Abstract
An automatic technology for manufacturing thin-wall cement pipe includes preparing cement mortar from water, cement and fine and through proportionally stirring for 2-5 min, coating demoulding agent on the inner surface of mould, arranging reinforcing fibre material, closing mould, rotating at 100-700 rpm for 20-120 secons while pouring mortar for 10-60 seconds, demoulding, and curing. Its advantages are high productivity, quality and surface density, and uniform thickness of wall.
Description
Technical field
The invention relates to the production method of thin wall cement pipe automatic moulding, particularly a kind of manufacture method of using shaping equipment to produce thin wall cement pipe.
Background technology
At present, produce thin wall cement pipe, the manual operations of general employing manpower, its method is: the mortar that mixes cement, manual cement mortar (and adding grid cloth), the health finished product of shakeouing on the sheet metal mould, its shortcoming is that labour intensity is big, production efficiency is low, the thickness of pipe wall inequality, and the low and occupied ground of intensity is big etc.
Summary of the invention
The objective of the invention is to overcome the problem that prior art exists, providing a kind of is suitable for using shaping equipment to produce the manufacture method of thin wall cement pipe, utilize production method of the present invention, can significantly improve product quality; the thin wall cement pipe surface density is big; wall thickness is even, reduce labour intensity, enhance productivity.
The present invention includes the following step: (1) mortar that mixes cement, cement mortar ratio: water 0.2-0.5, cement 1-2, fine sand 2-3, add in the mixer simultaneously, mixing time 2-5 minute, cement mortar optimal proportion: water 0.2-0.4, cement 1-1.5, fine sand 2-2.5, best mixing time is 3-4 minute, (2) installation forming mould, at mould inner surface coating release agent, place reinforcing fiber materials, add prefabricated cement end socket and matched moulds, in the rotating cylinder of the automatic moulding centrifugal device of packing into, and be fixed, (3) automatic moulding thin wall cement pipe starts rotating cylinder and rotates from low speed to high speed, stops to low speed again, take out the forming thin wall cement pipe mould, maximum speed 100-700 rev/min, optimum speed 150-500 rev/min, maximum speed time 20-120 second, maximum number of revolutions time 30-100 is best second, raising speed time 5-20 second, best raising speed time 10-15 second, deceleration time 5-20 second, best deceleration time 10-15 second, mobile material feeding time 10-60 second.(4) health finished product, building the forming thin wall cement pipe mould with Polypropylence Sheet keeps flat, health 4-5 hour, temperature 15-30 degree centigrade, form removal is taken out forming thin-walled pipe of cement and is kept flat then, waters health 10-24 hour, can stack at last to keep flat, per 5 hours of daytime watered 1 time, and health finished forming process in 48 hours.
The specific embodiment
A kind of manufacture method of thin wall cement pipe automatic moulding, comprise the following steps: (1) mortar that mixes cement, cement mortar in proportion: water 0.2-0.4, cement 1-1.5, fine sand 2-2.5, add in the mixer simultaneously, mixing time 2-4 minute, (2) installation forming mould, at mould inner surface coating release agent, place reinforcing fiber materials, add prefabricated cement end socket and matched moulds, be fixedly connected into cylinder integral body with returning the type locking pin, pack into then in the rotating cylinder of automatic moulding centrifugal device, and be fixed, (3) automatic moulding thin wall cement pipe starts rotating cylinder and rotates from low speed to high speed, stops to low speed again, take out the forming thin wall cement pipe mould, maximum speed 150-500 rev/min, maximum number of revolutions time 30-100 second, raising speed time 10-15 second, deceleration time 10-15 second, mobile material feeding time 10-60 second, (4) health finished product is built the forming thin wall cement pipe mould with Polypropylence Sheet and is kept flat, health 4-5 hour, temperature 15-30 degree centigrade, form removal is taken out forming thin-walled pipe of cement and is kept flat then, waters health 10-24 hour, can stack at last and keep flat, stack and highly be no more than 2 meters, per 5 hours of daytime watered 1 time, and health finished forming process in 48 hours.
Embodiment
(1) mortar that mixes cement, cement mortar in proportion: water 0.3, cement 1.5, fine sand 2.5, add in the mixer simultaneously, mixing time 4 minutes, (2) installation forming mould, at mould inner surface coating release agent (machine oil), place reinforcing fiber materials (glass fiber grid cloth), add prefabricated cement end socket and matched moulds, be fixedly connected into cylinder integral body with locking pin, pack into then in the rotating cylinder of automatic moulding centrifugal device, and be fixed, (3) automatic moulding thin wall cement pipe, starting rotating cylinder rotates from low speed to high speed, stop to low speed again, 500 rev/mins of maximum speeds, 60 seconds maximum speed time, 15 seconds raising speed time, deceleration time 15 seconds, 40 seconds mobile material feeding time, take out the forming thin wall cement pipe mould, (4) health finished product, building the forming thin wall cement pipe mould with Polypropylence Sheet keeps flat, health 5 hours, temperature 20-28 degree centigrade, form removal is taken out forming thin-walled pipe of cement and is kept flat then, the health 20 hours of watering, can stack at last and keep flat, per 5 hours of daytime watered 1 time, and health finished forming process in 48 hours.By above-mentioned process, the thin wall cement pipe face of 80 millimeters of the calibers of manufacturing, 60 millimeters of wall thickness is smooth, and density is big, and wall thickness is even, and quality is good, the production efficiency height, and save raw material.
