Hydroxypropyl Methyl Cellulose
Ko te Hydroxypropyl methyl cellulose ko te eone cellulose nonionic e hua mai ana i te raima parakore ma te raupapa o nga mahi eterification. Ko tana mahi nui ko enei e whai ake nei:
1. He paura ma, he kowhai kowhai ranei te HPMC. kakara, kore-paitini
2. Ka taea te rewa o HPMC i roto i te wai makariri ki te hanga i tetahi otinga panui ngawari; Na te mea kei te nui o te roopu methoxy hydrophobic, ka taea te rewa i etahi whakarewa noaa
3. Ko te pokarekare o te otinga wai HPMC he pumau i roto i te whānuitanga o te PH3.0-10.0. Mena he iti iho te uara PH i te 3 neke atu ranei i te 10, ka tino whakaitihia te pokey
4. Ko te rongoa wai o te HPMC he mahinga o te mata, na reira ka whakaitihia e ia te aukati i te noho whanaunga o te koroi.
5. Ko te whakamahinga o te horoi wai wera me te aata whakamahine i te waa whakariterite i iti ai te pungarehu
6. Ko te HPMC he hydrophilic, tapiritia ki te kumete, gypsum, peita me etahi atu hua hei whai waahi pupuri wai nui
7. He pai te tohetohe o te HPMC me te piripono pai i roto i te rokiroki mo nga wa roa
8. Ka taea e HPMC te whakaheke i te ngoikoretanga paraikete me te whakapai ake i te hinu o te hanga
9. Ka taea e te HPMC te whakaputa i tetahi pepa maarama ngawari me te ngawari me te hinu pai me te aukume ester

Tono:
1. Te peihana o roto me waho
Ko te pupuri i te wai o te HPMC kaore e pakaru te paura putty no te mea he tere rawa te maroke i muri o te hanganga, he whakarei ake i te kaha i muri i te whakapakeke.
2. Punaha miihini taiepa o waho
Ma te taapiri o te HPMC ka taea te whakapai ake i te kaha o te hononga me te maeneene o te moata, kia pai ake ai te mahi
3. Tuutui whakaranu
Ko te pupuri pai i te wai HPMC, ka roa ake te waa hangahanga, aukati i te taera uku kia ngaro te wai kia tere te arahi ki te taka atu, te whakapai ake i te kaha o te hononga me te kaha kutikuti.
4. Gypsum turanga raima me nga hua
Ko te ātete ki te whakairi i te HPMC ka taea te whakakore i te riihi o te whare ka tono i te paninga matotoru
5. Te raima whakarewa Miihini
Ka taea e te HPMC te whakapai ake i te maatatanga o te moata, whakahaere i te whakawhiti papu, aukati i te whakakotahitanga o te moata me te tapahi paipa
6. Whakapapa parakae (papa hangarua)
Ka taea e te HPMC te whakapai ake i te rawa piripiri o te pepa gypsum i muri i te tangohanga, te whakapai ake i te kaha o te hononga me te whakahinuhinu, me te whakarite kia kaha te kaha
7. Te miihini whakaheke-totika
He kaha te HPMC pokekore ki te aukati i te rerenga rerehua me te whakarei i te rere o te moata. Ko te pupuri o te wai e aukati ana i te pakaru me te heke.
Te Tauhokohoko / Tauhokohoko
Ko nga hua kei te whakairihia i roto i nga peke tuukino polypropylene me nga peke polythene o roto, i pania ki te kirihou, me te taumaha i te 25kg mo ia bag.Ki aro ki te ua me te tiaki ra i te wa e whakawhiti ana.
