Inoshanda Gaidhi kune Adhesives

Practical Guide kune Adhesives----Sherufu Hupenyu, Bond Simba, uye Key Precautions

Adhesives imhando yechigadzirwa chemakemikari chinowanzo shandiswa nemunhu wese muhupenyu hwezuva nezuva. Zvinonamira zvakajairika zvinosanganisira super glue, kaviri - mativi tepi, adhesive tepi, glue tsvimbo, nezvimwe. Nhasi, tichagovera mamwe matipi anobatsira ekushandisa izvi zvinonamira. Ndine chivimbo chokuti paunozopedza kuverenga nyaya ino, unenge wawana chimwe chinhu chinokosha.

Panguva yekubatana kweglue, murevereri anobatanidza zvinhu zviviri - kureva, glue pachayo - kazhinji mune fomu ine mvura. Iyo ndeye chikamu chemakemikari akanaka uye inouya mumhando dzakasiyana-siyana. Iyo inonyanya kurongerwa zvichienderana neadhesive base (binder), chimiro chemuviri, nzira yekurapa, uye zvinhu zvema substrates anofanirwa kusungirirwa. Muchidimbu, kubudirira kwekubatana kunotsamira 30% pane adhesive uye 70% pamaitiro (technique).

1. Chigadzirwa chese chine hupenyu hwakasarudzika. Zvinoenderana nezviyero zvepasirese, hupenyu hwesherufu hunotsanangurwa pasi pemamiriro ekushisa kwekamuri (24 ° C). Pakunamira kwe acrylic, tembiricha yereferensi i20°C.

2. Kune acrylic-zvakavakirwa zvigadzirwa, iyo yakanyanya tembiricha, iyo ipfupi hupenyu hwesherufu.

3. Zvemvura - zvigadzirwa, tembiricha iri pazasi -1°C inozokanganisa kunaka kwechigadzirwa.

1. Simba

1. Iko hakuna chinhu chakadai sekunamira kwepasi rose munyika. Kune akasiyana ma substrates, zviri nani kusarudza yakasarudzika adhesive yakagadzirirwa iyo chaiyo zvinhu.

2. Kana iyo substrate pachayo ine yakaderera inherent simba, hapana chikonzero chekusarudza yakakwirira-simba rinonamatira; kana zvisina kudaro, iwe ungadai uri pamusoro-kutsanangura uye kuwedzera mari zvisina basa.

3. Usatarise chete pane yakakwirira yekutanga chisungo simba; kusimba kunofanirawo kupiwa fungidziro yakafanira.

4. Zvinamira zvinorapa pakupisa kwepamusoro zvinowanzopa kuita zvirinani pane izvo zvinorapwa patembiricha yepakamuri. Kana kusimba kwepamusoro uye kusimba kwakanaka kuchidikanwa, yakakwirira - tembiricha yekurapa inonamira inofanira kusarudzwa.

5. YeEthyl2-Cyanoacrylate adhesives (502 super glue), kunze kwekugadziriswa kwechimbichimbi, diki-nzvimbo yekumisikidza, kana kuenderera mberi kwekugadzira mitsara maapplication, haakurudzirwe kune zvinhu zvinoda simba rekubatana.

1. Zvimwe Zvinofungwa

1. Namatidza jena (PVA adhesive) uye urea-formaldehyde resin adhesives haigone kushandiswa pakusunga simbi.

2. Pazvishandiso zvinoda kujeka, unogona kusarudza zvinonamira zvepolyurethane, zvinonamira epoxy epoxy, zvinonamira zvepolyester zvakazara, kana zvinonamira zvepolyvinyl acetal.

3. Iyo yekunamatira haifanirwe kuve yakaora kune iyo substrates iri kusungwa. Semuenzaniso, solvent-based neoprene adhesives haifanirwe kushandiswa pakuwedzera polystyrene foam board.

4. Adhesives ane high brittleness haana kukodzera kubatanidza zvinyoro kana flexible zvinhu.

1. Chengetedzo Yekushandisa Maviri - Chikamu (AB) Adhesives

1. Kune maviri - zvinonamirwa zvechikamu, gara uchitevera chiyero chekusanganisa chinotsanangurwa mubhuku rekuraira.

2. Usati washandisa, zvikamu zviviri zvinofanira kukurudzirwa zvakakwana uye zvakafanana. Usasiya chero nzvimbo dzisina kusanganiswa; kana zvisina kudaro, chinonamira hachizorapi.

3. Iyo substrates inofanira kucheneswa zvakakwana uye inofanira kunge isina unyoro (kunze kwekunge iyo yakanamatira yakagadzirirwa kurapa pasi pemvura).

4. Kuti uwane simba rekubatana kwepamusoro, ma substrates anofanirwa kuvharwa (sanded) zvakanyanya sezvinobvira.

5. Kugadzirwa kwekubatana kwakabatanidzwa kunobata zvakananga kusimba kwekupedzisira kwechisungo.

6. Iyo yekunamatira inofanira kusanganiswa uye kushandiswa pakarepo. Usaisiye yakamira kwenguva yakareba mushure mekusanganisa. Nekukurumidza - kurapa mhando, nguva yekushanda haifanirwe kudarika maminetsi maviri.

7. Kana simba repamusoro uye nekukurumidza kurapwa kuchidikanwa, kupisa kunogona kuiswa sezvakakodzera. Paunenge uchiisa kunamatira, jira harifaniri kunge rakanyanyisa; inenge 0.5 mm inokurudzirwa. Makobvu akaturikidzana anonyatso kuderedza kushanda kwekubatana.

8. Munguva yekubatana, zviri nani kushandisa kumanikidza kana kuchengetedza zvikamu ne clamps.

9. Kuti uwane simba guru, bvumira gungano rakasungwa kuti rizorore kweinenge maawa makumi maviri nemana mushure mekubatana.

10. Kune imwe - chinhu chinonyungudutsa - chakavakirwa kana mvura

11. For solvent-based products, mushure mekuisa chinonamira, tendera iyo yakavharwa pamusoro kuti iende kumhepo - yakaoma kusvika isingachaite tacky isati yabatanidza zvikamu pamwechete.
