Tili ndi gulu lathu lopeza phindu, gulu lopanga mapulani, gulu laukadaulo, gulu la QC ndi gulu lopereka ma phukusi. Tsopano tili ndi njira zabwino zogwirira ntchito pa ntchito iliyonse. Komanso, antchito athu onse ali ndi luso losindikiza nkhani za2 inchi White Thupi PVC Mpira Valavu, Mtundu Watsopano Wa China Wolimba Kwambiri Wabwino Kwambiri Kuthamanga, Timaika patsogolo ubwino wa malonda ndi ubwino wa makasitomala. Amalonda athu odziwa bwino ntchito amapereka chithandizo mwachangu komanso moyenera. Gulu lowongolera ubwino limaonetsetsa kuti zinthu zili bwino kwambiri. Timakhulupirira kuti ubwino umachokera mwatsatanetsatane. Ngati mukufuna, tiyeni tigwire ntchito limodzi kuti tipambane.

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 gulu lathu lopeza phindu, gulu lopanga ndi kupanga zinthu, gulu laukadaulo, gulu la QC ndi gulu logwira ntchito yokonza zinthu. Tsopano tili ndi njira zabwino zogwirira ntchito pa ntchito iliyonse. Komanso, antchito athu onse ali ndi luso losindikiza mutu wa Wholesale Discount China DIN ASTM ISO Standard PVC Compact Ball Valve, Zipangizo zolondola zoyendetsera ntchito, Zipangizo Zopangira Injection Molding, mzere wopangira zida, ma lab ndi chitukuko cha mapulogalamu ndi zinthu zomwe zimatisiyanitsa.
Kuchotsera Kwambiri Mtundu Watsopano Wa China Wokhazikika Kwambiri Kupanikizika Kwabwino Kwambiri, Valavu ya Mpira wa PVC Yoyera ya mainchesi awiri, Timayika ubwino wa malonda ndi zabwino za makasitomala pamalo oyamba. Amalonda athu odziwa bwino ntchito amapereka chithandizo mwachangu komanso moyenera. Gulu lowongolera khalidwe limatsimikiza kuti khalidwe labwino kwambiri. Timakhulupirira kuti khalidwe limachokera mwatsatanetsatane. Ngati mukufuna, tiyeni tigwire ntchito limodzi kuti tipambane.
