METHOD FOR PREVENTING SCALE FROM BEING STUCK ONTO TOILET WITH TRAP ATTACHED/DETACHED

摘要

PROBLEM TO BE SOLVED: To provide a simple and efficient method for surely preventing scales over a long period of time from being stuck onto a toilet with an attachable/ detachable trap (a men's urinal which has the built-in trap but rot-in its drainpipe). SOLUTION: Scales are prevented from being stuck to a trap holding water part of the toilet 9 with the trap attached/detached and the inside of the toilet drainpipe by hanging a solid type scale deposit preventing agent 6 which is housed in a bag body made of a water-permeable base stock such as a spunbonded nonwoven fabric and contains a solid acid as an effective component on the attaching/detaching trap 8 and keeping the pH of trap holding water of the toilet 9 in 3.5-4.5.
