CAS 52-51-7

Rubber Chemical PVI ,also called PVI or CTP also known as N-(Cyclohexylthio) phthalimide used as ant scorching agent, is an flame retardant for NR and synthetic diene rubbers. PVI is a pre-vulcanization inhibitor which enables processing safety to be controlled in a predictable manner in sulphur curable compounds.
Applicationï¼?
It is a high effective pre-vulcanization inhibitor. It's applied in NR,SBR,BR,IIR,CR,EPM,EPDM, NBR with cure system consisting of sulfur and Thiazole but mainly Sulphenamide Accelerator. Suitable for the all kinds of tire, Rubber hose, belts and other rubber products.

Used for diazo paper making

Slurry pump refers to speak refers to through the use of centrifugal force (pump impeller rotation) role of solid, liquid mixed media energy increase of a mechanical, electrical energy into the medium of kinetic energy and potential energy of the equipment. Mainly used in: mining, power plants, dredging, metallurgy, chemical industry, building materials and petroleum and other industry sectors.

Slurry pump conveys a mixture of solid particles containing dross and water. But from the principle of slurry pump belongs to a centrifugal pump, in the iron and steel enterprises are mainly used for converter dust water, blast furnace gas scrubbing water, continuous casting turbid ring water and rolling steel turbid ring water and other systems of slurry transport.

Pipeline centrifugal pumps are general-purpose equipment for conveying clear water and liquids with similar physical and chemical properties, widely used in industrial and urban water supply and drainage, high-rise building pressure boosting, fire-fighting systems, HVAC circulation and other fields [2]. According to the installation form can be divided into vertical and horizontal, according to the impeller structure is divided into closed, open and semi-open [1], the adaptable medium temperature range -20 â?? to 240 â?? [3], typical models include ISG, ISW, IRG, etc. [2] [4].
The equipment consists of impeller, pump body, sealing ring and other core components, the impeller rotates to generate centrifugal force to achieve liquid transport, the pump body plays a supporting role, and the sealing system to protect the operating vacuum. It adopts modular piping design, equipped with high-efficiency hydraulic model, supports electric drive and direct connection structure, featuring low noise, small footprint and easy maintenance. Installation requires precise calculation of suction height and ensuring pipeline sealing, and the performance curve reflects the relationship between flow rate, head and power [4]. Common faults such as air binding can be solved by filling water and exhausting air, and the bearings and sealing parts need to be overhauled regularly [2].
