☑ Te rokiroki me te tuku
Me rongoa, me tuku hoki i roto i ngā āhuatanga maroke, ma, i roto i tōna āhua taketake, kia matara atu hoki i te wera. I muri i te whakatuwheratanga o te kete mō te hanga, me hiri anō kia piri kia kore ai e uru te makuku.
Mōkihi: 25kg/pēke, pēke pepa kirihou maha-apa me te whakatuwheratanga takirere raro tapawhā, me te pēke kiriata polyethylene paparanga o roto.
☑ Te roa o te oranga
E rua tau te roa o te wā whakamana. Whakamahia i te wā e taea ai i raro i te pāmahana me te haumākū tiketike, kia kore ai e piki ake te tūponotanga o te pirau.
☑ Te haumaru o te hua
Kāore te Hydroxypropyl methyl cellulose HPMC LK10M i roto i te rauemi morearea. Kei roto i te Rauemi Raraunga Haumaru Rauemi ētahi atu kōrero mō ngā āhuatanga haumaru.
Ngā Pātai Auau
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.
