Te pūhui hauwaioraitiri

Ko te Hydroxyethyl cellulose (HEC) he mā, he kōwhai mārama rānei, kāore he kakara, he totoka muka, he paura rānei, kāore he paitini, i hangaia mā te whakaetere i te cellulose kawakore me te ethylene oxide (chlorohydrin rānei). He cellulose ether wairewa kore-ionic. Nā te mea he pai ngā āhuatanga o te HEC ki te whakamātotoru, te whakatārewa, te horapa, te whakaemulsifying, te here, te hanga kiriata, te tiaki i te makuku me te whakarato i ngā colloid tiaki, kua whānuitia te whakamahinga i roto i te tūhuratanga hinu, te paninga, te hanga whare, te rongoā me te kai, te kakahu, te hanga pepa me ngā polymer. Polymerization me ētahi atu mara. Kāore te Hydroxyethyl cellulose i te pumau i te pāmahana me te pēhanga noa, ka karo i te makuku, te wera, me te pāmahana teitei, ā, he tino pai te wairewa tote mō ngā dielectrics. Ka whakaaetia tōna otinga wai kia mau ki ngā kukū tote teitei, ā, he pumau.

Ngā Tohutohu
Whakauru tika atu ki te mahi whakaputa

1. Tāpirihia he wai mā ki roto i tētahi pākete nui kei roto he mīhini whakaranu kutikuti-teitei.

2. Tīmatahia te whakaoho tonu i te tere puhoi, ka tātari mārire i te hydroxyethyl cellulose ki roto i te wairewa kia ōrite.

3. Me whakaoho tonu kia mākū katoa ngā matūriki.

4. Kātahi ka tāpirihia ngā rongoā harore, ngā tāpiringa kawakore pērā i ngā tae, ngā āwhina whakamarara, me te wai haukini.

5. Whakaohokia kia memeha rawa te hydroxyethyl cellulose (ka tino piki ake te matotoru o te wairewa) i mua i te tāpiri i ētahi atu wāhanga ki te tauira, ka huri kia oti ra ano te hanga.

Kua rite ki te waipiro whaea

Ko tēnei tikanga he whakarite i te wai whaea he nui ake te kukū, kātahi ka tāpirihia ki te peita rapa. Ko te painga o tēnei tikanga he ngāwari ake, ā, ka taea te tāpiri tika ki te peita kua oti, engari me penapena tika. He rite ngā mahi ki ngā mahi 1-4 i te tikanga 1, engari kāore e hiahiatia he whakaoho nui kia memeha katoa ki roto i te wai mātotoru.

Kia tūpato
I te mea he paura, he totoka rānei te hydroxyethyl cellulose i maimoatia ki te mata, he ngāwari ki te whakahaere me te rewa ki te wai, mena ka mōhiotia ngā mea e whai ake nei.

1. I mua atu, ā, i muri i te tāpiri i te hydroxyethyl cellulose, me whakaoho tonu kia mārama rawa te wairewa.

2. Me āta tātari ki roto i te oko whakaranu. Kaua e tāpiri tika te hydroxyethyl cellulose kua hangaia hei puranga, hei pōro rānei ki roto i te oko whakaranu i roto i te nui, i te tika rānei.

3. He hononga nui tō te pāmahana wai me te uara pH o te wai ki te memeha o te hydroxyethyl cellulose, nō reira me aro nui ki tēnei.

4. Kaua rawa e tāpirihia he matū kawakore ki te ranunga i mua i te whakamahanatanga o te paura hydroxyethyl cellulose ki te wai. He mea āwhina te whakanui ake i te uara PH i muri i te whakamahanatanga mō te whakarewatanga.

5. Tāpirihia he rongoā patu harore ki te wāhi e taea ai i te wā e taea ai.

6. Ina whakamahia te hydroxyethyl cellulose matotoru-teitei, kaua te kukū o te wai whaea e neke ake i te 2.5-3%, ki te kore ka uaua te whakahaere i te wai whaea. Ko te hydroxyethyl cellulose kua tukatukahia i muri i te maimoatanga he uaua ki te hanga i ngā puranga, i ngā porowhita rānei, ā, e kore e hanga i ngā porowhita kore-rewa i muri i te tāpiri wai.
