Polyurethane nplaum nplaum

5. Kev siv:

(1) pretreatment: qhov saum npoo ntawm cov nplaum yog ntxuav.

(2) sizing: siv sawtooth scraper siv cov kua nplaum rau saum npoo ntawm cov nplaum sib npaug, kuj tuaj yeem siv cov txheej txheem dov, tsis tuaj yeem siv txhuam txhuam (cov kua nplaum viscosity loj), txhuam tus nqi ntawm 250g / m2, tshwj xeeb raws li qhov teeb meem tiag tiag tswj cov kua nplaum.

(3) composite: tom qab cov kua nplaum tuaj yeem ua cov nplaum nplaum.

(4) tom qab kev kho mob: vim tias cov kua nplaum no yog cov nplaum nplaum nplaum, thaum cov nplaum txheej tau kho, cov kua nplaum tuaj yeem raug drilled rau hauv micro qhov ntawm cov nplaum, ua lub luag haujlwm ntawm kev thauj mus los, ua kom lub zog sib txuas, thiab yuav tsum tau compressed. tom qab kho.

Nws muaj cov yam ntxwv ntawm kev ua tau zoo tshaj, kev tsim kho yooj yim, foaming tom qab kho, insolubility thiab insolubility, siab thiab kub tsis kam.

Scope ntawm daim ntawv thov

Kev tsim cov qhov rooj hluav taws kub, lub qhov rooj tiv thaiv tub sab, lub qhov rooj hauv tsev, cov khoom siv txias, thiab ntau yam khoom siv hluav taws kub thiab thermal rwb thaiv tsev (pob zeb wool, ceramic wool, ultra-fine iav ntaub plaub, polystyrene ua npuas ncauj yas, thiab lwm yam) kuj siv. rau kev sib raug zoo.Rau hlau rau hlau adhesion.

Cov lus qhia

1. Lub hauv paus ntsiab lus ntawm kev kho: Cov nplaum no yog ib qho khoom hnyav-dawb nplaum nplaum, uas yog kho los ntawm cov dej noo absorbed hauv huab cua thiab ntawm qhov chaw ntawm adherend.

2.Surface kho ntawm adherend: tshem tawm cov roj thiab hmoov av ntawm qhov chaw ntawm adherend.Cov roj ntau dhau tuaj yeem ntxuav nrog acetone lossis xylene.Yog tias tsis muaj roj stain, nws tsis tsim nyog los ntxuav.Lub sij hawm, yog tias tsim nyog, tshuaj tsuag me me ntawm cov dej pos huab ntawm cov roj hmab saum npoo nrog lub sprayer.

3.Glue txheej: Siv lub zigzag scraper kom sib npaug siv cov kua nplaum rau ntawm qhov chaw adherend.Cov kua nplaum siv tshuab kuj tuaj yeem siv tau, tab sis tsis tas yuav txhuam hniav (cov roj viscosity loj), thiab cov txheej txheem yog li 150-250g /㎡.Qhov saum npoo ntawm qhov adherend tuaj yeem txo qis me ntsis, thiab qhov roughness ntawm qhov chaw tuaj yeem nce me ntsis, uas yog, ntev npaum li qhov chaw ntawm ob qhov adherends tau ntsib thiab tuaj yeem tiv taus cov kua nplaum tag, qhov tsawg dua cov txheej txheej, qhov zoo dua, vim tias qhov sib txawv ntawm qhov adherends tuaj yeem txo qis me ntsis. ntau cov kua nplaum yog siv, qhov ntau Cov dej noo absorbed ntawm qhov chaw ntawm adherend yog txwv, uas yuav cuam tshuam rau lub sijhawm kho.Yog tias yuav tsum tau siv cov kua nplaum, ib qho me me ntawm cov dej pos huab tuaj yeem raug txau kom tsim nyog.

4.compound: tuaj yeem ua kua nplaum

5.Post-kev kho mob: Vim lub foaming nplaum ntawm cov roj hmab no, thaum cov nplaum txheej yog kho, cov kua nplaum tuaj yeem laum cov micropores ntawm adherend, uas plays lub luag hauj lwm anchoring thiab tsub kom lub zog sib txuas.Cov khoom yog compacted thiab tuaj yeem loosened tom qab kho (lub siab yog li 0.5kg-1kg / cm2).

6.Tool ntxuav siv tau ethyl acetate hnyav.

Cov kev ceev faj

1 、 Siv serrated spatula rau lub scraper, xws li lub phaj tiaj tus.Txawm li cas los xij, yog tias cov kua nplaum tau siv zog heev, yuav tsis muaj kua nplaum nyob rau ntawm txheej txheej.Yog tias cov kua nplaum yog siv heev, cov kua nplaum yuav pov tseg ntau dhau.Lub zigzag scraper yog ib qho nyuaj li nws yog, thiab cov kua nplaum sab laug los ntawm sawtooth yog ntau npaum li cas.

2 、 Ob qhov chaw sib txuas ua ke yuav tsum tau muab khi rau ntawm ib sab.

txoj kev cia

Cov khoom no yuav tsum tau muab cia rau hauv qhov chaw txias thiab tsaus thaum khaws cia.Feem ntau nyob rau hauv tsev warehouses, lub sij hawm cia yog ib xyoos.Tom qab txhua qhov kev siv cov kua nplaum, lub thoob nrog cov kua nplaum ntau dhau yuav tsum tau muab kaw thiab khaws cia, thiab cov kua nplaum sab saud yuav ua kom khov thiab ua kom tawv nqaij vim muaj kev cuam tshuam ntawm cov dej noo.Yog tias nws tsis siv sijhawm ntev, nws yuav tsum tau ntim nrog nitrogen.
