HPMC e whakamahia ana i roto i te Putty Pakitara/Papa ​​Kirikiri

He maha ngā mahi a te HPMC, arā, te Hydroxypropyl Methyl Cellulose, i runga i tōna kounga. I Haina, e whakamahia nuitia ana i roto i te hanga whare. Ina koa, i roto i te hanga o te putty pakitara, te paninga kiri rānei, ka whakaranua kia tino pai te nui o te paura paninga kiri, tae atu ki te HPMC me ētahi atu rauemi paura, kātahi ka whakarewahia mā te tāpiri wai. Mā tēnei tikanga ka ārai i te kohikohinga nā te memeha tonu o ngā matūriki HPMC ki roto i te wai.

Ko te pāmahana tiēre o te HPMC e whakawhirinaki ana ki te nui o te methoxy; ko te iti o te nui o te methoxy ka hua ake he pāmahana tiēre teitei ake. Ko te HPMC wairewa-inamata i te wai matao, i rongoatia ki te glyoxal, ka tere te marara i roto i te wai matao, ka whakaatu i te matotoru nui ake engari kāore i te tino memeha. I tetahi atu taha, ko te HPMC wairewa-mahana, i rongoatia ki te glyoxal, ka tere te marara engari he puhoi ake te matotoru me te iti o te nui. Ka taea te whakarōpū i te HPMC ki ngā momo inamata me te wairewa-wera. Ka tere te marara o ngā hua inamata i roto i te wai matao ka piki haere te matotoru, ka hanga he colloid matotoru mārama. Ko ngā momo wairewa-wera, e tika ana mō te paninga kiri me te moata, ka whakaatu i te kohikohinga i roto i te kāpia wai me te paninga.

Ko te hanga o te HPMC he tikanga whakarewa e whakamahi ana i te toluene, i te waipiro isopropyl rānei. Ko te whakamahinga o te paura paninga kiri iti me iti ake te matotoru, tata ki te 10,000, me te arotahi ki te tiaki wai. Ko te whakamahinga o te moata me nui ake te matotoru, tata ki te 15,000, ko te whakamahinga o te kāpia me tere tonu te whakamahi i ngā hua matotoru teitei. Ko te nui o te HPMC e whakamahia ana ka rerekē i runga i te āhuarangi, te pāmahana taiao, te kounga o te konupūmā hina o te rohe, te tauira paninga kiri iti, me ngā whakaritenga kounga a te kiritaki.

Ko te HPMC, he matotoru te paura paninga kiri o te 100,000, he mea nui ki te pupuri me te whakamātotoru i te wai. Heoi, i roto i ngā mahi whaihua, he pai te matotoru o te 70,000 ki te 80,000. Ko te mahi matua a te HPMC i roto i te paninga kiri ko te whakamātotoru, te pupuri wai, me te āwhina i te hanganga. Kāore e whai wāhi ki ngā tauhohenga matū engari ka whai wāhi ki te aukati i te hanganga mirumiru mā te whakarite kia maroke tika.

He mea nui te whanaungatanga i waenga i te paura paninga pakitara/paninga kiriuhi me te kounga konupūmā pungarehu matua, engari he iti noa te awe o te HPMC. Ka pā te mahi a te HPMC ki te pupuri wai ki te totohu o te paura, ā, ko tana taunekeneke ki te wai i te wā e pania ana te paninga kiriuhi he tauhohenga matū, ka hanga he matū hou (konupūmā kāponāte). Heoi, kāore te HPMC e whai wāhi ki ēnei tauhohenga.

He maha ngā momo paura putty pakitara e whakatutuki ana i ngā hiahia rerekē, pērā i te putty pakitara o roto noa, te putty pakitara o roto pakeke rawa, te putty pakitara o roto ātete-wai, te putty pakitara o waho pakeke rawa, te putty pakitara o roto ka taea te horoi me te ātete-haehae, me te putty ārai-ngatata pakitara o waho ka taea te horoi, me ētahi atu. E tohu ana ia tauira i te ōrau o te Paura Polymer Whakamarara Anō (RDP), te paura rere rua, te paura konupūmā hina, te sima mā, me te HPMC, i hangaia mō ngā tono motuhake pērā i te moata, te kāpia, te paninga rānei.
