WAEHERE HS HPMC: 3912390000
Āhuatanga matū:
Āhua: He paura mā, he paura rite rānei.
Rahi matūriki; neke atu i te 98.5% te tere paahi 100 mata; 100% te tere paahi 80 mata. Ko ngā rahi matūriki o ngā whakaritenga motuhake i waenga i te 40 ki te 60 mata.
Kiato tirohanga: 0.25-0.70g/cm (tata ki te 0.5g/cm), taumaha motuhake 1.26-1.31.

Ko te Hydroxypropyl methylcellulose (HPMC) he cellulose ethers kua whakakapia ō rātou rōpū hydroxyl ki te rōpū methoxy, hydroxypropyl rānei i runga i te mekameka cellulose.It i hangaia mā te whakaetere motuhake o te cellulose miro tino parakore i raro i ngā āhuatanga kawakore. I ngā tau tata nei, ko te HPMC, hei ranunga mahi, te mea nui e whai wāhi anasi roto i te pupuri wai me te whakamātotoru i roto i te umanga hanga, ā, e whakamahia whānuitia ana i roto ingā mota whakaranu maroke, pērā i te piripiri taera, te grout, te parakimete, te putty pakitara, te whakataurite-ake, te mota whakamahana me ētahi atu.
I te nuinga o te wā, mō te paura putty, ko te matotoru oHPMChe rawaka i te 70,000 ki te 80,000 pea. Ko te arotahi matua ko tōna mahi pupuri wai, engari he iti noa te pānga whakamātotoru. Mō te moata, ko ngā whakaritenga mōHPMChe teitei ake, ā, me tata ki te 150,000 te matotoru, ka taea ai te whakarite kia pai ake te mahi i roto i te moata sima. Ae, i roto i te paura putty, mena he pai te mahi pupuri wai o te HPMC, ahakoa he iti te matotoru (70,000 ki te 80,000), he pai ake. Heoi, i roto i te moata sima, he pai ake te whiriwhiri i te HPMC me te matotoru nui ake (neke atu i te 100,000), nā te mea he nui ake te pānga pupuri wai i roto i tēnei āhuatanga.
Ko te raruraru o te tango i te paura putty e whakawhirinaki ana ki te kounga o te konupūmā hauwai, ā, kāore he pānga ki te HPMC. Mena he iti te ihirangi konupūmā o te konupūmā hauwai, he kore rānei te ōwehenga o te CaO me te Ca(OH)2 e tika ana, ka taka pea te paura putty. Mō te pānga o te HPMC, ko te nuinga o te wā ka kitea i roto i tana mahi pupuri wai. Mena he ngoikore te mahi pupuri wai o te HPMC, tera pea ka pā ki te tango paura o te paura putty.
He iti noa ngā whakaritenga mō te whakamahi i te paura putty. He nui te matotoru o te 100,000. Ko te mea nui kia pai te pupuri i te wai. Mō te moata, he teitei ake ngā whakaritenga, ā, me nui ake te matotoru, ā, he pai ake te hua o te 150,000.
(1) Ahumahi hanga: Hei mea pupuri wai, hei mea whakaroa hoki i te moata sima, ka taea te papu i te moata. Whakamahia te paraikete, te gypsum, te paura putty, ētahi atu rauemi hanga rānei hei piripiri hei whakapai ake i te whakamahinga me te roa ake o te wā mahi. Ka taea te whakamahi hei whakapiri i ngā taera uku, te māpere, te whakapaipai kirihou, te kaihoko whakapakari whakapiri, me te whakaiti i te nui o te sima. Ko te āhuatanga pupuri wai o te HPMC ka ārai i te pakaru o te paru nā te tere rawa o te maroke i muri i te paninga, ā, ka whakanui ake i te kaha.
(2) Te umanga hanga uku: e whakamahia whānuitia ana hei piripiri i roto i te hanga hua uku i muri i te whakapakeketanga.
(3) Te umanga paninga: Hei whakamātotoru, hei whakamarara me hei whakau i roto i te umanga paninga, he pai te wairewatanga ki te wai, ki ngā whakarewa waro rānei.
(4) Tānga waituhi: Hei whakamātotoru, hei whakamarara me hei whakau i roto i te umanga waituhi, he pai te wairewatanga ki te wai, ki ngā whakarewa rauropi rānei.
(5) Kirihou: hei kaihanga tuku, hei whakangawari, hei hinu whakahinuhinu, me ētahi atu.
(6) Polyvinyl chloride: Hei mea whakamarara i roto i te hanga o te polyvinyl chloride, koia te kaiawhina matua i roto i te whakarite o te PVC mā te whakapūhui whakatārewatanga.
(7) Ētahi atu: E whakamahia whānuitia ana hoki tēnei hua i roto i te hiako, ngā hua pepa, te tiaki hua me te huawhenua, me te ahumahi kakahu.
