iimveliso

Intlaka ye-HDPE yombhobho otyatyiweyo ophindwe kabini,
HDPE resin for bellow, I-resin ye-HDPE ye-bellows ephindwe kabini,

Ngenxa yokusebenza kakuhle kombhobho we-HDPE owenziwe kabini eludongeni, kunye nophuhliso olukhawulezayo loluntu, ngokuthe ngcembe ithathe indawo yombhobho wesintu, izisa lula ngakumbi kubomi babantu.Oku kungenxa yokuba umbhobho we-HDPE onodonga oluphindwe kabini ikhuselekile kwaye ilungele ngakumbi kunombhobho wentsimbi wesiqhelo kunye nombhobho wekhonkrithi kwiinkalo ezininzi, kwaye iyamkelwa nangamaphulo okwakha kwaye isetyenziswa ngokubanzi nangakumbi kwiiprojekthi ezahlukeneyo zemibhobho.

Namhlanje, makhe sichaze ngokweenkcukacha ukuba zeziphi iingenelo ze-HDPE ezinodonga oluphindwe kabini?

1. Umbhobho we-HDPE owenziwe kabini wodonga unobuxhakaxhaka bokucinezela.I-hdpe i-double-bellows ephindwe kabini inamandla amakhulu okucinezela kunemivumbo yemveli phantsi kweemeko ezifanayo zoxinzelelo.Ngenxa yokwakhiwa kwemilo ekhethekileyo, udonga lwayo lwangaphandle lugutyungelwe, olunokunyusa ukuqina kombhobho, ukunika ukuchasana okunamandla kuxinzelelo lwangaphandle.

I-2, i-HDPE yodonga oluphindwe kabini lombhobho inexabiso eliphezulu lokusebenza.Ngaphantsi komthwalo ofanayo, i-HDPE i-double-wall corrugated pipe idinga kuphela ukuhlangabezana neemfuno zodonga oluncinci lombhobho, kuphela izinto eziluhlaza zeminye imibhobho zingasetyenziswa, xa kuthelekiswa neendleko zokugcinwa kweendleko zobunjineli.Esi sesinye sezizathu zokuba kutheni iiprojekthi ezininzi namhlanje zikhetha.

I-3, isantya sokwakhiwa kwe-HDPE-double-bellows sikhawuleza.Ngenxa yodonga olucekeceke lwe-HDPE olunodonga oluphindwe kabini, kwinkqubo yokwakha, nokuba iyalayisha kwaye ikhuphe okanye idityaniswe, ilunge ngakumbi kunombhobho wendabuko, kwaye ukugcinwa kwamva kulula.Ukuba ikwindawo eyakhiwe rhabaxa, inokubonisa izibonelelo ze-HDPE ezinodonga oluphindwe kabini.

Ezi ziipropati ze-HDPE ze-bellows eziphindwe kabini, kuba ziyikhemikhali yokuvelisa umbhobho weplastiki, ikwazi ukuguquguquka okulungileyo, kunye neempawu zokusingqongileyo, ngoko ke, inokusetyenziswa ngokubanzi kubunjineli bemibhobho.

Ibakala lombhobho we-HDPE linokusabalalisa okubanzi okanye kwe-bimodal ubunzima be-molecular.Inoxhathiso oluqinileyo lwe-creep kunye nokulinganisela okulungileyo kokuqina kunye nokuqina.Yomelele kakhulu kwaye ine-sag ephantsi xa isenziwa.Imibhobho eveliswa kusetyenziswa le resin inamandla amahle, ukuqina kunye nokumelana nempembelelo kunye nepropathi egqwesileyo ye-SCG kunye ne-RCP.

I-resin kufuneka igcinwe kwindawo yokugcina impahla, eyomileyo kwaye kude nomlilo kunye nelanga elithe ngqo.Akufunekanga ifunjwe kwindawo evulekileyo.Ngexesha lokuthutha, izinto eziphathekayo akufanele zibekwe kwilanga elinamandla okanye imvula kwaye akufanele zihanjiswe kunye nesanti, umhlaba, isinyithi esilahliweyo, amalahle okanye iglasi.Uthutho kunye nezinto eziyityhefu, ezidlekayo nezinokutsha akuvumelekanga ngokungqongqo.

Isicelo

Inqanaba lombhobho we-HDPE lingasetyenziselwa ukuveliswa kwemibhobho yoxinzelelo, njengemibhobho yamanzi ecinezelekileyo, imibhobho yegesi yepetroli kunye neminye imibhobho yoshishino.Isenokusetyenziswa ukwenza imibhobho engacinezelekiyo njengemibhobho etyatyiweyo enodonga oluphindwe kabini, imibhobho yodonga olunomngxuma, imibhobho yesilicon-core, imibhobho yokunkcenkceshela yezolimo kunye nemibhobho edityanisiweyo ye-aluminiyamplastics.Ukongeza, nge-extrusion esebenzayo (i-silane cross-linking), ingasetyenziselwa ukuvelisa imibhobho ye-polyethylene edibeneyo (PEX) yokubonelela ngamanzi abandayo nashushu.
