FEATURES

It is a clay mineral being up to standards of API 13 A ( Nontreated bentonite )

It has Sodium based content and contains at least 90 % montmorillonite. It is completely natural ,contains not even one type additive. It has high swelling capacity ( 15-20 times by volume)

It is in conformity with TS EN 13500 Nontreated Bentonite Specifications.

It easily disperses and doesn’t become lumpy when it is added to water.

APPLICATIONS

Drilling Mud

  • Due to its high viscosity and gel forming property , it ensures aggravating materials in drilling mud to stay in the suspension.
  • It helps to obtain an effective well cleaning by reducing the slip speed of cuttings in the mud.
  • Due to its high plastering property it ensures well stability by forming uniform and steady filter cake on the wellbore wall.
  • Through its high lubricity, it performs good lubricating on wellbores, drill bits and drill strings.

Civil Engineering

  • It ensures cementing process to be permanent and steady in diaphragm wall constructions, in injection operations, in settings of regulator covers and tunnel workings. During cementation process it is allowed to add only sodium montmorillonit Non-treated bentonite to cement. Treated bentonite definitely can’t be used for this purpose because it hardly penetrates to ground due to viscosity increases.
  • It ensures low-cost impermeability in injection operations and in concrete shear walls of civil engineering , by slurry trench applications.
  • Highly viscous slurry can be prepared with a small amount of the natural bentonite, KAR-BEN.
  • KAR-BEN has an extremely high swelling capacity. Its aqueous suspensions have such a high viscosity that, to the value of 40 marsh /sec which normally used for diaphragm walls and similar applications is reached after a swelling time of maximum 2 hours with 45-50 kg/m3 KAR-BEN natural bentonite suspensions.

Construction

  • It is used in construction of cut-off walls and impermeable walls.
  • It is used in impermeable building walls.
  • It is used in load-bearing building walls.

Packing

  • 50 kg multilayer paper bags , loose and palletised.
  • 1000 kg-1200 kg bigbags.
  • By Silo Trailer.

GENERAL INFO

  • While preparing cement suspensions, natural bentonite KAR-BEN must be mixed to water first and at least after two hours cement should be added.
  • It is recommended to add 0,3% – 0,7% (Of solid material added) Sodium phosphate or 5 % sodium silicate to the cement suspensions, considering the application aim, depending the heat of the used water.
  • It is more effective and economic to get enough natural bentonite KAR-BEN suspension ready at the beginning of the work.

T.T. K. 461. Maddesine Göre Rüçhan Hakkını Kullanmaya Davet İlanı:

Şirket ortaklarının 6102 sayılı Türk Ticaret Kanununun 461. Maddesi hükümlerine göre rüçhan hakkını kullanmaları, rüçhan haklarını kullanmak istemeyenlerin devir ya da feragat ettiklerine ilişkin beyanlarını bildirmeleri, sermaye artışında bulunmak isteyen ortakların kanun ve ana sözleşme gereği taahhüt etmeleri gereken tutara ilişkin ödemelerini (en az ¼ oranında) Türkiye Halk Bankası Necatibey Şubesi TR67 0001 2009 3860 0010 2614 14 iban nolu hesaba sermaye artırım bedeli olarak bloke ettirmeleri ve bloke yazısı ile ödeme dekontlarının şirketimize ibraz etmeleri için iş bu kararın ilan tarihinden itibaren 15 günlük süre tanınmıştır.

15 günlük süre içerisinde rüçhan hakkı ile ilgili beyanda bulunmayan ya da sermaye artışına katılacakların sermaye koyma borcu süresi içerisinde yerine getirmemeleri halinde ihtara gerek olmaksızın haklarından vazgeçmiş sayılacaklarına, arttırılmasına karar verilen sermaye miktarının yönetim kurulu tarafından diğer bir ortağa veya ortak olmayan üçüncü şahıslara kullandırılmasına,

İşbu kararın Türk Ticaret Kanunun ilgili hükümleri gereğince tescil ve ilanına karar verilmiştir.
