Umhlahlandlela Wokucubungula Ukubumba Umjovo we-HDPE: Kusukela ku-Resin kuya ku-Finished Part

Inhlanganisela ye-HDPE ukumelana namakhemikhali futhi ukumelana nomthelela kwenza kube kuhle kakhulu emathangini kaphethiloli, emathileyi ezokwelapha, nasezitsheni zokudla. Kodwa-ke, ukufeza izingxenye ezibunjiwe ezisezingeni eliphezulu kudinga ukulawulwa okunembile kwezigaba ezintathu ezibalulekile. Nasi umhlahlandlela omsulwa osekelwe eminyakeni eyi-15 yesipiliyoni ensimini.

Isigaba 1: Ukulungiselela Izinto

1. Ukukhethwa kwe-Resin

● Ukudla/Ibanga Lezokwelapha: Cacisa amamaki ahambisana ne-FDA (isb., i-ExxonMobil HD7705)

● IzimboniSebenzisa ama-resin aqiniswe yi-UV (isb., i-Chevron HDPE 5502) ekusetshenzisweni kwangaphandle

2. Iphrothokholi Yokomisa

● Izinga lokushisa: 65-80°C (149-176°F)

● Isikhathi: amahora angu-2-3 (okubalulekile—i-HDPE engakavuthwa ibangela amabhamuza kanye nemigqa yokushisela ebuthaka)

● Umswakama Ohlosiwe:

Ithiphu Yochwepheshe: Gcina izikhwama ze-resin ezivuliwe ezitsheni ezivaliwe ezine-desiccant.

Isigaba 2: Izilungiselelo Zomshini

(Izinga lokushisa eliphansi + isivinini esisheshayo = izimpawu zokugeleza; Izinga lokushisa eliphezulu + ingcindezi esheshayo = izindawo ezibushelelezi)

Isigaba 3: Izinto Ezibalulekile Zokuklama Isikhunta

1. Ubukhulu Bodonga

● Ubuncane: 1.5mm (0.059")

● Okufanelekile: 2.5-3.5mm (0.098-0.138")

● 6mm? Sebenzisa ukubumba okusiza ngegesi ukuvimbela isinki

2. Isinxephezelo Sokuncipha

Okujwayelekile: 1.5-4% (kuyahlukahluka ngokwebanga)

3. Umklamo Wesango

● Amasango aqondile ezingxenye ezijiyile (>4mm)

Ukuxazulula Izinkinga: Izinkinga Ezi-3 Ezibucayi Kakhulu

Inkinga 1: Ukusonta

● Imbangela Eyinhloko: Amazinga okupholisa angalingani

● Ukulungiswa:

Khulisa izinga lokushisa lesikhunta libe ngu-50°C+

Engeza iziteshi zokupholisa ezivumelanayo (ukunciphisa isikhathi somjikelezo esingu-5-15%)

Inkinga 2: Imigqa Yokushisela E-Brittle

● Kungani: Izinto ziphola ngokushesha kakhulu ezindaweni zokuhlanganisa

● Izixazululo:

Khuphula izinga lokushisa lokuncibilika ngo-10-15°C

Shintsha amasango ukuze unciphise ukuhlangana kwemingcele yokugeleza

Inkinga 3: Ukunamathela Esikhumbeni

● Uhlu Lokuhlola:

Isikhunta esipholishiwe kuya ekugcineni kwe-SPI-A3 (Ra ≤0.2μm)

Faka ukukhululwa kwesikhunta (isb., i-PTFE spray) njalo ngemijikelezo engu-500

Qinisekisa ama-engeli okusalungiswa: okungenani okungu-1° (2° ezindaweni ezithambile)

Ukuthatha Okubalulekile:

Ukuguquguquka kwe-HDPE kuvulwa ngokucubungula okuhlelekile. Lawula izinsika ezintathu—ukoma kwezinto, amazinga okushisa anembile, kanye nomklamo wesikhunta oqaphela ukuncishiswa—ukugwema izinkinga zokukhiqiza ezingama-80%. Kumaphrojekthi ayinkimbinkimbi, sebenzisana nochwepheshe bamathuluzi abaqonda ukuthi ukwakheka kwe-HDPE kuthinta kanjani ukusebenza kwengxenye yokugcina.
