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

Zipangizo zoyendetsedwa bwino, gulu la akatswiri ogulitsa, ndi ntchito zabwino zogulitsa pambuyo pogulitsa; Ndife banja lalikulu logwirizana, aliyense amatsatira mfundo ya kampani ya "kugwirizana, kudzipereka, kulekerera" pamtengo wokwanira wa valavu ya mpira wa pulasitiki wakuda waku China wa UPVC Pipe Fittings, Tikukhulupirira kuti tidzakhazikitsa ubale wabwino ndi inu posachedwa. Tidzakudziwitsani za kupita patsogolo kwathu ndipo tikuyembekezera kumanga ubale wabwino ndi inu.
Mtengo woyenera wa valavu ya mpira wa pulasitiki yaku China, valavu ya mpira wa PP, Monga antchito ophunzira bwino, opanga zinthu zatsopano komanso amphamvu, tili ndi udindo pazinthu zonse za kafukufuku, kapangidwe, kupanga, kugulitsa ndi kugawa. Pophunzira ndikupanga njira zatsopano, sitikutsatira kokha komanso tikutsogolera makampani opanga mafashoni. Timamvetsera mwatcheru mayankho ochokera kwa makasitomala athu ndikupereka kulumikizana mwachangu. Mudzamva nthawi yomweyo ukatswiri wathu komanso ntchito yathu yosamala.
