Ko te hydroxypropyl methylcellulose ether inamata kua hangaia mo nga hua-wai. Ko te mata o te hydroxypropyl methylcellulose ether ka tukuna ki te glyoxal i raro i tetahi pāmahana me te uara pH. Ko te hydroxypropyl methyl cellulose ether i mahia penei ka marara noa ki roto i te wai matao kore kore e pupuhi me te pokey, e whai waahi ana ki te whakaroa i te pupuhi. I tenei wa, ka whakaohohia te wairewa wai mo te 5-10 meneti ranei i te wa ka whakatikahia te taiao otinga (te uara PH) ki te kawakore, ka timata te hydroxypropyl methylcellulose ether ki te pupuhi me te whakaputa i te viscosity. Ko tenei momo mahi-mata ka kiia he momo inamata.
Ko te ahuatanga o te hydroxypropyl methylcellulose inamata ko te wa ka tutaki ki te wai matao, ka tere te rere ki roto i te wai matao, engari ka roa te wa e piki ai tona poiketanga, na te mea ka marara noa ki roto i te wai i te timatanga, karekau e memeha i roto i te tikanga nui. Ka tae tona pokey ki te uara teitei mo te 20 meneti neke atu ranei. Ko te painga o tenei ka whakamahia i roto i te ahumahi motuhake kaore he whakamaroke paura maroke, i te wa e hiahia ana ki te whakakore me te kore e taea te whakamahi i te wai wera mo nga tikanga taputapu me etahi atu take. Ko te hydroxypropyl methylcellulose inamata ka whakaoti i taua raruraru.
Ko te hydroxypropyl methylcellulose te momo inamata ka marara ki roto i te wai (ko te tohu whakamararatanga he 100%), he tere te rewa, kaore e kopiri, ina koa i te wa o muri mai, he tino marama te otinga colloidal (tae atu ki te 95%) me te riterite nui, e whakaoti rapanga i roto i nga tono mahi. Nga herenga, te whakawhänui i te waahi tono, penei i te tono i roto i te kapia hanga, te tono i roto i nga whakauru wai whakahiato, me nga waahi motuhake penei i te horoi matū o ia ra.
Kua whakaurua e matou nga taputapu whakangao me te hangarau o te ao, he raina hanga hou o te cellulose ether me te paura taherapa redispersible, me te whakarite ki te whakarato ki nga kaiwhakamahi nga hua pai me tana punaha whakahaere kounga tino, punaha whakamatautau me te tino ratonga i runga i te waahi. Inaianei ko nga hua matua ko te hydroxypropyl methylcellulose HPMC, hydroxyethyl cellulose HEC, hydroxypropyl starch ether HPS, raupapa paura taherapa tukurua. Ko nga hua e whakamahia nuitia ana i roto i te hangahanga, te ahumahi matū, te peita, te ahumahi matū o ia ra, te ahumahi hoia me etahi atu mara, a ka hangaia hei kaihanga kiriata, whakapiri, dispersants, stabilizers, thickeners, etc.
Te ti'aturi i runga i tona ake kounga hua me tona mana me te awe i roto i te hanga paura maroke ahumahi tāpiritanga rauemi, a i raro i te kaupapa o te mau tonu te misioni rangatōpū o te kounga tuatahi, kei te mahi tahi te reira ki te ao, me te kāinga pai-mohiotia kaihanga mō hua tāpiritanga. Te tautoko i nga mahi: te muka polypropylene, te muka rakau, te ether starch kua whakarereketia, te paura waipiro polyvinyl, te paura paura, te whakaheke wai, te aukati wai, te whakatakotoranga konupūmā me etahi atu taapiri paura maroke.
