iimveliso

i-masterbatch elungisiweyo yoxinaniso oluphezulu lwemivumbo yepolyethylene enobubanzi obukhulu,
HDPE ukuba ngezantsi, I-HDPE yombhobho ojikelezileyo,

Le mveliso iveliswa kusetyenziswa ubuchwepheshe benkqubo yeUNIPOL™.Yenzelwe ukusetyenziswa kwizicelo zemibhobho apho amandla exesha elide e-hydrostatic kunye nokuchasana nokukhula okucothayo kokuqhekeka kunqweneleka.Usetyenziso olufanelekileyo lubandakanya imibhobho yokuhambisa irhasi yendalo, imibhobho yoshishino edayamitha enkulu, imigodi, ilindle, kunye neentambo zenkonzo zamanzi zikamasipala.Ukuthotyelwa kweMigangatho yoShishino: ASTM D 3350: ukuhlelwa kweeseli – kwendalo – PE345464A – Mnyama – PE345464C (Jonga AMANQAKU A) Iziko lePlastiki lemibhobho (PPI): TR-4 – iNdalo yombhobho – DGDB-2480 NT 3408 — ASTM PE3608 HDsi umbhobho 0p @ 73°F – uMbhobho omnyama – DGDB-2480 BK 3408 (Jonga AMANQAKU B) — ASTM PE3608 ibakala lombhobho – 1600psi HDB @ 73°F kunye 800psi HDB @ 140°F National Sanitation Foundation (NSF) Standard 14 kunye 61 – Natural Pipe – DGDB-2480 NT 3608 – Black Pipe – DGDB-2480 BK 3608 (Jonga AMANQAKU B) Qhagamshelana nemigaqo ngeenkcukacha ezipheleleyo.AMANQAKU: (A) Amanani amahlanu okuqala okuhlelwa kweeseli asekelwe kwintlaka yendalo.Inombolo yokugqibela kunye neleta zisekelwe kwi-resin emnyama (i-resin yendalo kunye ne-6.5% DFNF-0092).(B) I-resin yendalo ekhutshwe phantsi kweemeko ezifanelekileyo kunye ne-carbon black masterbatch DFNF-0092 (6.5%).

HDPEI-Bellows, eyaziwa ngokuba yi-PE curragted pipe, luhlobo olutsha lombhobho okhanyayo owenziwe nge-polyethylene ephezulu yoxinaniso.

Ububanzi bemivumbo ephindwe kabini yodonga lwe-HDPE eveliswe eTshayina yi-φ400 ~ φ1400mm, engadingi nje kuphela ubumanzi obuphezulu bezinto zokuhlangabezana neemfuno zokusetyenzwa kwezixhobo, kodwa ikwahlangabezana neemfuno zebakala lokuqina kweringi yeemveliso (iklasi ye-S2 inkulu kune-8KN /m2, kwimathiriyeli ethile, ubukhulu bedayamitha, isezantsi ixabiso lokuqina kweringi.Ngoko oku kuzisa ubunzima obuthile ekukhetheni izinto.Emva kovavanyo oluninzi, iQilu HDPE2480 inokuhlangabezana neemfuno zayo zokuvelisa, kodwa ukuqina komsesane imveliso ayikwazi ukufikelela kwi-8KN / m2. Ixabiso lokuvavanya ukuqina kwekhonkco kwiqondo lokushisa eliqhelekileyo (23±2℃) yi-6.2kN / m2, efuna ukuguqulwa kwezinto kwaye ifuna ukuba ngaphandle kokunciphisa ukusebenza kwe-HDPE2480 yasekuqaleni. phantsi kobume bokuqinisekisa ukuguquguquka kweringi, ifuthe eliphantsi lobushushu kunye nenotshi yempembelelo yokuqina kwemveliso;
Inkqubo yokwenziwa kokuzaliswa okuphezulu kwe-masterbatch ephuculweyo ye-caliber ephezulu yoxinaniso lwe-polyethylene bellows enokuthi ihlangabezane neemfuno ze-caliber enkulu ye-bellows ring flexibility, ifuthe eliphantsi lobushushu, amandla empembelelo yenotshi kunye nokufa okuthile kokugoba.
Ixutywe ne-30-50% D50 = 2-7 ​​μm i-ultrafine calcium carbonate kunye ne-50-70% ye-ultrafine talc powder, i-powder composite yalungiswa.
Isixa sokuzaliswa kwezinto eziphambili ezilungisiweyo ezenziwe ngezinto ezidibeneyo ze powder zingafikelela kwi-50% kwi-HDPE i-bellows enkulu-diameter.Ngaphantsi kwemeko ye-HDPE∶ entsha elungisiweyo ye-master material = 50∶50, ubunzima bombhobho kunye ne-caliber efanayo banda kuphela i-5 ~ 6%, kunye ne-modulus yayo yokugoba ukuya kwi-1360Mpa.Ukunyanzeliswa kunye nokuchasana kwempembelelo yezinto ezinamandla okuguquguqukayo kwe-24Mpa kufana neyokuqala kwezinto eziguquliweyo xa zizaliswe nge-30%: amandla okuqina ngu-≥24Mpa, kunye nenani lokukrazula kweesampuli ze-10 kunye nokuxhatshazwa kwempembelelo kwi-0℃ ingaphantsi kwe-1, ehlangabezana ngokupheleleyo neemfuno zomgangatho wemivumbo emikhulu ye-HDPE.
Isebenzisa 30 ~ 50% D50 = 2 ~ 7μm superfine calcium carbonate kunye 50 ~ 70% superfine talc umgubo ukuxuba 100-inxalenye yomgubo oyintlanganisela, wongeza 0.2 ~ 1 inxalenye yokudibanisa agent kwi-powder composite kwaye ushukumisa imizuzu 5 ~ 10 at. 120 ~ 140℃.Emva koko yongeza i-3 ~ 6 iinxalenye zeoli emhlophe, i-1 ~ 2 iinxalenye ze-stearic acid, i-1 ~ 2 iinxalenye zeoli ye-silicone ye-hydroxyl kunye ne-20 ~ 30 iinxalenye ze-polyethylene okanye i-polypropylene ivuselela ngokulinganayo emva kwezinto, kwi-150 ~ 190 ℃ ubushushu, ngokusebenzisa parallel twin screw extruder extrusion yayo exubeneyo kunye negranulating.
Ukuze udibanise ubungakanani be-masterbatch kunye nokunciphisa inkunkuma kunye nothuli kwinkqubo yokuvelisa, i-masterbatch inqunywe kwaye ihlolwe ngomoya ukuze ifumane ubungakanani obufanayo.
I-arhente yokudibanisa yi-agent edibanisa i-titanate okanye i-alumine coupling agent okanye i-silane coupling agent.
