HPMC LK500 mo te moata Whakataumata Whaiaro
Whakaahuatanga Hua
Hydroxypropyl MethylEtera CelluloseKo te LK500 he taapiri mo nga moata e hiahiatia anawē teitei. Ko tana mahi matua ko te whakanui ake i tanapupuri waite kaha me te kaha whakatārewatanga i roto i te kumete me te iti o te paanga ki te rere.

☑ Te ora papa
E rua tau te wa whakamana. Whakamahia i te wa e taea ai i raro i te teitei o te pāmahana me te haumākū, kia kore ai e piki ake te tupono o te caking.
☑ Te haumaru hua
Ko te Hydroxypropyl methyl cellulose HPMC LK10M ehara i te taonga morearea. Ko etahi atu korero mo nga waahanga haumaru ka tukuna i te Rau Raraunga Haumaru Rawa.
FAQ
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.
