Whakatakotoranga
Te ahua:he ma, he ma-ma ranei te paura kirikiri, kirikiri ranei
Pūmautanga:Ko te totoka he mura me te kore hototahi ki nga waikura kaha.
Rahi matūriki:Ko te 100 mesh reeti haere he nui ake i te 98.5%;Ko te 80 te reeti whakawhiti mata he 100%.Ko te rahi matūriki o nga whakaritenga motuhake ko te 40-60 mata.
Te pāmahana waro:280-300 ℃
Kiato ahua:0.25-0.70g/cm3 (te nuinga o te 0.5g/cm3), te taumaha motuhake 1.26-1.31.
Te wera o te tae:190-200 ℃
Te mānukanuka mata:Ko te 2% wairewa wai he 42-56dyne/cm
Wairewa:wairewa ki te wai me etahi whakarewa, penei i te wahanga tika o te waiwaro/wai, propanol/wai, me etahi atu.He maamaa teitei me te mahi pumau.He rereke nga ahuatanga o nga hua ka rereke te mahana o te reera, me te rereke o te wairewa ki te pokey.Ko te iti o te pokey, ka nui ake te whakarewatanga.Ko nga korero rereke o te HPMC he rereke nga mahi.Ko te whakakorenga o te HPMC i roto i te wai kaore e pa ki te uara pH.
Whakamahi
1. Ahumahi hanga:Hei kaikawe pupuri wai me te aukati mo te kumete ciment, ka taea e te moata te pupuhi.Ka whakamahia hei here mo te whakapiri raima, te gypsum, te paura putty me etahi atu mea hanga whare hei whakapai ake i te horahanga me te whakaroa i te waa mahi.Ka whakamahia hei whakapiri mo te tira karaima, te mapere, te whakapaipai kirihou, hei whakanui i te whakapiri, ka taea hoki te whakaiti i te nui o te ciment.Ko te pupuri wai o te HPMC ka taea te aukati i te slurry mai i te pakaru na te mea he tere rawa te whakamaroke i muri i te tono, me te whakarei ake i te kaha i muri i te whakapakeke.
2. Te hanga uku:whakamahia whānuitia hei here i roto i te hanga hua uku.
3. Ahumahi whakakikorua:Ka rite ki te thickener, dispersant me te pūmau i roto i te ahumahi paninga, he pai hototahi i roto i te wai whakarewa organic ranei.hei tango peita.
4. Tā waituhi:hei whakakaha, whakamarara me te whakapumau i roto i te umanga waituhi, he pai te hototahi ki roto i te wai, i nga whakarewa pararopi ranei.
5. Kirihou:whakamahia hei kaihoko tuku whakarewa, whakangawari, whakahinuhinu, aha atu.
6. Polyvinyl chloride:Kei te whakamahia hei dispersant i roto i te hanga o te polyvinyl chloride, a ko ia te kaihoko awhina matua mo te whakarite o te PVC ma te polymerization whakatārewatanga.
7. Ahumahi rongoā:rauemi whakakikorua;rauemi kiriata;nga rauemi polymer reiti-whakahaere mo nga whakaritenga tuku-mau;whakapūmau;nga kaihoko whakatārewa;nga here papa;nga tackifiers
8. Ētahi atu:Kei te whakamahia nuitia i roto i te hiako, ahumahi hua pepa, hua me te tiaki huawhenua me te ahumahi pueru.
