1. Tsis zoo nto gloss
Pwm tsis zoo, plua plav nto, thiab lwm yam.
Cov ntsiab lus curing tsawg, tsis tiav kev kho, tsis muaj kev kho kom zoo, tsis kho tom qab.
Tsawg ambient kub, siab ambient humidity.
Lub gel txheej txheej tsis kho tag nrho ua ntej demolding.
High muab tub lim nyob rau hauv gelcoat, tsis tshua muaj collective resin ntsiab lus.
2. Wrinkles ntawm qhov chaw ntawm cov khoom
Wrinkles rau gelcoat yog cov kab mob uas tshwm sim, vim li cas cov gelcoat rau kev kho tag nrho yog prematurely them nrog resin, thiab styrene kom ib feem ntawm cov gelcoat yog yaj, o thiab wrinkles. Cov kev kho mob hauv qab no muaj:
Xyuas seb lub thickness ntawm cov gelcoat puas yog raws li tus nqi teev (0.3-0.5mm, 400-500 g/m2), yog tias tsim nyog, tuaj yeem ua kom tuab tuab.
Tshawb xyuas cov resin kev ua haujlwm.
Tshawb xyuas cov hardener ntxiv thiab qhov sib xyaw ua ke.
Xyuas seb qhov sib ntxiv ntawm cov xim puas cuam tshuam rau kev kho ntawm cov resin.
Ua kom qhov chaw ua haujlwm kub nce mus rau 18-20 degree .
3. Pinholes tshwm rau saum npoo tom qab kho thaum cov pa npuas me me lurk hauv lub tsho gel. Plua plav rau saum npoo ntawm pwm tuaj yeem ua rau pinholes. Kev kho mob yog raws li nram no.
Ntxuav lub ntsej muag ntawm cov pwm thiab tshem tawm cov plua plav.
Tshawb xyuas cov viscosity ntawm cov resin, yog tias tsim nyog, siv styrene los dilute nws dua, los yog txo cov thixotropic tus neeg sawv cev.
Yog tias cov pwm tso tawm tsis raug xaiv kom raug, nws yuav ua rau cov ntub dej tsis zoo thiab cov pinholes, thiab cov pwm tso tawm tus neeg sawv cev yuav tsum tau kuaj xyuas. Qhov no tsis tshwm sim nrog polyethylene.
Tsis txhob sib tov cua thaum ntxiv hardener thiab pigment paste.
Txheeb xyuas qhov nrawm ntawm rab phom. Yog hais tias cov tshuaj tsuag ceev heev, pinholes yuav tshwm sim.
Xyuas lub atomizing siab thiab tsis txhob ua kom nws siab dhau.
Tshawb xyuas cov qauv resin. Ntau dhau hardener yuav ua rau pre-gel thiab latent cua npuas.
Tshawb xyuas qib thiab hom methyl ethyl ketone peroxide lossis cyclohexanone peroxide.
