He whanaketanga nui te whakamahinga o ngā etera cellulose i roto i te moata pereki me te moata parai i roto i ngā hangarau hanga whare hou. Ehara i te mea ka taea anake te whakapai ake i te mahi hanga me te mahi piri o te moata, engari ka whakapai ake hoki i tōna pupuri wai, tōna ngāwari ki te mahi me ōna āhuatanga ārai-totoka, ā, ka tino whakapai ake i te pai o te hanga me te kounga o te whare.
1. Te whakamāramatanga me ngā momo o ngā etera cellulose
Ko ngā etera cellulose he momo pūhui pūmua kore-ionic, ionic rānei i hangaia mā te whakarerekētanga matū o te cellulose tūturu. He pai te wairewatanga ki te wai, ā, he pai hoki ōna āhuatanga hanga kiriata, ā, he maha ngā wā e whakamahia ana i roto i te hanga whare, te rongoā, te kai, ngā matū o ia rā me ētahi atu mara. I roto i te hanga moata, ko ngā etera cellulose e whakamahia whānuitia ana ko:
Te Hydroxypropyl methylcellulose (HPMC)
Methyl hydroxyethyl cellulose (MHEC)
Ko te HPMC te mea e whakamahia whānuitia ana i roto i te mahi pereki me te moata parakimete nā te mea he pai te pupuri i te wai, he pumau te pāmahana, ā, he tino pai te mahi hanga.
2. Te tūranga o te cellulose ether i roto i te moata pereki
Ka whakamahia te moata pereki hei hono i ngā rauemi pereki pēnei i te pereki me te kōhatu. Me pai te piri o te moata, me te pupuri wai hoki kia kore ai e mimiti wawetia te makuku e ngā pereki i te wā hanga, ā, ka pā ki te pānga o te piri.
Whakapai ake i te pupuri wai
He pai te kaha o te cellulose ether ki te pupuri i te wai, ā, ka taea e ia te hanga i tētahi kiriata angiangi i roto i te moata hei pupuri i te makuku, hei ārai hoki i te mimiti tere o te makuku i te wā e hangaia ana te moata. Mā tēnei ka āwhina i te sima kia tino makuku, kia pai ake ai te kaha me te piri o te moata.
Whakapai ake i te mahi hanga
I muri i te tāpiri i te cellulose ether, ka nui ake te hinu whakahinuhinu me te maeneene o te moata pereki, ka pai te āhua hanga, ā, ka whakaitihia ngā raruraru kounga pērā i te poka me te ngatata.
Whakapai ake i te mahi honohono
Mā te pai o te pupuri i te wai me te matotoru ka māmā ake te piri o te moata ki te mata o ngā pereki me ngā kōhatu, kāore e ngawari ki te taka atu, ā, ka pai ake te mahi a te mahi pereki.
3. Te tūranga o te cellulose ether i roto i te moata parai
Ko te moata pāreti te mea e whakamahia nuitia ana mō te whakataurite me te whakapaipai i ngā pakitara o te whare, ā, he nui ake ngā whakaritenga mō te mahi hanga me te kounga o te mata.
Whakahaerehia te tere whakamakuku sima
I roto i te moata paraikete, ka taea e te cellulose ether te whakaroa i te ngaronga o te wai, me te whakaoti i te makuku o te sima, ā, ka whakanui ake i te kaha me te whakaiti i ngā kapiti mimiti.
Ārai i te totohu me te whakapai ake i te mahi hanga o te mata
Nā te pai o te pānga whakamātotoru o te cellulose ether, ka taea e ia te ārai i te totohu o te moata paraikete ina hangaia ki runga i te mata poutū, ka pai ake te whakahaere.
Whakapai ake i te ngāwari o te mahi
Mā te cellulose ether ka māmā ake te whakangawari me te whakaoti i te moata pāreti, ka pai ake te whai huatanga o te hanga me te kounga o te mata, ā, ka maeneene ake, ka ngawari ake hoki te mata.
Te ātete pakaru kua whakarei ake
Mā te pupuri i te wai me te ngāwari e āwhina ki te whakapakari i te ātete ki ngā pakaru o te paparanga raima, me te whakaiti i te tūponotanga o te ngatata me te taka.
4. Ngā āhuatanga e pā ana ki te mahi a te cellulose ether
He hononga tata te mahi a te cellulose ether ki tōna hanganga matū, te taumata o te whakakapinga (DS), te matotoru, te rahi o te matūriki me ētahi atu āhuatanga. Ina koa:
Te nui o te whakakapinga:ka pā ki tōna wairewatanga wai me te tere whakarewatanga. I te nuinga o te wā, he pai ake te taumata whakakapinga i waenga i te 1.4 me te 1.9 mō ngā kaupapa hanga.
Te matotoru:e whakatau ana i tōna pānga whakamātotoru i roto i te moata, ā, ko te awhe matotoru e whakamahia whānuitia ana ko te 400~100,000 mPa·s.
Rahi o te matūriki:ka pā ki tōna mararatanga me te tere whakarewatanga. Ka iti ake te rahi o te matūriki, ka tere ake tōna rewatanga.
5. Te horopeta me ngā tūpato e tika ana
I roto i te moata pereki me te moata parai, ko te nui o te cellulose ether e tāpirihia ana ka whakahaeretia i te nuinga o te wā ki te 0.1%~0.4% (i runga i te taumaha o te sima, o ngā rauemi sima rānei). Me aro ki:
Whakaranua kia ōrite te ranunga kia kore ai e haaputuputu;
Kia tupato ki te pāmahana me te wā whakarewa o te cellulose ether;
He rerekē rawa te mahi a ngā etera cellulose o ngā waitohu me ngā taumata matotoru rerekē, ā, me whakatau te ōwehenga pai rawa atu mā roto i ngā whakamātautau.
Hei tāpiringa me te mahi tino pai,te etera cellulosekua tino whakapai ake i te mahi whānui o te moata pereki me te moata parai, kia pai ake ai te hanga me te pono ake o te kounga. I te whanaketanga o ngā rauemi hanga matomato, ka piki haere tonu te hiahia mō ngā etera cellulose e pai ana ki te taiao me te mahi teitei. I roto i ngā mahi mahi, ko te whiriwhiri i te momo me te tauira tika o te etera cellulose me te whakahaere pūtaiao i tōna horopeta te mea nui ki te whakarite kia tutuki te mahi a te moata i ngā paerewa.
