1. Te wera o te wai
E ai ki te pihi tukunga o te wera o te whakamakuku i roto i te wā, e rima ngā wāhanga o te tukanga whakamakuku o te sima, arā, ko te wā whakamakuku tuatahi (0~15 meneti), te wā whakaoho (15 meneti~4 haora), te wā whakatere me te wā whakatakoto (4 haora~8 haora), te wā whakaheke me te wā whakapakeke (8 haora~24 haora), me te wā whakamaroke (1 rā~28 rā).
E whakaatu ana ngā hua o te whakamātautau i te wā tōmua o te whakaurunga (arā, te wā whakamakuku tuatahi), ina 0.1% te nui o te HEMC ki te whakataurite ki te paru sima pātea, ka piki ake te tihi werawera o te paru, ā, ka tino piki ake te tihi. Ina te nui oHEMCKa piki ake ki te Ina neke atu i te 0.3%, ka whakaroahia te tihi wera tuatahi o te para, ā, ka heke haere te uara tihi me te pikinga o te ihirangi HEMC; ka whakaroahia e te HEMC te wā whakaoho me te wā whakaterenga o te para sima, ā, ki te nui ake te ihirangi, ka roa ake te wā whakaoho, ka hoki whakamuri te wā whakaterenga, ā, ka iti ake te tihi wera; kāore he pānga mārama o te huringa o te ihirangi cellulose ether ki te roa o te wā whakahekenga me te wā pumau o te para sima, e whakaaturia ana i te Pikitia 3(a). E whakaaturia ana ka taea hoki e te cellulose ether te whakaiti i te wera o te whakamakuku o te whakapiri sima i roto i ngā haora 72, engari ki te roa ake te wera o te whakamakuku i te 36 haora, he iti noa te pānga o te huringa o te ihirangi cellulose ether ki te wera o te whakamakuku o te whakapiri sima, pērā i te Pikitia 3(b).

2. Mngā āhuatanga hangarau：
Mā te ako i ngā momo etera cellulose e rua me ngā matotoru o te 60000Pa·s me te 100000Pa·s, i kitea ko te kaha pēhi o te moata whakarerekētia i konatunatua ki te etera methyl cellulose i heke haere i te pikinga o tōna ihirangi. Ko te kaha pēhi o te moata whakarerekētia i konatunatua ki te matotoru hydroxypropyl methyl cellulose ether 100000Pa·s ka piki tuatahi, kātahi ka heke i te pikinga o tōna ihirangi (e whakaatuhia ana i te Pikitia 4). E whakaatu ana ko te whakaurunga o te etera methyl cellulose ka tino whakaiti i te kaha pēhi o te moata sima. Ko te nui ake o te rahinga, ko te iti ake o te kaha; ko te iti ake o te matotoru, ko te nui ake o te pānga ki te ngaronga o te kaha pēhi o te moata; hydroxypropyl methyl cellulose ether Ina iti iho te horopeta i te 0.1%, ka taea te whakanui ake i te kaha pēhi o te moata. Ina neke atu te horopeta i te 0.1%, ka heke te kaha pēhi o te moata i te pikinga o te horopeta, nō reira me whakahaere te horopeta ki te 0.1%.

(Methyl cellulose ether, matotoru 60000Pa·S, ka kiia i muri nei ko MC1; methyl cellulose ether, matotoru 100000Pa·S, ka kiia ko MC2; hydroxypropyl methylcellulose ether, matotoru 100000Pa·S, ka kiia ko MC3).
3. Cwā tuku rota：
Mā te ine i te wā whakatakoto o te hydroxypropyl methylcellulose ether me te matotoru o te 100000Pa·s i roto i ngā horopeta rerekē o te whakapiri sima, i kitea ko te pikinga ake o te horopeta HPMC, ka roa ake te wā whakatakoto tuatahi me te wā whakatakoto whakamutunga o te moata sima. Ina 1% te kukū, ka eke te wā whakatakoto tuatahi ki te 510 meneti, ā, ka eke te wā whakatakoto whakamutunga ki te 850 meneti. Ki te whakatauritea ki te tauira kau, ka roa ake te wā whakatakoto tuatahi mā te 210 meneti, ā, ka roa ake te wā whakatakoto whakamutunga mā te 470 meneti (e whakaatuhia ana i te Pikitia 5). Ahakoa he HPMC me te matotoru o te 50000Pa s, 100000Pa s, 200000Pa s rānei, ka taea te whakaroa i te whakatakoto o te sima, engari ki te whakatauritea ki ngā cellulose ether e toru, ka roa ake te wā whakatakoto tuatahi me te wā whakatakoto whakamutunga mā te pikinga ake o te matotoru, e whakaatuhia ana i te Pikitia 6. Nā te mea ka piri te cellulose ether ki te mata o ngā matūriki sima, ka ārai i te wai kei pā ki ngā matūriki sima, ā, ka whakaroa i te makuku o te sima. Ka nui ake te matotoru o te cellulose ether, ka matotoru ake te paparanga piri ki te mata o ngā matūriki sima, ā, ka nui ake te pānga whakaroa.

(MC-5(50000Pa·s), MC-10(100000Pa·s) me MC-20(200000Pa·s))
Mā te methyl cellulose ether me te hydroxypropyl methyl cellulose ether ka roa ake te wā whakatakoto o te paru sima, ka taea ai te whakarite kia nui te wā me te wai o te paru sima mō te tauhohenga wai, ā, ka whakatau i te raruraru o te kaha iti me te wāhanga mutunga o te paru sima i muri i te whakapakeketanga.
4. Te pupuri wai:
I rangahauhia te pānga o te nui o te cellulose ether ki te pupuri wai. I kitea ko te pikinga ake o te nui o te cellulose ether, ka piki ake te tere pupuri wai o te moata, ā, ina nui ake te nui o te cellulose ether i te 0.6%, ka pumau tonu te tere pupuri wai. Heoi, ina whakaritea ngā momo cellulose ether e toru (HPMC me te matotoru o te 50000Pa s (MC-5), 100000Pa s (MC-10) me te 200000Pa s (MC-20)), he rerekē te awe o te matotoru ki te pupuri wai. Ko te whanaungatanga i waenga i te tere pupuri wai ko: MC-5.
