreabhadh meáchain

2018-11-15

HDPE Pipe flower pattern causes: because the melt flow in the cylinder, the cylinder wall and the internal flow rate between the difference, when leaving the die, the whole melt and no resistance, the gap between the two becomes zero. It is the relative movement of the layers of the change, causing the mold at the melt flow of intense oscillation, leading to the occurrence of such phenomena!

Solution:

1, cuir cúntóirí isteach: mar bhreiseáin orgánacha silicone (breiseáin plaisteacha silicone) nó breiseáin pholaiméir Fu Fu (PPA).

2, is féidir leis an méadú cuí ar theocht an sruth leá a fheabhsú freisin!

Squeeze HDPE pipe, and sometimes because of temperature, and sometimes because of the type of raw material problems and more or less patterns, but sometimes it is to increase the temperature, change the plastic model or how much. There have been tested on the membrane head of the air ring overhead, or that elevation.

3, choose the rest assured HDPE pipe first to determine the appropriate material. In the past, the pipes used for water supply were mainly cast iron pipes. Outside the main sand cast iron pipe, indoor use of galvanized cast iron pipe, which can be divided into cold (electric) galvanized and hot galvanized two. Galvanized pipe as a water pipe, the use of a few years later, the tube produces a lot of rust, the outflow of yellow water not only pollution sanitary ware, and mixed with non-smooth wall breeding bacteria, rust caused by high levels of heavy metals in water, serious harm to human health. More importantly, the performance of such a superior HDPE pipe, the price is not expensive.

Is polyolefin teirmeaplaisteach é HDPE arna dtáirgeadh ag copolymerization eitiléine. Cé gur tugadh isteach HDPE i 1956, ach níor tháinig leibhéal aibí fós ar an bplaisteach seo. Tá an t-ábhar coitianta seo ag forbairt a chuid úsáidí agus margaí nua i gcónaí. Roisín teirmeaplaisteach. Ba é an chuma ar an HDPE bunaidh bán bólachta, i dtrasghearradh beag ná trédhearcach áirithe. Tá friotaíocht den scoth ag PE ag an chuid is mó de na saintréithe saoil agus ceimiceáin thionsclaíocha. Is féidir le cineálacha áirithe ceimiceán creimeadh ceimiceach a tháirgeadh, mar shampla oxidants creimneach (aigéad nítreach comhchruinnithe), hidreacarbóin aramatacha (xilene) agus hidreacarbóin halaiginithe (teitreaclóiríd charbóin). Tá an polaiméir neamh-hygrascópach agus tá friotaíocht maith uisce aige

PE can be manufactured with a wide range of different processing methods. Including extrusion such as sheet extrusion, film extrusion, pipe or profile extrusion, blow molding, injection molding and rotomoulding.

HDPE pipe is the traditional steel pipe, PVC drinking water pipe replacement products.

Ní mór go mbeadh brú áirithe ag píopa HDPE, de ghnáth meáchan móilíneach mór a úsáid, airíonna meicniúla roisín PE, mar shampla roisín HDPE. Tá neart teanntachta íseal ag roisín LDPE, friotaíocht bocht bocht, rigidity bocht, cobhsaíocht drochthoiseach le linn múnlú, agus deacracht i dtaca leis, agus níl sé oiriúnach mar ábhar do phíopaí brú soláthair uisce. Mar gheall ar a tháscairí sláinte níos airde, tá LDPE, go háirithe roisín LLDPE, ina ábhar coiteann chun píobáin uisce óil a tháirgeadh. Is beag, slabhra maith, soghluaisteacht éasca é próiseas éasca LDPE, LLDPE, agus dá bhrí sin tá raon roghnóireachta innéacs an leá leathan, de ghnáth MI sa 0.3-3g / 10min idir.
