Nā te mea kua nui haere ngā mākete mō te hydroxypropyl carboxymethyl cellulose, ā, kāore i te ōrite ngā utu, kua noho ko te huarahi ngāwari me te tere ki te whakatau i te kounga o te hydroxypropyl carboxymethyl cellulose hei take nui! Nā, me pēhea te aromatawai i te kounga o te hydroxypropyl methylcellulose? Ko te mea tuatahi hei tirotiro ko te mā o te hydroxypropyl cellulose; ahakoa kāore e taea e te mā te whakatau mēnā he pai te HPMC mō te whakamahi, ka tāpirihia e ētahi kaihanga nanakia he kaihoko mā i te wā e tukatuka ana, ka pā ki tōna kounga. Engari i te nuinga o te wā, he pai ake te mā o te nuinga o ngā cellulose ethers pai rawa atu.
Tuarua, e whakawhirinaki ana ki te pai o te hydroxypropyl methylcellulose: ko te rahi o te matūriki o te hydroxypropyl carboxymethyl cellulose he 80-100 mata, iti iho i te 120 mata, ā, ko te hydroxyethyl cellulose HECHPMC he tata ki te 100 mata. Ko te nuinga o te hpmc he 60-80 mata. I te nuinga o te wā, ko te ngawari o te methyl cellulose, ko te pai ake o te marara.
Te māramatanga o te cellulose ether i roto i te otinga: tāpirihia te HPMC ki roto i te wai hei whakaputa i te otinga colloidal mārama, ko te teitei ake o te māramatanga, ko te teitei ake o te māramatanga, ko te iti iho o ngā matū kore e rewa.
Ina whakamahanahia te taonga, ka whakapūpū, ka rewa rānei. He wai-kore, he wairewa hoki. Ko te raima te rauemi matua mō te hono me te tango i ngā matūriki mō te paura putty ātete-wai. Ko te kaupapa o te ātete-wai penei: ina konatunatua te paura rapa me te sima ki te wai, ka hoki tonu te paura rapa ki te āhua taketake, ā, ka horapa ōrite ngā matūriki rapa ki roto i te paru sima. I muri i te tūtakitanga o te sima ki te wai, ka tīmata te tauhohenga wai, ā, ka tae te otinga Ca(OH)2 ki te mātotoru, ka puta ngā tioata. I taua wā anō, ka hangaia ngā tioata ettringite me ngā colloids hydrate konupūmā silicate, ā, ka whakatakotoria ngā matūriki rapa ki runga i te tire me ngā matūriki sima kāore i wai. I te haere tonu o te tauhohenga wai, ka piki haere tonu ngā hua wai, ā, ka huihui haere ngā matūriki rapa ki roto i ngā āputa o ngā rauemi kore-waro pērā i te sima, ā, ka hanga he paparanga kapi ki runga i te mata o te tire sima. , nā te hekenga haere o te makuku maroke, ka whiri ngā matūriki rapa kua marara tata anō i roto i te tiēre me ngā āputa hei hanga i tētahi kiriata tonu, ka hanga he ranunga me te anga uru o te whakapiri sima, ā, ka hangaia te whakapiri sima me ētahi atu paura. Ka piri ngā mea whakahiato tetahi ki tetahi.
