Raws li cov khoom siv sib xyaw ua ke uas sib xyaw ua ke ntawm elasticity ntawm npuas nrog kev ntxhib los mos ntawm cov ntaub, cov txheej txheem ntawm daim txhuam cev cov ntaub npog ntau theem, suav nrog cov khoom siv raw, ua npuas ncauj molding, ntaub lamination, thiab tiav.
Kev tsim khoom pib nrog raw khoom formulation thiab pretreatment. Cov txheej ua npuas dej feem ntau siv siab - cov ntaub ntawv molecular xws li polyurethane lossis polyvinyl cawv. Cov polymer matrix, foaming tus neeg sawv cev, catalyst, thiab additives yog sib tov tusyees raws li cov qauv los ua ib tug foaming raw khoom nrog haum flowability. Cov ntaub saum npoo yog tsim los ntawm paj rwb, polyester, nylon, lossis lawv cov xov paj sib xyaw, xaiv raws li cov khoom muag. Nws tau dhau los ua warping, sizing, thiab weaving txheej txheem los tsim cov ntaub grey, thiab ua ntej - kev kho mob yog ua raws li qhov xav tau los tshem tawm kev ntxhov siab sab hauv thiab ua kom muaj kev ruaj ntseg. The key point at this stage is the strict control of raw material quality, especially ensuring that the foaming ratio and viscosity of the foam raw material match the designed density and pore size, while the fabric must achieve the expected weight and warp and weft strength.
Tom qab ntawd cov txheej txheem ua npuas ncauj molding pib. Cov txheej txheem foaming muaj xws li molding foaming thiab nruam foaming. Moulding foaming yuav tsum tau txhaj cov khoom sib xyaw ua ke rau hauv cov pwm ua ntej - zoo li tus pwm, cua sov kom nthuav dav thiab ua kom cov khoom ruaj khov, tsim ua npuas ncauj ntawm cov thickness thiab contour. Nruam foaming siv lub tshuab foaming kom tusyees extrude raw cov ntaub ntawv mus rau ib tug tsiv conveyor siv, qhov uas lawv kho nyob rau hauv ib tug kom qhuav qhov los ua ib tug ntev yob ntawm cov khoom ua npuas ncauj. Kev tswj xyuas meej ntawm cov txheej txheem tsis yog qhov tseem ceeb; Txawm tias me ntsis kev hloov pauv hauv qhov kub thiab txias, siab, thiab lub sijhawm tshuaj tiv thaiv tuaj yeem cuam tshuam rau qhov sib xws ntawm cov qauv ntawm tes thiab kev ua haujlwm.
Qhov thib peb kauj ruam yog lamination ntawm ua npuas ncauj nrog ntaub. Nyob ntawm cov khoom tsim nyog, kev sib txuas, kub nias, lossis cov txheej txheem stitching tuaj yeem xaiv. Kev sib khi ua ke nrog cov npuas dej thiab cov ntaub, siv cov nplaum rau ib puag ncig, thiab tom qab ntawd siv txawm tias lub siab nrog cov chais los xyuas kom muaj kev sib raug zoo. Kub nias ua rau cov npuas dej me ntsis yaj nyob rau hauv qhov kub thiab txias, interlocking nrog cov ntaub fibers, haum rau cov khoom uas yuav tsum tau siab breathability. Stitching siv rab koob xuas nrig ntaus los yog lub tshuab stitching rau mechanically entangle cov ntaub thiab ua npuas ncauj, txhim kho interlayer bonding thiab imparting ib tug tshwj xeeb zoo nkauj. Thaum lub sij hawm lamination txheej txheem, lub siab tis thiab mus ncig ceev yuav tsum tau tswj kom tsis txhob muaj ntau tshaj ua npuas ncauj compression los yog ntaub wrinkling, kom ntseeg tau tias uniform composite txheej thickness thiab ib tug du tsos.
Tom qab lamination, cov theem tiav pib. Cov theem no muaj xws li nto embossing, laser perforation, txheej kho, thiab txiav thiab shaping. Embossing thiab perforation optimize huab cua permeability thiab elasticity tis, thaum txhim kho cov hniav zoo nkauj; tshuaj tua kab mob, tiv thaiv-mildew, lossis nplaim taws- cov coatings retardant muab cov haujlwm tshwj xeeb rau cov khoom siv los ntawm padding lossis txau, kom ntseeg tau tias kev nkag mus rau cov khoom siv ntxiv yam tsis muaj kev cuam tshuam ua npuas dej; txiav thiab shaping yog ua raws li cov khoom tiav specifications siv riam txias los yog kub, thiab cov npoo yog trimmed los tiv thaiv fraying.
Thaum kawg, kev tshuaj xyuas zoo thiab ntim khoom yog ua tiav. Inspection items cover foam density, compression resilience, interlayer peel strength, air permeability, and surface defects. Cov khoom tsim nyog tau muab tais, dov, los yog daim ntawv- ntim raws li kev txiav txim siab, nrog rau cov dej noo thiab plua plav tiv thaiv kom ruaj khov thaum khaws cia thiab thauj mus los.
Hauv cov ntsiab lus, cov txheej txheem tsim cov ntaub txhuam cev tsom rau kev tsim cov khoom siv raw, ruaj khov ua npuas ncauj molding, muaj zog thiab txhim khu kev qha, thiab tom qab- ua haujlwm nthuav dav. Los ntawm kev tswj kom zoo thiab kev ua kom zoo tshaj plaws nyob rau hauv tag nrho cov txheej txheem, sib sib zog nqus sib sib zog nqus ntawm cov ntaub ntawv kev ua tau zoo thiab qhov kawg - cov neeg siv cov kev xav tau yog tiav, muab lub hauv paus tsim khoom rau nws daim ntawv thov dav.
