Cyclohexilamine in rubber applications

Rubber latex is a stable dispersion of polymeric substances in aqueous medium and is essentially a two phase systems :
1. Disperse phase ( discontinous phase of rubber molecules )
2. Dispersion medium ( aqueous continous phase of serum )

Natural Rubber Latex ( NR Latex ) is the most widely used latex for the manufacture of latex based rubber products.

                                                                   Adhesives and PV Latex.

1. DIPPED LATEX PRODUCTS

    Dipping process is described as : Immersion of a former into a suitable 

    latex compound followed by a slow withdrawal in such a way so that a 

    uniform deposit of latex compound film is formed around     the outside of 

    the former which is subsequently dried, leached, vulcanized and stripped to 

    obtain a finished product.

    The dipping methods are classified as straight DIP, SINGLE DIP, MULTI DIP, WET 
    COACERVANT DIP, DRY COACERVANT DIP, HEAT SENSITIZED DIP and ELECTRO
    DEPOSITION DIP.

    DRY COACERVANT DIPPING ( Coagulant Dipping )
    The most widely used dipping method, involves use of dry coacervants such as calcium chloride,
    calcium nitrate, cyclohexyl ammonium acetate & a few other salts.

The former is then dipped into latex compound and allowed to dwell for optimum time to build up desired thickness. The dwell time depends on the type & concentration of the coacervant and the stability of latex compound towards the coacervant.

One of the example of dry coacervant solutions as belows :
Cyclohexyl ammonium acetate used as coacervant when products of optimum clarity are desired. This also provides superior bead adhesion and mild antioxdiant action.

Lateks karet adalah dispersi zat polimer yang stabil dalam media berair dan pada dasarnya merupakan sistem dua fase:

1. Fase dispersi (fase terputus dari molekul karet)

2. Media dispersi (fase serum kontinyu)

Lateks Karet Alam (NR Latex) merupakan lateks yang paling banyak digunakan untuk pembuatan produk karet berbasis lateks.

1. PRODUK LATEX DIPPED

    Proses pencelupan digambarkan sebagai: Perendaman " mould/ former " menjadi 

    cocok senyawa lateks diikuti dengan penarikan sedemikian rupa sehingga 

    lapisan seragam film senyawa lateks terbentuk di sekitar bagian luar

    mould/ former  yang kemudian dikeringkan, dicuci, divulkanisasi dan dilucuti 

    untuk mendapatkan produk jadi.

    Metode pencelupan diklasifikasikan sebagai DIP lurus, DIP TUNGGAL, DIP 

    MULTI, DIP COACERVANT BASAH, DIP COACERVANT KERING, DIP 

    SENSITIS PANAS DAN PANAS DIP DEPOSISI ELEKTRO. DIPPING 

    COACERVANT KERING (Pencelupan Koagulan) 

    Metode celup yang paling banyak digunakan,   melibatkan penggunaan 

    coacervant kering seperti kalsium klorida, kalsium nitrat, sikloheksil 

    amonium asetat & beberapa garam lainnya.

Yang pertama kemudian dicelupkan ke dalam senyawa lateks dan dibiarkan diam selama waktu yang optimal untuk membangun ketebalan yang diinginkan. Waktu tunggu tergantung pada jenis & konsentrasi coacervant dan kestabilan senyawa lateks terhadap coacervant.

Salah satu contoh larutan coacervant kering sebagai berikut:

Cyclohexyl ammonium acetate digunakan sebagai coacervant jika diinginkan produk dengan kejernihan optimal. Ini juga memberikan daya lekat yang unggul dan tindakan antioksidasi ringan.
