Thermosetting hmoov txheej thiab thermoplastic hmoov txheej

Hmoov txheej yog ib hom txheej uas yog siv los ua cov dej tsis muaj dej, cov hmoov qhuav. Qhov sib txawv tseem ceeb ntawm cov xim ua kua thiab cov hmoov txheej yog tias cov hmoov txheej tsis tas yuav muaj cov kuab tshuaj los ua kom cov binder thiab muab tub lim rau hauv daim ntawv ua kua. Cov txheej txheej feem ntau yog siv electrostatically thiab tom qab ntawd kho hauv qab cua sov kom nws ntws thiab tsim "daim tawv nqaij". Cov khoom siv raw yog literally hmoov, sib tov qhuav, extruded, thiab hauv av rau hauv cov khoom kawg.Ib puag ncig kev nyab xeeb txheej uas tuaj yeem muab ntau yam kev ua tiav zoo ua rau hmoov lwm txoj hauv kev nyab xeeb ecologically rhiab heev uas peb nyob niaj hnub no.

Cov hmoov yuav yog a thermoplastic los yog thermoset polymer. Nws yog feem ntau yog siv los tsim ib qho tawv tiav uas yog tawv dua li cov xim pleev xim. Hmoov txheej yog siv rau txheej hlau, xws li cov khoom siv hauv tsev, aluminium extrusion, thiab cov tsheb thiab tsheb kauj vab. Cov thev naus laus zis tshiab tso cai rau lwm cov ntaub ntawv, xws li MDF (nruab nrab-density fiberboard), ua hmoov coated siv ntau txoj kev.

Thermoplastic hmoov txheej tsis chemically react nyob rau hauv ib tug kho theem. Lawv feem ntau yog siv rau kev ua haujlwm thiab siv hauv cov yeeb yaj kiab tuab, feem ntau 6-12 mils. Lawv siv rau ntau yam kev siv uas yuav tsum tau ua kom tiav nrog kev cuam tshuam thiab / lossis tshuaj lom neeg.

Thermosetting hmoov txheej yog thov thiab tom qab ntawd kho hauv qhov cub ntawm qhov kub thiab txias rau qee lub sijhawm. Cov txheej txheem kho yuav ua rau muaj tshuaj lom neeg crosslinking los ua qhov chaw, hloov cov hmoov mus rau hauv cov yeeb yaj kiab tas mus li uas yuav tsis remelt.Lawv yog siv rau ntau yam kev ua haujlwm thiab kev zoo nkauj thiab feem ntau siv rau hauv cov yeeb yaj kiab nyias, feem ntau hauv cov yeeb yaj kiab thickness ntawm 1.5 mus rau 4 miv.
