Tswv yim Qhia rau Adhesives

Phau Ntawv Qhia Txog Kev Siv Tshuaj nplaum ---- Txee Lub Neej, Lub Zog Muaj Zog, thiab Kev Tiv Thaiv Tseem Ceeb

Adhesives yog cov khoom siv tshuaj lom neeg tiag tiag uas txhua tus nquag siv hauv lub neej txhua hnub. Cov nplaum nplaum feem ntau suav nrog cov nplaum nplaum nplaum, ob sab - daim kab xev, daim kab xev nplaum, cov nplaum nplaum, thiab lwm yam. Niaj hnub no, peb yuav qhia qee cov lus qhia yooj yim rau kev siv cov nplaum no. Kuv ntseeg siab tias thaum koj nyeem cov lus no tas, koj yuav tau txais qee yam tseem ceeb.

Thaum lub sij hawm sib txuas cov txheej txheem ntawm cov kua nplaum, tus intermediary uas txuas ob cov ntaub ntawv - uas yog, cov kua nplaum nws tus kheej - feem ntau yog nyob rau hauv ib daim ntawv aqueous. Nws belongs rau qeb ntawm cov tshuaj zoo thiab tuaj nyob rau hauv ntau yam. Nws yog feem ntau cais raws li lub hauv paus nplaum (binder), daim ntawv lub cev, txoj kev kho, thiab cov khoom ntawm cov substrates yuav tsum tau sib koom ua ke. Nyob rau hauv luv luv, kev vam meej ntawm kev sib raug zoo cia siab rau 30% ntawm cov nplaum thiab 70% ntawm cov txheej txheem (cov txheej txheem).

1. Txee lub neej

1. Txhua yam khoom muaj lub sijhawm khaws cia. Raws li cov qauv thoob ntiaj teb, lub txee lub neej yog txhais nyob rau hauv chav tsev kub (24 ° C). Rau acrylic nplaum, qhov ntsuas kub yog 20 ° C.

2. Rau acrylic - raws li cov khoom, qhov kub thiab txias, lub txee lub neej luv dua.

3. Rau dej - raws li cov khoom, qhov kub thiab txias hauv qab - 1 ° C yuav cuam tshuam ncaj qha rau cov khoom zoo.

1. Lub zog

1. Tsis muaj ib yam dab tsi li cov nplaum nplaum nyob hauv lub ntiaj teb. Rau cov substrates sib txawv, nws yog qhov zoo tshaj plaws los xaiv cov nplaum tshwj xeeb tsim rau cov khoom tshwj xeeb.

2. Yog hais tias lub substrate nws tus kheej muaj tsawg inherent lub zog, tsis tas yuav tsum tau xaiv ib tug high-strength nplaum nplaum; txwv tsis pub, koj yuav dhau - qhia thiab nce nqi tsis tsim nyog.

3. Tsis txhob tsom mus rau qhov siab pib lub zog ntawm daim ntawv cog lus; durability yuav tsum tau muab rau kev txiav txim siab.

4. Adhesives kho ntawm qhov kub thiab txias feem ntau muaj kev ua tau zoo dua li cov kho ntawm chav tsev kub. Yog xav tau lub zog siab thiab ua haujlwm zoo, yuav tsum xaiv cov nplaum kub kub kub kub.

5. Rau Ethyl2-Cyanoacrylate adhesives (502 super kua nplaum), tshwj tsis yog kev kho thaum muaj xwm txheej ceev, me me - thaj chaw thaj chaw, lossis daim ntawv thov cov kab ntau lawm, lawv tsis pom zoo rau cov ntaub ntawv uas yuav tsum tau muaj zog sib txuas.

1. Lwm yam kev xav

1. Cov kua nplaum dawb (PVA nplaum) thiab urea - formaldehyde resin adhesives tsis tuaj yeem siv rau kev sib txuas hlau.

2. Rau cov ntawv thov kom pom tseeb, koj tuaj yeem xaiv polyurethane adhesives, optical epoxy adhesives, saturated polyester adhesives, los yog polyvinyl acetal adhesives.

3. Adhesive yuav tsum tsis txhob corrosive rau cov substrates tau sib koom. Piv txwv li, hnyav-raws li neoprene nplaum yuav tsum tsis txhob siv rau nthuav polystyrene ua npuas ncauj boards.

4. Adhesives nrog siab brittleness tsis haum rau kev sib txuas cov ntaub ntawv mos los yog hloov tau yooj yim.

1. Kev ceev faj rau Siv Ob-Part (AB) Adhesives

1. Rau ob - cov khoom nplaum, ib txwm ua raws li qhov sib xyaw ua ke tau teev tseg hauv phau ntawv qhia.

2. Ua ntej siv, ob yam khoom yuav tsum tau nplawm kom huv si thiab uniformly. Tsis txhob tawm ntawm qhov chaw tsis sib xyaw; txwv tsis pub, cov nplaum yuav tsis kho.

3. Cov substrates yuav tsum tau ntxuav kom huv si thiab yuav tsum tsis muaj dej noo (tshwj tsis yog cov nplaum tsim los rau kev kho hauv qab dej).

4. Txhawm rau ua kom muaj kev sib raug zoo siab, cov substrates yuav tsum tau abraded (sanded) kom ntau li ntau tau.

5. Qhov tsim ntawm qhov sib koom ua ke ncaj qha cuam tshuam rau qhov kawg ntawm daim ntawv cog lus.

6. Cov nplaum yuav tsum tau tov thiab siv tam sim ntawd. Tsis txhob cia nws sawv ntev dhau tom qab sib tov. Rau ceev ceev - kho hom, lub sijhawm ua haujlwm feem ntau yuav tsum tsis pub tshaj 2 feeb.

7. Yog tias xav tau lub zog siab dua thiab kho sai dua, cua sov tuaj yeem siv raws li qhov tsim nyog. Thaum thov cov nplaum, txheej yuav tsum tsis txhob tuab heev; hais txog 0.5 mm yog pom zoo. Cov khaubncaws sab nraud povtseg tau txo qis kev sib raug zoo.

8. Thaum lub sij hawm sib txuas, nws yog qhov zoo tshaj plaws los siv lub siab los yog ruaj ntseg nrog cov clamps.

9. Rau lub zog siab tshaj plaws, tso cai rau kev sib koom ua ke kom so tsawg kawg 24 teev tom qab sib txuas.

10. Rau ib qho - cov khoom hnyav - raws li los yog dej - raws li cov nplaum, ib txwm do kom huv si ua ntej siv.

11. Rau cov kuab tshuaj - raws li cov khoom lag luam, tom qab siv cov nplaum nplaum, tso cai rau saum npoo av rau huab cua - kom qhuav kom txog thaum nws tsis muaj tacky ua ntej koom ua ke.
