He rauemi hanga whare te moata maroke, he mea hanga mai i te onepu, te sima me ētahi atu tāpiringa. Ka whakamahia hei hono i ngā pereki, ngā poraka me ētahi atu rauemi hanga whare hei hanga hanganga. Heoi, ehara i te mea ngāwari te mahi tahi me te moata maroke nā te mea ka ngaro te wai, ā, ka tere rawa te mārō. I ētahi wā ka tāpirihia ngā cellulose ethers, inā koa te hydroxypropylmethylcellulose (HPMC) me te methylhydroxyethylcellulose (MHEC), ki te moata maroke hei whakapai ake i ōna āhuatanga pupuri wai. Ko te kaupapa o tēnei tuhinga he tūhura i ngā painga o te whakamahi i te cellulose ether i roto i te moata maroke, me pēhea hoki e taea ai te whakapai ake i te kounga o te hanga.
Te pupuri wai:
He mea nui te pupuri wai ki te kounga o te moata maroke. Me pupuri te nui o te makuku kia tika ai te whakatō o te moata, kia kaha ai te hononga i waenga i ngā rauemi hanga. Heoi, ka tere te ngaro o te makuku o te moata maroke, inā koa i ngā āhuatanga wera, maroke, ā, ka hua ake he moata kounga iti. Hei whakaoti i tēnei raruraru, ka tāpirihia ētahi atu cellulose ethers ki te moata maroke hei whakapai ake i ōna āhuatanga pupuri wai.
Ko ngā cellulose ethers he pūhui i ahu mai i te cellulose, te muka tūturu e kitea ana i roto i ngā tipu. Ko te HPMC me te MHEC he momo cellulose ethers e rua e tāpirihia ana ki ngā moata maroke hei whakapai ake i te pupuri wai. Ka mahi rāua mā te hanga i tētahi matū rite ki te tiēre ina konatunatua ki te wai, ka āwhina i te whakaroa i te tukanga whakamaroke o te moata.
Ngā painga o te whakamahi i te cellulose ether i roto i te moata maroke:
He maha ngā painga o te whakamahi i ngā etera cellulose i roto i te moata maroke, tae atu ki:
1. Whakapai ake i te ngāwari o te mahi: Ka taea e te cellulose ether te whakapai ake i te ngāwari o te mahi o te moata maroke mā te whakaiti i tōna pakari me te whakanui ake i tōna ngāwari. Mā tēnei ka māmā ake te pania o te moata ki te rauemi hanga kia pai ake ai te āhua.
2. Te whakaiti i te pakaru: Ka pakaru pea te moata maroke ina maroke wawe rawa, ka ngoikore tōna kaha. Mā te tāpiri i te cellulose ether ki te ranunga, ka puhoi ake te maroke o te moata, ka whakaiti i te tūponotanga o te pakaru, ka whakanui ake hoki i tōna kaha.
3. Te kaha o te here: He mea nui te kaha o te here o te moata maroke ki ngā rauemi hanga whare mō tōna mahi. Ka whakanui ake ngā cellulose ethers i te pupuri wai o te moata, ka whakanui ake i tōna kaha here, ka hua ake he here kaha ake, he roa ake te mau.
4. Whakapai ake i te pakari: Ka taea e te cellulose ether te whakapai ake i te pakari o te moata maroke mā te whakaiti i te nui o te wai e ngaro ana i te wā whakamaroke. Mā te pupuri i te nui o te wai, ka iti ake te tūponotanga o te moata ki te pakaru, ki te pakaru rānei, ka roa ake te hanganga.
He mea nui te moata maroke mō te hanga whare. Heoi, he uaua ki te whakahaere i ōna āhuatanga pupuri wai, ā, ka hua ake he moata kounga iti. Mā te tāpiri i ngā cellulose ethers, inā koa ko te HPMC me te MHEC, ki te moata maroke ka taea te whakapai ake i tōna mahi pupuri wai, ā, ka hua ake he hua kounga teitei ake. Ko ngā painga o te whakamahi i ngā cellulose ethers ki ngā moata maroke ko te whakapai ake i te mahi, te whakaiti i te pakaru, te whakapai ake i te kaha o te here me te whakanui ake i te roa. Mā te whakamahi i ngā cellulose ethers ki te moata maroke, ka taea e ngā kaihanga te whakarite kia kaha, kia roa, kia ataahua hoki ō rātou hanganga.
