Hydroxypropylmethylcellulose
Neke atu i te 95% o te taumata hangahangahydroxypropyl methylcellulosee whakamahia ana i roto i te moata paura putty. Ko āna mahi he whakamātotoru, he pupuri wai, me te hanga. Mā te mahi pupuri wai o te HPMC ka ārai i te pakaru o te paru nā te tere o te maroke i muri i te paninga, ka whakarei ake i te kaha i muri i te whakapakeketanga, ko te mahi matua ko te pupuri wai, te whakamātotoru, me ngā pānga ārai-totoka. Ka taea te whakamahi hei piripiri i roto i te paraikete, te gypsum, te paura putty, ētahi atu rauemi hanga rānei hei whakapai ake i te horapa me te whakaroa i te wā mahi; pērā i ngā taera uku, te māpere, te kirihou. Whakapaipai: Hei whakarei whakapiri, ka taea hoki e ia te whakaiti i te nui o te sima; mō te moata ārai-pakaru, tāpirihia he muka ārai-pakaru polypropylene (muka PP) ki te nui e tika ana, kia noho ai rātou i roto i te āhua o ngā tarau i roto i te moata, kia tutuki ai te pānga ārai-pakaru. Ko te mahi a te HPMC he pupuri wai, he whakamātotoru me te ārai-totoka.
1. Mota hangahanga mō te mota whakakī
Mā te pupuri wai nui ka tino makuku te sima, ka tino whakanui ake i te kaha o te here, ā, i te wa ano, ka taea te whakanui ake i te kaha kume me te kaha kutikuti, ka tino whakapai ake i te pānga hanga me te whakapai ake i te pai o te mahi.
2. Putty ātete-wai
I roto i te putty, ko te mahi nui a te hydroxypropyl methylcellulose cellulose ether ko te pupuri wai, te here me te whakahinuhinu, te karo i ngā kapiti me te maroke i puta mai i te nui o te ngaronga wai, ā, i te wa ano ka whakarei ake i te piri o te putty me te whakaiti i te totoro i te wā o te hanganga, kia maeneene ai te hanganga.
3. Raupapa pāreti pāreti
I roto i ngā hua raupapa gypsum, ko te hydroxypropyl methylcellulose cellulose ether te nuinga e pupuri ana i te wai me te whakahinuhinu, ā, i te wa ano he pānga whakaroa, e whakaoti ana i ngā raruraru o te pakaru o te pahu me te ngoikore o te kaha tuatahi i te wā hanga, ā, ka taea te whakawhānui ake i ngā hāora mahi.
4. Kaihoko atanga
Ko te nuinga o te wā ka whakamahia hei whakamātotoru, ka taea te whakapai ake i te kaha kume me te kaha kutikuti, te whakapai ake i te paninga mata, te whakarei ake i te piri me te kaha here.
5. Moata whakamahana pakitara o waho
I roto i tēnei rauemi, ko te mahi matua a te hydroxypropyl methylcellulose cellulose ether ko te hono me te whakanui ake i te kaha, kia māmā ake ai te paninga i te moata me te whakapai ake i te pai o te mahi. Ka whakanui ake i te wā mahi o te moata, ka whakapai ake i te ātete ki te whakaheke me te pakaru, ka whakapai ake i te kounga o te mata, ka whakanui ake i te kaha o te here.
6. Piripiri taera
Kāore e hiahiatia kia rumakina, kia whakamakuku rānei ngā taera me te turanga i mua i te pupuri wai, ka taea ai te whakapai ake i te kaha o te piri. Ka roa te wā hanga o te paru, he pai, he ōrite hoki, ā, he watea hoki mō te hanga. He pai hoki te ātete ki te makuku.
7, kaihoko whakapiri, kaihoko tohu
Te tāpiritanga ohydroxypropyl methylcellulose cellulose etherhe pai te here o te taha, he iti te mimiti me te ātete ki te kakahu, e tiaki ana i te rauemi turanga mai i ngā kino ā-mīhini, ā, e karo ana hoki i ngā kino i puta mai i te urunga ki te whare katoa.
