Mo te hydroxypropyl methylcellulose i te wa e whakamahia ana te paura putty

1. Nga raruraru noa i te paura putty

[Te whakamaroke tere] Ko te nuinga o tenei e pa ana ki te nui o te paura konupūmā pungarehu i tapirihia (he nui rawa, ka taea te whakaiti i te nui o te paura konupūmā pungarehu e whakamahia ana i roto i te tauira putty) me te tere o te pupuri wai o te hydroxypropyl methylcellulose (HPMC), a e pa ana hoki ki E pa ana ki te maroke o te pakitara.

[Te kiri me te koiri] E pa ana tenei ki te reiti pupuri wai. Ko te Hydroxypropyl methylcellulose (HPMC) he iti te viscosity, he ngawari ki tenei ahuatanga, he iti ranei te nui o te taapiri.

[Ko te tango i te paura o te paura putty pakitara o roto] E pa ana tenei ki te nui o te puehu konupūmā konupūmā i tāpirihia (he iti rawa te nui o te paura konupūmā pungarehu i roto i te tātai putty he iti rawa ranei te parakore o te paura konupūmā pungarehu he iti rawa, me te nui o te pungarehu. Ko te paura konupūmā i roto i te tātai paura putty kia tika te whakanui ake) I te wa ano, e pa ana ki te nui me te kounga o te hydroxypropyl methylcellulose (HPMC), e whakaatuhia ana i roto i te tere o te pupuri wai o te hua. He iti te tere o te pupuri i te wai, a ko te konupūmā konupūmā i roto i te pungarehu konupūmā paura e kore e tino whenumi Calcium hydroxide conversion hydration) te wa e kore e ranea, ka puta.

[Blistering] E pa ana tenei ki te makuku maroke me te papatahi o te pakitara, me te hanga hoki.

[Ka puta nga tohu pine] E pa ana tenei ki te cellulose, he kino nga ahuatanga o te hanga kiriata, me nga poke o te hydroxypropyl methylcellulose (HPMC) ka tauhoki paku ki te konupūmā pungarehu. Mena he kino te tauhohenga, ka puta te paura putty ki te tofu Slag state. Kaore e taea te whakanoho ki te pakitara, karekau he kaha whakakotahi i te wa ano. I tua atu, ka puta ano nga hua penei i te hydroxypropyl methylcellulose (HPMC) i konatunatua ki te roopu carboxymethyl i tenei ahuatanga.

[Ka puta mai nga ana puia me nga kohao titi] E kitea ana e pa ana tenei ki te mata o te wai o te wairewa wai hydroxypropyl methylcellulose (HPMC). Kaore i te kitea te maataki tepu wai o te wairewa wai hydroxyethyl. He pai ki te mahi maimoatanga whakaoti.

[Ko te putty he ngawari ki te pakaru me te huri kowhai i muri i te whakamaroketanga] E pa ana tenei ki te taapiri i te nui o te paura konupūmā pungarehu. Mena he nui rawa te taapiri o te paura konupūmā pungarehu, ka piki ake te pakeke o te paura putty i muri i te whakamaroketanga. Ko te pakeke karekau he ngawari ka ngawari ka ngatata, ina koa Ka pakaru ake ina pa ana ki te kaha o waho. E pa ana hoki ki te nui o te konupūmā konupūmā i roto i te pungarehu konupūmā paura.

2. He aha te mea ka angiangi te paura putty i muri i te taapiri wai?

Ko te Hydroxypropyl methylcellulose (HPMC) e whakamahia ana hei whakakaha me te pupuri wai i roto i te hinu. Na te thixotropy o te hydroxypropyl methylcellulose (HPMC), te hydroxypropyl methylcellulose i roto i te paura putty Ko te taapiri o te HPMC i puta ano te thixotropy i muri i te taapiri wai ki te putty. Ko tenei thixotropy na te whakangaromanga o te hanganga whakakotahitanga o nga waahanga i roto i te paura putty. Ka ara ake tenei hanganga i te okiokinga ka pakaru i raro i te ahotea. Arā, ka heke te pōkākā i raro i te whakakorikori, ā, ka hoki anō te pōkākā ina tū tonu.

3. He aha te take i tino taumaha ai te putty i roto i te mahi weriweri?

I tenei take, he tiketike rawa te pokey o te hydroxypropyl methylcellulose (HPMC) i te nuinga o te waa, a ka whakamahia e etahi kaihanga 200,000 yuan hei hanga putty. Ko te putty i mahia penei he nui te pokey, no reira ka totohu i te wa e waruhia ana te puranga. he ahua o. Ko te nui o te putty e taunaki ana mo nga pakitara o roto ko te 3-5 kg, me te pokey he 80,000-100,000.

4. He aha koe i whakaaro ai he rereke te pokey o te hydroxypropyl methylcellulose (HPMC) me te pokey kotahi i te takurua me te raumati?

Na te waiariki waiariki o te hua, ka heke haere te viscosity o te putty me te moata me te piki o te pāmahana. Ka nui ake te mahana i te mahana o te reera o te hua, ka heke te hua mai i te wai ka ngaro tona pokey. Ko te pāmahana o te rūma i te raumati kei runga ake i te 30 nga nekehanga, he rereke ke atu i te pāmahana i te takurua, no reira ka iti ake te pokey. E taunaki ana ki te whiriwhiri i tetahi hua me te kaha ake o te viscosity i te wa e tono ana i te hua i te raumati, ki te whakanui ake ranei i te nui o te hydroxypropyl methylcellulose (HPMC), me te whiriwhiri i tetahi hua he teitei ake te wera o te reera.
