Polypropylene ntawv: hom thiab specifications

Niaj hnub nimno tsev thiab finishing ntaub ntawv muaj sufficiently zoo yam ntxwv uas cia los tsim ntau yam complex khoom. Yog li ib daim ntawv thiab polypropylene. Nws yog siv nyob rau hauv ntau qhov chaw ntawm tib neeg kev ua si. Yog li ntawd nws yuav siv tau nyob rau hauv cov tsev neeg los yog lag luam.

Yuav ua li cas yog cov ntaub ntawv uas?

Polypropylene ntawv - ib tug hluavtaws tsev ntaub uas muaj zoo heev lub zog, raws li zoo raws li ib tug loj tus naj npawb ntawm zoo. Yog li ntawd, tus sawv cev ntawm cov khoom yog nyob rau hauv coob ob leeg nyob rau hauv tsev thiab loj-scale siv.

Muaj tej hom ntawm cov khoom, uas muaj ntau zog. Cov koj yuav xav txog rau yav tom ntej. Thaum lub sij hawm lawm los xij rau raw cov ntaub ntawv no ntxiv rau cov sib txawv tshuaj Cheebtsam uas yuav ua tau kom lub cev thaj chaw ntawm cov khoom.

khoom Specifications

Polypropylene ntawv muaj zoo zog uas ua rau nws ib tug nrov:

1. Melting point - 165 degrees.

2. Kuj mus te - mus txog rau 10 mus.

3. Ceev - 0.92 g / cc.

4. elasticity - 1.15 N / hli square.

5. Thermal conductivity - 0,22 W / m * K.

Tom ntej no, peb tig mus rau rau lo lus nug ntawm yog dab tsi zoo tau xa cov khoom.

khoom pab cuam

Polypropylene ntawv muaj cov nram qab zoo:

- Dav ntau ntawm cov xim thiab ntxoov. Tsis tas li ntawd, daim ntawv tej zaum yuav opaque los yog pob tshab. Hais tias yog, koj muaj lub peev xwm los ua ib tug ntau yam ntawm decorations.

- tsawg kub stability, txhoj puab heev tshuaj, hnav, te.

- Muaj peev xwm mus kom qhov zoo.

- High zog, nyob rau lub Daim ntawv no saj zawg zog nyob rau hauv ib tug txias lub xeev. Lawm, nyob rau hauv thiaj li yuav zoo dua txais qhov tsim nyog daim ntawv no, nws yuav ua tau ib tug me ntsis rhuab.

- Ib qho yooj yim tu thiab tuav. Qhov no cov ntaub ntawv uas yog ib qho yooj yim mus txiav, chais plaub. Nyob rau hauv cov ntaub ntawv no, koj yuav tsis nkim ib tug ntau ntawm hmoov av. Txiav cov khoom koj ua tau thiab li, thiab ib tug jigsaw.

- High thermal conductivity.

- Tsawg dej permeability.

- tus phooj ywg environmentally. Txawm nyob rau hauv tus txheej txheem ntawm ub cov khoom hais tsis paug rau ib puag ncig.

- Tsawg ceeb thawj.

- Cov khoom suab tsis ua hluav taws xob tam sim no.

Polypropylene ntawv (nws tus yam ntxwv koj twb paub) - nws yeej demanded ib yam khoom uas tso cai rau koj kom paub lub boldest architectural tswv yim.

Liaj teb ntawm daim ntawv thov

Tam sim no peb yuav tsum xav txog yog vim li cas lug siv cov khoom no.

1. Nyob rau hauv cov zaub mov kev lag luam: rau zus tau tej cov ntim, uas tom qab yog fej kua (mis nyuj, dej) los yog cov khoom.

2. Nyob rau hauv cov tshuaj kev lag luam: rau zus tau tej cov ntim, uas yuav tsum tau khaws cia txig txhoj puab heev tshuaj (alkali acid).

3. Nyob rau hauv lub chaw ua hauj lwm: los ntawm nws ua phau ntawv npog, phau ntawv sau, folders thiab hnab ntawv.

4. Nyob rau hauv kev tsim kho: tiled pas dej da, kev siv ntawm lub hauv paus formwork. Nyob rau hauv tas li ntawd, qhov no cov ntaub ntawv uas yog tsim rau cov kev siv ntawm cov dej thiab tshav kub mov systems.

5. Nyob rau hauv horticulture: polypropylene ua zoo heev pots thiab ntim rau seedlings.

6. Nyob rau hauv tas li ntawd, qhov no cov ntaub ntawv uas ua zoo los rau da thiab saunas.

Feem ntau, cov polypropylene ntawv, cov kev yam ntxwv uas yog tau piav nyob rau hauv tsab xov xwm, siv zoo qhov txhia chaw.

ntau yam ntawm cov khoom

Nws yuav tsum tau muab sau tseg tias hom ntawm cov khoom tsis yog li ntawd ntau npaum li cas. Muaj ib co hom polypropylene:

- kaw ntom nti. Los ntawm nws feem ntau manufactured ntim los yog lwm yam khoom uas tus nruj yog ib qho tseem ceeb. Feem ntau siv rau polypropylene ntawv xws dej.

- Cellular. Nws yog siv raws li ib tug ntim khoom, raws li zoo raws li nyob rau hauv kev tsim kho.

- Polystyrene. Nws yog feem ntau siv raws li ib tug rwb thaiv tsev ntaub.

Xav txog qhov tseeb style ntxiv.

nta ua npuas ncauj

Niaj hnub no nws yog tshwm sim heev. Lub fact tias cov khoom muaj zoo heev zog: zoo rau absorbing suab thiab kev co, cuab tsiaj thaum tshav kub kub. Tsis tas li ntawd, cov khoom tsis tshuam nqus dej, txawm nws muaj qhov ntxeem tau qauv. Nws yog lub teeb heev, ces nws yuav siv tau rau thermal rwb thaiv tsev, tsis tsuas ib leeg-storey tsev, tab sis kuj cov high-rises.

Ntau foamed polypropylene ntawv heev weakly illuminated. Nyob rau hauv cov ntaub ntawv no, cov huab cua tsis tsim tej yam tshuaj lom. Nws yog heev yooj yim mus ua hauj lwm. Nws yuav kav kom txog 20 xyoo.

Nws yog siv lug sawv cev yam khoom: rau thermal rwb thaiv tsev ntawm phab ntsa ntawm lub tsev sab nraum ntawm nyuaj panels. Nws tw hauv lub phab ntsa rau zoo nrov haum. Txij li thaum cov khoom tsis nqus dej, nws yuav ntsia tau rau hauv qhov chaw nyob qhov twg muaj siab av noo. Thiab nws siv package ib tug ntau yam ntawm lub cev tsis kho cov khoom.

Properties Machining khoom

Brazing ntawv ntawm polypropylene - ib tug neeg ua hauj lwm tsis nyuaj heev. Ntxiv mus, tag nrho cov kev ua yog ua sai sai txaus. Nws yog ib qho tseem ceeb uas yuav tau xav kom zoo machining ntawm cov khoom. Yog li ntawd:

1. lub cuab tam uas yuav tau ua, yuav tsum tau zoo sharpened.

2. Tus nto ntawv yuav tsum npog xwb ntug ntawm cov hniav. Nyob rau hauv cov ntaub ntawv no, tej no yuav muaj ntau muaj tseeb.

3. Thaum lub sij hawm kev lag luam, koj yuav tau xyuas kom meej lub purity ntawm cov khoom. Uas yog, cov hniav grinders yuav tsum tseg freed los ntawm shavings.

4. Thiab tseem xav tau kom paub tseeb tias lub cuab tam yog txias nyob rau hauv lub sij hawm. Nws yog tsim nyog nyob rau hauv thiaj li tsis mus yaj cov npoo ntawm cov kev txiav.

Ntau hom vuam khoom

Yog li ntawd, mus cuag lub ntsiab rau txhua lwm yam nyob rau hauv peb txoj kev:

- Polifuzionnaya welded polypropylene ntawv. Nws yog suav hais tias yog feem ntau pom zoo thiab kev zoo. Rau cov khoom ntawm lub chaw ua hauj lwm peb yuav tsum tau ib tug tshwj xeeb ntaus ntawv uas yuav sov lub npoo ntawm cov ntawv txheeb rau cov uas yuav tsum tau kub. Ntxiv mus, lawv yog ntseeg tau nias tiv thaiv txhua lwm yam. Tom qab txias, lub leeg yog check heev. Yog li thov xws li ib tug txoj kev rau lub tebchaw yuav ua tau tej ntaub ntawv uas hais txog ntawm nws cov thickness.

- Vuam nrog lub extruder. Mus nqa tawm kev ua hauj lwm uas koj xav tau ntxiv hlau khoom. Nws yuav tsum tau nco ntsoov hais tias hais tias ib tug compound ntawm xws li ib tug lub cuab tam yog ua li cas manually. Lawm, nyob rau hauv cov ntaub ntawv no ib tug heev high degree ntawm lub zog yog tsis tsim nyog rau kev cia siab. Nyob rau hauv Feem ntau, ib tug extruder yog siv thaum nws yog tsim nyog los koom los xij ntawm loj thickness.

- Vuam nrog ib tug tshwj xeeb phom, tso cai huab cua kub. Ntawm no, ib yam nkaus thiab, peb yuav tsum tau ib tug tshwj xeeb vuam ceg me. Txawm li cas los, tus ntaus ntawv yog tsis tau muaj ib tug siab huab cua kub yog qhov. Qhov no qhia tias cov leeg yuav tau deb tsawg tshaj meej. Lawm, lub soldering ntawm tuab daim polypropylene nyob rau hauv cov ntaub ntawv no tej zaum yuav tsis muab suav hais tias. Cov phom yog tsuas yog tsis txaus kom sov li lub leeg zoo.

Tus heev txheej txheem ntawm vuam yuav tsum tau nqa tawm ua tib zoo txaus. Xav txog qhov zoo ntawm cov ceg me. Piv txwv li, yog hais tias nws yog refractory, tus quab yuam ntawm nias rab phom mus rau lub weld qab. Rau tsevneeg yog ib tug zoo, yuav tsum zoo sov li lub cuab tam thiab tej koom haum. Lawm, lub kub yuav tsum niaj hnub zoo li.

Nyob rau hauv thiaj li yuav effect soldering, lub phaj yuav tsum tau txuas mus rau txhua lwm yam. Ua li no, koj yuav thov tau cov clamp. Yog hais tias qhov no txoj kev ua no yog ib qhov nyuaj, ces muaj yog ib txoj kev: smetyvanie nrog ib tug tshwj xeeb tuag tsim rau txoj kev ua no.

Tom qab kawm tiav ntawm lub chaw ua hauj lwm yuav tsum tau them nyiaj mloog mus rau lub purity ntawm lub leeg. Lawm, thaum lub sij hawm Vuam nws zoo nkaus li ua npuas ncauj uas hardens. Nyob rau hauv hauv paus ntsiab lus, yog hais tias nws tsis pom, lub leeg tsis muaj ko. Txawm li cas los, nws yuav ntxuav koj. Ua li no, siv ib tug ntse riam thiab txiav uas ntau heev. Nco ntsoov hais tias qhov no yuav tsum tau ua tib zoo thiaj li tsis mus disturb tus ntseeg ntawm tus nto ntawm lub phaj.

Hais tias yog tag nrho cov nta ntawm ib daim ntawv ntawm polypropylene. Tam sim no koj paub yuav ua li cas nws yuav tsum tau ua licas thiab yog dab tsi cov khoom nws muaj.
