Lintlha:
1.Liteko tse ka holimo li sebelisitse lipoleiti tsa tšepe tse batang tse 0.8mm tse teteaneng tse nang le botenya ba li-microns tse 50-70.
2.Tlhahiso ea ts'ebetso ea ho roala ka holimo e ka fetoha ka phetoho ea 'mala le khanya.
Kakaretso ea khaso:
9-11 sq.m./kg; botenya ba filimi li-microns tse 60 (tse baloang ka sekhahla sa tšebeliso ea phofshoana ea 100%)
Ho paka le ho palama:
mabokose a kentsoe ka mekotla ea polyethylene, boima ba letlooa ke 20kg; Lisebelisoa tse se nang kotsi li ka tsamaisoa ka litsela tse sa tšoaneng, empa feela ho qoba letsatsi le tobileng, mongobo le mocheso, le ho qoba ho kopana le lik'hemik'hale.
Litlhoko tsa polokelo:
E hloekile, e omme, e nang le moea, hole le khanya, mocheso oa kamore o ka tlase ho 30 ℃, 'me e lokela ho kenngoa mohloling oa mollo, hole le mohloli oa mocheso. Nako ea polokelo e sebetsang ke likhoeli tse 12 ho tloha letsatsing la tlhahiso. Qoba ho stacking ho feta 4 layers.
Lintlha:
Li-powders tsohle li halefisa tsamaiso ea ho hema, kahoo qoba ho hema phofo le mouoane ho tloha ho folisa. Leka ho qoba ho kopana ka ho toba pakeng tsa letlalo le ho roala phofo. Hlatsoa letlalo ka metsi le sesepa ha ho hlokahala. Haeba motho a shebana le batho mahlong, hlatsoa letlalo hang-hang ka metsi a hloekileng 'me u batle ngaka hang-hang. Lera la lerole le phofshoana ea phofshoana li lokela ho qojoa holim'a metsi le hukung e shoeleng. Likaroloana tse nyane tsa organic li tla hotetsa le ho baka ho phatloha tlasa motlakase o tsitsitseng. Lisebelisoa tsohle li lokela ho etsoa fatše, 'me basebetsi ba kaho ba roale lieta tse thibelang li-static ho boloka fatše ho thibela motlakase o tsitsitseng.
