Naqshadeynta si loo sameeyo weel godan ayaa ah arrinka ugu weyn ee isticmaalka HDPE.Caadi ahaan badeecooyinka dharbaaxada godan waxa loo qaybiyaa weel badeecadeed iyo wax soo saar warshadeed iyo qaab dhismeed.Weelasha badeecada waxaa kaliya loo isticmaalaa baakadaha kiimikooyinka, saliidaha iyo cuntada.Wax soo saarka warshadaha iyo qaab-dhismeedku waa aag si degdeg ah u koraya oo ah badeecooyinka qaabaynta dharbaaxada godan.Korodhka isticmaalka wax soo saarka warshadaha waxaa inta badan keenay horumarinta tignoolajiyada wax soo saarka ee cusub, oo ay ku jiraan dharbaaxo waaweyn oo wax soo saara iyo qaybaha warshadaha.

Durbaan: qaybta ugu weyn ee 200-230L HDPE baaldiga warshadaha, sababtoo ah xasilloonida cabbirkeeda, badbaadada gaadiidka, caabbinta kiimikada iyo dhinacyada kale ee waxqabadka ugu fiican.Sii wadista barakicinta durbaanka birta, ma jiro polymer kale oo kula tartami kara HDPE suuqan.

Durbaannada weelka IBC: Sanadihii ugu dambeeyay, durbaanka weelka IBC ayaa si xawli ah ugu korayay wadamada shisheeye.Kobaca sanadlaha ah ee suuqa Yurub waa qiyaastii 8% ~ 10%, kobaca degdega ah ee foosto baakadaha IBC ee Mareykanka waa qiyaastii 20%.Baaldi IBC waxay leedahay faa'iidooyinka badbaadinta in ka badan 30% booska gaadiidka, kharashka gaadiidka yar, qaadista habboon iyo wixii la mid ah.Sanadihii la soo dhaafay, baaldi IBC ayaa si degdeg ah ugu soo koraya Shiinaha.

Waqtigan xaadirka ah, alaabada waaweyn ee HDPE ee godan, 220L xiran L-ring VAT iyo weelka IBC sida alaabada ugu muhiimsan, ayaa si weyn loogu isticmaalay kiimikooyin kala duwan oo khatar ah oo aan khatar ahayn, saliid iyo dareerayaal kale, si tartiib tartiib ah u beddela weelka birta.

Walaxda gaarka ah ee weelasha godan ayaa leh cufka molecular qaraabo sare ah iyo ballaca cufnaanta molecular qaraabo ballaaran, iyo heerka qulqulka dhalaalka (MFR) (190℃, 21.6kg) waa inta u dhaxaysa 2 iyo 10 g/10 min.Miisaanka molecular ee sarreeya wuxuu dammaanad qaadi karaa xoogga sare ee dhalaalka wuxuuna yareynayaa fidinta tooska ah ee billet extruded.Ku habboon qaybinta cufka molecular qaraabo ah si loo buuxiyo shuruudaha waxqabadka habaynta.Ku darida ku habboon ee monomer labaad ee kobolymerization si loo horumariyo waxqabadka ESCR si loo buuxiyo shuruudaha waxqabadka.

HDPE gudaha sumad gaar ah oo wayn

Warshado bannaan oo waaweyn ayaa si degdeg ah u koraya.Ilaa hadda sida Shiinuhu ka walaacsan yahay, 200 L ee durbaanka L-ring ee xiran ayaa weli ah kan caadiga ah, awoodda horumarintuna wali waa weyn tahay, laakiin tartanku waa mid aad u daran.Waqtiga xaadirka ah,QilU 1158,Korea DaelIM 520, Shanghai JinFEI 571, Shiinaha Shipping iyo SHELL 4261, Maoming PETROCHEMICAL TR580, Xinjiang DushanZI 5420, Shirkadda ZhongSHA 4560 ayaa soo galay goobtan.Warshadaha foosto baakadaha IBC waxay leedahay rajooyin ballaadhan, marka la barbar dhigo heerka horumarinta adduunka ee hadda dalkeenu leeyahay farqi weyn, waxaa jiri doona isbedel weyn mustaqbalka, hadda, gudaha ayaa Zhongsha Tianjin 4560UA, Qilu petrochemical 1158, QHB07, ka mid ah kaas oo soosaarkii 1158 uu yahay mid xasiloon.

Ugu dambayntii, WARSHADDA BAABUURTA SI xawli ah ayey u horumaraysaa, Waxayna noqotay warshad tiir u ah dhaqaalaha qaranka, iyadoo heerka caannimada suuqa ee Haamaha shidaalka caaga ah uu gaadhay in ka badan 60%.Baahida loo qabo maaddooyinka gaarka ah ee polyetylenka ee haamaha shidaalka baabuurta iyo qaybaha baabuurta ayaa ah mid aad u weyn, laakiin fikradda ilaalinta deegaanku waa qoto dheer oo guud ahaan dusha sare ee macro ma fiicna, taas oo la filayo inay xaddiddo baahida warshadaha waaweyn ee bannaan ilaa xad.
