Yuav tswj cov hardness ntawm High Pressure Laminate Xovxwm Kab li cas

Nyob rau hauv High Pressure Laminate Xovxwm Kab, kev tswj cov khoom hardness yog qhov txuas tseem ceeb, uas muaj ntau yam.
1. Cov khoom siv raw
Resin hom thiab zoo: Resin yog ib qho ntawm cov khoom tseem ceeb uas txiav txim siab qhov hardness ntawm cov khoom. Resins nrog siab hardness thiab siab cross-linking ceev, xws li phenolic resin, yog nyiam. Nws cov qauv molecular tuaj yeem tsim qhov ruaj khov thiab muaj zog peb-seem network tom qab kho, uas tuaj yeem muab cov khoom muaj zog dua li urea-formaldehyde resin. Nyob rau tib lub sijhawm, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm
Cov khoom siv txhawb zog ntxiv: Cov ntaub ntawv siv fiber ntau, xws li iav fiber ntau, tuaj yeem tsim nyog ntxiv rau daim ntawv impregnated. Cov fibers no tuaj yeem sib npaug sib npaug hauv lub laminate thaum lub sij hawm nias, thiab ua hauj lwm ua ke nrog cov resin los txhim kho tag nrho cov hardness thiab lub zog ntawm cov khoom. Tus nqi ntxiv yuav tsum tau txiav txim siab los ntawm kev sim ua raws li qhov yuav tsum tau ua ntawm hardness ntawm cov khoom, thiab feem ntau tswj tau ntawm qhov sib piv loj ntawm 5% - 15%.
2. Nias txheej txheem tsis
Kev tswj siab: Lub siab ncaj qha cuam tshuam rau qhov hardness ntawm cov khoom. Tsis pub dhau qhov kev tso cai los ntawm cov cuab yeej siv, tsim nyog nce lub siab tuaj yeem ua rau cov ntawv impregnated txheej nruj sib xyaw ua ke, ua rau cov resin ua kom zoo dua cov pores thiab ua kom cov tawv tawv.
Kev tswj ntsuas kub: Qhov ntsuas kub uas tsim nyog tuaj yeem ua kom cov resin curing cov tshuaj tiv thaiv thiab txhim kho cov hardness. Cov resins sib txawv muaj lawv qhov kub zoo tshaj plaws, xws li phenolic resin ntawm 150-180 degree . Siv cov ntsuas kub thiab ntsuas cua sov kom paub meej tias qhov kub ntawm cov ntawv xovxwm kub yog qhov ruaj khov nyob rau hauv qhov tsim nyog kom tsis txhob muaj qhov tsis sib xws los ntawm qhov kub thiab txias.
Nias lub sij hawm teem: txaus lub sij hawm nias yuav xyuas kom meej tias cov resin yog tag nrho kho. Yog tias lub sijhawm luv luv, cov resin yuav tsis kho tag nrho thiab lub hardness yuav tsis txaus; Yog tias lub sijhawm ntev dhau lawm, nws yuav cuam tshuam rau kev tsim khoom. Kev txiav txim siab raws li cov khoom tuab thiab cov khoom siv kho cov yam ntxwv, xws li rau cov laminates thicker lossis qeeb-reacting resins, lub sijhawm nias tuaj yeem txuas ntxiv kom tsim nyog. Feem ntau, lub sij hawm nias tuaj yeem nce los ntawm 2-3 feeb rau txhua txhua 2 hli nce hauv thickness.
3. Tom qab ua tiav
Cov khoom nias tuaj yeem ua tiav tom qab ua tiav. Piv txwv li, qhov kub thiab txias nyob rau lub sij hawm ntev kev kho mob theem nrab tuaj yeem nce qib ntawm resin cross-linking, yog li ua kom lub zog ntawm cov khoom, tab sis nws yog ib qho tsim nyog los tswj cov kev ua haujlwm kom tsis txhob muaj cov khoom deformation lossis lwm yam teeb meem zoo. .
