He aha te hydroxypropyl methyl cellulose?

Hydroxypropyl methyl cellulose (HPMC), e mohiotia ana ano he hydroxypropyl methylcellulose, cellulose hydroxypropyl methyl ether, cellulose, 2-hydroxypropylmethyl ether, PROPYLENE GLYCOL ETER OF METHYLCELLULOSE, CAS No.Ka taea te wehewehea te HPMC ki te hanga whare, te karaehe kai me te karaehe rongoa e ai ki tana whakamahinga.Kei te whakamahia nuitia i roto i te hanga, te kai, te rongoa me te whakapaipai, nga matū o ia ra me etahi atu ahumahi.

He aha nga whakamahinga o te HPMC?

Te ahumahi hanga

1. Masonry mota
Ko te whakapakari i te piri ki te mata masonry ka taea te whakanui ake i te pupuri wai, na reira ka pai ake te kaha o te kumete, me te whakapai ake i te whakahinuhinu me te kirihou hei awhina i te mahi hanga.Ko te hanga ngawari ka whakaora i te wa me te whakapai ake i te pai o te utu.
2. Nga hua gypsum
Ka taea e ia te whakaroa i te wa mahi o te kumete me te whakaputa i te kaha miihini teitei ake i te wa whakakoi.Ko te paninga mata o te kounga teitei ka hangaia ma te whakahaere i te rite o te kumete.
3. Te peita wai me te tango peita
Ka taea e ia te whakaroa i te oranga o te papa ma te aukati i te rerenga totoka, he tino pai te hototahi me te pumau o te koiora.He tere te tere o te rewa, kaore i te ngawari ki te whakahiato, he pai ki te whakangawari i te mahi ranu.Te whakaputa i nga ahuatanga rere pai, tae atu ki te iti o te mokowhiti me te pai o te whakataurite, kia pai te whakaoti o te mata, me te aukati i te paheketanga o te peita.Whakanuia te pokey o te tango peita wai-wai me te tango peita wairewa pararopi, kia kore ai te tango peita e rere ki waho i te mata o nga mea mahi.
4. Te whakapiri tira uku
He ngawari te whakakotahi i nga kai whakaranu maroke me te kore e whakahiato, ka penapena i te waa mahi na te mea he tere ake te tono, he pai ake te mahi, he pai ake te mahi me te whakaiti i nga utu.Whakapai ake i te pai o te taera me te whakarato i te piri pai ma te whakaroa i te wa whakamahana.
5. Whakatauritenga ake i nga rawa papa
Ka whakarato i te pokey ka taea te whakamahi hei taapiri anti settling hei awhina i te pai o te papa.Ko te whakahaere i te pupuri wai ka tino whakaiti i nga kapiti me te whakaheke.
6. Production o papa raima hanga
Ka whakanui ake i te kaha o te mahi o nga hua kua puta, he kaha te hono me te whakahinuhinu, me te whakapai ake i te kaha maku me te piri o nga pepa kua tangohia.
7. Pereti whakakī hononga
Ko te Hydroxypropyl methyl cellulose he pai te pupuri i te wai, ka taea te whakaroa i te waa whakamahana, a, na tona whakahinuhinu teitei ka pai ake te tono.He pai ake te whakapai ake i te kounga o te mata, he maeneene, he kakano hoki, ka tino pakari te mata hono.
8. Sima i runga i te gypsum
He nui te pupuri i te wai, ka roa te wa mahi o te kumete, ka taea hoki te whakahaere i te urunga o te hau, na reira ka whakakore i nga kapiti moroiti o te paninga me te hanga i te mata maeneene.

Te ahumahi kai

1. Citrus kēne: ki te ārai whitening me te kino e tika ana ki te pirau o citrus glycosides i roto i te rokiroki, kia rite ki te whakatutuki i te hua pupuri hou.
2. Hua hua matao: ka tapirihia ki te wai hua me te hukapapa kia pai ake te reka.
3. Ranu: whakamahia hei whakaehunga whakaehunga, hei whakakaha ranei i te ranu me te whakapiri tōmato.
4. Te paninga wai matao me te whakakorikori: whakamahia mo te rokiroki ika tio hei aukati i te paheketanga me te paheketanga o te kounga.Whai muri i te paninga me te oro ki te methyl cellulose, hydroxypropyl methyl cellulose wairewa wai, whakatio ki runga i te paparanga tio.
5. Te whakapiri mo nga papa: Hei whakapiri mo nga papa me nga kowhatu, he pai te "tiango kotahi" (tere te whakakore, te tiango me te marara ina tango).

Te ahumahi rongoa

1. Whakakapi: Ka hangaia te kaihoko whakauru hei otinga o te whakarewa pararopi, he wairewa wai ranei mo te whakahaere papa, ina koa mo te rehu rehu o nga matūriki kua rite.
2. Kaihoko whakaheke: 2-3 karamu ia ra, 1-2G ia wa, mo nga ra 4-5.
3. Te rongoa Ophthalmic: I te mea he rite te pehanga osmotic o te wairewa wai methyl cellulose ki tera o te roimata, he iti ake te whakapataritari ki nga kanohi.Ka whakauruhia ki roto i te rongoa ophthalmic hei whakahinuhinu mo te whakapiri ki te arotahi kanohi.
4. Tiēre: Kei te whakamahia te reira rite te rauemi turanga o tiēre rite rongoa waho hinu hinu ranei.
5. Kaihoko whakapoipoi: whakamahia hei whakakaha me te pupuri wai.

Te ahumahi whakapaipai

1. Shampoo: Whakapai ake i te viscosity me te mirumiru o te shampoo, te horoi horoi me te hopi.
2. Toothpaste: whakapai ake i te rere o te toothpaste.

ahumahi kiln

1. Rauemi hiko: i te mea ko te perehi te hanga piri o te raima hiko hiko me te ferrite bauxite aukume, ka taea te whakamahi tahi me te 1.2-propanediol.
2. Te rongoa glaze: whakamahia hei rongoa ngiha o nga uku me te whakakotahi ki te peita tohu, ka pai ake te honohono me te mahi.
3. Moata whakaahuru: Ka taea te taapiri atu ki te pereki pereki whakaahuru, ki te maka ranei i nga mea oumu hei whakapai ake i te kirihou me te pupuri wai.

Ētahi atu ahumahi

Kei te whakamahia nuitia te HPMC ki te kapia waihanga, te petrochemical, te raima, te hanga pepa, te hiako, te waituhi wai, te tupeka me etahi atu ahumahi.Kei te whakamahia hei whakamaroke, whakamarara, here, emulsifier me te whakapumau i roto i te umanga pueru.

Me pehea te whakatau kanohi i te kounga o te hydroxypropyl methyl cellulose (HPMC)?

1. Chromaticity: ahakoa e kore e taea te tautuhi tika mehemea he ngawari ki te whakamahi i te HPMC, a, ki te taapirihia te kaihoko ma te hanga, ka pa te kounga.Heoi, kua tata ki te hoko nga hua kounga teitei.
2. Te Maamaa: E 80 nga mata o te HPMC me te 100 nga mata i te nuinga, me te 120 nga mata he iti ake.Ko te nuinga o nga HPMC he 80 nga mata.Ko te tikanga, he pai ake te pai o waho.
3. Whakawhiti marama: hoatu hydroxypropyl methyl cellulose (HPMC) ki roto i te wai kia hanga he colloid puataata, katahi ka kite i tona tukunga marama.Ko te nui ake o te whakawhiti marama, ko te pai ake, e tohu ana he iti ake te matū korekore i roto.
4. Te taumahatanga motuhake: Ko te taumaha ake o te taumahatanga motuhake, ko te pai ake.He mea nui te ōwehenga, i te nuinga o te waa na te mea he tiketike te ihirangi o te hydroxypropyl.Mena he nui te ihirangi o te hydroxypropyl, he pai ake te pupuri i te wai.
Ko te Hydroxypropyl methyl cellulose he pumau ki nga waikawa me nga turanga, a he tino pumau tona otinga wai i roto i te awhe o te pH = 2 ~ 12.He kaihanga ngaio matou.Mena ka hiahia koe ki tenei hua, ka taea e koe te whakapiri mai ki a maatau.Heoi ano mo te tohatoha o HPMC i tenei putanga.Ko taku tumanako ka awhina koe ki te mohio ki te HPMC.
