Tili ndi antchito athu ogulitsa zinthu, gulu lathu la akatswiri, gulu la akatswiri, ogwira ntchito ku QC ndi ogwira ntchito yopereka ma phukusi. Tsopano tili ndi njira zoyendetsera bwino kwambiri pa njira iliyonse.

Mapaipi a PPR

Poyerekeza ndi mapaipi achitsulo, mapaipi a PPR ali ndi ubwino wokhazikitsa mosavuta, kutchinjiriza bwino kutentha, komanso kukana dzimbiri. Ndi chinthu chopatsa madzi chabwino komanso chosawononga chilengedwe ndipo ndi chinthu chodziwika bwino chopereka madzi pamsika. Mapaipi a PPR amapezeka makamaka mumitundu iyi, yoyera, yaimvi, yobiriwira ndi ya curry, chifukwa chake pali kusiyana kumeneku makamaka chifukwa cha mitundu yosiyanasiyana ya masterbatches yomwe yawonjezeredwa.

Kuwonjezera pa makhalidwe a mapaipi apulasitiki monga kulemera kopepuka, kukana dzimbiri, kusakulitsa, ndi moyo wautali wautumiki, mapaipi a PP-R alinso ndi makhalidwe akuluakulu awa:

1 Sizowopsa komanso zaukhondo.
Mamolekyu a PP-R ndi zinthu za kaboni ndi haidrojeni zokha, ndipo palibe zinthu zovulaza komanso zoopsa. Ndi zaukhondo komanso zodalirika. Sizimagwiritsidwa ntchito popaipi yamadzi ozizira ndi otentha okha, komanso popaipi yamadzi akumwa oyera.

2 Kusunga kutentha ndi kusunga mphamvu.
Mphamvu ya kutentha ya chitoliro cha PP-R ndi 0.21w/mk, yomwe ndi 1/200 yokha ya chitoliro chachitsulo.

3 Kukana kutentha bwino.
Malo ofewetsa a Vicat a chitoliro cha PP-R ndi 131.5℃. Kutentha kwakukulu kogwirira ntchito kumatha kufika 95℃, komwe kungakwaniritse zofunikira za dongosolo la madzi otentha mu code yoperekera madzi ndi madzi otuluka m'nyumba.

4 Utumiki wautali.
Pansi pa kutentha kwa ntchito kwa 70℃ ndi kuthamanga kwa ntchito (PN) kwa 1.0MPa, moyo wa ntchito wa chitoliro cha PP-R ukhoza kufika zaka zoposa 50 (bola ngati zipangizo za chitolirocho ziyenera kukhala S3.2 ndi S2.5 kapena kuposerapo); pansi pa kutentha kwabwinobwino (20℃) moyo wa ntchito ukhoza kufika zaka zoposa 100.

5 Kukhazikitsa kosavuta komanso kulumikizana kodalirika.
PP-R ili ndi ntchito yabwino yolumikiza mapaipi ndi zolumikizira. Mapaipi ndi zolumikizira zimatha kulumikizidwa ndi kusungunuka kotentha ndi electrofusion. Kukhazikitsa kwake ndikosavuta ndipo zolumikizira zake ndi zodalirika. Mphamvu ya cholumikizira ndi yayikulu kuposa mphamvu ya chitolirocho.

Zipangizo 6 zitha kubwezeretsedwanso.
Zinyalala za PP-R zimatsukidwa, kusweka, ndikubwezerezedwanso kuti zigwiritsidwe ntchito popanga mapaipi ndi zolumikizira. Kuchuluka kwa zinthu zobwezerezedwanso sikupitirira 10% ya kuchuluka konse ndipo sikukhudza ubwino wa chinthucho.

kukhazikitsa

Tili ndi antchito athu ogulitsa zinthu, gulu lathu la akatswiri, gulu la akatswiri, ogwira ntchito ku QC komanso ogwira ntchito yokonza zinthu. Tsopano tili ndi njira zoyendetsera bwino kwambiri pa njira iliyonse. Komanso, antchito athu onse ali ndi luso losindikiza nkhani ya ODM Factory China Ammonia Refrigerant Gas Powered Stop Valve, Tikukhulupirira kuti tingakhale ndi ubale wabwino ndi amalonda ochokera padziko lonse lapansi.
ODM Factory China Danfoss Stop Valve, Hansen Stop Valve, Tikuyesetsa kuti tigwirizane ndi zomwe zikuchitika padziko lonse lapansi, nthawi zonse tidzayesetsa kukwaniritsa zomwe makasitomala akufuna. Ngati mukufuna kupanga njira zina zatsopano, tikhoza kuzisintha nokha. Ngati mukufuna chilichonse mwa zinthu zathu kapena mukufuna kupanga njira zatsopano, onetsetsani kuti muli omasuka kulankhula nafe. Tikuyembekezera kupanga ubale wabwino ndi makasitomala padziko lonse lapansi.
