HDPE Pipe Good Elasticity, High Impact Resistance, Non-toxic

2018-11-15

Feadán HDPE

The reason is that the melt flow in the cylinder, the flow between the cylinder wall and the inner wall of 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, add auxiliaries: like organic silicone additives (silicone plastic additives) or Fu Fu polymer additives (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, roghnaigh an chéad phíopa HDPE eile cinnte chun an t-ábhar cuí a chinneadh. San am atá caite, ba phíopaí iarainn theilgthe iad na píopaí a úsáideadh le haghaidh soláthar uisce. Lasmuigh den phíobán iarann ​​teilgthe is mó, gaileadh píopa iarainn teilgthe galbhánaithe, a fhéadfar a roinnt ina dhá fhuaim (leictreacha) ghalbhánuithe agus te galvanized. Píopa ghalbhánuithe mar phíobán uisce, úsáid roinnt blianta ina dhiaidh sin, tá an chuid is mó de meirge, an t-eis-sreabhadh uisce buí, ní hamháin ar earraí sláintíochta truaillithe, agus measctha le baictéir pórú neamh-réidh, meirge de bharr leibhéil arda de miotal trom in uisce, dochar tromchúiseach do shláinte an duine. Níos tábhachtaí fós, tá feidhmíocht píopa HDPE den sórt sin níos fearr, níl an costas costasach.

Drainage HDPE pipe is the traditional PVC, pig iron pipe drinking water pipe replacement products. Drainage pipe must be able to prohibit the inevitable pressure, usually choose the machine function is better, large molecular weight PE resin, such as HDPE resin, and LDPE resin pressure, tensile strength is low, poor steel, forming the proportion of poor stability when polished , And the connection problem, not suitable as a drainage pressure pipe material.

From the high temperature function, PE pipe with the temperature rise of its function to quickly reduce the use of temperature of ± 60 ° during which the general use of cold water for the main, mainly for the drainage pipe on the main road, which after the home Of the drainage pipe selection, will choose PPR pipe.

Tá níos mó meáchain píopa PE, dea-elasticity, friotaíocht ard-thionchar, neamh-tocsaineach, praghas aonad níos saoire, feidhmíocht íseal teochta níos fearr anois, ní mór tógáil chathrach, eastát réadach, monarchana, tógáil caomhnaithe uisce agus soláthar uisce eile agus píblíne draenála.

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). Níl an polaiméir hygrascópach agus tá friotaíocht maith aige

Is féidir PE a mhonarú le réimse leathan modhanna próiseála éagsúla. Lena n-áirítear easbhrúite mar easbhrúite bileog, easbhrúite scannáin, easbhrúite píopa nó próifíl, múnlú buille, múnlú insteallta agus rotomoulding.

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

The roughness coefficient of the HDPE pipe is between 0.009 and 0.01, which is much smaller than the roughness coefficient of the reinforced concrete pipe (0.013-0.014). It can be seen that compared with the reinforced concrete pipe with the same diameter, In the traffic will be greater. For the municipal drainage works, through the application of HDPE off, can effectively increase the amount of emissions, thereby reducing the construction of sewage pumping stations, reducing the cost of urban sewage treatment.

HDPE pipe is a flexible pipe, in its interface is usually used in a flexible connection, it has a good sealing performance, and has a strong ability to adapt to the pipeline foundation uneven settlement, anti-leakage is very strong. Compared with the clean concrete pipes used in the traditional municipal drainage works, the HDPE pipe is flexible on the material and foundation, and it can play an effective anti-underground pollution because of its good sealing and good anti-leakage.


HDPE pipe and the traditional reinforced concrete pipe is different from the use of high-density polyethylene inert materials, so a variety of chemical have a strong corrosion resistance, so in high acid, high alkali or sewage discharge has a good effect The In the underground use, HDPE pipe can be used for more than 50 years, while the reinforced concrete pipe is susceptible to corrosion in the soil, usually in the service life of about 20 years. It can be seen, compared with the traditional reinforced concrete pipe, HDPE has a longer or useful life.
