Nā noi
1. Ma keʻano he waena, Trifluoromethanesulfonic anhydride i hoʻohana nuiʻia i kaʻoihana lāʻau lapaʻau, protein, sugar, vitamins, etc., Friedel-Crafts catalysts no ka benzylation a me ka cyclohexylation reactions.
2. Hoʻohana ʻia ka ʻoihana plastics no ka hoʻoulu ʻana i ka hopena synthesis kemika ma ke ʻano he catalyst no ka oligomerization a me ka hoʻololi ʻana o ka pahu silika Chemicalbook rubber.
3. ʻOihana kemika uila no ka hana ʻana i nā polymers conductive uila
4. ʻOihana wahie ma ke ʻano he mea hoʻoikaika no ka hopena protonation.
5. ʻO ka herbicide synthetic a me ka mea hoʻoponopono ulu no ka ʻoihana agrochemical.
6. No ka oihana ko.
7. Hoʻohana ʻia nā haʻawina Laboratory no nā hopena kikoʻī
ʻO ka lawelawe hiki iā mākou ke hāʻawi
1) Hiki ke hoʻopaʻa inoa ʻia ka ʻaelike maʻamau
2) Hiki ke pūlima ʻia ka ʻaelike hūnā
3) ʻEhiku lā hoʻihoʻi hōʻoia
ʻOi aku ka mea nui: hiki iā mākou ke hāʻawi i ka huahana wale nō, akā ʻo ka lawelawe ʻenehana hoʻonā!
He mea hana mākou, aia kā mākou hale hana ma Shandong, akā hiki iā mākou ke hāʻawi i kahi lawelawe kūʻai kūʻai hoʻokahi no ʻoe!

≤25kg: i loko o ʻekolu mau lā hana ma hope o ka loaʻa ʻana o ka uku. ＞25kg: hoʻokahi pule
Loaʻa, hiki iā mākou ke hāʻawi i nā laʻana liʻiliʻi liʻiliʻi no ke kumu loiloi maikaʻi!
1kg no ka ʻeke fpr samples, 25kg a i ʻole 50kg no ka pahu, a i ʻole e like me kou makemake.
E mālama i ka pahu i paʻa paʻa i kahi maloʻo, anuanu a maikaʻi hoʻi.
