Methyl hydroxyethyl cellulose (MHEC)He matū kore-ionic cellulose ether tēnei, he pai ki te whakamātotoru, te pupuri wai, te hanga kiriata me te ngāwari ki te mahi. He mea tino nui tana mahi i roto i ngā pūnaha moata maroke-whakaranu o te hanga whare hou. He whānuitia te whakamahinga i roto i ngā momo hua pēnei i te moata pereki, te moata paraikete, te piripiri taera, te moata whakaōrite-ake sima me te moata whakamahana wera, ka taea te whakapai ake i te mahi a te moata me te whakapai ake i te kounga me te whai huatanga o te hanga.
1. Whakapai ake i te pupuri wai o te moata
Ko tētahi o ngā mahi tino nui a te MHEC ko tōna mahi pupuri wai tino pai. I te wā o te hanga moata, me tautoko wai ngā rauemi sima pēnei i te sima, te gypsum rānei i roto i te tauhohenga whakapakeke, engari he kaha te mimiti wai o te paparanga turanga, ka tere te mimiti i te wai i roto i te moata, ka puta te ngaronga wai wawe i roto i te moata, ā, ka pā ki te ahunga whakamua katoa o te tauhohenga whakamakuku. Ka hangaia e te MHEC he hanganga mata toru-ahu kua tohatohahia i roto i te moata, ka mau tonu te makuku, ka ārai i te mimiti o te makuku e te paparanga turanga, e te hau rānei, ā, ka mau tonu te mahi a te moata mō te wā roa. He mea nui tēnei pānga pupuri wai hei whakaroa i te wā hanga, hei whakapai ake i te whanaketanga kaha me te ārai i te pakaru.
2. Whakapai ake i te mahi hanga me te āhua whakahaere
Hei whakamātotoru whai hua, ka taea e te MHEC te whakapai ake i te ōritetanga me ngā āhuatanga thixotropic o te moata, kia pai ai te mahi hanga o te moata. I roto i te tukanga hanga pēnei i te parai me te whariki, he maeneene te mata o te moata kei roto te MHEC, he ngāwari ki te hora, kāore e piri ki te maripi, ā, he pai hoki ngā āhuatanga ārai-totoka. Ina koa i te wā e hanga ana i runga i ngā mata poutū, kāore te moata e ngawari ki te paheke ki raro, he mea watea mō te whakahaere i te matotoru o te paninga me te whakapai ake i te whai huatanga o te hanga. Hei tāpiri, ko ngā āhuatanga whakahinuhinu o te MHEC ka whakarei ake i te mahi a te moata, ka whakaiti i te kaha tinana o ngā kaimahi hanga, ā, ka whakapai ake i te whakamarie o te hanga.
3. Te hononga whakapakari
Ahakoa ehara te MHEC i te piripiri, ka āwhina i te sima, i ētahi atu rauemi piri rānei kia pai ake te hono atu ki te turanga mā te whakapai ake i te mākū o te moata me te whakaroa i te wā tuwhera, ā, mā te pera ka whakapai ake i te kaha piri o te moata ki te turanga, ki ngā pereki, ki ngā taera me ētahi atu rauemi. Ina koa i roto i ngā piripiri taera me ngā kaihoko hononga, ka taea e te MHEC te hanga i tētahi kiriata piripiri ōrite me te haere tonu, ka taea ai e te rauemi te piri kaha ake ki te turanga, ka whakapai ake i te mahi piri me te pumau o te pūnaha whānui.
4. Whakahaerehia te wā whakatakoto me te wā whakapakeke o te moata
Ka taea e te MHEC te whakaroa i te tukanga whakamakuku o te sima, te gypsum rānei i roto i te moata, ā, ka roa ake te wā whakatakoto o te moata. He tino pai tēnei mō te hanga i roto i te taiao pāmahana teitei, maroke rānei, ā, ka taea te ārai i ngā raruraru hanga e puta mai ana i te tere rawa o te whakatakoto, pērā i te pakaru o te mata me te ngoikore o te hononga. Mā te whakarerekē tika i te nui o te MHEC i tāpirihia, ka taea te whakahaere tika i te wā mahi o te moata kia tutuki ai ngā whakaritenga hanga o ngā tukanga rerekē.
5. Whakapai ake i te ātete pakaru me te roa o te moata
Nā te mea ka whakapai ake te MHEC i te pupuri wai me te ngāwari o te moata, ka whakaiti i te mimiti me te ngaronga wawe o te wai, ka taea e ia te aukati i te putanga mai o ngā kapiti mimiti me te whakapai ake i te ātete kapiti me te roa o te moata i te wā e whakamahia ana mō te wā roa. I roto i ngā pūnaha whakamarumaru pakitara o waho, i ngā whare ātete rū whenua rānei, he mea tino nui tēnei mahi, ā, ka whai wāhi ki te pumau me te roa o te ora o te hanganga.
6. He hototahitanga kaha ki te pūnaha moata
He pai te hototahitanga o te MHEC ki ngā momo rauemi sima pēnei i te sima, te raima, te gypsum, me ētahi atu tāpiringa (pēnei i te paura rapa ka taea te whakamarara anō, te whakaiti wai, te kaihoko ārai huka, me ētahi atu). Mā tēnei ka taea te whakamahi ngāwari ki ngā pūnaha moata mahi maha, kāore e ngāwari ki ngā tauhohenga matū, ki ngā taupatupatu mahi rānei, ā, ka nui ake te herekoretanga mō ngā hanganga moata maroke-whakaranu.
7. Te urutau me te pumau o te taiao
He kaha te urutau o te MHEC ki te pH me te pāmahana, he pumau pai i roto i ngā taiao waikawa, kūpapa, ngoikore rānei, ā, ka taea te pupuri i te ōritetanga pai me te pupuri wai ahakoa i roto i ngā taiao hanga pāmahana teitei. Nā tēnei āhuatanga ka taea te whakamahi whānui i roto i ngā pūnaha moata i roto i ngā rohe āhuarangi rerekē, inā koa i roto i te hanganga raumati.
He maha ngā āhuatanga o te whakarerekētanga o te Methyl hydroxyethyl cellulose (MHEC)tūranga i roto i te moata. Ka whakaratohia he otinga pono ake, he whai hua ake, he ngāwari ake hoki te whakahaere mō te hanga mā te whakapai ake i te pupuri wai, te whakapai ake i te mahi, te whakarei ake i te piri, te whakatikatika i te wā whakatakoto me te whakapai ake i te ātete me te pakari o te pakaru. I te tere o te whanaketanga o ngā rauemi hanga matomato me ngā moata kua whakaranua, ka nui haere te tūranga o te MHEC, ka noho hei kaihoko āwhina tino nui, tino hira hoki i roto i ngā hanganga moata mahi-teitei.
