Te etila o te pūtau (EC)He etera cellulose kore-ionic i ahu mai i te cellulose tūturu mā te tauhohenga ethylation. Nā ōna āhuatanga hanga kiriata pai rawa atu, te pumau wera, me te koretake o te matū, he whānuitia te whakamahinga i roto i ngā paninga, waituhi, rongoā, rauemi hiko, me ētahi atu ahumahi. Heoi, ko te ethyl cellulose tuku iho i rewa ki roto i ngā whakarewa waro he take pēnei i te mura, ngā āwangawanga taiao, me ngā utu whakahaere teitei. Hei whakatika i ēnei take, i whakawhanakehia ngā dispersions ethyl cellulose wai (AECD).
1. Te Whakamāramatanga me ngā Āhuatanga o ngā Mararatanga Wai Ethyl Cellulose
Ko ngā marara wai ethyl cellulose he rauemi e hanga ana i tētahi marara pumau i roto i te wai mā te whakamahi i ngā tikanga emulsification, dispersion, whakarerekētanga rānei. Ko ō rātou āhuatanga matua ko:
He mea hanga ki te wai, he mea hanga ki te taiao: Kāore e whakamahia ngā whakarewa rauropi tuku iho, e tutuki ai ngā whakaritenga o ngā paninga hou e hangai ana ki te taiao me ngā ahumahi matū matomato.
Te pumau teitei: Ko ngā matūriki etiloselulosa i roto i te marara ka marara ōrite i roto i te wāhanga wai, e whakaatu ana i te pumau rokiroki tino pai me te ātete ki te whakatō, ki te kohikohi rānei.
Te Matatini Ka Taea te Whakahaere: Mā te whakarerekē i te nui o te whakakapinga, te taumaha ngota ngota, me te hanganga whakamarara o te ethyl cellulose, ka taea te whiwhi i ngā whakamarara wai me ngā matatini rerekē hei whakatutuki i ngā whakaritenga tukanga rerekē.
Ngā Āhuatanga Hanga Kiriata Pai Rawa: Whai muri i te mimiti wai i te wā whakamaroke, ka hangaia e te ethyl cellulose he kiriata ōrite, tonu, he kaha ā-pūkaha me te pumau matū pai rawa atu.
Hototahi Kaha: Ka taea te whakaranu ki ngā momo tāpiringa, kapia, tae, me ngā whakakī, kia pai ai te whakamahi i roto i ngā peita, waituhi, me ngā paninga mahi.
2. Ngā Tikanga Whakarite
2.1. Tikanga Marara Whakapūngao
Ka whakarewahia te ethyl cellulose ki roto i tētahi whakarewa waro, kātahi ka hangaia he emulsifier me te whakaoho tere, ka hangaia he emulsion dispersion ki roto i te wai. Kātahi ka tangohia te whakarewa waro kia puta he ethyl cellulose dispersion wai. Mā tēnei tikanga ka puta he dispersion he iti te rahi o te matūriki, ā, he tino pumau.
2.2. Tikanga Marara Ā-Mīhini
Ka horahia tika te paura ethyl cellulose i roto i te āhua wai mā te kutikuti tere, mā te huri rānei. Kātahi ka tāpirihia he mea whakamarara, he mea whakamātotoru rānei hei whakau i te pūnaha. He pai tēnei tikanga mō te whakarite i ngā whakamarara wai iti te matotoru.
2.3. Tikanga Whakarerekētanga Matū
Ka whakarerekētia te ethyl cellulose mā te carboxylation wāhanga, te hydroxylation rānei, kia puta ai he rōpū hydrophilic ki tōna mata, kia taea ai e ia te hanga i tētahi marara pumau i roto i te wai. He maha ngā wā ka whakamahia tēnei tikanga i roto i ngā paninga mahi, i ngā hanganga rongoā rānei.
3. Ngā Whakamahinga o ngā Mararatanga Wai Ethyl Cellulose
3.1. Ngā Paninga Wai-Tuhinga
Hei whakamātotoru, hei āwhina hanga kiriata, hei here rānei, ka taea e ngā marara wai o te ethyl cellulose te whakapai ake i te maeneene o te paninga, te piri, me te ātete ki te pakū, me te whakaiti anō hoki i te whakamahinga o ngā whakarewa waro me te whakarei ake i te mahi taiao.
3.2. Waituhi Wai-Tuhinga
I roto i ngā waituhi tā, ka taea e ngā whakamararatanga wai ethyl cellulose te whakapai ake i te whakataurite me te ōritetanga o te tae, me te whakapai ake hoki i te tere maroke me te ātete ki te wai. He pai ēnei mō te tānga takai, te tānga flexographic, me ētahi atu whakamahinga.
3.3. Ngā Rongoā me ngā Kai
Hei kiriuhi tukunga-whakahaere-rongoā, hei paninga kai rānei, ka karohia e ngā marara wai ethyl cellulose ngā mōrearea haumaru o ngā whakarewa waro toenga, me te whakahohe hoki i ngā reiti tukunga rongoā whakahaeretia.
3.4. Ngā Rauemi Hiko me ngā Paninga Mahi
I roto i ngā rauemi takai hiko me ngā kiriata mahi, ka taea e ngā marara wai ethyl cellulose te mahi hei matrices hanga kiriata, e whakarato ana i ngā āhuatanga miihini me te pumau wera pai rawa atu. Ka taea hoki te whakakotahi me ngā rauemi nano hei hanga kiriata mārama, kiriata kawe hiko rānei.
4. Ngā Whakatūpato me ngā Auahatanga Whakawhanake
Mana Pūmau: Ka pāngia ngā marara wai e te pāmahana, te pH, me ngā irahiko. Nō reira, me whiriwhiri ngā marara me ngā tikanga rokiroki e tika ana i runga i te whakamahinga motuhake.
Te Mahi Whakamaroke i te Kiriata: Tērā pea ka pakaru te paninga i te nui rawa o te mimiti o te wai. Me whakapai ake te kounga o te paninga mā te tāpiri atu, mā te arotau rānei i ngā tukanga.
Kakariki me te Mahi-Teitei: I te heke mai, ka whanake ngā marara wai o te ethyl cellulose ki te taumata totoka teitei, ki te VOC iti, me te mahi (pēnei i te ātete ahi, te ātete wai, me te kawe hiko) hei whakatutuki i ngā hiahia ahumahi me te hauora teitei ake.
Ngā pūtau etilaHe rauemi wai-whakarewa pai mō te taiao, he rauemi wai-whakarewa teitei te mahi, e whakakotahi ana i ngā āhuatanga hanga kiriata pai o te ethyl cellulose me ngā painga matomato o ngā pūnaha wai-whakarewa. Ehara i te mea he whai hua noa iho i roto i ngā ahumahi tuku iho pēnei i ngā paninga, waituhi, me ngā rongoā, engari e whakaatu ana hoki i te kaha ki roto i ngā mara hou pēnei i te hikohiko me ngā paninga mahi. I te rongonuitanga o ngā ariā matū matomato me te whanaketanga o te hangarau rauemi wai-whakarewa, ka noho te ethyl cellulose wai-whakarewa hei huarahi whanaketanga nui i roto i te mara rauemi ā muri ake nei.
