Kuj nug, koj puas tuaj yeem txuas polyethylene rau polypropylene?
Polypropylene ( PP ) thiab Polyethylene (PE) yuav tsis yog vuam . Yog koj sim ua vuam ob cov ntaub ntawv, qib ntawm cov yas nrog ib tug qis melting kub thiab siab viscosity yuav yaj thiab ntws hla ntawm qhov chaw ntawm lwm yam khoom.
Ib yam li ntawd, koj ua li cas weld polyethylene? Vuam Polyethylene
- Kauj Ruam 1 - Kho qhov kev puas tsuaj. Ua ntej koj ua dab tsi, ntxuav cov yas nrog xab npum thiab dej thiab cia nws qhuav.
- Kauj Ruam 2 - Qhuav hauv V-groove. Siv koj cov lus kub welder, yaj hauv v-groove raws qhov tawg ntawm ib nrab ntawm cov yas.
- Kauj Ruam 3 - Melt hauv Vuam pas nrig.
- Kauj Ruam 4 - Qhuav hauv Kev Txhim Kho Mesh.
Tsis tas li ntawd, qhov kub ntawm polypropylene yaj yog dab tsi?
160 ° C
Dab tsi yuav lo rau polyethylene?
Lub Loctite All-Plastic Super Glue suav nrog lub raj ntawm kev sib txuas tus neeg sawv cev thiab lub raj mis ntawm qhov chaw ua haujlwm. Nws ua ke nrog yas thiab tawv yas. Cov kua nplaum ua haujlwm zoo nrog polyethylene thiab polypropylene nto.

Lub tuam txhab muaj peev xwm ua kom tau raws li cov neeg siv khoom xav tau raws sijhawm yog hu ua Kev Ua Haujlwm Zoo, thaum ua haujlwm tau zoo yog lub tuam txhab muaj peev xwm xa khoom raws li tus neeg siv khoom xav tau nrog tsawg kawg ntawm cov khoom siv raw, kev ua haujlwm thiab tus nqi
Dab tsi yog qhov txawv ntawm qhov point thiab nonpoint qhov chaw ntawm dej paug?
Piv txwv li, cov dej tso tawm los ntawm cov chaw tsim khoom lag luam ntawm qee yam lossis cov chaw kho dej khib nyiab. Cov chaw uas tsis yog cov ntsiab lus suav nrog kev khiav tawm ntawm thaj av ua liaj ua teb uas tuaj yeem ntxuav cov chiv lossis lwm yam tshuaj rau hauv pas dej lossis dej ntws - qhov no yuav tshwm sim ntau txhiab square kilometers
Dab tsi txaus ntshai zoo kawg li nws yog qhov peb yuav tsum tau khawb trenches thiab sim cov roj npog qhov ncauj qhov ntswg ntawm no vim muaj kev sib cav nyob hauv lub tebchaws nyob deb ntawm cov neeg uas peb tsis paub dab tsi?
Qhov txaus ntshai npaum li cas, zoo heev, zoo kawg yog tias peb yuav tsum tau khawb trenches thiab sim roj-qhov ncauj qhov ntswg ntawm no vim muaj kev sib cav nyob rau hauv ib lub teb chaws nyob deb ntawm cov neeg uas peb tsis paub dab tsi.

Dab tsi kub koj vuam polyethylene?
Lwm yam tshaj li kev ua kom koj qhov ntom ntom tau sib xws, polyethylene yog ib qho yooj yim zoo nkauj rau vuam. Txhawm rau vuam LDPE koj yuav tsum muaj qhov kub thiab txias ntawm kwv yees li 518 ° F / 270 ° C, lub regulator teem ntawm kwv yees li 5-1 / 4 txog 5-1 / 2 thiab rheostat ntawm 5. Zoo li PP, HDPE yog weldable ntawm 572 ° F / 300 °C
Dab tsi yog qhov txawv ntawm qhov cuam tshuam qhov (socket) thiab lub qhov (socket) pa?
Rau kuv qhov kev paub qhov sib txawv yog nqes mus rau cov khoom siv Qhov saum npoo-hardening ua rau muaj kev cuam tshuam cov qhov (socket) kom nqus tau qhov hloov pauv tam sim ntawd (aka 'kev cuam tshuam') zoo dua. Nrog rau kev cuam tshuam txaus txaus, lub qhov (socket) tsis tu ncua tuaj yeem tawm ntawm cov duab vim tias cov hlau siv muaj softer
