ການຮັກສານໍ້າ HPMC
ການຮັກສານໍ້າ HPMC is a non-ionic cellulose ether. In cement mortar and gypsum-based slurry, it mainly plays a role of water retention and thickening, which can effectively improve the adhesion and sag resistance of the slurry. It is an indispensable additive in mortar and paste. ການຮັກສານໍ້າ HPMC produced by Milestone Industrial Co. Ltd. has high purity and good quality. It has excellent water retention and thickening properties when used in mortar and gypsum. It is the first choice for cellulose ethers in your construction industry.

ຄວາມສາມາດໃນການຮັກສານໍ້າແລະປະລິມານການຮັກສາ HPMCwater ໄດ້ຮັບຜົນກະທົບຈາກລະດູການບໍ?
1) Since air temperature, wind pressure and other factors will affect the volatilization rate of water in cement mortar and gypsum-based products, there are some differences in the water retention effect of the same amount of ການຮັກສານໍ້າ HPMC in different seasons.
2) ໃນລະດູການທີ່ແຕກຕ່າງກັນ, ຜົນກະທົບການຮັກສາໄວ້ຂອງນ້ ຳ ສາມາດປັບໄດ້ໂດຍການເພີ່ມຫລືຫຼຸດ ຈຳ ນວນນ້ ຳ HPMC ໃນລະຫວ່າງການກໍ່ສ້າງສະເພາະ. ສົ່ງເສີມປູນແລະຫີນກາວເພື່ອສະແດງການຮັກສານ້ ຳ.

ປະສິດທິພາບໃນການ ດຳ ເນີນງານສະເພາະມີດັ່ງນີ້:
If you want to achieve the water retention effect during the high temperature summer construction, you need to add high-quality HPMC water retention in sufficient quantities according to the formula, so that the water will not lose too fast during the operation; if you do not add high-quality ການຮັກສານໍ້າ HPMC, the high temperature The operation will have quality problems such as insufficient hydration, reduced strength, cracking, hollowing and falling off caused by excessive drying, and it will also increase the difficulty of construction for workers.
If under non-summer and non-high temperature conditions, as the temperature drops, the amount of ການຮັກສານໍ້າ HPMC can be gradually reduced, so that the same water retention effect can be achieved.
