Nyob rau hauv tus txheej txheem ntawm kev siv kub yaj nplaum nplaum, vim muaj kev hloov ntawm ntau yam xwm txheej, peb yuav ntsib ntau yam teeb meem. Txhawm rau daws cov teeb meem no, peb yuav tsum muaj kev nkag siab zoo thiab kev tshuaj xyuas zoo ntawm ntau yam. Niaj hnub no, Qingdao sainuo polyethylene wax chaw tsim tshuaj paus yuav coj koj los nkag siab txog cov teeb meem cuam tshuam thiab cov kev daws teeb meem ntawm cov nplaum nplaum kub rau ntug sealing.

pe ciab rau kub yaj nplaum

Tshawb xyuas los ntawm qhov ntsuas kub (substrate kub, roj hmab tank, roj hmab txheej rau cov menyuam kub, ambient kub), av noo (ib puag ncig, phaj), thickness (ntug banding siv, kua nplaum txheej), ceev (qhib, kho, pub), nto ( txiav qhov tseeb, roughness), siab (loj thiab kev taw qhia), mechanical force (txiav quab yuam loj thiab kev taw qhia), thiab tom qab ntawd ua cov kev soj ntsuam tshwj xeeb raws li cov teeb meem tshwj xeeb: 1. Tso tawm tom qab kev sib txuas (1) Lub substandard melamine foob hauv qab tso tawm cov khoom uas ua rau degumming

(2) Tsis tsim nyog PVC ntug sealing primer yog incompatible nrog kub yaj nplaum

(3) Oily ntoo veneer ntug sib txuas nrog incompatible kub yaj nplaum

(4) Thaum cov ntoo veneer ntug sealing yog siv los ua primer, qhov feem ntawm Tianna dej los yog lwm yam diluent yog loj heev, thiab cov diluent muaj zog heev, ua rau expansion ntawm kub yaj nplaum nplaum, thiab ces cov nplaum nplaum sealing yuav loosen. tom qab kev sib raug zoo.

(5) Qhov laj thawj yog vim li cas cov nplaum nplaum kub yaj yog txias thaum lub sij hawm sib koom ua ke (ntse txias). Cov kev sib txuas ruaj khov (xws li kub, siab, ua haujlwm ceev, thiab lwm yam) yuav tsum tau tswj xyuas, txwv tsis pub cov txiaj ntsig sib txuas kuj tseem cuam tshuam.

Qhov ua rau ntawm cov nplaum txias (sudden txias) yog raws li hauv qab no:

(1) Nyob rau hauv cov txheej txheem ntawm kev sib txuas, lub sij hawm cua sov ntawm kub yaj nplaum yog luv luv, yog li ntawd qhov kub ntawm cov nplaum nplaum kub tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.

(2) Lub teeb kub ntawm cov nplaum nplaum kub yog tsawg dhau.

(3) Cov kua nplaum tsis txaus.

(4) Qhov ntsuas kub tsawg dhau thaum ua haujlwm lossis ntawm qhov chaw tsim kho.

(5) Lub substrate kub yog tsawg dhau.

2. Yuav muaj "kav hlau" thaum gluing

(1) Qhov kub thiab txias los ntawm lub tshuab gluing yog tsawg dhau

(2) Kub yaj nplaum tau deteriorated ua ntej siv

(3) Cov txheej txheem gluing tsis raug thiab txoj kev (ntau dhau gluing)

(4) Qhov kub sib txawv ntawm sab nraum zoov thiab sab hauv tsev (qhov chaw tsim kho) yog qhov loj, thiab cov cua convection yog ib qho yooj yim los hloov qhov kub thiab txias (tshwj xeeb tshaj yog nyob rau lub caij ntuj no)

3. Muaj av lossis nplaum ntau dhau ntawm ntug

(1) Cov kua nplaum ntau dhau

(2) Mechanical tsis ua hauj lwm nyob rau hauv cov txheej txheem trimming

(3) Txoj haujlwm gluing tsis raug

(4) Lub teeb kub ntawm lub tshav kub yaj yog siab dhau

4. Lub tshuab gluing muaj tsis txaus los yog tsis sib xws

(1) Muaj kev thaiv cov kua nplaum nyob rau hauv cov txheej txheem ntawm pre melting los yog ntawm qhov tawm ntawm lub tshuab gluing, uas yuav ua rau tsis sib xws gluing

(2) Lub peev xwm ua haujlwm ntawm lub tshuab tsis txaus los yaj cov nplaum tag

(3) Qhov kub thiab txias ntawm cov cua kub yaj yog qis heev

5. Muaj pa luam yeeb lossis tsw ntxhiab

(1) Lub teeb kub yog siab dhau

(2) Cov cuab yeej siv tshuab tam sim no tsis raug

(3) Muaj ib yam dab tsi tsis ncaj ncees lawm nrog lub ntsuas sov ntawm lub tshuab gluing

(4) Muaj ib yam dab tsi tsis ncaj ncees lawm ntawm lub rhaub

(5) Lub melter kub tsis huv thiab tov nrog lwm yam impurities los yog hmoov av

6. Kev hloov pauv loj ntawm cov nplaum kub yaj

(1) Nws yog qias neeg thiab tsim oxidation

(2) Cov khoom deterioration tom qab cua sov lossis kub kub

(3) Lub melter kub ua haujlwm ntev tsis muaj ntug banding

7. Ntug banding yog ib qho yooj yim kom poob thaum lub sij hawm trimming txheej txheem

(1) Cov kua nplaum yog nyias heev

(2) Cov khoom txias dhau los yog ntub dej (tshwj xeeb tshaj yog thaum tsuas yog glued)

(3) Yog tias cov kab gluing kom meej meej qhia cov qauv ntawm cov menyuam gluing, nws yuav yog qhov kub ntawm cov menyuam gluing tsawg dhau.

(4) Siv ceev ceev heev

(5) ambient kub lossis khoom kub tsawg dhau (hauv qab 15 ° kev ua haujlwm)

(6) Tsis muaj siab

8. Qhov chaw pib thiab chaw nres tsheb ntawm ntug sealing tsis zoo tagnrho

(1) Cov menyuam cov menyuam yuav tsum paub cov txuj ci los hloov kho, txuas ntxiv txoj haujlwm los ua kom cov menyuam siab.

(2) Cov nyhuv feem ntau tsis zoo thaum pib lossis qhov kawg ntawm 5cm txoj hauj lwm ntawm cov nplaum nplaum ntawm cov menyuam nplaum. Yog vim li cas yog tias lub siab ntawm cov nplaum nplaum yog ib qho yooj yim kom tsis txaus ntawm lub taub hau thiab tus Tsov tus tw txoj hauj lwm, thiab thaum nws yog nyob rau hauv lub high-ceev ntau lawm lub xeev, kev sib cuag ntawm lub glued cov menyuam thiab lub vaj huam sib luag yog ib qho yooj yim mus dhia.

9. Cov txiaj ntsig ntawm kev sib txuas ntawm ob sab yog qhov zoo ntawm ib sab thiab qhov tsis zoo ntawm lwm tus

(1) Kev sib cuag tsis zoo ntawm vaj huam sib luag (substrate) thiab cov menyuam

(2) Tsis sib xws gluing ua rau cov kua nplaum tawm, uas cuam tshuam cov txheej txheem kev sib khi

10. Qee zaum cov kua nplaum yog qhov zoo thiab qee zaum nws tsis zoo

(1) Cov kua hauv lub xeev kub ntawm cov nplaum nplaum kub yog tsawg dhau

(2) Thaum qhov kev hloov ceev ntawm ntug banding tshuab nrawm dhau thiab cov kua nplaum ntau dhau, lub tank kub yaj tsis yaj cov kua nplaum kub yaj hauv lub sijhawm, ua rau cov kua nplaum tsis sib xws.

(3) Qhov kub ntawm lub fuser tsis ruaj khov.

11. Tom qab kev sib txuas, cov ntug banding yuav raug sib cais sai sai

(1) Kub yaj nplaum nplaum, ntug, substrate, cargo los yog siab rau cov menyuam kub siab heev

(2) Qhov kub ntawm kev tsim kho ib puag ncig (chav kub) siab dhau lawm

(3) Cov kua nplaum ntau dhau

(4) High humidity ntawm ntug lossis substrate

(5) Cov khoom siv hauv paus thiab ntug sealing nws tus kheej muaj cov khoom siv cob (roj), yog li txo qhov adhesion, uas feem ntau tshwm sim hauv cov txheej txheem ntawm kev siv ntoo veneer / khoom ntoo ntug sealing

12. Muaj cov cim paj rau ntawm qhov chaw sib khi 1) Cov khoom siv ntug yog nyias dhau lawm thiab qhov chaw ua haujlwm tsis muaj zog 2) Lub qhov rooj ntawm ib sab yog ntxhib 3) Cov nplaum nplaum tsis muaj elasticity.
