Te rerekētanga tauira Hydroxypropyl methylcellulose

Hydroxypropyl methyl celluloseE rua ngā momo wai matao wera-rewa noa.

1. Raupapa Gypsum I roto i ngā hua raupapa gypsum, ko ngā cellulose ethers te nuinga o te wā e whakamahia ana hei pupuri i te wai me te whakanui ake i te maeneene. Ka whakaratohia e rāua he whakamarie. Ka taea e ia te whakaoti i ngā feaa mō te pakaru o te pahu me te kaha tuatahi i te wā o te tukanga tono, me te whakaroa i te wā mahi.

2. I roto i te putty o ngā hua sima, ko te mahi matua a te cellulose ether ko te pupuri wai, te piri me te maeneene, te aukati i ngā kapiti me te maroke i puta mai i te nui o te ngaronga wai, ā, ka whakapakari ngātahi i te piri o te putty me te whakaiti i te putanga o te tukanga hanga. Ka whakaheke i te āhuatanga, ā, ka maeneene ake te hanga.

3. I roto i te umanga paninga peita rapa, ka taea te whakamahi i ngā etera cellulose hei kaihanga kiriata, hei whakamātotoru, hei whakaemulsifier me hei whakaū, kia pai ai te ātete ki te kakahu, kia ōrite te mahi paparanga, kia piri me te uara PH, ā, kia pai ake ai te mānukanuka o te mata. He pai hoki te mahi ina konatunatua ki ngā whakarewa waro, ā, nā te nui o te pupuri wai ka pai ai mō te paraihe me te whakataurite.

4. Ko te kaihoko atanga te nuinga e whakamahia ana hei whakamātotoru, ka taea te whakapai ake i te kaha kume me te kaha kutikuti, te whakapai ake i te paninga mata, me te whakarei ake i te kaha piri me te here.

5. Ko te etera cellulose i roto i tēnei pepa e arotahi ana ki te here me te whakanui ake i te kaha, kia māmā ake ai te paninga o te moata, kia pai ake ai hoki te mahi. Mā te pānga ārai-totoka, te mahi pupuri wai nui ake ka roa ake te wā mahi o te moata, ka pai ake te ātete ki te whakapoto me te ngatata, ka whakapai ake i te rahinga o te mata, ā, ka pai ake te kaha o te here.

6, Ngā uku honikoma I roto i ngā uku honikoma hou, he maeneene, he pupuri wai, he kaha hoki te hua.

7. Mā te nui haere o te hiri, te tuitui cellulose ether ka pai te piri o te taha, ka iti te tere whakaheke me te ātete kakahu teitei, ā, ka tiakina ngā raraunga taketake mai i te kino miihini, ka ārai i te pānga o te rumaki ki ngā hanganga katoa.

8. Mā te piri pūmau o te cellulose ether whakaōrite-ake e whakarite ana i te rere pai me te kaha whakaōrite-ake, ā, mā te tere pupuri wai whakahaere ka taea e ia te whakatakoto tere me te whakaiti i te pakaru me te whakapoto.

9. He nui te pupuri wai o te moata parai hangahanga hei whakamakuku i te sima, hei whakanui ake i te kaha o te here, ā, i te wa ano ka whakanui ake i te kaha kume me te kaha kutikuti, ka tino whakapai ake i te hua hangahanga me te pai o te mahi.

10. Nā te kaha o te piri o te taera ki te pupuri i te wai, kāore e hiahiatia kia pania, kia whakamakuku rānei ngā taera me te paparanga turanga, ka nui ake te kaha o te piri. He roa te wā hanga o te paru, he pai, he ōrite te hanganga, he watea te hanganga, ā, he tino pai te ārai i te hekenga.
