kusinthidwa masterbatch kwa high kachulukidwe polyethylene mvukuto ndi awiri lalikulu,
HDPE kwa apa, HDPE kwa curragated chitoliro,

Izi zimapangidwa pogwiritsa ntchito ukadaulo wa UNIPOL™.Amapangidwa kuti agwiritsidwe ntchito popanga mapaipi pomwe mphamvu yanthawi yayitali ya hydrostatic ndi kukana kufalikira kwapang'onopang'ono kumafunidwa.Ntchito zoyenera zikuphatikiza mapaipi ogawa gasi, mipope yayikulu yamafakitale, migodi, zimbudzi, ndi mizere yoperekera madzi mumsewu.Kugwirizana kwa Miyezo ya Industrial: ASTM D 3350: gulu la maselo - Natural - PE345464A - Black - PE345464C (Onani MFUNDO A) Plastics Pipe Institute (PPI): TR-4 - Natural Pipe - DGDB-2480 NT 3408 - ASTM PE3608 chitoliro cha HDsi giredi 0p @ 73°F – Black Pipe – DGDB-2480 BK 3408 (Onani MFUNDO B) — ASTM PE3608 kalasi ya chitoliro – 1600psi HDB @ 73°F ndi 800psi HDB @ 140°F National Sanitation Foundation (NSF) Standard 14 ndi 61 – Natural Pipe – DGDB-2480 NT 3608 – Black Pipe – DGDB-2480 BK 3608 (Onani MFUNDO B) Onani malamulowa kuti mumve zambiri.ZINDIKIRANI: (A) Nambala zisanu zoyambirira za gulu la maselo zimatengera utomoni wachilengedwe.Nambala yomaliza ndi chilembo zimachokera ku utomoni wakuda (utomoni wachilengedwe kuphatikiza 6.5% DFNF-0092).(B) Natural resin extruded pansi pamikhalidwe yoyenera ndi carbon black masterbatch DFNF-0092 (6.5%).

Zithunzi za HDPEmvuto, wotchedwa PE curragted chitoliro, ndi mtundu watsopano wa chitoliro kuwala opangidwa ndi mkulu kachulukidwe polyethylene.It ali makhalidwe a kulemera kuwala, kukana kuthamanga, kulimba bwino, kumanga mwamsanga ndi moyo wautali.

The awiri a HDPE mivuvu iwiri khoma opangidwa ku China ndi φ400 ~ φ1400mm, amene osati amafuna mkulu fluidity wa zipangizo kukwaniritsa zofunika kukonza zida, komanso amakwaniritsa zofunika mphete stiffness kalasi ya mankhwala (S2 kalasi yaikulu kuposa 8KN /m2, pazinthu zina, kukula kwake kwakukulu, kutsika kwa mtengo wa mpheteyo.Choncho izi zimabweretsa vuto linalake posankha zipangizo.Pambuyo poyesera kangapo, Qilu HDPE2480 ikhoza kukwaniritsa zofunikira zake zopanga, koma kuuma kwa mphete. mankhwala sangathe kufika 8KN / m2. Kuuma kwa mphete kuyesedwa kwamtengo wapatali pa kutentha kwapakati (23 ± 2 ℃) ndi 6.2kN / m2, zomwe zimafuna kusinthidwa kwa zinthu ndipo zimafuna kuti popanda kuchepetsa ntchito ya HDPE2480 yoyambirira. Pansi pakuwonetsetsa kusinthasintha kwa mphete, kutentha kochepa komanso mphamvu yamphamvu ya chinthucho; Sinthani modulus yopindika yazinthu kuti zitsimikizire kuuma kwazinthu.
Njira yopangira kudzaza kwakukulu kosinthidwa kwa masterbatch amivuto yayikulu kwambiri ya polyethylene yomwe imatha kukwaniritsa zofunikira za kusinthasintha kwa mphete zazikulu, kutsika kwa kutentha, mphamvu ya notch komanso kupindika kwina.
Kusakaniza ndi 30-50% D50 = 2-7 ​​μm ultrafine calcium carbonate ndi 50-70% ultrafine talc powder, ufa wophatikizika unakonzedwa.
Kudzaza kwazinthu zosinthidwa zopangidwa ndi zinthu zaufa zophatikizika zimatha kufika 50% mumivundi yayikulu ya HDPE.Pansi pa HDPE∶ zida zatsopano zosinthidwa = 50∶50, kulemera kwa chitoliro chokhala ndi mawonekedwe omwewo kumangowonjezera 5 ~ 6%, ndipo modulus yake yopindika imafika 1360Mpa.The wamakokedwe ndi zotsatira kukana zinthu ndi mphamvu flexural wa 24Mpa n'zofanana ndi wa zinthu choyambirira kusinthidwa pamene wodzazidwa ndi 30%: mphamvu kumakokedwa ndi ≥24Mpa, ndi kuphulika chiwerengero cha zitsanzo 10 ndi kukana zimakhudza pa 0 ℃ ndi zosakwana 1, zomwe zimakwaniritsa zofunikira zamtundu waukulu wa HDPE.
Amagwiritsa ntchito 30 ~ 50% D50 = 2 ~ 7μm superfine calcium carbonate ndi 50 ~ 70% superfine talc ufa kusakaniza mu 100-part composite ufa, kuwonjezera 0.2 ~ 1 gawo kugwirizana wothandizila mu gulu ufa ndi oyambitsa kwa mphindi 5 ~ 10 pa 120 ~ 140 ℃.Kenako onjezani magawo 3-6 a mafuta oyera, 1 ~ 2 magawo a stearic acid, 1 ~ 2 magawo amafuta a silikoni a hydroxyl ndi magawo 20 ~ 30 a polyethylene kapena polypropylene akuyambitsanso chimodzimodzi pambuyo pa zinthuzo, kutentha kwa 150 ~ 190 ℃ parallel twin screw extruder extrusion yake yosakanikirana ndi granulating.
Pofuna kugwirizanitsa kukula kwa masterbatch ndikuchepetsa zinyalala ndi fumbi popanga, masterbatch imadulidwa ndikuwonetseredwa ndi mpweya kuti ipeze kukula kwa tinthu komweko.
Cholumikizira ndi titanate coupling agent kapena aluminate coupling agent kapena silane coupling agent.
