PE umbhobho iipropati ezininzi ezizodwa

Iimpawu zokuxhathisa umbhobho we-1.PE?

I-Polyethylene yinto engasebenziyo enokumelana nokubola kwemithombo eyahlukeneyo yeekhemikhali.Akukho corrosion electrochemical, akukho anti-corrosion layer.

2. Iimpawu ezingavuziyo ze-PE tube?

Umbhobho wePolyethyleneubukhulu becala ithatha udibaniso lwe-welding (uqhagamshelo lwe-fusion eshushu okanye udibaniso lwe-fusion yombane), oluqinisekisa ngokubalulekileyo ubunikazi besixhobo sojongano, ulwakhiwo kunye nomzimba wombhobho, kwaye uqonde ukudityaniswa kombhobho nombhobho.Uvavanyo lungqina ukuba amandla okuqina kunye namandla okuqhushumba kojongano aphezulu kunomzimba wombhobho, kwaye akukho ngxaki yokuvuza xa kuthelekiswa namalungu erabha okanye amanye amalungu omatshini.

Iimpawu ze-3.PE eziphezulu zokuqina?

Umbhobho wePolyethylene luhlobo lombhobho wokuqina okuphezulu, ukunyuswa kwayo ngexesha lekhefu ngokuqhelekileyo kungaphezu kwama-500%, ukukwazi ukuziqhelanisa nokuhlaliswa kokungalingani kwesiseko sombhobho kunamandla kakhulu.Kwakhona luhlobo lombhobho olunomsebenzi obalaseleyo wokulwa nenyikima.Ngo-1995 inyikima yaseKobe eJapan, umbhobho wegesi we-polyethylene kunye nombhobho wokuhambisa amanzi yinkqubo yombhobho egciniweyo.Ngoko ke, iJapan emva kwenyikima ikhuthaza ngamandla ukusetyenziswa kombhobho we-PE kwintsimi yegesi.

I-tube ye-4.PE ineempawu ezintle eziguquguqukayo?

Ukuguquguquka kwe-polyethylene kuvumela iipayipi ze-polyethylene ukuba ziphindwe kwaye zinikezelwe ngobude obude ngaphandle kwesidingo seentlobo ezahlukeneyo zokudibanisa.Ukwakhiwa kwe-trenchless, isalathiso sombhobho we-polyethylene sinokutshintshwa ngokulula ngokweemfuno zendlela yokwakha, kwaye ubungakanani bokuqala kunye nobukhulu bunokubuyiselwa emva kokwakhiwa.

5. Indlela yokuqonda iimpawu ze-PE ityhubhu enokumelana kakuhle nemikrwelo?

Imikrwelo ibangela uxinzelelo lwexinzelelo kwizinto eziphathekayo, ezikhokelela ekungaphumeleli kombhobho.Xa kusetyenziswa itekhnoloji ye-trenchless, kunzima ukuyiphepha imikrwelo, nokuba kufakwe umbhobho omtsha okanye umbhobho omdala utshintshwa.Kwiminyaka yakutshanje, kuye kwangqinwa ukuba umbhobho we-PE80 we-polyethylene unokuxhathisa okungcono ekukhuleni okucothayo kunye nokumelana nokukrala, kwaye umbhobho we-PE100 we-polyethylene unokuxhathisa ngcono.Ke ngoko, umbhobho we-polyethylene usetyenziswa ngokubanzi kulwakhiwo lwetekhnoloji engenamsele.

6. Umbhobho we-PE uneempawu zokuxhathisa okulungileyo ngokukhawuleza kokuqhekeka kokuqhekeka.

Ukuqhekeka ngokukhawuleza kombhobho luhlobo lwengozi yengozi.Ukuqhekeka kukhula ngokukhawuleza ngesantya esithile, kubangela ukugqabhuka kwamashumi eemitha okanye kwanamawaka eemitha zemibhobho ngoko nangoko, kwaye iziphumo eziziphumo ziyingozi.Kwangoko ngeminyaka yee-1950, kwakukho iingozi ezininzi eziqhekeka ngokukhawuleza kumbhobho werhasi waseMelika.Ukuqhekeka ngokukhawuleza kombhobho wegesi ye-polyethylene akufumanekanga ekusebenzeni.Kwiminyaka yakutshanje, uphando oluninzi luye lwenziwa malunga nokuqhekeka ngokukhawuleza kombhobho kwihlabathi.Iziphumo zibonisa ukuba ukuxhathisa kombhobho we-polyethylene ukusabalalisa ukusabalalisa kuphakathi kwezona zilungileyo.
