Tshawb nrhiav cov khoom siv thiab cov qauv ntawm cov yeeb yaj kiab tiv thaiv

Aluminium tiv thaiv zaj duab xis yog ib qho qauv ntawm polyethylene (PE) zaj duab xis raws li lub substrate, polyacrylic acid (ester) resin ua cov khoom tseem ceeb ntawm lub siab-rhiab nplaum nplaum, ua ke nrog ntau cov nplaum tshwj xeeb los ntawm txheej, txiav, ntim, thiab lwm yam txheej txheem, Kev tiv thaiv zaj duab xis yog mos, nrog lub zog nplaum zoo, yooj yim rau paste, yooj yim rau tev. Lub siab-rhiab nplaum nplaum ruaj khov yog qhov zoo thiab yuav tsis cuam tshuam rau qhov khoom ntawm qhov chaw raug pasted.

Scope ntawm daim ntawv thov: Feem ntau yog siv rau txhua yam yas, ntoo phaj (daim ntawv) tiv thaiv nto, xws li PVC, PET, PC, PMMA ob-xim phaj, ua npuas ncauj board UV board, iav, thiab lwm yam phaj nto hauv kev thauj mus los, cia. , thiab kev ua haujlwm, cov txheej txheem installation tsis muaj kev puas tsuaj.

Cov qauv thiab cov khoom siv ntawm cov yeeb yaj kiab tiv thaiv

Cov yeeb yaj kiab tiv thaiv feem ntau yog polyacrylate tiv thaiv zaj duab xis, polyacrylate tiv thaiv zaj duab xis ntawm cov qauv yooj yim los ntawm sab saum toj mus rau hauv qab: txheej txheej, txheej luam ntawv, zaj duab xis, txheej nplaum.

(1, txheej cais; 2, txheej luam ntawv; 3, zaj duab xis; 4, txheej nplaum)

1. Zaj duab xis

Raws li cov ntaub ntawv raw, zaj duab xis feem ntau yog ua los ntawm cov polyethylene (PE) thiab polyvinyl chloride (PVC). Extrusion molding, txhaj tshuaj molding, thiab tshuab moulding tuaj yeem tau txais. Raws li polyethylene yog pheej yig dua thiab ntau tus phooj ywg ib puag ncig, 90% ntawm cov yeeb yaj kiab yog ua los ntawm polyethylene, nrog cov txheej txheem tshuab moulding ua lub ntsiab lus tseem ceeb. Muaj ntau hom polyethylene nrog cov ntsiab lus sib txawv thiab qhov ntom ntom.

2. Colloid

Cov yam ntxwv ntawm cov colloid txiav txim siab tus yuam sij rau qhov zoo thiab qhov tsis zoo ntawm cov yeeb yaj kiab tiv thaiv. Cov yeeb yaj kiab tiv thaiv siv rau hauv cov nplaum nplaum nplaum muaj ob hom: hnyav-raws li polyacrylate nplaum thiab dej-soluble polyacrylate nplaum; lawv muaj cov yam ntxwv sib txawv.

Solvent-based polyacrylate nplaum nplaum

Solvent-based polyacrylate nplaum yog cov kuab tshuaj organic ua qhov nruab nrab kom yaj cov acrylic monomer; lub colloid yog pob tshab heev, qhov pib viscosity kuj tsawg, thiab tiv taus kev laus txog li 10 xyoo thaum raug ultraviolet teeb; cov colloid kuj yuav maj mam kho. Tom qab cov yeeb yaj kiab tau kho corona, polyacrylate nplaum tuaj yeem ncaj qha coated yam tsis muaj primer. Polyacrylate nplaum yog qhov nyuaj dua thiab muaj cov dej tsis zoo, yog li kev tiv thaiv zaj duab xis adhesion plays qeeb dua; Txawm tias tom qab lub siab, cov gel thiab qhov chaw yuav tsum tau tshaj tawm tseem tsis tuaj yeem tiv tauj tag nrho. Muab tso rau 30 ~ 60 hnub tom qab, nws yuav tag nrho nyob rau hauv kev sib cuag nrog rau saum npoo yuav tsum tau muab tso rau kom tiav qhov kawg adhesion, thiab qhov kawg adhesion nyhav yuav ntau dua adhesion ntawm adhesion ntawm 2 ~ 3 zaug, adhesion ntawm cov yeeb yaj kiab tiv thaiv, yog tias tsim nyog rau lub rooj tsavxwm Hoobkas txiav, tus neeg siv kawg rhuav cov zaj duab xis thaum muaj Nws yuav ua haujlwm hnyav heev lossis txawm tias tsis tuaj yeem tawg.

Dej-soluble polyacrylate nplaum nplaum

Dej-soluble polyacrylate nplaum siv dej ua ib qho nruab nrab kom yaj cov acrylic monomer. Nws kuj muaj cov yam ntxwv ntawm cov kuab tshuaj raws li polyacrylate nplaum, tab sis cov colloid yuav tsum tau zam kom txo tau kev sib cuag nrog dej vapor thiab tiv thaiv cov kua nplaum seem. Kev tsim lub teb chaws feem ntau siv cov colloid los tsim cov yeeb yaj kiab tiv thaiv vim tias cov dej-soluble polyacrylate nplaum yog ntau tus phooj ywg ib puag ncig thiab tsis xav tau cov khoom hnyav rov qab.

3. Cov yam ntxwv ntawm cov colloid

Adhesion

Hais txog ib lub sij hawm thaum cov zaj duab xis tiv thaiv los ntawm qhov chaw yog affixed rau lub zog yuav tsum tau tev. Lub zog adhesion muaj feem xyuam rau cov khoom siv, siab, lub sijhawm ntawm daim ntawv thov, lub kaum sab xis, thiab qhov kub thiab txias thaum tshem tawm cov yeeb yaj kiab. Raws li Txheej Txheej Online, feem ntau, nrog rau lub sij hawm thiab siab, lub adhesion quab yuam kuj yuav nce; kev tiv thaiv zaj duab xis adhesion tuaj yeem nce ntau dhau los kom tsis txhob muaj cov nplaum nplaum thaum tawg cov yeeb yaj kiab.Feem ntau, qhov adhesion yog ntsuas los ntawm 180-degree peeling test.

Kev sib koom tes

Hais txog lub zog ntawm lub colloid sab hauv, raws li ib tug tiv thaiv zaj duab xis ntawm lub colloid cohesion yuav tsum siab heev; txwv tsis pub, nyob rau hauv tearing lub tiv thaiv zaj duab xis, lub colloid yuav tawg nyob rau hauv, ua rau cov residual nplaum. Kev ntsuas kev sib koom ua ke: Cov yeeb yaj kiab tiv thaiv yuav raug muab khi rau ntawm cov hlau tsis huv, thiab qhov hnyav tshwj xeeb yuav raug dai rau ntawm cov yeeb yaj kiab tiv thaiv los ntsuas seb yuav siv sijhawm ntev npaum li cas los rub tawm cov yeeb yaj kiab tiv thaiv los ntawm qhov hnyav. Yog tias lub zog nplaum ntau dua li lub zog cohesive, rhuav tshem cov yeeb yaj kiab tiv thaiv, thiab cov nplaum nplaum txuas nrog ntawm daim ntawv cog lus yuav tawg, ua rau cov nplaum seem.

Adhesion

Qhov no yog hais txog lub zog sib txuas ntawm cov nplaum thiab zaj duab xis. Yog tias lub zog adhesion ntau dua li lub zog cohesion, yog tias cov yeeb yaj kiab tiv thaiv raug tshem tawm, cov ntawv cog lus ntawm cov nplaum nplaum thiab cov yeeb yaj kiab yuav tawg, ua rau cov nplaum seem.

UV Resistance

Polyacrylate nplaum yog UV resistant, pob tshab polyacrylate nplaum tiv thaiv zaj duab xis nrog UV stabilizer; nws yog UV resistant mus txog 3 ~ 6 lub hlis. Kev siv cov cuab yeej siv huab cua simulation los ntsuas UV lub zog ntawm cov yeeb yaj kiab tiv thaiv los ntawm kev kho qhov kub ntawm hluav taws xob siv hluav taws xob, thiab kev sib xyaw kom haum rau kev hloov pauv huab cua txhua 3 teev ntawm cov av noo siab thiab 7 teev ntawm ultraviolet hluav taws xob rau lub voj voog ntawm 50 xuab moos ntawm kev sim yog sib npaug rau qhov sib npaug ntawm kev tso tawm sab nraum ib hlis.
