Name: Water Wax Tree Category: Shrubs
Alias: Water wax family name: Oleaceae
Latin name: Ligustrum obtusifolium sieb. Et Zucc.
Hi light, slightly shade-tolerant, more resistant to cold. The soil is not strict, but the fertile wet soil. Fast growth, strong sprouting, resistant to pruning. Easy to transplant. Pests are few and easy to manage.
Deciduous or semi-evergreen shrubs, up to 3m in height, round crown. Dark bark. Branchy, arched, young branches pubescent. Paper leaves opposite, elliptic or oblong-obovate, 2-7 cm long, apex obtuse, sometimes pointed or dimpled, pubescent above or glabrous, inferiorly pilose along midvein; petiole length 1â€“ 4mm, densely pubescent. Panicles terminal, slightly drooping, 2â€“3.5 cm long; pedicels and bracts pubescent; flowers white, aromatic, corolla 4â€“10 mm long, tube 2 times longer than lobes. Drupe ellipsoid, black, slightly waxy white powder.
Can be used for landscape forests, parks, courtyards, grasslands and streets. Can be planted, planted or hedged.
Distribution of origin
Native to China. Shandong, Henan, Hebei, Jiangsu, Anhui, Jiangxi, Hunan, Shaanxi, Liaoning and other provinces have cultivated.
Oxygen Cylinder Filling System
With PSA principles, ETR Oxygen Cylinder Filling system can produce 93%Â±3% purity oxygen gas from compressed air directly. ETR oxygen cylinder filling system is consisted of Atlas screw air compressor, refrigerated air dryer, compressed air filter, air buffer tank, ETR Oxygen Plant, oxygen buffer tank, oxygen booster, cylinder filling station and HMI control cabinet.
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%Â±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure. With an oxygen booster, the oxygen pressure can be to 150bar and fill in cylinders.
