Whakaahuatanga Hua:
Ko te Hydroxypropyl Methylcellulose (HPMC) he paura maamaa kore-paitini. I muri i te tino rewa i roto i te wai, ka hanga i te otinga viscous marama. He ether cellulose kore-ionic i hangaia mai i nga rauemi polymer taiao na roto i te raupapa o te tukatuka matū. Kei a ia nga ahuatanga o te matotoru, te adhesion, te marara, te emulsification, te hanga kiriata, te whakatārewatanga, te adsorption, te gelation, te mahi mata, te pupuri i te makuku me te tiaki i nga colloids.
Taupānga:
Te wairewa wai me te kaha matotoru: ka taea te rewa i roto i te wai matao, me te hanga i te wairewa viscous marama.
Te whakakorenga i roto i nga whakarewa pararopi: Na te mea he maha nga roopu methoxy hydrophobic kei roto, ka taea te rewa tenei hua ki etahi whakarewa pararopi.
Pumautanga uara PH: Ko te pokey o te wairewa wai a HPMC he tino pumau i roto i te awhe o te uara PH 3.0-11.0.
Mahi mata: He mahi mata te wairewa wai HPMC. He pānga whakaemulsifying, tiaki colloid kaha me te pūmautanga whanaunga.
Te waiariki waiariki: Ka wera i runga ake i tetahi pāmahana, ko te otinga wai o te HPMC ka puataata, ka whakaputa i te rerenga, ka ngaro te pokey. Heoi, ka huri haere ki te ahua otinga taketake i muri i te whakamatao.
Te iti o te pungarehu: Ko te HPMC he kore-katote, ka taea te horoi ki te wai wera i te wa o te whakaritenga me te parakore pai, na reira he iti rawa te kiko o te pungarehu.
Te ātete ki te tote: I te mea ko tenei hua he electrolyte kore-katote me te polymeric kore, he ahua pumau i roto i nga wairewa wai o nga tote whakarewa me nga electrolytes waro.
Te painga o te pupuri wai: Na te mea he hauwai te HPMC me tana wairewa wai he tino poiketa. Ka taea te taapiri ki te kumete, ki te gypsum, ki te peita, me etahi atu hei pupuri i te pupuri wai nui i roto i te hua.
Te ātete ki te koriri: He ahua pai te atete ki te koriri, he pai te whakapumautanga i te wa roa o te rokiroki.
Te whakahinuhinu: Ko te taapiri HPMC ka taea te whakaiti i te whakarea waku me te whakapai ake i te whakahinuhinu o nga hua uku me nga hua ciment.
Nga taonga hanga kiriata: Ka taea e ia te whakaputa i nga tawerewere kaha, ngawari, maamaa me te hinu pai me te aukati ester.
I roto i nga taonga hanga, ka taea te whakamahi i te cellulose HPMC hei kaihoko pupuri wai me te aukati mo te slurry ciment kia pai ai te moata.
Hei whakapiri, ma te whakamahi i te HPMC i roto i te raima, te gypsum, te paura putty me etahi atu mea hanga whare ka taea te whakapai ake i te horahanga me te whakaroa i te waa mahi.
Ka taea e tana pupuri wai te aukati i te whakapiri kia tere rawa te pakaru i muri i te paninga, ka taea hoki te whakarei ake i te kaha o te paninga i muri i te whakapakeke.
I tua atu, ka taea hoki te whakamahi matū HPMC hei whakarei adhesion mo te taera, mapere, me te whakapaipai kirihou i roto i te ahumahi hanga.
I tua atu, ka whakamahia te paura HPMC hei whakamaroke, whakapumau, emulsifier, excipient, me te kaihoko pupuri wai i roto i te hanga o etahi atu ahumahi, penei i te petrochemicals, paninga, rauemi hanga, tango peita, matū ahuwhenua, waituhi, tuhinga kakano me te tae, uku, hanga pepa, whakapaipai, etc.
Mōkī: 25 kgs / peeke ranei rite tono koe.
Rokiroki: Rokiroki ki te waahi hau, maroke.
Paerewa i mahia: Paerewa Ao.
