Tshuab moulding los ua cov thawv hollow yog ib qho tseem ceeb ntawm kev siv HDPE.Feem ntau cov hollow tshuab moulding cov khoom tau muab faib ua cov khoom ntim thiab cov khoom lag luam thiab cov khoom siv.Cov thawv ntim khoom tsuas yog siv rau ntim cov tshuaj, cov roj nplua nyeem thiab khoom noj.Thiab cov khoom lag luam thiab cov qauv tsim yog thaj chaw loj hlob sai ntawm hollow tshuab molding khoom.Kev nce hauv kev noj cov khoom lag luam feem ntau yog tsav los ntawm kev txhim kho hauv cov thev naus laus zis tshiab, suav nrog cov tshuab loj loj molding hollow cov khoom thiab cov khoom lag luam.
Nruas: qhov loj tshaj plaws ntawm 200-230L HDPE muaj thoob, vim nws qhov ruaj khov, kev nyab xeeb kev thauj mus los, tshuaj tsis haum thiab lwm yam ntawm kev ua haujlwm zoo heev.Txuas ntxiv hloov cov nruas steel, tsis muaj lwm yam polymer uas tuaj yeem sib tw nrog HDPE hauv kev ua lag luam no.
IBC thawv nruas: Nyob rau hauv xyoo tas los no, IBC thawv nruas tau loj hlob sai nyob rau hauv txawv teb chaws.Kev loj hlob txhua xyoo ntawm European lag luam yog kwv yees li 8% ~ 10%, thiab kev loj hlob sai ntawm IBC ntim cov thoob hauv Tebchaws Meskas yog li 20%.IBC thoob muaj qhov zoo ntawm kev txuag ntau dua 30% ntawm qhov chaw thauj mus los, tus nqi thauj mus los tsawg, nqa yooj yim thiab lwm yam.Nyob rau hauv xyoo tas los no, IBC thoob tau loj hlob sai hauv Suav teb.
Tam sim no, cov khoom loj HDPE hollow, 220L kaw L-ring VAT thiab IBC thawv ua cov khoom tseem ceeb, tau siv dav hauv ntau yam tshuaj txaus ntshai thiab tsis muaj kev phom sij, roj thiab lwm yam kua, maj mam hloov lub thawv hlau.
Cov khoom siv tshwj xeeb rau cov thawv ntim loj loj muaj cov txheeb ze molecular loj thiab cov txheeb ze molecular dav dav, thiab cov yaj ntws tus nqi (MFR) (190 ℃, 21.6kg) yog nruab nrab ntawm 2 thiab 10 g / 10 min.Lub siab molecular hnyav tuaj yeem lav lub zog siab ntawm yaj thiab txo cov ntsug txuas ntxiv ntawm extruded billet.Tsim nyog tus txheeb ze molecular loj faib kom tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm.Tsim nyog ntxiv ntawm ob monomer rau copolymerization los txhim kho kev ua tau zoo ntawm ESCR kom tau raws li qhov yuav tsum tau ua.
Hauv tsev HDPE loj hollow khoom tshwj xeeb hom
Kev lag luam loj hollow tab tom txhim kho sai.Raws li Tuam Tshoj muaj kev txhawj xeeb, 200 L kaw L-ring nruas tseem yog lub hauv paus, thiab kev txhim kho muaj peev xwm tseem zoo, tab sis kev sib tw yog qhov hnyav heev.Nyob rau tam sim no,TIAB SA 1158,Kauslim DaelIM 520, Shanghai JinFEI 571, Tuam Tshoj Shipping thiab SHELL 4261, Maoming PETROCHEMICAL TR580, Xinjiang DushanZI 5420, ZhongSHA Company 4560 tau nkag mus rau hauv daim teb no.IBC ntim ntim kev lag luam muaj kev cia siab dav, piv nrog rau theem kev loj hlob hauv ntiaj teb tam sim no ntawm peb lub teb chaws muaj qhov sib txawv loj, yuav muaj kev hloov pauv zoo rau yav tom ntej, tam sim no, lub tsev muaj Zhongsha Tianjin 4560UA, Qilu petrochemical 1158, QHB07, ntawm uas 1158 cov zis yog qhov ruaj khov.
Thaum kawg, AUTOMOBILE INDUSTRY DEVELOPS sai heev, THIAB tau dhau los ua ib qho kev lag luam tseem ceeb ntawm NATIONAL ECONOMY, THIAB LUB CHAW UA HAUJ LWM tus nqi ntawm cov roj yas yas tau mus txog 60%.Qhov kev thov rau polyethylene cov ntaub ntawv tshwj xeeb rau tsheb roj tso tsheb hlau luam thiab qhov chaw pib yog qhov loj heev, tab sis lub tswv yim ntawm kev tiv thaiv ib puag ncig yog qhov sib sib zog nqus thiab tag nrho cov macro nto tsis zoo, uas yuav tsum txwv qhov kev thov ntawm kev lag luam loj hollow rau qee yam.
