Uamea mata skeleton paipa polyethylene
Fa'atatauga
I le 20 tausaga ua tuanaʻi, o paipa palasitika fou ua faʻaaogaina lautele i le taulaga, kesi ma le eletise e faʻaaogaina vai. Aemaise lava i le faʻaauau pea o le faʻaleleia ma le faʻafouina o le polyethylene polymerization technology, o loʻo faʻateleina le maualuga o le malosi o mea polyethylene. Ina ia faalautele atili le tele o tulaga mamafa mo paipa palasitika, aemaise lava i tausaga talu ai nei, e ala i le suʻesuʻeina o tekinolosi interdisciplinary, o le uʻamea-palasitika tekinolosi tuʻufaʻatasia faʻafeiloaʻi ua manuia foia faafitauli o le polyethylene (PE) paipa i tulaga o le maualuga o le mamafa, anti- pala, ma lelei le ta'amilosaga lautele. Fa'aaogaina i le lautele lautele o felauaiga felauaiga vai.
Fauga: O lenei oloa o se faʻavaa faʻamalosia ma se vaega autu o le faʻaauau pea ona manuʻa uaea uʻamea maualuga pe a maeʻa togafitiga faʻapipiʻi, ma se kelu faʻafefe vevela ma palasitika e tuʻufaʻatasia i totonu o se paipa atoa e ala i le faʻaogaina o auala.

Fa'atinoga o le tamaoaiga o le paipa
O le faʻaaogaina o le polyethylene maualuga e pei o mea i totonu ma fafo, o le uʻamea uʻamea polyethylene palasitika paipa tuʻufaʻatasia o loʻo i ai le faʻatinoga sili ona lelei o oloa paipa polyethylene. Ona o le aafiaga o le auivi uʻamea, o le paipa tuʻufaʻatasia o le tulaga mamafa tutusa e iai se mafiafia puipui laʻititi nai lo paipa palasitika mama. O le lelei o le taamilosaga a агеа e sili atu, ma o le lelei o le pala ma le ofuina o mea e fa'amautinoa ai o le ola tautua o le paipa e mafai ona pei o le 50 tausaga, lea e fa'aleleia atili ai le tamaoaiga o le paipa.
Fa'amalosi le auivi e taofiofia lelei ai ta'e
O le faʻaaogaina o le uʻamea faʻamalosi e faʻamalosia lelei le faʻaogaina o le gaosiga o le taʻavale masani ma le faʻavaveina o mea polyethylene, ma e maualuga atu le malosi o le compressive (o le mamafa o le paipa vai e oʻo atu i le З.5МРа) ma tagata ese сгеер. tete'e, A'afiaga maualuga tete'e, ma ona fa'ailoga fa'atinoga o paipa polyethylene sili.
