Te taumata rauemi hanga wharete etera cellulosehe tāpiri matū mahi nui, e whakamahia whānuitia ana i roto i ngā rauemi hanga, pērā i te sima, te raima, te moata maroke, me ētahi atu.
1. Hanganga matū me te whakarōpūtanga
He matū pūmua te cellulose ether i hangaia mā te whakarerekētanga matū o te cellulose tūturu. Ko tōna wāhanga matua ko te rōpū hydroxyl o te cellulose i whakarerekētia e te kaihoko etherifying (pērā i te vinyl chloride, te waikawa acetic, me ētahi atu). E ai ki ngā rōpū etherifying rerekē, ka taea te wehewehe ki ngā momo cellulose ethers rerekē, ko te nuinga ko te hydroxypropyl methylcellulose (HPMC), te hydroxyethyl cellulose (HEC) me te methyl cellulose (MC).
2. Te pupuri wai
He tino pai ngā āhuatanga pupuri wai o te cellulose ether kounga rauemi hanga, ka taea ai e tēnei te whakapai ake i te kaha pupuri wai o te moata me te raima. Ka whakarei ake tēnei i te mahi a te rauemi i te wā hanga, ā, ka whakaiti i te ngatata me te ngaronga kaha e puta mai ana i te mimiti wai.
3. Te Whakamātotoru
He pai ngā āhuatanga whakamātotoru o te cellulose ether, ka taea te whakapai ake i te rere me te matotoru o ngā rauemi hanga, kia māmā ake ai te whakahaere i a rātou i te wā hanga. Ka āwhina te whakamātotoru ki te whakapai ake i te pumau o te rauemi, ā, ka ārai i te paparanga me te whakatō.
4. Te whakaiti i te wai
Ki tētahi taumata,ngā etera celluloseka taea te whakaiti i te nui o te wai i roto i te raima, i te moata rānei, ā, ka whakapai ake i te kaha me te roa o te rauemi. Nā tēnei āhuatanga i tino hira ai i roto i te whakamahinga o te raima mahi-teitei.
5. Te mahi hanga
He pai ake te mahi a ngā rauemi hanga me ngā cellulose ethers i te wā hanga, ka taea ai te whakaroa i te wā hanga me te whakaiti i ngā raruraru hanga e puta mai ana i te maroke. Hei tāpiri, ka taea hoki e rātou te whakapai ake i te piri o te moata me te whakarei ake i te piri o ngā rauemi paninga.
6. Ātete pakaru
Ka taea e ngā cellulose ethers te whakapai ake i te ātete ki ngā pakaru o te moata me te raima, me te whakaiti i ngā pakaru i puta mai i ngā huringa pāmahana, i te mimiti maroke rānei. He mea nui tēnei mō te pumau me te ataahua o ngā whare mō te wā roa.
7. Te urutau me te hototahi
He pai te hototahitanga o ngā cellulose ethers kounga rauemi hanga ki ngā momo rauemi hanga, ā, ka taea te whakaranu ki te sima, te gypsum, ngā polymer me ētahi atu kai, me te kore e pā ki tā rātou mahi. Nā tēnei ngāwari ki te urutau ka whakamahia whānuitia ngā cellulose ethers i roto i te umanga hanga.
8. Te tiaki i te taiao
Mai i ngā rauemi mata ongā etera cellulosei ahu mai i ngā muka tipu, he āhuatanga tiaki taiao anō hoki ō rātou. Ki te whakatauritea ki ētahi pūmua hangai, he pai ake te whakamahi me te tukatuka para i te cellulose ether hei whakamahi mā te taiao.
9. Ngā āpure tono
He whānuitia te whakamahinga o te cellulose ether kounga rauemi hanga whare i roto i ngā momo rauemi hanga whare, tae atu ki:
Moata maroke: pērā i te moata honohono, te moata paninga, me ētahi atu.
Konukura: inā koa ko te konukura mahi-teitei.
Paninga: ka taea te whakamahi mō ngā paninga pakitara o roto, o waho hoki, peita rapa, me ētahi atu.
Ngā hua gypsum: pērā i te papa gypsum me te putty gypsum.
10. Ngā Whakatūpato mō te Whakamahinga
I te whakamahi i te cellulose ether kounga rauemi hanga, me whakarongo koe ki ngā āhuatanga e whai ake nei:
Tāpirihia kia rite ki te ōwehenga kua tūtohutia. Ki te nui rawa, ki te kore rānei e ranea, ka pā ki te mahi whakamutunga.
Kia rite te ranunga i te wā e whakaranu ana kia kore ai e haaputuputu.
I te wā e penapena ana, kia tūpato ki te ātete ki te makuku kia kore ai e pupū ake, e kohikohi rānei.
Kua noho te cellulose ether kounga rauemi hanga hei tāpiringa tino nui i roto i te umanga rauemi hanga nā ōna āhuatanga ahurei me te whānui o te whakamahinga. Mā te whakapai tonu i ngā whakaritenga a te umanga hanga mō te mahi rauemi, ka whānui ake ngā tūmanakohanga tono mō te cellulose ether.
