HEMC Hydroxyethyl Methyl Cellulose
Nānā huahana
?O ka Hydroxyethyl Methyl Cellulose (hydroxyethyl methyl cellulose) he mea ho?ololi kemika i ho?ololi ?ia e like me ka pauka ke?oke?o a ke?oke?o paha.
?ano huahana
1. Hiki ke ho?ohehe?e ?ia ka wai maika?i: hiki ke ho?ohehe?e koke ?ia i loko o ka wai e hana i kahi ?ano like a pa?a.
2. He mea kupaianaha ka hopena mānoanoa: hiki iā ia ke ho?onui i ka viscosity o ka hopena a ho?omaika?i i kona mau waiwai rheological.
3. Hiki ke ho?opa?a wai ikaika: kōkua i ka mālama ?ana i ka wai i loko o ka ?ōnaehana a ho?emi i ka nalowale o ka wai.
4. ?O ka waika maika?i a me ke kūpa?a alkali: mālama i ka hana pa?a ma kahi ākea pH ākea.
5. Ho?opili ākea: He kūpono ia me nā ?ano mea ho?ohui a me nā mea ?ē a?e.
ho?ohana huahana
1. Ke kahua kūkulu: Ma ka putty, mortar a me nā huahana ?ē a?e, ma ke ?ano he mea mānoanoa, ka mea mālama wai a me ka mea ho?opili, ho?omaika?i i ka hana hana a me ka maika?i o ka huahana.
2. No ka la?ana, i ke kāpili tile, hiki ke ho?onui i ka ikaika ho?opa?a e pale ai i ka hā?ule ?ana o ka tile.
3. ?Oihana pena: E ho?omaika?i i ka rheology a me ke kūpa?a o ka pena, e pale i ka ua pua?a.
4. E like me ka pena wai, ua ma?alahi ka pena, a ua like ka pena.
5. Nā huahana kemika o kēlā me kēia lā: ho?ohana ?ia no ka shampoo, holoi kino, a me nā mea ?ē a?e, e ho?onui i ka pa?a a me ka pa?a o ka huahana.
6. Ho?ohana aila: ma ke ?ano he mea ho?ohui i ka wai wili e ho?omaika?i i ka hana o ka wai wili.
Ka?ina hana hana
Hana ?ia ia mai ka cellulose e ka etherification me ka ethylene oxide a me ka chloromethane.
Nā mana?o mākeke
Me ka pi?i nui ?ana o ka noi no nā mea ho?ohui ki?eki?e i nā ?oihana like ?ole, ?o Hydroxyethyl Methyl Cellulose kahi ākea ākea ākea. ?Oi aku ka nui o ka ulu ?ōma?oma?o o ke kūkulu ?ana a me ka ?oihana uhi, ?o kona pale ?ana i ke kaiapuni a me nā hi?ohi?ona hana ki?eki?e e ho?onui ai i ka hiki ke ho?omohala.
e ho?ohana i ka mālama ?ana
1. Pono e mālama ?ia ka mālama ?ana i kahi malo?o a ho?ohehe?e ?ia e pale aku i ka makū a me ka wela ki?eki?e.
2. Ke ho?ohehe?e?ia, pono e ho?ohui mālie a ho?oulu?ia e hō?oia i ka ho?opau piha?ana a pale i ka agglomeration.
3. I ka ho?ohana ?ana, pono e mālama pono ?ia ka nui o ka ho?ohui e like me nā koi kiko?ī a me nā koi.
I ka pōkole, ?o Hydroxyethyl Methyl Cellulose, me kāna mau waiwai maika?i loa a me ka nui o ka ho?ohana ?ana, he hana ko?iko?i ma nā kahua he nui, e hā?awi ana i ke kāko?o ikaika no ka ho?omaika?i ?ana i ka maika?i a me ka ho?okō ?ana i nā huahana pili.
