Abstract
The invention discloses a production technology of a reinforced composite bathtub. The production technology of the reinforced composite bathtub comprises the following steps of preparing a mould, spraying gel coat and internal mold resin, conducting hand layup and potting, conducting trimming and dressing and performing grinding and polishing. By the adoption of the production technology, a traditional acrylic bathtub is changed, and a novel reinforced composite is adopted. Acrylic has a certain fragility and poor heat preservation performance and is prone to damage during transportation, but the adopted composite has good physical properties and good heat preservation performance.
Description
Technical field
The present invention relates to the production technology of a kind of sanitaryware, particularly relate to the production technology of a kind of reinforced composite bathtub.
Background technology
Progress along with the epoch, the change of bathing mode, the making material of bathtub also occurs to change without a stop, from wooden bathtub to iron and steel bathtub, from iron and steel bathtub to ceramic bathtub, from ceramic bathtub to acrylic bathtub, from common bathtub to high-end highest-ranking imperial concubine's independence bathtub, the production technology of product also changes therewith. The production technology of acrylic bathtub is all: acrylic cylinder body part and outer cover part synthesize after resin and fiber coating again, need to add packing material in middle gap layer during synthesis, inserts is made into by materials such as resin, calcium carbonate, pigment paste, firming agent, and after being combined finally by tooling device compacting, cutting has arranged the production of independent acrylic bathtub. Acrylic bathtub uses resin, calcium carbonate as implant, and its whole production technology is more complicated, and production environment is poor, and product is heavier, and labor intensity is big, and the material of acrylic is lighter, crisp, it is easy to damage.
