i-masterbatch eguquliwe ye-high density polyethylene bellows enobubanzi obukhulu
i-masterbatch eguquliwe ye-high density polyethylene bellows enobubanzi obukhulu,
I-HDPE engezansi, I-HDPE yepayipi eligoqiwe,
Lo mkhiqizo ukhiqizwa kusetshenziswa ubuchwepheshe benqubo ye-UNIPOL™.Ihloselwe ukusetshenziswa ekufakweni kwamapayipi lapho amandla esikhathi eside e-hydrostatic kanye nokumelana nokukhula kancane kokuqhekeka kuyadingeka.Izicelo ezifanele zihlanganisa amapayipi okusabalalisa igesi yemvelo, amapayipi amakhulu ezimbonini amakhulu, izimayini, indle, nezintambo zikamasipala zokuhlinzeka ngamanzi.Ukuthobela Amazinga Ezimboni: ASTM D 3350: ukuhlukaniswa kwamaseli – Kwemvelo – PE345464A – Mnyama – PE345464C (Bheka AMANOTHI A) Isikhungo Sepayipi Lepulasitiki (PPI): TR-4 – Ipayipi Lemvelo – DGDB-2480 NT 3408 — ASTM PE3608 ipayipi HDsi grade 0p @ 73°F – Ipayipi Elimnyama – DGDB-2480 BK 3408 (Bheka Amanothi B) — Ibanga lepayipi le-ASTM PE3608 – 1600psi HDB @ 73°F kanye no-800psi HDB @ 140°F National Sanitation Foundation (NSF) Standard 14 and 61 – Natural Pipe – DGDB-2480 NT 3608 – Ipayipi Elimnyama – DGDB-2480 BK 3608 (Bheka AMANOTHI B) Bheka imithethonqubo ukuze uthole imininingwane ephelele.AMANOTHI: (A) Izinombolo zokuqala ezinhlanu zokuhlukaniswa kwamaseli zisekelwe kunhlaka yemvelo.Inombolo yokugcina kanye nohlamvu kusekelwe ku-resin emnyama (inhlaka yemvelo kanye no-6.5% DFNF-0092).(B) I-resin yemvelo ekhishwe ngaphansi kwezimo ezifanele nge-carbon black masterbatch DFNF-0092 (6.5%).
Isebenzisa
1.Izicelo zepayipi
2.Amapayipi okusabalalisa igesi yemvelo
I-3.I-diameter enkulu yamapayipi embonini
4.Izimayini
5.Indle
6.Izintambo zikamasipala zokuhlinzeka ngamanzi
I-HDPEI-Bellows, eyaziwa ngokuthi i-PE curragted pipe, iwuhlobo olusha lwepayipi elikhanyayo elenziwe nge-polyethylene ephezulu.Inezici zesisindo esilula, ukumelana nokucindezela okuphezulu, ukuqina okuhle, ukwakhiwa okusheshayo nokuphila isikhathi eside.
Ububanzi bemibhobho ye-HDPE enodonga oluphindwe kabili ekhiqizwa e-China φ400 ~ φ1400mm, engadingi nje kuphela uketshezi oluningi lwezinto zokwakha ukuze kuhlangatshezwane nezidingo zokucubungula imishini, kodwa futhi kuhlangabezana nezidingo zebanga lokuqina kwendandatho yemikhiqizo (isigaba se-S2 sikhulu kune-8KN /m2, kwento ethile, uma ubukhulu bebubanzi buba bukhulu, kwehlisa inani lokuqina kwendandatho. Ngakho lokhu kuletha ubunzima obuthile ekukhetheni izinto zokwakha. Ngemva kokuhlolwa okuningana, i-Qilu HDPE2480 ingahlangabezana nezidingo zayo zokukhiqiza, kodwa ukuqina kwendandatho umkhiqizo awukwazi ukufinyelela ku-8KN/m2. Inani lokuhlola ukuqina kwendandatho ekushiseni okujwayelekile (23±2℃) ngu-6.2kN/m2, okudinga ukuguqulwa kwezinto futhi kudinga lokho ngaphandle kokunciphisa ukusebenza kwe-HDPE2480 yasekuqaleni. Okusho ukuthi, ngaphansi kwesimo sokuqinisekisa ukuguquguquka kwendandatho, umthelela ophansi wezinga lokushisa kanye namandla omthelela we-notch womkhiqizo; Thuthukisa imoduli yokugoba yezinto ukuze uqinisekise izinga lokuqina komkhiqizo.
Inqubo yokukhiqiza yokugcwalisa okuphezulu okuguquliwe kwe-masterbatch yezikhala ezinkulu ze-polyethylene ezixinene kakhulu ezingahlangabezana nezidingo zokuguquguquka kwendandatho ye-caliber bellows enkulu, umthelela ophansi wokushisa, amandla omthelela we-notch kanye nokufa okuthile kokugoba.
Ihlanganiswe ne-30-50% D50 = 2-7 μm i-ultrafine calcium carbonate kanye ne-50-70% ye-ultrafine talc powder, i-powder composite yalungiswa.
Inani eligcwaliswayo lezinto eziyinhloko eziguquliwe ezenziwe ngezinto eziyimpushana ezihlanganisiwe zingafinyelela ku-50% ku-HDPE ezinobubanzi obukhulu.Ngaphansi kwesimo se-HDPE∶ okuyinhloko okushintshiwe okusha = 50∶50, isisindo sepayipi elinesikali esifanayo sikhuphuka kuphela 5 ~ 6%, futhi imoduli yayo yokugoba ifika ku-1360Mpa.Ukumelana okuqinile nomthelela wezinto ezibonakalayo ezinamandla okuguquguquka kwe-24Mpa kufana nalokho okuguquliwe kwasekuqaleni uma kugcwaliswe ngo-30% : amandla okubamba ngu-≥24Mpa, kanye nenombolo yokuphuka yamasampuli angu-10 anamandla okumelana nomthelela ku-0℃ ingaphansi kokungu-1, ehlangabezana ngokugcwele nezimfuneko zekhwalithi zokuvunguza kwe-HDPE yezinga elikhulu.
Isebenzisa u-30 ~ 50% D50 = 2 ~ 7μm superfine calcium carbonate kanye no-50 ~ 70% superfine talc powder ukuze ixube ibe yimpushana eyizingxenye eziyi-100, yengeze i-0.2 ~ 1 ingxenye ehlanganisa i-ejenti ehlanganisa impushana bese inyakaza imizuzu emi-5 ~ 10 120 ~ 140℃.Bese wengeza izingxenye ezi-3 ~ 6 zikawoyela omhlophe, izingxenye eziyi-1 ~ 2 ze-stearic acid, izingxenye eziyi-1 ~ 2 zamafutha a-silicone we-hydroxyl kanye nezingxenye ezingama-20 ~ 30 ze-polyethylene noma i-polypropylene zinyakaze ngokulinganayo ngemuva kokusebenza, ekushiseni okungu-150 ~ 190 ℃, ngokusebenzisa parallel twin screw extruder extrusion yayo exubile kanye granulating.
Ukuze kuhlanganiswe usayizi we-masterbatch futhi kuncishiswe imfucuza nothuli enqubweni yokukhiqiza, i-masterbatch iyasikwa futhi ihlolwe ngomoya ukuze kutholwe usayizi wezinhlayiyana ezifanayo.
I-ejenti yokuhlanganisa i-ejenti yokuhlanganisa ye-titanate noma i-ejenti yokuhlanganisa i-aluminate noma i-ejenti yokuhlanganisa ye-silane.
