1. He pumau ki te waikawa me te kawakore, ā, he tino pumau tōna wairewa i te awhe pH=2~12. Kāore he pānga nui o te houra kautika me te wai raima ki tōna mahi, engari ka taea e te kawakore te tere ake i tōna tere whakarewa me te whakanui ake i tōna matotoru.
2. He matū pupuri wai tino whai hua te HPMC mō te pūnaha moata paura maroke, ka taea te whakaiti i te tere toto me te taumata paparanga o te moata, te whakapai ake i te piri o te moata, te aukati i te hanganga o ngā kapiti kirihou i roto i te moata, me te whakaiti i te taupū pakaru kirihou o te moata.
3. He irahiko kore-ionic me te kore-polymeric, he tino pumau i roto i ngā otinga wai kei roto ngā tote whakarewa me ngā irahiko waro, ā, ka taea te tāpiri ki ngā rauemi hanga mō te wā roa kia pai ake ai tōna pakari.
4. Kua tino pai ake te mahi a te moata. Te āhua nei he "hinu" te moata, ka taea e ia te whakakī i ngā hononga pakitara, te whakangawari i te mata, te whakapūmau i te hononga o te moata me te paparanga turanga, me te whakaroa i te wā mahi.
te pupuri wai
Te whakatutuki i te tiaki ā-roto, he mea e whai hua ana ki te whakapai ake i te kaha mō te wā roa
Ārai i te toto, ārai i te taunga me te mimiti o te moata
Whakapai ake i te ātete ki te pakaru o te moata.
whakamātotoru
Ārai i te wehewehenga, whakapai ake i te ōritetanga o te moata
Ka whakapai ake i te kaha o te here mākū, ā, ka ātete hoki ki te totohu.
hau totohu
Whakapai ake i te mahi a te moata
I te mea ka piki ake te matotoru o te cellulose, ka roa ake hoki te mekameka ngota ngota, ka kitea ake te pānga hopu-hau.
Te whakaroa
Ka mahi tahi me te pupuri wai hei whakaroa i te wā tuwhera o te moata.
Māngaro Hydroxypropyl Ether
1. Ko te nui ake o te hydroxypropyl i roto i te māngaro ether ka whakawhiwhia te pūnaha ki te hydrophilicity pumau, ka hanga te wai kore utu hei wai here, ā, ka whai wāhi nui ki te pupuri wai.
2. He rerekē te kaha o ngā māngaro etera, he rerekē te nui o te hydroxypropyl, ki te āwhina i te cellulose ki te pupuri wai i raro i te horopeta kotahi.
3. Mā te whakakapinga o te rōpū hydroxypropyl ka whakanui ake i te tohu whānui i roto i te wai, ka pēhia hoki te wāhi rere o ngā matūriki, ā, ka whakanui ake i te matotoru me te pānga matotoru.
Te hinu whakahinuhinu Thixotropic
Ka whakarerekē te tere o te marara o te māngaro etera i roto i te pūnaha moata i te rheology o te moata, ā, ka whakawhiwhia ki te thixotropy. Ina pāngia he kaha o waho, ka heke te matotoru o te moata, ka whakarite kia pai te mahi, te papu, me te tautoko. Ina tangohia te kaha o waho, ka piki ake te matotoru, kia pai ai te mahi ārai-totoka me te ārai-totoka o te moata, ā, i roto i te paura putty, he painga ki te whakapai ake i te kanapa o te hinu putty, te kanapa oro, me ētahi atu.
Te pānga o te pupuri wai āwhina
Nā te pānga o te rōpū hydroxypropyl i roto i te pūnaha, he āhuatanga hydrophilic tō te māngaro ether. Ina honoa ki te cellulose, ki te tāpiri rānei ki tētahi nui o te moata, ka taea te whakanui ake i te pupuri wai ki tētahi taumata, ā, ka whakapai ake i te wā whakamaroke o te mata.
Ārai-totoka me te ārai-paheke
He pānga pai rawa atu mō te ārai-totoka, te pānga hanga
Paura rapa ka taea te whakamarara anō
1. Whakapai ake i te mahi a te moata
Ka marara ngā matūriki paura rapa ki roto i te pūnaha, ka pai ake te rere o te pūnaha, ka pai ake te mahi me te ngāwari o te mahi o te moata.
2. Whakapai ake i te kaha o te here me te piripono o te moata
I muri i te whakamararatanga o te paura rapa ki roto i te kiriata, ka honoa ngā mea kore-waro me ngā mea waro i roto i te pūnaha moata. Ka taea te whakaaro ko te onepu sima i roto i te moata te angaanga, ā, ko te paura rapa te mea e hanga ana i te hononga i roto, e whakanui ana i te piri me te kaha. Ka hangaia he hanganga ngāwari.
3. Whakapai ake i te ātete huarere me te ātete huka-rewa o te moata
He kapia kirihou whakamahana te paura rapa, he ngāwari hoki, ka taea e ia te āwhina i te moata kia tū atu i ngā huringa makariri me te wera o waho, ā, kia kore ai e pakaru te moata i ngā huringa pāmahana.
4. Whakapai ake i te kaha piko o te moata
He pai te whakakotahitanga o te polymer me te whakapiri sima. Ina puta ngā kapiti i te kaha o waho, ka taea e te polymer te whiti i ngā kapiti me te aukati i te whānui o ngā kapiti, kia pai ake ai te pakari o te pakaru me te āhua o te moata.
