Pehea e hoʻohana aiHEC？
hoʻohui pololei i ka manawa hana
1. E hoʻohui i ka wai maʻemaʻe i loko o kahi bākeke nui i hoʻolako ʻia me kahi hui ʻoki kiʻekiʻe.
2. E hoʻomaka e hoʻoulu mau me ka māmā haʻahaʻa a kānana mālie i ka hydroxyethyl cellulose i loko o ka hopena.
3. E hoʻomau i ka hoʻoulu ʻana a hiki i ka pau ʻana o nā ʻāpana āpau.
4. A laila e hoʻohui i ka antifungal agent, alkaline additives e like me ka puaʻa, nā mea hoʻopuehu, ka wai amonia.
5. E hoʻoulu a hiki i ka pau ʻana o ka hydroxyethyl cellulose (e piʻi nui ka viscosity o ka hopena) ma mua o ka hoʻohui ʻana i nā mea ʻē aʻe i loko o ke ʻano, a wili a hiki i ka huahana i pau.
