FAQ
HPMC raneiHydroxypropyl methylcellulose(ingoa INN: Hypromellose), he mea ngawari ano hei hydroxypropyl methylcellulose (HPMC), he momo o te cellulose kore-ionic i konatunatua ether. He waerau hangarua, hohekore, viscoelastic. Ko te Hydroxypropyl methylcellulose e whakamahia nuitia ana i roto i te hanga, te kai, te rongoa, me etahi atu ahumahi.
HPMC CAS Nama: 9004-65-3
Hanganga HPMC:
HPMC HS Waehere: 3912390000
Āhuatanga matū:
Te ahua: He paura ma, he rite ranei te ahua.
Rahi matūriki; Ko te 100 mesh reeti neke atu i te 98.5%; Ko te 80 te reeti whakawhiti mata he 100%. Ko nga rahi matūriki o nga whakaritenga motuhake mai i te 40 ki te 60 mata.
Kiato tirohanga: 0.25-0.70g/cm (te nuinga o te 0.5g/cm), te taumaha motuhake 1.26-1.31.
Wairewa: Ka whakarewahia i roto i te wai me etahi whakarewa, penei i te wahanga tika o te waiwaro/wai, propanol/wai, aha atu. He mahi mata te wairewa wai. Ma te maamaatanga teitei me te mahi pumau, he rereke te wera o te reera o nga whakaritenga rereke, he rereke te rerekee me te viscosity, he iti ake te pokey me te nui ake o te whakarewatanga. Ko te mahinga o te HPMC me nga korero rereke he rereke rereke. Ko te whakakorenga o te HPMC i roto i te wai kaore e pa ki te uara PH.

Ko te Hydroxypropyl methylcellulose (HPMC) he etera cellulose kua whai roopu hydroxyl i runga i te mekameka cellulose kua whakakapi mo te roopu methoxy, hydroxypropyl ranei.It he mea hanga ma te whakaea motuhake o te miro cellulose tino parakore i raro i nga tikanga kawakore. I nga tau tata nei, ko te HPMC, hei whakaurunga mahi, te nuinga o te mahisi roto i te pupuri wai me te thickening i roto i te ahumahi hanga me te whakamahia whānuitia i roto imota whakamaroke, penei i te whakapiri taera, te kumara, te raima, te putty pakitara, te whakamaarama whaiaro, te kumete whakamaarama me etahi atu.
Ko te tikanga, mo te paura putty, te pokey oHPMChe nui kei te 70,000 ki te 80,000. Ko te kaupapa matua ko tana mahi pupuri wai, engari he iti noa iho te hua o te whakapakeke. Mo te kumete, nga whakaritenga moHPMChe teitei ake, a me tata ki te 150,000 te viscosity, ka pai ake te mahi i roto i te kumete ciment. Ko te tikanga, i roto i te paura putty, i te mea he pai te mahi pupuri wai o HPMC, ahakoa he iti te viscosity (70,000 ki te 80,000), ka whakaaetia. Engari, i roto i te moata ciment, he pai ake te whiriwhiri i te HPMC me te nui ake o te viscosity (neke atu i te 100,000), no te mea he nui ake te painga o te pupuri wai i tenei ahuatanga.
Ko te raruraru o te tango paura putty te nuinga ka whakawhirinaki ki te kounga o te konupūmā waihā me te iti o te mahi ki te HPMC. Mena he iti te ihirangi konupūmā o te konupūmā waihā, he hē rānei te ōwehenga o CaO me Ca(OH)2, ka taka pea te paura putty. Mo te paanga o te HPMC, ka kitea i roto i tana mahi pupuri wai. Mena he ngoikore te mahi pupuri wai o te HPMC, ka whai paanga ano ki te whakakore i te paura putty.
He iti noa nga whakaritenga mo te whakamahi i te paura putty. Ko te pokey o te 100,000 ka nui. Ko te mea nui kia pai te pupuri i te wai. I runga i nga tikanga mo te moata, he ahua teitei nga whakaritenga me te nui ake o te viscosity e hiahiatia ana, a he pai ake te painga o te hua 150,000.
(1) Ahumahi hanga: Hei kaihoko pupuri wai me te aukati o te kumete ciment, ka taea e te moata te pupuhi. Whakamahia te raima, te gypsum, te paura putty me etahi atu mea hanga whare hei whakapiringa hei whakapai ake i te whaihua me te whakaroa i te wa mahi. Ka taea te whakamahi ki te whakapiri i te tile ceramic, te mapere, te whakapaipai kirihou, te whakapiri i te kaihoko whakakaha, me te whakaiti i te nui o te ciment. Ko te taonga pupuri wai o te HPMC ka aukati i te parapara kia pakaru na te tere rawa o te whakamaroke i muri i te paninga me te whakanui ake i te kaha.
(2) Ahumahi hanga uku: whakamahia nuitia hei whakapiri i roto i te hanga o nga hua uku.h i muri i te whakapakeke.
(3) Ahumahi whakakikorua: Ka rite ki te whakamaarama, te dispersant me te whakapumau i roto i te ahumahi whakakikorua, he pai te whakarewatanga i roto i te wai, i nga whakarewa pararopi ranei.
(4) Ink tā: Hei whakakaha, dispersant me te stabilizer i roto i te ahumahi mangumangu, he pai te wairewa i roto i te wai whakarewa organic ranei.
(5) Plastics: rite hanga kaihoko tuku, ngohengohe, whakahinuhinu, etc.
(6) Polyvinyl chloride: Ka rite ki te dispersant i roto i te hanga o te polyvinyl chloride, ko ia te kaiawhina matua i roto i te whakarite o te PVC na roto i te polymerization whakatārewatanga.
(7) Ētahi atu: Kei te whakamahia whānuitia tenei hua i roto i te hiako, hua pepa, hua me te tiaki huawhenua, me te ahumahi pueru.
