He aha te mahi matua o te whakamahinga o te hydroxypropyl methylcellulose ki roto i te paura putty, a he mea matū?
I roto i te paura putty, e toru nga mahi o te whakapakeke, te pupuri wai me te hanga. Ko te matotoru, ka taea e te cellulose te matotoru ki te whakatarewa, ka mau tonu te ahua o te otinga ki runga, ki raro, me te aukati i te paheketanga. Te pupuri wai: kia ata whakamaroke te paura putty, me te awhina i te konupūmā pungarehu ki te tauhohe i raro i te mahi a te wai. Hanganga: He whakahinuhinu te whakahinuhinu o te Cellulose, ka pai te hanga o te paura putty. Karekau a HPMC e uru ki nga tauhohenga matū, engari he mahi awhina noa.
Ko te Hydroxypropyl methylcellulose he ether cellulose kore-ionic, na he aha te mea-kore?
E ai ki nga korero a te reimana, karekau nga matū kore e uru ki nga tauhohenga matū.
Ko te CMC (carboxymethyl cellulose) he cellulose cationic, no reira ka huri hei pata pini ina tutaki ki te konupūmā pungarehu.
He aha te paanga o te reera o te hydroxypropyl methylcellulose e pa ana ki?
Ko te pāmahana reera o te HPMC e pa ana ki tana ihirangi methoxy, ko te iti iho o te ihirangi methoxy, ko te teitei ake o te pāmahana reera.
He hononga kei waenga i te maturuturunga iho o te paura putty me te hydroxypropyl methylcellulose?
He hononga! ! ! Ko te ngoikore o te pupuri wai o te HPMC, ka mate te paura.
He aha te rereketanga o te wai matao inamata me nga momo wairewa wera o te hydroxypropyl methylcellulose i roto i te tukanga whakaputa?
Ko te momo wai matao tonu o te HPMC he mea rongoa-mata ki te glyoxal, a ka marara tere ki te wai matao, engari kaore e tino memeha. Ka memeha noa ina piki te pokey. Ko nga momo whakarewa wera kaore i te rongoa ki te glyoxal. Mena he nui te nui o te glyoxal, ka tere te marara, engari ka piki haere te pokey, a mena he iti te nui, ka puta ke te ahua.
He aha te haunga o te hydroxypropyl methylcellulose?
Ko te HPMC i hangaia e te tikanga whakarewa ka whakamahi i te toluene me te isopropanol hei whakarewa. Mena kaore i te tino pai te horoinga, ka toe etahi kakara. (Ko te whakaora i te whakakorenga te tikanga matua o te kakara)
me pehea te whiriwhiri i te hydroxypropyl methylcellulose tika?
Putty paura: me nui te pupuri wai, he pai te hanga
Ko te kumete i runga i te sima noa: me nui te pupuri i te wai, te atete teitei o te pāmahana, me te pokey tonu (
Te whakamahi i te kapia hanga: nga hua inamata me te pokey teitei.
Moata gypsum: teitei te pupuri wai, te reo me te iti te pokey, te piki ake o te pokey
He aha te ingoa o te 16 hydroxypropyl methylcellulose?
E kiia ana ko te HPMC, ko te MHPC ingoa ingoa hypromellose, cellulose hydroxypropyl methyl ether.
Ko te whakamahinga o te hydroxypropyl methylcellulose ki te paura putty, he aha te take o nga mirumiru hau i roto i te paura putty?
I roto i te paura putty, e toru nga mahi a te HPMC mo te whakapakeke, te pupuri wai me te hanga. Ko nga take o nga mirumiru ko:
(1) He nui rawa te wai ka tapiritia.
(2) Ki te kore e maroke te papa o raro, waruhia tetahi atu paparanga ki runga, ka ngawari te pahuka.
He aha te rereketanga i waenga i te hydroxypropyl methylcellulose me te MC:
Ko te MC he methyl cellulose, he mea hanga mai i te cellulose ether ma te rongoa i te miro parakore ki te kawakore, te whakamahi i te methane chloride hei kaihoko etherification, me te whai i te raupapa tauhohenga. Ko te tikanga, ko te tohu whakakapinga he 1.6-2.0, he rereke te whakarewatanga ki nga nekehanga rereke o te whakakapi. He rereke, no te ether cellulose kore-ionic.
(1) Ko te pupuri wai o te methylcellulose e whakawhirinaki ana ki te nui o te taapiri, te pokey, te pai o te matūriki me te tere memeha. Ko te tikanga, mena he nui te taapiri, he iti te pai, he nui te pokey, he nui te reeti pupuri wai. I roto ia ratou, ko te nui o te taapiri he nui ake te paanga ki te reeti pupuri wai tangata. Kaore i te rite te pokey ki te tere pupuri wai. Ko te tere o te whakakorenga ka whakawhirinaki ki te mata o nga matūriki cellulose. Te tohu o te whakarereke me te pai o te matūriki. I roto i nga ethers cellulose i runga ake nei, ko te methyl cellulose me te hydroxypropyl methyl cellulose he teitei ake te reiti pupuri wai.
(2) He wairewa te Methylcellulose ki te wai matao, a ka uaua te memeha ki te wai wera. He tino pumau tona wairewa wai i te awhe ph=3-12. He pai te hototahi ki te māngaro, aha atu, me te maha o nga surfactants. Ka tae ki te pāmahana ka tae ki te mahana, ka puta te whakamahana.
(3) Ko nga huringa o te pāmahana ka tino pa ki te reiti pupuri wai o te methyl cellulose. Ko te tikanga, ko te teitei ake o te pāmahana, ko te kino te tere o te pupuri wai. Mena ka nui ake te pāmahana moata ki te 40 nga nekehanga, ka tino heke te pupuri wai o te methyl cellulose, ka tino pa ki te hanga o te moata.
(4) Ko te Methyl cellulose he painga nui ki te hanga me te whakapiri o te moata. Ko te whakapiri i konei e pa ana ki te kaha whakapiri i rongohia i waenga i te taputapu tono a te kaimahi me te taputapu pakitara, ara, te parenga kutikuti o te moata. He teitei te adhesiveness, he nui te parenga kutikuti o te moata, me te kaha e hiahiatia ana e nga kaimahi i roto i te tukanga o te whakamahinga he nui ano hoki, a, he kino te hanganga o te moata.
Kua wehea te Hydroxypropyl methylcellulose ki etahi momo, a he aha nga rereketanga o o raatau whakamahinga?
Ka taea te wehewehea te HPMC ki te momo inamata (te ingoa waitohu "S") me te momo wera-rewa. Ka tere te marara o nga momo momo hua i roto i te wai matao ka ngaro ki te wai. I tenei wa, karekau he pokarekare o te wai na te mea ka marara noa te HPMC ki te wai karekau he tino rewa. Mo te (kokorikori) mo te 2 meneti, ka piki haere te pokey o te wē, ka puta he colloid mā. Ko nga hua rewa wera, ka pa ki te wai matao, ka tere te marara i roto i te wai wera ka ngaro ki te wai wera. Ka heke te pāmahana ki tetahi pāmahana (e ai ki te pāmahana reera o te hua), ka ata puta te pokey tae noa ki te hanga i tetahi colloid puataata.
He aha nga tikanga whakakore o te hydroxypropyl methylcellulose?
1) Ka taea te taapiri i nga tauira katoa ki te rauemi ma te tikanga whakaranu maroke;
2) I te wa e tika ana kia taapiri atu ki te otinga wai mahana, he pai ake te whakamahi i te momo whakamararatanga wai matao, me te nuinga o te waa 10-90 meneti ki te matotoru i muri i te taapiri (whakaoho me te whakaoho)
3) Ko te tauira noa ka whakaohohia, ka marara ki te wai wera i te tuatahi, katahi ka taea te rewa i muri i te taapiri i te wai matao hei whakaoho me te whakamatao;
4) Mena ka puta te whakahiato me te takai i te wa e memeha ana, na te mea he iti te whakakorikori, he taapiri tika ranei te tauira noa ki te wai matao. I tenei wa, me tere te whakaoho. te
5) Mena ka puta nga mirumiru i te wa o te whakakorenga, ka waiho kia tu mo te 2-12 haora (ko te wa motuhake ka whakatauhia e te rite o te otinga) ka tangohia ranei ma te whakakore, te pehanga, me etahi atu, te nui ranei o te kaihoko whakakore. ka taea te taapiri. te
Me pehea te whakatau i te kounga o te hydroxypropyl methylcellulose ngawari me te ngawari?
1) Maama, ahakoa kaore e taea e te maaka te whakatau he ngawari te whakamahi a HPMC, a, ki te whakauruhia nga maaka ma ki roto i te mahinga whakaputa, ka pa ki tona kounga, engari ko te nuinga o nga hua pai he pai te ma.
2) Pai: Ko te pai o te HPMC he 80 te mata me te 100 te mata, he iti ake te 120 mata, he pai ake te pai ake.
3) Te tuku marama: I muri i te tuunga o te HPMC ki roto i te wai hei hanga i te colloid maramara, tirohia tona tukunga marama. Ko te nui ake o te whakawhiti marama, ka pai ake, e tohu ana he iti ake nga koretake o roto, a he pai te tuku o nga reactor poutū. , He kino ake te reactor whakapae, engari ehara i te mea ko te kounga o te reactor poutū he pai ake i tera o te reactor whakapae, a he maha nga mea hei whakatau i te kounga o te hua.
4) Te taumahatanga motuhake: Ko te nui ake o te taumahatanga motuhake, ko te taumaha ka pai ake. Ko te teitei ake o te taumaha motuhake, ka nui ake te ihirangi hydroxypropyl i roto i te hua. Ko te teitei o te ihirangi hydroxypropyl, ko te pai ake o te pupuri wai.
