Ko te HPMC Hydroxypropyl methyl cellulose, e mohiotia ana ko te hydroxypropyl methyl cellulose ether (HPMC), te cellulose hydroxypropyl methyl ether, ko te kowhiringa o te cellulose miro tino parakore hei rauemi mata, i raro i nga tikanga kawakore ma te etherification motuhake me te whakarite.
Hydroxypropyl methyl cellulose HPMC whakamahia i roto i te hanga, cellulose etera tāpiri nui he tino iti, engari ka taea e tino whakapai ake i te mahi o te kumete mākū, mahi moata hanga ko te tāpiritanga nui.Na, hydroxypropyl methyl cellulose whakamahia i roto i te kumete maroke cellulose ether ko te nuinga o te hydroxypropyl methyl cellulose ether (HPMC).Hydroxypropyl methyl cellulose i roto i te hanga moata maroke HPMC te nuinga whai wāhi i roto i te pupuri wai, thickening, te whakapai ake i te mahi hanga.
1, hanga moata raima moata
Ko te pupuri i te wai teitei ka taea te whakakii i te raima, te whakanui ake i te kaha o te here, ka taea te whakapai ake i te kaha me te kaha kutikuti, te whakapai ake i te paanga o te hanga, te pai o te mahi.
2, putty ātete wai
I roto i te putty HPMC hydroxypropyl methyl cellulose ether te nuinga o te mahi ki te pupuri i te wai, te honohono me te whakahinuhinu, ki te karo i nga ahuatanga o te kapiti me te matewai na te tere rawa o te mate o te wai, me te whakarei ake i te piri o te putty, te whakaiti i te ahua o te rere iri ki roto. te hanga, kia ahua maeneene te hanga.
3, peita gypsum raupapa
I roto i nga raupapa gypsum o nga hua HPMC hydroxypropyl methyl cellulose ether te nuinga o te takaro i te pupuri wai, te whakanui ake i te whakahinuhinu me etahi atu paanga, i te wa ano he roa te paanga, ki te whakaoti i te hangahanga o te pahū pakaru, ko te kaha tuatahi kaore i te raruraru, ka taea te roa. te wa mahi.
4, kaihoko atanga
Ko te nuinga o te whakamahi hei whakapakeke, ka taea te whakapai ake i te kaha me te kaha kutikuti, te whakapai ake i te paninga o te mata, te whakarei ake i te piri me te kaha hononga.
5, mota whakamatao o waho
HPMC Hydroxypropyl methyl cellulose, cellulose ether i roto i te arotahi rauemi i runga i te hononga, te whakanui ake i te kaha, kia maamaa ake mo te paninga kumete, te whakapai ake i te pai o te mahi, i te wa ano ka nui ake te aukati rere poutū, te mahi pupuri wai teitei ka taea te whakaroa i te wa mahi o te kumete, te whakapai ake i te whakaheke me te waiariki rohirohi ātete, te whakapai ake i te kounga mata, te whakapai ake i te kaha hononga.
6, herea taera uku
Ko te pupuri i te wai teitei e kore e taea te ruku i mua i te makuku ranei i te taera raima me te turanga, ka tino whakapai ake i te kaha o te here, ka taea e te slurry te huringa hanga roa, te ngawari, te kakahu, te hanga watea, me te pai o te aukati ki te makuku.
7, kaihoko whakakī tui, kaihoko hono
Ko te taapiri o te hydroxypropyl methyl cellulose HPMC cellulose ether he pai te piri o te mata, te iti o te whakaheke me te kaha o te kakahu, te tiaki i nga mea turanga mai i te kino o te miihini, ki te karo i te paanga o te whakaurunga ki te whare katoa.
8, rauemi whakataurite whaiaro
Hydroxypropyl methyl cellulose cellulose ether stable here to ensure good liquidity and self-leveling ability, control water retention to be fast solidify, reduce cracking and contraction.
9. Te peita taherapa
Hydroxypropyl methyl cellulose i roto i te ahumahi paninga cellulose ether rite kiriata-mua, māngai thickening, emulsifier me te stabilizer whakamahia, kia he pai abrasion ātete, paninga, whakapiri, te whakapai ake i te kounga o te uara PH o te mānukanuka mata, me te pānga ranunga whakarewa organic he pai ake hoki, ko te mahi a Gao Baoshui he pai te paraihe me te rere o nga taonga.
10. Te honikoma uku
I roto i nga taonga hou o te honikoma, ka whakawhiwhia te pire ki te whakahinuhinu, te pupuri wai me te whakapakari kaha.
Ka taea e nga hua raupapa hydroxypropyl methyl cellulose pai te whakaoti i te raruraru o te pupuri wai i raro i te wera nui.I te wa teitei o te pāmahana, ina koa i nga waahi wera me te maroke me te hanga paparanga angiangi i te taha o te ra, ka hiahiatia te HPMC kounga teitei hei whakapai ake i te pupuri wai o te slurry.Ko te kounga teitei o te HPMC, he tino pai te whakakotahitanga, ko ona roopu methoxy me te hydroxypropyl i te taha o te cellulose molecular chain tohatoha orite, ka taea te whakapai ake i te here hydroxyl me te ether i runga i nga ngota hāora me te hononga wai te kaha here hauwai, hanga wai kore utu ki te wai whakakotahi, kia whai hua ai te whakahaere i te whakaetonga o te wai na te nui o te pāmahana o te rangi, kia pai ai te pupuri i te wai.
Ko te kounga teitei o te hydroxypropyl methyl cellulose ka taea te marara i roto i te kumete ciment me nga hua raima, ka kohia nga matūriki totoka katoa, ka hanga he paparanga o te kiriata makuku, ka tukuna te makuku i roto i te turanga mo te wa roa, me te tauhohenga wai pararopi. , kia rite ki te whakarite i te kaha here me te kaha compressive o rauemi.Na reira, i roto i te hanga raumati tiketike pāmahana, i roto i te tikanga ki te whakatutuki i te pānga o te tiaki wai, kia rite ki te tātai ki te tāpiri hua HPMC kounga teitei, ki te kore, ka maroke tere rawa na te iti o te hydration, te whakahekenga kaha, te pakaru, te pahū tuwhera me te hinga me etahi atu raruraru kounga, engari ka piki ake te uaua o nga kaimahi ki te hanga.I te hekenga o te pāmahana, ka taea te whakaheke haere i te nui o te HPMC, ka taea te whakatutuki i taua mana pupuri wai.
