Dab tsi txiav txim siab qhov ruaj khov ntawm Edge Banding

PVC ntug banding yog cov khoom siv thermoplastic yob feem ntau yog ua los ntawm polyvinyl chloride, nrog rau kev sib ntxiv ntawm cov yas yas, stabilizers, lubricants, dyes thiab lwm yam additives, tov thiab dov ua ke. Nws tuaj yeem kaw qhov ntu ntu ntawm cov rooj tog kom tsis txhob muaj kev puas tsuaj los ntawm ib puag ncig lossis kev siv yam tseem ceeb (feem ntau yog ya raws), tiv thaiv formaldehyde volatilization hauv lub rooj tsavxwm, thiab tseem ua tiav cov teebmeem zoo nkauj.
Qee cov neeg siv khoom siv PVC ntug banding, tab sis vim qhov tsis txaus ntawm qhov ruaj khov, qhov khoob yuav tshwm sim thaum lub rooj tog zaum ntug banding, ua rau lub detachment ntawm ntug banding. Dongguan Decoration Materials Co., Ltd. tam sim no qhia rau koj txog qhov cuam tshuam rau qhov ruaj khov ntawm PVC ntug banding:
(1) Los ntawm qhov pom ntawm qhov ntsuas kub, qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov ruaj khov ntawm PVC ntug banding tsis tseem ceeb. Lub shrinkage tus nqi ntawm PVC ntug banding nce nrog qhov nce ntawm qhov kub thiab txias: qhov shrinkage tus nqi ua ntej ntug banding nce sai thiab linearly tom qab 60 degree, thaum lub shrinkage tus nqi tom qab ntug banding qhia cov qauv no tom qab 70 degree. Xav tias qhov kub siab siv tas li ntawm PVC yog nyob nruab nrab ntawm 65 degree thiab 85 degree, qhov kev sim ntsuas kub yog teem rau ntawm 65 degree.
(2) Los ntawm qhov kev xav ntawm lub sijhawm, lub sijhawm muaj kev cuam tshuam loj rau qhov ruaj khov ntawm PVC ntug banding. Lub shrinkage tus nqi ntawm PVC ntug banding nce nrog lub sij hawm. Ntawm 65 degree, qhov shrinkage tus nqi ua ntej ntug sealing zoo li stabilize tom qab 4 teev, thiab tus nqi shrinkage tom qab ntug sealing zoo li stabilize tom qab 5 teev. Rau qhov yooj yim ntawm kev sim, lub sijhawm sim yog teem rau 4 teev.
(3) Los ntawm qhov kev xav ntawm cov av noo, qhov cuam tshuam ntawm kev sib khi ntawm ntug banding yog qhov tsis txaus ntseeg. Lub shrinkage tus nqi ntawm ntug banding sawb tom qab ntug banding txo nyob rau hauv high humidity tej yam kev mob. Yog vim li cas rau qhov kev txo qis no tshwm sim vim yog kev hloov pauv ntawm qhov loj ntawm lub substrate nyob rau hauv qhov kev coj rov qab. Qhov laj thawj tshwj xeeb rau kev hloov pauv yog qhov kev ntxhov siab ntawm cov substrate, nplaum, thiab ntug banding strip
(4) Los ntawm qhov pom ntawm qhov sib txawv ntawm qhov kub thiab txias, qhov tshwm sim ntawm qhov txias thiab kub mus rau qhov ruaj khov ntawm PVC ntug banding tsis tseem ceeb. Lub shrinkage tus nqi ntawm PVC ntug banding uas tau overheated tseem tsis tau hloov nyob rau hauv qis kub tej yam kev mob; Thaum lub caij caij tsheb kauj vab, nws tau ua kom sov tas li, thiab txawm hais tias nws tseem nyob ntawm qhov kub thiab txias, vim yog lub sijhawm cuam tshuam ntawm lub sijhawm, nws qhov shrinkage tus nqi tseem nce, tab sis qhov nce tsis tseem ceeb.
(5) From the perspective of the raw materials used for edge banding, this factor has a significant impact on the dimensional stability of plastic edge banding. The shrinkage rate comparison of the three types of plastic edge banding is PVC>ABS>PP, qhia tias PP muaj qhov ruaj khov zoo, ua raws li ABS, thiab PVC tsis zoo, vim muaj qhov sib txawv ntawm qhov sib txawv ntawm peb.
(6) Los ntawm kev xav ntawm cov cuab yeej tsim khoom, peb yam ntawm kev ua cov txheej txheem, cov khoom siv, cov ntaub ntawv raw, thiab cov khoom ntim khoom muaj qhov cuam tshuam loj rau qhov ruaj khov ntawm PVC ntug banding. Ntawm lawv, cov ntug banding tau los ntawm dov muaj qhov ruaj khov zoo dua li cov ntug banding tau los ntawm extrusion; Qhov loj stability ntawm ntug banding extruded los ntawm ntxaib-ntsia hlau hmoov yog zoo dua li ntawm ntug banding extruded los ntawm ib tug ntsia hlau pellets; Lub shrinkage tus nqi ntawm Ay cov khoom yog qis dua li ntawm A + cov ntaub ntawv, uas txhais tau hais tias cov ntug banding nrog ntau calcium carbonate cov ntsiab lus muaj kev ruaj ntseg zoo dua li cov ntug banding nrog tsawg calcium carbonate cov ntsiab lus.
(7) Los ntawm kev xav ntawm ntug sealing tshuab, ob yam ntawm board substrate thiab kub yaj nplaum tsis muaj kev cuam tshuam loj rau qhov ruaj khov ntawm PVC ntug sealing strips. Ntawm lawv, lub shrinkage tus nqi ntawm ntug banding nrog nruab nrab fiber board raws li lub substrate yog qis dua li nrog particleboard raws li lub substrate, thiab qhov sib txawv maj mam nce nrog qhov kub thiab txias. Lub ntsiab yog vim li cas tej zaum yuav yog cov qauv ntawm ob hom khoom vaj khoom tsev sib txawv. Particle board muaj cov khoom loj thiab ntau qhov khoob, thaum nruab nrab fiberboard muaj cov khoom me me thiab cov qauv nruj. Cov qauv sib txawv no yuav muaj qhov sib txawv ntawm qhov sib txawv ntawm cov nplaum kub yaj, ua rau qhov xwm txheej no.
Cov saum toj no yog cov yam ntxwv uas cuam tshuam qhov kev ruaj ntseg ntawm PVC ntug banding, thiab ib qho tseem ceeb yog qhov zoo ntawm PVC ntug banding. Qhov zoo dua qhov zoo ntawm PVC ntug banding, qhov ruaj khov dua tus nqi shrinkage.
