3. He hononga kei waenga i te maturuturunga iho o te paura putty me te HPMC?

Ko te paura paura o te paura putty te nuinga e pa ana ki te kounga o te konupūmā pungarehu, me te iti o te mahi ki te HPMC.Ko te ihirangi konupūmā o te konupūmā hina me te ōwehenga o CaO me Ca(OH)2 i roto i te konupūmā hina e kore e pai, ka mate te paura.Mēnā he pā ana ki te HPMC, nā te ngoikore o te pupuri i te wai o te HPMC ka ngaro te paura.

4. He aha te nui o te hydroxypropyl methylcellulose (HPMC) i roto i te paura putty?

Ko te nui o te HPMC e whakamahia ana i roto i nga mahi mahi he rereke i runga i te ahuarangi, te mahana, te kounga o te konupūmā pungarehu o te rohe, te tauira o te paura putty me te 'kounga e hiahiatia ana e nga kaihoko'.

6. Me pehea te whiriwhiri i te hydroxypropyl methylcellulose (HPMC) e tika ana mo nga kaupapa rereke?

Te tono o te paura putty: he iti nga whakaritenga, he 100,000 te viscosity, he nui, ko te mea nui kia pai te pupuri i te wai.Te tono moata: nga whakaritenga teitei, te nui o te pokey, te 150,000 he pai ake, te tono kapia: e hiahiatia ana nga hua inamata, te nui o te pokey.

7. Ko te tono o te HPMC ki te paura putty, he aha te take mo nga mirumiru i roto i te paura putty?

1. Kia nui rawa te wai.

2. Ki te kore e maroke te paparanga o raro, ka waruhia tetahi atu paparanga ki runga, ka ngawari te pahuka.
